Experimental data on the physical solubility of gases in fused silica are presented. A “free” volume for fused silica was calculated from these solubilities and was compared to the free volume calculated by other methods. The relation of this free volume to the molecular structure of fused silica is also discussed.
Curie points, the temperature dependence of the high-field magnetization below room temperature, saturation moments, and densities are reported for the most iron-rich compounds in the rare earth-iron systems. The heavy rare earth compounds have the composition A2Fe14and the hexagonal Th2Ni17-type structure, while the…

Characteristic flow properties for each of the three nominal mesophase types have been empirically established. Results are given for the nematic, smectic, and cholesteric types of mesophase. Discussion is centered on mesophases or liquid crystals exhibited by pure compounds within defined temperature intervals betwee…
The results of compressive strain-rate tests on 6061-T6 aluminum, 7075-T6 aluminum, 6Al-4V titanium fully annealed, pyrolytic graphite, lucite, and micarta for rates of loading of 10−3 to 104 in/in/sec are presented. A medium strain-rate machine and a split Hopkinson bar apparatus used to conduct these tests are descr…
Diffusion measurements in pure iron have been made in the temperature ranges 683 to 884°c and 1428 to 1521°c. The following expressions for diffusion coefficients, D, are deduced from least mean squares analyses of the results: A single Arrhenius equation describes the diffusion data obtained above the Curie temperatu…
The free radicals CH3, SiH3, GeH3, and SnH3 have been produced in a krypton matrix at 4.2°K by γ irradiation of the matrix containing dilute concentrations of CH4, SiH4, GeH4, and SnH4. The electron spin resonances indicate free or restricted rotation for all the radicals in the matrix. Observed anisotropies in g show…
Values for the physical solubility of nitrogen as well as for the content of chemically dissolved nitrogen in glass melts are given. The form in which the nitrogen is present in the glass melts is discussed and an attempt is made to explain chemical interaction between nitrogen and the glass melt. The dependence of th…
Abstract Soluble collagen from guinea pig skin has been subjected to sequential digestion with purified collagenase and trypsin. The small quantity of hexose present in the collagen can be detected in the digest largely as relatively basic glycopeptides. One of these glycopeptides has been obtained in pure form and ac…
Abstract The following model conception describing heat transfer in amorphous materials, especially in high polymers, is derived. An “elementary” thermal resistance is assigned to each bond between adjacent atoms. The thermal resistance of a macroscopic amorphous specimen is that of a three-dimensional network consist…
Abstract Considerable stress softening occurs in both gum and filler-loaded vulcanizates and when compared at the same stress the extent of softening is similar in both gum and filled vulcanizates. It thus appears that the softening process is mainly due to the rubber phase alone. Apparent differences between the stre…
Abstract A model has been developed to study chemical reactions which occur in oxygen‐nitrogen mixtures during very rapid cooling in small‐diameter tubes. The system considers both homogeneous gas phase reactions and surface reactions based upon a simplified mass transfer mechanism. With an energy balance used to dete…

Abstract This paper analyzes the growth or collapse of a spherical bubble in an incompressible, viscous fluid. Theoretical results include the timewise variations in the bubble size and its growth or collapse rate, the fluid pressure, and the rate of energy dissipation. The analysis is general and may be applied to bo…
The incorporation of slip dislocations at the coherent twin boundary has been analysed for the (112) [111] type twins in hexagonal close-packed zinc crystal by applying matrix algebra. The effects of the various dislocation incorporation processes on the growth and untwinning of the existing twin are discussed from th…
Controlled antiferromagnetic domain reversals have been observed in single crystal Cr2O3. Switching between substantially single domain states has been achieved with the simultaneous impression of electric and magnetic fields of approximately 10 kV/cm and 5 kOe, respectively. The switching energy is closely proportion…
The relation between self-diffusion coefficients and grain boundary energy proposed by Borisov et al. (1964) has been examined for various metals. Satisfactory agreement was obtained between observed and calculated values.
Abstract An Hand der bekannten Bewegungsgleichungen für ein einzelnes Feststoffteilchen werden die Voraussetzungen diskutiert, unter denen eine exakte Berechnung der Bewegungsbahnen möglich ist. In zwei Sonderfällen, der Teilchenbewegung ohne Einfluß der Schwerkraft und der Teilchenbewegung in der Vertikalen mit Berüc…
