The storage density of PCM has been demonstrated to double through the employment of Multi-Level Cell (MLC) PCM arrays. However, this increase in capacity comes at the expense of increased latency (both read and write) and decreased long-term endurance, as compared to the more conventional Single-Level Cell (SLC) PCM.…
We report the synthesis of high‐quality graphene on Cu foils using hot‐filament chemical vapor deposition technique and demonstrate that by suitably varying the CH 4 and H 2 flow rates, one can also obtain hydrogenated graphene. Micro‐Raman spectroscopy studies confirm the growth of monolayer graphene as inferred from…
The ability to simply and economically produce carbon nanotubes (CNTs) with a defined chiral angle is crucial for the exploitation of nanotubes for their electrical properties. We investigate a diverse range of nitrogen sources for their ability to control CNT chiral angle via epitaxial growth from highly ordered cata…
The equal channel angular pressing (ECAP) process is a promising technique for imparting a large plastic deformation to materials without a resultant decrease in cross-sectional area. In the present study, the suitability of this technique for the processing of tubular specimens has been investigated. Commercially pur…
Abstract Novel ferromagnetic semiconducting polyaniline PANI/TiO 2 nanocomposites were synthesized by the oxidative polymerization of aniline with ammonium peroxydisulfate in an aqueous medium, in the presence of colloidal TiO 2 nanoparticles ( d ∼ 4.5 nm), without added acid. The morphological, magnetic, structural,…
Cartilage tissue engineering requires a porous biodegradable scaffold and nonimmunogenic cells with chondrogenic potential. In this study, the ability of the placenta-derived mesenchymal stem cells (PMSCs) to grow on silk fibroin (SF) biomaterial was determined, and the potential of a SF biomaterial serving as a deliv…
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…
