Summary: This study investigated the effects of adding PE fibers and AE on the rheological-strength-ductility properties of self-cleaning geopolymer composites as well as the geopolymerization reaction mechanisms. PE fibers dramatically improve ductility, while the strength first increases and then decreases with increasing AE content. The study proposes a microscopic model illustrating the tailoring mechanism of self-cleaning geopolymer composites through AE addition, showing a prospective application in road engineering.

Summary: Polyethylene (PE), a popular thermoplastic polymer, is widely used in materials and biomedical engineering. 3D printing via fused deposition modeling (FDM) provides an easy method for preparing PE products. We investigated the effects of printing parameters and degradation on the mechanical performance of FDM-printed PE fibers. Smaller diameter fibers prepared at higher collecting speeds exhibited higher tensile strength and Young's modulus. Higher printer head temperatures led to lower viscosity and weaker shearing, resulting in decreased tensile strength and Young's modulus. Degradation, such as UV exposure and thermal degradation, caused a decrease in all four mechanical properties. These findings will aid in optimizing FDM-printed PE materials and assessing their durability against degradation for practical applications.

Summary: In this study, PET composites reinforced with areca sheath and Moringa oleifera fruit fibers were fabricated using injection molding technique. Comparative analysis of the physical and mechanical properties of the different composite samples was conducted, including void percentage, micro-hardness, impact, flexural and tensile strength. SEM and TGA were used to analyze the surface texture and thermal properties. The results revealed that the MF composites had higher tensile and flexural properties, while the AM composites showed better micro-hardness and impact strength. SEM micrographs showcased improved fiber-matrix bonding in MF composites, indicating enhanced thermal degradation resistance. Consequently, these fiber-reinforced PET composites can be potentially utilized as alternative materials for lightly to moderately loaded structural engineering applications.

Summary: In this study, the tensile behavior of a flexible epoxy resin reinforced with knitted reinforcements from various fiber materials was comprehensively investigated. The results showed that the knitted structure had a significant impact on the deformation behavior of the flexible composites, with high local strain differences observed in the course direction. In the wale direction, the knitted structure led to plastic deformation of the matrix material. Yarns from recycled thermoplastic fibers exhibited higher maximum stress and strain at break compared to bio-based fibers, but irreversible damage occurred for all fiber materials at similar strain values.

Summary: Lignocellulose utilization is gaining attention worldwide due to its abundance and renewability. Biological pretreatment, with its mild reaction conditions and environmentally friendly characteristics, effectively targets the complex structures within lignocellulose. This comprehensive review analyzes the hierarchical structure of cell wall and the cross-linked network between cellulose, hemicellulose, and lignin. It highlights β-aryl ether cracking as a key process for lignin degradation. The review explores the impact of biological pretreatments, such as fungi, bacteria, microbial consortium, and enzymes, on substrate structure and degradation efficiency. Combining biological pretreatment with other methods can reduce the process time and enhance lignocellulose dissociation efficiency. The review also summarizes the various applications of lignocellulose, such as fuel production and chemicals platform, which can alleviate energy pressure through bioconversion. Future research should focus on genetic engineering and other technologies to improve biotransformation efficiency.

Summary: With the rapid development of the digital economy, promoting green innovation through digitalization has become crucial for manufacturing enterprises to enhance their core competitiveness. However, previous studies have primarily focused on enterprise green technology innovation rather than green innovation, and empirical tests mainly used regional-level data instead of enterprise-level data. This paper empirically investigates the impact and mechanism of digitalization on green innovation in Chinese manufacturing enterprises from 2013-2019. The findings indicate that digitalization significantly promotes the level of green innovation in manufacturing enterprises and exerts a greater influence on labor-intensive industries and manufacturing enterprises in central China compared to capital- or technology-intensive industries and enterprises in eastern China. Additionally, digitalization can influence green innovation in manufacturing enterprises through three intermediary channels: promoting enterprise value chain upgrading, empowering industrial structure optimization, and enhancing technological innovation.

Summary: The conversion of lignocellulosic biomass to liquid substances through liquefaction was considered promising for their high-value utilization. The reaction of degradation and polycondensation in the liquefaction process directly affected the product's characteristics. The liquefaction of Chinese Sweet Gum's fruit was performed at various times, and the results showed that the efficiency increased with longer reaction time and the optimal time was 120 min. FTIR and XRD analysis revealed the prioritized degradation of lignin and hemicellulose at the initial stage of liquefaction. The study also explored the feasibility of using liquefaction products in polyurethane foam, showing that they could replace polyols without changing the foam's chemical structure.
