Ultrasonic topic: "Ultrasonic Nanomaterial Processing"
High-performance sonication is a well-established technique for particle size reduction in nano-sized dispersions and emulsions. Besides the fine-size distribution of particles, ultrasonic processors are used to synthesise nano-structured materials such as nanodiamonds or to precipitate nanoparticles (e.g. magnetite (Fe3O4)).
Hielscher’s ultrasonic processors are available from lab to industrial size and can be used for batch and continuous inline sonication. Learn how sonication can improve your nano-material processing!

Ultrasonic Dispersing and Deagglomeration
The dispersing and deagglomeration of solids into liquids is an important application of power ultrasound and probe-type sonicators. Ultrasonic cavitation generates extraordinarily high shear that breaks particle agglomerates into single dispersed particles. Due to its locally focused high shear forces,…
