In this study, Co-Fe-ZnS nanocomposites were synthesized from the plant extract of <em>Avena fatua</em> for enhanced photocatalytic degradation of Amoxicillin, hydrogen production, and CO₂ reduction, evaluated using Response Surface Methodology (RSM). The prepared nanocomposites were characterized by several customary analytical techniques, such as zeta potential, X-ray diffraction, Scanning electron microscopy, Transmission electron microscopy, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. After the analyses, prepared nanocomposites were evaluated against the photodegradation of Amoxicillin (AMX). The optimization of reaction parameters was performed by employing RSM. The optimized reaction values were found to be “pH = 11.99, AMX dose = 55.00 mg/L, Co-Fe-ZnS dose = 100.00 mg, time = 34.29 min, and temperature = 20.00 °C with the PD value of 88.96 %”. After that, the evaluation of photocatalytic hydrogen production and CO₂ conversion was executed. The synthesized photocomposites fostered an exceptional value of hydrogen (107.82 mmol g⁻¹ h⁻¹), 6 times higher than the pristine (18.59 mmol g⁻¹ h⁻¹). Moreover, the synthesized nanocomposites displayed a remarkable CO₂ reduction (49.48 μmolg⁻¹ h⁻¹) compared to the pristine (4.97 μmolg⁻¹ h⁻¹). The recyclability tests demonstrated that the photocatalyst retained 79.38 % of its degradation efficiency after five cycles, highlighting its practical reusability. Additionally, the role of reactive oxygen species (ROS) in the photocatalytic process was elucidated, with photogenerated holes (h⁺) identified as the primary contributors to AMX degradation.

In this study, shield soil dreg waste is recycled and activated to substitute cement in ultra-high performance concrete, aiming to promote solid waste management and sustainable construction. The slump, mechanical performance, and autogenous shrinkage of the concrete are investigated through macro-scale tests, and the underlying mechanism is revealed via micro-scale experiments. The incorporation of calcined shield soil dreg reduces flowability and leads to a 10.2 % deterioration in compressive strength of the ultra-high performance concrete while mitigating autogenous shrinkage. The primary reason is due to the low CaO content of shield soil dreg, which limits the formation of calcium silicate hydrate, and its high SiO₂/Al₂O₃ content slows hydration kinetics. The environmental and economic benefits of the concrete are determined via life cycle analysis. Recycling shield soil dreg waste into concrete results in about 35 % reduction in carbon emission and 22 % reduction in energy consumption. According to multi-criteria assessment, the overall performance of the concrete considering economic cost, environmental benefit, as well as physical and mechanical properties increases compared to the pristine concrete, achieving well-balanced economic feasibility, environmental sustainability, and engineering performance.

Disappointingly, oxidation always enriches high polarity poor-capacitance O-C=O groups (i.e., carboxyl/lactone) on the carbon material surface, which act as a double-edged sword for biochar's application in organic pollutant adsorption and electrochemical energy storage. Herein, microwave-induced air oxidation shock (MW-AOS) is proposed as a rapid and simple strategy to selectively oxygenate the surface of activated biochar (AB). Characterization results show that the surface of the pristine AB is remarkably oxygenated from 3.8 % to 11.8 % after MW-AOS at an output power of 800 W for 15 s. Interestingly, surface oxygenation is achieved while reducing the high-polarity poor-pseudocapacitance O-C=O groups (i.e., carboxyl/lactone) is selectively achieved at a shorter irradiation time (15 s). Batch adsorption results indicate that MW-AOS remarkably increases the adsorption of various organic pollutants (dyes and antibiotics) by AB. Electrochemical analysis reveals that the specific capacitance of the AB is improved by 250 % (from 60 to 208 F/g at 1 A/g after AOS at 800 W for 15 s), attributed to reduced electrical resistance and enhanced ion transport.

This study focuses on developing novel stainless steel welding electrodes using a flux-modified mild steel core wire. The primary objective is to achieve stainless steel-like mechanical properties while minimizing the release of hazardous emissions such as hexavalent chromium, ozone, and ultraviolet radiation. These newly developed electrodes are designed to provide the strength and corrosion resistance of stainless steel grades 304 and 316 without requiring modifications to conventional manufacturing processes, making them highly suitable for industrial applications, including structural fabrication, automotive components, and marine engineering. A novel flux composition incorporating nano-sized calcium carbonate and calcium titanate was formulated to enhance arc stability, reduce spatter, and improve alloying efficiency. Mechanical testing demonstrated significant improvements in tensile properties, with the ultimate tensile strength increasing to 544 MPa for the stainless steel 304 electrode and 560 MPa for the stainless steel 316 electrode. The yield tensile strength increased to 230 MPa and 285 MPa, respectively, reflecting enhanced resistance to deformation. Bending strength improved to approximately 460 MPa for the stainless steel 304 electrode and 490 MPa for the stainless steel 316 electrode, while microhardness values increased to 240 Vickers hardness number (VHN) and 250 VHN, respectively. Microstructural analysis revealed a refined weld structure with increased acicular ferrite content, leading to enhanced weld integrity and strength. In addition, the optimized flux formulation effectively reduced the release of toxic emissions, with hexavalent chromium concentrations decreasing by 32.7 % for stainless steel 304 electrodes and 22.7 % for stainless steel 316 electrodes. These results demonstrate that the newly developed electrodes provide a balanced combination of mechanical performance and environmental sustainability. The novel approach not only enhances the efficiency of stainless steel welding but also significantly reduces health risks for welders. The findings contribute to the advancement of cleaner welding technologies, offering a cost-effective and sustainable alternative for various industrial applications.</div></div>","PeriodicalId":22097,"journal":{"name":"Sustainable Materials and Technologies","volume":"44 ","pages":"Article e01372"},"PeriodicalIF":8.6,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143726276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
