Evidence on lattice displacements due to nitrogen platelets in diamond is reviewed. It is shown that interplanar spacings of a diamond containing platelets may differ in either sense from that of pure diamond, depending upon the index of the Bragg reflection. Structures previously proposed for substitutional nitrogen…
The defect structure of monoclinic zirconia was investigated by measuring the oxygen partial pressure dependence of the electrical conductivity and sample weight. Techniques were developed to calculate the degree of nonstoichiometry and the mobility of the charge carriers from electrical and weight change data. ZRO 2…
An investigation has been made of the chemical and mineralogical transformations which have accompanied the weathering of six basic volcanic rocks from eastern New South Wales. Montmorillonite is initially formed from the destruction of the olivine, pyroxene, and plagioclase in the parent rock, but, in the near-surfac…
ABSTRACT The effects of external osmotic pressure on the rates of development and emergence, respiration, and on changes in glycogen, glycerol, and trehalose concentrations have been studied in cysts of Artemia salina. The only measured effect of external osmotic pressures less than 30 atm. on emergence and developmen…

The preparations, colours, lattice constants, experimental and X‐ray densities of fluorite‐type mixed phases between bismuth(III) oxide and the dioxides of U, Th, Ce, and Zr are described. In the systems UO 2 BiO 1.5 , ThO 2 BiO 1.5 and CeO 2 BiO 1.5 , fluorite phases occur from 0 to 100, 60 and 40 mole per cent Bi…

The theory of Aden and Kerker on the scattering of electromagnetic waves from two concentric spheres has been applied to the interaction of light with two-layer metallic colloids. Starting with gold nuclei 59 Å in ``diameter,'' silver layers 5 to 220 Å in thickness have been grown epitaxially. The optical absorption s…
The optical absorption and fluorescence spectra of trivalent thulium in single crystals of yttrium oxide and the absorption spectrum of pure thulium oxide, are investigated. All the 4f12 electronic energy levels except the 1S0 level are identified. The three Slater Fk parameters and the spin—orbit parameter ζ, giving…
Room-temperature microwave ferrimagnetic resonance measurements of the large uniaxial magnetocrystalline anisotropy fields (Han) of two compositional series of hexagonal ferrimagnetic oxides are reported. Han was found to increase rapidly in the Al-substitution series (SrO·xAl2O3·(6−x)Fe2O3) from 19.3 to 53.4 kOe as x…
The Verdet constants of a number of glasses have been measured with the object of studying the Faraday effect in glass. The Verdet constant was measured for three types of glasses: (1) optical glasses, where the Verdet constant correlates well with the reciprocal dispersion; (2) diamagnetic glasses, where glasses whic…

Abstract “Compulsive” exchange takes place between a barium‐soil and magnesium sulphate solution because Ba 2+ ions are removed from solution by precipitation of barium sulphate. This phenomenon provides a basis for the very convenient routine method for cation‐exchange capacity determination in soils described here.…
