The thermal conductivity of oxide thin films deposited using dc, rf, and ion-beam sputtering is measured in the temperature range 80--400 K using the 3\ensuremath{\omega} method. Thermal conductivity data for amorphous thin films of ${\mathrm{SiO}}_{2}$ are nearly identical to bulk a-${\mathrm{SiO}}_{2}$. Data for amo…
Abstract The viscoelastic properties of amorphous polymers are reviewed with emphasis on the glass to rubber dispersion (often referred to as the transition zone). Deviations from thermorheologieal simplicity (where molecular retardation and relaxation mechanisms have the same temperature dependence) are identified. M…

PURPOSE: The purpose of our studies was to define the maximal-tolerated dose of liposomal doxorubicin (DOX-SL; Liposome Technology Inc, Menlo Park, CA), a doxorubicin formulation of polyethyleneglycol-coated liposomes, characterize the toxicities associated with this formulation, and evaluate any indication of antitum…
While thermodynamically stable metal oxides and other solids could be prepared by conventional high-temperature (ceramic) methods, syntheses of the more important metastable oxide materials of current interest, such as the zeolites and other microporous solids as well as layered and framework oxides of various kinds r…

Nanocrystalline particulate films , dispersions of nanoparticles in monolayers in which the inter‐particle distances can be controlled, and systems containing nanoparticles incorporated between the head groups of organic thin films (see Fig.) produced using a wet colloid‐chemical approach are reviewed. Size‐quantized…
A recurrent problem in materials science is the prediction of the percolation threshold of suspensions and composites containing complex-shaped constituents. We consider an idealized material built up from freely overlapping objects randomly placed in a matrix, and numerically compute the geometrical percolation thres…

First principles calculations of the electronic structure of trigonal iron were performed using density function theory. The results are used to predict lattice spacings, magnetic moments and elastic properties; these are in good agreement with experiment for both the bcc and fcc structures. We find however, that in e…
Polyisocyanates, long studied as theoretical models for wormlike chains in dilute solution and liquid crystals, differ from their biological helical analogs in the absence of a pre-determined helical sense. These polymers have an unusual sensitivity to chiral effects that arises from a structure in which alternating r…
Liquid crystals are promising materials for optical switching and image storage because of their high resolution and sensitivity. Azobenzene liquid crystals (LCs) have been developed, in which azobenzene moieties play roles as both mesogens and photosensitive chromophores. Azobenzene LC films showed a nematic phase in…
Spin-polarization is known to lead to important {\it magnetic} and {\it optical} effects in open-shell atoms and elemental solids, but has rarely been implicated in controlling {\it structural} selectivity in compounds and alloys. Here we show that spin-polarized electronic structure calculations are crucial for predi…
Ab initio molecular dynamics simulation is used to investigate the structure and dynamics of liquid Se at temperatures of 870 and 1370~K. The calculated static structure factor is in excellent agreement with experimental data. The calculated radial distribution function gives a mean coordination number close to 2, but…
Abstract The role of molecular weight distribution on the spinnability, structure, and properties of melt‐spun isotactic polypropylene filaments was studied with the aim of clearly distinguishing the effect of the breadth of the distribution from the effect of the average molecular weight and resin melt flow rate (MFR…
The composition, growth mechanism, and phases of carbon nitride thin films obtained from the reaction of laser ablated carbon and atomic nitrogen have been investigated. The nitrogen composition was found to increase to a limiting value of 50% as the fluence was decreased for laser ablation at both 532 nm and 248 nm.…
