Cellulose Nanocrystals: Mind the Microgap in Iridescent Cellulose Nanocrystal Films (Adv. Mater. 2/2017)

Cellulose nanocrystals are isolated from plant cellulose structures, e.g., cotton. In article 1603560, M. H. Godinho and co-workers describe a tunable photonic material produced from these cellulose nanocrystals iridescent films, which reflects both right- and left-handed circularly polarized light, taking advantage of the gaps existing along the cellulose nanocrystals films that are filled with a nematic liquid crystal. Recently published in one of the most prestigious journals in the field of materials, Advanced Materials (Recentemente publicado numa das mais prestigiadas revistas da área dos materiais, a Advanced Materials) (+)
