The critical behavior of charge-density waves (CDWs) in the pinned phase is studied for applied fields increasing toward the threshold field, using recently developed renormalization-group techniques and simulations of automaton models. Despite the existence of many metastable states in the pinned state of the CDW, th…

The constitutive equations based on polycrystalline models include information on the microstructure of the metallic materials and offer extended modelling capabilities with respect to macroscopic approaches. The purpose of this paper is to show that they can now be used in finite element calculations. The material is…
Abstract Complexation between pyridines and carboxylic acids is driven by hydrogen bonding. This simple, single hydrogen bond is shown to be capable of serving concomitantly as both the agent of liquid crystallinity and as the coupling bond generating an extended linear chain structure. Three such complexes made from…
The concept of interpolymer complexation is applied to develop a new method for interfacial modification of immiscible binary homopolymer blends. In this method, end-functional homopolymers terminated with acid and base groups are added to the blend to promote in situ end-complexation of the immiscible materials acros…
Time-resolved flash photography was used to investigate the dynamics of shock waves and cavitation bubbles generated by picosecond optical breakdown in bovine corneal tissue and water. A picosecond Nd:YLF laser was employed. A rapid decay of the shock waves was observed in both materials, with similar temporal charact…
Numerical solutions are obtained for a set of self-consistent-field equations that give the thickness dependence of the Helmholtz energy of a polymer film. Helmholtz energies are calculated for a series of polymer melts in order to illustrate some of the unique wetting behaviours that are exhibited by amorphous polyme…
The state and dispersion of Pt supported on mordenite have been studied using FTIR spectroscopy, CO Chemisorption, and H–D isotope exchange of cyclopentane. Under conditions for which other criteria indicate the presence of monatomic Pt0, a characteristic IR band of adsorbed CO is identified at 2123 cm–1. The position…

Bovine polymorphonuclear cells (PMNs) were found to migrate to suspensions of finely granulated chitin and chitosan of an average size of 1 μm at higher rates than to those of an average size of 30 and 50 μm, respectively, through a 5 μm pore size polycarbonate filter in a Blind well chamber.

New narrow bandgap polymers with bandgaps of 1.0–1.5 eV have been synthesized from the title monomers.
Four tetraaryl metalloporphyrin catalysts [FeIII, Ar = phenyl and pentafluorophenyl; FeIII and MnIII, Ar = 2,6-dichlorophenyl (FeIIITDCPP and MnIIITDCPP)] have been coordinatively bonded to poly(4-vinylpyridine), and imidazole modified polystyrene (PS-Im) and silica (Si-Im). Evidence is presented that suggests that th…
We examined the effect of ultrasound on the murine leukaemia L1210 cell line in culture, in the presence of porphyrins varying widely in their capacity to sensitize cells to light. These porphyrins enhanced ultrasound-induced cell damage in vitro only when present in the incubation medium. When cells containing intrac…
A method for predicting the elastic properties of textile-reinforced composites is presented with applications. The method is a modification of a Fabric Geometry Model (FGM) [1–3] that relates fiber architecture and material properties of textile-reinforced composites to its global stiffness matrix through micromechan…
Abstract Ultrasound can be used in chemistry to increase both reaction rates and yields of products. Most effects of ultrasound on chemical reactions are due to cavitation: the formation and collapse of small bubbles in the solvent. In this review, we first outline the physical background of cavitation, and discuss it…
A new type of self-assembled multilayer film, a molecular deposition (MD) film composed of meso-tetra(4-sulfenyl)porphyrin (tppS4) or copper phthalocyaninetetrasulfonic acid, tetrasodium salt (CuTsPc), alternating with a bipolar pyridine salt has been achieved and its structure studied in detail.
