The Anode Effect (AE) in primary aluminum production is a critical issue for the industry, contributing significantly to greenhouse gas emissions and current efficiency. This study investigates the role of the bubble layer and fluorocarbon (CFₓ) passivation film on a 50 cm² industrial carbon anode during AE initiation, using in-situ video observation in a high-temperature transparent electrolytic cell at 940 °C, combined with non-in situ X-ray photoelectron spectroscopy (XPS) and gas chromatography techniques. Additionally, it analyzes the reasons for gas changes before and after AE. Video observations combined with XPS analysis confirm that the bubble-free region formed during the electrolysis stage contains a complex high-resistance and insulating CF_x film, which is the root cause of AE. CF_x cannot continuously generate and cover the electrode surface, nor can it quickly trigger new AE again. The bubble layer covering the anode is a secondary phenomenon resulting from the deterioration of wettability caused by CF_x. CF_x plays a central role in impeding current flow, increasing cell voltage, and halting electrochemical activity in the affected areas. The composition of CF_x can be altered by AE, leading to variations in back electromotive force(BEMF). Gas chromatography detection confirms that even after AE, the partial CF_x film remains on the anode surface, where it forms a "memory effect" and decomposes at high temperatures to produce PFC. In industrial testing, the changes in anode gas composition before and after AE can be attributed to the CF_x film formed on the anode surface and its degree of fluorination. This study suggests that targeting CFₓ layer formation, rather than bubble layer dynamics, could be a more effective strategy for reducing AE frequency, enhancing energy efficiency, and minimizing emissions in aluminum smelting. These insights offer a refined understanding of AE mechanisms for improving the sustainability and stability of industrial aluminum production processes.

The rapid movement of electrons during electrical heating produces electromagnetic shielding phenomena (along with an increase in the dielectric constant), which severely hampers the transmission of electromagnetic waves. We propose a patterned structure based on an electrically heated film that enables efficient surface heating and high wave-transmittance. In this paper, the structure exhibits a transmittance greater than 50 % in the 2–18 GHz band and excellent transmittance exceeding 80 % in the 2–8.88 GHz band under vertically incident TM-polarized electromagnetic waves (parallel polarized or vertically polarized wave). The de-icing experiments demonstrated the excellent heating efficiency and fast electrothermal response time of the structure. At a loading power of 4629.6 W/m2, the surface temperature of the structure reached 50.6 °C after 110 s, resulting in the shedding of surface ice. This work proposes a coupling strategy between wave transparency and electro-thermal performance, which is important for promoting the development of integrated structures with stealth/de-icing capabilities.

Nowadays, interest in metal organic frameworks (MOFs) as potential materials for corrosion protection of aluminium alloys is increasing. However, application of MOFs in the form of conversion coatings remains limited due to challenging process of MOFs growth directly on Al based surfaces. This obstacle can be overcome by surface pretreatment that promotes further MOF formation. In the current investigation, Zn-Al LDH (layered double hydroxide) grown on the surface of AA2024 aluminium alloy was recrystallised into ZIF-8@Zn-Al LDH coating. In situ synchrotron and ex situ XRD analyses showed that recrystallisation of Zn-Al LDH into ZIF-8 was accompanied by intercalation of 2-methylimidazolate into the LDH gallery under the applied treatment conditions. Such a complex structure of the coating was beneficial for the corrosion protection of AA2024 alloy as the obtained coating contained an increased amount of 2-methylimidazole inhibitive species. Moreover, it was found that the variation of the treatment condition (95–140 °C, 3–24 h) affected the final performance of the ZIF-8@Zn-Al-LDH coating and the coating obtained at 95 °C for 12 h demonstrated the best performance.

Integration of flexible conductive electrodes and components is a critical technology for advancing smart wearable electronics. However, the intricate fabrication process, mechanical mismatch, and weak interface bonding for electronics integration often hinder its practical application. Here, we report a facile strategy that combing laser-induced graphene and electroless copper plating to integrate high-performance planar and curved flexible circuits for human physiological signals monitoring. The laser-induced copper patterns and porous graphene serve as flexible electrodes and functional components, respectively. As a result, the laser-induced patterned copper exhibits excellent electrical conductivity (0.037 Ω/sq), electrical stability (∼2 % variation over 30 days) and a high interface bonding strength at the 5B level. As a demonstration, the copper conductors and graphene components achieve seamless integration within planar and curved flexible substrates. The integrated prototype device demonstrates superior conformability, ensuring precise signal detection. This method sheds a new light on high-performance wearable devices in physiological signal monitoring.

Herein, for the first time, we present a facile one-pot hydrothermal approach to synthesize snowflake-like FeO(OH), with Na(C₆H₅COO) employed as the guiding agent. The as-synthesized FeO(OH) displays a distinctive snowflake-like morphology, which is constituted by a large number of nanorods radiating outward in a six-petaled pattern from a central vertex. In contrast, in the absence of Na(C₆H₅COO), only irregular Fe₂O₃ particles were obtained. The unique snowflake architecture endows FeO(OH) with more efficient electron/ion transport channels and a substantially enlarged specific surface area, thereby enhancing electron/ion mobility and affording abundant active sites. Consequently, when applied as anodes in lithium-ion batteries, the snowflake-like FeO(OH) exhibits an outstanding charge capacity of 1390 mAh g⁻¹ at a current density of 0.1 A g⁻¹ even after 200 cycles, and remarkable long-term cyclic stability up to 300 cycles at 1 A g⁻¹. Moreover, this snowflake-like FeO(OH) also manifests good photocatalytic activity in dye degradation. These findings unequivocally suggest that the snowflake-like FeO(OH) holds great promise for applications in both lithium-ion batteries and photocatalysis fields.

