Sawyer-Tower polarization (P-E) measurements have revealed dielectric hysteresis loops in antiferroelectric lead zirconate (PZ), suggestive of weak ferroelectric tendencies. Both polarization saturation and reemergence were observed which were on the order of 0.1 and 0.05 \ensuremath{\mu}C/${\mathrm{cm}}^{2}$, respect…

Previous work has shown that under mechanical deformation, three grades of polyethylene which differ mainly in terms of branch content exhibit two yield points. The first yield point occurs at low applied strains and marks the onset of temporary plastic deformation; the second yield point occurs at higher strains and…
<div class="htmlview paragraph">Effects of pilot injection on diesel combustion have been studied on a turbocharged direct-injection diesel engine. Under various engine operating injection conditions, emissions were measured while the pilot quantity and timing were varied. The result showed that the pilot inject…
Abstract Redox cycles are common in nature and likely have a profound effect on the behavior of soils and sediments. This study examined a key component of redox cycles in smectites, namely, the reoxidation process, which has received little attention compared to the reduction process. Unaltered (oxidized) and reoxidi…
3,4,5-tri-fluorobenzene derivatives with different core structures have been synthesized and their physical properties have been determined. Most of the compounds are nematic with broad existence regions. The materials have large dielectric anisotropy, low viscosity, low optical anisotropy and very good voltage holdin…
A series of tests was conducted on two carbon/epoxy systems to assess key factors in the characterization of the thermo-oxidative stability of composite materials. Mechanical properties (open hole compression strength, fracture toughness, and unidirectional compression strength) were determined from specimens aged in…
The phase ordering process following a quench to both the uniaxial and biaxial nematic phases of a quasi-two-dimensional nematic liquid crystal is investigated numerically. The time dependences of the correlation function, structure factor, energy density, and number densities of topological defects are computed. It i…

Alloy melts of the intermetallic compounds FeSi and CoSi were deeply undercooled using the melt fluxing technique. Crystal-growth velocities were measured as a function of undercooling by a high-speed photosensing infrared device. The experimental results were analyzed in the framework of dendrite growth theories with…

The development of new computer technologies designed to custom-fit apparel has created a need for quantification of apparel fit characteristics. Fit perception and preference data are needed to improve sizing for ready-to-wear and custom-fitted apparel. Tactile responses of subjects to the fit of pants were investiga…
Sol-gel processing has been widely employed for the fabrication of lead zirconate titanate (PZT) thin films. To successfully optimize thin film material properties for different applications, we must develop a fundamental understanding of the processing-property relationships inherent in the sol-gel fabrication proces…
Abstract A process for treating smectite-bearing rock samples that utilizes LR White resin; allows TEM observation of expanded smectite interlayers and therefore preservation of original rock textures. Examples of several lattice fringe images are shown, including: (1) Dioctahedral smectite layers from a shale (1388.9…
Summary Various formulations and methods of fabricating edible bilayer films consisting of wheat gluten as a structural layer and a thin lipid layer as a moisture barrier were investigated and examined for water vapour permeability. Solid lipids such as beeswax or paraffin wax deposited in a molten state onto the base…

The packing in molecular crystals is determined by intermolecular interactions. An understanding of these interactions would enable the design of systems exhibiting effective conductivity and superconductivity.
