The paper describes the physics of particle adsorption and the spontaneous dispersion of powders that occurs when they come in contact with a fluid-liquid interface. The dispersion can occur so quickly that it appears explosive. especially for small particles on the surface of mobile liquids like water. Our PIV measurements show that the adsorption of a spherical particle at the inter... https://www.ealisboa.com/limited-stock-Purple-House-Arrethe-Bush-Balm-Soap-quick-super/
