Characterization of materials at interfaces includes
also transfer processes taking place there. This is an ubiquitous
phenomenon in the environment, technical processes, and living
species. Because at least one of the two phases at the interface is
mobile, these processes are characterized by a complex interplay
between molecular diffusion and turbulent transport. In this paper,
a new technique is introduced for fluorescence imaging of
the mass transfer across the air-water interface.
