Aerosol-assisted Approaches to Fabricating Advanced Membranes
The aerosol-assisted approach utilizes the dynamics of droplet evaporation, dispersion, and deposition for membrane building block delivery, which is fundamentally different from dip coating and other liquid-based methods. It is much faster, more efficient, and easily scalable. With this approach, the membranes will be fabricated with much shorter time (down to minutes) and fewer materials (minimization of material waste), and can have similar, if not better, permeability and selectivity properties compared to those obtained via current liquid-based approaches. |

Magnetic Confinement for Water Treatment This project explores novel magnetic confinement of nanomaterials for filtration or catalysis in advanced water treatment. Our studies show that magnetic nanomaterials can be effectively immobilized and assembled in various magnetic fields, which thus opens up opportunities to build unprecedented yet superior water treatment systems.
