Potential energy diagrams, colloidal

Fig. 17.3. Diagrammatic representation of the origin of the maximum in the potential energy diagram for colloidal particles immersed in a polymer solution.

Use schematic diagrams to describe the influence of electrolyte concentration, type of electrolyte, magnitude of surface electrostatic potential and strength of the Hamaker constant on the interaction energy between two colloidal-sized spherical particles in aqueous solution. What theory did you use to obtain your description Briefly describe the main features of this theory. 

These results indicate that the transition from surface state III to surface state II is thermodynamically favorable. The redox potential of the trapped site coordinated with one carboxyl groups is less negative than the redox potential of the site coordinated with two carboxyl groups simultaneously. On this basis the energy level diagram of the electron trapped sites was proposed (Fig. 6). Such temperature transformations are typical for Pb doped and pure aqueous colloidal solutions. When the temperature is raised to room temperature for Pb ion doped solution, all photogenerated electrons are scavenged by metal ions,...

(b) Energy levels and the harvesting of energy from a photon for an acceptor-donor interface within a photoactive layer of a PV cell. The electron affinity and ionization potential are shown as x and IP, respectively. LUMO and HOMO are the lowest unoccupied molecular orbital and highest occupied molecular orbital, respectively. CB and VB represent the conduction and valence bands, respectively. PC and PAn are photocathode and photoanode, respectively. A schematic of the PV cell design for which the above diagram applies is also shown. (Adapted from Saunders, B.R. et al., A[Pg.479]
