In this work, glycerol and hot-pressing treatment were utilized to enhance the waterresistant and mechanical properties of microfibrillated cellulose (MFC) film. Recently, MFC films have been suggested as promising materials for various applications such as flexible electronics, micro-optical devices, and biosensors.

Cellulose aerogels are a potential candidate for heat insulation, but one of their drawbacks is high flammability hindering their applications in practice. This study synthesized cellulose aerogels from microfibrillated cellulose fibers (MFC) extracted from discarded pineapple leaves.

Interaction between xylan and cellulose microfibrils is required to maintain the integrity of secondary cell walls. However, the mechanisms governing their assembly and the effects on cellulose surface polymers are not fully clear. Here, molecular dynamics simulations are used to study xylan adsorption onto hydrated cellulose fibrils.

In this study, we present a facile, one-step method for the manufacturing of all-cellulose, layered membranes containing cellulose nanocrystals (CNC), TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl radical)-mediated oxidized cellulose nanofibers (TO-CNF), or zwitterionic polymer grafted cellulose nanocrystals (CNC-gPCysMA) as functional entities in combination with cellulose fibers and commercial grade microfibrillated cellulose.

In the present study, wrinkled surfaces were discovered on the cell wall thickenings of helical vessels in the lilac style for the first time. The structure of the wrinkles was formed by cellulose microfibrils, with convex ridges composed of crystalline cellulose and concave grooves composed of amorphous cellulose. The cellulose microfibrils were oriented with the helical cell wall thickenings. The wrinkle morphology was due to the aligned crystalline region of the microfibrils.

Cellulose from grasses and cereals makes up much of the potential raw material for biofuel production. It is not clear if cellulose microfibrils from grasses and cereals differ in structure from those of other plants.

The cortical microtubules (CMTs) that line the plasma membrane of interphase plant cells are extensively studied owing to their importance in forming cell walls, and their usefulness as a model system for the study of MT dynamic instability and acentrosomal MT organization. CMTs influence the orientation and structure of cellulose microfibrils in the cell wall by cooperatively forming arrays of varied patterns from parallel to netted.
