โœฆ Synopsis

This paper describes an effort to measure and model changes in the adhesion of micron-scale particles to substrates in systems in which chemical reactions are occurring. Contact interactions between polystyrene latex spheres and silicon substrates (with surface oxide) immersed in aqueous KNO 3 solutions were studied. Two important results were obtained. First, it was shown that the AFM can be employed to monitor, in situ, changes in adhesive interactions induced by surface chemical reactions in this system. Second, the morphology of the interacting surfaces plays a controlling role in particle adhesion. In particular, for this system, changes in roughness of the substrate changed the interaction force by nearly 90%.

## Abstract The effects of mass transport resistances on twoโ€substrate immobilized enzyme systems are investigated theoretically. It is shown that the effects of mass transport resistances on the overall reaction rate are related mainly to the transport of the limiting substrate. In the absence of

Indomethacin (IMC)/polyvinylpyrrolidone systems were prepared under different technological conditions, using co-evaporation, kneading, traditional, and ultrasound (US) compaction. The materials thus obtained were milled and sieved and the powders were analyzed by using scanning electron microscopy
