Dielectric and polarization measurements on BaTiO3 at high pressures to the tricritical point.
Dielectric and polarization measurements were made on single crystal BaTi03 in a hydrostatic medium to 38 kbar. The nature of the ferroelectric phase transition is observed to go from first to second order near 35 kbar and —40 C. The pressure —temperature —electric-field phase diagram of BaTi03 is measured. The tricritical point is indicated in this part of the phase diagram by a change in shap...
متن کاملFrench researchers at boiling point
Over 30,000 French scientists have signed an online petition to " save research " set up last month, with a pledge to stop their administrative duties unless the government starts listening to their complaints about funding. There is one signature for every minute that has passed since the petition — aiming to save the French public research base from the latest cuts imposed by the government —...
متن کاملShock temperature measurements in Mg2SiO4 and SiO2 at high pressures
Temperatures in the high pressure shock state have been determined by measurement of optical radiation from pure samples of forsteritc (Mg2 SiOn), a-quartz, and fused silica. Shock waves of known amplitude were produced by tantalum flyer impact using a two-stage light gas gun. Shock pressures in the ranges 150-175 GPa and 70-115 GPa for Mg: SiOn and SiO2 respectively were achieved, and temperat...
متن کاملThermodynamics of Clathrate Hydrate at Low and High Pressures
The thermodynamic stability of clathrate hydrate is calculated under a wide range of temperature and pressure conditions applicable to solar system problems, using a statistical mechanical theory developed by van der Waals and Platteeuw (1959) and existing experimental data on properties of clathrate hydrates and their components. At low pressure, dissociation pressures and partition functions ...
متن کاملThe nematic-isotropic transition at high pressures II : turbidity measurements
2014 Turbidity measurements at high pressures have been performed in the isotropic phases of MBBA, EBBA, and CBNA. In all cases an increase of the value of Tc 2014 T* with pressure is observed. However, rather unusual behavior is found for the magnitude of the turbidity at the isotropic-nematic transition : in MBBA this magnitude decreases with increasing pressure, in the homologous neighbor EB...
