Título: Non-equilibrium dynamics of confined lipid membranes: a prototype for
complex biological interfaces

Apresentador: Olivier Pierre-Louis - Université de Lyon (pesquisador
visitante especial CSF-CNPq na UFF)

Resumo: Lipid membranes are ubiquitous in biological systems. They play a
central role at complex biological interfaces. They have been observed not only
as cell walls, but also as protective coatings in articular joints, in the
lungs, the eye, and in the skin. Due to molecular crowding or to the complex
architecture of living matter, these membranes are usually subject to strong
confinement conditions. Using hydrodynamic models we have studied theoretically
the influence of confinement on membrane dynamics. Depending on the conditions,
the nonlinear dynamics of the membranes produce frozen patches (which exhibit
an order-disorder transition), or coarsening dynamics. The role of noise is
also discussed.
