Grain-size control in situ at high pressures and high temperatures in a diamond-anvil cell

Grain size and grain boundaries are important parameters that should be taken into account in high-pressure diffraction studies. The effects of pressure and temperature on crystal growth in the diamond-anvil cell have been studied using various starting materials.

Facilities for high-pressure research with the diamond anvil cell at GSECARS

Instrumentation for high-pressure research with the diamond anvil cell at GSECARS is described in terms of capabilities and characteristics. Future prospects are discussed with regard to these facilities for high-pressure research.
