DESCRIPTION:Experimental advances in the synthesis of colloids and nanopar
 ticles with control over their shape and interactions [1\,2] have opened a
 n avenue for the design of new materials with desired functionalities. To 
 leverage the full potential of this approach\, it is necessary to decipher
  the relation between the particles’ interactions and the ordered struct
 ures that they can form. In this talk\, we will show how to rationally des
 ign a model system to obtain a given target structure\, focusing on icosah
 edral quasicrystals (IQCs). These are materials that are ordered but lack 
 periodicity in any direction of space. In nature\, they have been observed
  in many metallic alloys\, but\, so far\, never in non-metallic or one-com
 ponent systems [3\,4].  We demonstrate that IQCs can be engineered by usin
 g model particles with bonds that mimic the local environments found in th
 e target IQC [5]. We hypothesize that the designed models might be experim
 entally realizable in light of the impressive advances in the design of DN
 A origamis [6] and proteins [7]. If the time allows\, we will also discuss
  the possibility of using a similar approach to assemble axial quasicrysta
 ls (which are aperiodic in two dimensions\, but periodic in the third one)
