摘要：
The chiral environment of enantiomerically pure d-alanine solutions is observed to disrupt and modify the entropy-driven assembly of cellulose nanocrystals (CNCs) into a chiral nematic mesophase. The effect is specific to d-alanine and cannot be attributed to the adsorption of alanine molecules (neither d- nor l-alanine) onto the CNC particles.
