Session 3: New frontiers in extreme conditions crystallography

X-ray diffraction measurements at the most extreme conditions of pressure, temperature and strain rate require the development of new static and dynamic methods to drive materials to these conditions, and new diagnostic developments to overcome the challenges associated with short length and time scales and high radiation environments often encountered. The rewards of such studies are also significant; at extreme density it becomes possible to probe a regime where core electrons begin to play a role in bonding, resulting in greater structural complexity and higher uncertainties in first-principles calculations. High strain rates and fast diagnostic time scales enable the exploration of metastability and phase transformation mechanisms and kinetics. This session seeks to present the most recent developments in extreme conditions drivers and probes, and new discoveries made possible by these developments.
