Relatively high electroosmotic pressures are produced when a dissociable species such as water is present in the system 7-alumina-2-propanol and potentials in the kilovolt region are applied. Pressures above 3 atm were observed in this study. A theoretical expression, based on Onsager's treatment of the dissociation field effect, is derived for the electroosmotic pressure as a function of the applied potential. The equation agrees qualitatively with the measured data.
When ultrahigh molecular weight elastomers are dissolved in hydrocarbon liquids the resulting solutions become highly cohesive under tensile stress. The effect increases with increasing molecular weight and concentration of the polymer, decreasing temperature, and increasing viscosity of the liquid. The benefits derived from using ultrahigh molecular weight elastomers in oil spill response and removal activities are: increased resistance to spreading, automatic separation of oil and water at the skimmer, and increased capacity of skimmer devices. In general, these benefits translate into reduced labor, transportation, storage or disposal costs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
