Radical modelling innovation
Wetsus and University of Twente scientists managed to fabricate and model a photocatalytic membrane for water purification applications. The filter, made with a top layer of titanium dioxide, could destroy model compounds through UV-induced radical formation.
This radical filtration synergy is still underused, despite its promising features. With their experimental setup, they managed to discolor nearly 70% of the model compound, methylene blue, through a similar mechanism as what would affect microbes. The scientists further developed a theoretical model to explore the concept and accuracy of studying.
