In-situ hydrothermal deposition of 2D CuS/Cu<sub>9</sub>S<sub>5</sub> nanostructures on nickel foam at different pH was studied. The X-ray diffraction analysis confirmed two different stoichiometric forms, namely CuS and Cu<sub>9</sub>S<sub>5</sub>, in different proportions with a change in the synthesis pH. Morphological and compositional analysis exhibited a strong impact of pH on the CuS/Cu<sub>9</sub>S<sub>5</sub> deposits. The samples prepared at pH 6.5 presented less agglomerated and densely distributed 2D nanosheets. Transmission electron microscopic studies under high resolution for the deposits synthesized at pH 6.5 showed hexagonal CuS and rhombohedral Cu<sub>9</sub>S<sub>5</sub> particles of 32 nm average particle size. The electrochemical characterization of the samples for energy storage devices by cyclic voltammetry (CV) study revealed the specific capacitance from 1781 Fg<sup>−1</sup> to 1589 Fg<sup>−1</sup> at 10 mVs<sup>−1</sup>. The findings of CV and galvanostatic charge/discharge (GCD) analysis matched well. Rate capability studies showed the values between 72.9% and 50.24% at 7.5 Ag<sup>−1</sup> for various samples. The sample prepared at pH 6.5 exhibited 73.07% of its starting capacitance at 10 Ag<sup>−1</sup> after 2500 charging and discharging sequences. Electrochemical impedance spectroscopy runs (EIS) showed the existence of two constant phase elements (CPE) in series and the relaxation time constants from 0.01 to 0.5 seconds, which are preferred for energy storing purposes. Symmetric supercapacitor device prepared from sample deposited at pH 6.5 displayed 29.16 Wh energy per kg of material and a power density of 900 W kg<sup>−1</sup>, highlighting its suitability for high-efficiency energy storage applications.</div></div>","PeriodicalId":101081,"journal":{"name":"Resources Chemicals and Materials","volume":"4 3","pages":"Article 100119"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144231661","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}

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.

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.

While various gasifiers have been commercialized for fuel gas production, mitigating tar formation in gasifiers remains challenging. This review is devoted to summarizing the general strategies adopted in various gasifiers to reduce tar formation for high-efficiency clean gasification. For single-bed and staged-gasification processes, their low-tar strategies are typically different. In the single-bed processes, the low-tar strategies involve in-bed intensification achieved by controlling flow directions of gas and particles inside the gasifier. During the gasification, these two components often have different temperatures to facilitate thermochemical interactions between them. Meanwhile, the two-stage gasifiers are generally designed to decouple pyrolysis, gasification and tar cracking reactions for maximizing the benefits (such as yield and efficiency) realized from the interactions among these reactions. In addition to minimizing tar formation, the approach of reaction decoupling can also raise the calorific value of product gas, even without use of oxygen, and/or improve the adaptability of gasification technology to the feedstocks with various moisture contents and particle sizes. The reanalysis based on those essential low-tar strategies is expected to gain alternative insights into the reaction principles implicated in most advanced biomass gasification technologies.</div></div>","PeriodicalId":101081,"journal":{"name":"Resources Chemicals and Materials","volume":"4 2","pages":"Article 100087"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144713517","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}
