Laser-driven shock compression experiments reveal the presence of a phase transition in MgSiO(3) over the pressure-temperature range 300-400 GPa and 10000-16000 K, with a positive Clapeyron slope and a volume change of 6.3 (±2.0) percent. The observations are most readily interpreted as an ...
As mentioned above,PCMscan absorb, store, and release large amounts of latentthermal energyduring phase transitions at their phase change points. Meanwhile, thephase change temperatureis a constant value during phase transition, which allows for the storage of energy and also gives a function stabili...
the nonstoichiometry, δ, was measured as a function of oxygen partial pressure, PO2, at temperatures up to 1200°C by means of the thermogravimetric me... Junichiro,Mizusaki,and,... - 《Journal of Solid State Chemistry》 被引量: 356发表: 1985年 Thermochromic VO2 thin films: solution-base...
(one at a lower temperature). Temperature is not the equivalent of the energy of athermodynamic system; e.g., a burning match is at a much higher temperature than aniceberg, but thetotal heatenergy contained in an iceberg is much greater than the energy contained in a match. Temperature,...
Itetragonal and MnIIFeIIIcubic states, both stable at room temperature. The LT-to-HT phase transition can also be induced by laser irradiation at room temperature within the thermal hysteresis. As shown in Fig.1a, the characteristic colour change occurs at the laser spots, leading to a ...
The infrared lattice bands which correspond to the A2 modes of alpha-quartz, are analyzed by means of the classical oscillator model. The observed dependence of the classical parameters on temperature allows to think that non-linear effects occur by approaching the alpha-->beta phase transition.DOI...
Subsequent exploration established that these phenomena occur only in Pr-containing cobaltites, and that the Pr ions drive the spin-state and metal-insulator transitions through a remarkable mechanism. Specifically, numerous techniques confirm a Pr valence transition, where the typical Pr3+at room temp...
We report on a temperature-induced transition from a conventional semiconductor to a two-dimensional topological insulator investigated by means of magnetotransport experiments on HgTe/CdTe quantum well structures. At low temperatures, we are in the regime of the quantum spin Hall effect and observe ...
Quartz undergoes a phase transition at 573 °C, where the low/α-quartz changes to high/β-quartz which is marked by two percent volume increment due to the difference in the densities of the two phases (Somerton and Boozer, 1960; Somerton, 1992; Schacht, 2004). Experimentally, during the...
