Larger-than-band-gap photovoltages have been observed in both cubic and hexagonal crystals of ZnS with stacking faults. Under monochromatic excitation the photovoltage measured parallel to the $c$ axis shows two sign reversals at about 3300 A and 3500 A and peaks at approximately 3250 A and 3400 A. The position of the…

Abstract The kinetics of the thermal decomposition of the polyester, Laminac 4116, were investigated in air and argon at atmospheric pressure by means of a continuous recording thermobalance and by differential thermal analysis. Samples were heated from ambient temperature to 600°C. at rates of 5°/min. and 15°/min. In…
Abstract A method for obtaining the intrinsic dielectric constant and loss factor of dry cellulose fiber along the fiber axis was developed, and the dielectric properties of viscose rayon, Bemberg (cuprammonium rayon), and cotton sliver were measured over the frequency range from 500 cycles/sec. to 3 Mcycles/sec. and…
In order to determine whether ferromagnetic or antiferromagnetic exchange coupling would result from alloying the rare earth metals with cobalt or iron, a number of melts were made containing these elements. The data on saturation magnetization with composition and on saturation magnetization with temperature obtained…
A theory for the molecular motion in liquids is formulated. It treats the system as a series of molecular shells bound elastically to each other and to a central molecule. The vibrations of this system are analyzed approximately in an effort to find the probability that the central molecule will be left in a hole larg…
An evaporation technique has been developed to allow thin (approx. 200 Å thick) detached single crystal films of gold to be prepared. These films are very coherent and uniform in thickness. Dislocation lines are observed in these films with a density of 1010-1011/cm2 The dielocations may be observed to move inside the…
Elastic and charge-exchange cross sections have been measured in the energy range 4 to 400 ev for Ne+ in A, A+ in Ne, and A+ in A. Charge exchange was observed only for A+ in A. No evidence was found for the existence of the diatomic ion NeA+. Constants for empirical potential functions have been evaluated and the fun…
Abstract Stable, high molecular‐weight polyoxymethylene resins show the room temperature x‐ray crystalline patterns expected from early work on unstable or low molecular weight polyoxymethylene resins. High‐temperature studies show the specific features of this resin to be: (1) disappearance of crystalline peaks at 18…
Abstract Poly(vinyl chloride), polymerized with the use of γ‐radiation, benzoyl peroxide, and 2,2′‐azobis(isobutyroitrile) as initiators, was thermally decomposed in vacuo. The gaseous decomposition products as analyzed by mass spectrometry consist primarily of hydrogen chloride for decomposition temperatures below ap…

Abstract The effects of several-hundred-hour mechanical-mortar dry grinding of halloysite were studied by X-ray diffraction, differential thermal, electron microscopic and other methods and they were compared with those of kaolinite and Kibushiclay. It has been found that there are two sorts of structural change cause…
Abstract Mineralogical, chemical, physical, and morphological data are given for 18 profiles of Red‐Yellow Podzolic soils. These soils represent 3 profiles each of 2 sequences, one derived from acid crystalline rocks and the other from sandstones. Six profiles of Reddish Brown Lateritic soils are included for comparis…

The composition of the vapor above beryllium oxide held in a tungsten Knudsen cell in the range 1900°-2400°K has been determined mass spectrometrically. The vapor consists predominantly of Be and O atoms and (BeO)3 and (BeO)4 molecules. Smaller amounts of the following molecules were detected: O2, BeO, (BeO)2, (BeO)5,…

Abstract The effects of several-hundred-hour mechanical-mortar dry grinding of kaolinite were studied by X-ray, thermal, electron microscopic and other methods. It has been found that there are two sorts of structural change in the process of dry grinding of kaolinite. One is the production of a non-crystalline substa…
