Fourier-transform infrared spectroscopy (FTIR) analysis of the filaments are shown in FigureS1in Supplementary Information. Our results show a slight increase in peak intensities with the increase of the CNC loading within the PLA matrix, which is in agreement with the literature52. The most signif...
Hydroxyethyl cellulose (HEC) is a cellulose-derived thickening and the gelling agent used in capsules containing hydrophobic drugs in order to improve dissolution of drugs within GI fluids in a method known as the hydrophilization method. This nonionic and water-soluble polymer is also used in ...
Cellulose, a natural, renewable, and environment friendly biopolymer, has been considered as a sustainable feedstock in the near future. However, only 0.3% of cellulose is today processed since it is not soluble in conventional solvents due to the strong hydrogen bonding network and highly ordered ...
Cellulose acetateis a modifiednatural polymer, biodegradable, obtained through theesterificationof cellulose with acetic acid, responsible for the substitution of cellulose hydroxyl groups by acetyl groups (Watabe et al., 2018). The degree of substitution (DS) significantly changes material properties, pa...
Paper is mainly made of cellulose (纤维素) This molecule (分子) makes up the cell walls of trees and many other plants. Because of its sturdy (结实的) structure, cellulose can 【小题1】 (use) repeatedly in paper making. Unfortunately, it also means that paper waste takes a 【小题2】...
If it is negative or zero, the ratio of toxicities (colloid: crystals) by contact action, measured quite soon after treatment of the insects, will be greater at a low temperature after treatment than at a high temperature after treatment; but if the coefficient is positive, the effect of ...
a combination of temperature and pressure. Cellulose (crystalline) is generally known to decompose at ~210 °C15,16at a saturated vapor pressure of 1.9 MPa. However, when the temperature increases from 100 to 210 °C, the pressure increases from 0.1 to 1.9 MPa, i.e., a ...

Pulp mills are potentially damaging to the environment and have been the focus of conflicts in many parts of the world. In the case of the installation of ... C Reboratti 被引量: 0发表: 2010年 AtCSLA 7 , a Cellulose Synthase-Like Putative Glycosyltransferase , Is Important for Pollen Tub...
Nevertheless, the extensive utilization of cellulose is actually warded off in that cellulose is extremely difficult to be dissolved owing to its enormous hydrogen bond network4–7. As such, many efforts have been made to develop novel and efficient solvents of cellulose. The developed solvents ...
