The electrochemical and corrosion characteristics of Types 383, 304, and 316 stainless steel in 1N¯ H2SO4 were determined using precision potentiostatic polarization and conventional coupon exposure/weight change techniques. Factors increasing the magnitude of the critical anodic current density, Ic, are shown to have…

The thermal coefficients of refractive index have been determined for 23 commercial glasses. The interferometric procedure consisted of determining both the change of optical path of each glass with a change of temperature at a given wavelength and set coefficient of linear thermal expansion of the glass for the same…

The thermal behavior of pyrite in air was studied. A one‐step mechanism for the oxidation of pyrite to hematite exists and accounts for previously reported weight‐loss, DTA, and gas train data which implied a two‐step mechanism. Proper control of the oxidation temperature is very important in completing the pyrite oxi…

In a brief introductory section the derivation of the Shubnikov groups and their importance in the description of the symmetries of magnetic crystals is described. The derivation of the black and white Bravais lattices and of the Shubnikov point groups and space groups is described and there is a brief discussion of s…

The arrangement of the sulfur helices in the pressure-induced fibrous form of sulfur has been determined from three-dimensional x-ray diffractometer data. The crystals show orthorhombic diffraction symmetry, but analysis of their structure has shown that the most probable space group is P2 and that the orthorhombic sy…

A stereographic technique has been developed for the accurate determination of the dimensions of features on scanning electron micrographs. More general methods than those used previously are shown to be necessary largely because of the wide range of operating angles available in the scanning electron microscope. An e…

The ampullate silk gland of the spider, Araneus sericatus, produces the silk fiber for the scaffolding of the web. The fine structure of the various parts of the gland is described. The distal portion of the duct consist of a tube of epithelial cells which appear to secrete a substance which forms the tunica intima of…

The fibrous aluminosilicate imogolite has been studied by electronoptical and infrared absorption methods. Electron diffraction patterns are interpreted in terms of repeat units of 8·4 Å parallel and 23 Å perpendicular to the fibre axis. These spacings can not be reconciled with a continuous silicate chain structure a…

Abstract Fractional crystallization was used to separate a commercial, predominatly isotactice, unstabilized polypropylene into fractions of relatively low and relatively high atacticity, but of similar molecular weight. IR spectroscopy was used to follow the photo‐oxidations of films formed from these fractions durin…

The refractive index nf of evaporated MgF2 films changes almost reversibly with the relative vapor pressure p/po of water in the ambient atmosphere. If q is the porosity, or the fractional volume of the pores in the film, and ns and np are the mean indices of the skeleton of the film and the pore space respectively, i…

Observations of the effect of thermal diffuse scattering, single electron excitations and plasmon excitation on the quality of electron microscope images of crystals are presented and discussed. Preservation of image contrast after thermal diffuse scattering seems to be poor in practice but only a small fraction of th…

Osmotic shock is a procedure in which Gram-negative bacteria are treated as follows. First they are suspended in 0.5 M sucrose containing ethylenediaminetetraacetate. After removal of the sucrose by centrifugation, the pellet of cells is rapidly dispersed in cold, very dilute, MgCl(2). This causes the selective releas…

Magnetoresistance measurements on single-crystal nickel and iron films have been made at temperatures of 4.2 to 295 K in fields of up to 50 kOe. The films were prepared by vacuum deposition onto heated rock salt and mica substrates producing films with (100) and (111) planes respectively, parallel to the film surface.…

Abstract The Raman spectra corresponding to the (bc) component (B2 type vibrations) of the polarizability tensor in the ferroelectric sodium nitrite crystal (C2v20) have been observed with various directions of the phonon propagation. It has been found that one of the B2 Raman lines at 160 cm−1 splits into two compone…

A knowledge of diffusion rates in thin films is often necessary in order to predict the useful operating temperature range of thin film components. The few reported measurements available generally indicate that film diffusion rates at low temperatures (25°–300 °C) are substantially higher than would be inferred from…
