source:Paul Scherrer InstituteWhen it comes to layered quantum materials, current understanding only scratches the surface; so demonstrates a new study from the Paul Scherrer Institute PSI. Using advanced X-ray spectroscopy at the Swiss Light Source SLS, researchers uncovered magnetic phenomena driven by unexpected interactions between the layers of a kagome ferromagnet made from iron and tin. This discovery challenges assumptions about layered alloys of common metals, providing a starting point for developing new magnetoelectric devices and rare-earth-free motors.The research is published in ...

source:Nature NanotechnologyRare earth elements (REEs), including scandium, yttrium and lanthanides, are strategic resources with unique electric, luminescent and magnetic properties. However, owing to their highly similar physiochemical properties, the identification and separation of all REEs are challenging. Here a Mycobacterium smegmatis porin A nanopore is engineered to contain a nitrilotriacetic acid ligand at its pore constriction. By the further introduction of a secondary ligand Nα,Nα-bis(carboxymethyl)-L-lysine hydrate (ANTA), a dual-ligand sensing strategy was established. A unique ...

source:SMALL CAPSRenegade Exploration (ASX: RNX) has uncovered significant concentrations of critical defence metal antimony along with high-grade gold and silver mineralisation at its Yukon project in central Alaska.The company identified a very large soil anomaly extending over 2 kilometres at the Myschka prospect, with spot high grades of 0.09% antimony, 0.26 grams per tonne gold and 65g/t silver in soil as well as a number of high-grade rock samples.This follows the recent discovery of germanium and gallium concentrations at Renegade’s Andrew zinc-lead-silver deposit, 10 kilometres south o...
