In: AMERICAN MINERALOGIST. - : MINERALOGICAL SOC AMER. ; 81:5-6
-
Other publication (other academic/artistic)abstract
- A molecular dynamics study with analytical and ab initio interatomic potentials revealed the possibility of a new silica phase with Pnc2 structure, which is more stable than stishovite and its CaCl2-like modification at pressures above approximately 120 G

-
Journal article (other academic/artistic)abstract
- Properties and a phase diagram of silica were examined in a broad pressure-temperature range using lattice and molecular dynamics methods and a previously developed interatomic potential (Belonozhko and Dubrovinsky, 1995). Good agreement was reached betwe

Stability of perovskite (MgSiO3) in the Earth's mantle
- 1996
-
In: SCIENCE. - 0036-8075. ; 274:5291, s. 1357-1359
-
Journal article (peer-reviewed)abstract
- Available thermodynamic data and seismic models favor perovskite (MgSiO3) as the stable phase in the mantle. MgSiO3 was heated at temperatures from 1900 to 3200 kelvin with a Nd-YAG laser in diamond-anvil cells to study the phase relations at pressures fr

Journal article (other academic/artistic)abstract
- X-ray synchrotron study of iron heated between 1400 to 2200 K over a pressure range of 40 to 60 gigapascals confirms previous reports of the transformation of the hexagonal closest packed (HCP) phase of iron (epsilon) to the double HCP Iron (beta). The st
