In this paper, poly(aniline/pyrrole) (PANPY) copolymer was prepared in a mixed acid solution by electrosynthesis method. The molar ratio between the aniline and pyrrole monomer was found to great influence on the electrochemical perfprmance of PANPY copolymer. When molar concentration ratio of aniline and pyrrole to b…
In recent years, a lot of researches have done by domestic and foreign scholars to enhance and improve the development of man-made board production that based on natural fiber and agricultural residues. Due to a worldwide shortage of forest resources which have been excessive cutting, man-made board production has bec…
Folding clothes is a current trend in robotics. Previously to folding clothes, they have to be unfolded. It is not realistic to perform model-based unfolding, as every garment has a different shape, size, color, texture, etc. In this paper we present a garment-agnostic algorithm to unfold clothes that works using 3D s…
Isolation and characterisation of four predominant endophytic bacteria namely, Pencillium sp., Alternaria sp., Aspergillus sp. and Cladosporium sp. from different parts of Calotropis procera plant has been conducted in summer season. Among four isolated fungi Alternaria sp. exhibited the highest (33.33%) colonisation…
The efforts are geared to the development and application of environmentally friendly and sustainable bio-reinforced composites for use in automotive, construction, packaging and medical fields. In the study of Green polymer nanocomposites we learned unique properties of combining the advantages of natural fillers and…
The current control transformer on the market still continues the manufacturing process of traditional power transformer, silicon steel sheet as the main magnetic material has disadvantages of low energy efficiency and their own large loss. This paper analyzes the amorphous alloy used to manufacturing performance and…
A novel negative-resistance composite right/left-handed (NR-CRLH) leaky-wave antenna (LWA) is presented. The conventional CRLH unit cell is made configurable by using the negative resistance (NR) circuit. An LWA constituted by the proposed unit cells allows manipulation of the current distributions over the radiating…
This paper deals with diagnostic of composite insulation material which are currently used in high voltage appliances e.g. in large rotating machines - turbo or hydro generators. This composite is consist of calcinated mica paper, polyethylene terephthalate (PET) foil and epoxy-novolac resin. The insulation composite…
The results of studying the structure and properties of composite ceramic coatings produced by microarc oxidation (MAO) on zirconium alloy E110 are presented. To form the coatings, a suspension electrolyte is used with the addition of aluminum-hydroxide nanopowder. It is shown that the addition of the nanopowder resul…
Multilayered composites made of molybdenum and copper combine a low coefficient of thermal expansion with a high thermal conductivity. By varying the layer structure, both properties can be tailored to the application requirements. Therefore, these composites are interesting candidates for the thermal management of el…
This paper deals with the effect of inorganic micro/nanofillers and nanofabric on electrical tree growth in high voltage insulation. Experiments were conducted at a constant AC voltage of 20 kHz, 50 Hz epoxy samples without any fillers as well as epoxy nanocomposites with hydrophobic nanosilica or hydrophilic microsil…
The problem of the formation of a microrelief on the surfaces of polymeric bodies has been considered. The basis for a mesokinetic model of the formation of macromolecules, their aggregates, and polymeric bodies in a device filled with a monomeric solution has been reported. An equation for changes in the function of…
In this article, a photoalignment layer, based on the azo dye and liquid crystal polymer (LCP) composite is proposed. The alignment layer offers easy processing and high photo and thermal stabilities. The high VHR (99.1%) and low RDC (30mV) have been achieved that is comparable with the conventional PI rubbing alignme…
Pd0-catalyzed amination of 3-bromobenzyl-substituted azacrown ethers with propane-1,3-diamine affords the 3-(3-aminopropyl)benzyl derivatives, whose reaction with meso-(bromophenyl)-substituted porphyrins leads to bis- and trismacrocyclic conjugates.
The effect of holes on the band formation and the serrated deformation in planar specimens of aluminum–magnesium alloys AlMg5 and AlMg6 is studied by high-speed video filming of moving deformation bands. It is found that the concentration of an elastic field near a hole causes early nucleation of macrolocalized deform…

The in-plane strain fields of single-vacancy silicene with different monovacancy (MV) concentrations, as well as the corresponding electronic band structures, are investigated by using the first-principle calculations. Firstly the self-healing MV is found to be the most stable ground structure in silicene, which is di…
Nanoparticles of Eu3+ doped YPO4 have been prepared by co-precipitation method. The structure, morphology, composition and photoluminescence were characterized by X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDS), IR Spectroscopy, and Scanning electron microscopy (SEM) and Photoluminescence spectrosc…
Marine biomass resources are abundant and have a variety of functional groups, whose development prospect should be considerable. Tunicate is a kind of sea animal who can produce cellulose that was mainly composed of nanofibers. This review briefly introduced the progress in the architecture of tunicate cellulose and…
Cyclic thermal analysis is used to study the effect of overheating of the eutectic Ga–8.5 mol % Sn melt on the presolidification supercooling. It is found that, when the liquid eutectic is overheated above the eutectic temperature (T e = 293.5 K) and is subsequently cooled, the dependence of the presolidification supe…
