"High-Pressure Research from Novel Materials Synthesis to Planetary Interiors"

Abstract: Simulating high-pressure and temperature is essential to understand interior processes and properties of planets. It also provides new pathways to explore new materials and novel properties. There are significant advances in static and dynamic compression techniques in recent years. I use a range of high-pressure techniques, including piston-cylinder and multi-anvil devices, diamond cell, traditional gas-gun, and magnetically-driven Z Pulsed Power Facility, to investigate matters under pressures up to 1000 GPa. I will discuss my recent work on mesoporous materials at high pressure, finding new pathways for nano-casting and synthesis of nanocrystals of superherd materials; and on the composition of planetary cores, presenting an integrated approach to experimentally constrain the light elements in the core from geochemical and geophysical data.

Bio: Yingwei Fei received his B. S. from Zhejiang University, China (1982), and Ph.D. from City University of New York (1989). He joined the Geophysical Laboratory of the Carnegie Institution of Washington in 1988, and is now a senior staff scientist at the Institution. He has published over 200 research papers and edited 2 books, spanning from materials sciences to geophysics and planetary science. He was elected as Fellows of MSA (1999), AGU (2010), and Geochemistry Fellow (2013).
