Abstract The pure salts Na 2 S 2 , K 2 S 2 , K 2 S 3 , Na 2 S 4 , K 2 S 4 and K 2 S 5 have been prepared. Titration curves of these polysulfides in aqueous solution have been obtained with a special streaming apparatus, with which the mixing of the polysulfide solution with HCl and the pH determination of the fresh mi…

After a short résumé of the general ideas and assumptions of the independent-particle model of a metal, an account is given of the experimental methods which have been, or may be, used to determine the details of the model for any given metal, with special reference to the shape of the Fermi surface and the electronic…

Abstract : The study of the deposition processes in pyrolytic graphite, made from the gas phase, has been largely empirical. The work presented attempts to show that the deposition is controlled by reactions in the gas phase. Experiments were performed at fast and slow rates of growth using natural, pyrolytic, and com…

The rate of oxidation of zirconium followed a cubic rate law in the temperature range 400°–900°C at oxygen pressures of 50, 200, and 800 mm. At 200 mm the activation energy was calculated to be 42.7 ± 0.7 kcal / mole . The oxidation of zirconium binary alloys containing 1, 2, and 4 atom % of aluminum, beryllium, carbo…
The mechanism of dislocation loop formation by vacancy condensation is examined in a quantitative manner. The critical vacancy supersaturation necessary for the growth of the loops and the climb rate of the dislocations are determined. It is shown that the mechanism proposed for lineage formation based upon loop growt…

Silver selenide has been prepared by fusion techniques and found to be a good thermoelectric material. The Seebeck coefficient, resistivity, and thermal conductivity have been measured as a function of temperature. The effect of doping with 30 different elements and compounds at different doping concentrations has bee…
When copper disks rotate in sulfuric acid solutions, the observed rate of dissolution is first order with respect to the concentration of dichromate ion used as a depolarizer. By studying the effect of temperature and stirring speed at high and low acid concentrations, the process is shown to be determined completely…

Lead zirconate titanate ceramics with certain 3- or 5-valent additions (lanthanum, neodynium, tantalum, and niobium) are found to be characterized by low aging of electrical and mechanical properties, a well-defined hysteresis loop, and by high electrical and mechanical losses. Experimental investigations are reported…
Abstract The active transports of sodium and chloride ions, between the vacuole and environmental solutions, were measured in the giant coenocyte of the marine alga Halicystis ovalis. Ion fluxes, determined isotopically, of individual single cells were measured by the short‐circuit technique of U ssing and Z erahn (19…
Abstract Results of new research work in the field of polymers with an ordered steric structure, obtained by stereospecific polymerization, are reported. Some of the results concern the relationship between steric structure and crystallinity; from these it results that a regular steric structure is a necessary, but no…
