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.
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.

Example of a cellulose nanofiber network. Nanofibers are fibers with diameters in the nanometer range (typically, between 1 nm and 1 μm). Nanofibers can be generated from different polymers and hence have different physical properties and application potentials.
The most common example is the production of nanocellulose from wood pulp. [39] Other examples are nanolignin, nanochitin, or nanostarches. [40] Nanoparticles with one half hydrophilic and the other half hydrophobic are termed Janus particles and are particularly effective for stabilizing emulsions.
This bio-based nanocellulose filter has more advantage to conventional filters. Nanocellulose is prepared by various methods such as sulphuric acid hydrolysis and mechanical grinding method. Water purification system is mainly based on the principle of absorption. For the absorption of anionic metal species, the nanocellulose materials are ...
Cellulose nanocrystals self assemble into helicoidal thin films, the pitch angle between the layers can then be modified via solvent processing. The resulting nanocellulose films, which have a Bouligand structure, can be manipulated to achieve various effects on the material properties.
In this process, the ink is transferred onto areas of the paper-based microfluidic channels using a stencil. Dungchai et al . demonstrated electrochemical sensing using screen-printed carbon ink for the working and counter electrodes and silver/silver chloride ink as the reference electrode at the end of the microfluidic channel.

Attachment of the cellulosome to its substrate is mediated by a scaffoldin-borne cellulose-binding module (CBM) that comprises part of the scaffoldin subunit. Much of our understanding of its catalytic components, architecture, and mechanisms of attachment to the bacterial cell and to cellulose, has been derived from the study of Clostridium ...
