High Pressure

Cheng Ji is a postdoctoral associate at HPCAT. He recieved his Ph.D. in Mechanical Engineering from Texas Tech University. His research interests include phase transitions of materials under large shear stress at high pressures and high pressure related synchrotron x-ray techniques.

High Pressure

Washington, DC— Hydrogen is the most-abundant element in the universe. It’s also the simplest—sporting only a single electron in each atom. But that simplicity is deceptive, because there is still so much we have to learn about hydrogen.

High Pressure, Materials

Ho-kwang Mao's research centers on ultra-high pressure physics, chemistry, material sciences, geophysics, geochemistry and planetary sciences using diamond-anvil cell techniques that he has pioneered. He received a Ph.D. and M.S. from University of Rochester in 1968 and 1966, and a B.S.
