Influence of Bubbles on the Energy Conversion Efficiency of Electrochemical Reactors [PDF]

open access: yes, 2020
Bubbles are known to influence energy and mass transfer in gas evolving electrodes. However, we lack a detailed understanding on the intricate dependencies between bubble evolution processes and electrochemical phenomena.

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.

Studies in sonoelectrochemistry

open access: yes, 2016
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.

Sonochemical and Sonoelectrochemical Production of Hydrogen - A Review [PDF]

open access: yes, 2018
Reserves of fossil fuels such as coal, oil and natural gas on earth are finite. The continuous use and burning of these fossil fuel resources in the industrial, domestic and transport sectors has resulted in the extremely high emission of greenhouse ...

Tungsten Nanoparticles Generated in an Atmospheric Pressure Plasma Jet

open access: yesParticle &Particle Systems Characterization, Volume 41, Issue 9, September 2024.
The study demonstrates the successful synthesis of pure tungsten nanoparticles using the HelixJet atmospheric plasma source. By heating a tungsten wire in an argon plasma without oxygen, evaporation of tungsten and the subsequent condensation of metal vapour in the gas stream are achieved, leading to nanoparticles with controlled size and morphology ...

Procédés d’oxydation avancée dans le traitement des eaux et des effluents industriels: Application à la dégradation des polluants réfractaires [PDF]

open access: yes, 2009
Cette synthèse traite des procédés d’oxydation avancée (POA) pour le traitement des eaux et des effluents industriels. Ces procédés mettent pour la plupart en combinaison deux ou trois réactifs (oxydants) afin de produire des radicaux hydroxyles.

Reactive Magnesium Nanoparticles to Perform Reactions in Suspension

open access: yesChemistry – A European Journal, Volume 30, Issue 35, June 20, 2024.
Magnesium nanoparticles (10.3±1.7 nm) are prepared in THF. Based on their high reactivity, they are used as a starting material in the liquid phase for reaction with sterically demanding ligands, resulting in C−C and Si−Si coupling reactions and five novel coordination compounds.

Mercury-electroplated platinum electrodes and microelectrodes for sonoelectrochemistry

open access: yesUltrasonics Sonochemistry, 1995
Abstract The preparation of mercury-electroplated platinum disc electrodes of both micrometre and conventional dimensions from an aqueous solution of mercury(I) nitrate and potassium cyanide is described. The mercury film electrodes so produced led to very reproducible voltammetric results, as observed by the cathodic reduction of fluorescein to ...
