Ultrafine bubble characterization

Introduction Ultrafine bubbles are defined by their size (less than 1 ┬Ám), they offer additional features compared to ordinary bubbles: they stay longer in a liquid and lower the surface tension. Their properties have long been used but the technology keeps on expanding to new applications in various fields such as toilet detergency, cosmetics, medical, semi-conductor, and agriculture for vegetables growing acceleration. The challenge is the detection and characterization of these very fine bubbles to highlight their efficiency. Static Multiple Light Scattering is proposed to monitor ultrafine bubble stability in water, but also to determine bubble size and concentration.
