Non-Cavitational Tensile Creep in Lu-Doped Silicon Nitride

F Lofaj, Sheldon M. Wiederhorn, Gabrielle G. Long, B Hockey, P R. Jemian, L Browder, April Andreas
The tensile creep behavior of a Lu-based silicon nitride, SN 281, was studied in the temperature range 1400 C to 1550 C with test periods of up to 10 000 h. Strain rates were 3 to 5 orders of magnitude less than those for Yb-based grades of silicon nitride

Nonresonant Control of Multimode Molecular Wave Packets at Room Temperature

January 1, 2002

R A. Bartels, T C. Weinacht, S R. Leone, H C. Kapteyn, M M. Murnane
We demonstrate the creation and measurement of shaped multimode vibrational wave packets in CCl 4 for the first time. Impulsive Raman excitation of wave packets allows coherent control techniques to be applied to molecules without passing through an
