DESCRIPTION:Speaker: Dr. Carla Fernandez Rico\nhosted by Maria Ibáñez\nAb
 stract: Phase separation is a fascinating physical process that is not onl
 y responsible for the internal organization of living cells but also a pro
 mising tool for structuring materials. The central challenge in making mes
 o-structured materials via phase separation is the lack of structural cont
 rol at length scales beyond the macromolecular scale. In this talk\, I wil
 l introduce Elastic MicroPhase Separation (EMPS) as a route to create high
 ly correlated and bi-continuous structures in the scale of hundreds of nan
 ometers. The essential idea of our approach is simple\; we counter the the
 rmodynamic forces that drive phase separation with elastic stresses in the
  host matrix. In this way\, we can tune the size and morphology of the str
 uctures by changing the mechanical properties of the matrix.  Analysis of
  the microstructure\, phase equilibria\, and kinetics suggests that these 
 systems emerge through a unique thermodynamic pathway\, featuring aspects 
 of both nucleation and growth and spinodal decomposition. We demonstrate t
 he potential our approach by toughening polymeric materials\, and making b
 i-continuous structures with controlled structural and anisotropic gradien
 ts.
