Summary: This paper correlates the rheological percolation threshold and hardness of Polypropylene/Sisal fibre composites. Power law fit was used to estimate the rheological percolation threshold. The effects of near-critical length fibre and short fibre on the thermomechanical, rheological, and dynamic mechanical properties of the composites were investigated. The results showed that sisal fibre significantly influenced the dynamic mechanical properties of the composites and the near-critical length fibre had properties equivalent to that of short fibre.

Summary: The dual interface-enhanced sizing agents were prepared using self-assembled nano-polymers to achieve high surface roughness and interfacial wettability. Five self-assembled nano-polymer modified water-based sizing agents (NPSAs) with different cross-linking structures were synthesized. NPSAs exhibited homogeneous particle size in the range of 90-200 nm and heat stability below 200 degrees C. The CF surface properties were significantly improved by NPSAs, with surface roughness and surface energy reaching high values of 13.89 nm and 40.22 mN m-1. The CF/ER composites sized by NPSAs showed enhanced interlaminar shear strength (ILSS), flexural strength, and fracture toughness (KIC) by 70%, 51%, and 120% compared to the unoptimized composite, respectively. The reinforcing mechanism of NPSAs was clarified through the coefficient of thermal expansion (CTE1), which improved the interfacial interlocking and adhesion ability of CF/ER composites. Additionally, NPSAs have the advantages of simple one-pot synthesis methods and no use of toxic solvents.

Summary: All-solid-state lithium-sulfur batteries (ASSLSBs) are highly desirable due to their high capacity, low cost, and environmental friendliness. This study focuses on the interfacial structure, electrical properties, and lithium-ion transport of the Li10SnP2S12 (LSPS)/Li interface in ASSLSBs. The research reveals the formation of an interface layer that blocks electron conduction, accelerates lithium-ion diffusion, and disrupts surface structures. Molecular dynamics simulations confirm the benefits of the interface on Li+ conduction. Additionally, the study highlights the rapid diffusion of sulfur and phosphorus into the Li anode, causing damage to its integrity and leading to decreased battery performance and safety concerns. This research provides theoretical guidance for the future application of LSPS in practical engineering.

Summary: The concept of chainmail catalyst, which encapsulates an active species within a carbon support, is well-established to ensure extraordinary stability for catalytic reactions in harsh conditions. However, conventional chainmail catalysts suffer from poor accessibility to active sites, resulting in the need for additional voltage to compensate for sluggish diffusion kinetics in electrocatalysis. In this study, cobalt nanoparticles were encapsulated within N-doped carbonized wood to create a monolithic chainmail electrocatalyst. The resulting catalyst exhibited excellent performance as an electrode for hydrogen evolution, oxygen evolution, and monosaccharide oxidation reactions.
