Summary: A modified NiCo2O4 composite electrocatalyst is prepared with chitosan matrix to enhance the electrooxidation of ethylene glycol. The synergistic effect between spinel oxide and chitosan is evaluated through a comparative study with pristine NiCo2O4. The electrochemical activity towards ethylene glycol electrooxidation is investigated in an alkaline solution, and the long-term stability of the composite electrode is measured. Kinetic parameters and adsorption energies are calculated, and the interaction between spinel oxide and chitosan is studied using a Forcite model.

Summary: A water-soluble chitosan-nerol derivative (CS-N) was synthesized to enhance the antibacterial activity and solubility of chitosan. The CS-N showed superior antibacterial activity against Escherichia coli and Staphylococcus aureus, as well as significant antioxidant activity. Moreover, it did not exhibit cytotoxicity towards HaCaT cells. This study provides a promising approach for the development of chitosan derivatives with potential application in pharmaceutical, food, and cosmetic industries.

Summary: In this study, excellent strength regenerated alginate composite fibers were prepared using a simple blending strategy. By grafting poly(ethylene glycol) onto cellulose nanocrystals, the mechanical properties of the fibers were improved and the microstructure became denser. Additionally, increasing the molecular weight of PEG also enhanced the salt tolerance and antibacterial activity of the composite fibers.

Summary: In this study, a green reaction route for the preparation of BiVO4/g-C3N4 composite was constructed using an acetic acid and reusable ethylene glycol system combined with the microwave method. The prepared photocatalyst exhibited high performance in removing pesticides and dyes from agricultural and urban runoff. The establishment of the ethylene glycol and acetic acid system provides a new perspective for the replacement of strong acids in the preparation of BiVO4-based photocatalysts.

Summary: Graphene Oxide (GO) has been difficult to translate into clinical applications due to non-specific protein adsorption and poor stability. This study establishes a new method for functionalizing GO with poly(ethylene glycol) (PEG) using the Steglich esterification reaction, improving the stability of GO and PEG interaction through covalent bond formation. The proposed methodology successfully demonstrates the attachment of PEG to the hydroxyl group of GO sheets, as confirmed by spectroscopic and microscopic analysis.

Summary: This study proposes the use of Passerini three-component polymerization (P-3CP) to modify polyethylene glycol (PEG) for solid polymer electrolytes (SPEs). The introduction of side groups via P-3CP successfully suppresses the crystallinity of PEG and improves the ionic conductivity and lithium ion transport properties of the resulting polyesters.

Summary: The cellulose nanofibers (CNF) obtained through high-pressure microfluidization were oxidized with 2,6,6-tetra-methylpiperidine-1-oxyl (TEMPO) to facilitate the grafting of ethylene glycol methyl ether acrylate (EGA). The analysis showed a more efficient grafting of EGA oligomers on the surface of TOCNF, resulting in increased hydrophobicity and reduced porosity. Despite a similar swelling ratio to original CNF grafted with EGA, TOCNF-EGA demonstrated good cytocompatibility and compression strength, making it suitable for applications in regenerative medicine.

Summary: This study aimed to enhance the enzymatic digestion of sugarcane bagasse (SCB) using different NaOH-catalyzed ethylene glycol (EG) pretreatments combined with water-soluble sulfonated lignin (SL). The results showed that the one-pot pretreatment of 10%NaOH/EG was more effective than single NaOH or EG pretreatment, or two-step pretreatment. The highest glucose yield was achieved with SCB pretreated with 10%NaOH/EG at 130 C for 60 min and 72 h enzymatic hydrolysis. The addition of SL significantly reduced cellulase dosage and hydrolysis time while maintaining a high glucose yield of 90.4%.

Summary: As a promising approach in translational medicine, the decellularization of discarded livers to produce bioscaffolds that support recellularization has potential in overcoming the limitations of conventional liver transplantation. In this study, the researchers investigated the use of matrix metalloproteinase (MMP) inhibition to preserve the extracellular matrix (ECM) during liver decellularization. The results demonstrated that the application of an MMP inhibitor significantly improved the preservation of ECM components and mechanical properties of the bioscaffolds, which supported cell viability and function in vitro. The study also confirmed that the MMP inhibition led to the inhibition of MMP2 and MMP9, providing a novel method to enhance ECM preservation during liver decellularization.

Summary: Human skin equivalents (HSEs) play a crucial role in tissue engineering. This study introduces a 3D-printed culture insert to apply a static radial constraint on HSEs and examines its effects on tissue characteristics. The results show that the diameter of the culture insert significantly influences tissue contraction, fibroblast and matrix organization, keratinocyte differentiation, epidermal stratification, and basement membrane formation. This study provides important insights for the design of skin tissue engineering.

Summary: This paper reviewed the primary methods for improving the overall properties of biodegradable zinc stents. It discussed the mechanical properties, degradation behavior, and biocompatibility of various improvement strategies. Alloying was found to be the most common, simple, and effective method for improving mechanical properties. Deformation processing and surface modification further improved the mechanical properties and biological activity of zinc alloys. Meanwhile, structural design could endow stents with special properties. Manufacturing zinc alloys with excellent properties and exploring their interaction mechanism with the human body are areas for future research.
