 me étage\, Bât 100\, Campus d'Orsay - 18 Oct 12 14:00
DESCRIPTION:Interplay of anisotropy and interactions in charged colloidal d
 isks \nSara JABBARI-FAROUJI\, LPTMS\n\nCharged plate-like colloidal suspen
 sions such as gibbsite and some clays exhibit interesting and rich phase b
 ehavior including liquid-crystalline and arrested gel-like states. The ani
 sotropic shape of such particles suggests that these materials could form 
 liquid crystalline phases due to the competition between positional and or
 ientational entropy. In some cases\, however\, isotropic-nematic transitio
 n is hindered by formation of a gel-like viscoelastic phase. The question 
 that arises is how the electrostatic interactions influence the liquid cry
 stal formation. Motivated by these experimental findings\, we have investi
 gated the structure and dynamics of charged disks by means of Monte-Carlo 
 simulations. In this talk\, I will clarify the the role of anisotropic nat
 ure of screened electrostatic interactions on the formation of liquid-crys
 talline phases and arrested states. Finally\, I will compare the results o
 f our simulations with experiments.
