Classical molecular dynamical simulations of high pressure behavior of alpha cristobalite (SiO2)
Static and dynamic high pressure experiments reveal that the behavior of α-cristobalite (SiO 2 ) depends on the rate and the nature of stress loading. To understand this behavior we have carried outExpand

Pressure induced crystallization in amorphous silicon
We have investigated the high pressure behavior of amorphous silicon (a-Si) using x-ray diffraction and Raman scattering techniques. Our experiments show that a-Si undergoes a polyamorphousExpand

Raman and x-ray diffraction investigations on BaMoO(4) under high pressures.
X-ray diffraction and Raman scattering studies on the scheelite structured barium molybdate show that, at ∼5.8 GPa, it undergoes a first order phase transition to the fergusonite structure (I 2/a,Z =Expand

Proton transfer aiding phase transitions in oxalic acid dihydrate under pressure.
Oxalic acid dihydrate, an important molecular solid in crystal chemistry, ecology and physiology, has been studied for nearly 100 years now. The most debated issues regarding its proton dynamics haveExpand

Classical molecular dynamics simulations of behavior of GeO 2 under high pressures and at high temperatures
We have investigated the high-pressure and high-temperature behavior of GeO 2 with the help of extensive molecular dynamics simulations. Our calculations show that α-GeO 2 transforms reversibly to aExpand

Solubility of ThO2 in Gd2Zr2O7 pyrochlore: XRD, SEM and Raman spectroscopic studies
Abstract Solubility of ThO2 in gadolinium zirconate pyrochlore, a potential host for radioactive materials, has been investigated. The phase relations in Gd2−xThxZr2O7+x/2 (0.0 ⩽ x ⩽ 2.0) systemsExpand

Decomposition of lanthanum hafnate at high pressures
establishthat it decomposes into its constituent oxides beyond 18 GPa. These results are supported by our first-principles total energy calculations. Raman scattering results also imply that theExpand

High pressure phase transformations in α-AlPO4: an x-ray diffraction investigation
We have re-investigated the high pressure behaviour of berlinite AlPO4 (α-AlPO4) with x-ray diffraction using a powerful synchrotron x-ray source SPring-8. Our results show that it transforms to aExpand
