New research published in the journal Geophysical Review Letters shows that relatively small volcanic eruptions can increase aerosol particles in the atmosphere, temporarily mitigating the global warming caused by greenhouse gases. The impact of these smaller eruptions has been underestimated in climate models and helps to explain the apparent slowdown in the pace of global warming recorded over the last 10 to 15 years, according to lead authors David Ridley, a CEE postdoc, and Professor Susan Solomon of Earth, Atmospheric and Planetary Sciences, and 15 other authors. The team found that small eruptions produce a significant amount of aerosol particles that reflect sunlight in a poorly monitored region of the upper atmosphere. This new information will be incorporated into the latest climate models to provide better estimates of global climate change over the coming decades, Ridley said.

Reliable predictions of the best commuting routes could save time and energy under normal conditions, and could save lives during emergency evacuations following a natural disaster. Writing in the journal Nature Communications, researchers including Professor Marta Gonzalez and including Zoltan Toroczkai and Yihui Ren at Notre Dame, have devised what they call an effective and relatively simple formula for making such predictions. They use a computer modeling system called a radiation model, which easily handles transportation changes such as construction or emergencies, and can be applied in areas with little initial data. In disaster situations, Gonzales says the model might make it easier “to know how the system is going to be disrupted,” and identify critical points that may produce bottlenecks.

Graphene’s exceptional mechanical and electronic properties make it a perfect candidate for applications such as flexible electronics and supercapacitors for energy storage, but its single-atom thickness also means it wrinkles easily, which could affect its ability to store a charge. Recently, a team including Dr. Zhao Qin, Professor Markus Buehler and Course 1 sophomore Mary Hwang have revealed for the first time that only two percent of the surface area of graphene is affected by wrinkles. To confirm this result, Zhao and Hwang have conducted an atom-by-atom analysis of the mechanics of graphene wrinkling, and developed a continuum mechanics model for different graphene geometries, sizes and loading conditions. This study provides important insights into the deformation of graphene, as well as efficient tools for designing the next generation of graphene nano-electronics.

The 550,000 miles of undersea fiber-optic cables that transmit e-mail and other data around the world are typically unfurled from large spools on ships. A rip or tangle anywhere can lead to transmission glitches and data loss, and significantly slow down global telecommunications. Now Professor Pedro Reis and colleagues at MIT and Columbia University have developed a method to predict the pattern of coils and tangles that a cable may form when deployed onto a rigid surface. The researchers say the coil-predicting method, which is based on model experiments, scaling analyses and computational tools that were originally developed in the context of computer animation for the movies to simulate the motion of hair and clothing, may help design better deployment strategies for the cables to avoid damage and increase their resilience.

Contrary to the traditional view that corals passively depend on ocean currents to deliver sustenance, Professor Roman Stocker and colleagues discovered that the organisms actually engineer their environment to sweep water into turbulent patterns and greatly enhance their ability to exchange nutrients and dissolved gases. In a paper in the Proceedings of the National Academy of Sciences, the researchers report that cilia, the threadlike hairs that push water along the coral surface, produce strong swirls of water that draw nutrients toward the coral while driving away potentially toxic waste products. Knowing that the boundary between coral and water is a dynamic environment will be important for studying the interactions of marine microorganisms with coral colonies, an important subject due to a global increase in coral disease and reef degradation. Besides illuminating how coral reefs function, Stocker suggests that this research could be of interest in studying other organisms with cilia, including inside human airways where cilia help to sweep away contaminants.

Interactions between rising temperatures and air pollution could significantly reduce food production around the world, according to an article by Professor Colette Heald, former postdoc Amos Tai, and Maria van Martin (Colorado State University) in the journal Nature Climate Change. While it is known that both higher temperatures and ozone pollution can lower crop yields, “nobody has looked at these together,” said Heald. They investigated global production of rice, wheat, corn and soy, and predicted that damage could be substantial but will vary considerably depending on the crop and the region. Any yield reductions would exacerbate the problems of feeding a growing population with higher dietary expectations.

Although materials that are firmly bonded together with epoxy and other adhesives are ubiquitous in modern life, from dental crowns to reinforced concrete, it is remarkably difficult to study. Now, a paper in the journal Proceedings of the National Academy of Sciences by Professors Oral Buyukozturk and Markus Buehler, doctoral student Denvid Lau (now an Assistant Professor at the City University of Hong Kong), and research associate Kurt Broderick of MIT’s Microsystems Technology Laboratories reveals the crucial role of moisture in setting the stage for failure. By looking at the molecular level, the group came up with an innovative method to measure the interface weakening as a result of exposure to environmental effects. Buyukozturk says, “I think this is going to be an important step toward assessment of the bonding, and enable us to design more durable composites.” Read the full MIT News Office story: http://newsoffice.mit.edu/2014/research-reveals-how-bonded-materials-los...

Nobody really knows how the trillions of bacteria living in each person’s digestive tract affect human health. As described recently in the journal Genome Biology, Professor Eric Alm and colleagues charted fluctuations in bacterial populations in two research subjects for a year, and found that specific dietary and lifestyle changes produced specific daily variations in the populations of different bacteria. Eventually it might be possible to generate data that could produce a personalized monitoring system for people suffering from diseases that occasionally flare up, such as inflammatory bowel disease. The monitoring system might be able to detect an oncoming flare-up and recommend dietary changes to help avert trouble.

A paper by graduate student Yingxiang Yang, Professor Marta Gonzalez and others in the July 11 issue of Scientific Reports explains how to calculate the number of short and long commuting trips when detailed trip data is not available. They found that cell phone records from Rwanda and other countries can provide this information on a population’s commuting patterns. Compared with empirical trip data from the United States, their model’s estimation accuracy is as good as other existing models that depend on data for calibration. Obtaining quality estimates of how many people frequently travel between two places is a key ingredient for transportation planning, facility distribution and modeling the spread of infectious diseases.

