The construction of anticorrosion coatings containing antifouling agents is an effective way to ensure the long-term durability marine steel infrastructures. In this work, innovative hybrid coating was prepared by introducing biocide CuO nanoparticles in ordinary zinc improve its protective ability for aggressive salt water environments. were embedded inside matrix chitosan/alginate complexes p...
This study investigated the degradation of organic pollutants using an advanced electrochemical oxidation technique in a batch reactor cell consisting graphite anode, modified by electrodeposition PbO2, and graphene-modified carbon fiber cathode. The experiment was designed Taguchi design approach with orthogonal array L18 to optimize Chemical Oxygen Demand (COD) electro-Fenton process. Four pr...
Arrays of thermoelectric bismuth telluride (Bi(2)Te(3)) nanowires were grown into porous anodic alumina (PAA) membranes prepared by a two-step anodization. Bi(2)Te(3) nanowire arrays were deposited by galvanostatic, potentiostatic and pulsed electrodeposition from aqueous solution at room temperature. Depending on the electrodeposition method and as a consequence of different growth mechanisms,...
Membrane filtration fouling has become a significant issue that restricts its wide application. The electrocoagulation (EC) technique combines variety of synergistic pollutant removal technologies (including flocculation, redox, and air flotation), which can be an ideal pretreatment process for membrane filtration. In this work, novel Cu2+-doped polypyrrole-coated stainless steel mesh (Cu/PPy–S...
Unlike the more established lithium-ion based energy storage chemistries, the complex intercalation chemistry of multivalent cations in a host lattice is not well understood, especially the relationship between the intercalating species solution chemistry and the prevalence and type of side reactions. Among multivalent metals, a promising model system can be based on nonaqueous Zn ion chemistry...
CoFeCu nanowires were deposited by pulsed electrodeposition technique into the porous alumina templates by a two-step mild anodization technique, using the single-bath method. The electrodeposition was performed in a constant electrolyte while Cu constant was controlled by electrodeposition current. The electrodeposition current was 3.5, 4.25, 5 and 6 mA. The effect of electrodeposition current...
We report that oxide composite electrodeposition can be used for the facile preparation of metal-doped BiVO4 photoelectrodes for photoelectrochemical water oxidation. The photoactivity of electrodeposition film was improved by the addition of a small amount of tungstic acid particles during the electrodeposition. These particles are incorporated in the deposit and finally generate tungstendoped...
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...
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...
