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…

The polarized ultraviolet absorption spectra of the tetrahedral CuCl4= ion oriented in single crystals of Cs2CuCl4 and Cs2ZnCl4 have been observed. The spectral bands are identified by means of an analysis which takes into account the observed variations with lattice of the band intensities and positions and which all…
Vapor-pressure and mass-spectrometric measurements on Ti3O5(s) contained in tungsten crucibles show that for the congruent vaporization, Ti3O5(s)=3 TiO(g)+2 O(g),logK=−(1.504±0.011)×(105/T)+39.99±0.59.The vapor-pressure measurements were obtained in the temperature range 1837°—2040°K and are used with auxiliary values…
It is well known that the addition of about 0.2 per cent palladium to titanium significantly increases its resistance to corrosion in non-oxidising acids. It has usually been assumed that the palladium is present as elemental particles at the metal surface and that these function electrochemically to provide anodic pa…

The symbols as used in the text are defined as follows: p — uniform stress on cross sec-tion due to prestress c — distance to the longitudinal crack from the bottom of beam e — distance to the applied force from the bottom of beam P — applied force L — distance from the end of the beam to a cross section where the str…
The dielectric properties of solid solutions in the system SrTiO 3 -La 2/3 TiO 3 were measured in a frequency range from 200 to 10 5 Hz and at temperatures from -190 to 400°C. The relative permittivity of the solid solutions is lower that of pure SrTiO 3 and pronounced dielectric nonlinearity was not observed. Two sep…
Abstract Some features of the linear theory of an elastic Cosserat plate are discussed and special attention is given to a bending theory which corresponds to the bending of a transversely isotropic three-dimensional plate. A useful representation for the solution of the system of differential equations characterizing…
Thin films of vanadium dioxide have been formed by reactive sputtering of vanadium in an argon atmosphere doped with a partial pressure of oxygen. The films were deposited on sapphire substrates held at 400°C and exhibit a highly oriented polycrystalline monoclinic structure at room temperature. The semiconductor to m…
Thermoluminescence emission above room temperature and optical absorption have been studied in LiF crystals irradiated by gamma rays, with emphasis on conditions which are of greatest interest for applications to radiation dosimetry. The specimens were Harshaw crystals of differing purity, and the purpose was to corre…
The role of pH, temperature, salt type, and salt concentration on the three possible transformations involving the crystalline, dispersed helical, and randomly coiled forms of collagen has been investigated. The results are given in terms of pseudo phase diagrams where the field of stability of each form is delimited…
Abstract The kinetics of alkaline degradation of cotton hydrocellulose were determined in 5% NaOH at various temperatures. An activation energy of 24 kcal./mole was found for the endwise degradation reaction, while that of termination to a stable m ‐saccharinic acid endunit is 32 kcal./mole. Consequently, the DP n of…
The fluorescence of Eu3+-activated lanthanide oxyhalides LnOX (Ln=Y, La, Gd, and X=Cl, Br) is reported. Although all host lattices under consideration are isomorphous, the spectral energy distribution of the Eu3+ emission depends strongly on the choice of X and to a lesser extent on that of Ln. This variation is accou…
