TI  - Dynamic arrest of nematic liquid-crystal colloid networks.
PG  - 042505
AB  - We report interesting self-assembly structures of nematic liquid-crystal colloid 
      (NLCC) networks, which are arrested during cooling from the isotropic temperature 
      to room temperature. The NLCC is composed of sterically stabilized colloidal 
      particles and a nematic liquid crystal (NLC) with nematic-isotropic transition 
      temperature (T_NI) that is much higher than those of previously studied 
      4-Cyano-4'-pentylbiphenyl and N-(4-Methoxybenzylidene)-4-butylaniline. We find 
      that the structure of NLCCs depends on T(NI), cooling rates, and boundary 
      conditions, varying from cellular network to hierarchical fern structures in 
      different length scales. Our time-lapse study shows that the transition from the 
      cellular network to the fern structure directly corresponds to the transition 
      from a spinodal demixing to a nucleation-and-growth mechanism.