Although algae produce large quantities of lipids that can be extracted and converted into biodiesel, breaking apart the algae to recover the lipids is costly and energy-intensive. Recent research in Penny Chisholm’s lab on the oceanic bacterium Prochlorococcus determined that it naturally releases vesicles containing related fatty oils. Even better, the vesicles could be collected without destroying the cells. While the lipids in the vesicles are not the optimal kind for making biofuels, postdoctoral associate Steven Biller notes that Prochlorococcus is “a good model to use in exploring the mechanisms that control the formation and extrusion of vesicles and determine their content.” Read the full MIT News story: http://newsoffice.mit.edu/2014/ocean-microbes-display-hidden-talent-releasing-countless-tiny-lipid-filled-sacs

In a recent paper in Science, Professor Edward DeLong and colleagues report that microbes in the open ocean follow predictable patterns of biological activity throughout the day, such as eating, breathing, and growing. DeLong says. “What we’re seeing out in the ocean tells us how complex assemblages of different microorganisms are basically working together and coordinating their activities with time.” Improvements in genome sequencing technologies make it possible to “sequence a lot deeper into the microbial community’s gene transcripts at each time point, so we’re getting closer to the resolution of where activities really matter.” Read the full MIT News story: http://newsoffice.mit.edu/2014/ocean-bacteria-follow-predictable-patterns-daily-activity-0710

After injuries derailed his prospects for playing professional soccer, Leon Dimas changed course and is now a PhD student working to create resilient new materials based on natural substances. He and two other MIT graduate students founded MITxplore, an afterschool program for local fifth graders to encourage learning math through experimentation and exploration. In his doctoral research, Dimas creates models that predict the fracture response, fracture resistance, and durability of synthetic materials that arranged their ingredients in various natural and synthetic geometries. Such work could eventually lead to new “metamaterials” that combine nature’s designs with human engineering, resulting in cars or buildings constructed from superstrong synthetic skeletons.

Dimples on a golf ball dramatically increase the distance it can travel by reducing the drag caused by air resistance. As reported in the journal Advanced Materials, MIT researchers including Professor Pedro Reis and former postdocs Denis Terwagne and Miha Brojan, hope to similarly reduce drag on a variety of other surfaces. Their experiments showed how on-demand changes in surface texture on rubberlike balls enabled them to switch and tune the degree of drag reduction. Future applications suggested by Reis might include adjusting the texture of panels on auto exteriors for different speeds to minimize drag and boost fuel efficiency. Read this news story.

Drivers frustrated by red lights at each intersection can take heart that Professor Carolina Osorio and graduate student Linsen Chong have developed a better way to compute optimal timing of city stoplights. Osorio is the lead author of a forthcoming paper in the journal Transportation Science that describes the new system, based on a study of traffic in Lausanne, Switzerland. The new optimization process uses high-resolution traffic simulators that provide detailed descriptions of how 12,000 simulated drivers respond to changes in travel conditions, rather than treating them as a simple homogeneous group. This method showed that better timing could reduce average travel time by 22 percent, compared with results from commercial traffic-light timing software. Read this MIT News story.

Eumelanin, a form of the pigment melanin, not only determines our skin and eye coloring but also protects us from ultraviolet and other damaging radiation. Now researchers at MIT and other institutions, including Professor Markus Buehler, graduate student Chun-Teh Chen, and colleagues from the MIT Department of Chemistry have discovered exactly how it blocks a broad spectrum of sunlight so effectively. Using first-principles computation and experimental analysis to derive the molecular structure and optical properties of the material, they found that a key source of the broadband absorption is the geometrical arrangement of the constituents, not their chemical characteristics. This work, published in Nature Communications, could potentially lead to the development of synthetic materials with similar light-blocking and other designer optical properties.

Every senior at MIT has come to know the campus in a personal way, having established favorite haunts for studying, eating, resting and playing during their four years at the Institute. But the Course 1 Class of 2014 is getting to know the campus on an even more intimate level, and wants to share that with others. These students just completed deployment of a highly sophisticated air-quality monitoring network that covers most of the 0.25-square-mile campus. The network, called CLAIRITY, has 24 indoor and outdoor sensor nodes that continuously measure gases and the small particles found in air pollution and send these data via wireless to a central computer. They formally launched the network and its web portal in a public presentation May 6. The network represents two semesters of work for the students, who designed, built and deployed the network as the capstone project in the CEE engineering design subject. Read a news story.

Course 1 seniors will demonstrate CLAIRITY — the air-quality sensor network they designed, built and deployed across campus — in a public presentation Tuesday, May 6 at 4 p.m. in Room 46-3002. The network is made up of 25 indoor and outdoor sensor nodes that measure gases and particles and transmit data wirelessly to a central server. The system is unique in that it measures air quality in many locations simultaneously. This is important because pollutant levels can vary dramatically from area to area, says Professor Jesse Kroll, who teaches the subject with Professor Colette Heald and lecturer Eben Cross. Boston, by comparison, has only five monitoring stations to measure air quality throughout the city’s 48 square miles. Read a story.

A study by CEE Professor Lydia Bourouiba and Professor John Bush of mathematics shows that coughs and sneezes have associated gas clouds that keep their potentially infectious droplets aloft over much greater distances than previously realized. The study finds the smaller droplets that emerge in a cough or sneeze may travel five to 200 times further than they would if those droplets simply moved as groups of unconnected particles — which is what previous estimates had assumed. The tendency of these droplets to stay airborne, re-suspended by gas clouds, means that ventilation systems may be more prone to transmitting potentially infectious particles than had been suspected. With this in mind, architects and engineers may want to re-examine the design of workplaces and hospitals, or air circulation on airplanes, to reduce the chances of airborne pathogens being transmitted among people.

Professor Philip Gschwend describes the “legacy of problems buried in our environment” that often arise as side effects of products — such as PCBs and catalytic converters — designed to solve already existing problems. His research group has developed inexpensive sheets of polyethylene that can be placed in mud or water to soak up chemicals and measure their availability as they move through the environment. But the real answer, he says, is to prevent such problems in the first place by involving environmental chemists at the outset of materials and chemicals design.

