A study of the Zeeman effect of absorption lines of GdCl3·6H2O and its dependence on the orientation of the crystal has given the constants for the magnetic ellipsoids for the ground state and 11 excited states. Evidence is presented for identifying the first three absorption groups as transitions from 8S to 6P7/2, 6P…

Previous studies of the kinetics of dehydroxylation of kaolinite and halloysite point to first‐order reactions, in approximate conformity with the Arrhenius relation. Isothermal weight‐loss measurements have shown that the rate constants are markedly dependent on factors such as specimen size, shape, and compaction. A…

Upon depoling ceramic barium titanate, up to 9% of the domains reorient by 90°, indicating that during poling at least this percentage of the domains was permanently reoriented by 90°. Ceramic barium titanate shows a strong anelastic effect in the ferroelectric state, presumably due to domain reorientations under stre…
Magnetic properties of the synthesized solid solution x FeTiO 3 ·(1- x ) Fe 2 O 3 of ilmenite (FeTiO 3 ) and hematite (Fe 2 O 3 ) were investigated in detail for the whole range of 0≦ x ≦1. On the experimental side of the study, the most suitable method for preparing the specimen with the largest intensity of magnetiz…

Abstract Durch Auswaschen des frisch bereiteten Graphitoxyds mit salzsäurehaltigem Chlordioxydwasser wurde unter Ausschluß von Lieht ein auch nach dem Trocknen noch helles Produkt erhalten. Das helle und das übliche dunkle Graphitoxyd aus der gleichen Herstellung haben die gleiche chemische Zusammensetzung. Durch Umse…
An expression for the steady-state creep rate of crystals is derived for the case where dislocation climb is not rate controlling. Two rate-controlling processes are considered. In the first the dislocations are considered to move in a viscous manner, their velocity of motion being proportional to the force exerted on…

The piezoelectric effect of bone has been observed similarly to the case of wood or ramie. The specimens were cut out from the femur of man and ox, and dried completely by heating. The piezoelectric constants were measured by three different experiments, that is, measurements of the static direct effect, the dynamic d…
A detailed model for the crystal structure of the fibrous polysaccharide chitin is proposed. The structure determination has been carried out by using an optical analogue instrument which proved to be an adequate and rapid tool for the derivation of Fourier transforms, signs of amplitudes and the production of optical…
