Surface Charge Mapping with a Nanopipette [PDF]
Journal of the American Chemical Society, 2014 Nanopipettes are emerging as simple but powerful tools for probing chemistry at the nanoscale. In this contribution the use of nanopipettes for simultaneous surface charge mapping and topographical imaging is demonstrated, using a scanning ion conductance microscopy (SICM) format.

Interaction between heterogeneously charged surfaces: Surface patches and charge modulation [PDF]
Physical Review E, 2013 When solid surfaces are immersed in aqueous solutions, some of their charges can dissociate and leave behind charge patches on the surface. Although the charges are distributed heterogeneously on the surface, most of the theoretical models treat them as homogeneous.

Simulating Surface Charge Dynamics [PDF]
IEEE Transactions on Dielectrics and Electrical Insulation, 2021 Surface charge dynamics can play an important role in electric field distributions in both AC and DC insulation systems. In this paper the theory behind surface charge dynamics is introduced with a particular focus on the calculation of surface divergence; an operator which is used to determine movement of charge constrained to a surface.

Buried Charged Surface in Proteins [PDF]
Structure, 2000 The traditional picture of charged amino acids in globular proteins is that they are almost exclusively on the outside exposed to the solvent. Buried charges, when they do occur, are assumed to play an essential role in catalysis and ligand binding, or in stabilizing structure as, for instance, helix caps.By analyzing the amount and distribution of ...