Marine cyanobacteria — tiny ocean plants that produce oxygen and make organic carbon using sunlight and CO2 — are primary engines of Earth’s biogeochemical and nutrient cycles. They nourish other organisms through the provision of oxygen and with their own body mass, which forms the base of the ocean food chain. Now postdoc Steven Biller and Professor Sallie (Penny) Chisholm have discovered another dimension of the outsized role played by these tiny cells: The cyanobacteria continually produce and release vesicles, spherical packages containing carbon and other nutrients that can serve as food parcels for marine organisms. The vesicles also contain DNA, and they may even act as decoys to deflect viruses. Read a news story.

Roughly a billion people worldwide live without safe drinking water and each year millions are sickened by waterborne diseases, a condition CEE Senior Lecturer Susan Murcott hopes to improve through dissemination of household drinking water treatment and safe storage systems, a cluster of innovative technologies she has helped invent and promote: one used by about 800,000 people in Guatemala; another that removes pathogens and clarifies turbidity in Ghanaian drinking water used by over 100,000 people; and a third, a filter sold in Nepal to screen out arsenic and bacteria, which has so far reached 350,000 people. All three projects make use of locally available materials and the local workforce to create jobs in manufacturing and sales. Many CEE Masters of Engineering students, School of Engineering, DUSP and Sloan students have worked with Murcott on these projects, which were showcased at the Expo Bid Symposium in October in Dubai and will be honored during the World Expo 2020 in Dubai.

Hidden risk in supply chains: Analytical study finds no link between expenditures and supply-chain risk
December 16, 2013
A new study by CEE Professor David Simchi-Levi helps explain why risk in a complex supply-chain network often remains hidden. There’s no correlation between the total amount a manufacturer spends with a supplier and the profit loss it would incur if that supply were suddenly interrupted. This counterintuitive finding defies a basic business tenet that equates the greatest supply-chain risk with suppliers of highest annual expenditure. When applied to Ford Motor Company’s supply chain, the quantitative analysis shows that the supply firms whose disruption would inflict the greatest blow to Ford’s profits are those that provide the manufacturer with relatively low-cost components.

Coral reefs, the most biodiverse ecosystems in the world’s oceans, are declining because of bleaching and disease. But little is known about the microscale interactions between the pathogens that cause disease and the weakened coral. Now CEE’s Professor Roman Stocker, postdoc Melissa Garren and grad student Kwangmin Son have identified one mechanism by which pathogenic bacteria identify their prey: The stressed coral produce up to five times more of a sulfurous compound called DMSP. The abundant DMSP appears to serve as a clarion call, inciting the pathogen cells, which sense the amplified chemical and charge in for attack, changing their swimming direction and speed as they home in on the weakened coral.

Could the path to a more sustainable future be paved in concrete? Researchers at MIT’s Concrete Sustainability Hub (CSHub) certainly think so. By investigating cement and concrete from the nanoscale up and considering its full life cycle, they are working to reduce the energy footprint of the world’s most common building material. “The per-unit weight impact of concrete on CO2 levels is low; but since each person on the planet consumes 1 cubic yard of concrete each year, the aggregate impact is substantial,” said Franz-Josef Ulm, faculty director of the CSHub and the George Macomber Professor of civil and environmental engineering. Indeed, the production of cement powder, the primary ingredient of concrete, accounts for 5 to 10 percent of global CO2 production annually. Read a story.

Motivated by aquatic flowers, Professors Pedro Reis (CEE and MechE) and John Bush (Mathematics) recently designed an upside-down floral pipette whose petals grab liquid as they close. This mechanism was inspired by the behavior of water lilies, which float at the surface of ponds or lakes while anchored to the floor. As water rises, hydrostatic and surface tension forces act to bend and eventually close the lily’s petals, thereby preventing water from flooding in. Reis's upside-down flower pipette does the opposite, grabbing water as it’s pulled up, thereby reversing the role of gravity. (This work was published in Soft Matter online Oct. 14, 2010.) The researchers calculated the optimal petal size for capturing a small sip of liquid and then fabricated synthetic flowers through casting, each of which is about 35 millimeters wide — about the size of a small dandelion. This liquid grabber design is now being used by Spanish José Andrés, one of the world’s leading chefs, as a means of serving a palate-cleansing liquid between courses.

The November issue of the On Balance newsletter describes a study led by Professor David Simchi-Levi that provides a new quantitative model for analyzing a corporation’s supply chain risk. Surprisingly, the study shows no correlation between the total amount a manufacturer spends with a supplier and the profit loss it would incur if that supply were suddenly interrupted. This finding goes against traditional business thinking, which equates the greatest supply chain risk with suppliers of highest annual expenditure. When applied to Ford Motor Company’s supply chain, the analysis shows that the supply firms whose disruption would inflict the greatest blow to Ford’s profits are those that provide the manufacturer with relatively low-cost components.

As public-health officials continue to fight malaria in sub-Saharan Africa, researchers are trying to predict how climate change will impact the disease, which infected an estimated 219 million people in 2010. But projections have been hampered by wide variation in rainfall predictions for the region and lack of a malaria-transmission model that adequately describes the effects of local rainfall on mosquitos. A new study by Professor Elfatih Eltahir and graduate student Teresa Yamana solves this problem by combining a model of malaria transmission with global forecasts for temperature and rainfall. They found that although the capacity for malaria transmission will change in some areas of West Africa, overall infection rates are not likely to increase. Climate change by itself is not likely to make the situation worse. Read a news release.
Public discussion and private sector involvement on Hyperloop could speed up the usual design process, writes Saurabh Amin
August 14, 2013
In an opinion piece for CNN, Professor Saurabh Amin likens Elon Musk's request for public comment on the design of the Hyperloop — an ambitious high-speed transportation system — to open source web programming, saying that collective design could speed up the process. "But just as today's open source product designs on the web have benefited and improved from the collective effort of programmers, so has Musk decided to confront the design bottleneck by opening up the design process to the general public — anyone and everyone who cares."

In an epidemic or a bioterrorist attack, the response of government officials could range from a drastic restriction of mobility to simple suggestions that people remain at home. Deciding to institute any measure would require officials to weigh the costs and benefits of action, but at present there’s little data to guide them. However, a new study by Professor Ruben Juanes, graduate student Christos Nicolaides and research associate Luis Cueto-Felgueroso shows that even moderate measures of mobility restriction would be effective in controlling contagion in densely populated areas with highly interconnected road and transit networks. The researchers called the difference between infection rates in the two scenarios the “price of anarchy,” a concept from game theory that’s frequently used as a metric in studies of transportation networks.

