Incorporating supplementary cementitious materials (SCMs) into ultra-high performance concrete (UHPC) is an effective approach to promote properties and reduce CO₂ emissions. Nevertheless, excessive utilization of SCMs can negatively impact mechanical performance. A deeper understanding synergistic effects of SCMs from micromechanics to dynamic behaviors could contribute to developing eco-friendly UHPC with enhanced impact resistance and lower environmental impact. Here, the hydration products, pore structures, micromechanics of interfacial transition zone (ITZ), dynamic properties and environmental impact of UHPC with binary, ternary and quaternary blends are evaluated. Results indicate that the synergistic effect of quaternary blends could optimize the bonding properties of ITZ between steel fibers and matrix as well as densify the microstructure by generation of higher percentage of ultra-high and high density C-S-H, thus enhancing the dynamic strength and impact resistance. The better micromechanics properties of ITZ delay the occurrence of initial cracks, resulting in the slightest damage degree under similar strain rate. More homogeneity of the microstructure of the matrix and better micromechanical properties of ITZ results in a lower dynamic increase factor (DIF). A predictive model of DIF for UHPC is established considering strain rates and the synergistic effect of SCMs. Finally, the environmental analysis reveals that the quaternary blends can significantly improve environmental friendliness by reducing carbon footprint.

To seek novel fluorescent materials, a series of three rare-earth-doped molybdate precursor glass (PG) and glass-ceramics (GCs) containing NaGd(MoO₄)₂ nanocrystals were achieved by high-temperature melting and subsequent controlled crystallization technique. The results reveal that adjustable color emission from blue to white region can be achieved in PG specimen with increasing contents of Eu³⁺ ions. At the optimal concentration of 1.4Tm³⁺/2.8Tb³⁺/0.8Eu³⁺, the PG exhibits the color coordinates of (0.3279, 0.3142) and correlated color temperature of 5737 K, and the obtained GC sample (GC720) after heat treatment at 720 °C shows the correlated color temperature of 6106 K and the color coordinates of (0.3138, 0.3173), which are closest to the standard white light. The fluorescence luminescence intensity of GC720 is significantly higher than that of PG. Decay curves and photoluminescence spectra verify the existence of energy conversion from Tb³⁺ and Tm³⁺ to Eu³⁺. Furthermore, the LED lamps encapsulated with GC720 and PG emit a bright white light and have a high color-rendering index of more than 86. These findings demonstrate that the developed 1.4Tm³⁺/2.8Tb³⁺/0.8Eu³⁺ doped PG and GC720 have tremendous potential in white LEDs.

This study introduces a LaCoO₃/MoS₂ heterojunction photocatalyst designed to effectively degrade organic contaminants in wastewater. The catalyst's performance was assessed by testing it against various synthetic dyes and real industrial wastewater under direct sunlight. A unique aspect of this research is the distinctive morphology of the nanocomposites, which resembles marine algae and extended flower structures. This morphology offers a high density of active sites for redox reactions, promoting a synergistic interaction between LaCoO₃ and MoS₂. As a result, there is enhanced charge separation and transfer efficiency, leading to superior photocatalytic performance. Various characterization techniques, including XRD, FE-SEM, XPS, FT-IR, UV–visible, PL spectroscopy, and Terephthalic Acid (TA) analysis, provide detailed insights into the structural, morphological, and chemical features that boost the photocatalytic activity of the Z-scheme LaCoO₃/MoS₂ heterojunction. The photocatalytic efficiency of the LaCoO₃/MoS₂ nanocomposites was evaluated by degrading synthetic dyes such as Methylene Blue (MB), Crystal Violet (CV), and Eriochrome Black T (EBT). The results show degradation efficiencies exceeding 95 % within 45 min under natural sunlight than pristine. Additionally, the nanocomposites exhibit remarkable degradation capabilities towards actual industrial dye effluents, achieving a degradation efficiency of 36 % within 60 min under sunlight irradiation. This underscores the rapid and effective degradation of organic pollutants in complex industrial wastewater, attributed to the simultaneous generation of superoxide and hydroxyl radicals through the Z-scheme heterojunction and efficient redox processes. The comprehensive characterization combined with the outstanding photocatalytic performance positions the LaCoO₃/MoS₂ heterojunction as a promising solution for sustainable water treatment applications. It addresses water pollution challenges and advances environmental remediation through innovative photocatalytic technologies.

Functionalizing and modification of high surface area activated carbon using metal-oxide nanoparticles have acquired a high interest due to improving inherent properties. The synthesis of morphology-tunned Cu₂O nanostructures such as the sphere, cube, truncated octahedron, and truncated cuboctahedrons-shaped Cu₂O is achieved via a co-precipitation method. The as-prepared Cu₂O is loaded on biomass waste chili pedicle activated carbon (CPAC). Cu₂O-loaded activated carbon (Cu₂O/CPAC) is synthesized by ultrasonication method. This article mainly focuses on the shape effect of Cu₂O and the support effect of heterogeneous catalysts for the Friedel–Crafts arylation of indoles and various aldehydes to provide bis(3-indolyl) methanes (BMI) derivative compounds. A rapid and efficient one-pot reaction was achieved under mild conditions using a green solvent, resulting in an active product with high TON, and TOF. The results of the study revealed that the catalytic activity order is tOh-Cu₂O > COh-Cu₂O > C-Cu₂O > S-Cu₂O. Notably, the 10 wt% tOh-Cu₂O/CPAC nanohybrid (1 mol% Cu(I), shows remarkable catalytic activity. The 10 wt% tOh-Cu₂O/CPAC catalyst is recycled at least five times for a specific reaction exhibiting a high yield of 95 % with a negligible loss of 3 % compared to the fresh catalyst's yield of 98 % showcasing its robust heterogeneity and sustainability.

