full_question: A computation by Sear and Warren showed that this structure has a negative contribution to tension on protein and salt solution interface. The maximum capacitance occurs when carbon electrode pore size equals the ion size in capacitors which rely on this structure. The charge density at these structures is proportional to the hyperbolic sine of e z times the potential times beta in the Grahame equation. The diffuse section of this structure usually begins at the outer Helmholtz plane. The lack of this structure at a protein's isoelectric point is the reason that proteins at that point coagulate so easily. These structures exist in equilibrium of attractive van der Waals forces and repulsive electric force in the DLVO theory of colloids and the potential at their slipping planes is the zeta potential. For 10 points, Gouy-Chapman theory describes what electrical structure in which a surface charge attracts a second level of oppositely charged ions?

raw_answer: electrical double layer [or diffuse layer; or answers that mention the words "interfacial," "Helmholtz," "Stern," or "Gouy-Chapman," as long as the words double layer or diffuse layer are given]
