During AMS15 gathering scientists working on membranes in the Aseanian area, I was selected as one of the Keynote speakers, and chose to present our recently published studies on the fabrication of vapor-induced phase separation membranes for direct contact membrane distillation applications. My goal was to convince the audience that VIPS membranes can compete with/outperform both wet-immersion and electrospinning membranes for such an application. The slides I presented are presented below.
I was invited to give a talk at the 2025 International Membrane Conference in Taiwan (a joint meeting with the International Symposium on AI-Driven Carbon-Neutral Technologies and Circular Bioeconomy). In this presentation, I shared our recent progress on the development of PVDF-based nanocomposite membranes, prepared via either the VIPS or LIPS process, and designed for DCMD or PMR applications. The talk focused on both seawater desalination and broader water treatment challenges, including the removal of PFOA and the remediation of antibiotics.
During the Annual Meeting of the Taiwan Polymer Society (2025中華民國高分子學會年會) held in Taichung on January 15th and 16th, I had the opportunity to present our progress on the development of antifouling porous membranes using greener solvents. Different from the results obtained with dimethyl sulfoxide and triethyl phosphate presented during the previous meeting, I solely focussed on introducing the membrane systems prepared using γ-Valerolactone as a solvent. I laid the focus on membranes prepared in one step by phase inversion of a blend, and on membranes prepared by spray-coating. While it is challenging to obtain homogeneous solutions containing both poly(vinylidene fluoride) and an antifouling amphiphilic copolymer using γ-Valerolactone, it is doable and homogeneous porous membranes efficiently mitigating fouling can be prepared. Otherwise, spray-coating is very efficient for top-to-bottom modification of the membranes.
I presented the recent results of our team on the utilization of nanomaterials to improve the properties of porous membranes in water treatment-related applications at the international workshop on membranes at Kobe university (iWMK2024) held on November 14 and 15, 2024. In particular, I discussed the systems we used in the treatment of oil and water, the degradation of antibiotics, and in desalination. As some of these results are still unpublished, only a sample of the presentation is available below. The most recent results concerning photocatalytic membrane reactors and desalination will be shared later.
In the frame of the International Conference on the Science and Applications of Nanotubes and Low Dimensional Materials, I presented our work on the utilization of nanomaterials for the improvement of porous membrane performances. I specifically focussed on the use of graphene oxide and of metal organic framework.
I was invited to provide a lecture to graduate students at the Department of Chemical Engineering of the National Taiwan University of Science and Technology.
During the talk, I try to introduce various methods to design antifouling membranes, and to discuss some important process parameters to adjust to optimize the tradeoff between stability of the design and antifouling properties.
During the Annual Meeting of the Taiwan Polymer Society (2024中華民國高分子學會年會) held in Tainan on January 24th and 25th, I had the opportunity to present our ongoing research on the development of antifouling porous membranes using greener solvents than the ones we used to employ. Hence I presented some results obtained with dimethyl sulfoxide, triethyl phosphate, γ-Valerolactone, trying to emphasize also the effect of the solvent on the membrane structure. The presentation is available below.
I had the opprotunity to deliver a Keynote lecture during ICOM 2023 on the formation and application of PVDF VIPS membrane in direct contact membrane distillation. The presentation also showcased the steps taken in order to optimize the membrane performances, via the formation process and formulation parameters.
During this conference, Dr Maggay presented her work on the development of skin-free and macrovoids-free polysulfone membranes. Interestingly, the membranes that she prepared have similar permeabilities to those measured with more conventional membranes (with macrovoids) but much better mechanical properties.
During this conference, I presented our recent studies on the development of functional membranes for killing bacteria during their permeation, degrading antibiotics during filtration, and selectively removing leukocytes from whole blood.
During this talk at the International Symposium on Novel and Sustainable Technology, I summarized our recent studies on the applications of anti-biofouling membranes in the biomedical fields.
A work on the separation of drug enantiomers, presented at the 16th International Conference on Inorganic Membranes (ICIM16) by Dr. Irish Maggay, postdoctoral researcher in our lab (more about her here), in Taipei (Taiwan).
A summary of our recent activity on the design of leukodepletion filters, presented online at the International Conference of Innovative Application Technology, organized by the College of Engineering of CYCU.
A summary of our works on the application of anti-biofouling membranes as wound dressing materials presented at the International Membrane Science and Technology 2020, in Sydney, Australia.
During the 2019 EMN Meeting on Polymer in Hawaii (USA) we presented a series of works showcasing membranes able to break emulsions solely under the action of gravity. These membranes are all imparted with superwettability.
During iWMK 2019 in Kobe (Japan), we presented our results concerning the essential molecular design parameters essential to consider in order to optimize the performances of antifouling membranes. We shared data obtained with both PEGylated and zwitterionic copolymers.
We attended the annual conference of the North American Membrane Society in 2019, NAMS 2019, held in Pittsburg, PA (USA). Druing the talk, we placed the emphasis on the design similarities betwen biofouling-resistant membranes and wound healing materials.
