title: Tuning the iridescence of chiral nematic cellulose nanocrystals and mesoporous silica films by substrate variation.
abstract: We have discovered that the self-assembly of cellulose nanocrystals (CNCs) into chiral nematic phases varies significantly with the substrate and evaporation rate. These variables allow the reflectance peak of iridescent chiral nematic films of CNCs and mesoporous silica templated from CNCs to be tuned over a wide range of wavelengths.
