Abstract The official method for iodine in iodized salt, 31.064–31.067, was studied to determine interference from sodium thiosulfate added as a stabilizing agent; no interference was found. The present official method for iodine in iodized salt is reliable, and study of methods should be discontinued.

Physical and mechanical properties of aluminum- mylar-aluminum composite material for Echo II BALLOON
New data obtained on the join Ca 2 SiO 4 ‐CaMgSiO 4 established a limit of crystalline solubility of Mg in α‐Ca 2 SiO 4 corresponding to the composition Ca 1.90 Mg 0.10 SiO 4 at 1575°C. The α‐α’Ca 2 SiO 4 inversion temperature is lowered from 1447° to 1400°C by Mg substitution in the lattice. α'‐Ca 2 SiO 4 takes Mg in…
The accumulation of irradiation damage in graphite crystals under neutron irradiation at temperatures between 150°c and 650°c is discussed using recent ideas on nucleation of planar clusters of interstitial atoms and the collapse of lines of vacant lattice sites produced by chance sequences of atomic displacement. It…
The corrosion of downward‐facing surfaces has often been associated with the presence of gas bubbles. Model work with methanol‐water and other systems has shown that rapid upward drilling does occur around gas bubbles. A mechanism is suggested which could also be applied to flux‐line attack.
Abstract A method is described for the conversion of polystyrene to poly(styrenesulfonic acid) without change in the molecular weight distribution; the reaction is performed at room temperature in 100% H 2 SO 4 and uses Ag + catalyst. The resulting polyelectrolyte has solubility and other characteristics significantly…

Although certain liquids show Arrhenius viscosity behavior over the whole liquid range, most liquids have a substantial non-Arrhenius range in which their viscosity is described by the free-volume equation. In a few supercooled liquids, there are two distinct non-Arrhenius regions. From a calculation of the volumes re…
The ESR spectra of the powder samples of cubic ZnS:Mn, hexagonal ZnS:Mn, and CdS:Mn are treated theoretically for the case where the exchange interaction exists between the Mn 2+ ions. The comparison of the calculation with experiments indicates that, for a pair of Mn 2+ ions, the resonance spectra are well described…
Abstract Epitaxial deposition of homopolymers from solution [polyethylene, isotactic polystyrene, poly‐3,3‐bischloromethyloxacyclobutane (Penton) and polypropylene] was found on the (001) faces of cleaved alkali halide single crystals. Electron and optical microscopy studies have shown that the polymer usually grew fr…

The effect of pressure to over 200 kbars has been measured on the lattice parameters of iodine, stannic iodide, and of p-di-iodobenzene. All three have a large component of van der Waals binding and each exhibits a compressibility which decreases with increasing pressure. On the basis of the estimated change in distan…

The ionic transport number and the d-c. electrical conductivity of single-crystal and polycrystalline alumina have been studied between 1 000 °K and 1 750 °K at an oxygen partial pressure of 0.2 atm. The ionic transport number was determined by the galvanic-cell e.m.f. measurements; the electrical conductivity was mea…
