In connection with Galt and Herring's observation on thin whiskers of tin, the properties of a screw dislocation in a cylinder are worked out. When all boundary conditions are taken into account, the image force tends to keep the dislocation along the axis. Only when it is displaced about half-way to the surface does…

Some factors affecting the solubility of polymers

P. A. Small1953-02-01OpenAlex

Abstract The solubility of a polymer in a non‐polymeric liquid depends mainly on the heat of mixing. When no polar forces are concerned, the cohesive energy densities of polymer and solvent must be close; a method is given for estimating the cohesive energy densities of polymers from a set of additive constants, and i…

Compression Strength of Porous Sintered Alumina and Zirconia

Eugene Ryshkewitch1953-02-01OpenAlex

The influence of controlled porosity on the compression strength of sintered pure alumina and of partly magnesia‐stabilized zirconia was investigated. Bodies with porosities ranging from approximately 3 to 60% by volume were prepared utilizing hydrogen peroxide to induce pore formation. Cubes of approximately 1.2‐cm,…

States of Solid Methane as Inferred from Nuclear Magnetic Resonance

Kazuhisa Tomita1953-01-15Physical Review

As there are different points of view concerning the molecular dynamical states in solid methane, especially concerning the $\ensuremath{\lambda}$-transition at 20.42\ifmmode^\circ\else\textdegree\fi{}K, we have investigated the manner in which the new method of nuclear magnetic resonance throws light on the problem.…

Neuere Ergebnisse der präparativen Hydrid‐Forschung

Egon Wiberg1953-01-07Angewandte Chemie

Abstract In den letzten 10 Jahren konnten, besonders nach der Auffindung des Lithiumaluminiumhydrids, zahlreiche neue Metallhydride und ‐doppelhydride entdeckt werden. Die Dreiteilung der Wasserstoff‐Verbindungen in salzartige, metallische und flüchtige Hydride hat sich bestätigt, wenn auch überall gleitende Übergänge…

Influence of Addition of Nickel on the Thermal Expansion, Rigidity Modulus and Its Temperature Coefficient of the Alloys of Cobalt, Iron and Chromium, Part I. Alloys with 10 and 20 Percent of Nickel

Hakaru Masumoto、Hideo Saitô、T. Kono1953-01-01Journal of the Japan Institute of Metals and Materials

The influence of an addition of 10 percent and of 20 percent of nickel on the thermal expansion in the range of 10° to 50°, rigidity modulus at 20° and its temperature coefficient in the range of 20° to 50° of the alloys of cobalt, iron and chromium has been examined. The relations between those properties of nickel-a…

Effect of Germanium on the Transformation of White to Gray Tin, at Comparatively Low Temperature

Raymond R. Rogers、J. F. Fydell1953-01-01Journal of The Electrochemical Society

At a comparatively low temperature, gray tin may appear on white tin when the latter ( a ) is in contact with elementary germanium, ( b ) contains a certain proportion of germanium in the form of an alloy, or ( c ) is in contact with solutions in which certain germanium compounds have been dissolved. Data also are pre…

Physico-chemical Studies on the Skin and Leather of Marine Animals-VIII

Toyo-o TAKAHASHI、Takeo Tanaka1953-01-01NIPPON SUISAN GAKKAISHI

The purpose of the present work is to obtain essential scientific knowledge on which basis an efficient method may be established for manufacturing leather or glue from the fish skin. With this view in mind, we measured the shrinkage temperature (Ts) of the animal skin. Specimens of which skins were employed as the te…

SUANITE, A NEW MAGNESIUM BORATE MINERAL FROM HOL KOL, SUAN, NORTH KOREA

Takeo Watanabe1953-01-01Mineralogical Journal

A new mineral from the Hol Kol mine, North Korea of the composition Mg2B2O5, named suanite, has been described. The mineral is found usually as fibrous aggregates associated with kotoite and other borate minerals in marble which borders the gold-and copper-bearing diopside-clinohumite skarn mass. The crystal usually e…

Preparation and Properties of Iodide Vanadium

Julian W. Nash、H.R. Ogden、Richard E. Durtschi 等 4 位作者1953-01-01Journal of The Electrochemical Society

Massive vanadium was prepared by the hot‐wire reduction of vanadium iodide vapor by both the Van Arkel‐de Boer method and a straight‐flow process. The iodide decomposition provides an excellent method of obtaining small quantities of vanadium exceptionally low in nonmetallic impurities. Metal prepared by the straight‐…
