Surface modification of polyester fabrics was studied aiming at improving the water repellency property. Vinyltriethoxysilane (VTES) was employed as surface modifying agent. Prior to application, VTES was prepared in aqueous emulsion using cetyltrimethylammoniun bromide (CTAB) as an emulsifying agent. The application…
Wood pulp fibres have mulitscale characteristics. Roughly, the length and width of fibres vary from 1-3 mm and 10-50 m, respectively. The fibre wall structure is mainly composed of well-organized fibrils with diameters in the nano-scale. The multi-scale structures of cellulose fibres require dedicated microscopy tech…
The paper presents an investigation of the liquid retention capacity of terry fabrics with respect to pile height and impacts/finishing. The terry fabrics used in the experimental work were made from linen or linen/cotton yarns. The pile height of the samples was 6, 9 and 12 mm. The fabrics were effected by various im…
having comparatively high area density which varied in the range of 211 g/m 2 – 398 g/m 2 . In parallel comparative analysis of BKESF and BFAST bending rigidity parameters provided in literature references was performed. Data of 80 different fabrics was analysed. The results of the investigation present the dependenci…
We propose a planar focusing antenna design, which has the same performance as its parabolic counterparts and can be realized using PEC-backed gradient index dielectrics. In this design, quasi-conformal transformation optics is first utilized to transform a parabolic surface into a planar one, then the anisotropy fact…
We calculate theoretically the dispersion curves and surface plasmon (SP) density of states (DOS) at the interface between gold and silver nanostructures and a dielectric medium. The SP DOS for the gold nanostructure has two maxima, one at the SP absorption wavelength, and another at a redshifted wavelength from the S…
Three new cluster compounds were synthesized from Hg(EPh)2 (E = Se, Te; Ph = phenyl) in organic solvents. Two of these compounds, [Hg2Cl2(SePh)2(PCy3)2], (1), and [Hg2Br2(SePh)2(PCy3)2], (2), were prepared by reaction of Hg(SePh)2, HgX2 (X = Cl, Br) and tricyclohexylphosphine, PCy3, in dimethylformamide. The reaction…
The development of low temperature, thin film transistor processes that has enabled flexible displays also presents opportunities for flexible electronics. A variety of flexible digital and analog electronics have been demonstrated, although typically of modest performance. We review the state-of-the-art in flexible e…
Rare earth copper sulfides, LnCuS 2 (Ln ¼ Ce, Pr, Nd, Sm, Gd and Tb), powders were synthesized by the following procedure: (1) Ln-Cu complex oxide was synthesized using the polymerized complex method, and (2) LnCuO 2 was sulfurized by the CS 2 gas.CS 2 gas sulfurization combined with a polymerized complex method can r…
BACKGROUND: The use of Di-2-ethylhexyl phthalate (DEHP) plasticised polyvinyl chloride (DEHPPPVC) in medical devices persists despite evidence suggesting that DEHP migration can be harmful. Researchers have shown that a simple surface sulfonation process can retard the migration of DEHP, which may reduce the associate…
Abstract A system's van der Waals–London dispersion interactions are often ignored, poorly understood, or crudely approximated, despite their importance in determining the intrinsic properties and intermolecular forces present in a given system. There are several key barriers that contribute to this issue: 1) lack of…
We synthesized lamellar solids by co-condensation of 3-(2-aminoethylamino)propyltriethoxysilane (AeAPTES) and tetraethyl orthosilicate (TEOS) in the presence of hexadecylsuccinic acid (C16SA) and hexadecanol (C16OH) producing a composition in the gel such that AeAPTES : C16SA was kept constant at 1 : 1, as is the rati…
Refluxing toluene solutions of [Mo(η(3)-allyl)(O(2)CMe)(CO)(2)(pz*H)(2)] (pz*H = pzH, pyrazole, or dmpzH, 3,5-dimethylpyrazole) without exclusion of air, give the tetranuclear complexes [Mo(2)O(2)(O(2)CCH(3))(2){(μ(3)-O)(μ-pz*)Mo(η(3)-allyl)(CO)(2)(pz*H)}(2)], where two chelating acetato ligands and two "Mo(η(3)-allyl…
Shape memory alloys (SMAs) are active metallic ``smart'' materials used as actuators and sensors in high technology smart systems [1]. The term shape memory refers to ability of certain materials to ``remember'' a shape, even after rather severe deformations: once deformed at low temperatures, these materials will sta…
Primary windings of transformers are fed with alternating sinusoidal voltage, but often this voltage contains small DC offset due to unsymmetrical voltage levels. To emulate such working conditions in a controlled environment (Epstein frame) the excitation waveforms were emulated as a DC voltage superimposed on an AC…
The water samples collected from two non water-flooded oil fields contained a variety of organic acids, sulfate-reducing bacteria (SRB) and little sulfate. Acetate and propionate were the major components of organic acids. Over 6 weeks of artificial souring experiment, a maximum of 3 mM of sulfide was produced when oi…
Abstract Thionine molecules have been electropolymerized onto different types of carbon nanotubes (CNT) using a cyclic voltammetry scanning technology, including multi‐walled carbon nanotubes, single‐walled carbon nanotubes and aligned carbon nanotubes. Results indicate that such prepared nanocomposites have combined…
Novel compounds endowed with a high two-photon absorption (TPA) cross-section and a high singlet oxygen quantum yield, are sought after for their possible application in anti-cancer therapies. In this paper we present a prototype macromolecule bearing a distyrylbenzene dimer as TPA unit and a [60]fullerene moiety for…
Spark-plasma sintering method was used to prepare dense proton conducting perovskite oxide . Analysis of X-ray powder diffraction data showed that the sample adopt the cubic crystal structure having the space group . Thermogravimetric analysis of prehydrated samples showed significant mass losses beyond due to loss of…
The development of low-cost carbon nanotubes is presented in this work. In the present work, various types of carbon nanotubes are synthesised in hot-wall chemical vapour deposition (CVD) reactors using different temperatures and carbon sources (hydrocarbons). Growth rates were continuously monitored using an electron…
