The theory of order and disorder, in the form used by Bragg and Williams, is extended to arbitrary composition of the constituent elements. The work is based upon the nearest neighbor interaction assumption of Bethe and the connection between the Bethe and Bragg-Williams theory is shown. In order to extend the Bragg-W…
An attempt is made to interpret the properties of alkali halide-thallium phosphors. The experimental basis of this interpretation is the work of Pohl and his numerous collaborators on these substances. It is concluded that the long wave-length absorption peaks of the phosphors which are not contained in the pure alkal…
Abstract The crystal structure of insulin is of interest not only in itself but as part of the wider problem of protein structure considered as a whole. The early X-ray work on protein fibres gave strong support to the original chemical theories of the existence of polypeptide chains as the essential backbone of the p…
A bstract Three definite conclusions can be drawn from the X‐ray diffraction studies of vitreous silica. (1) The tetrahedral scheme of coordination, in which each silicon is tetrahedral surrounded by four oxygens and each oxygen shared between two silicons, is given directly by the Fourier analysis. (2) The liquid‐lik…
Abstract The purpose of the present paper is to provide an experimental contribution towards the knowledge of the mechanism of crystal growth from solutions. Certain details about the mechanism of crystal growth have been studied in the case of one-component systems, i. e. crystals growing from the melt or from the va…

Abstract Der unvermeidbare Öffnungsfehler der Elektronenlinsen bewirkt, daß das theoretisch erreichbare Auflösungsvermögen des Elektronenmikroskops außer von der Wellenlänge auch von der Brennweite der Objektivlinse abhängt. Da dieser Brennweite aus Herstellungsgründen eine untere Grenze gesetzt ist, liegt die mit rau…

The problem of the potential distribution, current, and electron transit time resulting from the perpendicular injection of electrons into the space between parallel planes is considered. The electrons are assumed to be injected uniformly with velocities corresponding to the potential of the plane through which they a…
