source:economyMining rare earth has long been considered a dirty business, as it can lead to water and soil pollution, but a new technology developed by Chinese scientists may reverse the trend, offering a greener alternative for the industry.Rare earth elements (REEs), especially heavy REEs, are an essential part of many high-tech devices, from the iPhone to the Tesla electric engine to LED lights. More than 90 percent of the global heavy REE demand is sourced from ion-adsorption deposits, which form within weathering crusts. However, conventional mining applies excessive usage of chemical ag...

source:newswiseNewswise — Researchers from the Department of Energy’s Critical Materials Institute (CMI) and Ames National Laboratory have improved the properties of a rare-earth-free permanent magnet material and demonstrated the process can be upscaled for manufacturing. The researchers developed a new method of manufacturing manganese bismuth (MnBi) magnets based on microstructure engineering. This process is a step towards making compact, energy-efficient motors without the use of rare earths.High-power permanent magnets are increasingly important for a variety of renewable energy technolo...

source:phys.orgA team of researchers at the MPQ has pioneered the integration of erbium atoms with special optical properties into a silicon crystal. The atoms can thus be connected by light at a wavelength that is commonly used in telecommunications. This makes them ideal building blocks for future quantum networks that enable calculations with several quantum computers, as well as the secure exchange of data in a quantum internet. Since the new experimental results were achieved without sophisticated cooling and are based on established methods of semiconductor production, the method appears...
