Ultra-Fine (nano) bubbles have garnered increasing interest over the last few years as they open up the potential for improvements in a variety of applications from cleaning to agriculture. However they are still somewhat a mystery with respect to their stability and longevity. This webinar covers the exciting and evolving landscape of ultra-fine bubbles and talk about their applications, the drive towards standardization in the arena along with some of the key process and characterization techniques. The characterization techniques covered is the Resonant Mass Measurement (RMM), Nanoparticle Tracking Analysis (NTA) and Dynamic Light Scattering (DLS)
