Summary: The massive accumulation of plastic waste has had a serious negative impact on the human living environment. This study focuses on replacing traditional petroleum-based polymers with biobased and biodegradable poly(L-lactic acid) (PLLA) to solve this problem. The researchers used a melt extrusion-stretching method to fabricate biodegradable PLLA/poly(butylene adipate-co-butylene terephthalate)/carbon nanofiber (PLLA/PBAT/CNF) blend composites with high thermal conductivity and excellent mechanical properties. The results showed that the incorporation of the extensional flow field induced multioriented microstructures in the composites, which improved their thermal conductivity and mechanical properties. The oriented PLLA molecular chains and crystallites formed during the process further enhanced the thermal conductivity and heat resistance of the samples.

Summary: In this study, bamboo pulp was treated with citric acid-choline chloride deep eutectic solvent to simultaneously fibrillate and esterify it. Higher temperatures and longer treatment times led to increased esterification, resulting in CNFs with a higher carboxyl group content. However, these conditions also led to decreased yields and smaller CNF diameters. The CNFs with higher carboxyl group content showed effective inhibition against E. coli and S. aureus bacteria. Based on comprehensive considerations, treatment at 120 degrees C for 24 h was found to be the optimal condition, resulting in CNFs with a carboxyl group content of 0.31 mmol/g, a diameter of 8 nm, and significant inhibition of E. coli (81.7%) and S. aureus (63.1%). In addition, the CNFs obtained under the optimal condition were found to enhance the tensile strength of polyvinyl alcohol (PVA) films by 74%, making them a favorable additive for composite films.

Summary: We report the basic sheet properties of divalent phosphorylated cellulose nanofibers (CNFs) with different phosphorus contents and counterion types. The counterion exchange from sodium ions to calcium or aluminum ions greatly enhances all examined sheet properties of CNF sheets. The phosphorus content only has significant influences on conditioned tensile and fire-retardant properties. Compared to CNF sheets with monovalent carboxy groups, CNF sheets with divalent phosphate groups are superior in terms of wet tensile properties and fire-retardant properties.

Summary: In this study, a self-powered UV photodiode on a green substrate was successfully developed using a highly conductive AZO film and different electrode designs. The paper-based Schottky photodiodes operated without external power, with the Au-ZnO-AZO-Al structure showing improved response and faster speed compared to the Au-ZnO-Al structure. The enhancement in performance was attributed to the strong electric field in the ZnO-AZO n-n+ junction and the favorable ohmic contact between AZO and Al electrodes.

Summary: Recently, the preparation and applications of starch-based bio-latexes are facing challenges in terms of high concentration, high colloidal stability and high rheological performance. This study proposes a practical and effective strategy using cationic cellulose nanocrystals (CCNC) as carriers of alpha-amylase for the preparation of starch-based bio-latex (SBL) with improved hydrolysis efficiency even at 50 wt% concentration. The immobilized alpha-amylase on CCNC can regulate starch hydrolysis behavior and enhance colloidal stability and viscoelasticity. Additionally, CCNC provides multifunctional roles as dispersants, nano-fillers, and enhancers within starch colloids, improving the rheological properties and printability of SBL in pigmented coating and printing performance. This study offers a promising approach for efficient production of high-performance starch-based bio-latex and enhances the applications of cellulose nanocrystals in biomaterials.

Summary: DESs were synthesized and tested for their solubilisation of two industrial lignins. The results showed that DESs with higher HBD content, shorter carbon chain length and fewer functional groups were more effective in dissolving lignin. DESs containing carboxyl groups were found to be particularly effective in breaking beta-O-4 bonds and solubilizing lignin. High temperature and suitable water content were also observed to promote lignin solubilization. The pretreatment of poplar and maize straw with specific DESs showed good solubilization of lignin, with ChCl/FA(1:3) being the most effective in dissolving poplar lignin and maize straw lignin, achieving lignin solubilization of 82% and 57% respectively. Overall, these findings indicate the great potential of DESs as solvents for lignin dissolution.
