2. Surface zeta potential measurements
3. Nanoscale characterization of material surface properties such as work function, hydrophobicity, chemical mapping, and roughness using hybrid AFM
4. Filtration membrane module design and fabrication
5. Surface deposition/adsorption kinetics and desorption kinetics and correlation with interaction energies
6. Microwave catalysis and microwave reactor design
7. Photocatalysis (e.g., bandgap, light penetration, and photoelectrochemical)
8. Electrochemical measurement (e.g., CV, EIS, and LSV)
9. Nanocrystal synthesis
10. DFT calculation for surface energies, adsorption energies, pollutant degradation pathways
11. COMSOL modeling for mass/heat and electric mass transfer for various applications such as electrochemical systems, hydrogen fuel cell and water electrolyzer (e.g., Fuel Cell & Electrolyzer Module. We can cover the following modeling/simulation:
