Abstract An aufgedampften amorphen Te‐Schichten wurde die Temperaturabhängigkeit der spezifischen Leitfähigkeit gemessen. Bei hohen Temperaturen (> 200 °K) ist die Eigenleitung mit Δ E ≈ 0,87 eV vorherrschend. Bei tiefen Temperaturen ergibt sich eine Störleitung, die sich durch Erwärmung auf relativ niedrige Temper…
The complete orientation distribution of the a and b crystallographic directions have been measured for a series of tubular extruded polyethylene films as a function of blow ratio. The use of pole figures as a means of representing orientation is emphasized and it is shown that the usual technique of using flat plate…
The phonon spectrum of reactor grade graphite is computed by means of the essentially exact root sampling technique for a sampling 47 788 points in an irreducible segment of the Brillouin zone. Measurements of the specific heat (over the range 100°—1000°K) are used to determine the force constants, resulting in good a…

In a previous paper the present author showed several patterns of imperfect graphite spherulite appearing in nodular iron improperly treated with a cerium containing nodularizing agent, from which concluded that the nodular graphite is nothing but a spherulite consisting of innumerable columnar crystals of graphite gr…

Abstract Polycrystalline NdNbO 4 and GdNbO 4 , isostructural with the monoclinic form of YTaO 4 (Fergusonite), were prepared by the usual ceramic method. GdNbO 4 is paramagnetic with an asymptotic Curie point extrapolated to be 0 °K. NdNbO 4 becomes antiferromagetic at 25 °K. Their room temperature electrical resistiv…
Abstract A pragmatic, easily applied theory of the extended X-ray absorption fine structure found on the high-energy side of absorption edges is developed. This simple model can be successfully applied to determinations of interatomic distances, and it accounts for differences in Kronig structure on different absorpti…
The effect of both compressive and tensile stresses of up to 500lbf/in2 at various temperatures in the range 20–400°C on the power loss, coercive force and remanence of two grades of grain-oriented 3% silicon iron has been measured at 50c/s. Increasing tension at first reduces the power loss and the coercive force, bu…

The absorption spectra for single crystal and polyerystalline UO2 have been measured between 0.6 and 15 μm at room temperature. The spectrum for UO2 resembles that of a typical semiconductor, opaque in the visible but transparent over a large portion of the infrared. An absorption edge is located at approximately 0.6…
Oxygen pressures of the pyrolusite form of MnO 2 have been determined in a temperature range of 441°–642°C. The dissociation reaction 4 MnO 2 ( c ) ⇄ 2 Mn 2 O 3 ( c ) + O 2 ( g ) has been found to reach a steady state in the forward direction; reaction in the reverse direction was exceedingly slow and did not reach a…
