“…Maize cobs and stalks have been used in the production of particleboards, while husks have been used in the preparation of low-density polyethylene composites [ 7 , 8 , 9 ]. In addition, according to literature data, cellulose or nanocellulose can be produced from maize crop residues [ 10 , 11 ]. Moreover, maize stover fractions can also be applied as substrates for the cultivation of oyster mushrooms or a feed source of ruminants [ 12 , 13 ].…”

In the last decade, an increasingly common method of maize stover management is to use it for energy generation, including anaerobic digestion for biogas production. Therefore, the aim of this study was to provide a chemical and structural characterization of maize stover fractions and, based on these parameters, to evaluate the potential application of these fractions, including forbiogas production. In the study, maize stover fractions, including cobs, husks, leaves and stalks, were used. The biomass samples were characterized by infrared spectroscopy (FTIR), X-ray diffraction and analysis of elemental composition. Among all maize stover fractions, stalks showed the highest C:N ratio, degree of crystallinity and cellulose and lignin contents. The high crystallinity index of stalks (38%) is associated with their high cellulose content (44.87%). FTIR analysis showed that the spectrum of maize stalks is characterized by the highest intensity of bands at 1512 cm−1 and 1384 cm−1, which are the characteristic bands of lignin and cellulose. Obtained results indicate that the maize stover fraction has an influence on the chemical and structural parameters. Moreover, presented results indicate that stalks are characterized by the most favorable chemical parameters for biogas production.

“…The environmental issues created by numerous uses of non‐biodegradable and non‐ecofriendly materials in a number of applications has pushed to researchers and scientists toward biodegradable and ecofriendly materials that must have no environmental impact. [ 1 ] In this context, cellulose (a natural polymer) has been the most suitable choice to satisfy such type of demand on account of its huge availability (most abundant material on the earth), biodegradability, recyclability and good strength. It has around 1.5 × 10 11 tons of annual worldwide production.…”

A novel approach including only one stage of ecofriendly treatment, by sodium bicarbonate, followed by mechanical grinding was used to isolate the nanofibers from waste sugarcane bagasse subjected to its characterization for the packaging applications. The result of dynamic light scattering (DLS) analysis was found in line with the result of transmission electron microscopy (TEM) to confirm the nanosize of developed nanofibers. The X-ray diffraction analysis showed the highest crystallinity of nanofibers than those of untreated and treated fibers. The removal of hemicelluloses and lignin from treated fibers and nanofibers was confirmed by Fourier transform infrared (FTIR) analysis. Moreover, a good thermal stability of nanofibers was also confirmed by thermogravimetric analysis (TGA). The optical properties (ie, absorbance and transmittance) in wavelength range 200 to 700 nm were also measured using UV-visible spectroscope. An excellent optical and antibacterial property against Escherichia coli (E. coli) and Bacillus bacteria along with better strength and stiffness was offered by the isolated nanofibers, which makes them the most suitable reinforcement to be used in polymeric composites for the packaging applications.

“…This was mainly caused by the absorption of water molecules by the hydrophilic groups in the cellulose molecules [32]. In addition, the peaks around 1202, 1162, and 1060 cm −1 represent the shear vibration peak, asymmetric vibration peak, and stretching vibration peak generated by CH 2 , C-O-C, and C-O on the cellulose epoxy structure C 6 , respectively [33,34]. The sharp peaks observed at 1370 cm −1 represent the C-H bending vibration.…”

Fabrication and Characterization of Cellulose Nanofiber Aerogels Prepared via Two Different Drying Techniques

et al. 2020

Studies on the influence of drying processes on cellulose nanofiber (CNF) aerogel performance has always been a great challenge. In this study, CNF aerogels were prepared via two different drying techniques. The CNF solution was prepared via existing chemical methods, and the resultant aerogel was fabricated through supercritical CO2 drying and liquid nitrogen freeze-drying techniques. The microstructure, shrinkage, specific surface area, pore volume, density, compression strength, and isothermal desorption curves of CNF aerogel were characterized. The aerogel obtained from the liquid nitrogen freeze-drying method showed a relatively higher shrinkage, higher compression strength, lower specific surface area, higher pore volume, and higher density. The N2 adsorption capacity and pore diameter of the aerogel obtained via the liquid nitrogen freeze-drying method were lower than the aerogel that underwent supercritical CO2 drying. However, the structures of CNF aerogels obtained from these two drying methods were extremely similar.
