Ultrasonic topic: "Common applications of Ultrasonic Dispersers"
Ultrasonic dispersers are a reliable tool to disperse and deagglomerate micron- and nano-sized particles into uniform suspensions. Besides the common dispersing application, ultrasonic dispersers (also known as probe-type ultrasonicators) are used for manifold other processes in lab and industry.
The application fields of ultrasonic dispersers include liquid-solid mixtures, emulsification, extraction, disintegration and cell lysis, sonochemical reactions and many more.
Common applications of ultrasonic dispersers are the production of stable nano-emulsions and -suspensions; sample preparation e.g. soil samples to identify the presence of polycyclic aromatic hydrocarbons (PAHs); degassing and deaeration of samples; as well as the functionalization, activation and cleaning of particle surfaces (e.g. catalysts).

Ultrasound Advances Phase-Change Materials for Energy Storage
, Kathrin HielscherResearchers are increasingly using high-power ultrasonic processing (sonication) to improve the performance of phase-change materials (PCMs) used in thermal energy storage. By generating intense cavitation and micro-mixing, ultrasound enables the production of stable PCM dispersions, nano-enhanced PCMs, and nanoencapsulated materials with superior heat transfer and long-term stability. Studies show that sonication produces more homogeneous mixtures and smaller particle aggregates compared to conventional mixing methods, leading to more reliable thermal behavior and improved energy storage performance.
Advanced ultrasonic processors, such as those developed by Hielscher Ultrasonics, provide precise control over cavitation intensity and processing parameters, making them powerful tools for PCM research and scalable industrial production. The technology is already being used to disperse nanoparticles, create paraffin wax emulsions, and fabricate micro- and nano-encapsulated PCMs, helping researchers develop next-generation materials for building climate control, renewable energy storage, electronics cooling, and battery thermal management.
How Ultrasonic Dispersion Improves Wet End Performance and Cuts Costs
, Kathrin HielscherPapermakers are discovering that better chemistry doesn’t always mean more chemistry. A growing number of mills are turning to ultrasonic dispersion to improve how wet end additives are mixed and activated before they ever reach the stock. By using high-power ultrasound to break up agglomerates and homogenize chemical streams in-line, mills can improve retention, formation, and process stability while reducing chemical consumption and energy use. With linear scalability and industrial-grade sonicator systems from Hielscher Ultrasonics, ultrasonic dispersion is moving from the lab into full-scale paper production as a practical, cost-effective wet end upgrade.
