CFN Research Activities

Complex fluids and soft materials are ubiquitous, with applications ranging from the everyday (e.g., shampoos, cosmetics, lotions, paints, and foods) to high-technology products for biomedical and energy applications (e.g., pharmaceutical formulations, wound dressings, advanced coatings, biofuels, and flow batteries). The overarching goal of our program is to connect the structure of complex fluids and soft materials to their phase behavior, transport characteristics, and flow behavior. Our group distinguishes itself by combining structural characterization techniques that cover a wide range of length scales, such as ultra-small-angle scattering (USAS), with rheological and transport measurements.  Some highlights of our program include creation of synthetic biomaterials that mimic microstructures found in natural tissues; development of gels with improved oxygen delivery for wound healing;  discovery of “re-entrant behavior” in disk-shaped dispersions, whereby the behavior of dispersions at high volume fractions can be changed from a gel to a liquid; and development of techniques to produce large nanoparticle clusters, relevant to applications in printing, biosensors, and drug delivery.