Understanding the strength of a mussel’s underwater attachments could enable better glues and biomedical interfaces
July 29, 2013
Unlike barnacles, which cement themselves tightly to surfaces, the bivalves called mussels dangle more loosely, attached by a collection of fine filaments known as byssus threads. This approach lets the creatures drift further out into the water, where they can absorb nutrients. Despite the outwardly thin and fragile appearance of these threads, it turns out that in the dynamic, sloshing environment of waves and currents they can withstand impact forces that are nine times greater than the forces exerted by stretching in only one direction. The secret to these tiny natural bungee cords has now been unraveled by research scientist Zhao Qin and professor of civil and environmental engineering Markus Buehler. Their findings appeared last week in the journal Nature Communications. Read a news story.

Tiny ocean plants, or phytoplankton, were long thought to be passive drifters in the sea — unable to defy even the weakest currents, or travel by their own volition. In recent decades, research has shown that many species of these unicellular microorganisms can swim, and do so to optimize light exposure, avoid predators or move closer to others of their kind. Now Professor Roman Stocker, William Durham Ph.D. ’12 and grad student Michael Barry have shown that the motility of phytoplankton also helps them determine their fate in ocean turbulence. Rather than acting to distribute them evenly — as physics would demand of small particles mixed into a fluid — the individual vortices that make up ocean turbulence are like social mixers for phytoplankton, bringing similar cells into close proximity, potentially enhancing sexual reproduction and other ecologically desirable activities.

Bacteria swim by rotating the helical, hairlike flagella that extend from their unicellular bodies. Some bacteria have multiple flagella that rotate as a bundle to move the cell forward. These cells turn somewhat acrobatically by unbundling their flagella, causing the cell to tumble, reorient and strike out in another direction. But 90 percent of motile marine bacteria have only a single rigid flagellum. These microbes change direction with a sideways “flick” of their flagellum — a unique swimming stroke first documented in 2011 whose mechanism has been a mystery. Now, using high-speed video to record individual swimming bacteria at up to 1,000 frames per second, Professor Roman Stocker, Kwangmin Son and Jeffrey Guasto show that the flick occurs when the so-called “hook,” a flexible rod connecting the flagellum to the cell’s internal motor, buckles during forward swims. The drag on the cell head caused by the water’s resistance combines with the opposing thrust force from the rotating flagellum to compress the hook, causing it to buckle and flick the cell into a 90-degree reorientation.

Researchers working to design new materials that are durable, lightweight and environmentally sustainable are increasingly looking to natural composites, like bone, for inspiration. Bone is strong and tough because its two constituent materials, soft collagen protein and stiff hydroxyapatite mineral, are arranged in complex hierarchical patterns that change at every scale of the composite, from the micro up to the macro. While researchers have come up with hierarchical structures in the design of new materials, going from a computer model to the production of physical artifacts has been a persistent challenge. Now Markus Buehler and team have developed an approach that allows them to turn their designs into reality. In just a few hours, they can move directly from a multiscale computer model of a synthetic material to the creation of physical samples. Read a news story.

As part of the "broader impacts" component of a National Science Foundation (NSF) research grant, two 1C undergrads and an alumna — junior Linda Seymour, sophomore Shante Stowell and Elise Hens '12 — are working with CEE lecturer Ari Epstein to make a series of three podcasts about the research of Professors Martin Polz and Scott Manalis (biological engineering) covered by the grant. Episode 1: World’s Tiniest Diving Board (8.5 minutes) tells how the researchers are using microfluidics technology and a miniature diving board to measure the mass of microbes to learn how much a microbe grows before it splits apart to replicate. Episode 2 will focus on the recent findings that microbes exhibit social cooperation, episode 3 on the ways scientists communicate their research findings — formally and informally — within the scientific community and to the public, and the final episode will summarize the research supported by the grant. Epstein said he hopes that other CEE principal investigators will want to incorporate similar projects in their NSF proposals. "It's a relatively low-cost and interesting opportunity for outreach that provides a nice educational experience for the undergraduates," said Epstein. The podcast series, “Measuring Marine Microbes,” is available on Soundcloud.

Professor Oral Buyukozturk of CEE and Professor William Freeman of electrical engineering and computer science (EECS) and the Computer Science and Artificial Intelligence Laboratory (CSAIL) are principal investigators (PIs) on an $8 million, five-year collaborative research project funded by Shell. The project builds on the concept of previous research on MIT’s Green Building, which has been instrumented with a sensor network that monitors the building’s response to disturbances and allowed researchers to determine its fundamental frequencies and ambient vibrations. With the new grant, through representative laboratory models and implementation studies on the real structure, the PIs will create a wireless version of the monitoring system, develop pattern recognition/motion magnification algorithms and build 3-D computational models that can predict a building’s response to disturbances and detect anomalies and damage. Co-PIs on the project are Professor Eduardo Kausel of CEE, Professor Edward Adelson and senior research scientist John Fisher of CSAIL, and Professor Fredo Durand of EECS and CSAIL. Draper Laboratory participates as a subcontractor. Read more about Green Building monitoring.

Studies of human mobility usually focus on either the small scale — individuals’ daily commutes — or the very large scale, such as using air-travel patterns to track the spread of epidemics over time. The large-scale studies, now made possible by vast data generated and collected by technologies like sensors and cellphones, are very good at describing the big picture, but don’t provide detail at the individual level. Smaller-scale studies have the opposite characteristic: their findings generally can’t be scaled up from the individual to populations. But a new study by CEE Professor Marta González and postdoctoral associate Christian Schneider bridges that gap. It uses big data and the methodologies of statistical physics and network theory to describe the daily travel behavior of individuals, behavior that holds true at the larger scale of the entire population of two cities on different continents.

