Ultrasonication is a process that uses high-frequency sound waves, typically above 20 kHz, to agitate particles in a liquid. This agitation creates microscopic bubbles that collapse violently, producing intense energy and heat. This phenomenon, known as cavitation, can help in various applications, such as mixing, emulsifying, and breaking down materials. In laboratories and industrial settings, ultrasonication is often used to enhance chemical reactions, improve extraction processes, and disperse nanoparticles. It is a valuable technique in fields like chemistry, biotechnology, and materials science, where precise control over particle size and distribution is essential for optimal results.
