CHARACTERISTIC VIBRATIONS OF THE SULPHURYL GROUP
A compilation of the S—O symmetric and asymmetric stretching frequencies is given for a large number of compounds containing an —SO 2 — group. It is shown that a linear relationship between [Formula: see text] is valid for a large number of sulphuryl and polysulphuryl compounds and that the actual frequencies depend i…
X-Ray Studies on Solid Solutions of Oxygen in a-Zirconium.
ABS>The solubility of oxygen in alpha -zirconium in the temperature region, 400-800 deg C, was investigated by x-ray methods. The solubility, which is independent of temperature, is 28.6 at.% (ZrO/sub 0.4//sub 0/). With increasing oxygen content, the length of the c axis increases over the entire solubility range whil…

Diffusion Coefficients of Helium in Fused Quartz
The diffusion of helium through the walls of high-purity fused quartz hollow cylinders was studied using a mass spectrometer as a detecting device. By surrounding the outside of the hollow cylinder with helium and observing it diffuse through into the mass spectrometer, permeation rates and diffusion coefficients were…

Devitrification of Natural Glass
Many aspects of the history of natural glasses are related to the physicochemical properties of silicate melts. Glasses are thermodynamically unstable; with time and under a variety of conditions, they become crystalline. When little water is present, devitrification may be described in much the same terms as those wh…

Passivity and Corrosion Resistance of Titanium and Its Alloys
A brief review is given of possible ways to increase corrosion resistance of titanium in acids proceeding from analysis of its electrochemical characteristics and passive state stability. Rational ways of alloying titanium for acid resistance are indicated. Experiments include titanium alloys with palladium, chromium,…

Note on a Phase Transition in VO2.
The powder diffractogram of vanadium dioxide crystals was found to change, rapidly and reversibly, at about 70 deg C, the most obvious feature being the disappearance of all reflections hkl with h odd. At 180 deg C the effect was even greater and the crystal structure was derived and found to be essentially of the rut…

THE FORMATION OF FIBRILS FROM COLLAGEN SOLUTIONS
The kinetics of collagen reprecipitation from solutions of salt-extracted calf dermis in the presence of small amounts of mucopolysaccharide and nucleic acids (0.005 per cent in the final reaction mixture) has been reported by Wood (1960). The present paper is a parallel study using the same materials, and describes t…
Cation Diffusion in Cr[sub 2]O[sub 3]
On employing a sectioning technique with Cr 51 as the tracer, the diffusion of Cr ions in nitrogen‐equilibrated was determined from 1045° to 1550°C. Volume diffusion coefficients in hot‐pressed compacts of three different impurity levels conform to the expression . Additions of and do not cause a significant change. U…
Elastic Constants of Single Crystals of the bcc Transition Elements V, Nb, and Ta
Values of the elastic constants of single crystals of the bcc transition elements V, Nb, and Ta, are reported at T=27°C.

Crystal Distortion in Copper Ferrite-Chromite Series
The cation distributions in copper ferrite-chromite series and the copper ferrite quenched from high temperatures are measured by X-ray diffraction method. The lattice parameters are also measured as a function of chromium ion content and of temperature. The critical fractions of copper ions on 16d and 8a sites for th…
On the determination of the crystalline fraction of isotactic polypropylene from x‐ray diffraction
Abstract A simple procedure for the determination of the crystalline fraction in isotactic polypropylene, suitable for routine work, is described. It gives lower figures for the crystalline fraction than the method recommended by N ATTA , C ORRADINI , and C ESARI in 1957. The correctness of the results (within the lim…
