Summary: This article introduces stiff and tough biocomposites prepared by in-situ polymerisation of poly (methyl methacrylate) and ductile non-dry flax fibres. The results show that composites processed with non-dry fibres have comparable shear strength but higher elongation at failure and toughness compared to composites processed with oven-dried fibres. Additionally, non-dry flax fibres significantly increase the perforation energy of flax-PMMA composites under low-velocity impact. The study also investigates the effect of non-dry fibres on fatigue life and failure mode of the composites.

Summary: The research focused on characterizing mechanical alterations at the reinforced interface of bituminous layers for different mixtures in terms of axial stiffness and adhesion quality. The proposed methodology of complex modulus test was found to be a practical tool for comparing rheological behavior of interfaces with dissimilar conditions. The 2 Springs, 2 Parabolic creep elements, and 1 Dashpot (2S2P1D) model was reliable in predicting the mechanical behavior of any type of interface at high frequencies or low temperatures.

Summary: This study investigates the performance of composite pressure vessels under damaged and undamaged conditions, providing insights into their reliability and residual strength capabilities. The results demonstrate that the damage profile and its effect on compressive strength are similar between damaged and non-damaged cylinders. When subjected to quasi-static compression, the polyethylene liner absorbs enough elastic strain energy to recover without plastic deformation. Additionally, quasi-static compression has little to no influence on the axial strength of the cylinders. The damage characterization reveals fiber breakage, delamination, local buckling, and brooming failure. This study has direct implications for the safety design tolerances, manufacturing strategies, and operational failure conditions of composite overwrapped pressure vessels (COPVs).

Summary: The paper reviews heat transfer correlations for cylinder-piston, reciprocating machinery, identifying around 25 applicable correlations, mostly created for internal combustion engines. These correlations generally describe the convective heat transfer coefficient on the cylinder wall surface, influenced by factors such as gas parameters, gas composition, piston velocity, and position.

Summary: This study investigated the fatigue behavior of CNT/Al composites with different structures under different fatigue conditions, and found that CNT increased fatigue strength through load transfer effect but failed to improve it under tension-compression fatigue. The principal damage mechanism was strain localization in the CGs.

Summary: The combustion of ammonia in internal combustion engines (ICE) leads to high concentrations of nitrogen-related exhaust emissions, including nitrous oxide (N2O) and nitrogen oxides (NOx). The study shows that the incomplete combustion of ammonia contributes to the increased formation of N2O. The fuel composition affects the contribution of different mechanisms to NOx emissions, and thermal NO contribution becomes fuel-independent at high temperatures. Decreased carbon content in the fuel results in lower soot concentrations. In fuel-rich regimes and fully burned conditions, low concentrations of NOx and N2O emissions are observed.

Summary: In this study, a series of smart internal bio-glues were developed by integrating o-nitrobenzene modified biopolymers with up-conversion nanoparticles (UCNPs). The prepared smart bio-glues can undergo gelation and induce strong tissue adhesion under both dry and wet conditions upon irradiation by near-infrared (NIR) light. These NIR light-responsive bio-glues with deeper tissue penetration ability exhibit good biocompatibility, excellent hemostatic performance, and the potent ability to accelerate wound healing for both external and internal wounds.

Summary: Through the compression-extrusion process, a fine grain and weak texture symmetric ZK61 magnesium alloy rod was achieved. The compression stage activated {10-12} twinning deformation leading to significant grain refinement, while in the extrusion stage, twinning gradually decreased and basal slip dominated the deformation, resulting in the formation of a weak texture.

Summary: The deformation behavior of an extruded Mg-Zn-Zr alloy in plate/sheet form was investigated, and it was found that the loading directions and initial texture significantly affected the flow stress and strain hardening rate, leading to differences in ultimate compressive and tensile strength. Anisotropy in the material was attributed to factors such as fine-grained size, twinning dependencies on strain path loading, and texture.

Summary: This paper studies composite structures, specifically a fiberglass reinforced structure. Previous research has treated these structures as homogeneous anisotropic laminated plates, but this paper treats the fiberglass and polyethylene matrix separately. By using this method, the plasticity of the polyethylene and the fracture stress of the fiberglass can be considered, allowing for the prediction of fiberglass fracture. Analytical and numerical methods are used to investigate the mechanical behavior of FGRFP under real-life loadings, and the results are verified through experiments.

Summary: This work presents the complexation of DNA with thermoresponsive microgels. Cationic microgels complexate spontaneously with DNA, while anionic microgels require the presence of multivalent cations to promote complexation. The presence of Ca2+ induces changes in the interaction and surface conformation of anionic microgels.

Summary: By mimicking the unique corrugated driving structures in the Bird's Nest Fern, we have developed a 3D kirigami structure that can be fabricated by simple shearing and stretching. This structure exhibits a unique load responsiveness, leading to an increase in the water collection ratio with the external load. It possesses a 3D array configuration to enhance flow velocity for efficient droplet condensation, and geometric and wetting gradients for spontaneous and rapid transport of condensate droplets, resulting in a high water collection efficiency. The water collection ratio can reach 3.45 times that of a pure iron sheet by only changing the geometric structure, and even reach 4.58 times with the assistance of wetting gradients.
