C-ing cellulose in a new light: The self-assembly of nanocrystalline cellulose (NCC) with tetraalkoxysilane produces a chiral nematic NCC–silica composite material, which upon carbonization, and then etching of the silica with dilute base solution produces a novel high surface area chiral nematic mesoporous carbon (see picture).
