Penn State Engineers Are Developing An Inexpensive, Thermally-Modulated Battery For Electric Cars
schwit1 shares a report from Penn State University: Range anxiety, the fear of running out of power before being able to recharge an electric vehicle, may be a thing of the past, according to a team of Penn State engineers who are looking at lithium iron phosphate batteries that have a range of 250 miles with the ability to charge in…
Atomic-Scale Nanowires Can Now Be Produced At Scale
fahrbot-bot shares a report from Phys.Org: Researchers from Tokyo Metropolitan University have discovered a way to make self-assembled nanowires of transition metal chalcogenides at scale using chemical vapor deposition. By changing the substrate where the wires form, they can tune how these wires are arranged, from aligned configurations of atomically thin sheets to random networks of bundles. This paves the way…
