The crystal structure of NaBiS2 and KBiS2
Abstract NaBiS 2 and KBiS 2 both have the NaCl structure with Bi 3+ and Na + (resp. K + ) in averaged structure. The cell dimensions are 5.76 Å for NaBiS 2 and 6.01 Å for KBiS 2 . The ionic radius of Bi 3+ is discussed.
The hydrothermal solubility of silica
The solubility of silica glass in water has been determined through the temperature range 200 degrees C. to 420 degrees C. at a pressure of 300 atmospheres. Some previous investigations of solubility of silica in water, it is believed, have indicated a too great solubility as a result of failure to distinguish true so…
The vulcanization of rubber with phenol formaldehyde derivatives
Abstract After some remarks on the importance of phenol formaldehyde resins as vulcanizing agents for rubber, the introductory investigations which led to the methylene quinone theory of the vulcanization are described. Finally this theory is illustrated with the compound 2.6‐di‐bromomethyl‐4‐methylphenol as an exampl…
The vulcanization of rubber with phenol formaldehyde derivatives
Abstract Referring to the preceding article describing the methylene quinone theory of the vulcanization of rubber with phenol formaldehyde derivatives, in this paper the arguments in favour of that theory are considered in detail. The results of the investigations in question can be summarized as follows. The vulcani…

Über den Einflusss von Gitterstörungen auf das Röntgendiagram, im Besonderen bei Gelen
The influence of two extreme types of lattice distortions on the X‐ray diagram is demonstrated with the help of a simple one‐dimensional model. In the first type the displacements of the lattice points from their original positions are mutually independent, while in the second type of distortion a similar independence…

Effect of Strain Rate Upon Plastic Flow of Steel
An experiment has been designed to check a previously proposed equivalence of the effects of changes in strain rate and in temperature upon the stress-strain relation in metals. It is found that this equivalence is valid for the typical steels investigated. The behavior of these steels at very high rates of deformatio…

The Apparent Second-Order Transition Point of Polystyrene
(1) At high temperatures (above 80°C) the specific volume of polystyrene is an explicit function of the temperature. dV/dT=0.00043. (2) At low temperatures (below 40°C) the specific volume of polystyrene depends upon its past thermal history dV/dT=0.00024, although V is not explicitly fixed by the temperature alone. (…

POSSIBLE USE OF FERRUGINOUS TALCS IN STEATITE DIELECTRICS*
A bstract Several iron‐bearing tales were fired alone and in body form and were measured for shrinkage and absorption. Their colors were also noted. Electrical measurements of dielectric constant and loss characteristics were made on the bodies and compared with white‐firing tales. The effect of small additions of Fe…
