Abstract The wave‐vector dependent dielectric function for LiCl, LiBr, LiI, NaCl, NaBr, Nal, KCl, KBr, and KI is calculated using a model originally proposed by Fry. An approximate analytical expression for the screened Coulomb potential is also given.

Abstract Results are presented of a study of the Hall effect (in the low‐temperature range 20 to 300 °K) and of the thermopower of the monocarbides VC x , NbC x , and TaC x within the limits of their homogeneity regions. Basing on the experimental results obtained and on earlier data on magnetic susceptibility and ele…
Abstract High molecular weight poly(ethylene sulfide) undergoes severe thermal degradation at the high temperatures (220–260°C) required for processing in injection‐molding equipment. Thermal degradation of the polymer is accompanied by gas evolution and a decrease in melt viscosity. Stabilization of poly(ethylene sul…
The variation of the postirradiation creep-rupture properties with irradiation temperature has been evaluated for air- and vacuum-melted Hastelloy-N.The air-melted material was high in silicon and ...

The thermal decomposition of oxalates of ammonium and potassium was studied by simultaneous TGA, DTA, and EGA (effluent gas analysis). Of the simple oxalates, the potassium compound is more stable than the lithium compound, as has been observed for the corresponding carbonates and sulfates. Ammonium oxalate is much le…
The process of large strain plastic deformation, such as commonly found in the machining process, has been investigated by transmission and scanning electron microscopy techniques. The lamella-shear front nature of deformation in copper and aluminum chips has been elucidated fully and the occurrence of lamellae has be…
Magnetic susceptibility and specific heat of the β-MnO 2 powder specimen have been measured in the range 20 to 300°K and 77 to 100°K respectively. The measurements have also been made for the paramagnetic inelastic neutron scattering at room temperature by using time-of-flight method. The values of the Weiss temperatu…

The literature on intergranular corrosion of austenitic stainless steels is reviewed, with particular reference to the theories of intergranular corrosion and the connexion between carbide morphology and the corrosion susceptibility. In the Strauss solution, intergranular corrosion is due to the formation of a chromiu…
A two-dimensional polynomial method is described which allows rapid evaluation of bond-scattering factors in a structure factor least-squares program. Correlation effects between electron population parameters are analyzed. It is concluded that simultaneous refinement of 2s2 and three 2p2 one-center populations is not…

Enthalpy content measurements on pure KCl, AgCl, CuCl, PbCl 2 , Ag 2 S, and PbS were made at temperatures up to 1000 °C using a sapphire calibrated drop calorimeter. Similar measurements were performed on AgCl–Ag 2 S and AgCl–KCl melts. These results determined values for the integral enthalpy of liquid–liquid mixing.
Abstract The effect of temperature and strain rate on the compressive yield behavior of polystyrene is compared with the effect of the same variables on crazing in tension. The results support the conclusion of other, more extensive work, which shows that crazing involves the same types of molecular processes as those…
Abstract The effect of ammonium sulfate, ammonium chloride, potassium chloride, calcium chloride, aluminum chloride, and copper sulfate added in amounts corresponding to 0.2, 2, and 20 atm concentration on mineralization of soil nitrogen in three soils was measured over a 30‐day period. Significant increases were prod…
Abstract Dynamic mechanical measurements were carried out as a function of temperature (−100 to + 180°C) and frequency (3.5 to 110 cps) for a series of aliphatic terpolyamides, nylon 6 and nylon 12. Effect of crosslinking with toluene diisocyanate, of absorbed water, and of frequency are used to estimate the statistic…

Abstract Several different schools of workers have dominated research in the field of polymer mechanochemistry. These include the Russian school with Baramboim, Berlin, Butyagin; Watson, Ceresa and others of the Natural Rubber Producers' Research Association; and a host of other European workers. Also active are the J…
