Query: Complex High Internal-Phase Emulsions that can Form Interfacial Films
  with Tuneable Morphologies   High internal phase emulsions (HIPEs) are considered as an important
functional material and have been the focus of intense development effort, but
it has not been possible to alter their fundamental attributes at either the
microcosmic or macroscopic level, which severely limits their practical
applications in various areas. In this work, we report a general strategy for
creating complex HIPEs and we additionally show a route to forming HIPE films
at liquid interfaces. Double HIPEs and Janus HIPEs are both realized for the
first time. They feature complex microscopic patterns with a short-range
anisotropy, and exhibit non-Newtonian pseudoplastic flow behavior. By taking
advantage of their response to a high-pH subphase, interfacial films can be
successfully obtained, which are tunable in thickness and morphologies under
compression.
