Rare-earth magnet recycling tech wins innovation award

By Laura Millsaps, Ames Laboratory Communications

An acid-free dissolution rare-earth magnet recycling process has earned a 2018 Notable Technology Development Award from the Federal Laboratories Consortium (FLC). Researchers at the Critical Materials Institute (CMI) and Ames Laboratory invented a magnet recycling process in which magnets are dissolved in water-based solutions, recovering more than 99 percent purity rare earth elements. Cobalt is…

Engineers studying nanodefects suspected of causing early failures of electrical materials

By Mike Krapfl, Iowa State University News Service

Breakdowns in electrical materials can lead to short circuits and blown fuses, robbing the power grid and even cell phones of reliability and efficiency. Iowa State University’s Xiaoli Tan, professor of materials science and engineering, is working to be the first to see and record how nanoscale defects in electrical insulators may evolve into material breakdowns….
