The Atomic Distribution in Red and Black Phosphorus and the Crystal Structure of Black Phosphorus
No satisfactory crystal structure determination has been made of any of the forms of phosphorus. Five samples of black phosphorus gave identical powder patterns different from those reported by Linck and Jung, whose rhombohedral structure gives improbable interatomic distances and coordination. A sample which had been…

Ferromagnetic Distortion of a Two-Frequency Wave
Frequency components are found for the ferromagnetic induction produced by a small magnetizing force of two incommensurable frequencies. Because of hysteresis the results depend intimately upon the ratios of these frequencies and of their amplitudes. With these ratios as criteria, two solutions are provided, adequate…

Internal Dissipation in Solids for Small Cyclic Strains
This paper presents the results of investigations of dissipation of energy in vibrating solids, mostly metals, by means of longitudinal and torsional vibrations of cylindrical rods. The amplitudes of strain used have been kept between 10−5 cm/cm and 10−8 cm/cm, in which range the dissipation of energy is proportional…

On the Plasticity of Crystals
In the following, a theory is given with the purpose of establishing a mathematical relation between the stress and the strain in a crystal when plastically deformed. The existence of a "secondary structure" in crystals is adopted as a basic hypothesis. This structure was pointed out by Professor F. Zwicky to be a con…

Buckling of Flat Curved Bars and Slightly Curved Plates
Abstract This paper considers the case of the flat arch and the slightly curved plate, with uniformly distributed load, which may fail not as a result of high stresses and yielding of the material but because of instability, and it is shown how the critical load at which buckling occurs may be calculated. The case of…

Precision Lattice Constants from X-Ray Powder Photographs
A very general method is given for the calculation of lattice constants from powder photographs in which there is taken into account the various systematic errors inevitable in such photographs, including radius errors, film shrinkage, absorption, eccentricity and finite slit height. While the solution of the data is…
The Action of Milk Fat as a Foam Depressant
Summary The action of the milk fat in milk as a foam depressant has been discussed in connection with the theories which have been proposed to explain the phenomenon. The consequences of these theories have been investigated experimentally. Contrary to some of the ideas expressed adsorption experiments indicate that t…
Molecular Arrangement and X-Ray Diffraction in Ionic Solutions
Solutions containing heavy ions in water were examined with Cu Kα radiation, care being taken to avoid effects of general radiation. The diffraction patterns of saturated solutions of Th(NO3)4 and UO2(NO3)2 consist mainly in a pronounced ring, shifting to smaller angles and getting fainter with increasing dilution. Th…

Properties of Rochelle Salt
Measurements of the dielectric, pyroelectric, optical and electro-optical properties of Rochelle salt, and a theory correlating all observations are given. The theory is based on the assumptions that all properties depend on the inner field $F=E+fP$, and that the Curie point changes with temperature. The theory explai…
Electron tubes: Part 2. The high-speed cathode-ray oscillograph
From the first production of Geissler discharges and through the early experiments of Sir J. J. Thomson to determine the values of e, elm and ZI for cathode rays and the early attempts in the same year of Braun to apply cathode rays to commercial measurement, the history of the cathode ray oscillograph is admirably tr…
Das Lichtbrechungsvermögen der Cellulose in Funktion des Quellungsgrades
Abstract 1. Für die Messung des Brechungsvermögens von quellbaren Kolloiden muss die Immersionsmethode (Umhüllungsverfahren) angewendet werden, die die Brechungsindices des Mischkörpers als Ganzes misst. Die Imbibitionsmethode (Durchtränkungsverfahren) ist dazu ungeeignet, da diese die optische Gleichheit der Messflüs…
