The micro/nano-scale interfacial instabilities of thin-micro/nano films engendered by the externally applied Electric (electro-hydrodynamics: EHD) and Electro-Magnetic (electro-magneto-hydrodynamics: EMHD) fields will be investigated. Previous studies suggest that external field induced (EHD or EMHD) flows and related instabilities can be of importance for transporting, patterning, mixing and pumping liquids inside the micro/nano scale devices.
We plan to investigate the dynamics and morphology of thin films composed of a pair of liquid electrolytes/ polymer films/ liquid crystals/ polymer gels or composites of any two of these materials. The major aims of this study to explore the conditions at which the control of instability can lead to ordered micro/nano patterns, guide micro-channel flows for transport, enhance the heat and mass transfer, mixing, emulsification, etc.
The scientific understanding and the related applications can be of importance especially in the context of micro/nano fluidics in lab-on-a-chip, microreactors, microelectronic, and drug-delivery devices among others.
