A common production method for nanowires is based on electrodeposition into cylindrical channels of a nanoporous template. Since the nanostructures adopt the morphology given by the host material as they are created by reduction from an electrolyte solution, the deposition step can be considered as the most important factor that determines the structure. Pt nanostructures are of particular inte...

Hydrogen evolution assisted electrodeposition is a new bottom-up technique allowing the fast and simple synthesis of nanometals. Electrochemical dealloying is a top-down approach with the same purpose. In this work, we show that a combination of these two methods in sequence by pulse-reverse electrodeposition can be used to prepare high-surface-area nanostructured metals. Highly porous adherent...

The effect of two leveling additives, thiourea (TU) and coumarin (CM), on cobalt electrodeposition process in an ionic liquid (IL), 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide (C4mimTFSA), at the gold surface has been analyzed situ using electrochemical plasmon resonance (ESPR), which SPR angle (??) recorded simultaneously with cyclic voltammograms. additives show ?? behavior...

A nickel-nanodiamond composite coating was prepared on the surface of annealed 45 carbon steel by double-pulse electrodeposition. The effect nanodiamond particle content morphology, grain size and wear corrosion resistance were investigated. According to analysis test results X-ray diffractometry scanning electron microscopy, it found that cathodic polarization electrodeposition process enhance...

The nickel-manganese (Ni-Mn) alloy coating prepared from DC electrodeposition process in sulphamate bath was studied. The effects of process parameters, such as current density and electrolyte composition, on the cathodic current efficiency, microstructure, internal stress and mechanical properties were investigated. Because of its crucial effect on the application to the electroforming of micr...

A rational understanding of what occurs during electrocrystallization, defined at a nanolevel, is developed to control electrodeposition processes. The electrokinetic behavior of the elements in solutions and the electrodeposits structure resulting from the electron exchange reaction at the cathodic surface are taken into consideration and compared. Transient electrokinetic parameters are measu...

In this work, we report on the development of a palladium-based, microfabricated point-of-care electrochemical sensor for the determination of manganese using square wave cathodic stripping voltammetry. Heavy metals require careful monitoring, yet current methods are too complex for a point-of-care system. Voltammetry offers an attractive approach to metal detection on the microscale, but tradi...

The basic calcium phosphate mineral, hydroxyapatite (HAP) (Ca10(PO4)6(OH)2)), is the prototype of one of the major constituents of bone and teeth. Thin layers of HAP were coated on the surface of type 316L stainless steel by electrophoretic deposition (EPD) from a 2.5% suspension in isopropyl alcohol, and this was followed by vacuum sintering at 800uC for 1 h. The development of HAP coatings wa...

Functionalization of colloidal particles based on the use of polyelectrolytes and heterocoagulation was combined with electrophoretic deposition (EPD), with the aim of depositing titania-polystyrene (TiO(2)-PS) composite particles on Ti6Al4V substrates. The composite particles were obtained by heterocoagulation of TiO(2) nanoparticles on the surface of monosized polystyrene beads of 4.6 microm ...
