We demonstrate an improvement in the operating temperature of a quantum dot-in-a-well (DWELL)-based infrared photodetector with spectral response observable till 250 K. This improvement was achieved through engineering the dot geometry and the quantum confinement via postgrowth capping of the quantum dots (QDs) by sel…
Pulsed electric field (PEF) treatment has been proposed as a decontamination method for labile matrices used in tissue engineering applications. Through the application of PEF, a non-thermal treatment that causes bacterial inactivation through the irreversible rupture of microbial cell membranes, inactivation is achie…
The limits of the applicability of the Polarised Infrared (Fourier transform infrared) spectroscopy technique, which is used to measure the order parameters of biaxial liquid crystals, is investigated in detail for different experimental geometries and cell thicknesses. General expressions for the transmittance of the…
The gap narrowing in charged ${\text{Si}}_{35}{\text{H}}_{36}$ and $n$-type doped ${\text{Si}}_{34}D{\text{H}}_{36}$ ($D=\text{P}$, As, Sb, S, Se, and Te) clusters is studied within the GW approximation, including energy dependence of the dielectric matrix and local-field effects. It is shown that the density function…
This paper proposed the optimal rotor bar design of the permanent split capacitor (PSC) single-phase induction motor. The starting torque and motor efficiency were used as parameters for optimization. The Taguchi method was used in experimental designs for optimization of multiple parameters and the finite element met…
Flux-switching motor (FSM) offers unique advantages of low cost, high power density, relative low level vibration and acoustic noise. In this paper, a nonlinear equivalent magnetic circuit model (MCM) was developed to analyze the electromagnetic performance of Flux switching motor. Due to the obvious marginal and loca…
Abstract To investigate the stretching effect of polymer‐based composites, the films of polyvinylidene fluoride (PVDF) and nickel (Ni) composites were stretched at 120°C. It was found there was an abrupt increase in dielectric constants and conductivities with stretching ratio (SR). In comparison to percolation effect…
Discrete core-shell hybrid nanoparticles comprising individual met-myoglobin (met-Mb) molecules incarcerated within an ultrathin polymer/silica shell were prepared without loss of biofunctionality by a facile self-assembly procedure. Solubilisation of met-Mb in cyclohexane in the near-absence of water was achieved by…
Poly(amic acid) (PAA) derived from ethylenediaminetetracetic dianhydride shows great potential as a biomaterial suitable for biomedical applications. To evaluate this polymer class further, in vitro cell toxicity (WST-1/ECS, ELISA based) and cell compatibility (cell adhesion and cell proliferation) tests were conducte…
Components of dental composites have been implicated as metabolic and oxidative stressors in cells. Antioxidant colloidal platinum nanoparticles (CPtN) could be useful as nanofillers that reduce cellular stress caused during placement and exposure to unpolymerized composite components. Yet, CPtN may have pro- or anti-…
This paper investigates the development rate of poly(methyl methacrylate) (PMMA) after it is exposed to synchrotron x-ray radiation. The x-ray exposures were performed at both Synchrotron Radiation Center and Brookhaven National Laboratories. The development rate of PMMA in a variety of developers was measured as a fu…
This paper deals with the shape optimization of the BLAC motor, in order to reduce its cogging torque. The motor type is an interior permanent magnet motor, and the motor is designed for an electric power steering system application. In this application, a motor cogging torque is one of the most important parameter, a…
Abstract Supramolecular crosslinking was studied in reversible loose‐fit rotaxanation between a size‐mismatched ring and a dumbbell‐shaped chain attached to bulky terminals through slipping of the crosslinked rings onto the chain using a combination of β‐cyclodextrin (β‐CD) and poly(ethylene glycol) (PEG) in water. Th…
PURPOSE: To clarify the role of p53 in boron neutron capture therapy (BNCT) for oral squamous cell carcinoma (SCC), the effect of BNCT on oral SCC xenografts with either wild-type or mutant-type p53 was examined. MATERIALS AND METHODS: Oral SCC cells expressing either wild-type (SAS/neo) or mutant-type p53 (SAS/mp53)…
Revised electron impact differential cross section (DCS) for excitation of the four levels comprising the 3p54s configuration of argon and their sum are reported for incident electron energies of 12.5, 13.0, 14.0, 14.5, 15.0, 15.5, 15.76, 16.0, 16.75, 17.5 and 20 eV. These cross sections were obtained using two conven…
Abstract The effect of reprocessing two mixtures: recycled high impact polystyrene (HIPS) with polybutadiene (PB); and HIPS with styrene‐ethylene‐butylene‐styrene (SEBS) have been studied in this article. To simulate recycled HIPS, we reprocessed virgin HIPS through five cycles. The virgin HIPS, the recycled HIPS, and…
Abstract This study reports the synthesis and characterization of the star‐shape poly(acrylic acid)s with different arm numbers and molecular weight (MW)s. The effects of arm number and initiator concentration on the atom‐transfer radical polymerization reaction kinetics and solution viscosity were studied. The effect…
Abstract Peroxide crosslinkable ethylene–propylene–diene monomer (EPDM) compounds are formulated systems in which the base polymer generally comprises only a small fraction of the total composition. Knowledge of the intercomponent dependency is therefore crucial for successful product development. In this study, we ha…
The Josephson effect between LaPt 3 Si and Al has been investigated for junctions on the (100) and (001) faces of LaPt 3 Si single crystals and a polycrystal. In the magnetic-field dependence of the Josephson critical current, the anomaly previously reported for CePt 3 Si appeared; an oscillating pattern without a dom…
This paper deals with a method for reduction of eddy current loss in permanent magnet for high power in-wheel type motor applicable to electric vehicle traction. The In-Wheel type motor was built before this paper written. However, it has a problem of eddy current loss in permanent magnet. Therefore, this paper presen…
