A tunable infrared plasmonic polarization filter is proposed and investigated in this paper. The filter is based on the sandwich absorption structure which consists of three layers. The top layer is an array of asymmetrical cross resonator. The middle and bottom layers are dielectric spacer and metal film respectively…
Automotive and aerospace manufacturers are looking for ways to reduce the gross weight of vehicles to economize on fuel consumption as well as improve performance. Magnesium alloys, being the lightest among the metals, are highly attractive as potential structural materials. However, their use is quite limited, especi…
Radioactive waste drums filled with compacted metallic residues (spent fuel hulls and nozzles) produced at AREVA La Hague reprocessing plant are measured by neutron interrogation with the Differential Die-away measurement Technique (DDT). The purpose is to assay fissile material quantities present in radioactive waste…
A solid-state thermoelectric refrigerator with a cylindrical InP/InAs/InP double-barrier heterostructure is proposed. Based on the ballistic electron transport and the asymmetrical transmission, we derive the expressions of the performance parameters of this refrigerator. The cooling rate rather than the coefficient o…
The microstructures and magnetic properties of nanoparticles, each composed of an antiferromagnetic (AFM) manganese-oxide shell and a ferromagnetic-like core of manganese—gallium (MnGa) compounds, are studied. The core-shell structure is confirmed by transmission electron microscope (TEM). The ferromagnetic-like core…
Abstract In an aqueous dispersion of a novel polymerizable amphiphile containing hydrolyzable linkages, spherical or tubular giant vesicles were formed after the polymerization reaction, even though the hydrolysis of the amphiphile also occurred. This is probably due to the stabilization of the membrane structure comp…
Salicin (salicyl alcohol glucoside) is a substance well known for its bitter taste. A photoreactive diazirinyl derivative of salicin will be utilized for the functional analysis of interactions between the bitter taste receptor and salicin.
A novel nanocomposite composed of copper nanoparticles encapsulated in a hollow carbon shell was prepared. The thin, porous carbon shell ensured efficient mass and electron transport and provided a confined environment for electrochemical reactions. The Cu@C nanocomposite exhibited favorable electrocatalytic activity…
A pilot study was conducted to study the phytochemical and anti-inflammatory activities of methanol extract of leaves of Basella rubra. Phytochemical studies were carried out to determine the bio active constituents present in the methanol extract of B. rubra . Oxazolone induced inflammation model was used to evaluate…
The diffusion mechanism of a model anti-cancer drug in cross-linked poly(N-isopropylacrylamide/acrylic acid) (P(NIPAAm/AA) copolymeric hydrogels was studied. The crosslinking ratiowas constant but acrylic acid ratio ranged from 10:1 to 10:3. P(NIPAAm/AA) copolymeric hydrogels were synthesized by redox-initiated free r…
Given the dominance of surface energy, small crystallites are disfavoured relative to larger crystallites, and nucleation has to overcome an energy barrier before the volume energy starts to drive crystal growth. Small particles are formed under conditions of high oversaturation because this triggers instant formation…
The nonlinear dynamic characteristics and optimal control of a giant magnetostrictive film (GMF)-shaped memory alloy (SMA) composite plate subjected to in-plane stochastic excitation are studied. GMF is prepared based on an SMA plate, and combined into a GMF—SMA composite plate. The Van der Pol item is improved to exp…
Abstract In nuclear industry, the purity of hafnium control rod is usually significant, and the process parameters will affect the impurity contents. In this study, the four key factors (filament temperature, retort materials, feeds, and iodide reaction time) were investigated. It is found that the impurity contents o…
We analyze the combined effect of three ingredients of an aggregation model--surface tension, particle flow and particle source--representing typical characteristics of many aggregation growth processes in nature. Through extensive numerical experiments and for different underlying lattice structures we demonstrate th…
We present a variational density-functional perturbation theory (DFPT) to investigate the lattice dynamics and vibrational properties of single crystal bismuth telluride material. The phonon dispersion curves and phonon density of states (DOS) of the material were obtained. The phonon dispersions are divided into two…
The indolo[2,3-a]carbazole scaffold is a fused polyheteroaromatic system bearing two NH groups which suitably converge as hydrogen bond donor sites for the recognition of anions. A simple derivatisation of the indolocarbazole system at positions 1 and 10 with different functional groups, namely alcohols and amides, ha…
In this study, a modification procedure for ramie fabrics was developed using modified cellulases. Cellulase was modified by covalent coupling to Eudragit S-100, which resulted in a larger molecule, to trigger its activity toward the cellulosic fiber surface. The modified fabrics were characterized by using atomic for…
Three-dimensional video imaging has emerged as an indispensable tool for real-time monitoring of dynamic acidic organelles. However, the limitation of video imaging is the absence of a specific stain for acidic organelle trackers. The aim of this work was to investigate the applicability of a potential acidic organell…
Bottom-gate single-walled carbon nanotube (SWCNT) network thin-film transistors (TFTs) are fabricated and their low-frequency noise characteristics evaluated. Clear 1/ f ( f : frequency) and ( I DS : drain current) dependences are observed in the drain current noise power densities. The A / R ( A : noise coefficient a…
We report a novel approach to obtaining a classical blue-green excitable CaS:Eu 2+ phosphor with desired red emission by microwave (MW) firing procedure in the absence of adding elemental sulphur. The disturbing effect of MW electromagnetic field on decomposition of CaSO4 into CaS activated by europium is distinctly o…
