Investigating the Ubiquitous Presence of Nanometric Water Films on Surfaces at the Nanoscale

When we speak of nanometric water films on surfaces we are speaking about a truly ubiquitous phenomenon in nature. All surfaces exposed to ambient conditions are covered by a thin film of water that affects or mediates surface chemistry, general physical-chemical processes on surfaces, and even solid-solid interactions. We have investigated this phenomenon for over a decade by exploiting dynamic atomic force microscopy and x-ray photoelectron spectroscopy. I will discuss the different technical approaches that we have been using to study water on surfaces at the nanoscale and our finding on a wide range of materials and applications from graphene, to ferroelectric oxides, ionic crystals, etc. Finally I will describe our recent lines centered on the study of surfaces to promote ice nucleation.
