Helicoidal self-ordering of cellulose microfibrils in aqueous suspension.
TLDR
An in vitro system that attracts by its simplicity, where above a critical concentration the colloidal dispersion separates spontaneously into a chiral nematic liquid crystalline phase and solidifies into regularly twisted fibrillar layers that mimic the structural organization of helicoids in nature.About:

Review of Recent Research into Cellulosic Whiskers, Their Properties and Their Application in Nanocomposite Field
TL;DR: There are numerous examples where animals or plants synthesize extracellular high-performance skeletal biocomposites consisting of a matrix reinforced by fibrous biopolymers, which occur as whisker-like microfibrils that are biosynthesized and deposited in a continuous fashion.

Optimization of the isolation of nanocrystals from microcrystalline cellulose by acid hydrolysis
TL;DR: In this article, a rapid, high-yield process was proposed to obtain an aqueous stable colloid suspension of cellulose nanocrystals/whiskers. But the results of the process were limited by the concentration of MCC and sulfuric acid, the hydrolysis time and temperature, and ultrasonic treatment time.

The effects of shape on the interaction of colloidal particles
TL;DR: In this article, it was shown that colloids in general are apt to exhibit considerable deviations from Raoult's law and that crystalline phases retaining a fair proportion of solvent may separate from concentrated solutions.
Journal ArticleDOI
Twisted fibrous arrangements in biological materials and cholesteric mesophases.
TL;DR: A comparison is made between certain fibrous and regularly twisted biological materials and certain ordered liquids commonly called 'esteric liquid crystals' and examples of twisted arrangements and typical textures of cholesteric mesophases.
