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...

source:psu.eduUNIVERSITY PARK, Pa. — What do corncobs and tomato peels have to do with electronics? They both can be used to salvage valuable rare earth elements, like neodymium, from electronic waste. Penn State researchers used micro- and nanoparticles created from the organic materials to capture rare earth elements from aqueous solutions.Their findings, available online now, will also be published in the November issue of Chemical Engineering Journal. “Waste products like corncobs, wood pulp, cotton and tomato peels often end up in landfills or in compost,” said corresponding au...

source:sciencedailyRare earth metals, when linked, can act as a conduit for energy flow, and show promise for the development of novel materials.Scientists have connected two soft crystals and observed energy transfer between them -- a finding that could lead to the development of sophisticated, responsive materials. The study, by scientists at Hokkaido University in Japan, was published in the journal Nature Communications.Soft crystals are flexible molecular solids with highly ordered structures. When they are subjected to external stimuli, such as vapour or rubbing, their molecular structur...
