DESCRIPTION:Kathleen Stebe\nUniversity of Pennsylvania\nParticles at fluid 
 interfaces can form highly ordered structures\nat fluid interfaces spontan
 eously by capillarity. The understanding\nof these interactions for spheri
 cal particles is well developed and\nwidely exploited to make 2-D and 3-D 
 ordered materials.\nAnisotropically shaped particles have far greater degr
 ees of\nfreedom\, and can orient\, align\, and assemble into complex\nstru
 ctures and networks that depend subtly on the particle shape\nand the shap
 e of the interface which hosts the particles. In this\ntalk\, progress in 
 developing a quantitative understanding of pair\ninteractions between part
 icles is described. Experiments on a\nvariety of particle shapes are prese
 nted to illustrate a range of\npossibilities including assembly of particl
 es with complex features\nin registry\, docking sites\, and the molding of
  particle aggregate\nstructures by using the background shape of the inter
 face to force\nnew equilibrium alignments. Open issues associated with the
 \nstructure and mechanical properties of aggregates\, and their\ndependenc
 e on particle geometry and near-field particle\ninteractions are described
 . These issues ultimately determine the\nmechanical response of particle-l
 aden interfaces\, important in\nparticle stabilized (Pickering) emulsions 
 and tailored\ncolloidosomes.\n
