Etude sur les Oxydes de Thiouree. IV

J. Böéseken1948-01-01Recueil des Travaux Chimiques des Pays-Bas

Abstract La propriété fortement réductrice d'une solution ammoniacale du dioxyde de thiourée ne peut pas être attribuée à la formation passagère du sel d'ammonium de l'acide sulfoxylique, car les éthers éthyliques de cet acide, en solution alcaline, ne précipitent pas les sels de cadmium à l'état de cadmium métallique…

The crystal structure of glutaric and pimelic acid. Alternation of properties in the series of dicarboxylic acids

C. H. MacGillavry、G. Hoogschagen、F. L. J. Sixma1948-01-01Recueil des Travaux Chimiques des Pays-Bas

Abstract Glutaric acid and pimelic acid have analogous crystal structures. The CH 2 chains are stretched along the c‐axis, the plane of the zigzag is nearly parallel to (100). Packing of the COOH groups is practically identical to that in adipic acid. This packing enforces a torsion in the molecules of the odd acids a…

Diskrete Energieverluste mittelschneller Elektronen beim Durchgang durch dünne Folien

Gerhard Ruthemann1948-01-01Annalen der Physik

Mit der verschärften magnetischen Halbkreismethode hohen Auflösungsvermögens wurden die Energieverluste von 2 bis 8 ek Volt-Elektronen nach dem Durchgang durch sehr dünne Folien (100—500 ÅE Dicke) von Kollodium, Al2O3, Be, Al und Ag untersucht. Es ergab sich: 1 In den Geschwindigkeitsspektren fanden sich für jede Foli…

Elektronengasmodell zur quantitativen Deutung der Lichtabsorption von organischen Farbstoffen I

Hans Kuhn1948-01-01Helvetica Chimica Acta

Abstract Die Lage des Maximums der ersten (im Sichtbaren liegenden) Absorptionsbande von symmetrischen Cyaninfarbstoffen wird ermittelt unter Zugrundelegung eines Modells der Farbstoffmolekel, welches analog ist zu dem insbesondere von Sommerfeld als Modell für das Metall verwendeten Bild des freien Elektronengases.

Relation entre la constante d'anisotropie et la loi d'approche à la saturation des ferromagnétiques

Louis Néel1948-01-01Journal de physique

Quand le champ H croît, l'aimantation J d'un ferromagnétique cubique polycristallin tend vers la saturation Js selon la loi d'approche [FORMULE] et une théorie actuellement admise montre que b est égal à [FORMULE] où K est la constante d'anisotropie. L'auteur montre que cette théorie n'est pas correcte car elle a été…

Electrical Insulation Deterioration Treated as a Chemical Rate Phenomenon

T. W. Dakin1948-01-01OpenAlex

The basis is presented for a more accurate interpretation of the results of physical type tests to measure the thermal aging of insulation together with a more accurate method of applying the results of such tests to predicting insulation deterioration in practice. Since the observed physical changes during thermal ag…
