Summary: In this study, we synthesized Au nanoparticles (AuNPs) in chitosan (CTS) solution through chemical reduction of HAuCl4. CTS was further functionalized with glycidyl methacrylate (chitosan-g-glycidyl methacrylate/AuNP, CTS-g-GMA/AuNP) to improve the mechanical properties for cellular regeneration. Our nanocomposites showed excellent cellular viability and had a positive effect on cytokine regulation in the inflammatory and anti-inflammatory response of skin cells. After 40 days, the nanocomposite films exhibited better skin wound healing capacity and cosmetic aspects in comparison with a commercial film and the presence of collagen in the nanocomposite played a significant role in enhancing the overall regeneration effect of skin. Electrical percolation phenomena were utilized to optimize the performance of nanocomposites. Overall, chitosan-based Au nanocomposites showed great potential for skin wound repair.

Summary: A synthetic toolbox has been developed to create monodisperse core-shell and core-shell-shell particles composed entirely of different types of conjugated polymers. Seeded and fed-batch dispersion polymerizations based on Suzuki-Miyaura-type cross-coupling allow precise control over the interface between conjugated polymer phases, facilitating control over energy transfer phenomena. This new approach offers synthetic freedom for fine-tuning the optical properties of CPP, potentially enabling the synthesis of individual white light-emitting particles.

Summary: In this study, a new method was explored to graft glycidyl methacrylate (GMA) onto the surface of high-modulus carbon fiber (HMCF), which has extremely high chemical inertness. GMA was successfully grafted onto HMCF after acid activation synergized with ionization radiation, with a grafting degree of 22%. The hydrophilicity of the fiber was effectively improved after acid activation and grafting, and it showed good dispersibility in water. The surface structure of the fiber became highly disordered after grafting GMA. This work provides a new pathway for the modification of HMCF and is beneficial for obtaining high performance HMCF composites.

Summary: This study designed a new adhesive with better mechanical properties by grafting glycidyl methacrylate (GMA) onto (recycled) polyethylene (PE). The results showed that higher amounts of GMA led to higher functionalization degrees (FD), while higher amounts of dicumyl peroxide (DCP) resulted in lower FD due to more unfavorable side reactions. The influence of supercritical carbon dioxide (scCO(2)) on FD varied depending on the substrates used. Adjusting the screw speed and temperature profile had the highest positive impact on FD. All the grafted samples, especially the grafted RPE, showed higher stress levels compared to the non-grafted samples.

Summary: In this study, melt electro written (MEW) scaffolds of poly(e-caprolactone) PCL were decorated with anti-inflammatory yeast-derived peptide for skin wound healing. Thirteen different yeast-derived peptides were screened and analyzed using in vitro and in vivo assays. The selected peptide VLSTSFPPW (VW-9) was conjugated to the MEW scaffolds using carbodiimide (CDI) and thiol chemistry, with and without plasma treatment, as well as by directly mixing the peptide with the polymer before printing. The peptide-modified MEW scaffolds showed improved fibroblast and macrophage penetration and adhesion, increased cell proliferation, and superior anti-inflammatory properties.

Summary: This study investigates the preparation and properties of semi-interpenetrated nanocomposite films based on poly(vinyl alcohol) crosslinked with oxalic acid, reinforced with a flame retardant and silver-loaded zeolite nanoparticles. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX) analysis reveals the homogeneous distribution of the flame retardant and nanoparticles within the composite films. The flame retardancy of the composites remarkably improved with low phosphorus content, and the reinforced nanocomposites showed significant increases in tensile strength and elastic modulus. Additionally, samples containing silver-loaded zeolite nanoparticles exhibited enhanced antimicrobial activity.

Summary: The aim of this study is to investigate the effects of incorporating recycled fibers and a compatibilizer on the properties of composite materials. The results showed that the inclusion of recycled fibers decreased the tensile strength, elongation at break, flexural strength, and flexural modulus of the composites. However, the addition of a compatibilizer improved the mechanical properties of the composites containing 100% recycled fibers. Thermal analysis revealed good thermal stability of the composites, and SEM and EDX analysis confirmed the presence of the compatibilizing agent in the composite structure.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
