source:techxploreRare earth elements (REE), a group of 17 metallic elements, are in nearly every piece of technology, including cell phones, televisions, computers and almost every part of a vehicle. The demand for these elements increases annually, however the supply is limited geopolitically and is mined with environmentally unsustainable practices.Young-Shin Jun, professor of energy, environmental & chemical engineering in the McKelvey School of Engineering at Washington University in St. Louis, and her team have created a proof-of-concept solution: extracting REEs from coal fly ash, a ...

source:astrobiologyA new biosensor engineered by Penn State researchers offers scientists the first dynamic glimpses of manganese, an elusive metal ion that is essential for life.The researchers engineered the sensor from a natural protein called lanmodulin, which binds rare earth elements with high selectivity and was discovered 5 years ago by some of the Penn State researchers involved in the present study.They were able to genetically reprogram the protein to favor manganese over other common transition metals like iron and copper, which defies the trends observed with most transition metal...

source:news.cornellA model system created by stacking a pair of monolayer semiconductors is giving physicists a simpler way to study confounding quantum behavior, from heavy fermions to exotic quantum phase transitions.The group’s paper, “Gate-Tunable Heavy Fermions in a Moiré Kondo Lattice,” published March 15 in Nature. The lead author is postdoctoral fellow Wenjin Zhao in the Kavli Institute at Cornell.The project was led by Kin Fai Mak, professor of physics in the College of Arts and Sciences, and Jie Shan, professor of applied and engineering physics in Cornell Engineering and in A&a...
