Professor Julia Yeomans
Active materials such as bacteria, molecular motors and self-propelled colloids, are Nature’s engines. They continuously transform chemical energy from their environment to mechanical work. Because they are tiny, the engines operate in a very different environment to manmade machines, where they have to contend with crowding, strong fluctuations and high viscosities.
Dense active matter shows mesoscale turbulence, the emergence of chaotic flow structures characterised by high vorticity and topological defects. I shall discuss how dense active matter might be harnessed to provide energy and show that, surprisingly, topological defects, which are important in the physics of liquid crystals, may play a role in
The talk is open to anyone with an interest and will start at 19:00 with refreshments served beforehand.
Registration via Eventbrite is not essential, but helps us judge capacity and the refreshments required.
