Cellulose nanocrystals (CNC) are formed by the acid hydrolysis of native cellulose fibers, most commonly using sulfuric or hydrochloric acid. Disordered sections of native cellulose are hydrolysed and after careful timing, the remaining crystalline sections can be retrieved from the acid solution by centrifugation and dialysis against water.
Different types of nanocellulose materials available for water purification system includes Cellulose nanocrystals (CNC) and Cellulose nanofibrils (CNF). These are the rod-like nanomaterials whose size ranges from 100 to 2000 nm with the diameter of 2 to 20 nm.
Sonication can be used for the production of nanoparticles, such as nanoemulsions, [5] nanocrystals, liposomes and wax emulsions, as well as for wastewater purification, degassing, extraction of seaweed polysaccharides [1] and plant oil, extraction of anthocyanins and antioxidants, [6] production of biofuels, crude oil desulphurization, cell disruption, polymer and epoxy processing, adhesive ...
Nanochemistry is an emerging sub-discipline of the chemical and material sciences that deals with the development of new methods for creating nanoscale materials. [1] The term "nanochemistry" was first used by Ozin in 1992 as 'the uses of chemical synthesis to reproducibly afford nanomaterials from the atom "up", contrary to the nanoengineering and nanophysics approach that operates from the ...
Enzyme catalyzed reactions in biological applications are highly utilized for metabolism and processing large molecules. Nanoporous materials offer the opportunity to embed enzymes onto the porous substrate which enhances the lifetime of the reactions for long-term implants. [1] Another application is found in DNA sequencing.
The discovery of a highly ordered crystal nanostructure of amorphous C-S-H gel and the application of photocatalyst and coating technology result in a new generation of materials with properties like water resistance, self-cleaning property, wear resistance, and corrosion protection. [10]

Screen-printed electrodes on paper-based microfluidic devices have been used not only to develop biosensors for metabolites, [39] [41] [42] but also to detect bacteria [43] and heavy metals [44] in food and water. The scalabile nature of this process make it promising to create electrochemical devices at ultra-low cost suitable for field testing.
