The synthesis of a conformal poly(3,4-ethylenedioxythiophene) (PEDOT) layer on Si nanowires was demonstrated using a pulsed electrodeposition technique. N-type Si nanowire (SiNWs) arrays were synthesized using an electroless metal-assisted chemical etching technique. The dependence of the SiNW reflection on the concentration of the AgNO3 solution was identified. A reflection of less than 2% ove...
Deterioration of reinforced concrete members and their repair methods have been reported in various concrete published reports. Electrodeposition method is one of these repair methods for repairing deteriorated concrete members using an electrochemical mechanism. The purposes of the electrodeposition method are to fill cracks in concrete and to coat the concrete surface by electrodeposits of ch...
The superconducting properties of hierarchical nanostructured samples Pb–In alloys have been studied by the measurement dynamic susceptibility χ(T) temperature dependence. Symmetric with different shapes and sizes were formed on a brass metallic net cathode-metal electrodeposition programmed pulsing current. Two kinds dependence observed in synthesized structures. first kind was broad supercond...
High-quality performance of catalysts is increasingly required to meet industry exigencies. However, chemical synthesis often insufficient maximize the potential properties catalysts. On other hand, electrochemical has arisen as a promising alternative overcome these limitations and provide precise control in preparation In this sense, work involved well-controlled catalyst based on platinum na...
The objective of this work is to study the effect of two key factors external magnetic field and applied current density during template-based electrodeposition of nickel nanowires using an electrode distance of 20 mm. Morphology, length, crystallite size and crystallographic characterization of the grown nickel nanowires at an electrode distance of 20mm are presented. For this electrode distan...
Nanoscale particles offer a variety of interesting properties, and there is growing interest in their assembly into higher ordered structures. We report that the pH-responsive aminopolysaccharide chitosan can mediate the electrodeposition of model nanoparticles. Chitosan is known to electrodeposit at the cathode surface in response to a high localized pH. To demonstrate that chitosan can mediat...
Electrodeposition is a widely used materials-deposition technology with a number of unique features, in particular, the efficient use of starting materials, conformal, and directed coating. The properties of the solvent medium for electrodeposition are critical to the technique's applicability. Supercritical fluids are unique solvents which give a wide range of advantages for chemistry in gener...
