Abstract The method for the evaluation of the percentage crystallinity in cellulose preparations from x‐ray intensity measurements, previously described in detail (J. Appl. Phys., in press) is reviewed briefly and new material presented consisting of crystallinity percentages between 8% and 70%. Cotton, flax, and rami…
Methods of correcting the systematic errors in electron-density maps due to using finite series of structure factors are discussed. Random errors in the maps are caused by experimental and computational rounding-off errors and by errors in the correction for finite series. Expressions are derived for the standard devi…

Abstract A calculation of the maximum shear strain under which a two-dimensional close-packed lattice is stable has been carried out in terms of the forces between the lattice components. Two types of force were used; those between floating bubbles, which enabled a comparison with experiments on actual rafts of bubble…
Abstract A quantitative study of the mechanical properties of two-dimensional bubble rafts has been made. The elastic properties have been used to check the theory of the interaction of the bubbles, and reasonable agreement is obtained. The plastic properties are the main subject of this paper. Plastic deformation pro…
The thermal conductivity of glasses decreases with decreasing temperature, while the conductivity of crystalline substances increases with decreasing temperature. The behavior of glasses is interpreted in terms of an approximately constant free path for the lattice phonons, so that the conductivity decreases roughly w…
The compounds Ce2S3, La2S3, Pu2S3, Ac2S3 and Am2S3 are shown to be iso-structural. The structure is cubic with sixteen sulfur atoms and 10⅔ metal atoms per unit cube. The unit-cell constant for the prototypic compound Ce2S3 is a = 8.6173 ± 0.0005 kX. The metal atoms are randomly distributed over twelve-fold positions…
