source:CHEMEUROPE.COMhe quantum-mechanical exchange interaction between electrons, a consequence of the Pauli exclusion principle, can be specifically modified with intense infrared light fields on time scales of a few femtoseconds, as time-resolved experiments on sulfur hexafluoride molecules show. This finding lights a way for bottom-up controlling chemical reactions with lasers in the future – based purely on electrons, the “glue” of chemistry.Electrons form the bonds in molecules and play a decisive role in chemical reactions. In atoms and molecules, the electrons are arranged on a sequenc...

OLPL Materials Help Overcome the Flaws of Traditional Inorganic Long Persistent Luminescence Systems source:AZO MATERIALOrganic long persistent luminescence (OLPL) have great potential for overcoming the defects associated with conventional inorganic long persistent luminescence systems of silicate, aluminate and sulfate-based matrices doped along with rare-earth elements.But the afterglow emission from the majority of the organic materials are thermal activated delayed florescence (TADF) and phosphorescence (Phos), their afterglow durations are generally restricted to seconds level, far ...

Energy Fuels ships uranium, vanadium and REE, performs commercial-scale partial rare earth separation source:MINING.COMEnergy Fuels (TSX: EFR; NYSE: UUUU) made three commercial shipments of uranium, vanadium and rare earth elements (REE) through its Utah-based White Mesa mill last week, a feat which the company described as rare and one that depicts its ability to become a “clean energy and critical mineral hub” in the United States. The company shipped natural uranium concentrates (U3O8) to the Metropolis Works uranium conversion facility in Illinois, vanadium pentoxide (V2O5) to Be...

source:The JAkartaPostThe government has laid out plans to map Indonesia’s rare earth element reserves as part of a wider plan to develop downstream rare earth industries. Energy and Mineral Resources Ministry Mining Director General Ridwan Djamaluddin said on Monday that the ministry had identified eight locations that contained rare earth reserves, with plans to explore more areas up until 2024. “All eight are still in the early exploration stage,” he told House Commission VII, which oversees energy and mineral resources, at a hearing in Jakarta.
