Laser diffraction and dynamic light scattering enable the identification of an optimal particle size distribution for dairy emulsions to support the cost-effective manufacture of high quality products.
In this article we take an introductory look at work carried out by TU Clausthal to develop an improved understanding of the mechanisms of enhanced oil recovery (EOR) by polymer flooding, and the relevance of fluid rheology. Example data illustrates the insight that rheology provides and its application in optimizing fluid performance.
In particular, this article demonstrates the correlation between molecular changes (Raman Spectroscopy) and microstructural evolution of rheological properties (DLS, DLS-optical microrheology) for the first time for surfactant-based wormlike micellar system. Whereby, Raman Spectroscopy provides information about the molecular structure and DLS-microrheology characterizes viscoelastic properties, the combination of data delivered allows for a deeper understanding of the molecular changes underlying the viscoelastic ones. The study illustrates the utility of the combined DLS, DLS-optical microrheology and Raman Spectroscopy in providing new molecular structural insights into the self-assembly process in complex fluids.
