DOI: 10.1016/j.colsurfa.2016.11.018
Abstract: Abstract To elucidate the puzzling surface structure of hydrophilic colloidal particles of metal oxides dispersed in aqueous solutions, we reanalysed seemingly anomalous coagulation kinetics experiments carried out by various authors on nonporous as well as… read more here.

DOI: 10.3390/polym10040432
Abstract: The equilibrium volume of a polyelectrolyte gel results from a balance between the tendency to swell caused by outbound polymer/counterion diffusion along with Coulomb interactions on the one hand; and, on the other, the elastic… read more here.
