Areas of Research Interests/ Research Projects
Dr. Sun’s research interests include chemistry and chemical engineering in the nuclear fuel cycle and coordination chemistry of lanthanides and actinides.
Chemistry and chemical engineering in the nuclear fuel cycle
(1) Process development and optimization for the extraction separation of radionuclides from high-level liquid waste.
(2) Aggregation behavior in the extraction separation of radionuclides using surface-active extractants, primarily associated with the formation of microemulsions.
Coordination chemistry of lanthanides and actinides
(1) Development of new conceptual frameworks for chemical bonding of f-electron by the study on the molecular geometry and electronic structure of lanthanide and actinide complexes using molecular spectroscopy techniques (such as X-ray absorption and emission spectroscopy) in combination with density functional theory (DFT) calculations.
(2) Unraveling the relationship between the extraction ability of extractants and the bond covalency in the complexes of lanthanides and actinides by crystallization, ligand K-edge X-ray absorption spectroscopy (XAS), and density functional theory (DFT) calculations.
