High-pressure stable phases in mercury azide
WebThree new phases with P-1, P2 1 /m, and P-1 structures at pressures of 38 GPa, 125 GPa, and 148 GPa are identified for the first time. The theoretical calculations show that the two P-1 structures are dynamically stable at 50 GPa and 200 GPa. WebInvented by Torricelli used to measure atmospheric pressure.

WebApr 4, 2024 · In Cmm 2-ZnN 5 and Pcc 2-ZnN 6, nitrogen atoms polymerize into three-dimensional network structures and network layers under high pressures. Those predicted structures may enrich the phase diagram of high-pressure zinc nitrides, and provide clues for synthesis and exploration of novel stable polymeric nitrogen.
WebWith increasing pressures, the monoclinic angle increases in Phase III and then becomes stable in Phase IV. The bulk moduli of Phases II, III, IV, and V are determined to be 18 ± 4, 20 ± 1, 27 ± 1 and 34 ± 1 GPa, respectively. The ionic character of alkali azides is found to play a key role in their pressure-induced phase transitions.
