DESCRIPTION:Speakers: Joao Cabral (Dept. of Chemical Engineering\, Imperia
 l College London\, UK)\nMicrofluidics provides an exceptional platform for
  the generation of polymer solution droplets and their subsequent manipula
 tion. We describe the formation of polymeric particles and capsules induce
 d by solvent extraction\, with broad applications in the pharmaceutical an
 d consumer good industries. A microflow approach to perform small angle ne
 utron scattering (SANS) and phase mapping of multicomponent liquid mixture
 s is first described\, and the development of reconfigurable microfluidic-
 SANS. By contrast with conventional techniques\, our approach continually 
 varies solution composition during SANS acquisition\, enabling global fits
  of large\, constrained datasets\, leading to unprecedented robustness and
  precision. After establishing the phase diagram of model polymer and coll
 oidal solutions\, we obtain a capsule morphology diagram\, attaining inter
 nal morphologies encompassing nucleated and bicontinuous microstructures\,
  as well as isotropic and non-isotropic external shapes. Equipped with thi
 s knowledge\, we design and fabricate composite capsules and particles wit
 h prescribed structure and pulsed release profile\, with time scales tunab
 le from seconds to hours.\n\nhttps://lindico453.srv.lu.se/event/67/contrib
