Interfacial Phenomena Research



Interfacial phenomena research is centered on the fundamental interactions between a thin film, its vapor, and a solid substrate.  Most of the work is focused on thin liquid films, although we also work on the stability of thin solid films too.  Below I list the various research projects we have in this area.






Stability of Thin Solid Films  -  research in this area is focused on how initially contiguous thin solid films either buckle or break up and agglomerate when deposited on solid or nanoporous substrates.  We are also interested in how films roughen and develop a particular microstrcuture during deposition and growth.

Roughness Evolution and Growth of a-Si





Thin Liquid Films  -  research in this area is focused on how thin liquid films on surfaces behave.  The work is supported by NASA and forms the basis of a microgravity flight experiment, the first such experiment to be flown on the International Space Station.  Of particular interest are contact line dynamics when phase change is occurring.  Projects in this area include:


Image Analyzing Interferometry

Drop Dynamics During Evaporation and Condensation

Effect of Surfactants on Contact Line Dynamics During Spreading

Contact Line Stability During Evaporation and Condensation

Thin Film Draining Processes

Miniature Heat Pipe Systems
