Summary: This study aimed to characterize the molecular structure of three types of gelatin, including salmon gelatin (SGel), salmon methacryloyl gelatin (SGelMA), and porcine gelatin (PGel). The results showed that functionalization affected the molecular weight and isoelectric point of gelatin. Functionalization and pH also influenced the molecular structure, rheological, and thermal properties of gelatin. The findings suggest that salmon gelatin methacryloyl presents high tunability as a biomaterial for biofabrication.

Summary: Wood has gained extensive attention in architecture, furniture, and other fields for its environmental friendliness and excellent mechanical properties. Inspired by the wetting model of lotus leaves, researchers have developed superhydrophobic coatings with strong mechanical properties and durability on modified wood surfaces. Various methods, such as sol-gel, etching, graft copolymerization, and layer-by-layer self-assembly, have been used to prepare superhydrophobic surfaces, which find application in biology, textiles, defense, and military industries. However, current methods for preparing superhydrophobic coatings on wood surfaces have limitations in reaction conditions and process control, resulting in low efficiency and insufficiently fine nanostructures. The sol-gel process offers a simple, cost-effective, and easily controlled method for large-scale industrial production of superhydrophobic coatings. This paper summarizes the research progress on wood superhydrophobic coatings, focusing on the sol-gel method with silicide as an example, and discusses different acid-base catalysis processes for preparing superhydrophobic coatings on wood surfaces. The latest developments in sol-gel-based superhydrophobic coatings at home and abroad are reviewed, and the future development of superhydrophobic surfaces is discussed.

Summary: Magnesium (Mg) alloys, as the lightest structural materials, have significant applications in weight reduction, aerospace, military equipment, energy saving, and emission reduction. However, the poor corrosion resistance of Mg alloys limits their wide usage. The silane-based sol-gel coating technology has been widely used to improve corrosion resistance due to its simplicity, customizable composition and structure, and excellent performance. To enhance the protection against corrosion, the modification of sol-gel coatings has become a hot research topic. This review discusses the modification methods of silane-based sol-gels on Mg alloy surfaces, including bare sol-gel, nanoparticles, corrosion inhibitors, and sol-gel-based composite coatings, and explores their application, development, and research strategies.

Summary: ZrC-SiC composite ceramics with varying Zr/Si molar ratios were prepared using sol-gel method. The composites were characterized by various techniques including FT-IR, XRD, TGA, TEM, SEM, Raman spectroscopy, and EDS. The results showed the formation of a macromolecular network structure in the composites, with Zr atoms crosslinked with Si in corresponding proportion. After annealing, ZrC powder uniformly covered the surface of SiC ceramics, with high-crystallinity graphite carbon covering the ZrC powder.
