Ph.D. student, Guangyu Zhu, demonstrated his research about the use of high-pressure RO/NF membranes to remove PFAS with high efficiency. He also presented his thorough research on a novel induction-heating-assisted membrane distillation to Dr. Yang. This technology utilizes electromagnetic induction energy to locally heat membrane/liquid interface to power salty water vaporization and transportation in direct-contact membrane distillation (DCMD) processes. Electromagnetic induction enables contactless, fast, efficient and accurately controlled heating, It could exceed over 90% efficiency and heat losses to the ambient are reduced compared to convention electrical heating
Furthermore, Dr. Yang was introduced to an innovative algal water treatment process devised by our Ph.D. student, Lili Li. This method employs positively charged functionalized magnetic particles to adsorb algae cells, facilitating the direct elimination of particulate matter without the requirement for supplementary chemical agents. Lili's presentation underscored the crucial role of this process in the immediate management of cyanobacterial blooms and the subsequent ecological rejuvenation of water ecosystems. Dr. Yang was deeply impressed by this presentation and pointed out that this technology could also be used for the recovery and subsequent resource utilization of energy microalgae
Ph.D. student, Jiahe Zhang, is advancing the field of environmental science by utilizing Atomic Force Microscopy (AFM) characterization techniques to study the absorption of Per- and Polyfluoroalkyl Substances (PFAS) on membranes. His research primarily focuses on the effectiveness of AFM-IR and Kelvin Probe Force Microscopy (KPFM) in detecting trace amounts of PFAS on membrane surfaces
