source:physicsworldI was recently in Newcastle to attend PEMD2022 – the 11th international conference on power electronics, machines and drives. What struck me was not only the huge performance improvements that have been happening in electric motors and generators but just how far we still have to go to make transport fully carbon-free.Global sales of electric cars (including fully battery powered, fuel cell and plug-in hybrids) doubled in 2021 to an all-time high of 6.6 million. They now account for 5–6% of vehicle sales, with more being sold each week than in the whole of 2012, according to...

source:resource-recyclingChemical engineers have successfully scaled up a method for recycling rare earth elements using membrane solvent extraction.Previous work done at the Oak Ridge National Laboratory with Momentum Technologies piloted an industrial-scale process for recycling rare earth elements (REEs) from e-scrap magnets.Now, the technique has been scaled up to achieve high-purity separations, and researcher Ramesh Bhave said the system “is modular and scalable with a small footprint and minimal waste” in a Oak Ridge National Laboratory press release.Bhave previously worked on other rar...

Resource Base (ASX:RBX) sees widespread clay horizons at Mitre Hill as rain pushes drilling backsource:hemarketheraldMineral exploration company Resource Base (RBX) has completed the first round of step out drilling at its Mitre Hill project in Victoria.A total of 125 drill holes were completed for 1348 metres to test the northwest section of the EL007646 tenement, where higher-grade clay hosted rare earth elements were discovered in an earlier round of drilling.Assays are pending, however, geological logging identified visual ferruginous clayey intervals similar to the previous drilling resul...

source:natureAbstractPolaritons enable subwavelength confinement and highly anisotropic flows of light over a wide spectral range, holding the promise for applications in modern nanophotonic and optoelectronic devices. However, to fully realize their practical application potential, facile methods enabling nanoscale active control of polaritons are needed. Here, we introduce a hybrid polaritonic-oxide heterostructure platform consisting of van der Waals crystals, such as hexagonal boron nitride (hBN) or alpha-phase molybdenum trioxide (α-MoO3), transferred on nanoscale oxygen vacancy patterns ...
