nanozinc oxide (n-ZnO) was synthesized by sol-gel method. The surface of n-ZnO was modified by a silane coupling agent. The modified n-ZnO was then used as rubber vulcanizing activator and nanofiller for BR/SBR blends. The size and morphology of n-ZnO were characterized by X-ray diffraction (XRD) and transmission elec…
Promise was shown for a method for producing complex oxide nanocomposites of europium, iron, and bismuth both as bulk powders, and as thin-film coatings on various supports by low-temperature pyrolysis of organic extracts based on extraction systems with various polyfunctional ligands. The magnetic properties of nanos…
When used as an implanted material, titanium (Ti) surface controls the subsequent biological reactions and leads to tissue integration. Cells interactions with the surface, through a protein layer that is being formed from the moment Ti surface comes in contact with blood and its components, and indeed this protein la…
The starting hesitation of a Switched Reluctance Motor (SRM) is an issue which must be considered in the early motor design. It is mostly handled as a control concern. The starting procedure of a SRM using a single Hall effect position sensor is analysed in this paper. This low cost position measurement solution requi…
The adsorption of flexible polyelectrolyte (PE) with the smeared charge distribution onto an oppositely charged sphere immersed in a PE solution is studied numerically with the continuum self-consistent field theory. The power law scaling relationships between the boundary layer thickness and the surface charge densit…
High-performance low-leakage-current AlGaN/GaN high electron mobility transistors (HEMTs) on silicon (111) substrates grown by metal organic chemical vapor deposition (MOCVD) with a novel partially Magnesium (Mg)-doped GaN buffer scheme have been fabricated successfully. The growth and DC results were compared between…
Influence of magnetic field annealing on room- and high-temperature magnetic properties of nanocrystalline (Fe0.5Co0.5)73.5Cu1Mo3Si13.5B9alloy was investigated. The initial permeability (μi) of nonmagnetic annealed samples decreases with annealing temperature (Ta) increasing, while the μiof magnetic annealed samples i…
The broadband optical absorption properties of silicon nanowire films fabricated by electroless metal deposition technique followed by HF/Fe(NO 3 ) 3 solution-based chemical etching at room temperature on p-type silicon substrates have been measured and found absorption higher than that of the solid thin films of equi…
An evaluation of a series of commercial uncoated, semimatte, and glossy coated woodfree papers for the multicolor sheet-fed offset press is presented. This study is aimed at better understanding of mutual influences of surface free energy, paper surface roughness, and fountain solution on print mottling occurring in f…
Objective: To estimate the prevalence of Brachyspira hyodysenteriae (B hyo) in breeding animals, lactating sows, and their suckling offspring in swine dysentery- (SD-) positive herds. Materials and methods: Study 1: lactating sows and suckling piglets. Rectal swabs were collected eight times at 1- to 4-week intervals…
The structure of bimetallic platinum-ruthenium catalysts was studied by X-ray phase analysis and X-ray absorption spectroscopy. The effects of strong electronic interaction of Pt and Ru atoms in formation of the binary catalyst were revealed. The kinetics of catalytic reduction of U(VI) with hydrazine and formic acid…
Resumen en: Introduction: The challenge of restoring patient’s function that presented some loss of an organ or tissue encourages the Tissue Engineering and Biotechn...
This paper introduces a low-cost infrared absorbing structure for an uncooled infrared detector in a standard 0.5 μm CMOS technology and post-CMOS process. The infrared absorbing structure can be created by etching the surface sacrificial layer after the CMOS fabrication, without any additional lithography and deposit…
Over the last 50 years, the study of radiological contamination and decontamination has expanded significantly. This paper addresses the mechanisms of radiological contamination that have been reported and then discusses which methods have recently been used during performance testing of several different decontaminat…
Gold nanoparticles have been shown to have interdisciplinary applications in multiple fields. In literatures, several fabrication processes have been developed, but the improvement of the stability and dispersion of the synthesized particles is very important to increase their applicability. In this article, facile ap…
We propose a broadband reflective metamaterial polarization converter which is composed of arrays of split-ring resonators (SRRs), a dielectric layer and a continuous metallic layer. For the case of a loss-free dielectric layer, the average transformation rate is around 90% at frequencies from 6.68 to 10.91 GHz, and t…
The hydrothermal synthesis and optical properties of Nb 5+ -doped lithium metasilicate and lithium disilicate nanomaterials were investigated. The microstructures and morphologies of the synthesized Li 2−2 x Nb 2 x SiO 3 + δ and Li 2−2 x Nb 2 x Si 2 O 5 + δ nanomaterials were studied with powder X-ray diffraction and…
Results of investigation of selective hydrogenation of unsaturated carbon-carbon bonds with hydrazine hydrate or complex metal hydrides in the presence of metal nanoparticles are reported. Conditions of exhaustive and partial hydrogenation of some derivatives of norbornene, styrene, and unsaturated carboxylic acids ar…
Ce3+activated terbium aluminum garnet ((Tb1-xCex)3Al5O12, 0≤x≤0.05) phosphors have been converted from their precursors synthesized via co-precipitation from mixed solutions of aluminum and rare earth nitrates with ammonium hydrogen carbonate (AHC) as the precipitant. Detailed characterizations of the precursors and t…
This paper deals with the effect of the intrinsic material length-scale parameter on the stability and natural frequency of a rectangular micro-plate for two different cases; fully clamped and fully simply supported. A variational formulation based on Hamilton ’s principle and the modified couple stress theory is used…
