Sonoelectrochemical measurements at macro-electrodes under extreme conditions with a very short distance between ultrasonic horn tip and electrode and different ultrasound intensity levels are shown to result in violent cavitation detected in form of

The suitability of ultrasound-assisted anodic stripping voltammetry (sono-ASV) for the detection of total copper content in beer using both mercury thin film and glassy carbon electrodes has been investigated. An immersion horn probe is introduced in

Sonotrodes were made by implanting a working electrode into the tip of an ultrasonic horn. These were investigated for the use in ultrasound assisted anodic stripping voltammetry (ASV) of Pb2+ and Cu2+ in aqueous solutions to which Hg2+ was added to

Modelling electrochemical processes at the three phase junction between electrode-aqueous electrolyte-oil droplet presents a considerable challenge due to the complexity of simultaneous electron transfer between electrode and droplet, ion uptake or e

Mercury electroplated onto solid electrodes is widely used for electrochemical measurements. Depending on the substrate, the coating can take the form of either a uniform thin film or an assembly of microdroplets. It is interesting to ask the extent

Anodic stripping voltammetry experiments were carried out in aqueous lead solution using square wave voltammetry at insonated mercury thin film electrodes and compared to numerical theory developed in an earlier paper (Ball, J. C.; Compton, R. G. J.
