Междисциплинарный семинар | 25 Май 2026

Sonochemistry has evolved into a powerful and versatile technique based on the use of ultrasonic irradiation to induce chemical transformations through acoustic cavitation. This phenomenon generates localized extreme conditions, enabling the formation of reactive species and driving unique physicochemical processes. In this seminar, a comprehensive overview of the fundamental principles of sonochemistry is presented, including cavitation dynamics, radical formation, and the influence of key operational parameters. Special attention is given to the evolution of sonochemistry from early applications to its current role in advanced materials synthesis.

The second part of the talk focuses on recent research on the sonochemical synthesis of SiO₂–TiO₂-based nanostructures, highlighting the relationship between ultrasonic parameters and material properties such as morphology, hydrophobicity, photocatalytic activity, and antimicrobial performance. The coupling of sol–gel methods with sonochemical energy is discussed as an effective strategy for designing multifunctional materials. Finally, current challenges in scalability and process control are addressed, along with future perspectives for the integration of sonochemistry in sustainable and industrial applications.
