MechE’s Albert Presto was quoted by WESA in an article discussing the impact of less traffic during the COVID-19 pandemic. Presto found that less driving led to decreases in carbon monoxide and nitrogen dioxide emissions, as well as reduced fine particulate matter, small particles that can lead to serious health problems. While this research specifically addresses the effects of life during the pandemic, Presto also says that “this is what a potential future atmosphere could look like” in the Pittsburgh region if half of all vehicles became electric cars.
MechE alum Thomas Healy was featured in a Forbes article about his company, Hyliion, and its place in the “electric-powered big rig revolution.” Named to the Forbes 30 Under 30 list in 2017, Healy, 28, has developed an “e-axle” (electrified axle) powered by lithium batteries, his solution for electrifying long-haul trucks. While other companies are building new trucks from the ground-up, Healy decided to develop technology that could be added to old trucks or incorporated into new ones. “The goal was to be able to allow them to still buy the truck they already know and love and have it with a brand-new power train that will really revolutionize their logistics,” he said.
MechE’s Albert Presto was quoted in WESA on pollution during the coronavirus pandemic. The original research was done by Presto and MechE Head Allen Robinson. In a recent paper, a Carnegie Mellon University research group documented a drop in air pollutants. Their work showed that less driving meant lower concentrations of emissions such as carbon monoxide and nitrogen dioxide. Presto said more surprising was the decrease in fine particulate matter, which are really small particles that can cause big health problems. “That was the same whether we were in a high-traffic place or a low-traffic place,” he said.
Viswanathan quoted on batteries
MechE’s Venkat Viswanathan was quoted in Clean Technica on soft solid electrolytes in batteries. Soft solid electrolytes could protect batteries from dendrite formation, a dangerous lithium spike that can cause the battery to fail. “In 2017, when the conventional wisdom was that you need a hard electrolyte, we proposed that a new dendrite suppression mechanism is possible with a soft solid electrolyte,” Viswanathan said. “It is amazing to find a material realization of this approach with PIM composites.”
Majidi on new biopolymer for soft robots
Chemical & Engineering News

Johnson’s robot design course featured in IEEE Spectrum
MechE’s Aaron Johnson’s Robot Design and Experimentation course was featured in an IEEE Spectrum article highlighting how roboticists (and their robots) have been working from home. After the course turned remote, Johnson expected some of the course teams to drastically alter their projects, but none did. “We managed to keep all of the projects more or less as planned,” said Johnson. “We accomplished this by drop/shipping parts to students, buying some simple tools (soldering irons, etc.), and having me 3D print parts and mail them.”
Dayal, Babaei co-author paper on lipid receptor formation
CEE/MechE’s Kaushik Dayal and MechE’s Mahnoush Babaei co-authored a new study published in the Journal of Mechanics and Physics of Solids. The paper explores how pathogens use clever methods to invade cell membranes—namely, deceiving the membrane into thinking the virus is safe, instigating the formation process of lipid rafts, which are more likely to allow the virus to enter the cell. The study analyzes the physical components of what takes places during ligand-binding; understanding how viruses use lipid rafts could lead to new approaches to treat and prevent viruses, such as SARS-CoV-2, which causes COVID-19. This paper was a collaboration with multiple institutions worldwide, including Pitt’s Swanson School of Engineering.
Taylor featured on nanostructures
MechE’s Rebecca Taylor was featured in multiple sources, including ScienceDaily, Nanowerk, Science Codex, and Azonano, on her research on nanostructures.

