Scientific Achievement
Derived expressions for peak intensity in 2D-NMR experiments from linear free energy vs. penetration model and Fokker-Planck equation. Tennakoon et al. Nat. Catal. (2020), Chen and Peters, AIP Adv. (2022), Chen et al. J. Phys. Chem. C. (2022)
Significance and impact
Enables quantitative estimates of polymer reptation diffusivity and polymer-wall interactions in silica nanopores. The results should help us understand how pore diameter, pore length, wall-functionality, and polymer chemistry impact adsorption and mobility in core-shell catalysts.
