Abstract In a previous communication, Topley and Hume described the results obtained in an experimental study of the decomposition of calcium carbonate hexahydrate and showed that they could be most reasonably explained by assuming that reaction occurred only at the interface separating the two solid phases, CaCO3. 6H…

Abstract 1. Es wurde ein System von 3 Metallen gesucht, von denen zwei gegenseitig praktisch unmischbar sind, während das dritte sich in den beiden anderen bis zu hohen Konzentrationen auflöst, ohne daß deren gegenseitige Löslichkeit durch diesen Zusatz wesentlich gesteigert wird. Mischungen von Aluminium, Silber und…
Abstract 1. Es wurden folgende Doppelcarbonate dargestellt und einige ihrer physikalischen Konstanten bestimmt: Sämtliche Körper sind optisch negativ und gehören den hexagonalen bzw. trigonalen Kristallsystemen an.

By the aid of the hypergeometric function with two variables, the transition probability in the sense of the quantum mechanics between two states with positive energy in a central field due to nuclear charge $\mathrm{Ne}$ has been calculated. When the transition probability calculated is applied to the intensity of co…
These experiments show that the changes in magnetization which take place suddenly in large groups of atoms account quantitatively for the whole change in magnetization which corresponds to the steeper part of the hysteresis loop. Since it is estimated that discontinuities corresponding to groups of ${10}^{10}$ atoms…

Further studies on the isometric form of hydrated tricalcium aluminate are reported. These include methods of preparation, crystalline forms, X-ray diffraction pattern, and determinations of solubility and density. The products formed when the hexagonal form of hydrated tricalcium aluminate is dehydrated at definite v…

ABSTRACT The volatility of selenium in making selenium ruby glass has been studied. About 75% of the selenium added to the batch was lost by volatilization. Sodium selenite and barium selenite were stable at 950°C and are probably stable at higher temperatures. Regardless of whether selenium or the compounds studied a…
In magnetic analysis of electronic velocities the plane containing the receiving slit is placed at the angle ${\ensuremath{\Phi}}_{m}=180\ifmmode^\circ\else\textdegree\fi{}$ to the plane containing the entrance slit. The "resolution," at ${\ensuremath{\Phi}}_{m}$, between two electrons of velocities $V$ and $v$ both e…

Recent investigations of magnetic properties of alloys of iron, nickel and cobalt have resulted in the discovery of materials of remarkable magnetic properties previously unknown. In a brief review, early experiments that led to the discovery of these materials and the magnetic properties of the entire field are discu…
