Nanocellulose is a term referring to a family of cellulosic materials that have at least one of their dimensions in the nanoscale. Examples of nanocellulosic materials are microfibrilated cellulose, cellulose nanofibers or cellulose nanocrystals. Nanocellulose may be obtained from natural cellulose fibers through a variety of production processes.

It has a hollow tube structure consisting of about 35% cellulose and nanocellulose, 22% xylan and 21.5% lignin in the dry fibre. Also pectin and wax. Also pectin and wax. The fibre is hydrophobic due to a fairly high fat content and is not wetted by water, but is absorptive of oil at a level of 40 g/g or 40 oz/oz of fibre from an oil suspension ...
Nanocellulose is instead derived from wood pulp that has been processed to create extremely small, nanoscale fibers. These fibers can be used to create a hydrogel, which is a type of material that is made up of a network of cross-linked polymer chains and is able to hold large amounts of water.
Curran is a microcrystalline nanocellulose fibre derived from the pulp of root vegetables. It was developed by Scottish scientists David Hepworth and Eric Whale, with funding from the Scottish Government. The sources of root vegetable pulp used to manufacture Curran include carrots, sugar beets, and turnips.
Carboxymethyl cellulose (CMC) or cellulose gum [1] is a cellulose derivative with carboxymethyl groups (-CH 2-COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone.
The wet strength of paper and paperboard is a measure of how well the web of fibers holding the paper together can resist a force of rupture when the paper is wet. Wet strength is routinely expressed as the ratio of wet to dry tensile force at break.
Cranston returned to Canada in 2011, and joined the faculty at McMaster University.Her research considers the colloid and surface chemistry of biopolymers. [3] She has particularly focused on the development of nanocellulose microstructures [4] that can be used in a broad range of applications, including packaging, electrical components and cosmetics.
