3 mol.% Y2O3-ZrO2 (3Y-TZP) powder was prepared using the coprecipitation method. The effects of adding various amounts of aluminum oxide to the 3Y-TZP and the influence of sintering temperature were studied. The best microstructural and electrical properties from the viewpoint of application as solid electrolytes were…
In the last twenty years, the use of lignocellulosic fibers as filler to produce polymer composites has increased progressively. A lot of research work has been performed all over the world on the use of natural fibers as reinforcing material for the preparation of composites. The objective of the present work is to p…
Development of cell-instructive polymeric biomaterials is an area of intense research that has garnered widespread attention over the past decades and is critical to the clinical and commercial success in tissue engineering. Central to the reconstruction of complex tissues, it will require high levels of biochemical-b…
An integrated physical-chemical-mechanical approach was used to study the effect of adhesion on the mechanical strength of composites reinforced with bamboo and coir fibres, and three thermoplastic matrices (Polypropylene (PP), maleic anhydride grafted polypropylene (MAPP), and polyvinylidene fluoride (PVDF). Surface…
The surface plasmon resonance gas sensor is presented for refractive index detection using nano-cavity antenna array. The gas sensor monitors the changes of the refractive index by measuring the spectral shift of the resonance dip, for modulating the wavelength of incident light. It is demonstrated that minute changes…
This work explores the electronic states of CdTe semiconductor nanoparticles (NPs) that are immobilized on a polycrystalline Au film through an organic linker (dithiol). The HOMO and LUMO energies of the CdTe NPs were determined by using photoelectron spectroscopy and cyclic voltammetry. The results from these measure…
We show that the kinetic-theoretical self-diffusion coefficient of an atomic fluid plays the same role as the short-time self-diffusion coefficient DS in a colloidal liquid, in the sense that the dynamic properties of the former, at times much longer than the mean free time, and properly scaled with DS, will be indist…
Surface and internal charging of dielectric materials is a potential cause of surface discharges and satellite anomalies, due to the fluctuating irradiation levels induced by space environment. Understanding conduction mechanisms and reducing charging levels are therefore important industrial issues for satellite desi…
Paramagnetic lanthanide ions when bound to proteins offer great potential for structural investigations that utilize solution nuclear magnetic resonance spectroscopy, magnetic resonance imaging, or optical microscopy. However, many proteins do not have native metal ion binding sites and engineering a chimeric protein…
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…
