Influence of pinning effects on the electrochemical formation of silver patterns in agarose-containing sols and gels

Article Abstract:

The formation of silver patterns namely, electrolysis from aqueous silver sulfate + x% w/v agarose sol and gel media, with and without supporting electrolyte, in a quasi-two-dimensional (2D) cylindrical cell at room temperature, is utilized as a reference system to investigate the complexity of pinning effects. From pattern morphology and electrochemical data, both delocalized and localized pinning in the bulk dominate the drift of the growth front, depending on the concentration of agarose in the heterogeneous media.

Early stages of NiO growth on Ag(001): a study by LEIS, XPS, and LEED

Article Abstract:

A study was conducted, using X-ray photoelectron spectroscopy (XPS) and low-energy ion scattering (LEIS), to investigate the composition and the growth mechanism of the phases formed in the early stages of nickel oxide deposition on Ag(001). The result shows that at O2 pressures in the 10(super -7)- 10(super -6) mbar range and sample temperatures between room temperature and 373 K, a nickel oxide layer forms showing a (2 x 1) low-energy electron diffraction (LEED) pattern.

Sieving effect of agarose on quasi-2D silver pattern electroformation: a pinning-depinning-like transition resulting from gelled silver plating solutions

Article Abstract:

The novel features of silver growth patterns, produced by quasi-2D electrochecmical cells of parallel-plate cathode-anode design, utilizing different plating baths under the form of agarose sols and gels, are presented. The morphology transitions in the silver growth patterns that depend on the composition of plating solutions are explained.
