Summary: The focus of this study was on developing suitable GelMA hydrogel inks for 3D printing in tissue engineering applications. By exploring different degrees of GelMA methacrylation, concentrations of GelMA, and concentrations of photoinitiator, the researchers were able to determine the optimal formulations for the printing process. The presence of methacryloyl groups, the isoelectric point, hydrophilicity, mechanical properties, and structural integrity of the GelMA-based inks and 3D-printed scaffolds were thoroughly characterized to ensure their suitability for biological applications.

Summary: Inspired by spider silk spinning, a method for producing tough filaments using 3D bioprinting and salting-out of the protein was developed. A blend of natural polymer gelatin and viscoelastic G-polymer networks, as well as inorganic nanoparticles, was used to enhance stiffness, ductility, and 3D printing properties. The resulting self-healing nanocomposite hydrogel exhibited exceptional mechanical properties, biocompatibility, shear thinning behavior, and a controlled gelation mechanism for 3D printing.

Summary: One of the factors affecting the life expectancy of hanging scrolls is the storage environment. The study showed that the oxidation of painting paper, attributed to Cu2+, proceeded faster in a sealed tube environment compared to a moist heat aging method, due to increased hydrogen ion concentration accelerating acid hydrolysis and leading to faster degradation. This implies that storing a deteriorated hanging scroll in a closed system will degrade the painting paper faster than in an open system.

Summary: In order to understand the degradation behaviour of rolled hanging scrolls for future conservation treatments, this study evaluated the degradation-position profiles of naturally aged hanging scrolls and their model samples under different storage conditions. The results showed that the central positions of the scrolls tended to have lower pH and higher discolouration, indicating greater degradation. The influence of organic acids emitted from the paulownia wooden box was also investigated, and it was found that they primarily affected the periphery of the painting paper, with minimal migration towards the center. The analysis of naturally aged hanging scrolls revealed different degradation behaviours depending on the storage method.

Summary: This study measured the volatile organic compounds (VOCs) generated from naturally aged Japanese hanging scrolls and their model samples using SPME-GC-MS. Different painting papers and raw materials were found to have an effect on the degradation state of hanging scrolls. VOC-based degradation markers were identified and their applicability for evaluating the degradation of actual Japanese hanging scrolls was considered.

Summary: This study focused on the grafting polymerization of maleic anhydride and dibenzoyl peroxide with poly(epsilon-caprolactone) (PCL). The effects of stirring time, maleic anhydride amount, and benzoyl peroxide amount on the grafting ratio were investigated. The optimal conditions were determined, and the kinetic thermal decomposition and activation energy of the grafted polymer were studied. The results showed that grafting maleic anhydride hydrophilically enhanced PCL, facilitating the creation of a plastic-biomaterial composite.

Summary: Plastic waste is a global issue due to landfill overflow and pollution, leading to environmental concerns. To address this, biodegradable materials like poly-e-caprolactone (PCL) are introduced. However, PCL's natural decomposition rate is low. To increase decomposition rate, PCL is modified with maleic anhydride (MA) (PCL-g-MA), increasing hydrophilicity and amorphous region. Lipase hydrolysis experiments show that PCL-g-MA degrades faster than PCL. Morphological, thermal, and structural analysis support the hydrolysis reaction, confirming the effectiveness of the modification.
