We report on the method of enhancement of the electrical conductivity of poly(3,4-ethylene dioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) films through a treatment with newly found organic additives, such as ethylene carbonate (EC) and ethylene sulfite (ES). Addition of these secondary dopants to PEDOT:PSS aqueo…
Development and testing of a novel armor system that defeats high-velocity projectiles and penetrators is described, from a phenomenological perspective. The process is covered where fundamental principles of shock mechanics and high fidelity computational physics (HFCP) simulations are used to create the armor system…
Gold nanocomposite of Polyaniline was prepared by chemical synthesis method and its thin film was made by drop casting. The Schottky junction of thin film was fabricated with aluminium metal. TGA analysis of the sample showed good stability. Current density-voltage characteristics of the junction showed good rectifyin…
One group of polymers that may help relieve the dependence on crude oil is based on itaconic acid, the biotechnological production of which has become feasible. Itaconic acid and its derivatives can easily be incorporated into polymers and may serve as a substitute for petrochemically derived acrylate or methacrylate…
In this work, a controllable hydrothermal synthesis of two-dimensional (2D) and three-dimensional (3D) dendritic aluminum phosphate crystals was implemented from a recipe containing alumina, phosphate, nitric acid and triethylamine (TEA) with or without the addition of cetyltrimethylammonium bromide (CTAB). The 2D den…
This paper briefly introduces the water transfer printing craft's basic concepts and characteristics, water transfer printing technology classification, material that water transfer printing technology uses , water transfer printing process of applications and the analysis of water transfer printing technology applica…
Hardfacing weld techniques apply mainly to improve the service life of engineering components either by rebuilding or fabricating a composite layer, which will protect the components from wear, erosion, and corrosion. However, hardfaced deposits are susceptible to cracks compared to the base metal due to thermal cycle…
Using first-principles electronic structure method, we have shown that at experimental lattice constant disordered phases of Mn2NiSn are favorable than the ordered structure. Total moments of the disordered phases are comparable to the experimental value. The large variation of moments at one of the Mn atoms stabilizi…

Grain growth, the most fundamental mechanism forming the internal structure in metallic materials, is affected by not only grain boundary (GB) energy but also other driving forces such as internal stress fields of defects. In order to determine the explicit distinctions between the simulated evolutions and the real me…
Potassium Dihydrogen Phosphate crystals are one of the most popular crystals used for Non-linear Optical applications. Most of the amino acids also exhibit NLO properties. The effect of doping of one of the amino acids, L-tryptophan in KDP crystals has been investigated. Pure and L-tryptophan doped KDP crystals were g…
Potassium sodium niobate (K1/2Na1/2NbO3) powder was synthesized successfully by the combustion synthesis. The raw materials of KNO3, NaNO3 and Nb2O5 were used with glycine as fuel. The thermal behaviour of the precursor was determined using thermo gravimetric analysis (TGA) and derivative thermo gravimetric (DTG) anal…
We consider the problem of distributing the stress-strain state (SSS) characteristics in the body arbitrarily loaded on the outer surface and weakened by a physical cut with a thickness of δ0. It is assumed that δ0 parameter is the smallest possible size permitting the use of the hypothesis of continuity. The continua…
A twin-screw extruder was used to carry out the ring opening graft polymerization of L-lactide onto cellulose through reactive extrusion process. Ionic liquid (1-butyl-3-methylimidazolium chloride) [Bmim]Cl and Sn(oct)2 were used as solvent and catalyst, respectively. FTIR, TGA and XRD were used to investigate the str…
Positive ion electrospray ionization mass spectrometry (ESI-MS) was used to characterize complexes formed in aqueous solution between Fe(III), Ga(III), In(III), Ce(III), Eu(III) or Yb(III), and the linear dihydroxamic acid suberodihydroxamic acid (HONHC(O)(CH2)nC(O)NHOH), n = 6; L6H4) at pH 2.5, and at metal (M) to li…
Nanofibers of an acrylonitrile copolymer (acrylonitrile-methacrylate-itaconic acid) are obtained by the electrospinning method from 51.5% NaSCN aqueous solutions at a voltage of 15 kV. The structural characteristics of these nanofibers are investigated. It is shown that, during electrospinning, the interplanar distanc…
A slanted columnar TiO2 sculptured anisotropic thin film is prepared using the glancing angle deposition (GLAD) technique. We extend the inference regarding the optical properties of a uniaxial birefringent film based on theoretical analysis to include the more general case of a multilayer biaxial birefringent thin fi…
Cohesive particles usually form very porous agglomerates. They support loads up to a consolidation pressure, which increases with decreasing particle size. Compaction of nano-powders can therefore be very costly and time consuming. If the particles are electrically conducting, which is the case e.g. for novel nano-str…
We report the transport, magnetic, and thermal properties of La0.7Ca0.24Sr0.06MnO3single crystal. It was prepared using floating zone technique used under oxygen pressure of 1 bar with a typical growth rate of 1 mm/hr. The resistivity data shows the metal to insulator transition (M-I) occuring at TMI=290 K along thec-…
In this study, chemical and structural properties of sea snail shell based bioceramic materials (i.e. hydroxyapatite, whitlockite and other phases) are produced by using mechano-chemical (ultrasonic) conversion method. For this purpose, differential thermal and gravimetric analysis (DTA/TG), X-ray diffraction, infra-r…
