Summary: Closed-form bound and exact solutions to the five independent effective elastic constants of nanofiber-reinforced composites with Steigmann-Ogden interface effect are obtained in this work. The exact solution to the fifth effective elastic constant (me) is obtained in closed-form by the generalized self-consistent method. The study also reveals unexpected distinct bounds for the fifth effective elastic constant (me) of pure nanofibers compared to the four other effective elastic constants.

Summary: This paper reports a self-healing interface based on reversible hydrogen-bonded interactions in carbon fiber/polyvinyl alcohol composites. The surface functionalization of carbon fiber with dopamine allows for multiple reversible hydrogen bonds between polydopamine and polyvinyl alcohol at the interface. The CF-PDA/PVA composites exhibit significantly improved interfacial bonding force compared to CF/PVA composites, and maintain a relatively high self-healing efficiency after five cycles.

Summary: Basalt fibers (BFs) have desirable characteristics, but their low intrinsic interfacial properties have limited the performance of BFs-reinforced polymeric composites (BFRPs). Understanding the effects of incorporating BFs is critical for improving the performance of BFRPs. This review summarizes recent research progress on the interfacial behavior in BFRPs and discusses strategies for enhancing the interfacial adhesion of BFs within the polymeric matrix.

Summary: Copper-graphite composites modified with Ti3AlC2 by vacuum sintering were investigated. The addition of Ti3AlC2 coated with Cu improved the relative density, hardness, lubrication, and wear resistance of the composites. The incorporation of Ti3AlC2 also enhanced the presence of lubricating components and improved the interface bonding strength between the copper matrix and graphite. The Cu-graphite-Ti3AlC2 (Cu-coated) composites showed a relative density of 92%, a hardness of 94.2 HV, a friction coefficient of 0.175, and a wear rate of 1.28 x 10(-6) mm(3)/N center dot m.

Summary: This study proposes a new idea on the synchronous delay of starch digestion and retrogradation, and explores the regulation mechanism from the perspective of structural evolution. The results show that chestnut starch treated with hot extrusion and 8% catechins has the highest anti-retrogradation rate and the lowest rapidly digestible starch content at day 24. The slowing down of starch digestion is achieved by increasing the single/double helix, V-type crystallinity, and compactness of aggregates, while the retrogradation process is suppressed by inhibiting the packing of short-range ordered structure into long-range ordered structure. The main driving force for the interactions between flavonoid polyphenols and starch molecules is hydrogen bonding and van der Waals forces.

Summary: High-hydration hydrogels based on carbohydrate polymers and green preparation methods have recently attracted significant research attention. In this study, oxidized maize starch (OMS) was used to construct a 3D-OMS hydrogel via hot-extrusion 3D printing (HE-3DP). The effect of different OMS concentrations on printability, structure, and hydration properties was investigated. The results showed that 3D-OMS exhibited excellent hydration properties, with the maximum water absorption capacity and water holding capacity reaching 3013.43% and 93.53%, respectively. The 13% OMS concentration was found to be the most suitable for HE-3DP. Additionally, 3D-OMS demonstrated good biodegradability and cytocompatibility, suggesting its potential for developing starch-based biomedical hydrogels with excellent hydration properties through HE-3DP technology.

Summary: This study investigates the mechanism of starch-catechin interactions on rice starch digestibility during hot-extrusion 3D printing (HE-3DP). The results show that the HE-3DP processing with starch-catechin interactions can significantly decrease the starch digestibility by forming ordered structures. Molecular dynamics simulations reveal that catechin loosely attaches to starch chains, preventing starch from binding to the active pocket of pancreatic alpha-amylase. These findings provide useful structural information for reducing starch digestibility in the HE-3DP environment.

Summary: The study investigates the interaction between Catechin (EC) and starch isolated from Chinese chestnut. The addition of EC decreases the viscosity and retrogradation properties of chestnut starch (CS). It is found that EC can cause a looser gel structure of CS and reduce the relative crystallinity. These results suggest that EC is a promising ingredient to inhibit the retrogradation of starchy food.

Summary: This study investigated the retrogradation of chestnut starch and found that it can be inhibited by heat-moisture treatment (HMT) combined with flavonoid addition. Different flavonoids showed varying degrees of retardation, with epicatechin being the most effective. Structural analysis and theoretical calculations showed that the retardation effect was due to hydrogen bond interactions between starch and flavonoids, which prevented the aggregation of starch molecules. The findings of this study are important for the production of high-quality chestnut products.

Summary: The regioselective oxidation of native maize starch (NMS) using the laccase-TEMPO system resulted in the development of oxidized maize starch (OMS) with enhanced water absorption properties. The regioselective oxidation caused a shift from ordered to disordered structures, leading to a slight degradation of OMS chains and destruction of part of the short-range ordered structure, aggregate structure, and crystalline structure. However, the crystalline type, amorphous lamellae thickness, and morphology of the starch granules were largely maintained.

Summary: The nutritional design of personalized starchy foods has attracted attention in the field of food science. This study focused on designing the digestibility of starch by controlling its interaction with lipids. The results showed that thermal shear force in the 3D printing environment enhanced the interaction between starch and lipids, leading to increased enzymatic resistance. Adding stearic acid promoted the formation of a more ordered structure and improved the digestion of starch.
