This can lead to severe ecological damage and persistent environmental issues, making it a significant concern for long-term sustainability. Thus, there is a strong need for high-performing adsorbents to remove high concentrations of Cr (VI) from the environment. In the present study, Citrus Limetta peels were utilised to produce pristine biochar, which was treated with iron oxides to generate magnetic biochar and modified with chitosan, sodium alginate, and pectin to produce respective modified biochar. Among all five biochars, Chitosan-modified biochar (CMBC) displayed the highest removal efficiency towards Cr (VI) from water with a maximum adsorption capacity of 152.44 mg/g and a removal capacity of 76.22 %. Furthermore, adsorption kinetics indicates that the adsorption process is a pseudo-second order-kinetic model with R² and q_e of 0.99 and 99 mg/g, respectively. The Langmuir isotherm best describes the adsorption process. After five regenerative cycles, the removal efficiency was maintained at up to 71.80 %.

This review systematically summarizes the design principles and recent advancements in both extrinsic and intrinsic self-healing polyurethane materials, highlighting their respective self-healing mechanisms and characteristics. For extrinsic system, damage repair is primarily achieved through microcapsules, hollow fibers, nanoparticles, and microvascular networks. However, their healing efficiency remains limited by the stability of carriers and the release kinetics of healing agents. In contrast, intrinsic self-healing polyurethane materials achieve self-healing through the reversibility of dynamic covalent and non-covalent bonds, which confer excellent self-healing capabilities while necessitating a precise balance between mechanical performance and self-healing efficiency. Moreover, their healing behavior is highly dependent on environmental conditions, potentially restricting their practical applications. Recent studies have demonstrated that the synergistic design of dynamic bonding networks can significantly enhance the mechanical properties, self-healing efficiency, and environmental adaptability.

In this study, anode-supported SOFC single cells were fabricated using a combination of slurry spraying and spin-coating technique to achieve a dense Yttria Stabilized Zirconia (YSZ) electrolyte layer while maintaining low production cost. The electrochemical performance of the fabricated SOFC was evaluated using hydrogen and dry methane as fuels. Microstructural analysis confirmed that the YSZ electrolyte exhibited high densification with a thickness of approximately 10 μm, ensuring excellent gas-tightness and preventing fuel crossover. The NiO-YSZ anode demonstrated favorable porosity, with well-sintered NiO particles forming a robust framework to facilitate electrochemical reactions. Performance evaluations revealed that under hydrogen operation, the SOFC achieved a peak power density of 1.408 W/cm² at 1000 °C, with open-circuit voltages (OCVs) closely matching theoretical predictions. When operated with dry methane, the SOFC maintained stable performance, reaching a peak power density of 0.96 W/cm² at 1000 °C, highlighting its potential for direct hydrocarbon utilization. Gas composition analysis of the anode exhaust confirmed the absence of excessive carbon deposition, indicating the effectiveness of the anode microstructure in mitigating coking during methane oxidation. These findings demonstrate that the spray-coated and spin-coated SOFC design offers a promising approach to improving fuel cell efficiency and cost-effectiveness.

However, tar generation during the gasification remains an issue, affecting operational efficiency and environmental health. Biochar has been confirmed as an inexpensive and efficient catalyst for tar removal. The challenge lies in creating a highly reactive biochar which can be applied for different types of biomass with varying properties. This review discusses the factors that affect biochar's reactivity as a catalyst for tar reforming. Additionally, incorporating biochar into a gasification scenario with raw biomass offers a practical solution by leveraging the synergistic behavior. However, this synergy could be either positive or negative: the positive synergy enhances tar removal while the negative synergy has the opposite effect. The numerous factors affecting the results of gasification are presented in this review. It is concluded that the positive synergistic effect resulted from the balance between the available reactants from biomass and biochar, the optimal gas flowrate and the active sites on the carbon surface. Understanding these interactions is crucial for optimizing biochar performance for tar removal. Ultimately, this research provides insights into biochar's role in biomass gasification and suggests improvements for future studies to enhance the feasibility of biomass gasification with the assistance of biochar.</div></div>","PeriodicalId":101081,"journal":{"name":"Resources Chemicals and Materials","volume":"4 3","pages":"Article 100115"},"PeriodicalIF":0.0,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143891380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, utilization of CO-rich or H₂-rich gas of strong reducibility as reducing agent for magnetization roasting would lead to over-reduction of Fe₂O₃ in the ore to non-magnetic FeO, which makes the magnetism of the roasted ore be lower than its maximum, and hence leads to a lower iron recovery than expected. To explore the possibility of using CH₄ as reducing agent for controllable reduction of Fe₂O₃ in iron ores to selectively forming magnetic Fe₃O₄, i.e., for maximizing the magnetism of the reduced ore for efficient iron separation and recovery, a series of fluidized bed reduction tests in CH₄ were carried out on two iron ores of 55 % and 33 % iron at different temperatures for different periods of time, and the resultant reduced ore particles were magnetically separated for recovery of iron concentrate. XRD and ICP analyses were performed on all recovered iron concentrates to identify the crystal forms of their iron species and to quantify their iron contents. The results have shown that the controllable reduction by CH₄ of Fe₂O₃ in the iron ores to strongly magnetic Fe₃O₄ can be realized by controlling the reduction temperature and time condition applied. The resultant concentrates can be fully recovered by magnetic separation in a weak magnetic field of 60 kA/m to attain a maximum iron recovery of 98 % for the high-grade ore and that of 65 % for the low-grade ore. Besides, the results have also shown that the most critical factor affecting the controllability of the ore reduction process and the selectivity to the generation of magnetic Fe₃O₄-containing particles is the reduction temperature, and that the upper temperature threshold for the controllable reduction and selective generation of strongly magnetic iron concentrate is about 650℃.</div></div>","PeriodicalId":101081,"journal":{"name":"Resources Chemicals and Materials","volume":"4 1","pages":"Article 100078"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141698256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
