Electron Diffraction Studies on Oxide Films formed on Metals and Alloys Part 2 Selective Oxidation of Alloys
Surface oxidation products on various alloys due to varying oxidizing conditions within the range of 300–900°C for temperature and 10 -4 –760 mmHg. for air pressure are studied by the electron diffraction method. Alloys studied are copper alloys containing 0.3 % Be, 0.5 % Al, 0.1 % Mg, 7 % Mn and 7 % Ni and that of ir…

The crystal structure of Mg2(OH)3(Cl,Br).4H2O
The triclinic structure of Mg~(OH)aC1.4H20 has been studied by the method of isomorphous replacement. Atomic positions were derived from a :Fourier (010) projection based on powder data, together with such information as could be gathered from the more or less diffuse (hkl) reflexions.

Kinetics of the Dissolution of Copper in Aqueous Ammonia
Copper reacts readily with aqueous ammonia in the presence of oxygen, as follows: Cu + 1 / 2 O 2 + 4 NH 3 aq + HOH − → Cu NH 3 4 + + + 2 OH − . The kinetics of this reaction were investigated over a wide range of NH 3 and NH 4 + concentrations, oxygen pressures, temperatures, and stirring velocities. The rate of disso…

Relaxation Process in Ferromagnetism
This paper surveys current theoretical work on spin-spin and spin-lattice relaxation in ferromagnetic substances with reference to ferromagnetic resonance. It is shown that it is possible to give a reasonable explanation of the principal features of the experimental results. The calculations, carried out for nickel in…
Anodic Formation of Coatings on Magnesium, Zinc, and Cadmium
A report is given of recent investigations of anodically formed coatings on magnesium, zinc, and cadmium in and solutions. The growth of the coatings was followed by means of x‐ray and electron diffraction and electron microscopy. It was found that the metal oxide was favored as initial product. Depending upon the rel…

Study of the Structure of Quartz, Cristobalite, and Vitreous Silica by Reflection in Infrared
Infrared spectra of α- and β-quartz, α- and β-cristobalite, and vitreous silica were studied by the reflection method using natural and polarized radiation in the 700 to 1400 cm−1 wave number interval. By measuring the reflecting powers at two different angles of incidence, the indices of refraction and extinction wer…
The General Theory of Bolometer Performance
A general phenomenological theory of the static and dynamic behavior of bolometers is presented. The theory assumes as given the fundamental relations between the temperature and resistance of the bolometer, and the past history of the power dissipated within it. From these basic properties are derived a number of the…
Some New Results on Antiferromagnetism and Ferromagnetism
1. The study of the thermomagnetic properties of a natural single crystal of rhomobohedral iron sesquioxide, ${\mathrm{Fe}}_{2}$${\mathrm{O}}_{3}$, by Pauthenet, confirms the hypothesis of the superposition of a fundamental antiferromagnetism and a parasitic ferromagnetism. Below 260\ifmmode^\circ\else\textdegree\fi{}…
Magnetic Spectra of Ferrites
A brief discussion is given of the meaning of initial permeability, the principles of its measurement, and the nature of "dimensional resonance." In considering magnetic spectra containing only a single resonance, typical data on sintered ferrites and on finely divided ferrite powders are reviewed, and some of the the…
Neutron Diffraction Studies of Various Transition Elements
Neutron diffraction measurements are reported on a series of transition elements as an investigation into their magnetic structures. Scattering data have been taken for W, Mo, Nb, V, Cr, Mn, and Fe at various temperatures as low as 4.2\ifmmode^\circ\else\textdegree\fi{}K, and these data are interpreted in terms of the…
The Inhibition of the Corrosion of Iron by Some Anodic Inhibitors
Inhibitors having relatively strong oxidizing anions, such as sodium chromate and nitrite, passivate iron both in the presence of air and in deaerated solutions. Much weaker oxidizing agents such as sodium tungstate and molybdate behave similarly to chromate and nitrite in the presence of air but do not prevent corros…
