Summary: This study investigates the effects of two different ball milling methods on the sintering shrinkage behavior and bonding of WC-Si3N4 composite. The results showed that the powder prepared by the method of ball milling in two stages has better mechanical properties, and the maximum shrinkage rate during sintering increases as the WC content decreases. Additionally, the mechanical properties of samples prepared by the two-stage ball milling method are better than those prepared by the one-stage ball milling method.

Summary: This study investigated the production and evaluation of self-compacting concrete (SCC) made with high volumes of non-clinker binders. The effects of fly ash and slag on SCC properties were examined, including workability, strength development, thermal properties, and shrinkage properties. The results showed that a high volume of fly ash reduced the compressive strength of SCC, but improved thermal and shrinkage properties. Slag replacement was found to be the most effective in maintaining concrete strength and improving thermal and shrinkage properties. The synergistic effect of fly ash and slag resulted in better mechanical properties compared to using only fly ash as OPC replacement in SCC.

Summary: Thermoplastic all-polymer composites, made from the same material for reinforcing fibers and matrix material, have become increasingly popular due to their potential for recycling compared to traditional composites with inorganic reinforcements. This study proposes a new preparation concept for all-polyamide composites using a hybrid yarn of polyamide-6 and polyamide-66 fibers. By embroidering the hybrid yarn in the desired direction on a polyamide-6 fabric, composites with desired reinforcing fiber orientation can be prepared, maintaining the integrity of the reinforcing and unmelted PA66 fibers embedded in a molten PA6 matrix during thermoforming at 230 degrees C. The mechanical properties of these composites, including different matrix-to-reinforcement ratios and reinforcing fiber orientations, are characterized using quasi-static and high-speed tensile tests as well as penetration tests.

Summary: Aramid/carbon fiber hybrid reinforced polymer composites were prepared to improve the toughness of carbon-fiber-reinforced polymer composites. The hybrid fiber improved the thermal stability of the composites, but decreased the ductility with increasing carbon fiber content. The strength of the composites followed the rule of mixtures and exhibited a positive hybrid effect. Scanning electron microscopy analysis showed that the failure modes of the composites were mainly debonding and fracture of the fibers and resin matrix.

Summary: Lightweight engineering cementitious composites (LECCs) have potential for weight-sensitive structures, but the large quantities of cement used cause shrinkage and decrease efficiency. Zeolite as an internal storage source was investigated to compensate for water loss, improving the mechanical properties and reducing drying shrinkage of LECCs. Microscopic analysis showed that the presence of zeolite promoted further hydration of the cementitious products, resulting in a denser microstructure.

Summary: Separator is a crucial component in lithium-ion batteries (LIBs) as it significantly affects the electrochemical performance of the battery. However, the poor electrochemical performance of commercial LIB separators limits their use in electric vehicles and energy storage systems. This issue can be addressed by using different types of polymer separators and fabrication technologies. Electrospinning technology has gained attention for its ability to design new separator materials with high porosity, surface area, electrolyte uptake, and ionic conductivity. Among various polymeric separators, polyvinylidene fluoride (PVDF) and its copolymers are extensively used due to their desirable properties. This review discusses the impact of different PVDF-based electrospun separators on battery performance and highlights recent developments in improving electrochemical performance.

Summary: The search for sustainable plastics is driven by the environmental pollution issues associated with petrochemical-derived plastics. Bioplastics, such as poly(lactic acid) (PLA), are increasingly being used in packaging due to limited fuel resources. However, poor ductility and gas barrier characteristics limit the use of PLA as food packaging material. This study aims to overcome these limitations by fabricating PLA/polyethylenimine-modified mesoporous silica (PEI-MS) composites. The influence of PEI content in MS and wt % loadings of optimized PEI content in MS on the properties of PLA is investigated in detail. The results show that PEI-MS modification improves the thermal stability and mechanical properties of PLA.

Summary: This paper discusses the influence of increasing concentration of carbon black (CB) on the physical and mechanical properties of SBR/BR rubber blends. The partitioning of CB towards the BR phase is quantitatively determined and confirmed using dynamic mechanical analysis (DMA) and solid-state nuclear magnetic resonance spectroscopy (SS-NMR spectroscopy). The results show that increasing CB concentration increases its partitioning towards the BR phase, affecting the properties and dispersion characteristics of the material.

Summary: This study reports on the self-healing capability of a plant-based bioepoxy resin by incorporating reversible ionic groups using a simple blending process with ionic liquid. The interaction between hydroxyl groups in the resin and the ionic groups in the liquid was found to be reversible, allowing for instantaneous self-healing of minor cracks. Tensile and nanoindentation tests revealed the retention of mechanical properties after self-healing, with the self-healed samples retaining approximately 42% and 53% of their tensile strength and elongation at break.

Summary: In this research, the hybrid reinforcements of silica with either graphite or graphene oxide in natural rubber were studied. The addition of GO/SiO2 with a 3:1 ratio showed a synergistic reinforcement effect, significantly improving both strength and modulus while maintaining decent strain at break levels. The experimental data correlated well with the Guth Gold model, suggesting that filler/matrix interactions primarily govern the mechanical properties. The calometric response of the nanocomposites at the glass transition was analyzed, and the 3:1 GO/SiO2 composition showed the highest glass transition temperature and the most efficient filler intercalation.
