Our aim is to gain new insights into nano/microscale mechanisms underlying thermofluidic and interfacial phenomena and to use this knowledge to design nanoengineered solutions which enhance the macroscale performance of a variety of industrial systems. Our current work focuses on enhancing the efficiency of thermal energy and stretchable liquid electronic systems and safety of transportation systems and chemical/biological protective equipment.
