Micropolar Theory, a specialization of the Microcontinuum
Theory advanced by A. C. Eringen in the early 1960ts has been
used successfully in predicting the behavior of materials whose
inner structure is composed of rod-like elements. Liquid crystals
fall into this class of materials and their wide-spread use in
Industry and...
Creep experiments were conducted on copper polycrystals deformed within the five-power-law regime. The dislocation structure of copper, which has not been extensively characterized in the past, consists of less-well-defined subgrain walls of relatively low misorientation, typically between 0.1 and 0.3 deg, with a Frank network of dislocations within the subgrains....
A survey of the methods of purification of KC1, for use in
preparing single crystals by growth from the melt, was made. Two
methods, fractional recrystallization and ion exchange, were used.
The purity of the salt and crystals grown from the same salt were
compared with the findings of other...
Solubility studies on the heavy metal sulfides in liquid hydrogen
sulfide at room temperature were carried out using the isopiestic
method. The results were compared with earlier work and with a
theoretical result based on Raoult's Law. A relative order for the
solubilities of sulfur and the sulfides of tin,...
The investigation
of impurity effects on the properties of alkali
halide crystals has often been difficult because of the variation of procedures used in various experiments.
The purpose of this work is to
develop a self consistent method of measuring the IV dipole polarization properties of single crystals while eliminating...
