"Wetting and Spreading Behavior of Liquids under Nanoscale Confinement"


The wetting and spreading behavior of liquids at the nanometer scale is strongly influenced by microscopic effects such as van der Waals and structural forces and thermal fluctuations of the liquid free surface. Understanding these phenomena is important not only from a fundamental standpoint but also for emerging technologies. Research in this field is fostered by advancements in nano-patterning techniques which allow surfaces with well-defined chemical and or geometrical nanostructures to be routinely fabricated. These nanostructures act as liquid "nano-containers" and therefore provide model systems to study the wetting and spreading behavior under nano-confinement. In this talk, I will present atomic force microscopy and x-rays scattering studies of wetting and spreading on nanostructured surfaces. The results of this research provide valuable insight into the wetting and spreading behavior of nanoliquids and a stringent test for available theories.
