Title

Dynamics of water confined inside inside inorganic nanotubes with variable hydrophilicity: a continuation

Abstract

Imogolite Nanotubes (INT) of interest for our team are inorganic nanotubes having an inner diameter of ~1 to 3 nm, with nominal formula (OH)3Al2O3Ge(A) — from the outside surface to the core surface of the nanotube. Changing the internal group A=[OH, CH3] allows to vary the hydrophilicity of the inner surface of the tube (modification of water-surface interactions). Our objective with these versatile nanochannels is to obtain a consistent set of new data about the multiscale dynamics of water in model nanoporous media with variable hydrophilicity. In this continuation proposal, we want to focus on the melting process of the inner hydration layer, in strong interaction with the inner surface of the nanotube. For that we want to use IN16B to understand the microscopic diffusion mechanism of this hydration layer.
