Preparation of stable suspensions of gold nanoparticles in water by sonoelectrochemistry

Ultrasonics Sonochemistry, 2008
Stable suspensions of gold nanoparticles in water were prepared with high yield by a novel one-step ultrasound assisted electrochemical process. Various strategies based on the addition of either tailor-made polymers or mixtures of commercially available polymers, in the electrochemical bath have been found successful to avoid nanoparticles aggregation

Calcium phosphate powder synthesis by out-of-phase pulsed sonoelectrochemistry

Ultrasonics Sonochemistry, 2019
High aspect ratio calcium phosphate (CaP) nanorods were achieved by out-of-phase pulsed sonoelectrodeposition from electrolytic aqueous bath composed of calcium nitrate, ammonium dihydrogenophosphate and surfactant at pH of 4.9. The nature of CaP phases was determined by powder X-ray diffraction (PXRD), Fourier transform infrared spectroscopy (FTIR ...

Acoustically‐Induced Water Frustration for Enhanced Hydrogen Evolution Reaction in Neutral Electrolytes

Advanced Energy Materials, Volume 13, Issue 7, February 17, 2023., 2023
Employing high‐frequency (10 MHz) electroacoustic waves in electrochemistry for the hydrogen evolution reaction (HER) redefines the use of traditionally poor catalysts in challenging neutral conditions. The electroacoustic waves induce “water‐frustration” of the electrolyte coupled with efficient convective mass transport, bubble growth suppression and

A Modulation QCM Applied to Copper Electrodeposition and Stripping

Electroanalysis, Volume 33, Issue 12, Page 2529-2538, December 2021., 2021
Abstract A fast electrochemical quartz crystal microbalance with dissipation monitoring (EQCM−D) was applied to copper electrodeposition and subsequent stripping. Accumulation brings the frequency noise down to the mHz range, corresponding to 0.1 % of a monolayer.
