Coating Fabrication: Hydrodynamically Formed Uniform Thick Coatings on Microspheres (Small 23/2018)

In article number 1800613, Haosheng Chen and co-workers fabricate highly uniform thick coatings encapsulating microspheres. Heavy microspheres loaded in a rolling emulsion droplet (density ratio of the microspheres to droplet over 5) driven by the continuous flow in a pipe can be lifted to the center of the droplet against gravity by the hydrodynamic force generated in the lubrication film circulating around, whereas the microspheres sit on the floor with a calm encapsulating emulsion layer.
