Traditional methods for chitin deacetylation require aqueous solution with high alkali content as reaction solvent, which generate huge environmental pressure the treatment of vast alkaline wastewater. In this work, glycerol, a nontoxic, biodegradable, and sustainable liquid from biodiesel production, is employed novel solvent at elevated temperature. The results showed that chitosan degree (DD) was up to 85.36 ± 1.04% corresponding viscosity-average molecular weight (MV) 30 874 1123 g mol–1...
Summary Bananas, a common fruit in our daily diet, often develop physiological disorders during the late ripening period, resulting browning, which reduces their suitability for consumption. In this study, we inhibited browning phenomenon by reducing oxygen concentration to improve storage period. Compared with banana treated high concentration, low had higher hardness and significantly delayed weight loss. The analysis showed that enhanced antioxidant capacity of skin cells maintaining DPPH...
Lignin is a type of biomass that generally found in nature and has wide range applications as functional material. A novel sorbent, aminated lignin (AL), was synthesized one-step method to improve its adsorption capabilities. The AL characterized through Brunauer–Emmett–Teller surface area analysis, thermogravimetric scanning electron microscopy, zeta potential analysis. small size had clear obvious porous structure with 47.1 m2·g−1, nearly ten times larger than kraft lignin, which 4.75...
In this study, a novel zwitterion-substituted lignin (ZL) containing amino and sulfonic acid groups was synthesized, ZL/Nafion composite membranes were fabricated as proton exchange membranes. Kraft modified using an aminosilane 1,3-propanesultone via continuous grafting reaction to provide zwitterionic moieties. Chemical structural analyses confirmed the successful introduction of zwitterion moiety into lignin. particular, surface charge ZL is positive in acidic medium negative basic...
Graphical Abstract Biosorbent from cellulose nanofibrils grafted with poly(m-aminobenzene sulfonate) (PABS) was prepared for effective detoxification and adsorption of Cr(VI) in an aqueous medium.
A green, effective, and feasible reaction for esterification of lignin with oleic acid in water at room temperature was investigated. surfactant-combined system (p-toluenesulfonic acid/4-dodecylbenzenesulfonic acid) designed to simultaneously solubilize kraft disperse the acid, producing microreactors esterification. Esterification using a higher 4-dodecylbenzenesulfonic dosage found be good option, an increasing had no effect on improving degree Structural characterization analyses...
Lignin is a renewable natural aromatic polymer that generated as co-product during lignocellulosic biorefinery processes, and it has been applied widely functional biomaterial. In this study, the adsorption behavior of Cd(II) Pb(II) metal ions was investigated via ion chelation using aminated lignins (ALs) with primary, secondary, tertiary amine groups. ALs exhibited optimal capacities in solution under neutral conditions due to their chelating, electrostatic, cationic–π interactions ions....
This paper addresses the difficult problem of measuring attitude a high-spinning projectile and presents novel method for estimating pitch yaw angles in flight. The is based on analysis external moment rotating during flight theoretical derivations obtained from dynamics’ equations. First, principle zero-crossing introduced, which explains process geomagnetic azimuth roll measurements by non-orthogonal sensor combination. Then, dynamics constraint equations between Euler flight-path angle,...
Abstract Recycled paper has become increasingly used as a raw material in the industry. However, hornification limits its application. Herein, effect of recycling on mechanical properties and microstructure khasi pine pulp was systematically studied. The deteriorated water retention value decreased after recycling. X-ray diffraction Fourier-transform infrared spectroscopy revealed that cellulose crystallinity increased partial cocrystallization occurred microfibrils. Through analysis...
As the uncertainty of transportation parameters in space charge simulation, it is our attempt to extract fundamental from experiments. In this paper, with design unipolar injection and migration experiment on basis measurement by PEA method, carrier mobilities positive negative LDPE have been estimated. The value calculated mobility charges agreement other estimation methods. Moreover, found that larger than LDPE, which might be owning less amount amorphous-crystalline interfaces process...
The addition of calcium carbonate to cigarette paper can enhance its combustion performance and apparent properties. However, it does come at the cost reduced strength. In this study, a flexible (FCC) was developed through in-situ formation on nanocellulose surfaces. incorporation FCC into offered potential improve filler retention while maintaining high results study demonstrated that when compared 30% precipitated (PCC), rate in increased by 31.5% used.
