Effects of Dry Grinding on Kaolin Minerals. III. Halloysite
Abstract The effects of several-hundred-hour mechanical-mortar dry grinding of halloysite were studied by X-ray diffraction, differential thermal, electron microscopic and other methods and they were compared with those of kaolinite and Kibushiclay. It has been found that there are two sorts of structural change cause…
The Genesis of the Red‐Yellow Podzolic Soils
Abstract Mineralogical, chemical, physical, and morphological data are given for 18 profiles of Red‐Yellow Podzolic soils. These soils represent 3 profiles each of 2 sequences, one derived from acid crystalline rocks and the other from sandstones. Six profiles of Reddish Brown Lateritic soils are included for comparis…

Vaporization of Beryllium Oxide and Its Reaction with Tungsten
The composition of the vapor above beryllium oxide held in a tungsten Knudsen cell in the range 1900°-2400°K has been determined mass spectrometrically. The vapor consists predominantly of Be and O atoms and (BeO)3 and (BeO)4 molecules. Smaller amounts of the following molecules were detected: O2, BeO, (BeO)2, (BeO)5,…

Effects of Dry Grinding on Kaolin Minerals. I. Kaolinite
Abstract The effects of several-hundred-hour mechanical-mortar dry grinding of kaolinite were studied by X-ray, thermal, electron microscopic and other methods. It has been found that there are two sorts of structural change in the process of dry grinding of kaolinite. One is the production of a non-crystalline substa…
Effect of spherulites on the mechanical properties of nylon 66
Abstract The presence of spherulites in nylon 66 increases the yield point and reduces the effects of variations in per cent crystallinity. Decreasing the size of the spherulites through increased nucleation results in a higher flexural modulus and yield point, a lower ultimate elongation, and a loss of ductility. The…
High-temperature X-ray diffractometer
A vacuum furnace designed for use with a commercial diffractometer is described. It uses a high-current heater made from tantalum foil, and allows the full Bragg spectrum to be recorded whilst satisfying the Bragg-Brentano focusing condition. The specimen temperature is uniform and can be measured accurately; the furn…
Kernresonanzabsorption von γ-Strahlung in Ir191
Bei der Emission und Selbstabsorption von weicher γ-Strahlung in Kernen treten bei tiefen Temperaturen in Festkörpern sehr starke Linien mit der natürlichen Linienbreite auf. Diese Linien erscheinen als Folge davon, daß bei tiefen Temperaturen bei einem Teil der Quantenübergänge der γ-Rückstoßimpuls nicht mehr vom ein…

Electron Interaction in Solids. Characteristic Energy Loss Spectrum
The characteristic energy loss spectrum of solids is analyzed with the aid of the dielectric formulation of the many-body problem developed by the authors. It is shown that a measurement of the angular distribution of inelastically scattered fast electrons is a direct measurement of the imaginary part of the inverse d…
Water and ion flow across cellulosic membranes
Abstract The primary objective of this investigation has been to explain why cellulose acetate behaves as a semipermeable membrane in saline water. To explain this phenomenon, two different mechanisms for the transfer to water and ions through cellulose acetate membranes were formulated. Those ions and molecules that…
A Definition of Stable Inelastic Material
Abstract The definitions given previously for work-hardening and perfect plasticity are broadened to cover viscous effects. As before, the system considered is isothermal and includes both the body and the time-dependent set of forces acting upon it. An external agency is supposed to apply an additional set of forces…
THE TRANSPORT OF HEAT BETWEEN DISSIMILAR SOLIDS AT LOW TEMPERATURES
The resistance offered to the flow of heat by the mismatch of the elastic constants at the interface between two materials has been calculated. It is shown that for a perfectly joined interface the heat flow is proportional to the difference of the fourth powers of the temperature on each side of the interface. Deviat…
On the heat capacity of crystalline magnesium oxide
Abstract The heat capacity of single crystals of magnesium oxide has been measured in the temperature range 3 to 270°K with estimated accuracies of ± 0.5% for 10 < T < 20°K and ± 0.2% for T > 20°K. Reliable results were not obtained below 10°K because of desorption of helium exchange gas in the ca…
Electron Scattering Cross Section with Relativistic Correction Based on the Thomas-Fermi Theory
A formula for the total cross section for elastic scattering of fast electrons by a Thomas-Fermi potential, including relativistic effects, is derived from the differential cross section previously obtained.
Domain Structure of WO3Single Crystals
Transparent single crystals of W${\mathrm{O}}_{3}$, in the form of plates as large as 10 mm\ifmmode\times\else\texttimes\fi{}10 mm, have been prepared by a sublimation method. The domain structure of these crystals was investigated from room temperature to 1350\ifmmode^\circ\else\textdegree\fi{}C, and a new and peculi…
