Spherical cellulose nanoparticles preparation from waste cotton using a green method

Facile preparation of spherical cellulose nanoparticles: chemical hydrolysis of fibres with tension

“…However, our declared process itself has its contribution to the mass production of CNPs both in the industry and chemical laboratories due to its simplicity and efficiency. Furthermore, we claim its good yield due to less processing complications and possible use of short fibre waste for green processing as reported [9], because these short fibres also possess some amount of tension in them.…”

“…Nevertheless, many scientists reported the preparation of spherical CNPs by using the modified effect of common parameters; strong chemical hydrolysis, high mechanical agitation/sonication and elevated temperature. As reported, some of them performed milling before hydrolysis [10,22,40] while some have used cotton waste by textile mill [9] or waste cotton fabric [38]. Moreover, Han et al [11] reported the formation of spherical nanoparticles by highpressure homogenization.…”

Synthesis and Characterization of Nanocrystalline Cellulose as Reinforcement in Nitrile Butadiene Rubber Composites

“…The split in hydrogen bonding would contribute to the formation of larger surface area, which could easily be degraded by the thermal reaction. 41 In another study, by Meyabadi et al, 10 it was reported that the amount of charred residue was higher in samples with higher crystallinity. The increase in the concentration of HCl would provide more H + , which would strengthen the catalytic reaction of the glycosidic bonds between the nanocrystalline cellulose chains.…”

“…[5][6][7] This is also supported by several studies that performed the hydrolysis of cellulose from different sources, such as cotton and kenaf fibers, using sulfuric and hydrochloric acid. [8][9][10] The synthesis of NCC with HCl as a catalyst releases the hydronium (H + ) ion for the hydrolytic cleavage of glycosidic bonds in the cellulosic molecular chains within the amorphous region.…”

Controllable synthesis of one-dimensional isolated Ni 0.5 Zn 0.5 Fe 2 O 4 microtubes for application as catalyst support in RF heated reactors

“…Please insert Table 1 here A characteristic feature of the fibers is the presence of small channels along the radial direction [35,36]. Figure 3 (a) shows a characteristic SEM image of the template soaked with the nickel ferrite sol and then dried to form a gel.…”
