Size effect variation of the electrical conductivity of metals

David Keith Chalmers Macdonald、Kathleen Sarginson1950-09-22Proceedings of the Royal Society of London A Mathematical and Physical Sciences

Abstract This paper records experiments and theoretical work concerned with the variation of conductivity with size in metals. Experimental results for the conductivity in thin wires of pure sodium of varying diameter in the absence of a magnetic field and also in the presence of longitudinal and transverse magnetic f…

Free Retraction of Elongated Rubbers

Beitske Boonstra1950-09-01Rubber Chemistry and Technology

Abstract The speed of retraction of the ends of elongated rubber rings relative to each other for a number of elastomers was measured at room temperature by a comparatively simple method. The results, plotted as elongation vs. time curves, indicate that the mechanism of retraction is complicated and cannot be describe…

Investigations in the Field of Rubber Vulcanization. VII. Influence of Organic Accelerators on the Kinetics of Vulcanization and the Properties of Natural-Rubber Vulcanizates

B.A. Dogadkin、B. Karmin、A.V. Dobromyslova 等 4 位作者1950-09-01Rubber Chemistry and Technology

Abstract 1. Vulcanization accelerators change all parameters of the kinetic strength curve during the vulcanization of natural-rubber mixtures with low sulfur contents. 2. Calculation of the kinetic constants of the fundamental vulcanization equation proposed by Dogadkin, Karmin, and Gol'berg shows that vulcanization…

Corrosion of Metals in Fluorine And Hydrofluoric Acid

G. Whitaker1950-09-01CORROSION

Experience gained over a period of years in the use of metal equipment for the production and handling of fluorine and for the production and shipment of hydrofluoric acid has resulted in an accumulation of information relative to the behavior of metals under various conditions. None of the common metals or alloys hav…
