The effects of the dual-doping combination of hBN and MWCNTs-OH on the microstructure, mechanical properties, tribological behavior, and corrosion resistance of Ni-B composite coatings were systematically investigated. By comparing four types of coatings, namely Ni-B, Ni-B/PBN, Ni-B/PBC (PBN + MWCNTs-OH), and Ni-B/PBPC (PBN + PMWCNTs-OH), the role of the modification strategy in enhancing the dispersion of reinforcing phases and the associated synergistic reinforcement mechanism was revealed. The results showed that polydopamine successfully coated the surfaces of hBN and MWCNTs-OH, significantly improving their dispersion stability in the plating bath. The Ni-B/PBPC coating exhibited a dense surface with uniform nodules, a homogeneous distribution of reinforcing phases, and a refined grain size of 9.4 nm. This coating achieved a microhardness of 967.5 HV, which was 49.2% higher than that of pure Ni-B. Under a load of 40 N, it exhibited a low friction coefficient of 0.274, and its wear volume was reduced by 67.4% compared with that of the Ni-B/PBN coating, demonstrating excellent mechanical and anti-wear properties. Meanwhile, in a 3.5 wt% NaCl solution, the Ni-B/PBPC coating exhibited the most positive corrosion potential (–0.292 V), the lowest corrosion current density (0.76 µA cm^− 2), and the highest charge transfer resistance (6.75 × 10⁴ Ω cm²), with corrosion resistance improved by 47.1% compared with that of the Ni-B/PBN coating. The synergistic interplay between the lubricating effect of PBN and the strengthening effect of PMWCNTs-OH, combined with the uniform dispersion of the reinforcing phases and effective filling of coating defects, collectively contributed to the comprehensive enhancement of the mechanical, anti-wear, and corrosion resistance of the coatings.</p></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"30 11","pages":"3879 - 3899"},"PeriodicalIF":3.1,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149125617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transmission electron microscopy is indispensable for resolving its local structure and chemistry, yet LLZTO is highly sensitive to electron irradiation, which may compromise the reliability of structural characterization. Here, we investigate electron-beam-induced damage in LLZTO during TEM/STEM characterization and establish practical low-dose imaging conditions. Energy-transfer and sputtering-threshold analyses indicate that Li/O sublattices are preferentially perturbed under common accelerating voltages, whereas thermal effects analysis indicates that beam heating alone cannot account for the observed degradation. SAED, HRTEM, HAADF-STEM, EFTEM, EDS, and EELS measurements show progressive fading of diffraction spots, decay of high-frequency lattice information, local amorphization, and changes in Li/O-related signals under increasing dose or dose rate. Based on these observations, we summarize dose-sensitive damage features and low-dose characterization windows for LLZTO.

This review summarizes recent progress in CNT synthesis from CO₂ electroreduction in molten carbonates and chloride-carbonate hybrid melts. The thermodynamic and kinetic basis of carbonate reduction is first discussed, including selectivity between carbon and CO formation, oxide-ion transport, and catalyst-related interfacial processes. The roles of anodes and cathodes are then examined, with emphasis on oxygen evolution, metal dissolution, catalyst supply, cathodic activation, CNT growth pathways, interfacial reconstruction, ion migration, redeposition, and electrode stability. These analyses indicate that CNT formation in molten salts is not a simple carbon electrodeposition process, but a dynamic interfacial growth process governed by electrolyte chemistry, electrode behavior, catalyst evolution, and mass transport. Separation and purification strategies are also reviewed. Finally, key challenges are highlighted, including unclear intermediates, insufficient understanding of CO₂ absorption-electrolysis coupling, limited evaluation criteria, and the need for integrated reactor operation, product purification, and electrolyte recycling.</p></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"30 11","pages":"3765 - 3788"},"PeriodicalIF":3.1,"publicationDate":"2026-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149125656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
