High‐temperature deformation of enstatite aggregates

Influence of solute doping on the hightemperature deformation behavior of GaAs

Dynamic compression of enstatite

New shock wave data for Bamle enstatite (Mgo. s•,Feo.•JSiOs in the range from 60480 kb indicate a Hugoniot elastic limit of 67 ñ 10 kb and a possible phase-transition-produced shock front of 135 _ 10 kb amplitude. Above the latter shock pressure, states in a mixedphase regime are achieved up to •350 kb, above which the Hugoniot states are believed to represent the equation of state of a shock-i...

Hydration-Induced Deformation of Lipid Aggregates before and after Polymerization

The dimensions of multibilayer stacks of lipids with terminal diene groups were studied before and after polymerization at variable hydration by means of X-ray diffraction, gravimetry, and infrared spectroscopy. The short-range hydration force acting between the bilayers of lipids with phosphatidylcholine and -ethanolamine headgroups is not affected by lipid polymerization. Consequently, contri...
