Summary: This study investigated the effects of different aggregate combinations on the long-term mechanical and shrinkage properties of fully recycled aggregate concrete (FRAC). It was found that using fully recycled aggregate combinations had negative effects on the concrete properties, and the effect caused by fully recycled aggregate combination was higher than the sum of the effects caused by fully recycled coarse aggregate and fully recycled fine aggregate combination. Additionally, the study examined the impact of recycled powder (RP) on FRAC properties and found that RP content affected the mechanical properties and shrinkage strain of FRAC.

Summary: The market for plant-fibre reinforced composites has been growing steadily due to environmental legislation and global warming effects, but uncertainties regarding defects in plant fibres decrease mechanical properties at the composite scale. Finite element modelling has emerged as a crucial tool in understanding these defects, particularly in complex plant fibre ultrastructures compared to synthetic materials. Through a top-down and multi-scale approach, this review addresses advanced testing methods and numerical approaches to capture the complex mechanical behaviour of plant fibres.

Summary: Protein-based hydrogels are extensively studied in biomaterials research due to their ability to mimic living tissues and the extracellular matrix. However, methods for controlling their mechanical properties are limited, mainly focusing on elasticity and often with unrealistic characterization. This study develops a computational model to characterize the mechanical behavior of two protein-based hydrogels and compares it with experimental results. The model utilizes the Finite Element Method, combining hyperelastic and viscoelastic models, and the first order Ogden model with a viscoelastic model defined in Prony parameters performs the best in reproducing the observed strain-stress response and stiffness change.

Summary: With the increasing severity of electromagnetic pollution, there is an urgent need for efficient electromagnetic interference (EMI) shielding materials that are lightweight, possess elegant mechanical behavior, and have a designable structure. The use of multiple reflections within materials can effectively improve the EMI shielding efficiency, making it a priority when designing EMI shielding materials. Inspired by the fabrication of toasts, the dough can be stretched into extremely thin sheets, resulting in the micro components being arranged in-plane within the porous carbon, leading to an anisotropic EMI shielding performance. Additionally, the replacement of water with graphene oxide (GO) solution and the stretching of GO@dough into thin sheets with in-plane oriented GO nanosheets further enhance the EMI shielding performance.

Summary: Recently, there has been great interest in graphene aerogels due to their outstanding properties. However, their weak compressive mechanical performances often limit their further applications. In this study, a novel approach was proposed to enhance the compressive stiffness of graphene aerogels inspired by the structure of leaves. A type of CNT sandwiched graphene aerogels (CSGAs) was prepared using a simple freeze-drying method. Compressive testing results showed that the sandwiched CNTs effectively provided mechanical support, and the compressive properties of CSGAs were also influenced by the CNT content. Coarse-grained molecular dynamics (CGMD) simulation revealed that when the appropriate number of CNTs was present between graphene nanosheets, they formed a stable network structure, effectively hindering the bending deformation of the nanosheets. This work presents a promising structural design route for high-performance graphene-based nanomaterials and expands their potential applications.

Summary: The expression and function of the Arrb2 gene is increased in valproic acid-induced autistic mice models. However, the role of Arrb2 in the pathogenesis of autism spectrum disorder is not fully understood. This study found that Arrb2-/- mice have normal behavioral characteristics but reduced autophagy marker protein LC3B in the hippocampus. Deletion of Arrb2 leads to hyperactivation of the Akt-mTOR signaling pathway and abnormal mitochondrial dysfunction in hippocampal neurons.

Summary: Carbon nanotubes (CNTs) are considered the next-generation metamaterials with excellent mechanical properties. CNT fibers (CNFs), assembled by a large amount of CNTs, have promising mechanical properties and potential applications in various fields. In this study, coarse-grained molecular dynamic simulations are used to investigate the mechanical mechanisms of CNFs with different twisting degrees and CNT lengths. The results reveal that CNFs exhibit successive bearing capacity through bond stretching and bond fracture modes, and their mechanical properties can be efficiently tuned by adjusting the twisting degree. Defective CNFs with shorter CNTs show improved van der Waals interaction and enhanced stretchability after the transformation from curved to straight geometry. This work provides insights into the construction and optimization of super-strong CNFs.

Summary: It has been found that dispersing MXenes in a coral-like structure on the surface of a sponge, instead of participating in the assembly of the framework, effectively suppresses self-restacking of MXene, improves the sponge's hydrophilicity, and provides fast diffusion channels for electrolyte ions. Therefore, the MXene-TiC-reduced graphene oxide sponge exhibits excellent electrical conductivity, enormous specific surface area, and superior electrochemical performance as a Zinc-ion hybrid supercapacitor cathode. It surpasses most leading MXene-based Zn-ion cathodes and provides a new synthetic idea for MXene-based macro-composites and designing next-generation flexible and portable porous electrodes.
