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 ...

source:Phys.orgSunlight, one of the planet's most abundant sources of renewable energy, could be used to power lasers, according to a study from Heriot-Watt University.A sunlight-powered laser could be used instead of fossil fuels to kickstart chemical processes for the energy-intensive production of fertilizer, the scientists say.Conventional lasers are powered by electrical energy from a battery or the grid. Even if renewable generation electricity is used, this requires additional infrastructure and energy is invariably lost along the way.Dr. Erik Gauger from Heriot-Watt's Institute...

source:MirageLithium-ion batteries are relatively safe, long-lasting, fast charging and better for the environment than non-rechargeable batteries-right? Not quite. The rocking-chair mechanism that allows for commercial power storage generally uses rare earth elements, such as nickel and cobalt.Researchers have long been on the hunt for alternative batteries that boast all the benefits of lithium-ion versions but include ecological and economic advantages.Now, a team from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS), is closing in on ...
