Whereas previously a dense monolayer was believed to be required for such an "armored bubble" to resist dissolution, in fact engineering a 2D yield stress interface suffices to achieve such performance at submonolayer particle coverages. We use a suite of interfacial rheology techniques to characterize spherical and ellipsoidal particles at an air-water interface as a function of surface coverage. Bubbles with varying particle coverages are made and their resistance to dissolution evaluated using a microfluidic technique. Whereas a bare bubble only has a single pressure at which a given radius is stable, we find a range of pressures over which bubble dissolution is arreProceedings of the National Academy of Sciences of the United States of AmericaArresting dissolution by interfacial rheology design.PMC5625905200021165974200021_165974Vermant JLiascukiene IBaroud CNBeltramo PJGupta MGunes DZAlicke AfalseArresting dissolution by interfacial rheology design.A strategy to halt dissolution of particle-coated air bubbles in water based on interfacial rheology design is presented.
