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,…

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…

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…
The mathematical treatment of dipole-dipole coupling in my previous article on magnetism applies with but little modification to the electric case. Because of fluctuation effects, the use of the usual Lorentz local field E+4πP/3 and of the Clausius-Mossotti formula cannot be justified except as a first approximation v…

The system PbO-B20 3, of interest to investigators and manufacturers of ceramic glazes and glasses, was studied by well-known methods involving quenching and petrographic examination.In addition, limits of liquid immiscibility were obtained by direct observation.Seven crystalline forms of binary compounds were found a…
Abstract Die Verbindungen (NH 4 ) 2 SbBr 6 , Rb 2 SbBr 6 und Rb 2 SbCl 6 sind kubisch, flächenzentriert, mit Metallatomen in (8e), Antimonatomen in (4b) und Halogenatomen in (24a) (Bezeichnungen nach WYCKOFF).

Abstract Es wurden die Schmelzdiagramme einer Reihe von Oxyden gemischt mit CeO 2 untersucht. Alle Gemische ergaben nur ein einfaches Zusammenschmelzen bis auf Cr 2 O 3 welches eine Verbindung CeCrO 3 zeigte. Das CeO 2 wurde nur beim Schmelzen in Gemischen mehr oder weniger zu Ce 2 O 3 reduziert, allein erwies es sich…

Investigation of the 3-percent chromic acid anodizing bath showed that the recommended voltage cycle was essential for formation of the best coatings. It was shown that not only could the corrosion-inhibiting properties of the coatings be improved by an increase in concentration of the electrolyte to 5 to 10 percent o…