Eric Adams, senior lecturer, senior research engineer and director of the CEE M.Eng.program, is the subject of a news story on the MIT Industrial Liaison Program (ILP) website. The article describes how Adams’ research in environmental fluid mechanics has helped engineers better understand oil spills. Specifically, his studies of multi-phase pollutants — fluid set in motion by the buoyancy of bubbles, droplets and particles — have provided important insights into what happens during a deep ocean oil spill. He has shown that most oil from an oil spill will mix with water instead of rising directly to the surface, disproving the adage that oil and water don’t mix. Adams is also working on ways to reduce the amount of atmospheric carbon dioxide by releasing carbon dioxide hydrates directly into the ocean.

Collaborative work by Professor Markus Buehler and postdoctoral associate Seunghwa Ryu and researchers at Duke University demonstrates the use of mechanical instabilities in graphene to reversibly control its surface properties. The researchers showed that substances like water droplets have a distinct way of interacting with graphene's surface by applying mechanical strain to the system, which in turn changes the nanoscale structure of the graphene film. Harnessing a nanoscale crumpling (or buckling) instability in graphene allowed the researchers to make the graphene's surface at the macroscale highly water repellent, creating a reversible “Lotus effect” that causes a water droplet to form a spherical shape and roll along the surface. Buehler and Ryu, now an assistant professor at Korea Advanced Institute of Science and Technology, worked on simulations and theory and the Duke researchers ran the lab experiments. Applications for this type of mechanical instability in graphene include superhydrophobic and on-demand self-cleaning surfaces, as well as electrodes that make use of graphene's electronic properties. The work was published online Jan. 20 in Nature Materials.

Scientists track ocean microbe populations in their natural habitat to create a ‘day in the life’ montage
January 22, 2013
Microbiologists who study wild marine microbes face enormous challenges in getting a clear picture of the daily activities of their subjects. But a team of scientists led by Professor Edward DeLong recently figured out how to make the equivalent of a nature film, showing the simultaneous activities of many coexisting species in their native habitat over time. Instead of making a movie, the scientists used a robotic device that drifted in the water gathering samples of one billion microbes every four hours. Similar to fast photography that stops action, the robotic device “fixed” each sample so that whatever genes the microbes were expressing at the moment of capture were preserved for later study in the lab, where the scientists created a time-lapse montage of the daily labors of microbes.

Zara L'Heureux, a senior in 1C, presented a poster at the American Association of Aerosol Research's (AAAR) annual meeting in October 2012 based on fieldwork research performed by civil and environmental engineering undergraduates in CEE's Traveling Research Environmental Experiences (TREX) January 2012 program. The poster, "Online, Mobile Measurements of the Chemical Composition of Volcanic Smog (Vog)," described the study, which aimed to characterize the evolving composition of vog from Kilauea, an active volcano on the island of Hawaii. The TREX 2012 team of 14 undergraduates used an SUV carrying a suite of real-time aerosol and gas phase monitors to intercept and sample vog at multiple locations downwind of the volcano. These are the first known real-time measurements of the composition of volcanic aerosol.
Vog has become a severe environmental problem on Hawaii since a new vent opened in Kilauea in 2008. Sulfur dioxide gas and particulate sulfate in the plume are blown south-southwest by tradewinds, greatly impacting the southern portion of the island, particularly the town of Pahola. On some days, the plume is then picked up by offshore winds and blown northward along the western shore, impacting Hilo, the largest city on the island. Students will continue the work this month during TREX 2013. Co-authors of the poster are Eben Cross, L'Heureux, Lisa Wallace, Anna Kelly, Kelly Daumit, Philip Croteau, John Jayne, Douglas Worsnop and Professor Jesse Kroll. Read more in the TREX 2012 blog.

Traffic congestion can be alleviated throughout a metropolitan area by altering the trips of drivers in specific neighborhoods
December 20, 2012
In most cities, traffic growth has outpaced road capacity, leading to increased congestion, particularly during the morning and evening commutes. One way to prevent traffic tie-ups is to have fewer cars on the road by encouraging alternatives such as public transportation, carpooling, flex time and working from home. But a new study — by Professor Marta González and researchers at Central South University in China, the University of California at Berkeley and the Austrian Institute of Technology — incorporates data from drivers’ cellphones to show that the adoption of these alternatives by a small percentage of people across a metropolitan area might not be very effective. However, if the same number of people, but from a carefully selected segment of the driving population, chooses not to drive at rush hour, this could reduce congestion significantly.

Research shows why slight increase in flexibility of manufacturing plants optimizes efficiency and cost
December 17, 2012
Professor David Simchi-Levi and doctoral student Yehua Wei applied a combination of optimization and stochastic methodologies to explain the effectiveness of “long chain” flexibility design in manufacturing operations. With the long chain design, manufacturing plants are endowed with the capacity to produce exactly two different products and every product is produced by exactly two plants. The design can be applied to other systems, including the cross-training of workers on an assembly line, supply chains, queuing networks, and people and tasks in a call center. But until now, nobody had explained or proved mathematically why the long chain works better than other flexibility models. Read the December issue of On Balance.

In late September, Professor Jerome Connor’s latest book was published, this one written with co-author Susan Faraji of University of Massachusetts Lowell. Fundamentals of Structural Engineering (Springer, 2013) is the sixth book Connor has authored or co-authored, but it is his first textbook for undergraduates. The 1,120-page book can be used for teaching three subjects: Structural Analysis I and II and Practice of Structural Engineering. Connor says his goal is to modify the teaching paradigm to incorporate computer-based computation and analysis into undergraduate curricula. “Engineers reason about behavior using simple models and intuition they’ve acquired through problem-solving experience,” says Connor. “The approach in this book will help students develop this type of intuition through computer simulation, which allows one to rapidly explore how the structure responds to changes in geometry and physical parameters.” Read the E-book online from within MIT or from outside MIT.

Oceanographers have long assumed that because turbulence distributes nutrients uniformly in ocean water, and because the ability of tiny organisms to move around is insignificant compared to this turbulence, there was no reason for ocean bacteria to move at all. Sea-dwelling bacterial life, they believed, should consist just of static feeders. That view has now been upended by research conducted by Professor Roman Stocker and John R. Taylor, a former postdoctoral associate. It turns out that swimmers and passive feeders each have some advantages — but also pay some costs — in food gathering. The results, based on a computer model that for the first time considers nutrient competition by bacteria in a turbulent flow, were published in the Nov. 2 issue of Science, along with a review article by Stocker about ocean microbes interactions with their environment.

