This article summarizes our work with (1) reaction mechanisms at hydrocarbon-water interfaces, (2) the use of emulsifying agents in synthetically useful interfacial systems, (3) the conformations of bolaform electrolytes at air-water interfaces, (4) the analysis of reaction kinetics at micellar surfaces, (5) the rotamer population at a micelle interface, (6) mechanisms of fast proton transfers at a micelle interface, (7) the properties of organic and enzymatic reactions occurring inside water pools, (8) the design of a polymeric reducing agent and (9) the pyrochromatography of structurally related steroids using hot quartz and platinum surfaces in the absence of O2. © 1979, Walter de Gruyter.
