In this episode, Hakim and cohost Rhea Verbeke talk with Prof. Ranil Wickramasinghe, a membrane expert who takes us from blood oxygenators to advanced water and biotech applications. We explore why polymer membranes still lead, how catalytic ceramic membranes turn vegetable oil into linoleic acid for green products, and the real-world hurdles like fouling and carbon pricing. Curious how membranes can react, separate, and still clog like a throat mid-sentence? Tune in. 🌱🧪
