Catalytic processes and in particular heterogeneous catalysis are vital for todays industry. However, many industrial catalytic processes require high temperatures and pressures to work efficiently. This stands in contrast to biological catalysts, which fu ...
Using X-ray diffraction with synchrotron radiation, we have studied the pressure changes induced by laser heating on samples compressed in a diamond-anvil cell. The method has been to compare experimentally observed phase transitions of Mg2SiO4 and SiO2 po ...
Raman spectra of Y2O3 single crystal were recorded at room temperature in a diamond anvil cell up to a pressure of 22 GPa. Two phase transitions were detected at pressures of 12 and 19 GPa. The different phases were identified with the three structures exh ...
Raman spectra of hexagonal close-packed iron (epsilon-Fe) have been measured from 15 to 152 gigapascals by using diamond-anvil cells with ultrapure synthetic diamond anvils. The results give a Gruneisen parameter gamma(o) = 1.68 (+/-0.20) and q = 0.7 (+/-0 ...
The Raman spectrum of calcium aluminate (CaAl2O4) glass has been obtained as a function of pressure at ambient temperature to similar to 15 GPa, and as a function of temperature at room pressure to 1650 K. On increasing pressure at 300 K, the Raman spectru ...
We report a precise determination of the Z0-B̄0 mixing parameter Δmd based on the time evolution of same-sign and opposite-sign dilepton yields in Y(45) decays. Data were collected with the Belle detector at KEKB. Using data samples of 29.4 fb-1 recorded a ...
We report the results of a low-temperature (300 K-15 K) high-pressure (up to 22 GPa) Raman study of the Verwey transition in magnetite (Fe3O4). We use additional Raman modes observed below the Verwey transition to determine how the transition temperature c ...
Thermomechanical modeling of a sample assembly (sample plus pressure transmitting medium) in a laser-heated diamond-anvil cell (LHDAC) is presented. Finite elements numerical calculation afforded to obtain the temperature distribution and the induced therm ...
Raman spectra of Mg2GeO4-olivine were obtained from ambient pressure up to 34 GPa at ambient temperature. Under quasi-hydrostatic pressure conditions, the following modifications in the Raman spectra occur as pressure increases: 1) near 11 GPa, two sharp e ...
Nucleation has been studied on atomic scale for Ag deposition on a Pt(111) surface at low temperature (50-120 K) by means of variable-temperature scanning tunneling microscopy. From island density versus coverage data, the transition from the initial steps ...
