New data concerning the mechanism of photodissolution of metals in vitreous semiconductors are reported. These data give evidence that (1) for the photodissolution to occur the light must be absorbed in the vicinity of the doped/undoped chalcogenide interface, (2) the processes at the doped/undoped chalcogenide interf…
Measurement of the magnetostriction constant of amorphous wire by conventional techniques is very difficult because of its small diameter. However, accurate determination of the magnetostriction constant is important in the study of amorphous wires. Here the saturation magnetostriction constant (λs) for a low-magnetos…
Abstract Ferrocene and its alkyl-substituted derivatives intercalate into the lamellar VOPO4 compound, where the ferrocenium and related cation species are located in the interlayer space of the V(IV)/V(V) moieties. Based on powder X-ray diffraction patterns and ESR spectra, arrangements of the cations and electronic…
The late stages of phase separation/gelation in concentrated solutions of poly(γ-benzyl-α, L-glutamate) in N,N-dimethylformamide containing 2% added water have been observed by video optical microscopy. Microscopic phase separation is directly evident on cooling homogeneous, isotropic solutions. Within the phase separ…
Thin polycrystalline films of hexatriacontane (HTC) were irradiated with low energy (E=0.5–15 eV) electrons, and off-specular backscattered electron spectra were measured. Below E∼7 eV, single and multiple vibrational excitations only are observed, which relax the electrons down to the bottom of the HTC conduction ban…
We present a high‐resolution low‐energy electron diffraction study of the clean Pt(110) reconstructed (1×2) to (1×1) phase transition and its critical phenomena. The phase transition is shown to be a continuous order–disorder type with critical temperature Tc∼960 K. The critical exponents β, γ and ν extracted from the…
Vanadium dioxide thin films were deposited by radio-frequency (rf) reactive sputtering. An in situ anneal was found to improve stoichiometry, alter optical contrast, and increase grain size for a set of films. Biasing of a second set of substrates during deposition was found to increase the infrared (IR) transmission…
The small-angle magnetization rotation method has been shown to be applicable for measuring the saturation magnetostriction of amorphous wires by using the circumferential field generated by an ac current through the wire. The method was used to measure compositional variation of magnetostriction of Fe-Co based amorph…
Variable takeoff angle x-ray photoelectron spectroscopy was used to determine the surface composition of five polyurethane block copolymers. The high-resolution C1s spectra from all five polyurethane samples had peaks at binding energies of 285.0, 286.5, and 289.5 eV, which are consistent with the presence of hydrocar…
In order to study the effect of the potential well on the single ion dynamics and the charge transport in molten LiNO3, a molecular dynamics simulation, which included all degrees of freedom of vibrating nitrate ions, was carried out. Simple Coulomb pair potential with Born-type repulsion was adopted as a standard, an…
A direct electron optical study has been made of anodic film growth on substrates comprising a tantalum layer superimposed on aluminium and the reverse situation (i.e. an aluminium layer superimposed on tantalum). To achieve the latter, the system comprised an ion-plated aluminium layer superimposed above a tantalum l…
The recent interest in diamond-like carbon (DLC) and its special properties and applications has resulted in attempts to deposit such films at greater rates and over larger areas. It is necessary that the new methods retain the special properties of the DLC material. The purity and structure of the films will be discu…

Bismuth is an effective promoter in formic acid electrocatalysis on Pt(100), yet this system is problematic and the reaction mechanisms not well understood. We investigate this from a surface science perspective by studying Bi adsorption and coadsorption with CO, O2, H2O, and HCOOH on Pt(100) with low-energy electron…
Abstract The utilization of network structure to impart stable orientation to a rubbery material has been largely unexploited to date. It is demonstrated that the presence of a double network will amplify both the modulus and strain crystallizability of an elastomer, presumably without the disadvantages encountered in…
