Prior to 2007, the highest pressure at which full single-crystal x-ray diffraction data had been collected and refined was 50GPa. However, building on developments at the SRS (Darsbury), we have pushed the use of such techniques first to 100GPa on Diamond [1] and, most recently, to 145 GPa at the ESRF [2]. The use of these techniques has revealed previously unimagined structural complexity in...

6. The Dynamic Diamond Anvil Cell (dDAC): A Novel Device for Studying the Dynamic Properties of Materials at High Pressure

We have developed a unique device, a dynamic diamond anvil cell (dDAC), which repetitively applies a time-dependent load/pressure profile to a sample. We are adapting this device to pulsed synchrotron radiation to time-resolve and take "snapshots" of pressure-induced transitions and phenomena. This capability allows studies of the kinetics of phase transitions and metastable phases at...