Biosynthetic succinic acid and 1,4-butanediol (1,4-BDO) are attractive due to their high quality, low cost, and environmental sustainability, yet their yields are limited by weak strain activity and complex metabolic pathways. In this study, an anaerobic succinate synthesis pathway for was constructed in Escherichia coli ATCC 8739 via the reductive tricarboxylic acid (rTCA) cycle. Anaerobic fluorescence-activated droplet sorting (aFADS) and adaptive evolution technologies were developed to screen the strain mutants with enhanced succinate production capabilities. We further developed an enzymatic reaction to generate 1,4-BDO from succinate using a carboxylic acid and aldehyde reductase fused enzyme (CAR-AKR). To increase the yields of succinic acid and 1,4-BDO, we screened frdA and CAR-AKR mutants by NAD(P)H dependent high-throughput screening platforms, and found that the frdA^C248F mutant could significantly reduce the accumulation of fumarate, and the MabCAR^{L284W/S394I/W428M}-SceAKR mutant could strengthen the catalytic efficiency of conversion from succinate to 1,4-BDO. By strengthening the cofactors and ATP regeneration, the final yields of succinic acid and 1,4-BDO reached 85.74 g/L and 4.62 g/L in anaerobic fed-batch fermentation.

In this paper, reaction temperature-derived innovative nanostructures of ZnCo₂O₄ resemble the shape of urchin-like flowers when grown on 3D nickel foam using a straightforward binder-free hydrothermal method, followed by annealing treatment. These three-dimensional structures are composed of various nanosized petals interconnected on a spherical base, imitating the novel form of an urchin-like flower. This diverse arrangement improves the electrode's structural stability and electrochemical performance through its huge surface area and interconnected porous network. In conjunction with the binder-free design, the combined effects of ZnO and Co₃O₄ ions promote efficient charge transport and successfully modify electrochemistry. Notably, the optimized electrode displays a remarkable specific capacitance of 957.14 F/g (186.11 mAh/g) at a current density of 1 mA/cm² with prominent cycle stability. Moreover, the fabricated symmetric device of ZC120//ZC120 delivered 83.3 F/g (41.6 mAh/g) at 1 mA/cm² with 84.51 % cyclic stability over 10,000 GCD cycles at 30 mA/cm². Overall results suggested that temperature-dependent urchin-like flowers of ZnCo₂O₄ will be a good future choice for energy storage applications.

Cutting tools have long been essential across diverse fields, including mechanical processing, agriculture, biomedical applications, and geological exploration. However, traditional tool design faces limitations due to factors such as cutting environments and conditions. In response, bionic design—drawing inspiration from nature’s evolutionary solutions—has emerged as a transformative approach. Over billions of years, organisms have evolved unique characteristics, such as anti-adhesion, abrasion resistance, and self-sharpening, that can be applied to enhance cutting tool performance. However, the underlying logic and coupled design principles of interdisciplinary and cross-field bionic tool designs are crucial for the optimization of tool bionics, yet have not been systematically studied.

The rapid growth of additive manufacturing has been instrumental in advancing science and technology. Material Extrusion (ME) 3D Printing is a widely used additive manufacturing process, offering satisfactory results through parameter optimization. This process, known for its cost-effectiveness and ability to produce complex geometries, is widely used across various industries, from automotive to biomedical applications. In this study, we focus on analyzing key ME 3D printing parameters. Polylactic acid (PLA) is an ideal choice for 3D printing due to its renewable nature, low melting point, and minimal carbon footprint, ensuring stable and predictable mechanical properties for industrial and medical parts. PLA's biodegradability and availability as a filament make it a popular choice in the additive manufacturing industry. Our goal is to establish correlations between material characteristics, mechanical properties, and printing parameters using PLA as the base polymer through ANOVA analysis. The results show that optimized parameters, including a printing temperature of 220 °C and specific post-processing conditions, yield impressive outcomes. The ME 3D Printing machine achieved a 98 %-dimensional accuracy and enhanced strength, with PLA exhibiting a tensile strength of 38.9 MPa, which further increased to 55.9 MPa during post-processing (heating at 60 °C). Additionally, we provide a detailed mechanical and morphological properties comparison between ME 3D printed and injection molded samples. Life cycle assessment (LCA) analysis of optimized 3D printed PLA was compared with its injection-molded counterpart to evaluate their environmental sustainability and identify potential areas for improvement in manufacturing processes and resource utilization. Furthermore, we emphasize the importance of standardized terminology in the ME 3D Printing process.

Petroleum-based plastic foam is the most widely used cushioning material in the packaging and transporting of electronic products. However, its non-degradability and difficulty in recycling lead to serious environment burdens as large quantities are piled up and incinerated after use. Lignocellulosic foam with its natural, biodegradable and recyclable attributes has been introduced as an alternative product for petroleum-based foam. However, low mechanical strength, high insulation, and flammability of lignocellulosic foam limit their application in electronic products. In this study, porous and low-density carbon fiber lignocellulosic foams (CNF-APP-CFs) were synthesized by a mixture of nanocellulose, ammonium polyphosphate, carbon fiber, and lignocellulosic compounds at different ratio. The resulting foams had excellent mechanical properties, flame retardancy, and antistatic strain behavior, with the most substantial improvements observed in the foam containing 7 % carbon fiber which increased mechanical properties by 81.6 % and enhanced flame retardancy by 13.09 %. This work provides a feasible solution to mitigate the environmental hazards of petroleum-based plastic foams.
