The effect of substitutional and interstitial atoms on the absorption of high energy electrons is considered. Two mechanisms of absorption are discussed; viz. the contributions due to scattering by the additional scattering centres and due to displacements of the atoms surrounding the point defects. The absorption est…
Thermal expansion, temperature change of electrical resistance and its change due to hydrostatic pressure, and magnetic susceptibility were measured with some antiferromagnetic Fe-Mn alloys containing 30 to 40 at% Mn. It was found that an additional magnetic volume expansivity, δ V / V , due to an antiferromagnetic sp…
1. The rubber particles in Hevea brasiliensis latex have been partially purified by ;washing' with buffer solution, and separated into active fractions of different particle size. 2. The enzyme responsible for incorporating isopentenyl pyrophosphate into rubber is distributed between the surface of the rubber particle…
Transmission electron microscope observations of damage in zirconium irradiated with krypton ions are reported. Dislocation loops were observed in irradiated and annealed specimens. These loops were interstitial in nature, fault free and were oriented near primary and secondary prism planes. The Burgers vectors were o…
The variation of refractive index of vitreous silica with purely hydrostatic pressure to 7 kbars was determined from the shift of the localized interference fringes across the specimen kept in an optical pressure bomb. Allowance for the change in the thickness of the specimen was made with the help of Murnaghan's fini…

Abstract Ozone attack on cellulose and related substances was investigated and appears to involve a twofold mechanism. One is a free‐radical chain mechanism involving oxygen in the propagating step. This slow reaction is highly indiscriminate, showing very little, if any, specificity as to the site of attack and resul…
Abstract In a continuously evacuated system in which volatile products are passing from a heated sample to the cold surface of a trap some distance away, a small pressure will develop which varies with the rate of volatilization of the sample. If this pressure (measured by Pirani gage) is recorded as the sample temper…

Abstract The ESR spectra of microcrystalline cellulose and purified cotton cellulose reacted with ceric ammonium nitrate in nitric acid were determined. The effects of the concentration of ceric ion, atmosphere, temperature, and graft copolymerization with acrylonitrile on the rates of formation and decay of radicals…
Abstract Free radicals formed by γ‐irradiation of oriented samples of poly(ethylene terephthalate) (PET) were studied at 25°C. by ESR spectroscopy. The G value for trapped free radicals is 0.02. The predominant radical is identified as $\text{O} - \text{\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle\cdot}$}}{C}…

A previous study of intercrystalline links in polyethylene, carried out using fractionated polymer only, has now been extended to mixtures of fractions and to whole polymer. There is little difference between links grown from concentrated (50%) solutions of polyethylene in n-C32H66, regardless of the molecular weight…

Abstract Leucine transaminase was purified extensively from pig heart muscle. It appeared to be nearly homogeneous by the criteria of both starch gel and free boundary electrophoresis and ultracentrifugation. The molecular weight was found to be 75,000. Purified leucine transaminase is yellow, and our best preparation…