Rubin quoted on Pittsburgh emissions
EPP/MechE’s Ed Rubin was quoted in Next Pittsburgh on Pittsburgh emissions. Two of Pittsburghers’ favorite things, beef and beer, are the biggest sources of planet-warming greenhouse gas emissions in the local food system, according to a new study by a team of 19 Carnegie Mellon students. “What we tried to do for the first time is to put together an overall picture to give policymakers an idea of where the biggest impacts are, and where actions to change the system could be beneficial,” says Rubin. “We couldn’t find any other major metropolitan areas that had done something like this.”
Shimada quoted on robots
San Francisco Chronicle
MechE’s Kenji Shimada was quoted in the San Francisco Chronicle about robots. Amid the coronavirus pandemic, researchers are looking into ways robots could be used to lower the risk of transmission. Shimada is working on a mobile robotic arm able to disinfect high-risk areas like hospital rooms using chemicals or ultraviolet light. He envisions a technology able to map a room and track where the machine has cleaned. “Nothing is visible so you need a digital model to keep track of that,” Shimada said of finding and killing the coronavirus and other microscopic threats. He said he plans to begin testing prototypes on campus, but it could be a year or two before an operational version of the machine is ready, underscoring the need to repurpose some technologies for the time being.
MechE Department Head Allen Robinson was appointed a University Professor by Carnegie Mellon University. University Professor is the highest rank faculty can receive.
Shen quoted on metamaterials
MechE’s Sheng Shen’s research on metamaterials was featured on Tech Explorist. Shen and Ph.D. candidate Jiayu Li created a new scale law to describe the thermal emission properties of metamaterials. “At CMU, we are applying this new scale law to design novel metamaterial-based thermal infrared devices for a variety of applications including infrared signature control, infrared sensing, thermal management, and thermal energy conversion,” Shen said.
Majidi quoted on soft robots
MechE’s Carmel Majidi’s research on soft robots was featured on Science Blog and in Unite.AI. Along with collaborators from UCLA, Majidi was able to simulate soft robots with computer models. “Robots made out of hard and inflexible materials are relatively easy to model using existing computer simulation tools,” said Majidi. “Until now, there haven’t been good software tools to simulate robots that are soft and squishy. Our work is one of the first to demonstrate how soft robots can be successfully simulated using the same computer graphics software that has been used to model hair and fabrics in blockbuster films and animated movies.”
Carnegie Mellon team wins top design
MechE’s Kenji Shimada and Erica Martelly’s face mask design, Moldable Masks, were named a top design in America Makes’ “Fit to Face Challenge.“ Fit to Face Challenge participants were tasked with optimizing a face mask’s continuous fit-to-face contact for a wide range of face types. “Judging the Fit to Face Challenge designs was difficult as the submissions were all very good,” said America Makes Technology Director Brandon Ribic, Ph.D. “It was clear that designers spent significant time developing these masks to meet each of the challenge criteria.”

MechE’s Madelynne Long named a CMWA awardee
Carnegie Mellon Women’s Association
MechE student Madelynne Long was named the College of Engineering’s awardee of the Carnegie Mellon Women’s Association’s 2020 scholarship. The CMWA Awards began in 1964 to honor “an outstanding girl at the university.” Over the years, that tradition has grown to recognize an awardee from each of the university’s seven schools and colleges.
LeDuc’s research on microstructures featured
Advanced Science News
An image of MechE’s Philip LeDuc’s research on microstructures was featured in Advanced Science News' “This month in pictures” for April 2020. The image, which is likened to a garden maze, shows a microstructure made by LeDuc and his colleagues. The image was originally featured in issue 16 of Small.
LeDuc receives Lazarus Award
MechE’s Philip LeDuc has recieved the 2020 Barbara Lazarus Award for Graduate Student and Junior Faculty Mentoring. Named after a beloved member of the Carnegie Mellon community, the Barbara Lazarus Award celebrates those who foster an inviting and nurturing environment for graduate students and young faculty at the university. It was first awarded in 2005.
Presto quoted on Pittsburgh air pollution
MechE’s Albert Presto was quoted in the York Dispatch on the decrease in Pittsburgh air pollution after the coronavirus shutdown. Presto said he first noticed an “obvious change” to air quality levels, specifically for particulate matter, after March 13, when Gov. Tom Wolf first ordered a shutdown of all nonessential businesses and closed schools throughout Pennsylvania. With fewer vehicles on the road, scientists have taken note of the almost-overnight effects of lower air pollution. “There's a definite difference,” Presto said of the changes in air quality in March. “It was like a light switch almost.”
Protecting health care workers
Health care workers are particularly vulnerable to exposure to COVID-19 during intubation procedures when patients can expel a broad spray of infectious fluid. Burak Ozdoganlar, the Ver Planck Professor of Mechanical Engineering, and collaborators in the Heritage Valley Health System in Western Pennsylvania have a solution—a clear, acrylic containment box that significantly reduces the risk of spreading the coronavirus.
