Majidi’s team developed a tactile, magnetic skin
Advanced Science News
Advanced Science News featured work led by MechE’s Carmel Majidi has developed a soft, tactile skin made from a novel magnetic composite. Many tactile skins are used to gather information from the environment to carry out tasks; however, they have difficulties sensing large areas as they often require delicate materials and wiring for each sensing node. The new skin developed by Majidi’s team can be placed on different surfaces. When the surface makes contact with another object, the skin’s internal magnetic field will change. The magnetometer, an electric chip embedded in the skin, will measure the change and infer the location and intensity of the contact. In this way, the researchers can increase the size of their sensing area without changing the output interface.
Rubin comments on Carbon Engineering's carbon capture project
U.S. News & World Report
EPP/MechE’s Edward Rubin was quoted by U.S. News about Carbon Engineering’s planned project in Texas. Carbon Engineering is a Canadian startup planning to build a new type of facility that could remove carbon dioxide (CO2) from the air. Instead of following the traditional approach of drawing CO2 from a smokestack, this project promises to capture CO2 directly from the open-air regardless of location and the gas’ concentration. However, outside experts doubt Carbon Engineering can capture CO2 at scale in a cost-effective manner. “In general, air capture and storage on a meaningful scale is a far tougher problem than CO2 capture at power plants and industrial facilities,” says Rubin. “Much harder to find the needle in a haystack that’s 300 times bigger—hence, much more costly.”
Majidi on soft materials for robotics
MechE’s Carmel Majidi was featured in an ASME Essentials story about soft robotics. According to Majidi, recent advances in materials science have pushed the envelope on how robotics can be integrated into the human body and used in medicine. While there are challenges in development, design, and the marketplace, Majidi sees many opportunities and applications of soft materials. “The fact that you can achieve a really rich range of functionalities with materials that are soft and lightweight will continue to excite researchers and industry stakeholders,” he said.

Ed Rubin, CMU identified as world leader in carbon capture and storage research
Science and the Total Environment
In the field of carbon capture and storage (CCS), MechE/EPP’s Ed Rubin is the most productive researcher in the world by a variety of metrics, finds a new study. Rubin has published the most CCS papers, has the most citations, and is the author of the single most-cited CCS study. Also making the Top-10 list of CCS researchers worldwide is EPP’s Haibo Zhai (8th). The work of Rubin, Zhai, and others has made CMU the most productive academic institution doing CCS research in the world. CMU is second only to the U.S. Department of Energy in total CCS research output. Carbon capture and storage (CCS) is a process technology where carbon dioxide is captured from waste streams (or directly from the atmosphere itself) and stored such that it cannot enter the atmosphere to contribute to the greenhouse effect. Experts expect CCS to be a core decarbonization technology for mitigating global climate change.

The CMU team developed an “Autonomous Prospecting and Extraction System” and won the Lightest System Mass award. The students were advised by MechE’s Aaron Johnson and the Robotics Institute’s Heather Jones.
Presto on fireworks pollution
Pittsburgh City Paper
Every Fourth of July, fireworks are set off around the country, and Pittsburgh is no exception. However, with Pittsburgh’s air quality reputation, are fireworks contributing to pollution? MechE’s Albert Presto says yes, as they release fine particulate matter that is linked to asthma and heart attacks, but not at a significant level to cause worry. “The way a firework works, the reason it’s sparkling is that you’re burning something. There’s usually metal in the firework, and that’s what causes the colors, as the metal gets really hot,” said Presto. “So you get a little bit of particulate matter from shooting off fireworks, but it’s not a big concentration change.”
Students win Perryman Family Foundation scholarships
MSE/BME junior Lindsey Helsel and MechE sophomore Nicholas Acuna have been awarded Perryman Family Foundation tuition scholarships for each year of their remaining undergraduate education.

Bergbreiter, Jayan receive DURIP awards
MechE’s Sarah Bergbreiter and B. Reeja Jayan have received Defense University Research Instrumentation Program (DURIP) awards from the U.S. Army. The award supports the purchase of laboratory equipment important for research projects. Bergbreiter’s award will fund the purchase of a sensor to measure forces in small-scale systems, part of a multi-disciplinary project with her Micro Robotics Lab. Jayan’s award will fund the creation of a new piece of equipment specifically to monitor the structural, phase, and chemical transformations in materials in situ. “The tool will tell us dynamic changes that are happening “live” during the field-assisted materials synthesis process, as opposed to just giving us information at the very end,” said Jayan.
MechE’s Aaron Johnson’s course “Robot Design & Experimentation” followed a “Bioinspired Robots” theme in the spring 2019 semester, leading to unique projects that aimed to imitate various abilities and characteristics of animals. One project was a new version of the Rhex robot called T-Rhex, created by Team ScienceParrot. With tapered toes made of microspines, the T-Rhex can grip multiple surfaces and climb slopes up to 55 degrees, as well as hang from a vertical wall. The team continues to work on the project. “Our main target is exploring the space of materials for leg fabrication, such as fiberglass, PLA, urethanes, and maybe metallic glass,” said team member and Ph.D. candidate Catherine Pavlov. “We think there’s a lot of room for improvement in the leg material and geometry.”
Electric cars are becoming increasingly popular these days. For the first three months of 2019, seven of the top-10 best-selling vehicles in the U.S. were either a pickup truck, an SUV, or a jeep. Carmakers predict that in the coming years, Americans will purchase more electric cars, especially electric pickup trucks and SUVs. Now that battery costs have plunged, pickups “should hit primetime over the next couple of years,” said MechE’s Venkat Viswanathan.

