Ultrastable Particle‐Stabilized Foams

Pump up the volume: Wet foams prepared with surfactants are thermodynamically unstable systems that undergo rapid disproportionation, drainage, and coalescence. Ultrastable foams have now been prepared using colloidal particles as stabilizers (left picture). The stabilization results from the irreversible adsorption at the air–water interface of particles surface-modified with short-chain amphiphiles (right picture).
