source:phys.orgAn Oregon State University researcher who made color history in 2009 with a vivid blue pigment has developed durable, reddish magentas inspired by lunar mineralogy and ancient Egyptian chemistry.Mas Subramanian, distinguished professor of chemistry, and collaborators at OSU report the findings of the study in the journal Chemistry of Materials.The new pigments, which could be used as energy-efficient coatings for vehicles and buildings, are based on divalent chromium, Cr2+, and are the first to use it as a chromophore; chromophores are the parts of a molecule that determine colo...

source:SMALL CAPSVenture Minerals (ASX: VMS) has further confirmed the potential of its large-scale, clay-hosted rare earth elements (REE) Jupiter prospect with further high-grade drilling results at the Brothers project located in the midwest region of Western Australia.Assays from the third and final batch of results from a recently-completed stage one resource definition drill program included a number of the best results seen to date at Jupiter, up to 60 metres at over 2000 parts per million total rare earth oxides (TREO).The receipt of the final stage one assays comes at the same time as ...

source:Phys.orgResearchers at Harvard University, the Lawrence Berkeley National Laboratory, Arizona State University, and other institutes in the United States have recently observed an antiferromagnetic metal phase in electron-doped NdNiO3 a material known to be a non-collinear antiferromagnet (i.e., exhibiting an onset of antiferromagnetic ordering that is concomitant with a transition into an insulating state)."Previous works on the rare-earth nickelates (RNiO3) have found them to host a rather exotic phase of magnetism known as a 'noncollinear antiferromagnet,'" Qi Song,...

source:miningResearchers at CERN’s Neutron Time-of-Flight facility (n_TOF) collaboration are investigating how cerium is produced in stars.Cerium is a rare earth metal that is used in some types of lightbulbs, flat-screen TVs and biomedical applications. While the element is rare in our planet’s crust, it is slightly more abundant in the universe.“The measurement we carried out enabled us to identify nuclear resonances never observed before in the energy range involved in the production of cerium in stars,” Simone Amaducci, first author of the paper that describes the findings, said in a media...
