Kinetics of the reaction of zirconium with pure hydrogen and deuterium was studied for60°–250°C, H 2 pressures of 1.1–5.0 cm Hg, and composition range Zr ‐ ZrH 1.70 , using a vacuum microbalance method. The reaction was shown to be diffusion‐controlled with diffusion occurring from a surface of constant concentration…
1. A preparation of completely haemolysed erythrocytes from the blood ofdomestic fowls, which actively incorporates [Ox-14C]glycine into haem, is described.

Abstract An investigation into the kinetics and the mechanism of thermal and oxidative decomposition of polyvinyl chloride is reported. The rate of HCl evolution was measured in streams of nitrogen, air, and oxygen. The reaction is described as a chain reaction involving initiation (thermal and oxidative), propagation…

A novel method is described for measuring the thickness of a barrier type anodic oxide coating or the barrier layer portion of a porous type anodic oxide coating. This method is used to follow the evolution of the barrier layer during the early stages of the formation of a porous type coating on aluminum and to establ…

The effect of variations in electrolyte and forming conditions on the formation of porous type anodic oxide coatings on aluminum are discussed, with particular reference to the manner in which these variables control oxide formation, pore development, and the thickness of the barrier layer. Formation and solution rate…

Part I of the paper analyses in detail the structure of diamond braid, and its geometry is developed, based on assumptions similar to those of Peirce9. The difficulties of determining braid length which result from its unique structure are considered. In Part II, a practical method of testing tubular braids to find th…

The Hall effect and conductivity of zinc oxide have been measured in dense polycrystalline samples and two single crystals.It has been found that the usual simple Wilson semiconductor model is inadequate for the proper interpretation of results. Several modifications and additions have been suggested for the usual sin…
The structure of titanium monoboride has been determined by single-crystal and powder methods to be of the FeB-type. The dimensions of the orthorhombic unit cell are ao = 6.12, b0 ----3.06 and co -~ 4.56/~. As in other borides of composition MB, the boron atoms form zigzag chains through the lattice. Short interatomic…

The usual theory of thermoelectric power fails to account for the marked rise in this quantity which has been found recently for some semiconductors as the temperature is lowered below room temperature. This paper develops the recently suggested explanation that the thermoelectric power $Q$ is the sum of the usual ele…
