The equilibrium segregation A (dissolved) = A (segregated), where A = C, Si, Sn, N, P, O, S … is studied for binary systems Fe-A in the stability range of the α-solid solution using surface-analytical methods. On the surfaces ordered structures were observed by LEED and surface concentrations were determined by AES –…
Abstract The FeCl 3 test is applied to an increasing extent for examining the resistance to pitting and crevice corrosion. Two methods having proved their value are described, the chemical properties of the FeCl 3 solution with regard to hydrolysis, pH and redox potential behaviour at various test temperatures are set…
The electronic and photoelectrochemical properties of the n‐type spinel oxides consisting of Zn‐Ti‐Fe are studied. The composition systems that give the single phase of the spinel structure are and . The conductivities of the former oxides are governed by the hopping mechanism between Fe 2+ and Fe 3+ at the octahedral…
Abstract The southern San Joaquin Valley contains more than 7 km of sedimentary fill, largely Miocene and younger in age. Ancient depositional environments ranged from alluvial fans at the basin margins to turbidite fans toward the basin center. Mixed-layer illite/smectite (I/S) dominates the <2- μ m fraction of Mi…

Stony corals calcify by nucleation and growth of aragonite fibers on seed nuclei packets produced by the coral. Aragonite fibers arrange into polyciystalline bundles that lift the coral upward duringfiber growth, entrapping fibrils and tissue sheets, from the undersurface of the calicoblastic epithelium, between growi…
Abstract A layer-by-layer mechanism explains important features of mixed-layer clay minerals formed during the illitization of smectite, including the occurrence of randomly interstratified illite/smectite, the transition to ordered interstratifications, and the development of long-range ordering. A variety of solid-s…
Abundances have been determined for Li in early F field dwarfs in order to determine the initial Li content for Population I stars. Reticon spectra were obtained at the coudé spectrograph of the CFH telescope of 75 F0 - F5 dwarfs with a spectral resolution of 0.11 Å. High S/N values allowed the observation of weak fea…
Close examination of published measurements of absolute configuration in inorganic crystals has revealed many mistakes, and only a small number of published correlations between optical rotation and chirality of crystal structure can be trusted. The sense of rotation of light is here traced to the hand of specific hel…
Abstract The morphology of illite/smectite (I/S) from deeply buried bentonites and hydrothermally altered Tertiary volcanic rocks from Japan changes in parallel with the proportion of expandable layers in the I/S. As viewed by scanning electron microscopy, the morphologies range from the typical “cornflake,” “maple le…
The electrical conductivities of carbon-black-filled low-density polyethylene (LDPE), poly(methyl methacrylate) (PMMA), and poly(vinyl chloride)-vinyl acetate (PVC/ VAc) copolymer were measured as functions of carbon content and melt viscosity of the matrix at the temperatures at which the composites were prepared. Sh…
Proline is accumulated in Escherichia coli via two active transport systems, proline porter I (PPI) and PPII. In our experiments, PPI was insensitive to catabolite repression and was reduced in activity twofold when bacteria were subjected to amino acid-limited growth. PPII, which has a lower affinity for proline than…

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…
