source:.lpi.usraMeteorites and asteroids fascinate planetary scientists because they represent the building blocks of the planets and offer unique insights into the earliest moments of our solar system. Meteorites can be identified as such due to unique chemical signatures, and some types (iron meteorites) show beautiful textures called Widmanstätten patterns, which could only form over millions of years. Moreover, these extraterrestrial materials are important for their potential as in-situ resources for space exploration and industrialization, with the most attention given to water (imp...

source:theswaddleLast month, two teams of scientists — from USA’s Northwestern University and UK’s Cambridge University — came up with methods to synthesize a material that doesn’t exist on Earth. The scientists devised their own methods to create tetrataenite — a complex iron and nickel alloy present exclusively in meteorites landing from outer space. In the long run, this development holds the potential to revolutionize green energy.A vital component of building renewable energy options is permanent magnets. Magnets and magnetic materials’ ability to generate electricity provides a cleaner, ...

source:natureAbstractWe investigated the random lasing process and Replica Symmetry Breaking (RSB) phenomenon in neodymium ions (Nd3+) doped lead-germanate glass–ceramics (GCs) containing MgO. Glass samples were fabricated by conventional melt-quenching technique and the GCs were obtained by carefully devitrifying the parent glasses at 830 °C for different time intervals. The partial crystallization of the parent glasses was verified by X-ray diffraction. Photoluminescence (PL) enhancement of ≈ 500% relative to the parent glasses was observed for samples with a higher crystallinity degree...

source：wyomingnewsA legislative committee advanced a bill that would authorize the state to apply for primacy over federal permitting and licensing that guides the management of rare-earth-element mining’s radioactive byproducts.Lawmakers and industry representatives believe the Wyoming Department of Environmental Quality can permit and oversee the management of rare earth materials containing uranium and thorium more quickly and efficiently than the federal Nuclear Regulatory Commission, which may entice more rare earth mining in the state.“We’re laying the groundwork here to attract these co...
