source:eurekalertRecycling facilities collect glass and mercury from thrown away fluorescent bulbs, but discarded lighting could also supply rare-earth metals for reuse. The 17 metals referred to as rare earths aren’t all widely available and aren’t easily extracted with existing recycling methods. Now, researchers have found a simpler way to collect slightly magnetic particles that contain rare-earth metals from spent fluorescent bulbs. The team describes its proof-of-concept magnetized chromatography method in ACS Sustainable Chemistry & Engineering. Many modern technologies, such a...

source；Phys.orgSkoltech researchers and their colleagues from MIPT and China's Center for High Pressure Science and Technology Advanced Research have computationally explored the stability of the bizarre compounds of hydrogen, lanthanum, and magnesium that exist at very high pressures. In addition to matching the various three-element combinations to the conditions at which they are stable, the team discovered five completely new compounds of hydrogen and either magnesium or lanthanum only.Published in Materials Today Physics, the study is part of the ongoing search for room-temperature su...
