The application of Sea sand concrete, to solve the problem of affecting the durability become focus. Chlorine salt is sea sand concrete part. Based on cement, fly ash, sand, the desalination sea sand as experimental material. In were magnified 100 times, 1000 times and 8000 times of HCA0 (blending 0.01% chlorine ion w…
In this paper, a compact dual-band antenna is successfully proposed and presented. This type of antenna consists of a coplanar waveguide (CPW) composite right/left-handed (CRLH) quarter-wave type resonator, and a CPW feed network. The characteristics that the CRLH resonator can resonate at the frequency where the elec…
Abstract The title compound is synthesized ba solid state reaction of an equimolar mixture of the elements (evacuated silica tube, 1273 K, 99 h) followed by treatment in a Sb2Se3 flux under the same conditions.
Glyoxylic acid (GA) has been reported to be a promising autocatalytic reducing agent in electroless copper for more than 26 years, which can eliminate the environmental hazards, health and safety concerns associated with formaldehyde. This paper will introduce a novel and environmental-friendly electroless copper proc…
The results of an investigation of the structure, composition, and topography of the surface of buffer layers of CeO 2 , LaNiO 3 , and CeO 2 + LaNiO 3 on nonmagnetic textured NiCr 9.2 W 2.4 substrates with a cube texture, which were prepared by pulsed laser deposition, are presented. The substrates with a buffer layer…
Fungus corrodes silk and makes their products quickly corrosion and crisp. This article disclosed that the silk fabrics treated with finishing resins containing isothiazolone to form the closing film. On the one hand, the film can prevent fungus penetrating into silk fiber matrix. On the other hand, it can make use of…
A novel photochromic diarylethene 1-(2-methylbenzothiophene-3-yl)-2- [2-methy-5-(4-methoxyl-3-formyl) phenyl-3-thieny perfluorocyclopentene (1a) has been synthesized. Its properties, including photochromic behavior and fluorescent features, have been investigated in detail. This diarylethene showed good photochromism…
Chitosan is a partially deacetylated polymer of acetyl glucosamine obtained byalkaline deacetylation of chitin. It displays interesting properties such as biocompatibility, biodegradability as its degradation products are non-toxic, non-immunogenic, and non-carcinogenic. It can be modified chemically for the presence…
The cover picture shows the unit cell of a layered dysprosium hydroxide material, Dy8(OH)20Cl4·6H8O, viewed along the b axis (left) and the c axis (right). The SEM image indicates the high crystallinity of the particles. The temperature dependence of the imaginary component of the AC susceptibility (χ″) under zero DC…
Abstract The new title compound is synthesized by solid state reaction from mixtures of KP, Si, and P in the molar ratio of 1:2:2 (750 °C, 4 d).
For almost all materials the hypervelocity regime has been reached when the impact speed above 2 km/s. A double-barreled two-stage light gas gun (TSLGG) system used for the hypervelocity impact tests is described. The proposed TSLGG can accelerate 50 g projectile masses up to velocities of 2.2 km/s. The craters produc…
Ferromagnetic glass-ceramics for hyperthermia application were obtained by melting of the co-precipitation-derived precursor from the nominal compositions SiO2-B2O3-Fe2O3-SrO-Na2O. The influence of boron content on magnetic performance of these glasses was investigated. Glass-ceramics were characterized by x-ray diffr…
This paper continues the study in the field of microheaters on flexible substrates. The idea of using flexible substrates comes together with the need for low manufacturing costs, having in mind the applications of sensors for home usage and other possible applications as monitors for buildings or basements where poss…
The purpose of this paper is to analyze distribution of surface charge density on DC-carrying conductor. A new numerical analysis method, based on finite element method, is proposed in this paper. Basically the method consists of two steps: first is to calculate inside field of conductor and second is to calculate out…
Electroluminescence generated during the short circuit of the polarized Linear low density polyethylene (LLDPE) sample is investigated. By measuring the electroluminescence and damped oscillation discharge current, the relations between the electroluminescence and discharge current was discussed. Results show that the…
In this paper we present mimicking of the electromagnetically induced transparency (EIT) effect, obtained in metamaterial transmission line loaded with two cross coupled SRRs placed at the opposite sides of the line. The increased group delay between 2ns and 3ns is observed in the EIT-like transmission band. We demons…
Energy absorbing characteristics of the non-stiffened and stiffened single hat sections subjected to quasi-static axial crushing were experimentally investigated. First non-stiffened hat sections were axially crushed, then structures with different stiffened methods (stiffened in hat and stiffened in the plate) were t…
Near stoichiometric and stoichiometric CuIn (1− x ) Al ( x ) Se 2 (CIAS) thin films have been prepared by chemical bath deposition (CBD) technique. X-ray diffraction (XRD) and energy dispersive x-ray analysis (EDAX) spectra have been employed to confirm the structure and composition of the prepared films. SEM analysis…
Pit and hillock textures enhance the light-coupling efficiency of silicon solar cells. In a bioinspired pit/hillock texturing scheme, inspired by the compound eye of the common housefly, the surface of the silicon solar cell is textured as an array of parallel and equally spaced grooves/prisms whose cross-section is a…
The main focus of this paper is concerned with the production and properties of refuse derived fuel 5 (RDF-5) for use in energy from waste technologies. The analysis was performed using feedstocks made up of residues from a range of mechanical biological treatment (MBT) plants and crude oil sludge. The RDF-5 was compo…
