Dynamic plasticity of beryllium in the inertial fuel fusion capsule regime (2007)
Swift, Damian C., Tierney, Thomas E., Luo, Sheng-Nian, Mulford, Roberta N., Kyrala, George A., Johnson, Randall P., ...
The plastic response of beryllium was investigated during loading by laser-induced shock waves, using surface velocimetry and in-situ x-ray diffraction. Results from loading by thermal x-rays...

We report a novel crystalline carbon-cage structure synthesized from laser-driven shock wave loading of a graphite-copper mixture to about 14±2 GPa and 1000±200 K. Quite unexpectedly, it can be...
Melting at the Limit of Superheating (2004)
Luo, Sheng-Nian, Ahrens, Thomas J., Swift, Damian C.
Theories on superheating-melting mostly involve vibrational and mechanical instabilities, catastrophes of entropy, volume and rigidity, and nucleation-based kinetic models. The maximum achievable...
Luo, Sheng-Nian, Swift, Damian C., Tierney, Thomas, Xia, Kaiwen, Tschauner, Oliver, Asimow, Paul D.
The maximum superheating of a solid prior to melting depends on the effective dimensionless nucleation energy barrier, heterogeneities such as free surfaces and defects, and heating rates....
Luo, Sheng-Nian, Ahrens, Thomas J., Çağin, Tahir, Strachan, Alejandro, Swift, Damian C.
The maximum superheating and undercooling achievable at various heating (or cooling) rates were investigated based on classical nucleation theory and undercooling experiments, molecular dynamics (MD)...
Waveform and differential travel-time (DTT) of various PKP phases have been utilized to study the velocity variations at the core-mantle boundary (CMB) and the inner-core boundary (ICB). The spatial...

Superheating systematics of crystalline solids (2003)
Luo, Sheng-Nian, Ahrens, Thomas J.
Systematics of superheating (theta= T/Tm–1) of crystalline solids as a function of heating rate (Q) are established as beta= A(Q)(theta+ 1)theta2, where the normalized energy barrier for...
