An introduction to sonochemistry
, 1989 Although the effect of ultra high-frequency sound waves on chemical reactions was recorded more than 60 years ago it is only during the last two decades that sonochemistry has become an important field of research in its own right.

Infrared Photovoltaic–Battery Hybrid Systems Enabled by Colloidal Quantum Dots
Chemistry – An Asian Journal, Volume 20, Issue 21, November 3, 2025.Photovoltaic–battery (PV/B) hybrid systems are key for sustainable energy but face cost and efficiency limits. Colloidal quantum dots (CQDs) enable low‐cost near‐infrared light harvesting, surpassing silicon and III–V PVs. This review analyzes CQD properties, their roles in NIR PVs and batteries, and synthesizes current research to highlight progress ...

Sonochemistry and sonoprocessing:the link, the trends and (probably) the future
, 2003 Traditionally the community of scientists involved with ultrasound has been divided broadly into those who use it as a measurement device with no effect on the medium (high frequency low power ultrasound e.g. non-destructive testing) and those who use it

Particle &Particle Systems Characterization, Volume 42, Issue 11, November 2025.Here it is revealed how ultrasonic dispersion chemically and structurally alters Pt/C catalysts depending on carbon black type. While high surface area carbons remain stable, low and medium surface area carbons undergo oxidation, increasing charge‐transfer resistance and degrading fuel cell performance.

Sonochemical activation for BaTiO3 synthesis: A rapid and efficient route to the tetragonal phase
International Journal of Applied Ceramic Technology, Volume 22, Issue 6, November/December 2025.Abstract Barium titanate is a highly promising ferroelectric material, but its synthesis is often based on lengthy and complex processes. This paper presents the development of an ultrafast synthesis route for producing high‐purity tetragonal BaTiO3. The method combines a brief sonochemical activation (15 min) with conventional calcination. Compared to
