Anti-blistering

Single anti-blistering

Anti-blistering in the ring

A antibubble (English: Anti Bubbles ) is a spherical gas film, which contains both liquid and is surrounded by fluid (as opposed to a vesicle , which contains only gas and is surrounded by liquid).

In contrast to a form of emulsion, for example, there is a gas film between the surrounding liquid and the inside of the anti-bubble (which can also be identical).

Anti-blistering was first described in 1932 as a phenomenon observed when a bar of soap was immersed in water. The Belgian scientists Stéphane Dorbolo , Hervé Caps and Nicolas Vandewalle from the University of Liège created the bubbles in both beer and rinse water and described them scientifically in 2003 .

In 2005, the scientists Michiel Postema ( Ruhr University Bochum ), Nico de Jong (Erasmus MC, Rotterdam ) Georg Schmitz (Ruhr University Bochum) and Annemieke van Wamel (Erasmus MC, Rotterdam) presented high-speed recordings of anti-blister formation using ultrasound .
