Ultrasonic attenuation in single crystals of aluminum potassium sulfate dodecahydrate and aluminum ammonium sulfate dodecahydrate as a function of frequency and temperature
Because of suggestions that at least some alum crystals may become ferroelectric at low temperatures, and that a ferroelectric crystal would show anomalies in the absorption of sound, the attenuation of 10, 30 and 50 M.c. ...
The entropy and related thermodynamic properties of propionitrile
The purpose of this investigation was the calorimetric determination of the saturated heat capacity and the heats and temperatures of all phase transitions of propionitrile (ethyl cyanide) from about 15°K to room ...
Chemical reactions at high pressures and high temperatures
Two high pressure devices, the opposed anvil and the tetrahedral anvil, have been used for studying chemical reactions at high pressures and high temperatures. The effect of pressure on the thermal decomposition of potassium ...
