source:live scienceResearchers have discovered a way to purify rare-earth minerals from discarded gadgets with a chemical compound normally used in medicine. They claim their method offers multiple benefits for the environment.Rare-earth minerals, also known as rare-earth metals or rare-earth elements (REEs), include materials such as europium, yttrium, and samarium and have multiple uses in electronics. They are commonly found in smartphones, computers, TV screens and even electric car batteries.Despite their name, REEs are actually quite common but only occur naturally in low concentrations ...

source: Tokyo Institute of TechnologyImagine a thin film, just nanometers thick, that could store gigabytes of data—enough for movies, video games, and videos. This is the exciting potential of ferroelectric materials for memory storage. These materials have a unique arrangement of ions, resulting in two distinct polarization states analogous to 0 and 1 in binary code, which can be used for digital memory storage.These states are stable, meaning they can 'remember' data without power, and can be switched efficiently by applying a small electric field. This property makes them extremely...

Surface oxygen functionality controls selective transport of metal ions through graphene oxide membranessource: Pacific Northwest National LaboratoryDeveloping efficient, selective, and scalable separations for critical materials, including lithium and magnesium, is essential to meeting the increasing demands for clean energy technologies and alleviating challenges with domestic supply chains. Graphene oxide (GO) membranes have shown promise for separating ions from mixed solutions based on size.While previous work used GO membranes for size-based separations, UV light reduction expands the po...
