zn-co electrodeposits have attracted interest because of their significantly higher corrosion resistance in comparison with pure zinc. in this research the influence of bath temperature and electrolyte’s co 2+ concentration on the morphology and composition of the zn-co coatings, electrodeposited on an aisi1018 steel substrate from a weakly alkaline glycine solutions, has been studied. sem and ...

When the dimension of materials decreases to mesoscale, their properties can change dramatically, depending on the boundary conditions imposed by the sample architecture including geometry, morphology, and hierarchical structures. Here we show that electrodeposition, a method for reducing materials from a solution onto a substrate, can provide a versatile pathway to tailor the architecture of m...

This paper describes the synthesis of low dimensional structures of copper by electrodeposition method using polycarbonate track etch membrane (PCTEM) as template. Copper microwires of different diameters were fabricated by using the membranes of pore diameters 0.2 & 0.4 um as template. The morphology of fabricated microwires was characterized by scanning electron microscope and material confir...

A patterned coreeshell tin (Sn) nanorod anode is fabricated by pulse electrodeposition of Sn onto a selfassembled Tobacco Mosaic Virus (TMV) structured nickel current collector. Pulse electrodeposition onto the virus assembled 3D electrode surfaces produces homogenous Sn coatings with significant void space to accommodate the large volume change associated with Sn lithiation. The TMV enabled 3D...

Nickel plated copper heat spreader acts as a medium to dissipate heat from silicon die towards heat-sink. Electroless nickel plating requires catalytic activation before the nickel can be deposited onto copper. Different catalytic activation techniques such as galvanic initiation and thin nickel-copper electrodeposition have diverse impact on the thermal performance of the heat spreader. Surfac...

Gold is determined in aqueous gold-containing drug solutions, 8 X 108 to 1 X 10 mol/liter, and in such drugs in serum, 2 X 106 to 1 X 10 mol/ liter, by electrodeposition onto a carbon paste electrode at -0.3 V vs. a saturated calomel electrode and subsequent stripping at constant current. Aqueous solutions are prepared for electrodeposition with a ceric perchlorate-hydrogen peroxide treatment. ...

We report the properties of a series of electrodeposited Ge-Sb-Te alloys with various compositions. It is shown that the Sb/Ge ratio can be varied in a controlled way by changing the electrodeposition potential. This method opens up the prospect of depositing Ge-Sb-Te super-lattice structures by electrodeposition. Material and electrical characteristics of various compositions have been investi...

A controllable flower-like Au nanostructure array for surface-enhanced Raman scattering (SERS) was fabricated using the combined technique of the top-down approach of conventional photolithography and the bottom-up approach of electrodeposition. Au nanostructures with a mean roughness ranging from 5.1 to 49.6 nm were obtained by adjusting electrodeposition time from 2 to 60 min. The rougher Au ...

Electrodeposition experiments of the charge-transfer complex copper tetracyanoquinodimethane (CuTCNQ) (where TCNQ denotes 7,7',8,8'-tetracyanoquinodimethane) on noble metal electrodes (M=Pt and Au) were optimized in order to produce suitable layers for bipolar resistive switching cross-bar M/CuTCNQ/Al memory cells. Corresponding memories exhibited up to more than 10 000 consecutive write/erase ...

Cu electrodeposition was performed on a cylindrical AZ80 substrate with a U-shaped surface. A uniform deposition of Cu was achieved on an AZ80 electrode via galvanostatic etching, followed by Cu electrodeposition in an eco-friendly alkaline Cu plating bath. Improper wetting and lower rotational speeds of the AZ80 electrode resulted in an uneven Cu deposition at the inner upper site of the U-sha...
