THE CHEMICAL COMPOSITION, PHYSICAL PROPERTIES AND PRINCIPLES OF APPLICATION OF GLASS BEADS ARE REVIEWED. ALL THE PROPERTIES OF GLASS WHICH SIGNIFICANTLY AFFECT BEAD REFLECTORIZATION ARE DIRECTLY RELATED TO COMPOSITION. CHEMICAL DURABILITY AND SERVICEABILITY ARE NOT SYNONYMOUS TERMS IN DEFINING THE QUALITIES OF GLASS B…

The repulsive energy between layers of the graphite crystal has been calculated as an interaction of LCAO molecular orbitals in the layers. The van der Waals attractive term was found by setting the energy minimum to fall at 3.37A. When values of the effective nuclear charge and effective quantum number proposed by Ko…
In a paper to the Faraday Society (1946), Mering showed that the temperature to which one required to heat montmorillonite to produce irreversible collapse of the c-axis depended on the exchangeable cation. With Na-montmorillonite irreversibility began at about 550°C but with Ca-montmorillonite below 350°C During a st…
Thorium forms a tetragonal lower hydride of composition ThH{sub 2}. The hydrides ThH{sub 2}, ThD{sub 2} and ZrD{sub 2} have been studied by neutron diffraction in order that hydrogen positions could be determined. The hydrides are isomorphous, and have a deformed fluorite structure. Metal-hydrogen distances in thorium…

Abstract Studies were made of several clays of soils and other deposits to clarify the nature of weathering of layer silicates. Data obtained by X‐ray diffraction, thermal, R(OH)n sorption, and elemental analyses lead to the proposal of general occurrence of interstratified X‐amorphous zones in 2:1 layer silicates. As…
Abstract The high crystallite melting point of polyethylene terephthalate (Terylene) compared with the melting points of the aliphatic polyesters emphasizes the significance of the p ‐phenylene linkage as an important factor determining polymer properties. A consideration of other polymer structures containing the p ‐…
Après avoir rappelé l'existence et la théorie du traînage de fluctuations (ou traînage irréversible), l'auteur développe une théorie du traînage magnétique de diffusion (ou traînage réversible) selon laquelle les atomes étrangers interstitiels, qui sont à l'origine du phénomène, agiraient par couplage magnétocristalli…
