CME Undergraduate Marks a Breakthrough in Membrane Technology by Publishing in SCI Tier-1 Journal

2021-07-07

The Research Center congratulates undergraduate student Jiang Xinnian from XMUM School of Energy and Chemical Engineering for publishing a research paper in SCI Tier-1 Journal as the first author.  

Titled “Understanding the role of substrates on thin film composite membranes: a green solvent approach with TamiSolve® NxG”, the article was published in the top journal Journal of Membrane Science (latest impact factor of 8.742).

This research was carried out under the supervision of Assoc. Prof. Dr. Yong Wai Fen, the corresponding author of the article. This is a collaborative project with researchers from National University of Singapore and Nanjing Tech University, China.  

The authors reported an innovative approach using TamiSolve® NxG as a green solvent for the preparation of polyethersulfone (PESU) thin film composite (TFC) membrane via nonsolvent induced phase separation. The feasibility study was evaluated in terms of Hansen solubility parameters, ternary phase diagram, physical properties and toxicity. The impact of substrates on the separation performance of TFC membranes were investigated from morphology, thickness, porosity, pore size, hydrophilicity and pure water permeability (PWP). The substrates with different pore sizes were prepared while the TFC membranes demonstrated a promising separation performance with PWP and NaCl rejections of 0.64- 3.54 LMH/bar and 91.4%- 94.1%, respectively. It was found that the pore size and hydrophilicity of the substrates play key roles in determining the surface morphology of TFC, which will influence PWP. The fundamentals gained from this study may facilitate the development of TFC membranes using green solvents towards a sustainable membrane fabrication process.

Jiang: “I deeply appreciate this opportunity to work with Dr. Yong. It was Dr. Yong who helped me overcome one after another research difficulties and guided me on how to become a real researcher in terms of format, conceptualization, methodology, experiment and paper writing. Besides, I respect her rigorous attitude towards research from the bottom of my heart. After going through the research process, I realized the importance of teamwork in finishing a research project. Last but not least, I want to thank myself for my persistence in completing the research project and my passion in membrane technology. In the future, I wish to become an outstanding researcher like Dr. Yong.”
