At pH >pHzpc the superficial charge is negative, favoring cation adsorption.
When superficial charge is considered, liposomes can be neutral or charged.
The surface stress response is quantified by means of the electrocapillary coupling parameter, ς, defined as the derivative of f with respect to the superficial charge density.
Since there are different kinds of chitosan, obtained from different sources of chitin and routes, it is very important to study which are the best conditions in order to obtain nanoparticles with desired size and superficial charge.
The decrease of superficial charge of liposomal formulations containing Ac-SOD, as compared to SOD liposomes, may be related to the negatively charged enzyme molecules localized on the liposome surface.
According to the pHpzc of the adsorbent (pHpzc = 7), at the pH of the adsorbate solution chosen (5.5 6.0), the superficial charge of the adsorbent is still positive and it is not so much as at pH 2; this could explain the low sorption capacity of the adsorbent.

The anchoring layer of PEI led a positive superficial density charge onto the fiber so that each bilayer shows the structure PSP/PAH.
Could Leslie's expression of remorse remain "superficial," as was charged in her 2003 parole hearing?
If true, they wrote, then variation at a single, tiny genetic locus in charge of "superficial traits" had been "the cause of enormous suffering".
In addition, in the case of a 100 g blast charge, the superficial damage of the SCC panel was improved by hybrid with PVA or PE fibers, as the fracture energy of the PVASCC and PESCC was significantly higher than that of the SCC.
An optimal superficial current density and charge yield of 971 A m−2 and 0.58, respectively, were obtained at −1.62 V (AgCl∣Ag) and 99 ml min−1 solution flow rate; current densities were increased by a factor of 27 compared with the behaviour of a 2D electrode.
