source：Chemical&Engineering Newsare-earth metals are essential parts of electronic components in phones, vehicles, displays, and wind turbines. A new study shows that a recently discovered protein from bacteria outperforms many current methods for extracting these elements from waste streams while potentially being more environmentally friendly (Inorg. Chem. 2020, DOI: 10.1021/acs.inorgchem.0c01303).Concentrated amounts of rare-earth metals, also called lanthanides, are only found in a few ore deposits around the world. More abundant but far more dilute sources of these materials include e...

source:Eurek AlartElectricity and magnetism have been unified by Maxwell's equations, which is the foundation of a vast amount of modern technologies. Nevertheless, achieving efficient coupling of electric and magnetic properties in solid materials has always been challenging throughout the century. This mainly results from that the magnetic and electric properties originate from, respectively, the spin and orbital dynamics of the electron. With these two dynamics being relatively independent from each other, the magneto-electric coupling is hardly observed in most materials, and the elect...
