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!

Sonication Enables a New Level of Control in Cellulose Nanocrystal Self-Assembly
, Kathrin HielscherSonication holda the key to unlocking more reliable, scalable production of cellulose nanocrystal (CNC) materials. A new study reveals that sonication doesn’t just break up CNC clusters – it actively reshapes how these sustainable nanomaterials self-assemble into cholesteric liquid crystal structures responsible for brilliant structural color. By observing CNC ordering inside tiny evaporating droplets, researchers found that ultrasound can delay gelation, shift kinetic arrest, and tune the helical pitch evolution with remarkable precision. The findings highlight sonication as an industrially relevant processing lever for programming reproducible CNC-based photonic coatings and advanced bio-based materials at scale.
