Preparation and liquid crystalline properties of spherical cellulose nanocrystals.
A novel kind of spherical cellulose nanocrystal (SCNC) suspension was prepared by hydrolysis of microcrystalline cellulose with a mixture of sulfuric acid and hydrochloric acid under ultrasonic treatment. The mechanism of SCNC formation and the liquid crystalline properties of their suspensions were investigated. A suspension of spherical particles was usually inclined to form crystallization c...
متن کاملLiquid crystalline cellulose-based nematogels
Physical properties of composite materials can be pre-engineered by controlling their structure and composition at the mesoscale. However, approaches to achieving this are limited and rarely scalable. We introduce a new breed of self-assembled nematogels formed by an orientationally ordered network of thin cellulose nanofibers infiltrated with a thermotropic nematic fluid. The interplay between...

متن کاملLiquid Crystalline Phases of DNA
The DNA molecule is the support of the genetic information. It is a right-handed double helix, 22 angstrom in diameter, and 50 nm in the persistence length. The two strands of the helix are complementary in their nucleotide sequence with about 10 nucleotide pairs per helical turn. DNA is a long and strongly charged heteropolymer. It bears on average one elementary negative charge per each 0.17 ...
متن کاملPhototunable liquid-crystalline phases made of nanoparticles.
The properties of liquid-crystalline (LC) hybrid systems made of inorganic nanoparticles grafted with photosensitive azo compounds are presented. For materials with a large density of azo ligands at the surface, the LC structure can be reversibly melted by UV light, and the return to the LC state does not require the absorption of visible light. For systems with a lower density of azo ligands, ...
