Energy level data are given for the atom and all positive ions of silicon (Z=14). These data have been critically compiled, mainly from published material on measurements and analyses of the optical spectra. We have derived or recalculated the levels for a number of the ions. In addition to the level value in cm−1 and…

Abstract A critical review of the specification of orientation and its development in polymer‐processing operations is presented. Orientation may in general be specified by orientation distribution functions, but is most conveniently expressed in terms of orientation factors which are second moments of the distributio…
Lattice thermal resistivities of III–V compound alloys have been analyzed with a theoretical prediction based on a simplified model of the alloy-disorder scattering. The theoretical prediction shows a quite good agreement with the experimental data on various III–V ternary compounds. This model has also been applied t…
The electrical conductivity and Seebeck coefficients of La 1‐x Sr x FeO 3 ( x =0.1, 0.25) were measured as a function of oxygen partial pressure, P O2 , at T =900° to 1300°C. The electrical conduction was p type in the higher P O2 range, and n type in the lower P O2 range. The Seebeck coefficient indicated that the co…
Abstract Infrared absorption and polarized Raman spectra of rare‐earth titanates of pyrochlore structure Ln 2 Ti 2 O 7 (Ln = Sm, Gd, Yb; Y) and Ln 2 Sn 2 O 7 (Ln = La, Sm, Gd, Yb, Lu; Y) have been recorded. A valence force field calculation clearly supports the assignment of the frequencies. A comparison of the result…
Anodic oxidation of Ru and electrodes in has been investigated using x‐ray photoelectron spectroscopy. During evolution on Ru a highly defective hydrated oxide film is formed as a result of corrosion. At a temperature of 310°C in vacuum this film decomposes to metallic ruthenium. The surface of anodes prepared by ther…

The mechanical strength of most glasses and ceramics decreases with time under static loading in an ambient environment. This strength loss is associated with slow growth of preexisting surface flaws due to stress corrosion by water from the surrounding environment. We studied stress corrosion in vitreous silica expos…

At pH 5.4 apotransferrin (iron-free transferrin) binds to cell-surface transferrin receptors to the same extent and with the same affinity as does diferric transferrin at pH 7.0. Apotransferrin is quickly dissociated from its receptor when the pH is raised to 7.0. These and other results strongly support a simple mode…
Optical fibres consisting of Al2O3-SiO2 and Al2O3-P2O5-SiO2 cores have been fabricated by MCVD with a minimum attenuation of 0.7 dB/km at 1.6 μm. Both single-mode and multimode fibres were produced, the latter with a numerical aperture as high as 0.29. The tendency for Al2O3-SiO2 glasses produced by flame hydrolysis p…
Supercooled liquids and metallic glasses can be viewed as defected states of bond orientational order. Surfaces of constant negative curvature contain an irreducible density of point disclinations in a hexatic order parameter. Analogous defect lines in an icosahedral order parameter appear in three-dimensional flat sp…
Electrodynamic calculations of the electric field on the surface of large Ag prolate spheroids indicate that the field enhancement decreases rapidly, the resonance shifts to longer wavelengths and broadens, and a new set of higher-order resonances appears at shorter wavelengths. These results form the basis for compar…
Abstract The results of atomistic calculations of long-period tilt boundaries, which were reported in the preceding parts I and II, are generalized and represented concisely by using two-dimensional lattices, called decomposition lattices. The basis vectors of a decomposition lattice characterize the two fundamental s…
Abstract The results of the study of symmetrical tilt boundaries, reported in the preceding part I, are generalized to asymmetrical tilt boundaries. A classification of tilt boundaries in cubic crystals is developed that reveals which boundaries to choose in order to study equilibrium faceting or intrinsic grain bound…
