Summary: In this study, the effects of ILs, DESs, and their components on cellulase were evaluated. The cellulase activity was preserved in ILs/DESs below 60 degrees C. Adding DES composed of betaine and ethylene glycol promoted cellulose dissolution and improved enzyme accessibility. DESs were found to be compatible with cellulase and have the potential to improve cellulase properties for the conversion of cellulose to fermentable sugars.

Summary: A series of cyanines with varying methine chain lengths and terminal groups were reacted with a specific cation after excitation in the NIR region, resulting in the generation of free radicals and conjugate acids. This study investigated the efficiency of free radical and cationic polymerization, as well as their combination as a hybrid system. By using NIR-LED exposure and varying the sensitizers, different photopolymerization efficiencies were achieved. The results showed that the combination of free radical and cationic polymerization can work effectively in hybrid systems.

Summary: A novel ionic liquid, [DBUC8]Cl, was synthesized and found to have stronger alkalinity than other imidazolyl ionic liquids, enabling more efficient dissolution of cellulose. Highly substituted cellulose acetate (CA) was successfully synthesized under mild conditions without the use of a catalyst, and a transparent cellulose acetate film (CAF) was obtained. The new DBU-derived ionic liquid offers a versatile platform for sustainable and efficient production of cellulose-derived bioplastics.

Summary: This study systematically investigated the degradation behavior of wood pulped cellulose in three phosphate-based ionic liquids under different conditions. The results showed that the degradation degree was influenced by dissolution temperature, dissolution time, and the type of IL used. Moreover, no reducing sugar was detected during the degradation of regenerated cellulose.

Summary: The study demonstrates that ionic liquid can improve the dispersion of cellulosic nanofillers and enhance the mechanical strength of vulcanizates. As the concentration of cellulosic nanofillers and ionic liquid increases, the viscoelastic rheological behavior of the vulcanizates is also affected.

Summary: The hydrogen bond theory was proposed to explain cellulose dissolution in ionic liquids with different alkyl chain anions. The length of the hydrogen bonds between cation and anion is the most important factor for determining the polarity parameter beta value of the ionic liquid and governing cellulose dissolution.

Summary: Fabricating regenerated cellulose fibers using ionic liquids is a novel and green technology. The study of the regenerated fiber forming mechanisms in conditions relevant to fiber spinning processes is necessary and meaningful. The effect of coagulating conditions on the properties of regenerated fibers was investigated, and the results indicated that regenerated cellulose fibers eventually developed differences in their internal structure and mechanical properties due to the different diffusion rates between spinning solution and coagulation bath. The surfaces of the regenerated cellulose fibers were homogeneous, indicating their potential in the application of textile fabrics.
