The theory of the kinetics of phase change is developed with the experimentally supported assumptions that the new phase is nucleated by germ nuclei which already exist in the old phase, and whose number can be altered by previous treatment. The density of germ nuclei diminishes through activation of some of them to b…
Abstract 1. Die Hydrosulfide und Hydroselenide von Natrium, Kalium, Rubidium und Cäsium wurden analysenrein dargestellt.
This paper represents the first step in an extended program whose aim is the investigation of solid solutions with special reference to the structures that may be formed by heat treatment and plastic deformation. It is hoped to include eventually observations in high fields (100,000 gauss) and at low temperatures. The…
The problem of the diffraction of x-rays by small crystalline particles is discussed by the methods of Fourier analysis, and the calculation of the intensity of the x-ray scattering from a single particle is reduced to the evaluation of a simple Fourier transform. This approach leads immediately to the interference fu…
Abstract The intensities of the rings formed when a beam of fast electrons is sent through a poly crystalline film were first studied by G. P. Thomson (1929) in the case of thin films of gold. The intensities were found to fit very well (Mott 1929) with those calculated theoretically on the assumption that the Laue th…
Article A Method for the Direct Determination of Crystal Structure from X-ray Data was published on November 1, 1939 in the journal Zeitschrift für Kristallographie - Crystalline Materials (volume 100, issue 1-6).

S ummary Various textile fabrics were exposed to a wide range of climatic conditions. Those exposed to waterlogged conditions were destroyed rapidly. In the case of cellulose fabrics this destruction was due solely to bacteria, and not to fungi or actinomycetes. In the case of wool, the evidence of microbiological act…
The temperature dependence (300\ifmmode^\circ\else\textdegree\fi{}K to 40\ifmmode^\circ\else\textdegree\fi{}K) of the magnetic susceptibility of the following ${\mathrm{Mn}}^{++}$ salts has been measured: MnO, MnS, MnSe, MnTe. A $\ensuremath{\lambda}$-point transition at low temperatures makes the susceptibility break…
Certain properties of clean uranium in vacuum have been investigated. The following values were found: for emissivity below the melting point ($\ensuremath{\lambda}=0.67$\ensuremath{\mu}), 0.51; for thermionic work function, 3.27\ifmmode\pm\else\textpm\fi{}0.05 volts, with a Richardson $A$ of about 6; for melting poin…
The Kozeny equation relating specific surface and permeability of a bed of unconsolidated particles has been shown to be applicable to fibrous materials such as glass, wool, and celanese. The diameters of the constituent fibre may be as small as 0.0006 cm., while their ratio of length to diameter may be indefinitely l…
ABSTRACT Analyses have been made of the body fluids of Echinus esculentus, and two decapod Crustacea, Homarus vulgaris and Cancer pagurus, before and after dialysis with sea water in which they were living. The composition of the perivisceral fluid of Echinus is identical with that of seawater, complete physico-chemic…
The gaseous, liquid, mesomorphous and solid states in monolayers are defined and their close connection with the corresponding states in three dimensions rigorously established. This involves a new treatment of the two-dimensional liquid and of its transformation to the mesomorphous state. The properties of the three-…
