The Interlayer Binding in Graphite
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…
Irreversible Dehydration in Montmorillonite
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…
The crystal structure of thorium and zirconium dihydrides by X-ray and neutron diffraction
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…

Weathering Sequence of Clay‐size Minerals in Soils and Sediments
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…
The p‐phenylene linkage in linear high polymers: Some structure–property relationships
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 ‐…
Théorie du traînage magnétique de diffusion
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…

On the generation of vacancies by moving dislocations
New experiments of Molenaar and Aarts, Blewitt and others seem to confirm the view of the author, previously based only on the experiments of Gyulai and Hartly and Stepanow on sodium chloride, that vacant lattice sites, and possibly interstitial atoms, are generated during plastic flow in ductile crystals, particularl…
Failure and Fracture of Metals as Nucleation Processes
The discontinuous phenomena in plasticity of metals, such as the yielding, the state of ultimate strength and the brittle fracture, were regarded as a kind of Markoff process, and studied from the standpoint of nucleation theory. The fundamental features of these types of failures, namely, (1) the relation between str…
