Cellulose nanocrystals (CNCs), or nanocrystalline cellulose (NCC), are highly crystalline, rod-like nanoparticles. [6] [7] They are usually covered by negatively charged groups that render them colloidally stable in water. They are typically shorter than CNFs, with a typical length of 100 to 1000 nanometers. [8]
A nanocrystalline (NC) material is a polycrystalline material with a crystallite size of only a few nanometers. These materials fill the gap between amorphous materials without any long range order and conventional coarse-grained materials. Definitions vary, but nanocrystalline material is commonly defined as a crystallite (grain) size below ...
Wood is a naturally occurring composite comprising cellulose fibres in a lignin and hemicellulose matrix. [36] ... Amorphous and nanocrystalline powders obtained, for ...
Recent work with mining equipment manufacturers and the MSHA has shown that nanofiber filter media can reduce cabin dust concentration to a greater extent compared to standard cellulose filter media. [25] Nanofibers can be used in masks to protect people from viruses, bacteria, smog, dust, allergens and other particles. Filtration efficiency is ...
Nanocomposite is a multiphase solid material where one of the phases has one, two or three dimensions of less than 100 nanometers (nm) or structures having nano-scale repeat distances between the different phases that make up the material.
Comparative flame test of airplanes made of cellulose, carbon buckypaper and inorganic boron nitride nanotube buckypaper. [ 9 ] Buckypaper is one tenth the weight yet potentially 500 times stronger than steel when its sheets are stacked to form a composite. [ 1 ]

A paper battery is a battery engineered to use a paper-thin sheet of cellulose (which is the major constituent of regular paper, among other things) infused with aligned carbon nanotubes. [144] The potential for these devices is great, as they may be manufactured via a roll-to-roll process, [ 142 ] which would make it very low-cost, and they ...
