X-ray analysis of the dibenzyl series IV—detailed structure of stilbene
Abstract A preliminary account of the crystal structure of stilbene in relation to other compounds in the dibenzyl series has already been given in Part III of this work (Robertson, Prasad and Woodward 1936). The general arrangement of the four molecules in the unit cell was deduced from certain absolute intensity mea…

The Dielectric Properties of Insulating Materials
This paper gives a qualitative account of the way in which dielectric constant and absorption data have been interpreted in terms of the physical and chemical structure of materials. The dielectric behavior of materials is determined by the nature of the polarizations which an impressed field induces in them. The vari…
Magnetic Properties of Single Crystals of Silicon Iron
The magnetization curves for the [100], [110] and [111] directions of single crytals of iron containing 3.85 percent silicon were obtained from single crystal specimens cut in the form of hollow parallelograms so that the sides of each specimen were parallel to the tetragonal, digonal or trigonal axes, respectively. T…

Verformbares Titan und Zirkon
Abstract Es werden die chemischen und metallurgischen Bedingungen näher beschrieben, die für die Reduktion des Ti oder Zr aus ihren Halogen‐ oder Sauerstoffverbindungen berücksichtigt werden müssen. Ein Apparat zur Reduktion größerer Mengen des Oxydes rnit Ca wird beschrieben. Das so gewonnene Metal1 ist warm verformb…
Röntgenuntersuchung der System CaOAl2O3 und SrOAl2O3
Abstract Durch Röntgenuntersuchung der Systeme CaAl 2 O 3 und SrOAl 2 O 3 konnte festgestellt werden, daß in jenem System 5 und diesem 4 intermediäre Kristallarten auftreten. Da jedes Strontiumaluminat in einem Calciumaluminat ein Gegenstück hat, sind die Systeme einander weitgehend analog.
Microbiology of Textile Fibres VI. Relative Humidity over Certain Aqueous Solutions of Glycerol at 25° C
A dew point apparatus was devised for measuring the humidity over aqueous solutions of non-volatile substances. Preliminary experiments proved that results obtained with the instrument were reproducible and that it could be used to make dependable measurements of the relative humidity over such solutions in the range…
The effect of pressure and temperature on the occlusion of hydrogen by palladium
The X-ray method has been employed to investigate the occlusion of hydrogen by palladium when the pressure of the hydrogen surrounding the palladium and the temperature of the palladium are varied. Measurements were made of the parameter of palladium at temperatures of 80, 100, 120, 140 and 160° C. when the palladium…

Some factors influencing the resistance of thin metal films
I E N T summary of the early work on thin metallic films, performed prior to 1928, is provided by Bartlett(').The observations varied profoundlyA not only from one worker to another but also in the experiments of the same investigator performed under similar experimental conditions.As a result of these discrepancies,…

Hydration of magnesia in dolomitic hydrated limes and putties
Heat-Qf-solution and ignition-loss methods have been developed for determining the degree of hydration of magnesia in hydrated dolomitic limes and in hydrated dolomitic lime putties. The rate of hydratiQn Qf magnesia in such limes has been studied when the limes were aged as putties at different temperatures, when sub…
The Molecular Structure of P4O6, P4O8, P4O10 and As4O6 by Electron Diffraction
Molecular structures of P4O6 and As4O6 were determined from electron diffraction data. P4O6 was found to have the symmetry of the point group Td with an angle P–O–P of 128.5±1.5°, and a P–O distance of 1.67±0.03A. In this structure the phosphorus oxygen distances and the phosphorus valence angles were preserved with r…
Theoretical Limitations of Cathode-Ray Tubes
The current density in a focused beam of cathode rays is shown to have an upper limit defined by I = I0(Ee/kT+1) sin2φ, where I is the maximum current density obtainable in the focused spot, I0is the current density at the cathode, E is the voltage at the focus relative to the cathode, T is the absolute temperature of…

The Bonding Force of Cellulosic Materials for Water (from Specific Volume and Thermal Data)
An attempt was made in a previously reported research (14) to determine the volumetric contraction occurring in the water adsorbed by cellulosic materials. Apparent density measurements of wood and cellulose containing various amounts of adsorbed water were made in benzene. Benzene causes no swelling of cellulosic mat…
