-------------------------------------------------------------------- COLLOQUIUM OF THE COMPUTATIONAL MATERIALS SCIENCE CENTER AND THE SCHOOL OF PHYSICS, ASTRONOMY AND COMPUTATIONAL SCIENCES (CSI 898-Sec 001) -------------------------------------------------------------------- High Temperature and High Pressure Research with Diamond-Anvil Cell by Synchrotron Light Source Jinfu Shu Geophysical Laboratory,Carnegie Institution of Washington, Washington, DC The steady development of high pressure and high temperature techniques over the last several decades has culminated in a new era of research on materials under extreme conditions. When pressure is increased on the material, interactions among atoms increase substantially because the effective volume occupied by the constituent particles is reduced. Under these conditions, densities of materials can be increased by over an order of magnitude, in many cases causing numerous structural transformations and inducing new physical and chemical phenomena. With recent advances in diamond-cell technology, static pressures of several hundred GPa can be reached routinely in the laboratory. Physical and chemical properties of materials can be determined accurately at ultrahigh pressures and high temperatures. The advances are intimately linked with the evolution of synchrotron facilities, which provide high-brilliance radiation sources for studying a wide range of properties of sample in diamond-cells. Monday, November 7, 2011 4:30 pm Room 301, Research I, Fairfax Campus Refreshments will be served at 4:15 PM. ---------------------------------------------------------------------- Find the schedule at http://cmasc.gmu.edu/seminar/schedule.html
