Low-density regions developed in liquefied polyethylene with a point-plane electrode configuration under high electric fields have been investigated using a Schlieren technique in the temperature range from 120 to 200°C. This region, having a refractive index or a density lower than the surrounding medium, is always f…
The crystallization behavior of an Li 2 O‐Zn0‐SiO 2 glass with a ZnO content of −28.5 wt% and nucleated with P 2 O 5 was investigated by infrared spectroscopy, X‐ray diffraction, and scanning electron microscopy. A three‐stage process, consisting of the nucleation, crystallization, and transformation of Li 3 Zn 0.5 Si…

A whole-rod test was conducted at 229 °C to investigate the long-term stability of light water reactor spent fuel rods with artificially induced defects stored in inert and unlimited air atmospheres. Both boiling water reactor (BWR) and pressurized water reactor (PWR) rods were tested. After 2235 h, visual observation…

Randomly cross-linked networks have a complex topology. The determination of their cross-link density is still a challenge since no definitive relationships have been established between Mc, the molecular weight between junctions, and macroscopic characteristics such as the modulus or volume fraction of polymer presen…
Abstract The chemical dehydrochlorination of poly(vinyl chloride) was studied in solution in tetrahydrofuran. Two materials, a mass polymer of 55% syndiotacticity and a low temperature polymer of 63% syndiotacticity, were dehydrochlorinated with potassium hydroxide and with potassium tert ‐butoxide. The dehydrochlorin…
Silicone rubber miniprostheses were coated with solid collagen formed from a fibrillar collagen suspension (Zyderm collagen implant) and then implanted subcutaneously in rats. There was a reduced amount of capsule formation around the coated prostheses, whereas the uncoated control implants all became surrounded by no…
Airborne dust from the production of silicon carbide has been analyzed for particle morphology and composition. Fibers of alpha silicon carbide were identified by scanning electron microscopy (SEM) combined with energy dispersive X-ray spectrometry (EDS) and transmission electron microscopy (TEM) with selected area el…
The purpose of this study was to measure and describe the physical properties of a recently-developed thermodynamic Nitinol alloy, type A-138, at intervals of temperature between room and body temperatures. The properties of stiffness, flexure yield strength and permanent deformation were measured, demonstrating that…
Synopsis A new device using a torsional technique has been developed to record the biomechanical properties of the skin. After determination of the optimal experimental conditions, effects of cosmetic products on the stratum corneum biomechanical properties are described.
Abstract A program of simultaneous linear equations has been developed to calculate component proportions and/or component property values for mineral mixtures in soil clays and sediments. The analysis is based on quantitatively measured chemical and physical properties of samples and involves (1) qualitative identifi…
An accurate electron energy loss formula, modified from that of F. Rohrlich and B.C. Carls (1954), is presented which is useful in the energy range from a few tens of electron volts to 10 keV. Higher order z 3 corrections, which are similar to those for heavy charged particles, and z 2 corrections, defined as deviatio…
Abstract The effect of fiber structure and morphology on the resultant mechanical and low load deformation properties of thermally bonded nonwoven polypropylene fabrics has been studied. Commercially available staple polypropylene fibers varying in linear density and draw ratio (Herculon and Marvess staple fibers) wer…
Four‐point flexure tests were performed at 1100° to 1350°C on two hot‐pressed silicon nitrides, one in which the grain‐boundary phase was amorphous and one in which it was largely crystalline. Fracture stress and relative K 1c were plotted vs temperature. Fracture regions were analyzed by scanning and transmission ele…
The morphology, crystallography, and chemistry of phases present in an as-cast commercial aluminium bronze containing iron, of nominal composition (wt-%) Cu–10Al–2·5Fe (BS 1400: AB1), and the development of microstructure on cooling from elevated temperatures, have been studied using optical and electron microscopic t…
Abstract The reaction of poly(vinylidene fluoride) with several different bases in dimethylformamide solution yields dehydrofluorinated products with conjugated polyene structures. The extent of elimination can be controlled by varying the amount of added base. The structural properties of dehydrofluorinated materials…
Novel procedures were developed to determine the composition of magnesian calcite overgrowths precipitated on calcite crystals from seawater solutions. A surface sensitive analytical technique, Scanning Auger Microanalysis (SAM), was used to determine the composition of very thin overgrowths (< 0.5 ..mu..m) which coul…
