Contraction of surfactant-laden pores

The contraction of surfactant-laden pores at the microscale has implications fornatural and technological processes ranging from the collapse of channels in lipid mem-branes to the stability of foams in the food processing industry. Despite its prevalence,our understanding of the mechanisms of pore...
