To examine the conditions brought about upon initiation of core spraying, a 36-rod assembly was heated to different temperatures and then spray cooled. The runs were made at atmospheric pressure using two kinds of assemblies, both made up of heater rods of 15 mm outer sheath diameter, arayed into 6×6 lattice accommoda…

No general theory exists that can predict the efficiency of phosphors with electronic transitions in localized centers. In this paper a survey and discussion are given of the correlation between fluorescent properties and chemical properties, like composition and structure. Points of discussion are ( a ) choice of the…

Abstract Thin films of n‐conducting In 2 O 3 are prepared by reactive sputtering. The concentration of conduction electrons is changed by a heat treatment between n e = 10 17 and 10 20 cm −3 ( T = 300°K). Concentration and temperature dependence of the electron mobility indicate an intense scattering at charged imperf…

Abstract Besides the so-called β-Al2O3 (R2O·11Al2O3; R=Na or K), there have been found two kindred compounds with approximate formulas, R2O·7Al2O3 (β′-Al2O3) and R2O·5Al2O3(β″-Al2O3). The structure determination of the latter two compounds was undertaken; the results are compared with the structure of β-Al2O3 in the p…

On heat treatment in air the solubility of MgO or TiO 2 , in Al 2 3 is too small to detect by lattice parameter shifts. The solubility of MgTiO 3 in Al 2 O 3 in air increased to the measured values, expressed as atomic fractions Mg:A1or Ti:A1of0.82 × lo‐ 2 , 1.43 × 10 ‐2 , and 1.75 × 10 ‐2 at 1250°, 1650°, and 1850°C,…

The theory of Rayleigh scattering from density fluctuations is applied to data taken in glycerol and n-butanol over wide temperature ranges. It is shown that Brillouin scattering is useful in evaluating the viscoelastic parameters of a liquid when all corrections are properly applied. The position, half-width, and int…

Abstract Empirical size‐dependent growth rate models are studied for their effect on the population density distributions from a continuous, mixed suspension, mixed product removal (CMSMPR) crystallizer. The growth rate models and/or their corresponding population density distributions are examined for continuity, con…

The behaviour of the magnetic properties of the 4T1g term under simultaneous perturbation by spin–orbit coupling and an axial ligand-field is presented. The theory is applied to the variation with temperature of fifteen octahedral cobalt(II) complexes in the range 80–300°K. The values of k, the orbital reduction facto…

Amorphous ice prepared by slow condensation of water vapor onto a surface cooled with liquid nitrogen or liquid hydrogen undergoes several exothermal transformations on warming. Thermal analysis by means of warming curves indicates that the heat liberated on warming ice prepared at − 253°C is 8 cal/g from − 253° to −…

Nitrous oxide reacts rapidly in solution at room temperature and at atmospheric pressure with a number of transition-metal complexes. It reacts with the cobalt(I) corrin, vitamin B12s, in aqueous solution according to the stoicheiometry 2CoI+ N2O → 2CoII+ N2 and with [CoI(Ph2P·CH2·CH2·PPh2)2]Br in benzene or ethanol a…

Critical pitting potentials for the binary Cr‐Fe and Cr‐Ni alloys in 0.1 N NaCl become more noble (correspondingly more resistant to pitting) with increasing Cr content, particularly in the region 25–40% Cr and 10–20% Cr, respectively. The potentials for 57.8% Cr‐Fe and pure Cr fall within the transpassive region. Ni…
