Nanowetting:
Liquid-Solid Interaction at the Nanometer Scale
Nanoscale
science and technology has the potential to transform processes
involving liquids in various industries. However, a combination
of suitable experimental techniques and computational methods is
needed in order to reveal the fundamentals of surface wetting
phenomena at the nanoscale. Specifically, the understanding of
liquid-solid interaction at the nanoscale is hoped to improve
existing oil reservoir models up to the macroscale with
potential benefits for enhanced oil recovery. -

In this seminar, I will present results obtained
with a novel measurement platform that enables the nanoscale
characterization of tiny amounts of liquids having volumes of
the order of 10 attoliter. The analysis of high-resolution
optical and topographical data measured on the same oil droplet
reveals how droplet shape and surface wetting behavior are
influenced by local properties of the surface. The experimental
results are compared with results obtained by molecular dynamics
simulations which take into consideration the properties of the
local chemical environment. I will discuss the future direction
of this research and how the results could be applied in the
domain of natural resources management.
