Observation of high-temperature superconductivity in compressed sulfur hydrides has generated an irresistible wave of searches for new hydrogen-containing superconductors.
Hydrogen-rich materials can be metallized at much lower pressures due to "chemical pre-compression" and considered as good candidates for high Tc superconductors.
High-pressure synthesis is a powerful method to synthesize novel hydrides because hydrogen becomes extremely reactive [1] to form novel hydrides under high pressure.
We investigate the ZrHn(n=1-6)in a pressure range of 0-300 GPa,using first-principles calculations within density functional theory,showing that the hydrogen content in Zr dramatically increases under
High pressure can efficiently reduce the barrier of a chemical reaction which hardly occurs at atmospheric pressure and induces the formation of a compound with unforeseen properties.
Velocity-weakening fault property produces unstable slips on the fault interfaces.In the framework of rate-and state-dependent friction,velocity weakening is the result of a healing effect at intergra
