Microswimmer, complex fluids, rheology
I mainly focus on the self-assembly of particles and the rheology of complex fluids. The autonomous assembly and operation of micro and nanomachines that perform useful tasks beyond the molecular scale have been a long-standing vision of nanotechnology. To overcome friction at low Reynold’s number, micro/nano machines needs to continuously adsorb energy from the environment and convert it into mechanical motion. We propose a modular approach to microswimming, that is, the self-assembly of both active and inactive components leads to the self-propulsion. We further develop a scale invariant platform by magnetic encoding for programmable self-assembly.
The structure and rheological properties of complex fluids, such as colloidal suspensions and polymer composites, are closely related with their processing and application. We propose a strategy to control the solidification of concentrated colloidal suspensions under extension and compression. We also related the structures of polymer composites under shear with the normal stresses to solve the instability problem of polymer composites under extrusion. I have published 30 papers, including PRL, PNAS, Sci. Adv., ACS Nano.
