Diesel oil used as fuel in motor engines has been used as a precursor for the production of carbon nanomaterial without a catalyst precursor. Nanomaterials formed in the process were analysed by High resolution transmission electron microscope, (HR-TEM), Raman spectroscopy, scanning electron microscope (SEM), energy d…
We have used small angle X-ray scattering (SAXS) to quantitatively characterize the morphology of vertically aligned (VA) multiwall carbon nanotube (MWCNT) arrays. We examined the extent of alignment of MWCNTs in terms of order parameter by analyzing SAXS intensity as a function of azimuthal angle. The SAXS measuremen…
This paper reports experimental investigations on pressboard surface treeing processes and the accompanying creepage discharge patterns. With the help of fast digital video recorder, wideband discharge current sampling resistor and commercial PD detector, it is found that the liquid impregnated pressboard as composite…
This paper describes the modelling of capacitor voltage transformer and simulation of its behaviour during transients using PSCAD/EMTDC. To damp out ferroresonance in CVT few ferroresonance methods have been proposed and used. In this paper, some of the suppressing circuits, series resonance type, parallel resonance t…
Sclareolide (1) was incubated with eight different species of filamentous fungi conventionally used for bio-oxidations. Compound 1 was metabolized with Aspergillus niger in medium A to yield 3-ketosclareolide (2) and 3β-hydroxysclareolide (4), while in medium B (containing major number of nutrients with respect to med…
This paper reports a qualitative comparison between the optical properties of a set of silver core, gold shell nanoparticles with varying composition and structure to those calculated using the Mie solution. To achieve this, silver nanoparticles were synthesized in aqueous phase from a silver hydroxide precursor with…
The structure and mechanical properties of nanostructured titanium VT1-0 derived using an ingenious method which combines helical and longitudinal rolling are studied in comparison with the properties of commercial titanium alloys VT6 and VT16, as well as VT1-0 in a coarse-grained state. The mechanical properties of t…
Polyamides containing main-chain cyanine chromophores are synthesized, and their molecular, nonlinear optical, and mechanical properties are studied. It is shown that the Kerr electro-optical effect in polymer solutions is determined by the rigidity of polymer chains and that the nonlinear optical properties are depen…
Depletion-mode CNTFETs have been fabricated on 4" wafers with a photostepper-based process. The transistors show significant current and power gain with peak (fT, fmax) values of (9, 10) GHz. Compact model results are compared to experimental characteristics over bias and frequency. First RF amplifier circuit results…
Lead-free K0.5Na0.5NbO3 (KNN) nanotube arrays were synthesized by a sol-gel method with anodic aluminum oxide templates. The obtained KNN nanotubes exhibited a polycrystalline and monoclinic perovskite structure with diameters of ∼200 nm and wall thickness of ∼30–40 nm, respectively. The polarization-electric loop cur…
The evolution of the defect substructure in V-4Ti-4Cr alloy under its severe plastic deformation by torsion in Bridgman anvils is studied by transmission electron microscopy. Nanoband structural states with a dipole or multipole character of misorientations and a crystallite (or nanoband) size varying from several to…
This paper is dedicated to the design of efficient antimicrobial pharmaceuticals based on chitosan. Chitosan with a deacetylation degree of 0.98 preliminarily treated with supercritical carbon dioxide (scCO 2 ) was impregnated with organometallic complexes (silver cyclooctadiene(hexafluoroacetylacetonate) and copper h…
This paper presents a novel method to improve simulation of the road salt deposit process on energized high voltage insulators under winter conditions. A pollution generator system prototype was especially designed to produce an external mixing of dry solid contaminants (kaolin powder) with supercooled atomized brine…
The complex of terbium(III) with dipivaloylmethane (2,2,6,6-tetramethylheptane-3,5-dione = Htmhd) [Tb(tmhd)3]2 (1) and two its adducts with bipyridyl (Bipy) and phenanthroline (Tb(tmhd)3·Bipy (2) and Tb(tmhd)3·Phen (3)) are synthesized and analyzed by single crystal X-ray diffraction. The crystals of [Tb(tmhd)3]2 (1)…
Magnetic resonance imaging (MRI) offers the ability to visualize a number of biological processes at the molecular and cellular level. The quest for MRI methods that enable the monitoring of these processes with improved specificity and spatiotemporal resolution has induced a considerable amount of research into the c…
CeO2-based solid solutions with a fluorite structure are promising materials as electrolytes of medium-temperature electrochemical devices: electrolytic cells, oxygen sensors, and solid oxide fuel cells. In this work, studies are presented of the effect of the dopant cation radius and its concentration on the physico-…
In order to reveal the nature of the formation of a broadband reflection property for polymer stabilised cholesteric liquid crystal, the spatially periodic helix structure of epoxy cholesteric liquid crystal is ‘frozen’ by cationic polymerisation following the formation of a polymer network induced by ultraviolet radi…
Abstract This letter focuses on the synthesis of multi-walled carbon nanotubes (MWNTs) and MWNTs/ZnO nanocomposites using absorbent cotton. The MWNTs have been synthesized by a rapid heating of absorbent cotton at different temperature (400°C, 550°C, 600°C). The MWNTs/ZnO nanocomposites have been synthesized by heatin…
Durable non-fluorine hydrophobic cotton surfaces were obtained by treating woven cotton fabrics using combinations of silica nanoparticles and multifunctional silanes. Both the hydrophobicity and durability of treated cotton surfaces were controlled by selectively adjusting the alkyl chain length of silane hydrophobes…
Competitive adsorption of two-component solutions containing fibronectin (Fn) and albumin (Ab) on hydroxyapatite (HAp) nanocrystals was analyzed in situ using the quartz crystal microbalance with dissipation (QCM-D) technique. Adsorption of the one-component protein (Fn or Ab) and the two-component proteins adjusted t…
