The authors wish to thank Dr. Junqi Ding for assisting with the design and setup of our BAM system. We also thank Professor Michael Dennin and Professor Elizabeth Mann for useful discussions that brought to our attention the importance of coexisting phase domains in Langmuir monolayers and their possible effects on interfacial hydrodynamics. This work was partially supported by the National Science Foundation.

N2 - Monolayer hydrodynamics are usually described in terms of a Newtonian constitutive relationship. However, this macroscopic view fails to account for small-scale coexisting phase domains, which are generally present in the monolayer and appear to have profound macroscopic effects. Here, we provide direct evidence of these effects, consisting of Brewster angle microscopy images of the monolayer, space- and time-resolved interfacial velocity measurements, and comparisons with predictions based on the Navier-Stokes equations together with the classic model for a Newtonian interface.
