Summary: Fish skin, especially the sturgeon fish skin, has high flexibility and can provide good mechanical protection. It serves as a potential biomimetic design model for flexible and protective systems. The bending stiffness of the fish body decreases gradually from the anterior to the posterior region, indicating higher flexibility near the tail. Bony plates have an inhibitory effect on the bending deformation, especially in the posterior region. Moreover, the sturgeon fish skin significantly affects the flexural stiffness and promotes effective swimming motion.

Summary: This study examined the effect of caudal peduncle stiffness on tail angle of attack and propulsive force in fish. By using computational fluid dynamics analysis and experimental measurements in physical models, it was found that altering the stiffness of the base of the tail can modulate the motion phase relationship and affect thrust and efficiency. The findings highlight the significance of caudal peduncle stiffness in fish performance.

Summary: This study presents a time-efficient ultrasound method for assessing Achilles tendon mechanical properties. The method was validated through comparisons with manual frame by frame tracking, and showed similar results in measuring maximal tendon force, elongation, strain, and stiffness index. Additionally, the method was able to detect significant differences in tendon force and stiffness index between different groups of individuals. This analysis has the potential to accurately monitor changes in the mechanical properties of the Achilles tendon due to aging and altered loading.

Summary: Ultra-high molecular-weight polyethylene composites reinforced with Graphene Oxide, Nanodiamonds, and Short Carbon Fibres were characterized for their mechanical performance in tensile and short-term creep tests. The results showed a clear dependence of performance on the size scale/morphology of the reinforcements. Combining multiscale reinforcements resulted in an improvement that surpassed that of individual reinforcements.

Summary: This study investigated the effect of natural nanosilica on the mechanical properties and microstructure of geopolymer cement. The addition of 2 wt% nanosilica in the geopolymer paste significantly improved compressive strength, flexural strength, and fracture toughness but decreased direct tensile strength. Microstructure analysis showed the formation of C-A-S-H gel and the development of a compact and cohesive geopolymer matrix with the addition of 2 wt% nanosilica.

Summary: Cellulose nanopapers are made from sustainable cellulose nanofibers, but the full strength of the CNFs is not utilized in the resulting nanopapers. Basic principles of paper physics can be applied to reveal the relationships between CNF strength, bonding, and biological origin in nanopapers. The presence of hemicelluloses in NFC nanopapers strengthens the bonding between CNFs, similar to the primary cell wall of plants.

Summary: The present research investigated the mechanical properties of wood flour reinforced polyethylene polymer composites with varying wood flour size, aspect ratios, and mold injection temperature. Results showed that reducing the wood flour size decreased the tensile strength and modulus, flexural strength and impact energy, while increasing the flexural modulus. Additionally, increasing the injection molding temperature decreased the tensile strength and modulus, impact energy, while increasing the flexural strength and modulus. Thus, optimizing the injection molding temperature can improve the mechanical properties of the composite.

Summary: The study found that both LL-BFR and HL training resulted in comparable changes in patellar tendon stiffness, with no significant differences between the two groups. Increases in tendon cross-sectional area were also similar in both HL and LL-BFR. Muscle mass and strength increased significantly in both groups, with slightly higher changes in knee extension 1RM seen in LL-BFR.

Summary: The research focuses on characterizing the mechanical properties and morphology of polyester/coconut shell powder composites filled with corn husk fibre (CHF). Results show that increasing CHF content leads to higher flexural strength but lower tensile strength of the composite. The enhancement of the interfacial bonding between CHF-CSP-polyester and the reduction of fiber pull-outs contribute to the improved properties.
