The diffusion of several solutes in liquid silver and tin is discussed in terms of the fluctuation model, the modified critical fluctuation theory and the ‘hole’ theory of liquid diffusion, assuming the solute as a point charge equal to the difference in the charge of the solute and solvent atoms. The additional coulo…

Abstract A series of polyaryloxysilanes was prepared from aromatic diols and dianilino‐ and diphenoxysilanes. High molecular weight polymers were obtained at temperatures of 200°C. or higher by using melt‐polymerization procedures. The polymers, which combine the structures of silicones and polyaromatics, possessed hi…
Investigations in oxide system based on tellurium oxide resulted in preparation of new compounds of the type B 3 TeO 6 (B 2+ = Mg,Mn,Ni,Cu). Mg 3 TeO 6 and Mn 3 TeO 6 are isostructural, rhombohedral, pseudo-cubic. Ni 3 TeO 6 crystallizes with the ilmenite structure, whereas Cu 3 TeO 6 obviously belongs to the D 3 5 -s…
Temperature dependence of the dielectric constant and the d.c. electrical resistivity of single crystals of NaNO 2 were measured in the vicinity of the ferroelectric Curie point under precise control of temperature. Anomalies in the dielectric constant ε 22 and the resistivity ρ 22 are seen at 163.8°C (the Curie point…
The characteristics of light emission from hydrodynamic cavitation are given. Changes were examined for small variations in water temperature, pressure, and gas content. Using oxygen, nitrogen, and xenon dissolved in water, the shapes, intensities, and pulse height spectra for individual light pulses were determined.…

The magnetic susceptibilities of the compounds [bipy-H2][MnCl5], [phen- H2]-[MnCl5], [MnCl3(H2O)bipy], [MnCl3(H2O)phen], [MnF3(H2O)phen], [MnCl3 trpy], [MnCl4 bipy], [MnCl3 bipy], [MnCl3 phen], and [MnO phen2](ClO4)2,0.5H2O have been determined over the temperature range c. 100-300°K. All compounds appeared to follow…
Magnetic and optical data on single-crystal RbNiF3 are presented. We conclude that this material is ferrimagnetic, rather than antiferromagnetic as previously reported, with a transition temperature of 139°K and a saturation moment of 21 emu/g at 4.2°K. The basal plane is the preferred plane and the out-of-plane aniso…
Impact shear tests of the Kolsky thin-wafer type were used to determine the effects of temperature and strain rate on the critical resolved shear stress for basal slip in zinc single crystals. At high strain rates the flow stress was found to increase linearly with the plastic strain rate and was independent of temper…
The propagation, of a plane electromagnetic wave in a magnetoelectric crystal is described by an eigenvalue equation in which the eigenvalue is the phase velocity of the wave and the eigenvector is the electric-field. The equation is first solved for the special case in which the dielectric tensor is real and diagonal…
The resistance quenched into pure aluminium wires has been measured as a function of quench temperature for four quench speeds, varying by a factor of 200. The resulting data are consistent with the theory of Flynn et al. (1965), which assumes that the vacancy loss during a quench occurs by migration of single vacanci…
The influence of work-function reduction and variation of the incident-beam angle on the secondary-electron yield and secondary-electron energy distribution from the (111) face of Ge have been studied. Reduction of the work function from 4.79 to 2.3 eV by deposition of Na increased the maximum yield from 1.2 to a valu…

A general theory of electron diffraction by crystals is developed. The crystals are assumed to be infinitely extended in two dimensions and finite in the third dimension. For the scattering problem by this structure two-dimensionally expanded forms of GREEN’S function and integral equation are at first derived, and co…

The optical properties of evaporated opaque films of indium, gallium and thallium have been studied in vacuum throughout the wavelength range of the visible spectrum, 0.4-0.65 μm, by a photographic method. This permitted the simultaneous measurement of the optical constants to be made immediately after evaporation. Th…
This paper describes the characteristics and properties of a new insulation system currently used to manufacture high-voltage bushings at voltage ratings of 15 through 69 kV for transformers and switchgear apparatus. The system is compared with other forms of insulation such as phenolic-paper, oil-paper, mineral-fille…
Larsenite is a rare mineral reported from Franklin, New Jersey. It is orthorhombic with a = 8.244 Å, b = 18.963 Å, c = 5.06 Å, Z = 8, space group Pna 2 1 , and is piezoelectric. The structure was determined using three-dimensional diffractometer data and was refined by least squares to an R of 0.055 for all reflection…