Researchers in MIT’s Concrete Sustainability Hub are making steady progress toward learning exactly how the cement paste that works as glue in concrete hardens during the first hours after water and cement powder are mixed. First they determined that cement paste can be described as a granular aggregate, where the particles or basic nanoscale units pack together most densely when arranged orderly. A few years later they discovered that the calcium-silicate-hydrate (C-S-H) molecules that make up the basic nanoscale unit of cement have a disorderly geometric arrangement, rather than the orderly crystalline structure scientists had long assumed. In new work, they found that the size of C-S-H particles themselves is also somewhat disorderly. The particles form at random sizes, not in homogenous spheres, and the diversity in particle size leads to a denser, disorderly packing of the particles, which corresponds to stronger cement paste. A paper by CEE postdoctoral associate Enrico Masoero, Professor Franz-Josef Ulm, senior research scientist Roland Pellenq and co-authors appeared in the Oct. 12 issue of Physical Review Letters.

New research by Professor Markus Buehler and doctoral student Zhao Qin on the fracture mechanism of ice shows that ice cracks more easily when exposed to carbon dioxide. Using a series of atomistic-level computer simulations to analyze the dynamics of molecules, they found that carbon dioxide forms hydrogen bonds with ice at a crack boundary, then breaks those bonds as it moves toward the tip of the crack. When bonds break near the crack tip, the energy released weakens the ice and makes it more apt to fracture. The research could be used to study ice fracture in other chemical environments or even be scaled up and incorporated into models of glacier dynamics. A paper on this work appeared in the Oct. 11 issue of the Journal of Physics D: Applied Physics.

Competition is a strong driving force of evolution for organisms of all sizes; those individuals best equipped to obtain resources adapt and reproduce, while others may fall by the wayside. Many organisms also form cooperative social structures that allow resources to be defended and shared within a population. Surprisingly, even microbes have a somewhat sophisticated social structure that relies on cooperation, according to Professor Martin Polz and postdoctoral associate Otto Cordero. These researchers recently found evidence that some ocean microbes wield chemical weapons — antibiotics — that are harmless to close relatives within their own population, but deadly to outsiders. Three CEE undergrads are co-authors on the paper. Read news release.

Research by Professor David Simchi-Levi was the topic of an article in the July 18 issue of the Wall Street Journal. Simchi-Levi surveyed 108 U.S. manufacturing companies, mostly with annual sales over $1 billion, and found that about 14 percent plan to "reshore" or move some of their manufacturing back to U.S. soil. Several things influenced this decision, Simchi-Levi says, including the need to move products from plant to customer more quickly, reduce transportation and warehousing costs, and create jobs back home.

Public health crises of the past decade have heightened awareness that new viruses or bacteria could spread quickly across the globe, aided by air travel. While epidemiologists and scientists who study complex network systems are working to create mathematical models that describe the worldwide spread of disease, to date these models have focused on the final stages of epidemics, examining the locations that ultimately develop the highest infection rates. But a new study by Ruben Juanes, Marta González, Christos Nicolaides and Luis Cueto-Felgueroso shifts the focus to the first few days of an epidemic, determining how likely the 40 largest U.S. airports are to influence the spread of a contagious disease originating in their home cities.

A new study by Professor Franz-Josef Ulm and Ph.D. student Mehdi Akbarian shows that using stiffer pavements on the nation’s roads could reduce vehicle fuel consumption by as much as 3 percent — a savings that could add up to 273 million barrels of crude oil per year or $15.6 billion, at today’s oil prices, and a decrease in CO2 emissions. Ulm and Akbarian use mathematical modeling to look at the effect of pavement deflection on fuel consumption across the entire U.S. road network, and conclude that because of the way energy is dissipated, the maximum deflection of the load is behind the path of travel, making the tires on the vehicle drive continuously up a slight slope.

Professor Sallie W. (Penny) Chisholm of CEE and biology and Professor John Cullen of Dalhousie University will receive the American Society for Limnology and Oceanography's Ruth Patrick Award — which honors research in basic aquatic science that helps identify, analyze and/or solve environmental problems — for their "significant contributions to the global community in their foresight and effective efforts in addressing the environmental impacts of ocean iron fertilization," the citation said. Shortly after the idea surfaced in 1988 of using iron fertilization to prompt the growth of phytoplankton which might serve as a CO2 sink, Chisholm and Cullen co-chaired an international symposium to foster discussion on this topic among scientists. The conference ended with a resolution that, because of the potential damage that could result from such a large-scale experiment, iron fertilization should not be viewed as a method for solving the CO2 emissions problem. Chisholm and Cullen went on to write several influential articles on the science and policy dimensions of ocean fertilization.

In two papers appearing in March issues of the Proceedings of the National Academy of Sciences, Professor Roman Stocker and co-authors explore how the environment influences the movements of marine plankton. In “Low-Reynolds-Number Swimming at Pycnoclines” (layers of ocean water where density increases sharply with depth), the researchers describe how buoyancy increases the energy expenditure of motile microbes and stifles their nutrient uptake, but also increases their stealth, making their movements more difficult for predators to detect. In “Bacterial Rheotaxis,” the scientists discovered that a subtle interplay between a flow velocity gradient and the helical shape of a bacterium’s flagella generates a torque that alters the bacterium’s swimming direction, driving it off course in a microscale version of a baseball pitcher’s curveball.

Bacteria adapt to habitats through random genetic mutations and gene exchange. But how does an advantageous mutation spread from a bacterium to a population? Does the gene sweep through a population or does an individual bacterium obtain the gene, then replicate its genome many times to form a new and better-adapted population? Researchers including CEE Professors Eric Alm and Martin Polz and MIT alumnus Jesse Shapiro ’10 show that genes can sweep through populations on their own, indicating that the process of evolution in bacteria is very similar to that of sexual eukaryotes.

