Discontinuous Thermal Expansions and Phase Transformations in Crystals at Higher Temperatures
The purpose of this investigation is to make more detailed studies of transformations. Fourteen compounds have been examined by high temperature X-ray diffraction for this purpose. The investigations have been carried out in such a way as to reveal: 1. the existence of transformations, 2. the influence of polarizability on thermal expansion, 3. the anisotropy of expansion, and 4. the discontinuity of thermal expansion.

An Experimental Verification, with Krypton, of the Theory of the Thermal Diffusion Column for Multicomponent Systems
The extended form of the Jones and Furry theory, which describes the behavior of a multicomponent heavy isotopic gas in a Clusius-Dickel thermal diffusion column, is tested. Experimental and theoretical values of the thermal diffusion column transport equation coefficients Hsub{ik},Ksub{c}, and Ksub{d}, are determined for krypton, a heavy isotopic gas with six isotopes. The experiments are carried out in a column of the hotwire type, at three wire temperatures: Tsub{H}=350 degrees C, 500 degrees C and 800 degrees C. Good agreement is found between the theoretical and experimental values of the coefficients. Seven of nine of the experimentally determined values of the coefficients agree within +- 10% with the corressponding theoretical values. The remaining two experimental values agree within +- 20% with the corresponding theoretical values.
