Boosting effect of ultrasonication on the oxygen evolution reaction during zinc electrowinning [PDF]

open access: yesUltrasonics Sonochemistry
In this study, the electrochemical and anodic behaviors of Pb-Ag anodes during ultrasound-assisted zinc electrowinning were meticulously examined. The oxygen evolution reaction (OER) occurring at the Pb-Ag anodes in a 150 g L-1 aqueous H2SO4 solution was

Production of Metal Nanopowders by Sonoelectrochemistry

open access: yesMRS Proceedings, 1994
AbstractMetal powders with a diameter ranging from 20 to 50 micrometers are currently produced by electrolysis at high current density in aqueous electrolytes. A lot of research is then devoted to produce by electrolysis and with a high yield, ultrafine metal powders.

Sonoelectrochemistry

open access: yesUltrasonics, 1990
The factors which make power ultrasonic irradiation such a powerful tool in promoting chemical reactivity in liquids at solid surfaces include continuous surface cleaning, degassing and improved mass transport. For many years metallurgists have harnessed

Studies in sonoelectrochemistry [PDF]

open access: yes, 1999
The work described in this thesis employs 'dual activation' methodologies and in particular sonovoltammetry to study a variety of electrochemical systems. First, the effect of 20 kHz power ultrasound on the electrochemistry of simple redox systems in both water and acetonitrile is explored and characterised for different cell geometries.

Sonoelectrochemistry: Both a tool for investigating mechanisms and for accelerating processes

open access: yesThe Electrochemical Society Interface, 2018
Surface irradiation by power ultrasound has proven to offer beneficial effects not only for surface cleaning, but also for the modification of functional properties of metallic or organic coatings.

Sonoelectrochemistry in acoustically emulsified media

open access: yesJournal of Electroanalytical Chemistry, 2002
Abstract The physical processes giving rise to sustained electrolytic currents within sono-emulsions are explored and shown to arise from: (i) the ‘thinning’ of the diffusion layer at the active electrode and in particular (ii) the release of dissolved material from the suspended phase within the diffusion layer.

Methods of synthesis of nanoparticles and their dimensionsensitive physical parameters

open access: yesТонкие химические технологии, 2010
The varieties of the methods of nanoparicles synthesis are discussed in this review. Wet and dry chemistry processes, pulse sonoelectrochemistry, methods with use of supercritical CO2, and far from equilibrium systems of two liquids are considered and ...
