Diamond-anvil cell

Since its invention around 1960, the Diamond-Anvil Cell (DAC) has been adapted to a lot of different applications. Our lab has played a major role in developing different styles of DAC for various experimental techniques since the early 1960s. Taking X-ray diffraction as an example, the DAC has been adapted for powder diffraction, single crystal diffraction and cross-axial geometry. In the last decade, we have used synchrotron radiation as the intense X-ray source to study equations of states and the kinetics of phase transformation and reactions of silicates, oxides and metals at high pressure and temperature in real-time. The latest DAC development in this lab is the Hydrothermal Diamond-Anvil Cell (HDAC).
