Abstract This paper describes an experimental technique to evaluate the stress distribution around an automotive windscreen ‘chip’, which is created by projectile impact. This stress distribution is measured before and after a typical resin injection repair procedure, and the results indicate a significant reduction i…
Abstract Five families of new controlled epoxy thermosets (CENs) using three monophenol chain terminators were prepared to study systematic changes in the structure and amount of the monophenol and the initial molecular weight between crosslinks (Mc,i) on the properties of epoxy thermosets. Glass transition temperatur…
Abstract ZnO was deposited on Corning glass using an equimolar aqueous solution of zinc nitrate hexahydrate and hexamethylenetetramine by Aqueous Chemical Growth. The morphological characteristics of the as‐grown ZnO structures can be varied by adjusting the precursor solution concentration and solution temperature. A…
X-ray diffraction measurements have been made on a series of molecular beam epitaxy (MBE)-grown ${\text{RT}}_{2}$, ${\text{RT}}_{3}$, ${\text{RT}}_{5}$, and ${\text{R}}_{2}{\text{T}}_{17}$ thin layer samples, where $\text{R}=\text{Er},\text{Nd}$, and $\text{T}=\text{Co},\phantom{\rule{0.3em}{0ex}}\text{Fe}$, and ${\te…
UNLABELLED: The aim of this study was to investigate the effect of depsipeptide on the in vitro transfection efficiency of PEI/DNA complexes. MATERIALS AND METHODS: PEI (polyethylenimine 25K) formed a complex with pcDNA3-CMV-Luc and was investigated for its transfection efficiency in KB human oral carcinoma and Raji h…
The near band edge emissions of an individual ZnO nanobelt were investigated by cathodoluminescence spectroscopy, which has unique advantages in higher spatial resolution, orientation, and environmental independence over the conventional photoluminescence spectroscopy. The results show that the presence of a large sur…
The performance of three bidirectional modal methods the "classical" bidirectional eigenmode expansion propagation method, the aperiodic rigorous coupled wave analysis (known also as the Fourier modal method), and the mode expansion method based on harmonic expansion are mutually compared using modeling tasks that inc…
This paper investigates the use of plasmonic optical waveguides in superconductive traveling-wave photodetectors (STWPDs) as a promising technique to efficiently couple the input optical field into the superconducting detecting structures. Field analysis is employed to study the propagation of the light through the in…

Abstract Indium tin oxide (ITO) thin films were deposited onto flexible polyimide substrates using RF sputtering system at room temperature. The deposited films were then heat treated at different temperatures in air and vacuum atmospheres. The structural variations and as consequence the electro‐optical characteristi…
We report a foaming-polymerization method to prepare stable polyaniline (PANI)/polyvinyl alcohol (PVA) foams. The formation mechanism of the foam materials is investigated and the photoelectric conversion properties of PANI/PVA foams are studied in detail. The enhancement of photoelectric conversion behavior in foams…
We calculated the current distribution in a coated conductor (CC) from magnetic induction profiles measured using the scanning Hall probe method. An external magnetic field was applied in the normal direction with respect to the tape surface and was decreased stepwise from H peak to − H peak . From the hysteretic beha…
Using computational modeling, we simulate the fluid-driven motion of microcapsules on patterned surfaces to establish guidelines for creating simple microfluidic devices for bioassays and multistage chemical reactions. The microcapsules, which consist of an elastic shell and an encapsulated fluid, model biological cel…
We analyze the density of state (DOS) and a nonmagnetic impurity effect in electron-doped cuprates starting from two different scenarios: the ${d}_{{x}^{2}\ensuremath{-}{y}^{2}}$-wave superconductivity coexisting with antiferromagnetic spin density wave (SDW) order versus ${d}_{{x}^{2}\ensuremath{-}{y}^{2}}$-wave supe…
A novel multifunctional inorganic−organic photorefractive (PR) poly( N -vinyl)-3-[ p -nitrophenylazo]carbazolyl-CdS nanocomposites with different molar ratios of CdS to poly( N -vinyl)-3-[ p -nitrophenylazo]carbazolyl (PVNPAK) were synthesized via a postazo-coupling reaction and chemically hybridized approach, respect…
Emollients are an essential treatment option for the reduction of dry skin conditions and the maintenance of healthy skin. These functions are dependent on complex interactions within the upper layers of the epidermis, designed to maintain the skin's dynamic but intact barrier function. Choice of emollient is dependen…
To avoid the commonly required regrowth steps in conventional distributed feedback laser fabrication, laterally-coupled distributed feedback (LC-DFB) lasers lithographically pattern the grating out of the ridge waveguide. Using higher order gratings increases the lithographic tolerances, resulting in lasers that are m…
Abstract Vinylester resin (VER) composed of bisphenol‐A‐based epoxy methacrylate and styrene was cured finally at 120°C with methacryl‐substituted polysilsesquioxane (ME‐PSQ) prepared from 3‐(trimethoxysilyl)propyl methacrylate and tetramethylammonium hydroxide. The dynamic mechanical and thermal properties of the VER…
Porous silicon layers (PSL) were fabricated by electrochemical etching and investigated by spectroscopic ellipsometry (SE) in the energy range 0.6−5 eV. Within the effective medium approximation (EMA) and through an optical model consisting of a mixture of void and crystalline silicon (cSi), we were able to determine…
The synthesis and characterization of (Ba 0.5 Sr 0.5 ) 6 Mn 4 Cr 2 O 17 is reported.
