The study aimed to identify the mineral characterizations and distribution of lead, zinc, and carbon. X-ray fluorescence and chemical analysis showed lead, zinc, and carbon grades of 0.58%, 2.44%, and 5.33%, respectively. X-ray diffraction, polarizing microscopy, and mineral liberation analysis revealed lead and zinc mainly occur as galena and marmatite, with carbon as graphite. The particle sizes are small and symbiotic relationships complex. Additionally, the characteristic features of carbon-bearing lead–zinc ore were summarized, and the current plant flowsheet and outcomes were assessed. The improved flowsheet includes X-ray sorting before grinding and a flotation column in zinc flotation to treat the regrinding middling separately. This approach achieved a Pb grade of 65.34% with a recovery of 70.64% and a Zn grade of 45.61% with a recovery of 89.98%. The Sanguikou plant processes 5000 t/day, producing 23.58 t of lead concentrate and 105.41 t of zinc concentrate daily. The new flowsheet enhances the grade and recovery of lead and zinc concentrates. The proposed flowsheet is a promising comprehensive recovery method and cleaner production process for this unique lead–zinc resource.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 2","pages":"830 - 841"},"PeriodicalIF":2.1,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142994498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As such, the influence of sputtering power on the growth of titanium (Ti) thin films was studied. The Ti thin films were deposited using a direct current (DC) magnetron sputtering system from a pure Ti target on a glass substrate at varying sputtering powers of 15% (54.12 W), 30% (109.70 W), and 50% (188.17 W) of the maximum system capacity. The thin films were then characterised for topography using atomic force microscopy (AFM), morphology using a field emission scanning electron microscope (FESEM), and crystallinity using an x-ray diffractometer (XRD). Furthermore, fractal analysis based on the AFM imaging was undertaken to evaluate the growth mechanisms of the Ti thin films. The thickness, grain size, and roughness of the thin films increased with the deposition power. The samples were mostly amorphous, although at 30% and 50%, a weak peak of Ti (002) was observed via x-ray diffraction. The fractal dimension (Df) decreased with increasing power. The multifractality strength increased with increasing power. Based on the fractal study, Volmer-Weber and Stranski-Krastanov's modes describe the growth mechanism of Ti thin films deposited at varying sputtering power.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 2","pages":"564 - 577"},"PeriodicalIF":2.1,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11837-024-07012-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142994429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, an efficient two-step strategy was proposed for the fabrication of an rGO-supprted NiMoO<sub>4</sub> electrode as a pseudocapacitive electrode. In the first step, rGO nanosheets were deposited on nickel foam by a hydrothermal process to obtain a 3D porous scaffold. In the next step, worm-like nickel molybdate nanoparticles were grown on the rGO framework by a cathodic galvanostatic electrodeposition and subsequent calcination. The structure and morphology of the electrodes were characterized by x-ray diffraction and field-emission scanning electron microscopy. The results demonstrated that NiMoO<sub>4</sub> nanoworms were uniformly deposited on the surface of the rGO nanosheets, forming a 3D porous structure. Electrochemical characteristics of the electrodes were examined by cyclic voltammetry, galvanostatic charge-discharge and electrochemical impedance spectroscopy. According to the unique 3D structure, the hybrid electrode exhibited superior charge storage performance including a high specific capacitance of 1243 F g<sup>−1</sup> at 1 A g<sup>−1</sup>, excellent cycling stability (92.3% capacitance retention after 2000 cycles), and good rate capability (68.1% capacitance retention with a 10-fold increase in the current rate).</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 2","pages":"529 - 538"},"PeriodicalIF":2.1,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142994430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the stochastic distribution of Wiener and Weibull, a salt freeze-thaw damage model was developed with the relative dynamic elastic modulus (RDEM) and mass loss rate as degradation indexes to analyze the reliability and predict the service life of NS-PPF-ASC. The results showed that adding the appropriate PPF significantly reduced the damage caused by the SFTC. Based on Wiener and Weibull stochastic distributions, the salt freeze-thaw damage models established with RDEM and mass loss rate as degradation indexes effectively predicted the service life of concrete, and both indicated that specimens in S1-FD have the best frost resistance and mass loss rate as degradation index. The Wiener and Weibull stochastic distributions were close, and the Weibull stochastic distribution was more suitable for NS-PPF-ASC damage and deterioration during the SFTC. The research results could provide a theoretical basis for the research of frost resistance durability of concrete structures in the cold region of Northwest China.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 2","pages":"911 - 923"},"PeriodicalIF":2.1,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142995857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
