Query: Role of charge regulation and flow slip on the ionic conductance of
  nanopores: an analytical approach   The number of precise conductance measurements in nanopores is quickly
growing. In order to clarify the dominant mechanisms at play and facilitate the
characterization of such systems for which there is still no clear consensus,
we propose an analytical approach to the ionic conductance in nanopores that
takes into account (i) electro-osmotic effects, (ii) flow slip at the pore
surface for hydrophobic nanopores, (iii) a component of the surface charge
density that is modulated by the reservoir $p$H and salt concentration $c_s$
using a simple charge regulation model, and (iv) a fixed surface charge density
that is unaffected by $p$H and $c_s$. Limiting cases are explored for various
ranges of salt concentration and our formula is used to fit conductance
experiments found in the literature for carbon nanotubes. This approach permits
us to catalog the different possible transport regimes and propose an
explanation for the wide variety of currently known experimental behavior for
the conductance versus $c_s$.
