With a phase diagram of more than 15 phases, the structure and properties of H2O ices are fundamental knowledge in condensed matter physics. The student will help PI develop a new resistively-heated diamond anvil cell (RHDAC) for high pressure and temperature elastic properties of high-pressure ice phases. A few candidate heating materials, metallic or ceramic, will be machined by the UROP student using a CNC machine or laser milling machine and will then be tested for performance in a BX90 DAC or typical symmetric DAC in the laboratory. A selected design will be employed in synchrotron experiments on high P-T elasticity of ice phases by single-crystal X-ray diffraction and Brillouin scattering. The PI will provide support for the UROP student to participate in the synchrotron experiments to use the newly developed RHDAC at the Advanced Photon Source, Argonne National Laboratory, if time permits. A successful new RHDAC design and a small set of experimental data using the new DAC can be reported in a peer-reviewed journal.
