In this work, a Mg-Zn-Ca bio-magnesium alloy, with its surface being covered by a plasma electrolytic oxidation (PEO) coating and being further sealing post-treated by a phosphate chemical conversion coating (PCC), was immersed in the SBF. Surface morphology and composition were monitored and compared. Results showed that the EIS being directly fitted using ECs could offer valuable information for qualitative information.

In this study, we present a hybrid synthesis route for graphene electrodes that combines chemical vapor deposition (CVD) and microwave-assisted reduction, guided by machine learning (ML) optimization. A predictive neural network trained on over 100 synthesis experiments enabled precise tuning of key parameters, resulting in high conductivity (~ 9.6 × 105 S m<sup>−1</sup>). Raman analysis across ≥ 5 spots per sample showed hybrid graphene at ID/IG = 0.29 [mean ± SD to be reported], while the CVD control exhibited ID/IG ≈ 0.10 [mean ± SD]. These properties underpinned the electrodes’ high specific capacitance (up to 500 F g<sup>−1</sup>), energy density (120 Wh kg<sup>−1</sup>), and 95% retention over 10,000 cycles. The synthesized graphene was further hybridized with MnO<sub>2</sub>, RuO<sub>2</sub>, and conductive polymers (polyaniline, polypyrrole), leading to enhanced specific capacitance, energy density, and power density (70 kW kg<sup>−1</sup>), while maintaining long-term stability. Structural, thermal, and electrochemical evaluations confirmed the durability and high performance of the optimized electrodes. This work demonstrates a scalable and cost-effective graphene synthesis strategy for advanced energy storage, enabled by machine learning. The integration of data-driven optimization with roll-to-roll-compatible processing provides a promising pathway toward industrial deployment of graphene-based supercapacitors in transportation, grid systems, and flexible electronics.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 38","pages":"17738 - 17756"},"PeriodicalIF":3.9,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145143815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The addition of catalytic particulate material to electrodeposited nickel coatings enables the reduction of overpotentials for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), showing good catalytic activity in alkaline water splitting compared to the Ni–P matrix. For the NiFeOOH and NiFe-LDH coatings, low overpotentials of 278 and 249 mV at 10 mAcm<sup>−2</sup>, respectively, were obtained for OER. Meanwhile, for the CuB and FeB coatings, low overpotential values of 75 and 98 mV were obtained at − 10 mAcm<sup>−2</sup> for HER. The addition of catalytic particles promotes an increase in the electroactive area of the coatings, as well as the formation of metal oxides, hydroxides, and oxyhydroxides, which significantly enhances their catalytic activity.
