Abstract The smectite to illite reaction was studied by transmission and analytical electron microscopy (TEM/AEM) in argillaceous sediments from depths of 1750, 2450, and 5500 m in a Gulf Coast well. Smectite was texturally characterized as having wavy 10- to 13-Å layers with a high density of edge-dislocations, and i…

The MNDO parameters for sulfur have been reoptimized. Calculations for a number of sulfur compounds indicate a very significant improvement. Inclusion of d AOs failed to correct the errors for compounds of sulfur in its higher valence states. Since d AOs are not included, the calculations are still confined to compoun…

In situ Raman spectroscopy and cyclic voltammetry have been used simultaneously to study anodic film growth and dissolution on Cu and Ag in strongly alkaline solution. On copper, Cu 2 O and another species, believed to be a hydroxide, were detected spectroscopically during anodic film formation. Raman spectra of elect…
Mechanical properties of aluminium polycrystals exhibiting differences in grain boundary (GB) properties have been studied by means of the Hall-Petch analysis. The results obtained indicate that the value of the stress intensity coefficient k depends on the distribution of GB diffusivity. High values of the diffusion…
Abstract Practical problems of the reproduction of the orientation distribution function (ODF) from pole figures (PFs) using discrete methods (with special attention paid to Imhof's method,) are analysed. A new variant of the iteration method for the determination of the ODF in arbitrarily defined size of cells in the…
Abstract Clays can act as osmotic membranes and thus give rise to osmotically induced hydrostatic pressures. The magnitude of generated osmotic pressures in geologic systems is governed by the theoretical osmotic pressure calculated solely from solution properties and by value of the membrane's three phe-nomenological…
Lattice parameter and density data were compiled for Y 2 O 3 ‐Stabilized ZrO 2 , both from the literature and from experimental measurements. The data are described very well over a wide range of composition by the model of Aleksandrov et al. , which assumes Y substitution for Zr in the unit cell with compensating ani…

A low temperature thermal cleaning method for Si molecular beam epitaxy (MBE) is proposed. This method consists of wet chemical treatment to eliminate carbon contaminants on Si substrates, thin oxide film formation to protect the clean Si surface from contamination during processing before MBE growth, and desorption o…
Data on the chemisorption of oxygen on a number of metals (Pt, Pd, Ir, Ru, Ni, etc.), obtained by SED, EAS, XES, etc., have been reviewed. The bond energies and principal properties of the two types of Oads on metals (non-reconstructive and reconstructive), and also the conditions for the realisation of each type of a…
Series solution calculations of cooling rates are applied to a variety of samples with different thermal properties, including an analog of an Apollo 15 green glass and a hypothetical silicate melt. Cooling rates for the well‐studied green glass arid a generalized silicate melt (density = 2.5 g/cm 3 , heat capacity =…
The interest in the subject of ion-containing polymers has continued unabated since the development of organic ion-exchange resins in the 1940's. This interest is due to the variety of properties and applications that result from the interactions of ions bound to organic macromolecules. These interactions affect the p…
The effect of a slowly receding electron on the shape and location of an Auger line is investigated for Auger transitions following photoionisation of an inner-shell electron. The theory of Niehaus and Morgenstern (1977) is reformulated and extended to take into account the time it takes for the fast Auger electron to…
An ionic fluid is modelled as a mixture of dipolar hard spheres (the solvent) and charged hard spheres (the ions). The free energy is expanded in a power series in the inverse temperature. Some of the terms in this expansion are infinite. However, these terms can be resummed to give a finite result. This expansion red…
