Liquid Gold Anna Curran Department of Mathematics A lattice of bubbles inside a ring that has been dipped in soapy water. The bubbles hold their shape because of molecules in the dish soap called surfactants, which stabilise the interface. Surfactants are all around us - for example, they allow soap to break down dirt and bacteria, and they are given to premature babies to help them inflate their lungs. Conversely, they threaten the efficacy of various industrial applications such as self-cleaning surfaces and laptop cooling systems. My research focuses on mathematically modelling the effect of these molecules at a f luid interface, in order to gain a greater understanding of how to control their behaviour in these applications.
