However, its practical application is severely limited by the poor initial Coulombic efficiency, long-term cycling stability, and scale production difficulty. Here, we developed a sodium involved process for preparing low-cost polymer-based hard carbon microspheres (HCMSs) with controllable morphology and properties. First, phenolics were dissolved in water with the assistance of sodium hydroxide by forming a sodium salt solution, and PF microspheres with adjustable sodium contents and sizes were gathered by a spray drying method. Then, sodium elements were removed during the carbonization process, which led to HCMSs with low surface area, abundant defect sites, and controllable interlayer spacing. Benefiting from the sodium involved process, the HCMS-1400-40 sample exhibits a high reversible specific capacity of 326.1 mAh/g in SIBs and remarkable initial Coulombic efficiency of 91.8%. Besides, the HCMS-1400-40 sample demonstrates excellent stability at large current of 1 C and retained 95.7% of its initial capacity even after 6000 cycles.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"30 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, this paper took fluorinated methacrylate containing perfluorinated branched short chains as the main fluorinated monomer to obtain the polymer emulsions PFSA and their corresponding coating. Then, the emulsions were modified with silica sol to construct the PFSA4/SiO<sub>2</sub>-modified coating. The structures of the emulsion and the micelle state were characterized. The surface morphology, surface chemical composition, wetting performance, acid and alkali resistance, and self-cleaning performance of the constructed coating were studied. The results showed that PFSA had high hydrophobicity, with its water contact angle (WCA) value ranging from 95.2° to 119.3°. After modification with silica sol, the contact angle increased, being greater than 150°, with the highest reaching 158.4°, achieving a superhydrophobic state.

Coordination between Co and Y in the catalyst resulted in more CoO<sub><i>x</i></sub> and oxygen vacancies, which are vital factors for cleaving the C–O bond of the furan ring.

The evolution of the capture efficiency and pressure drop of fiber with triangular, oval, and diamond cross sections is also explored. The results show that the fiber with a triangular cross-section and a rotation angle of 60° exhibits a better filtration performance for capturing particles with a size of 2 μm in terms of quality factor. In addition, further analysis of triangular cross-section fiber arrangement with isotropic and anisotropic staggered multifiber model reveals that most of the particles are more easily captured by the first two rows of fibers. In addition, the 3D dendrite structure is gradually formed due to the adhesion between the particles, causing a clogging phenomenon in the filtration process. In general, the filter-feeding mechanism of tennis shrimp seta provides theoretical support and insights for the optimization of the fiber filter, offering potential applications in environment protection and industrial filtration.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"34 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mixed-integer linear programming (MILP) model aims to minimize total system cost with detailed spatiotemporal resolution to meet hydrogen demand in Great Britain. Uncertainty is considered in hydrogen demand, gas, and technology costs, as well as renewables and biomass availability. To address the resulting combinatorial complexity, scenarios are reduced using forward scenario reduction. Optimization results indicate that a combination of autothermal reforming and biomass gasification with carbon capture and storage (CCS) is the most cost-efficient strategy under uncertainty. A what-if analysis explores the impact of water electrolysis penetration on the production mix.
