Bubble-particle interaction is of great theoretical and practical importance in flotation.
Significant progress has been achieved over the past years and the process of bubble …

Gas bubbles widely exist in nature and numerous industrial processes. The
physicochemical characteristics of bubbles such as large specific surface area, low density …

The word tribology originates from the Greek word tribos, which means “friction, rub,
grind,”“to wear away,” or “science of friction.” Tribology is the study of science and …

The use of atomic force microscopy to measure and understand the interactions between
deformable colloids–particularly bubbles and drops–has grown to prominence over the last …

Wet and dry foams are prevalent in many industries, ranging from the food processing and
commercial cosmetic sectors to industries such as chemical and oil-refining. Uncontrolled …

The hydrophobic attraction describes the well-known tendency for nonpolar molecules and
surfaces to agglomerate in water, controlled by the reorganization of intervening water …

Superhydrophobic surfaces are usually characterized by a high apparent contact angle of
water drops in air. Here we analyze the inverse situation: Rather than focusing on water …

Oil-in-water emulsions stabilized by graphene oxide (GO) can be flocculated by either an
increase or a decrease in pH. At highly acidic pH, fully reversible flocculation of emulsion …

Compound drops arise from the contact of three immiscible fluids and can assume various
geometric forms based on the interfacial chemistry of the phases involved. Here we present …

The hydrophobic force describes the attraction between water-hating molecules (and
surfaces) that draws them together, causing aggregation, phase separation, protein folding …
