In this paper, we present an equivalent circuit (EC) based technique which combined with the numerical method to optimize the EBG structures with simple square-loop frequency selective surfaces (FSSs), they can take on in-phase reflection characteristic in some broad-band electromagnetic band gap (EBG) structures. By…
All mechanical rebar splices used in domestic nuclear power plant construction sites have been made by foreign manufacturers. Among them, ERICO’s Cadweld (sleeve with ferrous filler metal splices type) has been most commonly used in preceding nuclear power plants owing to the wide field application, but as it is forei…
Fibrous biomaterials can be utilized for different applications. Compression processing is a highly efficient way to reduce the transportation cost. Most biomaterials including agricultural fibrous materials exhibit viscoelastically when subjected to stress and strain. In this paper, the creep properties of timothy ba…
Primary pipe rupture is an important design base accident in the high temperature gas cooled reactor (HTGR). When a primary pipe of the HTGR ruptures, helium coolant gas in the reactor blows out into the reactor confinement structure and the reactor primary system depressurizes. After the pressures of the reactor and…
A doublet is revealed in the light extinction spectrum of a thin silver island film and the explanation of its nature is proposed. Based on the electron microscopy data, it is found that the doublet cannot be formed only by intrinsic resonances of individual islands. Because of interisland interactions, light can exci…
High dielectric polymer nanocomposites are promising candidates for energy storage applications. The main criteria of focus are high dielectric breakdown strength, high dielectric constant and low dielectric loss. In this study, we investigate the effect of the addition of TiO2 particles to PVDF matrix on the dielectr…
This study was aimed at the performance of micro methanol steam reformer for channel widths optimization by simplified conjugate gradient method (SCGM) with minimum objective function of velocity standard deviation. A three-dimensional numerical model and optimal algorithm named simplified conjugate gradient method (S…

Pressure vessels are common components of plant currently in operation within the nuclear industry and elsewhere. Their assessment and maintenance is of paramount importance to the integrity and safe working of the plant. Often these pressure vessels contain highly corrosive substances, which over time, cause deterior…
New lubricants are among the tools being deployed by the powder metallurgy industry to increase compressibility by, paradoxically, using less of them. Allied to cheaper alloying elements they could make an important contribution to the economic equation…
Nematic liquid crystals (NLCs) can be easily reoriented by the laser beam at the temperature closed to the nematic–isotropic phase transition (TNI). At the temperature closed to TNI, the propagating mode of laser beam and the optically induced phase transition were explored by using a microscopic conoscope technique.…
Electric conductive plastic composites have a wide potential for commercial applications, some examples are EMI shielding housings and components in automotive industry and in consumer electronics, equipments in health care sector and fuel cell components. A phenomenon in conductive composites, especially in composite…

High-precision three-dimensional woodpile photonic crystal and high-quality-factor nanocavities in various crystal orientations are fabricated with two types of directional etching methods in a simple two-patterning process.
En soudage, l’apport localisé et rapide de chaleur ainsi que son écoulement conduisent à des cycles thermiques qui peuvent modifier l’état mécanique et métallurgique des pièces à assembler. Ces modifications peuvent introduire, en fonction de la nature du matériau, des fissures préjudiciables pour la tenue en service…
We present experimental results on ultrafast electron diffraction from transiently aligned molecules in the absence of external (aligning) fields. The molecules are aligned selectively through a photodissociation reaction using a femtosecond laser pulse.
Particulate contaminated lubricants can be detrimental to any tribosystem. Debris can originate from the external environment, be unintentionally introduced during fabrication, or be generated internally during operation. These particles, if not carefully filtered out, can have serious implications on the integrity of…
In MEMS/NEMS applications, it is always desirable to have materials with good mechanical properties such as high strength and corrosion resistance. Metallic glass thin films are known to exhibit such properties. Here we report on properties of magnetic metallic glass (Fe0.72B0.24Nb0.04)(100-x)Ndx(4≤x≤8) thin films for…
In this work, we present a novel approach for the size fractionation of gold nanoparticles (Au-nps), which combines the nucleotide-mediated stabilization mechanism for Au-nps to the size-dependent colloidal stability of nanoparticles. Under nucleotide-coating, Au-nps undergo reversible salt-induced aggregation in aque…
Polypropylene (PP)/magnesium hydroxide (MDH) composite was melt-mixed using a twin-screw extruder. Two types of MDH were used, one with the modification of silane and another without. The rheological behavior was measured by capillary and dynamical rheometer. Microstructure of these composites was observed by SEM. The…
