Pronounced interplay between intrinsic phase-coexistence and octahedral tilt magnitude in hole-doped lanthanum cuprates source:natureAbstractDefinitive understanding of superconductivity and its interplay with structural symmetry in the hole-doped lanthanum cuprates remains elusive. The suppression of superconductivity around 1/8th doping maintains particular focus, often attributed to charge-density waves (CDWs) ordering in the low-temperature tetragonal (LTT) phase. Central to many investigations into this interplay is the thesis that La1.875Ba0.125CuO4 and particularly La1.675Eu0.2Sr0....

source:recyclingtodayThe Remade Institute, a public-private partnership established by the U.S/ Department of Energy (DOE), has announced a new technology license involving an innovation that enables easier and more cost-effective precious metals recovery from end-of-life electronics.Developed with support from West Henrietta, New York-based Remade, the technology is part of a research and development project it first funded in 2020. The project, “Low-Concentration Metal Recovery from Complex Streams Using Gas-Assisted Microflow Solvent Extraction (GAME),” is in progress and is led by Wencai Z...

source:eurekalertMicrolasers with multiple lasing bands are crucial components in various applications, such as full-color display, optical communications, and computing. Rare earth (RE) elements offer abundant long-lived intermediate energy levels and intraconfigurational transitions necessary for emissions over a wide range of lightwave bands.It’s possible to generate deep-ultraviolet to mid-infrared light by pumping photons through lasing processes known as “downshifting,” to lower the frequency — and 'upconversion,' to increase the energy. Upconversion offers unique advantages, inc...
