Stabilized and size-controlled gold nanoparticles were synthesized using molybdophosphoric acid (H3[PMo12O40], HPMo) and its vanadium-substituted mixed addenda (H3 + x [PMo12 − x V x O40], (x = 0–3); and HPMoVx) under UV irradiation by a simple green method. In the process, HPMo and HPMoV x play the role of photocatal…
Effects of interfaces and interphases in polydimethylsiloxane (PDMS) matrices with in situ synthesized titania (20 - 40 nm, in diameter) and silica nanoparticles (~5 nm), were studied employing dielectric and thermal techniques. The presence of the well dispersed inorganic particles and the hydrogen polymer - filler b…
It has been experimentally found that the surface roughness influences strongly the surface and bulk plasmon excitation by glancing-angle reflection electron energy loss spectroscopy (REELS). However, there is still little theoretical work dealing with the surface roughness effect in REELS. Such a work is required to…
We present here the structures and magnetism of two quasi-1D linear chain compounds of BiM(2)BP(2)O(10) (M = Co, Ni), which were synthesized by traditional solid-state reactions for the first time. Two title compounds crystallize in the monoclinic system with space group P2(1)/c and feature novel 3D structures with a…
In this article, we present a graphical Computer-Aided Design (CAD) environment for the design, analysis, and layout of Carbon NanoTube (CNT) Field-Effect Transistor (CNFET) circuits. This work is motivated by the fact that such a tool currently does not exist in the public domain for researchers. Our tool has been in…
We propose an approach that improves the measuring precision of lattice parameters in semiconductor alloys from high resolution transmission electron microscopy images on the unit cell scale. The method is based on the evaluation of a series of images taken under optimized imaging conditions in an aberration corrected…
Samarium doped lead-zinc-phosphate glasses having composition (60−x)P 2 O 5 -20PbO-20ZnO-xSm 2 O 3 where x=0, 0.5, 1.0, 3.0mol% were prepared by using the melt quenching technique. The Archimedes method was used to measure their densities, which are used to calculate the molar volumes. The values of densities lie in t…
Abstract Attempts at optical resolution and asymmetric syntheses using smectite clay minerals are described. Use of the method was prompted by the discovery that the saturated adsorption of a tris(chelated) metal complex, [Ru(1,10-phenanthroline) 3 ] 2+ , by Na-montmorillonite depended heavily on the stereochemical pr…
In this paper, we present double-layer radar absorbing structures composed of E-glass fabric/epoxy composite laminates that are optimally designed to have a broad bandwidth in the X-band. The first layer is a pure E-glass fabric/epoxy composite laminate and the second layer is a carbon nanocomposite laminate. Composit…
In this work, we have synthesized carbon nanotubes (CNT) using different bio-hydrocarbon precursors namely palm, olive, coconut, corn and sesame oils. Prior to the synthesis process, thermogravimetric analysis (TGA) characterization was performed on the carbon precursors to facilitate the optimization procedures of CN…
The magnetic properties of vacancies in 2D hexagonal structures—graphene and 2D-SiC and h-BN monolayers—have been studied. It has been found that a local magnetic moment exists in all listed systems in the presence of vacancies. However, in 2D hexagonal silicon carbide, the local magnetic moment appears only in the pr…
A project to realize, in several years, a W/Cu divertor on Experimental Advanced Superconducting Tokamak (EAST) with ITER-like plasma-facing component (PFC) configuration was launched at Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP) in 2010. The ITER-like configuration should withstand the rapid inc…
The recent advances in nanotechnology and its application in medicine have merged into a new concept called nanomedicine. Colloidal drug delivery systems and specifically polymeric nanoparticles are one of the most promising novel drug carriers due to their capacity for passive or active targeting for therapeutic and…
The chosen materials for plasma facing components for the deuterium/tritium phase of ITER are beryllium and tungsten. These materials have already been widely investigated in various devices like ion beam or electron beam tests. However, the operation of this material combination in a large tokamak including plasma wa…
A template-based lamination technique for the manufacture of ferroelectrets from uniform electret films was recently reported. In the present work, this technique is used to prepare similar ferroelectret structures from low-density polyethylene (LDPE) films and from fluoro-ethylene-propylene (FEP) copolymer films. A c…
The experimental results of a comprehensive investigation of the structure of detonation synthesis nanodiamonds by electron microscopy methods have been presented. The morphology of diamond nanoparticles has been investigated and the microdiffraction patterns have been analyzed. The method of characteristic fast elect…
Block copolymer micelles have shown great potential in drug delivery systems, not only for overcoming the drawbacks of small agents such as water insolubility and wide distribution in normal tissues, but also for avoiding traditional nanoparticle formulation shortcomings, including in vivo instability and fast clearan…
BACKGROUND AND METHODS: Paclitaxel, a widely used antitumor agent, has limited clinical application due to its hydrophobicity and systemic toxicity. To achieve sustained and targeted delivery of paclitaxel to tumor sites, liposomes composed of egg phosphatidylcholine, cholesterol, and distearolyphosphatidyl ethanolami…
In this paper, the effect of the applied field frequency on the breakdown performances of cross-linked polyethylene (XLPE) insulation was investigated. Three kinds of artificial defects, namely an inserted needle, a needle void and a knife void, were introduced into a 10 kV commercial XLPE cable, to simulate real defe…
β-Ga2O3 nanostructures (nanowires, nanoribbons, and nanosheets) were synthesized via vapor transport method on gold coated silicon substrate in N2 ambient and these β-Ga2O3 nanostructures grown on silicon substrates were taken as the starting material to study the effect of annealing in the different environments (oxy…
