Soft Matter & Complex Fluid Lab

The core of our research lies in studying the formation and evolution of material microstructure and its relationship to macroscopic rheological properties. We employ this understanding to create materials with the desired microstructure and functional properties.

Research

We study how interfacial forces impact the dynamics of complex fluids such as suspensions, emulsions, foams, micro-emulsions, polymers and glasses. These are already crucial for industrial processes and products due to their peculiar rheology and flow characteristics. But we are now in an era where industries must maneuver through quick transitions in technologies under restricting resources, laying stress on novel materials that tailor to a purpose with a specific property.

 

Through a combination of experiments and theoretical models we create the desired characteristics by using fundamentals of solid mechanics, hydrodynamics, surface phenomena and statistical thermodynamics. We rely on experimental techniques of imaging, diffraction and scattering, rheometry and use computational techniques such as molecular dynamics and finite element methods.

Crystallization and Rheology of Mono- and Diglycerides and Their Role in Stabilization of Emulsion Droplets in Model Topical Ointments

The crystallization behavior of commercial mono- and diglycerides (MDG) in paraffin oil is studied to develop an in-depth understanding of the polymorphic transitions useful for the physical stability of petroleum oil-based topical emulsions. Optical microscopy and differential scanning calorimetry measurements showed the formation of plate-like and spherulite crystals at high and low temperatures, in sequence, while cooling a solution of MDG dissolved in oil.
