Scientists have taken a large step toward making a fiber-like energy storage device that can be woven into clothing and power wearable medical monitors, communications equipment or other small electronics.
The device is a supercapacitor—a cousin to the battery. This one packs an interconnected network of graphene and carbon nanotubes so tightly that it stores energy comparable to some thin-film lithium batteries—an area where batteries have traditionally held a large advantage.
The product’s developers, engineers and scientists at Nanyang Technological University (NTU) in Singapore, Tsinghua University in China, and Case Western Reserve University in the United States, believe the storage capacity by volume (called volumetric energy density) is the highest reported for carbon-based microscale supercapacitors to date: 6.3 microwatt hours per cubic millimeter.
As engineering major Patrick DelBarba waited to launch his boat for the finals of the nation’s largest collegiate regatta, one question kept crossing his mind: Would he even get to race?
Philadelphia’s recent flooding had contributed to an extremely fast current on the Schuykill River, and as his event at the Dad Vail Regatta approached Saturday, a bracing wind began blowing upstream.
It was “absolute insanity,” DelBarba recalled, describing waves splashing over his head as he approached the starting line. “We were worried that they would cancel our race right then and there.”
Dominique Durand, the Elmer Lincoln Lindseth Professor in Biomedical Engineering, has been named one of the recipients of the university’s Faculty Distinguished Research Awards for his contributions to the field of neural engineering.
The awards, created last year under the direction of Vice President for Research Robert Miller, recognize faculty members for outstanding contributions to knowledge creation, scholarship and/or artistic creativity in their areas of expertise. Awardees are expected to have national and international renown for their scholarly contributions.
On a section of East 84th Street dotted with abandoned buildings and vacant lots, five seniors from a Case Western Reserve University chemical engineering class spent the spring building a community garden they handed over to residents and others this week.
Leafy greens and onion stems rise from dark, rich soil in beds raised and sealed from unhealthy lead in the gravely ground beneath and the chemicals used to pressure-treat the lumber frames.
A rake, left atop one bed, awaits its owner’s return.
”We have something physical to show, something that will live on after we leave,” said Kelley Morris, who graduates from Case Western Reserve with a chemical engineering degree on May 18.
Nicole Seiberlich, assistant professor of biomedical engineering, wants her PhD students to make painful discoveries—to struggle and find answers on their own.
For that—and teaching, listening and counseling them—Seiberlich won the John S. Diekhoff Award for Graduate Student Mentoring this spring.
Case Western Reserve University created the award in 1978 to recognize faculty who are outstanding mentors to graduate students, connect them with experts in their discipline, engage them academically and promote their professional development. Two faculty members are chosen annually for the award.
