- Provided equations demonstrating leach behaviors of additives from MPs with different shapes into surface water based on Homogeneous Surface Diffusion Model.
- Obtained diffusion coefficients of bisphenol A and 4-tert-butylphenol releasing from epoxy MPs.
- Simulated and compared releasing processes of typical additives from MPs, analyzed the influence of plastic material, chemicals, temperature, and particle properties.
- Tracked and analyzed the latest development of federal and international nanotechnology regulations; created and published relevant summaries, briefs, and explainers of scientific policies on Duke SciPol.org.

- Explored direct photodegradation and indirect photocatalysis with TiO2/Ag and TiO2/Pd of PBBs.
- Predicted the debrominated pathways of PBB and investigated relevant mechanisms corroborated by analysis of degradation products via GC-MS with quantum chemical calculations via Gaussian 16.
- Elucidated innovatively the impact of solvents and the mechanism of oxygen inhibition.
- Synthesized structure-directing agents modified metal-organic framework MIL-53(Al)-1 that remove 99.7% of trace levels of TCS in 10 minutes.
- Explored in-site adoption-degradation of TCS by immobilizing laccase on MIL-53 (Al)-1 via electrospinning.
