To address the limitations of current inorganic electrochromic film fabrication processes, this paper proposes a novel, simple, efficient, cost-effective, and environmentally friendly method for producing Prussian blue (PB) films assisted by black phosphorus. The PB films exhibited excellent electrochromic performance, with an optical modulation rate of 79.78 % at 745 nm, fast switching time and high coloring efficiency of 367.37 cm²C^-1. Importantly, the optical modulation ability remained at 98.4 % of its original value even after 10,000 cycles, surpassing the best reported record for PB films. Furthermore, TGA and GIWAXS confirmed that the PB films had lower structural water content and a polycrystalline structure, leading to a significant improvement in their electrochemical stability. DFT calculations further confirmed that the PB films exhibited a lower bandgap and larger electron transitions. Additionally, the large-area ESWs (100 × 70 cm²) were fabricated via a simple immersion process, demonstrating the economic, environmental, efficient, practical, and reliable nature of this approach in industrial-scale production. This research represents a milestone in improving the performance and industrial-scale production of ESWs, with significant implications for the development of electrochromic technologies.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"91 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143876238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigate the origin of improved water stability through thermal treatment in V₃(PET), a MOF containing hexatopic peripherally extended triptycene (H₆PET) ligands, which show promise for hydrogen storage. While V₃(PET) should be water-stable due to strong metal (hard acid, V³⁺)-ligand (hard base, carboxylate group) bonds, our experimental and theoretical findings reveal that the presence of dangling ligand—defects caused by metal-modulator (acetate) bonds— reduces its water stability. Our first-principles density functional theory (DFT) calculations show that the defect formation energy for V₃(PET) with dangling ligands (+1.96 eV) is significantly lower than that for V₃(PET) without them (+6.34 eV), making it more vulnerable to humidity. By removing acetate and restoring the original metal–ligand bonds, we significantly enhance the water stability of V₃(PET). Additionally, thermally treated V₃(PET) retains about 95 % of its hydrogen storage performance even after 7 days in 60 % relative humidity and maintains high mechanical stability over 200 hydrogen storage cycles.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"97 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143876223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduced magnetic biochar (MB) into AD systems with various ratios of corn straw and pig manure and further investigated its effects on methane production and microbial community structure during semi-continuous AD. The results indicated that the enhancement of methane production by MB application was highly affected by the C/N ratio of substrate. Particularly, MB application alleviated acid inhibition in the carbon-rich reactor, where an increased methane production by 14.0 % was obtained. As for the nitrogen-rich reactor, MB application mitigated the ammonia accumulation and promoted volatile fatty acids (VFAs) production as well as H₂S removal. The microbial community indicated that the MB promoted methanogenesis in the carbon-rich reactor by enhancing the hydrogenotrophic methanogenesis pathway, whereas the acetoclastic methanogenesis pathway dominated the nitrogen-rich reactor. The metabolic pathway involved in VFAs synthesis and methanogenesis were enhanced due to MB addition. Additionally, recovered MB was proved to retain rich dominant microbial communities for AD system. This study could provide comprehensive insights into the application of MB in long-term AD systems and offer guidance for the stable operation of biogas plants.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"6 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143876229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents a heterosynaptic MoSe₂ memtransistor with ultra-low operating voltage and high linearity/symmetry. This device incorporates heterogeneous ions into the MoSe₂ channel through gold-assisted exfoliation process, resulting in a substantial reduction in both turn-on voltage to 5 mV and power consumption to 10 fW. Additionally, the addition of gate electrode as an extra modulation terminal enhances the tunability of the device weight with greatly improved linearity and symmetry. The calculated asymmetric ratio of the weight modulation is as low as 0.058, approaching the theoretical limit of 0.

Optimally designing oxygen vacancies in electrocatalysts is a powerful strategy to improve electrocatalytic CO₂ reduction to formate through modulation of their electronic structure, thus resulting in accelerating CO₂ reduction kinetics. Nevertheless, achieving precise control over the concentration and distribution of surface oxygen vacancies in electrocatalysts has not been thoroughly investigated or clarified. In this work, a series of sulfur-doped In₂O₃ electrocatalysts (S-In₂O₃) with varying concentrations of oxygen vacancies were synthesized through a rational design to achieve highly efficient electrocatalytic CO₂ reduction to formate. Experimental results and density functional theory (DFT) calculations demonstrate that the synergistic effect of sulfur doping and oxygen vacancies can significantly enhance CO₂ activation, causing the overall density of states of S-In₂O₃ to shift toward lower energy levels, thereby facilitating the formation of *OOCH intermediates. The optimized S-In₂O₃ electrocatalyst achieved a maximum formate Faradaic efficiency (FE) of 97.1 % at −1.1 V vs RHE, while maintaining a FE of over 90 % throughout 50-h stability test. Further investigation revealed the intrinsic relationship among sulfur doping, oxygen vacancy concentration, and CO₂RR performance.

In this study, a novel distributed reference electrode integrated into the battery separator was developed to overcome these limitations. The proposed design utilizes a multi-layer annular design with a sandwich structure, featuring hierarchical porosity to minimize the blocking effect and ensure accurate potential measurements across different regions of the battery. A thorough experimental characterization and analysis were conducted to validate the performance of this design. The results demonstrate that it offers superior spatial resolution and successfully captures localized anode potential variations, which are crucial for early-stage detection of localized lithium plating.

Strontium tungsten oxide (SrWO₄) microstructures exhibit promising biomedical applications, including bone tissue engineering and anticancer properties, due to their osteogenic and photocatalytic effects. However, its antifungal and antibiofilm activities remain unexplored. SrWO₄ was chosen for this study for its ability to generate reactive oxygen species (ROS) and its structural similarity to antimicrobial metal oxides. In this study, SrWO₄ microstructures were synthesized using sonication, hydrothermal, and stirring methods. Notably, ultrasonicated SrWO₄ (SO-SrWO₄) showed potent antifungal and antibiofilm activity at 150 µg/ml, achieving tenfold biofilm inhibition, whereas its precursors (Na₂WO₄ and SrCl₂) required 1,000 µg/ml for similar effects. This enhanced efficacy is due to combined physicochemical properties of precursors and elevated ROS generation. SO-SrWO₄ inhibited biofilm formation in multiple drug-resistant pathogens, including <em>Candida albicans</em>, <em>Staphylococcus aureus</em>, and uropathogenic <em>Escherichia coli</em>. Mechanistic analyses revealed significant impairment of filamentous growth in <em>C. albicans</em>, accompanied by downregulation of biofilm and hyphae-related genes and enhanced ROS-mediated oxidative stress. Importantly, SO-SrWO₄ compared to various other nanoparticles demonstrated minimal toxicity against human HepG2 liver cells with an IC₅₀ greater than 1,600 µg/ml, <em>Caenorhabditis elegans</em> survival, and <em>Brassica rapa</em> growth. This study highlights the potential of SrWO₄ microstructures as an effective, and non-cytotoxic broad-spectrum antimicrobial agent, which is the first study to report on these properties.
