-
Tidskriftsartikel (refereegranskat)abstract
- Following the discovery of stishovite (the highest-pressure polymorph of silica known from natural samples), many attempts have been made to investigate the possible existence of denser phases of silica at higher pressures. Based on the crystal structures

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- In situ x-ray data on molar volumes of periclase and tungsten have been collected over the temperature range from 300 K to melting. We determine the temperature by combining the technique of spectroradiometry try and electrical resistance wire heating. Th

Tidskriftsartikel (refereegranskat)abstract
- We provide experimental evidence concerning the structure and the pressure-temperature stability of a new polymorph of iron with the double hexagonal close-packed (DHCP) structure. This experiment was performed by an in-situ electrical heating of an iron-
