Newswise — As demand for energy-intensive computing grows, researchers at the Department of Energy’s Oak Ridge National Laboratory have developed a new technique that lets scientists see — in unprecedented detail — how interfaces move in promising materials for computing and other applications. The method, now available to users at the Center for Nanophase Materials…
Newswise — By splitting water molecules, fuel cells can turn electricity into hydrogen fuel. Running in the opposite direction, they consume hydrogen fuel to cleanly power multiple sectors. Typically, heat is a key ingredient for achieving high energy conversion efficiencies that can beat out combustion-based engines. But like a dripping pipe, fuel cells can leak…
Newswise — Near-infrared photodetectors are used in biomedical sensing and defense and security technologies. For enhanced performance and integrated, compact imaging systems, the photodetectors must be able to detect multiple wavelengths of light at once on a single chip. Quantum dots — tiny crystals made of semiconducting material — could present a path forward because…
Newswise — A Korean research team has developed a novel thermoelectric material and generator (TEG) that leverages sponge-like carbon nanotube (CNT) structures, improving the limitations of organic thermoelectric materials while retaining flexibility. The resulting device is expected to be useful in powering small-scale wearable sensors through thermal energy harvesting. Led by Drs. Mijeong Han and…
Newswise — With the increasing demand for underwater and implantable medical electronics, a stable and continuous power supply is essential. However, conventional wireless charging methods (such as electromagnetic induction and radio frequency-based charging) used in smartphones and wireless earphones suffer from short transmission distances, low energy transfer efficiency in biological tissues, and electromagnetic interference. To…
BYLINE: Kalimah Knight Newswise — An $11.5 million sponsorship will launch a new research institute at Tufts focused on materials science and engineering. The Tufts Epsilon Materials Institute is a collaboration between manufacturer Epsilon Group and the university to advance innovations in materials that address global challenges in energy and sustainability. The institute reflects the…
BYLINE: Catie Himes, PNNL Newswise — RICHLAND, Wash.–Chemist Wendy Shaw has been named associate laboratory director of the Physical and Computational Sciences Directorate at the Department of Energy’s Pacific Northwest National Laboratory. In her previous role as PCSD’s chief science and technology officer, Shaw oversaw science and technology strategy and stewarded capability investments. She now helms…
BYLINE: Meghan McDonald Newswise — When Jonaaron Jones started his master’s degree at the University of Tennessee, Knoxville, his mentor invited him to visit the Manufacturing Demonstration Facility, or MDF, at Oak Ridge National Laboratory. “I saw a metal 3D-printed part for the first time,” said Jones. “I knew I was seeing the future —…
Images Newswise — A modified manufacturing process for electric vehicle batteries, developed by University of Michigan engineers, could enable high ranges and fast charging in cold weather, solving problems that are turning potential EV buyers away. “We envision this approach as something that EV battery manufacturers could adopt without major changes to existing factories,”…
Newswise — COLUMBUS, Ohio – A new smart insole system that monitors how people walk in real time could help users improve posture and provide early warnings for conditions from plantar fasciitis to Parkinson’s disease. Constructed using 22 small pressure sensors and fueled by small solar panels on the tops of shoes, the system offers real-time…
