- We studied the high-pressure behaviour of RuO2 and compared with that of its analogue SiO2. The high-pressure stability of Pa (3) over bar phase as compared to fluorite (CaF2) phase has been supported through our calculations, which is in full agreement w

Tidskriftsartikel (refereegranskat)abstract
- We investigated the pressure and volume (PV) dependency in eskolaite (Cr2O3) at ambient temperature and pressure up to 32 GPa using powder X-ray diffractometry. The following values were determined in the present study: bulk modulus (K-T), 240(8) GPa (exp

Tidskriftsartikel (refereegranskat)abstract
- We investigated nanocrystalline nickel experimentally (x-ray diffraction) and theoretically (cluster ab initio calculations). No phase transition was observed in nano-nickel. The volume, isothermal bulk modulus and its pressure derivative derived experime
