In order to find the configuration of the metaborate group the crystal structure of potassium metaborate was determined. The crystals are rhombohedral ar = 7.76A, α = 110° 36′ with six molecules KBO2. The density is 2.348. The space group is R3̄c(D3d6). All atoms are lying on twofold axes at positions: ±(u, ½—u, ¼) ↺…
1. A method, due to Poole & Atkins, is described for computing the total available energy at any depth in the sea, in joules or g.-cal. 2. The oxygen production of pure cultures of the diatom Coscinodiscus excentricus Ehr. was measured by the Winkler method after exposure of the diatoms in bottles at known depths…

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…

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…
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…

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…
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.
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 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…

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…
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…
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…
