source:recyclingtodayThe Remade Institute, a public-private partnership established by the U.S/ Department of Energy (DOE), has announced a new technology license involving an innovation that enables easier and more cost-effective precious metals recovery from end-of-life electronics.Developed with support from West Henrietta, New York-based Remade, the technology is part of a research and development project it first funded in 2020. The project, “Low-Concentration Metal Recovery from Complex Streams Using Gas-Assisted Microflow Solvent Extraction (GAME),” is in progress and is led by Wencai Z...

source:eurekalertMicrolasers with multiple lasing bands are crucial components in various applications, such as full-color display, optical communications, and computing. Rare earth (RE) elements offer abundant long-lived intermediate energy levels and intraconfigurational transitions necessary for emissions over a wide range of lightwave bands.It’s possible to generate deep-ultraviolet to mid-infrared light by pumping photons through lasing processes known as “downshifting,” to lower the frequency — and 'upconversion,' to increase the energy. Upconversion offers unique advantages, inc...

Cage with Caps: Selective confinement of rare-earth-metal hydrates in host molecules Rare-earth metals are indispensable for many technical source:miragenewsRare-earth metals are indispensable for many technical products, from smartphones, laptops, batteries, electromotors, and wind turbines, to catalysts. In the journal Angewandte Chemie, a Japanese team has now introduced a molecular “cage” with “caps” that can be used to selectively “confine” certain rare-earth-metal ions for isolation or recycling. © Wiley-VCH, re-use with credit to ‘Angewandte Chemie’ and a link to the ori...
