Based on the separation chemistry of rare earth and chemical fabrications, our research is focused on the control of the structure and microstructure, particle size and its distribution, morphology, and surface and interface of rare earth functional materials, so as to modify and enhance the behaviors. At present, our topics of research are as follows:
(1) Optimized design and automation of rare earth separation processes;
(2) Self-assembly of the rare earth molecular materials;
(3) Fabrication and characterization of the nanosized rare earth functional materials.
