Abstract
Fundamental understanding of the unique physics at the solid-liquid interface in nanofluidic channels is essential for
the advancement of basic scientific knowledge and the development of novel applications for pharmaceuticals, environmental
health and safety, energy harvesting and biometrics [1]. The current models used to describe surface phenomena in
nanofluidics can differ by orders of magnitude from experimentally measured values [2]. To mitigate the discrepancies, we
hypothesize that the Stern-layer capacitance Cs and the surface equilibrium constants pKa, vary with the composition of
the solid-liquid interface. We quantify these dependencies combining theoretical modeling and nanofluidic capillary filling
experiments.
