The pH-dependent surface charging and the points of zero charge.
TL;DR: The recently published points of zero charge of metal oxides and related materials are compiled to update the previous compilation, finding the purity of materials is the most important factor responsible for discrepancies in the literature data.

Zeta-potential measurement using the Smoluchowski equation and the slope of the current-time relationship in electroosmotic flow.
TL;DR: This study presents a novel experimental technique to measure the zeta -potential of flat surfaces that combines the Smoluchowski equation with the measured slope of current-time relationship in electroosmotic flow.

Polymer surface with graft chains
TL;DR: A review of surface modification techniques for polymers with graft chains can be found in this paper, focusing on grafting methods as well as the structure and function of grafted surfaces.
Journal ArticleDOI
Extended Electrokinetic Characterization of Flat Solid Surfaces
TL;DR: An experimental setup has been developed and applied for the combined determination of the electrokinetic potential and the surface conductivity of flat surfaces and the results obtained were found to agree well if correct conductivity values for the calculation of the zeta potential based on the streaming potential data are used.

Electrokinetic Measurements Reveal Interfacial Charge at Polymer Films Caused by Simple Electrolyte Ions
TL;DR: In this article, the interfacial charge on spin-coated films of poly(tetrafluoroethylene-co-2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole) (Teflon AF) was studied by streaming potential and streaming current measurements in diluted aqueous solutions of potassium chloride, potassium hydroxide, and hydrochloric acid.

TL;DR: In this article, the classical electrochemistry of the electrical double layer appropriate to materials that operate as electrodes is shown to be a limiting description for non-electrode materials such as clays, inorganic oxides, insoluble salts, latex colloids and biosurfaces.

Flat plate streaming potential investigations: Hydrodynamics and electrokinetic equivalency
TL;DR: In this paper, the development of a flat plate flow system based on (1 × 25 × 75) mm plates is discussed in light of the hydrodynamic requirements and the electrokinetic equivalency between plates and capillaries of the same material is discussed and the small discrepancy is attributed to surface roughness and possible differences in surface chemical composition.

Blood–materials interactions: The minimum interfacial free energy and the optimum polar/apolar ratio hypotheses
TL;DR: Test two popular hypotheses, namely, the minimum interfacial free energy hypothesis and the optimum polar/apolar ratio hypothesis, suggest that platelet adhesion correlates in the opposite direction of whole blood clotting time and partial thromboplastin time, emphasizing the need for a multiparameter approach to blood-materials testing.
