A New Simple Metal Alloy Found to Be the Toughest Material
December 27, 2022 | Leave a Comment
Open Image…Save ImageOpen Image (using #TmpD/ia)… Lawrence Berkeley National Lab scientists have measured the highest toughness ever recorded of any material. The discovery came while investigating a metallic alloy made of chromium, cobalt, and nickel. Not only is the metal exceptionally strong and ductile, its properties become enhanced as it gets colder. This runs counter to most other materials in […]

Increasing The Fire Safety Level Of Lithium Ion Batteries
December 22, 2022 | Leave a Comment
DOE/SLAC National Accelerator Laboratory researchers reported a polymer-based electrolyte makes for batteries that keep working – and don’t catch fire – when heated to over 140° F. Rechargeable lithium-ion batteries power phones, laptops, other personal electronics and electric cars, and are even used to store energy generated by solar panels. But if the temperature of […]

New World Record Set For Tandem Solar Radiation Cells
December 21, 2022 | Leave a Comment
Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) researchers reported a new world record for tandem solar cells consisting of a silicon bottom cell and a perovskite top cell. The new tandem solar cell converts 32.5 percent of the incident solar radiation into electrical energy. The certifying institute European Solar Test Installation (ESTI) in Italy measured […]
