Metallic molybdenum (Mo(o)) wires with diameters ranging from 15 nanometers to 1.0 micrometers and lengths of up to 500 micrometers (0.5 millimeters) were prepared in a two-step procedure. Molybdenum oxide wires were electrodeposited selectively at step edges and then reduced in hydrogen gas at 500 degrees C to yield Mo(o). The hemicylindrical wires prepared by this technique were self-uniform,...

Pulsed electrolysis of copper has been systematically investigated by electrodepositing copper from a copper sulfate bath. Pulse duty cycles of 5 to 80 percent, at frequencies from 10 to 100 Hz with current densities ranging from 2.5 to 7.5 A/dm2 were employed. The appearance of Hull Cell panels with both direct current and pulsed current was recorded. The influence of pulsed current on current...

the combination of graphene (gr) and nickel oxide nanoparticles (nio nps) yields nanostructured electrochemical sensor formed a novel kind of structurally uniform and electrocatalytic activity material. in cyclic voltammetry (cv) studies, in the presence of ep, nio/gr composite modified electrode shows a significantly higher current response for ep oxidation. based on differential pulse voltamm...

in this paper, the effect of magnetic field on the morphology, structure and magnetic properties of electrodeposited fecu/cu thin films was investigated. the films were deposited on au2pdag/glass substrates using electrodeposition technique in potentiostatic control. the magnetic fields of 5000 and 7000 oe were applied on deposition bath during deposition. two series of thin films were prepared...

A new CFRP-aluminum joining method has been developed by Cu electrodeposition. deposition was filled into the roughened CFRP surface and significant anchor effect attained method. As a result, A6061 Al alloy were successfully joined electrodeposition high strength of 67 MPa obtained.

From previous experiments, it was determined that nickel was able to coat boron fiber, however this was done unevenly, with cracks characterizing the coating. This was where it was hypothesized that the boron fiber crossed the interface of the nickel electrolyte solution during electrodeposition. This was different than the coating at the middle, which was all under the electrolyte solution, an...

gd2o3 nanoparticles were prepared by a two–step process; cathodic electrodeposition followed by heat-treatment method. first, gd(oh)3 nanoparticles was galvanostatically deposited from nitrate bath on the steel substrate by pulse current (pc) mode. the deposition experiments was conducted at a typical on-time and off-time (ton=1ms and toff=1ms) for 60 min. the electrodeposited precursor was the...

in this work a rapid and selective procedure for separation and preconcentration of lead(pb2+) before determination by electrothermal atomic absorption spectrometry (etaas) wasdeveloped. the procedure is based on the electrodeposition on a graphite probe modified withpalladium. the lead was deposited from acetate buffer solution at ph 5.5. various parameters,such as ph of solutions, deposition ...

Deep eutectic solvents (DESs) comprising choline chloride (ChCl) with either urea or ethylene glycol (EG) have been successfully used as powerful and potential electrolytes for extracting metals from their corresponding metal oxide precursors. In this work, for electrodeposition of Zn and Zn-Cu alloys, ChCl/urea-based DES was employed. Cyclic voltammetry study demonstrates that the reduction of...
