Experimental Studies of Phase Transitions and Pattern Formation in Two Dimensions
The technique of fluorescence microscopy has been utilized in studies of the equilibrium phase behavior and the kinetics of phase transitions and pattern formation in monolayers at the air/water interface. A brief description of the equilibrium phase diagram of fatty acid monolayers is presented and quantitative studies of the evolution of two-dimensional gas-liquid foam structures in such systems are reported. Shape instabilities observed in monolayers of esters are described qualitatively.
