Thermal decomposition of ammonium sulphate

W. D. Halstead1970-04-01Journal of Applied Chemistry

Abstract The thermal decomposition and vaporisation of ammonium sulphate, (NH 4 ) 2 SO 4 , is shown to take place via two distinct sets of reactions. In the first, ammonium pyrosulphate, (NH 4 ) 2 S 2 O 7 , is the primary condensed phase product: 2(NH 4 ) 2 SO 4 ← (NH 4 ) 2 S 2 O 7 +2NH 3 +H 2 O The second stage conce…

A multidata method of approximate Laplace transform inversion

Thomas L. Cost、Eric B. Becker1970-04-01International Journal for Numerical Methods in Engineering

Abstract A newly developed numerical Laplace transform inversion technique is described. A derivation of the method, termed the ‘multidata method’, is presented along with a description of a similar collocation method. Similarities and differences between the two numerical methods are described and discussed. Results…

Dislocation Dissociations in hcp Metals

Shahar Mendelson1970-04-01Journal of Applied Physics

Equations are derived for nonplanar dissociations of dislocations in hcp metals. Various components of AB, Aμ, φθ, [AB+φθ], and s′ [AB+φθ] dislocations on the basal, prism, and pyramidal planes meet the criteria for dissociation into twinning partials on{2̄11l} and{1̄01l} planes, and the Burgers vectors of the twinnin…

Porphyrinogens and porphodimethenes, intermediates in the synthesis of meso‐tetraphenylporphins from pyrroles and benzaldehyde

David Dolphin1970-04-01Journal of Heterocyclic Chemistry

Abstract The reaction between pyrroles and benzaldehyde in refluxing acetic acid gives meso ‐tetraphenylporphins and chlorins. The initial condensations give a porphyrinogen which undergoes an acid catalyzed autoxidation to porphyrin via a porphodimethene. The chlorin is shown to be derived from the reduction of porph…

Potassium and Cesium Ion Selectivity in Relation to Clay Mineral Structure

B. L. Sawhney1970-04-01Clays and Clay Minerals

Abstract Selectivity of a number of vermiculites, montmorillonites and micas for K and Cs ions was determined by sorption of these ions from equilibrium solutions of diverse concentrations. The selectivity coefficients were related to the layer charge density and the area of the frayed edges in layer silicates. Montmo…

Raman Scattering in Crystalline Polyethylene

F. J. Boerio、Jack L. Koenig1970-04-01The Journal of Chemical Physics

The Raman scattering in crystalline polyethylene, deuterated polyethylene, and n-paraffins has been investigated as a function of temperature. Crystal-field splitting of the A1G methylene bending mode observed at room temperature increases at − 160°C in both polyethylene and deuterated polyethylene. No splitting of th…

Magnetic Properties of Barium Ferrite Formed by Crystallization of a Glass

Brian Thomas Shirk、W. R. Buessem1970-04-01Journal of the American Ceramic Society

A glass with composition 0.265 B 2 O 3 ‐0.405 BaO‐0.33 Fe 2 O 3 (mole ratio) was prepared by a fast‐quenching technique. When it is heat‐treated, this glass exsolves up to ∼45 wt% BaFe 12 O 19 as the only magnetic phase. Magnetic measurements of glasses heated at various temperatures show that superparamagnetic, singl…

The Nature of Interlayering in Mixed-Layer Illite-Montmorillonites

Robert C. Reynolds、John Hower1970-04-01Clays and Clay Minerals

Abstract The nature of interstratification in mixed-layer illite-montmorillonites has been investigated by comparison of diffraction patterns of ethylene glycol and ethylene glycol monoethyl ether treated samples with calculated one-dimensional diffraction profiles. The calculated profiles take into account the effect…

Catalysis of graphitisation

H. Marsh、A. P. Warburton1970-04-01Journal of Applied Chemistry

Abstract The demand for graphites with specific properties and for an improvement in the economics of graphite production in recent years has led to an increased interest in catalytic graphitisation. At the present time, however, there is no review available of published studies and this paper attempts to make good th…

Amorphous versus Crystalline GeTe Films. III. Electrical Properties and Band Structure

S. K. Bahl、K. L. Chopra1970-04-01Journal of Applied Physics

Various transport studies have been carried out on amorphous and crystalline GeTe films of 80 Å to 10 μ thickness. Crystalline GeTe has a low resistivity (∼10−4 Ω·cm at 300°K) which increases with temperature slowly and nearly linearly at low temperatures (below ∼300°K) and rapidly at higher temperatures. The hole con…

A model for filament growth and switching in amorphous oxide films

G. Dearnaley、D. V. Morgan、A.M. Stoneham1970-04-01OpenAlex

The forming process, by which changes are brought about in the electronic conduction of thin films of various binary amorphous oxides and halides, is first described, and experimental evidence is put forward which contradicts an earlier theory of the forming process in gold-silicon monoxide-metal structures. A theory…

Structure of Finite Nuclei in the Local-Density Approximation

J. W. Negele1970-04-01Physical Review C

A new theory is presented for calculating the structure of finite nuclei from the nucleon-nucleon interaction. The essential features of the reaction matrix in finite nuclei are obtained from nuclear-matter theory through the local-density approximation. The resulting density- and energy-dependent effective interactio…

A new definition for work of adhesion Wa is applied to computationally define the dispersion γs d and polar γs d components of the solid surface tension γs = γs d + γs d for twenty-five low energy substrates. These calculated surface properties are correlated with surface composition and structure. Surface dipole orie…
