A picture of the early stage of graphitization of a carbon black has been obtained from an x-ray study of a Fine Thermal (FT) carbon black heated for two hours at 2300°C. Nearest neighbor pairs of layers take on the graphite relation independently, producing both ABA and ABC sequences. There are two nearest neighbor l…

The consequences are analyzed of the following two assumptions: (1) the effect of temperature upon magnetic anisotropy arises solely from the introduction of local deviations in the direction of magnetization; and (2) the local deviation in an elementary region is the resultant of a very large number of independent de…
Summary The mesomorphic or “liquid crystalline” neat and middle phases encountered in aqueous systems of soaps and synthetic detergents differ considerably in plasticity. Nevertheless, in fundamental phase studies or the examination of commercial products and processes, identification of these two phases has hitherto…
An equation for the activation energy of ionic conduction in silica glasses is developed. The approach uses the classical ideas of ionic crystal theory and elasticity theory. The equation finally derived involves the radius and valence of the modifier ion, the lattice constant of the glass, the electronic charge, the…
Abstract The infra-red spectrum of several synthetic polypeptides with small side chains (polymers of glycine and alanine) have been examined in the region 800 to 1700 cm-1. The observations include measurements with polarized radiation on the α (folded) and β (extended) forms of poly-L-alanine; deductions from these…
Abstract Single-crystal test specimens of van Arkel titanium were obtained by a modification of the strain anneal technique.The modes of slip have been identified as (101̄0) [112̄0],(101̄1) [112̄0], and (0001) [112̄0]. It has been shown that not only does the interstitial impurity affect the magnitude of the critical…
Fabric dust collectors are used industrially for the separation of dusts and fumes from air and gases in many manufacturing and material handling processes.As a class, these collectors are generally greater than 99% efficient by weight on dusts ranging from SO microns to the submicron sizes, when inlet dust loadings e…

Ultrasonic absorption coefficients (at about 8 Mc/sec) were determined by the pulse technique in glycols, cyclohexanol and m -cresol in dependence of the temperature. Also the ultrasonic velocity (at 1.43 Mc/sec) in these liquids was determined by the ultrasonic interferometry. The experimental absorption coefficient…
Abstract Die Darstellung von reinstem K 2 MnO 4 wird beschrieben. Die thermische Zersetzung von K 2 MnO 4 im O 2 ‐ und N 2 ‐Strom im Temperaturbereich 500° bis 900° wird untersucht. Durch quantitative Aufarbeitung des Reaktionsproduktes wird gezeigt, daß diese Zersetzung im Prinzip stets nach der Gl. (3) K 2 MnO 4 = 2…

The Raman spectra of crystalline NH3 and ND3 were measured at —82°C, using Hg 2536.5A exciting radiation. The fundamentals v1, v2, and v3 were observed, but v4 was not. v2 was split into two components by intermolecular coupling. Lattice frequencies of both translational and rotational origin were observed, and there…
Results of an investigation of some properties of the systems CaO‐B 2 O 3 , SrO‐B 2 O 3 , and BaO‐B 2 O 3 are reported. The formation of two liquids at low RO concentrations limited the range of compositions which could be measured. The values of surface tension and temperature coefficient of surface tension obtained…

Measurements of resistivity, Hall coefficient, and optical absorption of AlSb are reported. The width of the forbidden energy band, derived from electrical and optical data, is 1.6 ev at absolute zero. Absorption bands are observed at 0.75 ev in $p$-type samples and at 0.31 ev in tellurium-doped $n$-type specimens. An…
On the basis of a simplified model an explanation for the high-frequency limit of ultrasonic cavitation is suggested and compared with published experimental data.
The near infra-red region may be used to obtain spectra with polarized radiation of natural and synthetic fibres. This region has considerable experimental advantages and the spectra of poly-L-alanine, polyglycine, wool, silks and commercial regenerated protein fibres are shown and discussed. Besides supplementing oth…
