SUMMARY:Avenues to Active Shape Control in Nematic Solid Sheets - Modes\, 
 CD (Rockefeller University)

CONTACT:Mustapha Amrani
DESCRIPTION:Much recent progress has been made in the study of nematic sol
 ids\, both glassy and elastomeric in connection with these materials' rema
 rkable coupling of the nematic texture and liquid crystalline properties t
 o bulk elasticity and deformations. This talk will present a survey of the
  mechanisms and machineries that have been recently developed to allow for
  active control of many aspects of the shape of a thin sheet or shell of n
 ematic solid: extrinsic bending\, the blueprinting of intrinsic curvature 
 and shape\, switchable pores\, and more. These examples\, in addition to p
 roviding a rich tool box for potential device design\, will also elucidate
  the connection between the topology of the nematic director field and the
  geometry of elastic deformations in this model system.\n
