Hanfeng Zhou is a postdoctoral researcher in the Department of Chemistry at University of Hong Kong. Her research focuses on the confinement and dynamics of ions and molecules in porous materials with ordered porosity. It covers two areas: the ion-sieving effect in porous carbon materials with subnanopores, and the activities of bioactive ions and molecules in porous conductive metal-organic frameworks, with related applications in ionic devices (including ionic diodes, ionic transistors and ionic memristors) and ionic drug delivery.
