On March 31st, 2023, our group attended the National Polymer Characterization conference held in Shenzhen. Prof. Zhang gave an invited talk titled "Solid-state NMR methods for structural characterization of multiphae polymers". Yuling gave an oral talk titled "tunable topology and viscoelasticity of polymer network via anion-adaptive metal-organic macrocycles".  Zhiwei prepared a poster titled "An efficient solid-state NMR method for collecting 13C-1H HETCOR spectra of multiphase polymers". Jingchao also gave a poster titled "low-field NMR studies on the structure and dynamics of polyurethane crosslinked by non-covalent bonds"
