Inorganic–organic composite systems (e.g. see figure) with controlled electrical and optoelectronic properties are of current interest for applications including electrochromic displays, batteries, membranes, and sensors. The various methods of intercalation of the organic guests into the inorganic hosts, and the prop…

Abstract Molecular information expressed through molecular recognition events provides means for directing the spontaneous formation of supramolecular species from complementary components. It may allow the design and engineering of supramolecular materials, in particular of liquid crystalline and of polymeric nature.…

Thiosulfate ion was used as a substitute for hydrogen sulfide (H2S) to simulate stress corrosion cracking (SCC) of corrosion-resistant alloys (CRAs) and sulfide stress cracking (SSC) of high-strength, low-alloy steels. Several SCC tests using a variety of stress application techniques showed the brine containing thios…
Blends of conducting and insulating polymers (e.g. polypyrrole/PVC, see figure) offer distinct weight advantages over the materials, such as dispersions of carbon black or metallic powders in polymer matrices, traditionally used in microwave absorption applications. Polypyrrole, polyaniline, and polythiophene have bee…
We present a simple and accurate method of estimating the translational hydrodynamic friction on rigid Brownian particles of arbitrary shape. The Brownian friction coefficient f takes the form f=6\ensuremath{\pi}\ensuremath{\eta}${\mathit{C}}_{\mathrm{\ensuremath{\Omega}}}$, where ${\mathit{C}}_{\mathrm{\ensuremath{\O…
Diffusion coefficients for proteins in water are predicted. The numerical method developed is general enough to be applied to a wide range of protein surface shapes, from rodlike to globular. Results are presented for lysozyme and tobacco mosaic virus, and they are compared with actual data and with predictions made b…

Abstract The state of thermodynamic miscibility of a polymer blend and its resulting phase behavior and mechanical properties is largely determined by the balance between enthalpic and entropic contributions to the free energy of mixing. Recent applications of this thermodynamic consideration are reviewed for a variet…

A correlation exists between the width of the glass transition region measured using DTA or DSC during heating and the activation enthalpy Δ H η * for the shear viscosity of high‐Tginorganic glasses. This is demonstrated by the constancy of a dimensionless parameter C = (Δ H η * / R )(1/Tg – 1/Tg′), where Tg and Tg′ a…
This paper presents results of pseudopotential Hartree-Fock calculations on the titanium dioxide crystals. The optimized structures are in good agreement with experimental data. Both anatase and rutile structures have a large ionic character. The distortions from the undistorted crystals made of regular octahedra are…
Indium tin oxide (ITO) films deposited on single-crystal Si wafers by the electron-beam-(EB) evaporation method have been investigated by x-ray photoelectron spectroscopy (XPS) together with work-function and resistivity measurements. The XPS studies suggest that all the ITO films consist of crystalline and amorphous…

Abstract SBR compounds were filled with 17 carbon blacks covering the whole range of rubber grades and tested for bound-rubber content. It was found that the bound-rubber content of a polymer at high loadings is higher for large surface-area carbon blacks. On the other hand, the bound-rubber content per unit of interf…
