The negative difference effect in the case of steel can be explained in terms of corrosion by removal of blocks or "chunks" of metal containing perhaps only a few atoms. The "chunk effect" also explains the observed fact that, under conditions of high corrosion rate, minimum protective current can be much less than th…
Evidence is presented to show that the load drops observed in most metals at very low temperatures arise from thermal instability rather than mechanical instability of the lattice. Measurements of the temperature rise are described.

An improved method is presented for determining those three molecular field coefficients which yield essentially the best agreement between the Néel theory and the experimental curve of saturation moment per unit mass (σ) versus temperature (T) in a given ferrimagnetic material. This method is analytical, and for a gi…

Rate studies were made for the oxygen‐free reaction between steel powder and , both uninhibited and inhibited. In particular, it was shown that the retardation of the reaction by organic polar compounds was influenced more markedly by molecular structure than by molecular weight or area.
The dielectric constant and loss have been measured for several linear polyamides over a range of frequency and temperature. At low frequencies and elevated temperatures, proton conduction through the amorphous regions gives rise to a Maxwell-Wagner loss, while at high frequencies and high temperatures dipole relaxati…
Abstract The nature of the intermolecular interactions involving the CN groups in organic nitriles has been investigated through comparison of the physical properties of nitriles and other organic liquids. Evidence is presented that hydrogen bonding is not a significant factor in these interactions. The CN groups tend…

Evidence is presented in this paper to show that crystals present a pla8tic 'resistarwe to dislocation motion. This has been demonstrated by direct observations of dislocations in LiF crystals by Johnston and Gilman, and in Fe-Si crystals by Stein and Low. The plastic resistance is almost independent of dislocation ve…

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…