For more than half a century, people interested in modeling the movement of people and goods between cities, states or countries have relied on a statistical formula called the gravity law, which measures the “attraction” between two places. Though widely used, the gravity model isn’t very accurate in making predictions. Now CEE Professor Marta González and researchers from Northeastern University and the University of Padua have identified an underlying flaw in the gravity model: The distance between two cities is far less important than the population size in the area surrounding them. The team created a new model that takes human motives into account and in five types of mobility studies the new model’s predictions were far more accurate than the gravity model’s.

The silk that spiders use to build their webs, trap their prey and dangle from your ceiling is one of the strongest materials known. But it turns out it’s not simply the material’s exceptional strength that makes spider webs so resilient; it’s the material’s unusual combination of strength and stretchiness — silk’s characteristic way of first softening and then stiffening when pulled. These properties, scientists have found, vary depending on the forces applied, as well as on the overall design of the web. Professor Markus Buehler, graduate students Steven Cranford and Anna Tarakanova, and Nicola Pugno of the Politecnico di Torino in Italy find evidence of the key properties that make webs so resilient and relate those properties back to the molecular structure of silk fibers.

CEE researchers Professor Sallie (Penny) Chisholm and postdoctoral associate Qinglu Zeng have discovered that certain photosynthetic ocean bacteria need to beware of viruses bearing gifts. These viruses are really con artists carrying genetic material taken from their previous bacterial hosts that tricks the new host into using its own machinery to activate the genes, a process never before documented in any virus-bacteria relationship. The con occurs when a grifter virus injects its DNA into a bacterium living in a phosphorus-starved region of the ocean. Read a news release.

CEE postdoc finds that pulling CO2 from the air would not be cost-effective in the foreseeable future
January 3, 2012
Since most of the world’s governments have not yet enacted regulations to curb emissions of greenhouse gases, some experts have advocated the development of technologies to remove carbon dioxide directly from the air. But a new MIT study co-authored by CEE postdoc Kurt Zenz House (who works in Professor Charles Harvey's lab) shows that, at least for the foreseeable future, such proposals are not realistic because their costs would vastly exceed those of blocking emissions right at the source, such as at the powerplants that burn fossil fuels.

All biological sensory systems, including the five human senses, have something in common: when exposed to a sustained change in sensory input, the sense eventually acclimates and notices subsequent changes without comparing them with the initial condition. This autonomous tuning of perceptions, known as sensory adaptation, has been recognized for more than a century. A new study by Professor Roman Stocker, Tanvir Ahmed Ph.D. ’11 and co-authors demonstrates that even microbes have sensory adaptation so precise that their behavior remains identical in ever-changing background conditions.

Study takes a micro-mechanics approach to understanding how water impacts fiber-wrapped concrete structures
July 11, 2011
Professors Oral Buyukozturk and Markus Buehler, doctoral student Denvid Lau and recent graduate Chakrapan Tuakta Ph.D. '11 used molecular dynamics simulation to study how materials interact at the molecular level and recently applied it for the first time to the interface between epoxy and silica, one of the primary molecules forming concrete. Epoxy is often used to bond a stretchy supportive fabric or a thin plate made of reinforced polymer composites to concrete structures in order to increase the strength and durability of the structure. Specifically, they are interested in how this interface changes when it gets wet. The researchers hope their work will introduce a new paradigm for structural and design engineers to use when predicting the lifespan of building components and large structures. Read a news story.

In papers appearing in Structural Control Health Monitoring (December 2010) and the Journal of Materials Chemistry (April 2011) the researchers describe how a flexible skin-like fabric with electrical properties could be adhered to areas of structures where cracks are likely to appear, such as the underside of a bridge, and detect cracks when they occur. Installing this “sensing skin” would be as simple as gluing it to the surface of a structure in the length and width required. Read a news release.

When graduate student Steve Cranford, a native of Newfoundland, Canada, arrived at MIT in 2008, he brought with him a love of hockey. After attending a few Boston Bruins games, he switched his allegiance from the Canadian Canucks, becoming a loyal fan of his new hometown team. Last week, as he waited for Game 5 of the championship match between the Bruins and the Canucks to begin, he integrated that newfound love for the Bruins with his enthusiasm for research, creating a computer model of the team’s logo made from graphene, the recently discovered form of carbon with a honeycomb geometry a single atom thick.

It might not seem like scraping the top of a cold stick of butter with a knife could be a scientific test, but Professors Franz Ulm and Pedro Reis and graduate student Ange-Therese Akono say the process is very similar to the “scratch test,” which is perhaps the oldest known way to assess a material’s hardness and strength. Using butter as a launching point, they found that the scratch test is actually measuring a material’s toughness rather than its strength. Read a news release.

In an analysis published in Physical Review Letters, researchers led by Professor Ruben Juanes show that the injection of a thin or low-viscosity fluid into a much more viscous fluid (think of water spurting into molasses) will cause the two fluids to mix very quickly via a physical process known as viscous fingering. The thinner liquid will form fingers as it enters the thicker liquid, and those fingers will form other fingers, and so on until the two liquids have mixed uniformly. For maximum mixing to occur quickly, the ideal ratio of the viscosity of any two fluids depends on the speed at which the thinner liquid is injected into the thicker one. Read a news story.

During Campus Preview Weekend, Professor Franz Ulm participated in a Professor Talent Show hosted by SaveTFP, a student group that facilitates all-inclusive student social activities. Ulm's talk focused on the mechanics of scraping the top of a cold stick of butter. After defining the problem mathematically, he stated that it takes a bit less force (he's always really tired in the morning, he says) to scrape a narrow, deep strip of butter than a wider, shallow one. He went on to show how the mechanics of this problem relate to the nation's energy reserves and ended by warning the students that if they want to get famous, they should not become engineers. "Engineers only get famous when things go wrong," he said to laughter. View the video (5:50 to 19:15).

