Hydrogen-rich superconductors are promising candidates to achieve room-temperature superconductivity. However, the extreme pressures needed stabilize these structures significantly limit their practical applications. An effective strategy reduce external pressure is add a light element M that binds with H form ${\mathrm{MH}}_{x}$ units, acting as chemical precompressor. We exemplify this idea by performing ab initio calculations of Ac--Be--H phase diagram, proving metallization Ac--H...
Electrides have attracted increasing interest due to their diversely physical properties, including low work function, high catalytic activity, as well potential superconductivity. In this work, using first-principles crystal structure prediction method in combination with calculations, we uncovered seven thermodynamically stable electrides the electron-rich Li-Si system at a pressure range of 25--100 GPa, namely $C2/c\phantom{\rule{4pt}{0ex}}{\mathrm{Li}}_{5}\mathrm{Si},...
H 6 SSb is demonstrated to be a good superconductor stabilized at submegabar pressure with T c of 115 K 40 GPa.
To address the problem that acoustic transfer functions with underwater platforms cannot be measured accurately, this paper presents a method based on phase compensation to improve accuracy of function measurements platforms. The time-domain impulse response signals multiple cycles are first collected and intercepted, then their differences estimated using least-squares method, is used align phases all signals, weighted averaged over cancel out random noise. water pool test proves reduces...
