The monoclinic 0-phase in the chromium-aluminium system has been shown to be isomorphous with a'(V-A1). The structure has been refined and the interatomic distances are discussed and compared with those in a'(V-A1) and with those in two ternary alloy phases containing chromium and aluminium.
Residual electrical resistivity has been used as an index of the damage present in tungsten irradiated in a nuclear reactor at 4°K and 77°K. A comparison was made between four different types of specimen prepared from cold-drawn wire respectively annealed before irradiation at 2000, 1500, 800°c and not at all. A fifth…

Abstract Although the process of dolomitization is not well known at present, the requirement of conservation of mass of the chemical constituents of the rock and the interstitial solution places definite limits on the process. Most subsurface waters contain relatively small concentrations of bicarbonate compared to t…

Diffusion in a polycrystalline body is discussed under the assumption that two interrelated mechanisms consisting of diffusion through the grains and in the boundaries around the grains are dominant in different penetration regions. The general behavior of the average concentration-distribution of diffusant is describ…
Abstract The infrared spectra of doubly oriented films of mercerized ramie and Fortisan crystallites were observed over the 650–3600 cm. −1 frequency range. Polarization properties of the bands were determined. The CH 2 symmetric bending frequency was found to be parallel polarized, from which it was concluded that th…

Abstract The polarized infrared spectra of crab chitin crystallites, blowfly larval cuticle, lobster tendon, and partially deacetylated lobster chitin have been studied. In addition, the spectra of amorphous deacetylated chitin, deuterated lobster chitin and crystalline N ‐acetylated chitohexaose were obtained and ana…
Fe+ + + and Fe+ + ions in glass have been studied by means of paramagnetic resonance. The correlation of the Fe+ + + concentration with an intense resonance at g=4.27 shows the resonance is due to Fe+ + +. A theory is proposed explaining the observed g value and the implications for the atomic surroundings of Fe+ + +…
Abstract The flow of lead of different purities under conditions of simple shear has been investigated over a wide range of strain, at different stresses, and mostly at a temperature in the neighbourhood of 27 °C. The phenomena have been studied both with unchanged direction of stress and with the direction of stress…
Abstract Type I aluminium films deposited at 0 °C were of relatively low area, ca. 1000 cm2, stable and with a certain porosity since CO uptake was proportional to film weight. Thus a film area could be determined from its weight, since at saturation CO molecules occupy 0·75 of the total surface area given by the B.E.…
