source:PhysicsThe COVID-19 pandemic threw a wrench in supply chains for many materials, including those used to make magnets. Magnets are crucial components in technologies ranging from computer hard-disk drives to magnetic resonance imaging scanners. To circumvent such disruptions, researchers are looking into alternative ways to source magnetic materials. Daniel Casaleiz of IMDEA Nanoscience, Spain, shared the details of one such method at the recent 2022 Joint Magnetism and Magnetic Materials (MMM) - Intermag conference, which took place online and in New Orleans in January.Casaleiz and his...

source:LaserFocusWorld group of researchers at Hokkaido University’s Institute for Chemical Reaction Design and Discovery in Japan combined blue light-emitting diodes (LEDs) with a copper-based molecular catalyst to create a more sustainable way to make chemical subunits (single molecules that assemble with others to form a complex)—with potential applications in pharmaceutical and photoelectronic development.The blue LED and copper-based molecular catalyst combo generates a cross-coupling reaction, in which two molecules are joined via a carbon-carbon bond. It’s a widely used type of rea...

source:Bloomberg GreenAs governments look to secure supplies of crucial rare earth materials, the U.K.’s Pensana Plc signed an agreement with energy company Equinor ASA to look at developing a low-energy method for recycling magnets.The accord is for magnets from wind turbine nacelles -- the central hub that allows it to generate electricity -- to be recycled using hydrogen at Pensana’s hub at the Saltend Chemicals Park. The rare earth company is targeting recycling an annual market of 4,000 tons of end-of-life magnets.Rare earths are crucial to high-tech products from computer hard drives to ...
