Dr. Zheng's expertise is in materials characterization and electrochemistry, with an emphasis on synthesis and engineering of polymers and hierarchical metal structures. She routinely applies these skills to assess the performance and failures mechanisms of batteries, dielectric coatings and anti-corrosion films often used in consumer products and electronic packaging applications.
Dr. Zheng has extensive experience in various characterization tools including scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), thin film and powder X-ray diffraction techniques (XRD), atomic force microscopy (AFM), ultraviolet — visible (UV-vis) spectroscopy, Fourier-transform infrared spectroscopy(FTIR), Raman spectroscopy, thermogravimetric analysis (TGA), Differential scanning calorimetry (DSC), gas chromatography-mass spectroscopy(GC-MS), nuclear magnetic resonance (NMR), Thermo Mechanical Analysis (TMA), Universal Testing Machine(UTM), electrochemical analysis including galvanostatic, potentiostatic and electrochemical impedance spectroscopy (EIS), Mott-Schotty analysis and Tafel analysis.
By skillfully employing these tools and experimental design techniques, she has successfully solved many complex materials science issues related to corrosion, contamination, polymer and metal fracture, electrical short failure as well as energy conversion efficiency in batteries and fuel cells.
