The preparation of Ru and RuO 2 thin films by organometallic chemical vapor deposition and an investigation of the films' properties are reported. Ru is of interest for metallization in integrated circuit fabrication because its thermodynamically stable oxide, RuO 2 , also exhibits metallic conductivity. As a result,…
A systematic study of the inert‐strength characteristics of ceramics as a function of crack size relative to grain size has been made using controlled indentation flaws. The focus of the test program is on aluminas, with barium titanates and glass‐ceramics providing support data in confirmation of general trends. On p…
During reorganization of collagen gels by human skin fibroblasts the total protein content of the gels remained approximately constant. Only 5% of the collagen was degraded, although the volume of the gels decreased by 85% or more. It could be concluded, therefore, that gel reorganization required physical rearrangeme…
Oxidation of polyethylene with chromic acid/sulfuric acid generates a material (PE-CO2H) having a high density of carboxylic acid and ketone functionalities in a thin surface layer on the polymer. This paper determines the extent of ionization of the surface and near-surface carboxylic acid groups of these materials i…
A structural model of ZnO in the cumulant-expansion formalism has been studied with X-ray intensities measured on a spherical crystalat293 and,473 K. In the least-squares refinements, the thermal vibrations appear isotropic for both atomic species at the two temperatures investigated. The equivalent isotropic temperat…
The interaction of various alkenes with gold electrodes has been studied using surface-enhanced Raman spectroscopy (SERS). Large decreases, from 70 to 140/cm, were observed in the C-C double bond and C triple bond C stretching frequencies upon adsorption which are attributed to adsorbate-surface bonding involving thes…

A critical analysis is given of the EPR spectrum exhibited by the rare-earth S-state ions, Gd3+ and Eu2+, in glassy and disordered polycrystalline materials. The analysis of this spectrum and of its previous interpretations is based on (a) a set of criteria derived from a wide range of experimental EPR and optical dat…
The thermal response of a polymer composite material undergoing decomposition has been modeled. A one-dimensional transient thermal model with an n th order ap proximation for the rate of decomposition was applied. The model was tested by ex perimentally measuring the temperature profiles during decomposition for a gl…

The symmetry and stability of icosahedral incommensurate structures and generalized two-dimensional Penrose pentagonal structures are studied. The crystallographic properties of Penrose lattices are described by five-dimensional (5D) super space groups, and the icosahedral structures are described by 6D space groups,…
The viscosities of suspensions of sterically stabilized (hard) silica spheres in cyclohexane are reported as a function of shear rate (γ̇) and volume fraction (6×10−4<φ<0.6). The shear thinning scales according to (ηr−η∞)/(η0−η∞) =1/(1+1.31ηγ̇a3/kT) with limiting low and high shear viscosities described…
Starting from an exact expression for the Helmholtz free-energy functional of an inhomogeneous classical liquid, an approximate functional is presented which depends on a weighted average of the physical density. It retains the nonlocal character of the exact expression, but requires only the properties of the homogen…
The author reviews the present understanding of the electronic, geometric and chemisorption properties of metal oxide surfaces. It is restricted to experimental and theoretical studies of single-crystal oxide surfaces since only for those systems has it been possible to correlate surface properties with specific site…
Abstract The rate of oxygen permeation through La1−xSrxCo1−yFeyO3−δ was found to increase with an increase in Sr or Co content, showing that the permeability was mainly controlled by the amount of oxygen vacancies. The results obtained indicate that mixed conductive perovskite-type oxides are promising materials for o…
Data obtained in recent years on the epoxidising agents and the mechanism of their interaction with olefins are surveyed. Different types of hydroperoxides as well as certain short-lived epoxidising intermediates of the molecular and radical types functioning in situ are examined. The results of the stereospecific epo…
We present measurements and analysis of the basal thermal conductivity for two dichalcogenides: $1T$-Ta${\mathrm{S}}_{2}$ and $2H$-Ta${\mathrm{Se}}_{2}$. The data which are obtained for the first time cover the range 80-400 K. The lattice contribution is important for each compound and possesses specific features rela…
