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...

source:Helmholtz Association of German Research CentresThe special properties of rare earth magnetic materials are due to the electrons in the 4f shell. Until now, the magnetic properties of 4f electrons were considered almost impossible to control.Now, a team from HZB, Freie Universität Berlin and other institutions has shown for the first time that laser pulses can influence 4f electrons- and thus change their magnetic properties. The discovery, which was made through experiments at EuXFEL and FLASH, opens up a new way to data storage with rare earth elements.The strongest magnets we kn...
