source:phyScientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have discovered new details about the electrons in a nickel-based family of superconducting materials. The research, described in two papers published in Physical Review X, reveals that these nickel-based materials have certain similarities with—and key differences from—copper-based superconductors. Comparing the two kinds of 'high-temperature' superconductors may help scientists zero in on key features essential for these materials' remarkable ability to carry electrical current withou...

source:scitechdailyA research team has developed a technique for room-temperature all-solid-state hydride cells, which could enable advanced clean energy storage and conversion technologies. By introducing defects in the lattice structure of rare earth hydrides, the team suppressed electronic conductivity, creating pure hydride ion conductors with high conductivities in a wide temperature range.Materials that can conduct negatively charged hydrogen atoms in ambient conditions would pave the way for advanced clean energy storage and electrochemical conversion technologies.A research team from t...

Investigation of the body-centred tetragonal structure of Fe–Co–V–N Bulk foils using the rolling and ammonia-gas-nitriding method source:natureAbstractImproving the properties of permanent magnets is essential for the advancement of electric motors in reducing energy consumption and carbon emissions. This study investigated the effect of V and N addition to FeCo foils on the stability of tetragonally distorted FeCo-based bulk magnets. The incorporation of these two elements stabilised the body-centred tetragonal structure in thin-film and bulk systems. Fe–Co–V ingots were rolled and nitri...
