Rice hull is a residue from agro-industry that can be used to produce nanocellulose. We produced nanocellulose from rice hulls through bleaching (with a 5% NaOH solution followed by a peracetic acid solution) and acid hydrolysis at a mild temperature (45ºC) followed by ultrasonication. We investigated the microstructure, crystallinity and thermal stability of these materials and studied their effects on the properties of starch films. After bleaching, the compact structure around the cellulosic fibers was removed, and the lignin content of the residue decreased from 7.22 to 4.22%. The obtained nanocellulose presented a higher crystallinity (up 70%), higher thermal stability than the raw material and lignin contents below 0.35%. The nanocellulose formed interconnected webs of tiny fibers (< 100 nm in diameter), which decreased the opacity, water vapor permeability and improved the mechanical properties when added as reinforcement in the starch films.

-Study on comparison the physicochemical properties of bunch press fibre cellulose (Bpfc) and cyclone fibre cellulose (Cfc) wastes from industry Crude Palm oil (CPO) have been performed. The physicochemical properties both of celluloses have been done such as the average degree of polymerization (DP), solubility properties, functional group analysis, thermal properties and X-ray diffraction patterns. The average degrees of polymerization (DP) have been obtained 2195 and 567 for Bpfc and Cfc. Bunch press fibre cellulose and cyclone fibre cellulose were soluble in cupriethylenediamine (CED). FT-IR analysis showed the same pattern of spectrum but differentintensities. Thermal stability of bunch press fibre cellulose and cyclone fibre cellulose remains stable up to a temperature of 250 °C. Glass transition bunch press fibre cellulose greater than the glass transition cyclone fibre cellulose and X-ray diffraction pattern shows the same pattern and intensity varies.

“…The morphological lowest hierarchical unit of cellulose has been demarcated as elementary fibrils (Figure 2). These fibrils are arranged into larger units called microfibrils, which are in turn finally assembled into cellulose fibers (Chinga-Carrasco, 2011;Brinchi et al, 2013). One of the most interesting properties of cellulose fibrils is the presence of discontinuous crystallinity along the length.…”

“…There are regions where cellulose chains are arranged in a highly ordered structure that results in a crystalline arrangement, which can then be flanked by a disordered chain qualified as amorphous region (Moon et al, 2011). These discontinuous crystalline regions on the cellulose fibrils are the precursors of crystalline nanocellulose (Brinchi et al, 2013). …”

Background: Cellulose is a ubiquitous, renewable and environmentally friendly biopolymer, which has high promise to fulfil the rising demand for sustainable and biocompatible materials. Particularly, the recent progress in the synthesis of highly crystalline cellulose-based nanoscale biomaterials, namely cellulose nanocrystals (CNCs), draws significant attention from many research communities, ranging from bioresource engineering, to materials science and engineering, to biological and biomedical engineering to bionanotechnology. The feasibility of harnessing CNCs' unique biophysicochemical properties has inspired their basic and applied research, offering much promise for new biomaterials with diverse advanced functionalities. Purpose: This review focuses on vital issues and topics on the recent advances in CNC-based biomaterials with potential, in particular, for bionanotechnology and biological and biomedical engineering. The challenges and limitations of CNC technology are discussed as well as potential strategies to overcome them, providing an essential source of information in the exploration of possible and futuristic applications of the CNC-based functional "green" nanomaterials. Conclusion: CNCs offer exciting possibilities for advanced "green" nanomaterials, driving innovative research and development in a wide range of fields, including biological and biomedical engineering.
