Tech Xplore / The hidden carbon footprint of wearable health care
University of Chicago and Cornell University researchers analyzed wearable health care electronics and reported carbon impacts of 1.1–6.1 kg CO2-equivalent per device. With global device consumption projected to rise 42-fold ...
Tech Xplore / Ultrathin polymer layer extends lifespan of anode-free lithium metal batteries
Anode-free lithium metal batteries, which have attracted attention as candidates for electric vehicles, drones, and next-generation high-performance batteries, offer much higher energy density than conventional lithium-ion ...
Tech Xplore / Self-driving cars could prevent over 1 million road injuries across the US by 2035
Autonomous vehicles could dramatically reduce traffic accidents and injuries on U.S. roads. Drawing on historical data and current trends, a recent JAMA Surgery study projected that self-driving cars could prevent more than ...
Tech Xplore / Reinforcement learning accelerates model-free training of optical AI systems
Optical computing has emerged as a powerful approach for high-speed and energy-efficient information processing. Diffractive optical networks, in particular, enable large-scale parallel computation through the use of passive ...
Tech Xplore / On-demand hydrogen fuel production goes dark-mode
Hydrogen, the lightest element on the periodic table, is a master of escaping almost any container it's stored in. Its extremely small size allows it to squeeze through atomic-scale gaps in the storage materials, which is ...
Tech Xplore / Peering inside perovskite: 3D imaging reveals how passivation boosts solar cell efficiency
Perovskite solar cells have garnered widespread attention as a low-cost, high-efficiency alternative to conventional silicon photovoltaics. However, defects in perovskite films impede charge transport, resulting in energy ...
Tech Xplore / Low-cost gelators nearly double the performance of aircraft anti-icing fluids, finds new study
Tiny molecules already used to thicken everyday products like lotions and adhesives may soon help keep aircraft safe in icy conditions. These molecules, known as low-molecular-weight gelators (LMWGs), can self-assemble into ...
Tech Xplore / New robotic skin lets humanoid robots sense pain and react instantly
If you accidentally put your hand on a hot object, you'll naturally pull it away fast, before you have to think about it. This happens thanks to sensory nerves in your skin that send a lightning-fast signal to your spinal ...
Tech Xplore / New AI model accurately grades messy handwritten math answers and explains student errors
A research team affiliated with UNIST has unveiled a novel AI system capable of grading and providing detailed feedback on even the most untidy handwritten math answers—much like a human instructor.
Tech Xplore / New sensor measures strain, strain rate and temperature with single material layer
Researchers from the Institute of Metal Research (IMR) of the Chinese Academy of Sciences have developed an innovative flexible sensor that can simultaneously detect strain, strain rate, and temperature using a single active ...
Tech Xplore / Passengers' brain signals may help self-driving cars make safer choices
Cars from companies like Tesla already promise hands-free driving, but recent crashes show that today's self-driving systems can still struggle in risky, fast-changing situations.
Tech Xplore / New generator uses carbon fiber to turn raindrops into rooftop electricity
A research team affiliated with UNIST has introduced a technology that generates electricity from raindrops striking rooftops, offering a self-powered approach to automated drainage control and flood warning during heavy ...
