International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012 Chromatographic techniques are among the most useful analytical methods. Gas and liquid chromatography were used in the analysis of some organic compounds: phenol, hydroquinone, benzoquinone, and maleic and fumaric acids. The analytical way for the determination of these compounds in water samples was investigated.

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.

cScience, Volume 1, Issue 1, December 2025.ABSTRACT This study investigated the sequestration of CO2 from flue gas using a Ca‐rich leachate obtained by leaching steel slag with CH3COOH. Ultrasound was used to accelerate the fixation of low‐concentration CO2 in the leachate and to induce the transformation of CaCO3 crystals into the vaterite form with a uniform particle distribution.

Tungsten Nanoparticles Generated in an Atmospheric Pressure Plasma Jet
Particle &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 ...

Reactive Magnesium Nanoparticles to Perform Reactions in Suspension
Chemistry – 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
Ultrasonics 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 ...

Sonoelectrochemistry in Acoustically Emulsified Media: The Detection of Lead
Electroanalysis, 2003 AbstractThe double extraction of target lead ions which are then voltammetrically quantified via acoustically assisted anodic stripping voltammetry is demonstrated. The technique involves first the extraction of lead from the aqueous volume into an organic phase containing the ligand dithizone (diphenylthiocarbazone).