The summer internships are extremely competitive and will allow the students to fully realize the best elements of each solution proposed during the make-a-thon in a finished product intended to improve safety of ice hockey athletes.
A battery-powered plane would be quieter, cheaper, and cleaner than the current options. But for it to be feasible, batteries would need to be safer, pack in more energy, and discharge energy more quickly. MechE’s Venkat Viswanathan says that the kind of technological leap needed for an all-electric commercial plane will likely take decades. He adds that the safety challenge may be solved quicker, since researchers are “close to seeing something real [using ceramics] in two or three years.”
Presto on steel factory’s fire and pollution
In December 2018, a fire broke out at a steel factory in Clairton, resulting in pollution alerts going out to nearby communities. Pollution is already a significant problem in the area, with air quality regularly falling below EPA safety standards and asthma rates rising to nearly three times the national average. “That area is one of the areas with the highest air pollution in the entire country,” says MechE’s Albert Presto, an atmospheric pollution expert. “This fire has contributed to it being even worse.”
In a Quartz article, MechE’s Venkat Viswanathan discussed the discrepancy between the large battery size but low range of Audi’s first all-electric car, the new e-tron. The e-tron SUV has a 95 kWh battery but only 204 miles of range, while Tesla’s SUV (Model X) has a 75 kWh battery with 238 miles of range. According to Viswanathan’s calculations, “Something doesn’t add up.” He has made similar calculations for other products, like Tesla’s Semi and Jaguar’s I-Pace. He notes that because the e-tron is Audi’s first electric car, the company may be playing it safe while playing catch up to Tesla, who have had a head start in improving battery efficiency.

Recently she launched two new awards: SMA Fellows and SMA Young Investigator Award.
Rubin on NBC News
EPP/MechE’s Ed Rubin was interviewed by NBC News about fossil fuels, which are constantly in the news, but rarely discussed in their totality. The article explains what fossil fuels are and describes the characteristics of the three types (coal, petroleum, and natural gas), and how they differ from one another. “Fossil fuels currently supply roughly 80 to 85 percent of the world’s energy,” said Rubin. “They are critically important for everything we do and value as individuals and as a society—all of which need a source of energy.” Though they are cheap and have high energy density, fossil fuels are the leading factor contributing to global warming, which has led to calls to end the world’s dependence on them.

The internationally recognized competition challenges Ph.D. students to consolidate their research projects, goals, and ideas in a three-minute oral presentation. The final competition will be help on Tuesday, March 26 in Kresge Theater in CFA at 4:30 p.m.
MechE’s Venkat Viswanathan was quoted in an Axios article about a newly unveiled battery and tech company, GBatteries, and their development of a faster way to charge lithium-ion batteries, which are used in electronic vehicles. Instead of using the traditional constant current, constant voltage (CCCV), their revolutionary method uses high-frequency “pulses” that would allow people to charge their electric cars as quickly as filling a gas tank. GBatteries’ adapter is likely several years away from commercial release and Viswanathan says, “The main question is whether you can do that without degrading the battery pack.”
MechE’s Venkat Viswanathan and Shashank Sripad recently co-authored a story on vehicle electrification in India for The Hindu. The authors note major gains made in Asia toward electrification and especially the benefits offered by two-wheeled electric vehicles. “The electrification success story in India hinges on electrifying two-wheelers, which will require lowering costs of Li-ion batteries, increasing charging speed and improving the charging infrastructure,” they conclude.
According to MechE’s Venkat Viswanathan in Quartz, ultracapacitors probably had little to do with motivating Tesla’s recent move to acquire ultracapacitor manufacturer Maxwell Technologies. The exact motivation behind the decision is still unclear; however, speculation is that Maxwell’s dry electrode technology could increase storage capacity for Tesla batteries or may help cut costs in the manufacturing process.
Saha wins first preliminary round of 3MT

Whitefoot joins group of experts in refuting EPA proposal
MechE/EPP’s Katie Whitefoot recently joined experts from 10 other leading universities and institutions in co-authoring a study challenging the EPA’s 2018 proposal to freeze fuel economy and emissions standards between 2020 and 2025. The authors contend that the decision, which contradicts a report made in 2016 and affirmed by the EPA in 2017, “has fundamental flaws and inconsistences, is at odds with basic economic theory and empirical studies, is misleading, and does not improve estimates of costs and benefits of fuel economy standards beyond those in the 2016 analysis.”
