Summary: In recent years, the research on biomaterials such as silk and cellulose has rapidly expanded due to their abundance, low cost, and tunable properties. This study investigated how the addition of reduced graphene oxide (rGO) affects the properties of cellulose-silk composites, such as carbohydrate crystallinity, protein secondary structure formation, and ionic conductivity. The results showed that the addition of rGO influenced the morphological and thermal properties of the composites and impacted the ionic conductivity by modifying the cellulose crystallinity and silk beta-sheet content.

Summary: Oxide ceramics are widely used as thermal protection materials. However, in extremely high-temperature environments, the growth of grain size can irreversibly damage the microstructure, leading to poor thermomechanical stability. This study proposes a novel strategy of phase transition modulation to control the grain growth in oxide ceramic nanofibers, achieving effective regulation of crystalline forms and size uniformity, and suppressing malignant growth of grains.

Summary: The study showed that as the oxidation degree of graphene oxide increased, it exhibited better dispersion in the matrix and improved interfacial interactions with epoxy resin, leading to enhanced mechanical properties of the nanocomposites. The tensile properties of the GO/epoxy nanocomposites at room temperature and liquid nitrogen temperature increased with the GO oxidation degree, reaching the highest performance at an appropriate oxidation degree. The toughening mechanisms of GO for epoxy nanocomposites at room temperature and liquid nitrogen temperature were analyzed and showed significant differences.

Summary: The study examined the effect of humidity on sheep wool irradiated by an accelerated electron beam. Results showed that wool sorptivity was significantly dependent on humidity, with 53% RH demonstrating the best Co(II) sorptivity. Excessive humidity and high dose of radiation led to decreased sorptivity due to radiolysis of water.

Summary: This study presents a rapid microwave reduction method for electrochemically-derived graphene oxide (EGO), which can transform EGO membranes into high-crystalline graphene membranes in just 3 seconds. The efficiency of microwave reduction is attributed to the unique molecular structure of EGO, which enables efficient microwave absorption and transient volumetric heating.

Summary: The purpose of this study is to investigate the impact of graphene oxide-silica nanocomposites on the mechanical properties, transport properties and microstructure of mortar, and to understand the mechanism by which GO-nanoSiO2 improves the properties of mortar. The results showed that adding 0.05 wt% GO effectively enhanced the compressive strength, fracture toughness and chloride penetration resistance of mortar. The addition of GO-nanoSiO2 also resulted in improved pore structure and reduced porosity, leading to improved impermeability. In the interface transition zone between aggregate and matrix, the presence of GO-nanoSiO2 inhibited crack propagation and improved the macroscopic fracture properties of mortar.

Summary: Electrically conductive polymer nanocomposite films containing reduced graphene oxide were prepared using aqueous emulsion-based techniques, with a focus on the impact of the polymer matrix. The study showed that subtle changes in the nature of the polymer matrix can significantly affect the properties of nanocomposites, with lower polarity monomer combinations leading to higher electrical conductivity.

Summary: This study aimed to evaluate the transport properties of a cement composite incorporated with graphene oxide (GO). The experimental results demonstrated that the addition of GO could significantly decrease water absorption, chloride migration coefficient, and chloride penetration depth in the cement composite specimens, while improving mechanical properties such as flexural strength and compressive strength. SEM analysis also showed that GO-cement composite specimens had a pore-filled structure. Overall, the incorporation of graphene oxide nano material effectively improved the transport properties of the cement composite.

Summary: In this study, a continuous wet-spinning strategy is proposed to rebuild wool keratin into compact regenerated bio-fibers with improved strength. By introducing dithiothreitol (DTT) to renovate disulfide linkage inside keratin polypeptide chains, a continuous backbone is formed as mechanical support. The wet-spinning technical parameters have been optimized to ensure the continuous preparation of high-strength regenerated keratin fibers.

Summary: The study demonstrated that coating decellularized umbilical cord arteries with graphene oxide (GO) can significantly improve their mechanical properties, bringing them closer to the current gold standard vessels used in coronary and peripheral artery bypass surgeries. Additionally, the GO coating did not compromise endothelial cell adhesion while reducing platelet and bacteria adhesion to the decellularized arteries, showing great promise in preventing thrombosis and infection.

Summary: The R&D and application of natural biomass resources is an important approach to address energy shortage and environmental pollution. In this study, wool keratin was modified using a natural antioxidant, alpha-lipoic acid, to improve the physical properties of regenerated materials. The research results showed that the modification effectively weakened the intra- and intermolecular forces of keratin, leading to a more orderly and compact structure.

Summary: With the growth of the world population and the improvement of living standards, the demand for global textiles is increasing rapidly. However, a large amount of waste wool textiles is being produced. The conventional treatment methods are not conducive to economic, environmental, and social development. To counter this problem, waste wool can be reused for insulation materials, composite materials, or water purification, and keratin extracted from waste wool can be used for high-value products. Continuous research and exploration are needed for effective management of waste wool resources.

Summary: The research showed that keratin solution easily forms a gel state under certain temperatures and concentrations, which is not conducive to the preparation of regenerated fibers. Through the analysis of the rheological properties of the blend solution, appropriate temperature and mass fraction were determined. Too much keratin in the solution would cause it to gel easily, which is not conducive to the preparation of regenerated fibers.

Summary: An environmentally friendly and effective shrink-proof finishing technology for wool fibers was developed using a treatment solution system of L-cysteine mixed with protease. The reduction performance of L-cysteine and its effect on wool were compared with those of other reagents, and it was found that L-cysteine has an obvious reduction and destruction effect on the wool scale layer. The L-cysteine/protease treatment solution system achieved rapid and effective shrink-proof finishing of wool without causing excessive pollution to the environment.
