The crystal structure of aluminium chloride

J. Α. Α. Ketelaar、C. H. MacGillavry、P. A. Renes1947-01-01Recueil des Travaux Chimiques des Pays-Bas

Abstract Aluminium chloride crystallizes in an ionic layer lattice. The dimensions of the monoclinic cell and the position of the chlorine atoms, given by Ketelaar in a previous investigation, are confirmed. The position of the Al‐atoms is different; instead of the ionic structure described in this paper, Ketelaar fou…

Properties of water-repellent fabrics

John W. Rowen、Davide Gagliardi1947-01-01Journal of research of the National Bureau of Standards

A review and an a nalys is of the t heor y of water repellency of textile fab ri cs have been made. The physicochemical basis underl ying the we ttability, or wa ter repe llency, of t reated fabrics is di sc ussed. A survey of the laborator y test methods for e valuating water repe lle ncy of tex til e fabri cs is pre…

Sur la possibilité d'existence d'un type particulier de radioactivité phénomène de création e

Raymond Daudel、Maurice Jean、Marcel Lecoin1947-01-01Journal de physique

Dans cet article, on montre la possibilité théorique d'existence d'un type nouveau de désintégration β. On étudie, en se plaçant toujours d'un point de vue entièrement théorique, les particularités qui caractériseraient le phénomène.

Stress Induced Preferential Orientation of Pairs of Solute Atoms in Metallic Solid Solution

Clarence Zener1947-01-01Physical Review

In a non-stressed cubic crystal the axes of pairs of adjacent solute atoms are randomly orientated along the several permissible crystallographic directions. It is shown that in the presence of a stress the equilibrium orientation is no longer random, but that certain directions become preferred, and it is further sho…

THE CATALYTIC ACTION OF ALUMINIUM SILICATES: I. THE DEHYDRATION OF BUTANEDIOL-2,3 AND BUTANONE-2 OVER ACTIVATED MORDEN BENTONITE

A. N. Bourns、R. V. V. Nicholls1947-01-01Canadian Journal of Research/Canadian journal of research

The dehydration of butanediol-2,3 over activated Morden bentonite has been investigated. Below 350 °C., liquid products butanone-2, isobutyraldehyde, and the isobutyral of butanediol-2,3 were produced. Butanone-2 was obtained in 86% yield. At higher temperatures, 450° to 700 °C., gaseous decomposition occurred. Only s…

Derivative Crystal Structures

Μ. J. Buerger1947-01-01The Journal of Chemical Physics

There exists a class of crystal structures which are derived from others by generalization. These are here designated derivative structures. A special case of derivative structure is the popular ``superstructure.'' The symmetry of a derivative structure is a subgroup of the symmetry of the basic structure. Here the te…

Absorption of Water by Films of Cellophane and Polyvinyl Alcohol

E. Creutz、Robert R. Wilson1946-12-01The Journal of Chemical Physics

The absorption of water and dehydration of these films is found to obey a diffusion equation by means of which a diffusivity may be defined. This is not a constant but depends on the water concentration in the foils. A rapid change in water content immediately after changing the ambient conditions suggests the presenc…
