The acid-base properties of oxides are well described by the surface complexation model, which superposes a thermodynamic description of acid-base reactions at the oxide surface with a double-layer model of the electrostatics at the solid-solution interface. So far, however, this model has not been extended to include the effects of permanent charges such as result, for example, from isomorphic...

We show that the first law for rotating Taub-NUT is straightforwardly established with surface charge method. The entropy explicitly found as a charge, and its value not proportional to horizon area. conclude there are unavoidable contributions from Misner strings charges, still, mass angular momentum gets standard values. However, no independent charges associated strings.

Surface charges at the inner leaflet of the plasma membrane may contribute to regulate the surface recruitment of key signaling factors. Phosphatidylserine (PS) is an abundant charged lipid that may regulate charge distribution in different cell types. Here we characterize the subcellular distribution and function of PS in the rod-shaped, polarized fission yeast. We find that PS preferably accu...

By using suitably improved surface integrals, we give a unified geometric derivation of the generalized Smarr relation for higher dimensional Kerr black holes which is valid both in flat and in anti-de Sitter backgrounds. The improvement of the surface integrals, which allows one to use them simultaneously at infinity and on the horizon, consists in integrating them along a path in solution spa...
