According to Bikerman, who attributes failure in adhints to a weak boundary layer, it is almost impossible and meaningless to correlate adhesive strength to surface-chemical properties of adhints. Though his assertion seems to be confirmed by the recent studies of Schonhorn and his coworkers on the methods of CASING a…
The transformations produced by quenching from the equilibrium β-phase region have been studied in a range of titanium alloys with 5·8-53 w/o tantalum. The martensitic phase is h.c.p. (α′) with up to 22 w/o Ta, and orthorhombic (α″) with 23-53 w/o Ta. In alloys with up to 32 w/o Ta, the product is finely twinned on {1…
Models for low-spin-high-spin transitions in transition-metal-ion compounds are presented. Within a molecular-field scheme, the transition between, and coexistence of, high-spin (Hund's-rule) and low-spin (crystal field) states are described. One- and two-sublattice-spin structures and the influence of magnetic intera…

The presence of a conductive plane near a thin magnetic film perturbs the propagation of a surface magnetostatic wave. This paper treats the case of a dielectric layered structure, and an expression for the characteristic dispersion is derived. The dispersion is unique with respect to magnetostatic propagation in that…
The lattice parameters of BiFeO3 were determined with the Straumanis method. At 25–13±0.02 °C, the hexagonal parameters are ah = 5.5799±0.0003, and ch = 13.8670±0.0005 Å. The temperature dependence of the lattice parameters in the range 20–325 °C is given by the equations: ah = 5.5764 Å + 6.06 × 10−5t, and ch = 13.862…
A complete molecular-orbital energy-level diagram for Ti${\mathrm{O}}_{2}$ is empirically deduced from the combined $\mathrm{Ti}{L}_{\mathrm{III}}$, $\mathrm{Ti}K$, and $\mathrm{O}K$ x-ray emission and absorption band spectra. All of the occupied and vacant orbitals within 25 eV of ${E}_{F}$ are located on a relative…
Room temperature infrared absorption spectra in the range 4000–250 cm−1 of binary borosilicate thin glass films deposited by reacting argon-diluted SiH4–B2H6–O2 mixtures on heated silicon substrates at 300–400°C have been obtained throughout the composition range. Spectra of the end components are found to be in good…
The relative permeability of sodium channels to eight metal cations is studied in myelinated nerve fibers. Ionic currents under voltage-clamp conditions are measured in Na-free solutions containing the test ion. Measured reversal potentials and the Goldman equation are used to calculate the permeability sequence: Na(+…
It is shown that the random network theory of glass structure accounts satisfactorily for the observed x-ray and neutron radial distribution functions of vitreous silica, out to interatomic distances of at least 0·8 nm (8 Å). This result is based on the study of a molecular model containing sample atomic arrangements…

Electron Microscope Study of Pyramidal Slip {112} 〈113〉 in Magnesium We have investigated {112} 〈113〉 pyramidal slip in magnesium whose CRSS exhibits an anomalous dependence on temperature and increases between 270 and 375 K. Typical dislocation configurations were investigated by TEM in various temperature ranges. A…
