Existing research on human channel modeling of galvanic coupling intra-body communication (IBC) is primarily focused on the human body itself. Although galvanic coupling IBC is less disturbed by external influences during signal transmission, there are inevitable factors in real measurement scenarios such as the parasitic impedance of electrodes, impedance matching of the transceiver, etc. whic...

Magnesium-based wastes were reprocessed by mechanical milling under air atmosphere and used to produce hydrogen hydrolysis on a laboratory scale. The evolution of the material during reprocessing generation in 0.6 M MgCl2 aqueous solution at 24 °C are reported. morphology, microstructure phase abundance change with time. During processing, (i) particle size crystallite reduce, (ii) microstrain ...

This paper discusses chemical and galvanic corrosion of tungsten nitride carbide (WNC) barrier metal. Chemical corrosion occurs due to the oxidation of W in the WNC film by H2O2, which is used as oxidizer in CMP slurries, followed by the dissolution of the oxide complex. Galvanic corrosion takes place due to the high potential difference between Cu and WNC established in the presence of H2O2 ba...

While galvanic exchange is commonly applied to metallic nanoparticles, recently its applicability was expanded to metal-oxides. Here the galvanic exchange is studied in metal/metal-oxide core/shell nanocrystals. In particular Sn/SnO2 is treated by Ag+, Pt2+, Pt4+, and Pd2+. The conversion dynamics is monitored by in situ synchrotron X-ray diffraction. The Ag+ treatment converts the Sn cores to ...

Coupling seed-mediated co-reduction with galvanic replacement for the first time provides a route to trimetallic (Ag-Au-Pd) nanostructures with hollow interiors. Moreover, manipulating the synthetic conditions can suppress galvanic replacement and facilitate formation of trimetallic core@shell (Ag@Au-Pd) nanostructures. These results illustrate the role of seed composition in the synthesis of a...

In this study, three-dimensional gold-nickel-molybdenum (Au(NiMo)) catalysts have been studied as for the oxygen evolution reaction (OER). The deposited on a titanium surface using electroplating and galvanic displacement techniques. modification of NiMo with low amount Au crystallites in range 1.2– 5.2 μgAucm–2 results enhanced activity OER alkaline medium compared to respective binary un-modi...

A 3D porous Ag-Bi electrode was developed to achieve the highly selective reduction of CO2 into formate. Ag particles were deposited on Bi coated graphite felt by galvanic displacement reaction. The selectivity enhanced with compared felt. bimetallic catalytic system converted formate a high 88% at -1.6 VSCE. structure and large surface area facilitated mass transport, leading current density 7...

Bimetallic nanostructures with non-random metal atoms distribution are very important for various applications. To synthesize such structures via benign wet chemistry approach remains challenging. This paper reports a synthesis of a Au/Pd alloy nanostructure through the galvanic replacement reaction between Pd ultrathin nanowires (2.4 +/- 0.2 nm in width, over 30 nm in length) and AuCl3 in tolu...
