From: pH dependence of the chirality of nematic cellulose nanocrystals
POM images of 13 wt% CNC LC in droplets (a–e): (a) pH = 1.5, (b) pH = 2, (c) pH = 3, (d) pH = 5, (e) pH = 10. POM images of 8 wt% CNC LC in droplets (f–j): (f) pH = 1.5, (g) pH = 2, (h) pH = 9, (i) pH = 10, (j) pH=12. Phase diagram of CNC LCs are shown in (k), where letter “N”, “CN”, and “I” represent nematic (black squares), chiral nematic (blue triangles) and isotropic phases (red diamonds) respectively.
