Schematic showing the arrangement of a 50 µm SnO2 pellet within the diamond anvil cell. XRD is collected axially through the diamonds, while the use of Be as a gasket material permits radial XAS measurements. Left: the sample is placed directly onto the diamond anvil and loaded in a Ne PTM for room-temperature compression. Right: the sample is thermally isolated (Salamat et al., 2014) from the diamond by a thin KBr window, and loaded in Ar for laser-heating experiments. |