Professor Roman Stocker wrote an invited news commentary that accompanied an article in the Feb. 2 Early Edition of the Proceedings of the National Academy of Sciences about a newly discovered mechanism of locomotion used by marine microbes. In his commentary, "Reverse and flick: Hybrid locomotion in bacteria," Stocker writes: "Our understanding of bacterial locomotion has long been driven and biased by the wealth of knowledge on E.coli," which has four to eight flagella, each "powered by a reversible rotary motor. When all motors spin counterclockwise, hydrodynamic interactions cause the flagella to form a bundle that propels E. coli forward in a nearly straight 'run.' When one or more motors switch direction, the bundle comes apart, causing a change in direction." But many marine microbes have only a single flagellum, so how do they change direction? Xie et. al. describe a means for these cells to change direction by reversing, then using a flick of the flagellum to propel in a different direction.

Senior Research Associate (retired) Carl Martland, has a new book out titled, "Toward More Sustainable Infrastructure: Project Evaluation for Planners and Engineers" (Wiley 2011). Based on a subject he developed and taught at MIT (1.011 Project Evaluation), the book prepares readers to "evaluate projects based on an appreciation of the needs of society, the potential for sustainable development and recognition of the problems that may result from poorly conceived or poorly implemented projects and programs." Martland, a railroad transportation specialist, was quoted in an article appearing in the Boston Globe Feb. 14 about the new CSX railyard in Worcester, which uses cranes to lift and move cargo containers between railcars and trucks, rather than the older, less efficient forklift-like sideloaders.

Course 1 senior Kallie Hedberg and junior Julia Hopkins are co-authors of a paper that appeared in a March issue of the American Journal of Disaster Medicine. "Vaccine Availability in the United States during the 2009 H1N1 Outbreak" was written by Hedberg, Hopkins, Professor Richard Larson of the Engineering Systems Divison (ESD) and co-authors. Larson said the 1C students "worked tirelessly" with the Centers for Disease Control-supported ESD Flu Team, performed the majority of the research that led to the paper, and did much of the writing. The paper "details statistically the supply-chain mishaps in production and delivery of the H1N1 flu vaccine … is already leading to two follow-on papers … and an improved set of policies for vaccine distribution. We believe the paper demonstrates how an MIT engineering approach can add value in areas not traditional to engineering," said Larson.

Efforts to prevent or reverse eutrophication in freshwater typically aim to decrease the amount of phosphate entering the lake or river in runoff from the watershed. But a new study by Professor Harry Hemond and Katherine Lin ’05 (who performed the research as a UROP student) suggests that phosphate control measures that simultaneously decrease nitrate inflow could, paradoxically, result in an increased release of phosphate from lake sediments that have become enriched after years of heavy phosphate inflow. Incorporating this information into engineering models of lake eutrophication could make them more accurate and useful. Read a news story.

In an opinion piece in Technology Review, Professor Eduardo Kausel writes about the engineering and planning aspects of rebuilding that will be required in the wake of the earthquake and tsunami that hit Japan March 11. "Given the huge and tragic loss of life that has resulted, no compassionate human being could possibly wish last week’s devastating earthquake and subsequent tsunami on any country. But if it had to happen – and it is an inescapable geological fact that earthquakes do have to happen – there are many worse places it could have happened. In a very real sense, Japan was prepared for it and, unlike so many parts of the world hit by devastating earthquakes, it is well-placed to embark on the massive rebuilding exercise that will now ensue."

Committee says DOD should pay some of the costs of transportation infrastructure near U.S. military bases
March 7, 2011
CEE Professor Joseph Sussman recently chaired a congressionally mandated committee that released a report calling for the Pentagon to pay some of the cost of new transportation infrastructure needed to mitigate the relocation of tens of thousands of military personnel later this year, rather than making local and state governments shoulder the entire burden. The Feb. 7 report also states that some of this funding should go towards the creation or enhancement of public transportation and not focus solely on roads and highways, as has been done in the past.

An article in the Feb. 26 Boston Globe focuses on Professor John Ochsendorf and his new book,"Guastavino Vaulting: The Art of Structural Tile" (Princeton Architectural Press, 2010). Architect Rafael Guastavino (1842–1908) and son are famous for their technique of constructing architectural arches and ceilings using thin interlocking tiles. These vaults were used in hundreds of large public projects across the U.S., including the Boston Public Library and New York City's Grand Central Terminal, but the Guastavino name isn't well known by the general public, mainly because the family served as contractor rather than primary architect on these projects. Ochsendorf's book traces the development of the vaulting technique from its origins in Europe though its use in the United States, and includes photographs by Michael Freeman. Ochsendorf is a professor of civil and environmental engineering and architecture. He received a MacArthur Fellowship in 2008.

Adding particles to liquids to make currents visible is a common practice in the study of fluid mechanics, one that was adopted and perfected by artist Paul Matisse in sculptures he calls Kalliroscopes. Matisse’s glass-enclosed liquid sculptures contain an object whose movement through the liquid creates whorls that can be seen only because elongated particles trailing the object align with the direction of the current; light reflects off the particles, making the current visible to the viewer. Professor Roman Stocker and his research team recently demonstrated that this same phenomenon is responsible for the swirling patterns scientists typically see when they agitate a flask containing microbes in water; many microbes are themselves elongated particles that make the whorls visible. More importantly, they say this phenomenon occurs in the ocean when elongated microbes caught in a current align horizontally with the ocean surface, affecting how much light goes into the ocean and how much bounces off as backscatter.

The settling of particulate organic matter in the ocean is the main means of moving carbon from surface waters toward the deep sea. As the particles fall, microbes colonize them and degrade some of the organic carbon, releasing it into the water. Because the particles are composed of 95 percent or more seawater trapped in a porous, gel-like matrix, and the ocean is stratifed by water of different densities, the particles often reach a depth where they approach neutral buoyancy, leaving them stranded in thin layers affecting how much carbon microbes degrade. Professor Roman Stocker and colleagues demonstrated that the retention time in the layers is due to the diffusive exchange of low-density water from the hollows of the particles with heavier ambient water. Using lab experiments based on time-lapse microphotography, they showed that larger aggregates spend more time in thin layers than smaller particles, with a retention time that increases quadratically with particle radius. Read the paper from the Dec. 6 early online edition of the Proceedings of the National Academy of Sciences.
