Abstract

Pierre de Gennes received the Nobel prize in Physics in 1991 for ‘discovering that methods developed for studying order phenomena in simple systems can be generalised to more complex forms of matter, in particular to liquid crystals and polymers’. Liquid crystals, polymers, foams, emulsions and suspensions are common examples of a class of matter called ‘soft materials’ – materials characterised by structural complexity and mechanical flexibility. In this talk, we will together try to decipher the intriguing flow and deformation properties of some very common soft materials that we encounter everyday - materials categorised  as colloidal suspensions (clay, smoke, fog, ink and milk), emulsions (mayonnaise, lotions and creams), liquid foams, pastes (tomato ketchup and toothpaste), granular media (a bag of rice or sand) and polymers.
