The extent to which the photoelectronic properties of amorphous chalcogenides can be influenced by specific chemical dopants is a key issue in the study of this technologically important class of semiconductors. The elemental nature and ambipolarity of a-Se make it a particularly attractive candidate for study. The ef…

Abstract An empirical pressure–volume–temperature (PVT) equation of state is presented for polymers in the liquid state, i.e., above the melting point of a crystalline polymer or the glass transition of an amorphous polymer. In terms of reduced variables, the equation is given by \documentclass{article}\pagestyle{empt…
An experimental study of electrostatic electron lenses as a function of geometrical and electrical parameters is described. The lenses are of the symmetrical three-electrode unipotential type. The parameters are the thickness of the center electrode and the interelectrode spacing, both relative to the center electrode…
We present the sequence of full-length chicken triosephosphate isomerase (D-glyceraldehyde 3-phosphate ketol-isomerase, EC 5.3.1.1) mRNA based on the analysis of cDNA and genomic clones. To isolate cDNA clones encoding the enzyme, we screened a muscle cDNA library with radioactively labeled cDNA made from RNA that had…
A computer program to calculate the contributions of crystal, capillary and a simple model of mother liquor to the overall absorption of X-rays has been written. It is based on the Gaussian quadrature method of integration; the crystal is described by the polyhedral faces bounding it, the capillary by its diameter, th…
Abstract— The binding of hematoporphyrin derivated (Hpd) to lipid vesicles and bacterial membranes was determined by fluorescence spectroscopy. The fluorescence measurements of Hpd in aqueous solutions showed two bands at 613 and 677 nm. In lipid environments of lecithin vesicles the fluorescence spectrum was shifted…
A new lyginopterid pollen organ is described based upon specimens occurring in a single coal ball from the Providence, Kentucky locality. Seven to nine beaked sporangia are fused together at their proximal ends forming a common synangial chamber; synangia are joined together in clusters of two or three. In situ prepol…

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…
