Come join us for the first Nano-Science Center Seminar of the semester! Friday the 13th of September at 15:00 in aud. 5 Associate Professor Amin Doostmohammadi will give a talk called "Engines of Life: From Dancing Defects to Autonomous Shells of Active Material".At 15.45 there will be free beers and snacks in DS03
Looking forward to see you!
All Science students are welcome.
"The spontaneous emergence of collective flows is a generic property of active fluids and often leads to chaotic flow patterns characterized by swirls, jets, and topological disclinations in their orientation field. I will first discuss two examples of these collective features helping us understand biological processes: (i) to explain the tortoise & hare story in bacterial competition: how motility of Pseudomonas aeruginosa bacteria leads to a slower invasion of bacteria colonies, which are individually faster, and (ii) how self-propelled defects lead to finding an unanticipated mechanism for cell death.
I will then discuss various strategies to tame, otherwise chaotic, active flows, showing how hydrodynamic screening of active flows can act as a robust way of controlling and guiding active particles into dynamically ordered coherent structures. I will also explain how combining hydrodynamics with topological constraints can lead to further control of exotic morphologies of active shells."
