Carbon nanotube (CNT) is an attractive material for needle-like conducting electrodes because it has high electrical conductivity and mechanical strength. However, CNTs cannot provide the desired properties in certain applications. To obtain micro- and nanoneedles having the desired properties, it is necessary to fabricate functional needles using various other materials. In this study, functio...

Facile, cost-effective, and manufacturable techniques to create single-nanowire based devices with good electrical interconnects is demonstrated by combining template directed electrodeposition, magnetic assembly, and a post-annealing in a reducing environment. Nickel nanowires with a diameter of approximately 30 nm were electrodeposited from low-stress nickel sulfamate baths at room temperatur...

The combination of nanomaterials with electrode materials has opened new horizons in electroanalytical chemistry, and in electrochemistry in general. Over the past two decades we have witnessed an enormous activity aimed at designing new electrochemical devices based on nanoparticles, nanotubes or nanowires, and towards the use of electrochemical routes--particularly template-assisted electrode...

Bismuth and antimony are semimetals with a rhombohedral crystal structure and similar lattice parameters. Bi12xSbx alloys exhibit unusual electronic properties and are of interest for thermoelectric and magnetoelectronic devices. In this paper, we show that Bi12xSbx alloys can be electrodeposited from acidic chloride-based solutions and that a homogenous solid solution is obtained across the en...

In this study, electrochemical deposition of Ni-SiC-Gr nano composites was studied. The Watts bath was used for electrodeposition. The SiC and graphite powders were suspended in the electrolyte and stirred. The effects of changes in bath stirring rate on the composite coating were investigated. The X-Ray diffraction (XRD), scanning electron microscopy (SEM) and field emission scanning electron ...

Tremendous potential exists for the growth of metal finishing industry in this century through the development of processes that are either environmentally friendly or are applicable at the nano scale. In the CEE the theoretical and experimental studies are performed to achieve such coatings. Nanostructured alloys and innovative composite materials were developed through adaptation of existing ...

In this work, we report on the electroplating of ultrafine and uniform magnesium (Mg) films on copper (Cu) and carbon nanotube (CNT) paper substrates. By controlling the process parameters and utilizing the pulsed deposition method, the average grain size of Mg was reduced to nanodimensions. Surface pretreatment of the substrates by depositing a seed layer was found to be an efficient strategy ...

background: due to the potential public health effects of releases of uranium to the environment, isotopic determination and measurement of this radionuclide in environmental samples is very important. achieving this goal, monitoring programs for this radionuclide seems necessary to be applied in many countries. materials and methods: the uranium was separated from the water samples using anion...

ni-co/cu multilayers have been grown by electrodeposition method from a single electrolyte (based on ni(so4).6h2o, co(so4).7h2o, cu(so4) and h3bo3) using galvanostatic control on titanium sublayers. the x-ray diffraction (xrd) patterns confirmed the multilayered structure with the nanometer thicknesses. also, electron diffraction x-ray (edx)  analysis confirmed the purity of deposited samples. ...

Abstract YAG (Yttrium Aluminum Garnet) was successfully prepared through cathodic electrodeposition process using applying different current densities to the mixture of YCl3 and AlCl3 dissolved in water/ethanol 1:1 solution. Hydroxide precursors were cathodically grown on the cathode surface (at different current densities) and then the obtained hydroxide powder was heat-treated at 1100 °...
