Some Chemical and Physical Properties of Rubber
The chemical constitution and physical state of natural rubber in its viscous, high-elastic and crystalline conditions are described. It is shown that those depend on long hydro-carbon chains which are normally coiled and tangled. The high elasticity of rubber is made possible by the ability of the chains to straighte…

Influence of temperature on the adsorption of water vapor by collagen and leather
The adsorption of water vapor by co ll agen, commercial hide powder, and severa l leathe rs was determined at various relative humidities ranging from about 0 to 96 percent, at 28, 50, and 70 C. Determi nations were also made on chestnut a nd quebracho tann ins at 28 C at vari o us re lative humi dities. The results i…
Some Rare Earth Activated Phosphors
Two classes of rare earth activated phosphors having interesting and unusual properties are described. The first series, consisting of alkaline earth silicates activated by divalent europium, shows a wide range of fluorescent colors when excited by 3650 Å radiation. Some of these compounds are characterized by the sta…
Thermionic Work Function of the (100) Face of a Tungsten Single Crystal
A slab with one surface cut and etched parallel to (100) crystallographic planes formed the cathode in a low power electron microscope. The electron image of the cathode was formed on a fluorescent screen with a small hole at the center. An electron collector placed behind the hole permitted a measure of the electron…
2-MERCAPTOBENZIMIDAZOLE
The physical properties of 2-mercapto benzimidazole and main methods for its preparation are introduced.The situations of production and demand for 2-mercapto benzimidazole in China and in Japan are described in brief. Meanwhile,the application fields of 2-mercapto benzimidazole as rubber antioxidant and pharmacy inte…

Studies on the ecology of Zostera marina and Zostera nana (1)
The so-called “MOBA” or “Zostera-zone ” is a place of interest from the view-point of fishery in the inland sea. In Ikawazu-cove Zostera marina and Z. nana make “MOBA”, where the ecological studies on Zosterae has been carried out. In this paper the enviromental factors-hydrographycal and biological-which seem to corr…

Surface tension of regular solutions
The assumption of a unimolecular layer as the surface phase separating a strictly regular solution from its vapour phase, is in contradiction with the Gibbs adsorption formula. When, however, one takes into account the possible presence of two unimolecular layers inside the surface phase, it is shown that the composit…

Fractionnement par extraction du polythène
Abstract Les auteurs décrivent la technique d'extraction adoptée pour le fractionnement du polythène après avoir exposé les difficultés expérimentales d'une détermination des courbes de polydispersité de ce polymère d'après les méthodes classiques de précipitation. Les trois échantillons étudiés ont des poids molécula…

Sur la structure des solutions aqueuses de carboxymethylcellulose
Abstract Nous avons étudié deux carboxyméthylcelluloses ayant à peu près les mêmes caractéristiques moléculaires. Leur comportement rhéologique très différent s'explique par le fait qu'elles contiennent des proportions très différentes d'une fraction gonflant fortement dans l'eau mais insoluble. Cette fraction est par…
Effect of Adsorbed Polar Organic Compounds on Activity of Steel in Acid Solution
A series of aliphatic acids, amines, and esters, as well as one commercial corrosion inhibitor, were adsorbed from benzene solution onto SAE 1020 steel powder. These studies (reported elsewhere) showed that some portion of the sorbed material, depending on the compound, could not be desorbed by fresh solvent. The pres…
