ABSTRACT Clothing movement was evaluated on a video screen by a descriptive analysis sensory technique and correlated to tactile attributes and fabric mechanical properties. Six fabrics were tailored into identical wide‐leg trousers and dresses, animated by a professional model, filmed and edited for sensory evaluatio…
Radiation damage and the recrystallization of natural titanite (CaTiSiO 5 ) were studied using infrared spectroscopy in the spectral range from 50 to 7500 cm -1 . The results show that radiation damage leads to systematic changes in spectral features: decreasing absorption and reflectivity, line broadening, and loss o…
This paper presents the synthesis of 1-13C- and 4-13C-plastoquinone-9 and their characterization with NMR spectroscopy and mass spectrometry. The synthetic scheme has been further adapted to introduce 13C-labeled plastoquinones on all individual and on each combination of positions in the quinone ring. Also a two-step…
Abstract Phosphorylation of cellulose flame retarded with an ammonia‐cured, polycondensed tetrakis(hydroxymethyl) phosphonium‐urea derivative (as Proban CC, Rhodia) with a polyol diphosphoryl chloride or phosphorochloridate like spirocyclic pentaerythritol di(phosphoryl chloride) or diphosphorochloridate, SPDPC can yi…
The rheological behavior of a low‐toxicity, aqueous, Al 2 O 3 –chitosan–2,5‐dimethoxy‐2,5‐dihydrofuran (DHF) system was examined over a temperature range of 20°–98°C. At room temperature, a high‐volume‐fraction solids, shear‐thinning suspension was produced. The suspension remained in a liquidlike state for ∼24 h. By…
Here we present a comparison between protein fragments produced by limited proteolysis and those identified by computational cutting based on the building block folding model. The principles upon which the two methods are based are different. Limited proteolysis of natively folded proteins occurs at flexible sites and…
This article reviews the valence band (VB) electronic structure of carbon nitride and reports on results obtained from carbon nitride films prepared by pulsed laser deposition (PLD). In the present work, two series of carbon nitride films have been synthesized by nitrogen-ion-beam-assisted PLD and reactive PLD in nitr…
Abstract The development of the new high‐modulus and high‐strength fibre M5, made of poly{2,6‐diimidazo[4,5‐b: 4′,5′ ‐e]‐pyridinylene‐1,4(2,5‐dihydroxy)phenylene} or PIPD, has resulted in an organic polymer fibre with exceptional fire protection properties when compared with PBO, Twaron, Kevlar and Nomex fibres. The P…
Imogolite is one of the aluminosilicates with a chemical formula of Al 2 O 3 SiO 2 (H 2 O) n , consisting of hollow nanotubes with an external diameter of about 2.5 nm and a length from several hundred nanometers to a micrometer. Atomic force microscopic (AFM) observation revealed that the imogolite molecules form a f…
Synthesis of Ce 0.9 Gd 0.1 O 1.95 (CGO) powder from a polymeric precursor solution containing a mixture of nitrates, nitric acid, and ethylene glycol was investigated with emphasis on the effect of polymerization of the precursor solution on the crystallization and morphology of the derived solid intermediate and the…
Basso and Bertotti's physics-based, yet simple, static hysteresis model is brought to the power electronic community as an alternative for simulation of magnetic components embedded in a power electronic converter. The model is reviewed and its equations cast in application/simulation-oriented forms. It is then revise…
Temperature dependence of interdiffusion coefficient of In–Sn was measured by a capillary method under a static magnetic field. The obtained diffusion coefficient data agreed well with data measured in microgravity environment at a lower temperature range. The application of static magnetic field could be a good subst…
We present a kinetic model to explain irradiation-induced phenomena in graphite up to a high dose of amorphization. We attribute the origin of amorphization to the accumulation of dislocation dipoles instead of a disordered region assumed in a previous model by Niwase. Calculated results for the change in a sample dim…
Moldable nonwoven fabrics for automotive applications make up a large market, but they are currently made from synthetic fibers that are not easily biodegraded. Incorpo rating kenaf fibers into automotive nonwovens may enhance their biodegradability, while imparting improved acoustical insulation and reducing vehicle…
Abstract Oxygen containing chemical groups on the carbon black surface can react with the carboxyl groups of XNBR, or epoxy groups of ENR, or chlorosulfonated groups of CSM, during high temperature molding of the rubber-filler mixtures. This leads to crosslinking of the rubber phase. The extent of crosslinking increas…
A detailed kinetic analysis has been performed of the thermoluminescence (TL) glow curve of high purity synthetic quartz. The kinetic parameters of the glow peak at 110 degrees C were evaluated for doses ranging from 0.1 Gy to 100 Gy using glow curve deconvolution (GCD), initial rise, variable heating ratc and phospho…
The interaction between low-k organosilicate glass (OSG) and photoresist removal is investigated. O2 plasma ashing and chemical wet stripper are commonly performed to remove photoresist (PR) in integrated circuit fabrication. However, O2 plasma or wet stripper will attack function groups and cause Si–OH group formatio…
We present theoretical modeling and experimental validation of both capacitive (dot) and inductive (hole) metallic crossed gratings in the mid-infrared (2-5 microm). The gratings are fabricated by use of interferometric lithography and modeled by use of rigorous coupled-wave analysis. Our experimental and numerical in…
Abstract Supercritical fluid extraction has been carried out on as‐synthesized Si‐MCM‐41 in a study to evaluate the efficiency of SFE in the recovery of the organic template cetyltrimethylammonium hydroxide (CTMAOH) from the pores of Si‐MCM‐41. Effects of different extraction parameters on the extraction efficiencies…
We have developed fast numerical solutions to the diffraction of light from periodic array structures that allow real-time regression fitting to optical data. In contrast to previous publications, the solutions we have developed are easily applied to focused beams with arbitrary angles of incidence on periodic structu…
