This episode of #SURFICEvideoseries introduces our early-stage researchers (ESRs) in Technische Universität Darmstadt, Germany, supervised by Prof. Ilia Roisman. ESR3 (Mingyue Ding) investigates the solidification of supercooled water droplets after impact onto anti-icing substrates and ESR4 (Ali Raza Shaikh) explores the dynamics of ice detachment from complex substrates.
