During mercerization, cellulose undergoes a conversion from form I to form II which involves change of the direction of every other cellulose chain but a clear understanding of how this change happens is lacking. Here, the authors use neutron diffrac

A N-acetylated chitosan hydrogel was investigated for ocular applications. One of the drawbacks in the original hydrogel protocol, poor moldability, was circumvented by optimizing the addition of the acetylating agent, acetic acid anhydride (Ac2O), a
