Low-temperature olivine rheology at high pressure
San-Carlos olivine rheology was investigated at pressure (P) up to 9 GPa and temperature (T) lower than 890 ◦C. Six powder specimens were cold compressed and sintered into dense and compact materials, then deformed during relaxation experiments carried out at constant pressure and temperature in DIA-type cubic-anvil apparatus. Sample elastic strain was monitored during relaxation by in situ X-r...
متن کاملSolution-based synthesis of GeTe octahedra at low temperature.
GeTe octahedra were prepared by reaction of equimolar amounts of GeCl2·dioxane and Te(SiEt3)2 in oleylamine, whereas a slight excess of the Te precursor yielded GeTe octahedra decorated with elemental Te nanowires, which can be removed by washing with TOP. The mechanism of the GeTe formation is strongly influenced by the solvent. The expected elimination of Et3SiCl (dehalosilylation) only occur...
متن کاملThermal conductivity of solid argon at high pressure and high temperature: a molecular dynamics study.
The thermal conductivity of solid argon at high-pressure (up to 50 GPa) and high-temperature (up to 2000 K) has been calculated by equilibrium molecular dynamics simulations using the Green-Kubo formalism and an exponential-6 interatomic potential. A simple empirical expression is given for its pressure and temperature dependence. The results are compared with predictions based on kinetic theor...
متن کاملac-Calorimetry at High Pressure and Low Temperature
Recent developments of the ac-calorimetric technique adapted for the needs of high pressure experiments are discussed. A semi-quantitative measurement of the specific heat with a Bridgman-type of pressure cell as well as a diamond anvil cell is possible in the temperature range 0.1 K< T < 10 K. The pressure transmitting medium used to ensure good pressure conditions determines to a great extent...
متن کاملThermal Conductivity and Diffusivity. of Climax Stock Quartz Monzonite at High Pressure and Temperature
Measurements of thermal conductivity and thermal diffusivity have been made on two samples of Climax Stock quartz monzonite at pressures between 3 and 50 MPa and temperatures between 300 and 523 K. Following those measurements, the apparatus was calibrated with respect to the thermal conductivity measurement using a reference standard of fused silica. Corrected thermal conductivity of the rock ...
