Mesoporous nano zirconian was prepared by the self-assembly route using hexadecyltrimethyl ammonium bromide (CTAB) surfactant and employed as support for Nickel catalysts for selective methanation of CO. The CO methanation catalytic performance of the synthesized mesoporous nano zirconia-supported Ni-based catalysts w…
Mullite nanocomposites powders have been successfully synthesized from high-aluminium coal fly ash via hydrothermal crystallization process. The mullite nanocomposites powders are investigated and charactered by laser particle size analysis, BET surface area analysis, X-ray diffraction (XRD) analysis, transmission ele…
Grain interior precipitation and related lamellar forming grain boundary reaction in an Ag–Pd–Cu–Au–Zn alloy were examined by characterising the hardening behaviour, phase transformations, changes in microstructure and changes in element distribution during aging. The solution treated specimen was composed of the Ag–A…
Abstract Crystal structures of low temperature phases III, IV and V of Rubidium Zinc Bromide have been determined by single crystal X-ray diffraction at 90 K, 85 K, and 30 K, respectively. The analysis of the structures in terms of symmetry-adapted modes of the high temperature prototype phase permits the identificati…
PP/Ground Rubber Tire (GRT) powder microcellular blend foams were prepared by supercritical carbon dioxide. The effects of blend composition like the content of GRT and maleic anhydride-grafted polypropylene (PP-g-MA) on crystallinity, solubility, diffusivity, morphology and mechanical properties of PP/GRT microcellul…
Bismuth telluride (Bi2Te3) and its alloys are the most commonly used materials for thermoelectric devices. In this research, Bi2Te3chips of 9 mm × 9 mm were coated with 100 nm titanium (Ti) and 100 nm gold (Au) as barrier layer and plated with 10 μm Ag layer. Alumina substrates with 40 nm TiW and 2.5 μm Au were plated…
ZnO materials with different morphologies (hexahedron, coneflowerlike, cauliflowerlike, and nanorods) have been synthesized via a bioinspired method, which is effective and facile for the controlled synthesis of ZnO. Zinc acetate and ammonia were used as growth precursors, and ampicillin was used as the morphology-dir…
50% Line Edge Roughness (LER) correlation has been observed after spacer formation in 20nm half pitch (HP) interconnects using Spacer- Defined Double Patterning (SDDP) approach. This correlation has a positive impact on Time-Dependent Dielectric Breakdown (TDDB) lifetime, which was also predicted by simulations. Compa…
We report on how to determine asymmetrical director distribution throughout a liquid crystal layer such as a bistable hybrid-twisted nematic (BHTN) liquid crystal device by means of renormalized transmission spectroscopic ellipsometry. The advantage of the plural oblique incidence spectroscopic ellipsometry (POISE) is…
Mechanochemical processing of the silicon nitride based powders by high energy milling in a planetary mill is reported. The particle size distribution, specific surface area and their morphology after milling were studied after a period of a short (30 min) or long (up to 360 min) grinding. It has been shown that mecha…
We propose the use of methylating chemicals to repair plasma-damaged sites in low-k films. Dimethyl carbonate (DMC) and dipivaloyl methane (DPM) were selected as the methylating chemicals to supply methyl (CH3) groups into the bulk of damaged porous SiOCH films. The absorption of water into the damaged films was fully…
Photoluminescence properties of barium thio- and selenogallates doped with Eu2+, Ce3+ and co-doped with Eu2+ and Ce3+ were studied in a temperature range of 10–300 K and an optical excitation intensity interval of 3×10-4–1.25×106 W/cm2. Barium thiogallates doped with europium and co-doped by both rare-earth elements s…
In order to improve water-resistant ability silk fibroin (SF) and SF/P(LLA-CL) blended nanofibrous scaffolds for tissue engineering applications, methanol vapor were used to treat electrospun nanofibers. SEM indicated SF and SF/ P(LLA-CL) scaffolds maintained nanofibrous structure after treated with methanol vapor and…
The aim of this article is to provide an overview on the effect of Co doping for Fe in Fe2P on the lattice parameters, magnetic transition point, saturation magnetic moment, paramagnetic Curie point and paramagnetic moment. Five alloys in the series (Fe1-xCox)2P (x= 0.03, 0.10, 0.30, 0.50, 0.70) were synthesized and i…
A quick and simple test method for measuring the B-H curve and power loss in generator stators, both as loose laminations and finished core packs, has been developed. This provides a greater level of understanding about the characteristics of stator cores at various stages of the manufacturing process in order to prev…
Activated carbons (ACs) were prepared from lignin as the char precursor by means of the KOH activation method. The influence of KOH char mass ratio (K/C) on the pore properties and morphology of ACs, which play an important role on the electrochemical behavior of AC electrodes, were investigated by scanning electron m…
Polyaniline(PANI)/Ag nanocomposites, synthesized by incorporation of separately prepared silver nanoparticles in 1-methyl-2-pyrrolidinone(NMP) solution of PANI, have been aged at the accelerated temperature of 120 °C to simulate a storage period of 2 years at 25 °C. The accelerated ageing of these materials is done by…
We have systematically synthesized a series of perovskite related layered structures, Strontium-Niobates expressed as Sr n Nb n O 3 n +2 ( n = 4 ~ 5) and focused on the thermoelectricity in n = 4 and 5 type materials here.

Paramagnetic and diamagnetic materials are now generally known as the 'Cinderella' materials of the magnetic world. However, susceptibility measurements made on these materials in the past have revealed many details about the molecular bonding and the atomic structure of the so-called 'transition' elements. Indeed, th…
