Understanding these structural changes in terms of the strength and range of depletion attractions is being explored. Studying the effects of particle-particle attractions induced by the addition of non-adsorbing polymer are imperative in the development of non-empirical theoretical predictions that help develop the understanding of phase equilbria as systems approach non-ergodic transitions. Previous USAXS studies have helped in the development of these models and we wish to extend our studies to include a wider range of experimenatal parameters. Previous experiments conducted using the side-bounce USAXS technique that did not require the need for raw data desmearing proved to be very insightful. Additional data collection in this mode of operation would be very helpful. equipment+required: Side Bounce USAXS (if possible?)
