The paper reports on tests done on four commercial room temperature vulcanized (RTV) silicone rubber high voltage insulator coatings aimed at achieving information on the relative performance of the coatings with respect to aging. The initial characterization of the coatings includes the identification of the primary…
Well-crystalline ultrathin GaS nanobelts have been successfully synthesized on silicon substrates by a simple thermal evaporation process. The GaS nanobelts were examined by X-ray diffraction (XRD), scanning electron microscope (SEM), high-resolution transmission electron microscope (HRTEM), and energy dispersive X-ra…
The maximum coordination number of the central atom in planar molecules generated by now in mole-cular beams was 8. We made use of the chemical bond model developed for planar boron clusters to check the possibility of existence of planar molecules with the coordination numbers 9 and 10. The objects of or study were t…
This paper focuses on the numerical study of heat and moisture transfer in clothing assemblies, based on a multi-component and multiphase flow model which includes heat/moisture convection and conduction/diffusion as well as phase change. A splitting semi-implicit finite volume method is proposed for solving a set of…
We demonstrate a wideband circular polarization reflector fabricated as cascades of helical films with different pitch thickness by using glancing angle deposition (GLAD) technique. The full-width-at-half-maximum bandwidth of this reflector is measured from the reflectance spectra and is found about 200 nm indicating…
We are reporting gravimetric measurements of adsorption isotherms and kinetics of water vapor in single-walled carbon nanotubes (SWNTs). Adsorption was facilitated in an open configuration. Adsorption capacities of SWNTs were found to be approximately one-half of those of activated carbon and activated carbon fiber. T…
A method to control the half-power relative band- widths of split ring resonators (SRRs) coupled to a transmission-line system is presented. An equivalent circuit model is proposed to analyze the main factors that effect the relative band- widths of SRRs. Based on the analysis, we propose an efficient way to control t…
We report on the synthesis of large and densely tough dendrimer-like star-branched polystyrenes of generation 3, specially designed for their visualization by AFM imaging. For this purpose, an iterative methodology involving a sequential three stages synthetic approach has been adopted. The precisely designed G-3 poly…
The isothermal crystallization of poly(L‐lactide) (PLLA) under steady‐shear flow was investigated in situ using an optical polarizing microscope with a hot shear stage. The steady–shear‐induced crystalline morphology of PLLA, to a great degree, depends on the crystallization temperature. There is a critical temperatur…
Four kinds of novel zigzag boron-carbon nanotubes with quasi-planar tetracoordinate carbons (2m, 0, i) (m = 3-6; i = 1-4) have been constructed, and their structures, stabilities, and bonding properties have been investigated by B3LYP calculations. The results show that the novel nanotubes (m, 0, i) have the character…
Abstract The thermal expansion behavior of a cyanate ester matrix reinforced by fumed silica nanoparticles with average primary particle diameters of 12 and 40 nm was investigated with thermomechanical analysis. All nanocomposites showed decreased coefficients of thermal expansion (CTEs) in comparison with the neat bi…
Nanosized β-SiC powder was prepared by combustion synthesis on a large scale, which was carried out in a N 2 atmosphere with silicon powder and carbon black as the reactants. Mechanical activation played an important role in enhancing the reactivity of the reactants, and a higher ball/charge weight ratio and a prolong…
Plate‐like Na 0.5 Bi 0.5 TiO 3 (NBT) particles with perovskite structure were synthesized by topochemical microcrystal conversion from plate‐like particles of layer‐structured Na 0.5 Bi 4.5 Ti 4 O 15 (NBIT) at 950°C in NaCl molten salt. As the precursors of NBT, plate‐like NBIT particles were first synthesized by molt…
The light efficiency of most well‐known nematic liquid crystal (LC) modes, such as twisted nematic and in‐plane switching, depends only on the cell retardation value, irrespective of the cell gap and dielectric anisotropy of the LC. Interestingly, the light efficiency of a homogenously aligned nematic LC cell driven b…
Multiwalled carbon nanocoils (CNCs) have been synthesized by a method of thermal chemical vapor deposition (CVD) using a codeposited thin film consisting of Fe and Sn as catalysts. It has been found that the multiwalled CNCs are thinner and have a higher crystallinity than conventional CNCs. The catalyst particles are…
Abstract Caliche in various forms, namely powdery, nodule, tube, fracture-infill, laminar crust, hard laminated crust (hardpan), and pisolitic crust, is widespread in the Mersin area in southern Turkey. It generally occurs within and/or over the reddish-brown mudstone of the Kuzgun Formation (Tortonian, Miocene) and a…
This paper presents a quadtree partitioning fractal image compression (QPFIC) method used for the partial discharge (PD) image remote recognition system. Self-similarity in PD images is the premise of fractal image compression and is described for the typical PD images acquired from defect model experiments in laborat…
The study of low-k TDDB line space scaling is important for assuring robust reliability for new technologies. Although spacing effects due to line edge roughness (LER) on low-k TDDB lifetime were reported previously (Chen et al., 2007; Lloyd et al., 2007; Kim et al., 2007), there has been a lack of an analytical model…
X‐ray diffraction measurements were carried out on nine members of the isothiocyanatobiphenyl homologous series (nBT) in their smectic E (SmE) phase, with the aim of estimating the layer thickness and deriving orthorhombic unit cell parameters for the SmE phase. The data obtained are discussed in relation to molecular…
The knowledge of the defect and impurity generation rates, as well as the defect spatial distribution, is the corner stone for the understanding of the evolution of material properties under irradiation. This knowledge is also an essential element for comprehensive experimental simulations of the behavior of irradiate…
