Über die Reduktion von Chromoxyd mit Wasserstoff und festem Kohlenstoff
Abstract Es wurden Reduktionsversuche an Chromoxyd und Chromoxyd ‐Eisen‐Gemischen mit Wasserstoff und festem Kohlenstoff durchgeführt. Der praktische Reduktionsbeginn wurde bei der Reduktion mittels Wasserstoff und Kohlenstoff fur reines Chromoxyd zu etwa 1000°C gefunden, wahrend er bei Gegenwart von Eisen um etwa 150…

An improved apparatus for measuring the thermal transmission of textiles
An apparatus is described for measuring the thermal transmission of textiles. A horizontal plate is heated electrically and maintained at a constant temperature by means of a thermostat. The plate is surrounded by a guard plate which is also maintained at the same temperature to prevent lateral flow of heat into or ou…

Spontaneous emulsification, and reactions overshooting equilibrium
Abstract Spontaneous emulsification was discovered in 1878 by Johannes Gad (1878). He observed that when an oil containing fatty acid is placed quietly upon an alkaline solution with avoidance of stirring, streamers shoot out which at their ends disintegrate into minute droplets forming a milky emulsion. In the follow…

The Crystal Structure of Potassium Metaborate, K3(B3O6)
In order to find the configuration of the metaborate group the crystal structure of potassium metaborate was determined. The crystals are rhombohedral ar = 7.76A, α = 110° 36′ with six molecules KBO2. The density is 2.348. The space group is R3̄c(D3d6). All atoms are lying on twofold axes at positions: ±(u, ½—u, ¼) ↺…
Oxygen Production by the Diatom Coscinodiscus Excentricus Ehr. in Relation to Submarine Illumination in the English Channel
1. A method, due to Poole & Atkins, is described for computing the total available energy at any depth in the sea, in joules or g.-cal. 2. The oxygen production of pure cultures of the diatom Coscinodiscus excentricus Ehr. was measured by the Winkler method after exposure of the diatoms in bottles at known depths…

X-ray analysis of the dibenzyl series IV—detailed structure of stilbene
Abstract A preliminary account of the crystal structure of stilbene in relation to other compounds in the dibenzyl series has already been given in Part III of this work (Robertson, Prasad and Woodward 1936). The general arrangement of the four molecules in the unit cell was deduced from certain absolute intensity mea…

The Dielectric Properties of Insulating Materials
This paper gives a qualitative account of the way in which dielectric constant and absorption data have been interpreted in terms of the physical and chemical structure of materials. The dielectric behavior of materials is determined by the nature of the polarizations which an impressed field induces in them. The vari…
