source:physResearchers at Berkeley Lab's Accelerator Technology & Applied Physics (ATAP) Division have developed a method for detecting and predicting the local loss of superconductivity in large-scale magnets that are capable of generating high magnetic fields. These high-field magnets are a core enabling technology for many areas of scientific research, medicine, and energy, where they are used in a range of applications, including in particle accelerators and colliders for high-energy and nuclear physics, diagnostic and therapeutic medical devices, and energy generation, transmissio...

source:newscenterRare earth elements (REEs) like lanthanum and neodymium are essential components of modern electronics, from cell phones and solar panels to satellites and electric vehicles. These heavy metals occur all around us, albeit in tiny quantities. But demand continues to rise and because they occur in such low concentrations, traditional methods of extracting REEs can be inefficient, environmentally polluting, and detrimental to the health of workers. Now, with funding from the Defense Advanced Research Projects Agency (DARPA) Environmental Microbes as a BioEngineering Resource...

Influence of deformation banding instabilities on small scale yielding of a Mg–Nd alloy revealed by in-situ digital image correlation source:natureAbstractPropagating deformation bands are observed to accommodate the initial plasticity in an as-extruded Mg–1.5Nd alloy under tension using digital-image-correlation. The propagating bands cause an uncommon plateau in the stress–strain response of the alloy prior to restoring a common decreasing work hardening with further straining. Effects of the deformation banding and underlying plateau in the flow stress on small scale yielding are inves...

source:miningweeklyThe information derived from a study published on the mineralogy and distribution of rare-earth elements in the high-ash coals of South Africa’s Waterberg coalfield could assist with a new concept of logging coal seams.This logging, as reported by Mining Weekly last year, takes into account the rare earth elemental composition of coal, rather than only thermal coal’s energy characteristics related to its use in power generation.This potentially far-reaching study was conducted by the Clean Coal Technology research group at the University of the Witwatersrand (Wits), in Johan...
