The papers presented in this session on dispersion, rheology and mixing cover a broad spectrum of topics ranging from instrumentation for better characterization, to process development for improved stabilization, selective flocculation and dense packing, to modeling of colloidal dispersions. There are also some, but limited, efforts to understand the mechanisms involved in these processes. Importantly, there is a clear trend to adapt, modify and develop techniques and instrumentations for even the difficult to characterize, highly concentrated dispersions. While the reported works deal with different systems, they all address a common problem : control of interfacial properties via chemical or physical means to achieve the desired stability or flocculation of suspensions and in some cases selectively.
