Study: Recycled Lithium Batteries as Good as Newly Mined

IEEE Spectrum: Lithium-ion batteries, with their use of riskily mined metals, tarnish the green image of EVs. Recycling to recover those valuable metals would minimize the social and environmental impact of mining, keep millions of tons of batteries from landfills, and…

Removing the flaws from 3D printing metal alloys

Materials Today: In the past few decades, metal 3D printing has spearheaded efforts to create custom parts with intricate shapes and high functionality. But as additive manufacturers have utilized more metal alloys for their 3D printing needs, so they have faced…

A Novel Solution To Plastic Pollution

Forbes: In the previous article, I outlined the growing global problem of plastic pollution. Global treaties and new technologies that address the manufacture, use, and reuse of plastics are needed to tackle this problem. Some companies are already working on the problem. Researchers have tried several different reuse approaches…

Stacking order in a 2D magnet produces Dirac magnons

Physics World: Three years ago, an international team of researchers observed something unexpected in a sample of chromium triiodide (CrI3): quasiparticles known as magnons appeared to be travelling along its edges, rather than moving through the sample’s bulk. This observation suggested…
