A novel mechanical airborne filter to check the concentration gradient of airborne particles is discussed in this article. The system proposed here is experimented to detect the airborne microbes and its concentration analysed with the Chemical based Chromatography test. The proposed system which uses Silicon derivative material for the design of filter frame and an polymer material is coated over it. The polymerized coating is carried out to avoid the rapid oxidation of frame work. The system is equipped with the Contraction chamber and also the vacuum chamber equipped with chemical solvents. The entire Computational modelling carried out with Comsol multiphysics tool.

Cellulosic biomass hydrolysis yields a nanoscale substance known as nanocrystalline cellulose (NCC). Gel, liquid, or powder is adaptable to a variety of uses. Nanocrystalline cellulose has unique renewability, biodegradability, and mechanical and physicochemical qualities, and abundance boosts the material’s mechanical strength by many orders of magnitude when introduced into the material matrix (polymer, ceramic, or metal). Nanocrystalline cellulose is not related with any serious environmental issues because it is a natural substance. The progress of this biomaterial as a green and renewable biomaterial for the fabrication of lightweight and biodegradable composite materials gives further impetus. The current aim of nanocrystalline cellulose research is to optimise nanocrystalline cellulose characteristics for dispersion in hydrophilic and hydrophilic media. To assess the nanocrystalline cellulose reinforcing, antibacterial, stability, hydrophilicity, and biodegradability, imaging methods and protocols in complicated matrices will need to be developed. This review includes a discussion on nanocrystalline cellulose biocomposites.
