  2. Nanocellulose - Wikipedia

    en.wikipedia.org/wiki/Nanocellulose

    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.

  3. Nanotechnology for water purification - Wikipedia

    en.wikipedia.org/wiki/Nanotechnology_for_water...

    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 ...

  4. 3D cell culture in wood-based nanocellulose hydrogel

    en.wikipedia.org/wiki/3D_cell_culture_in_wood...

    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.

  5. Nanoparticle - Wikipedia

    en.wikipedia.org/wiki/Nanoparticle

    The most common example is the production of nanocellulose from wood pulp. [38] Other examples are nanolignin, nanochitin, or nanostarches. [39] Nanoparticles with one half hydrophilic and the other half hydrophobic are termed Janus particles and are particularly effective for stabilizing emulsions.

  6. Nanofiber - Wikipedia

    en.wikipedia.org/wiki/Nanofiber

    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.

  7. Biopolymer - Wikipedia

    en.wikipedia.org/wiki/Biopolymer

    The straight shape allows the molecules to pack closely. Cellulose is very common in application due to its abundant supply, its biocompatibility, and is environmentally friendly. Cellulose is used vastly in the form of nano-fibrils called nano-cellulose. Nano-cellulose presented at low concentrations produces a transparent gel material.

  8. Paper-based microfluidics - Wikipedia

    en.wikipedia.org/wiki/Paper-based_microfluidics

    This solvent-free technique allows the potential to create improvised paper-based μTAS. However, pencil-on-paper can also lead to a non-uniform deposition of graphite, limiting the performance of these hand-drawn circuits. [56] Additionally, even though the process can be automated, the repeated drawing procedure is poorly scalable.

  9. Cellulose - Wikipedia

    en.wikipedia.org/wiki/Cellulose

    Cellulose is the most abundant organic polymer on Earth. [6] The cellulose content of cotton fibre is 90%, that of wood is 40–50%, and that of dried hemp is approximately 57%. [7] [8] [9] Cellulose is mainly used to produce paperboard and paper. Smaller quantities are converted into a wide variety of derivative products such as cellophane and ...
