 Obiettivo del progetto (Objective)

'Dynamic Light Scattering is a widespread technique for measuring fluid properties in soft matter. It is used to investigate complex fluids, colloids, proteins, nano-particles, but also samples of bio-physical and medical interest. The advent of pixilated sensors like CCD cameras and fast computers allowed the design of different imaging techniques aimed at providing the same quantitative information. Dynamic Near Field Imaging (DyNeFI) is a family of novel optical techniques of this kind. Different variants of this new approach have been successfully designed and used for very refined measurements, nevertheless the soft matter community is not aware of this intriguing possibility. The proposed project aims at: increasing the measuring capabilities of DyNeFI by the integration of new measuring concepts, applying it to samples coming from different research areas thus providing new science and starting developing instruments which can be commercialized in a next future. Essentially the project can be divided into three modules: A) Investigation of the dynamics of the transition between capillary waves and non equilibrium fluctuations in a critical binary mixture undergoing phase transition in order to get deeper insight of the dissolution of an interface between two fluid phases and also provide a tool to measure the effective surface tension B) Application of the technique to micro-rheological measurements, in order to compare the Dy-NeFI technique with other tools for measuring the viscoelastic properties of complex fluids C) Extension of the technique to fast dynamics, through Micro Mirror Device concept, in order to overcome the major disadvantage of the technique, which is the limited ability to investigate fast dynamics'