The practical progression of quantum-dot sensitized solar cells (QDSSCs) due to the poor stability, which directly related to the leakage and volatileness of liquid electrolyte. Herein, the sodium alginate (SA) polysulfide gel electrolyte prepared by grinding method was first applied in the quasi-solid state QDSSCs. It has a pore structure which can elevate the rapid diffusion of ions. And the cross-linked interface with photoanode is smooth and non-adherent. The SA polysulfide gel electrolyte was used in Zn-Cu-In-Se (ZCISe) QDSSCs for standard experiments. The QDSSCs are able to materialize the photoelectric conversion efficiency (PCE) of 8.85% (V_oc is 0.63 V, J_sc is 26.16 mA·cm⁻², FF is 51.80), which is 6% higher than the liquid polysulfide QDSSCs (8.34%). Above all, the stability is 3.2 times higher than that of liquid polysulfide electrolyte. The research fulfilled the goal of both efficiency and stability, also environmentally friendly.

Magnesium implants offer the advantages of biodegradability and absorbability after implantation in bone fractures. However, they cause delayed bone regeneration owing to their fast biodegradation rates.

To address this issue, we attempted to utilize the bioactivity of bioceramic coatings and anti-corrosion property by doping Zn ions onto Mg implant surfaces. Zn-doped CaP bioceramic precipitation was induced on magnesium surfaces via electrochemical deposition in a mixed electrolyte of Ca(NO₃)₂ and NH₄H₂PO₄ with varying concentrations of Zn(NO₃)₂. As a result, in an electrolyte containing a low concentration of Zn(NO₃)₂, a uniform film layer, consisting of hydroxyapatite (HA) and calcium zinc phosphate hydrate (CZPD) bioceramics, was formed with approximately 30 μm of thickness. This layer improved the corrosion resistance of the Mg surface in simulated body fluids and promoted the formation of bioactive substrates. Higher concentrations of Zn(NO₃)₂ in the electrolyte led to an enhanced corrosion resistance with increasing Ca(OH)₂ precipitation. However, corrosion products were formed instead of bioactive substrates. Therefore, it was demonstrated that appropriate Zn(NO₃)₂ addition during electrochemical deposition induced stable osteoblast attachment and uniform formation of a new bone layer, delayed biodegradation with excellent corrosion resistance, and promoted bone regeneration through the formation of bioactive substrates during implantation.

Nickel foam (NF) has been broadly adopted as the current collector for supercapacitors due to its high porosity, unique three-dimensional (3D) network structure and good electrical conductivity. However, its small specific surface area resulted in a low loading of active materials. Thus, it is of great significance to modify NF to obtain a current collector with high specific surface area. Herein, a 3D NF@CNTs composite current collector was fabricated through in-situ growth of carbon nanotubes (CNTs) on NF by chemical vapor deposition (CVD) method, followed by the combination of MnMoO₄ nanoflowers with CNTs via a hydrothermal method, and MnMoO₄/NF@CNTs composite electrode was successfully obtained. The results indicated that the distinct design of 3D NF@CNTs composite current collector could offer an efficient mesoporous network, a high specific surface area and rapid electron and ion transfer channels, and accommodate more active sites for MnMoO₄ nanoflowers. Accordingly, the optimized MnMoO₄–130/NF@CNTs electrode achieved a superior areal capacitance of up to 5300 mF/cm² (1886.1 F/g) at 2 mA/cm², and maintained an outstanding rate capability of 79.7 % at 25 mA/cm². After 2000 charge/discharge cycles, MnMoO₄–130/NF@CNTs possessed a capacitance retention rate of 81.0 %. Besides, a symmetric supercapacitor (SSC) was eventually fabricated based on MnMoO₄–130/NF@CNTs electrodes, and it delivered a favorable energy density of 0.0197 mWh/cm² at a power density of 0.3 mW/cm², along with a superb cycling performance with the capacitance retention rate of 94.7 % after 2000 cycles. The above results demonstrated that the 3D NF@CNTs composite current collector achieved by the CVD process would be a good route to improve the effective specific surface area of NF and the loading of active materials for high-performance supercapacitors.

The results indicated that the distinct design of 3D NF@CNTs composite current collector could offer an efficient mesoporous network, a high specific surface area and rapid electron and ion transfer channels, and accommodate more active sites for MnMoO<sub>4</sub> nanoflowers. Accordingly, the optimized MnMoO<sub>4</sub>–130/NF@CNTs electrode achieved a superior areal capacitance of up to 5300 mF/cm<sup>2</sup> (1886.1 F/g) at 2 mA/cm<sup>2</sup>, and maintained an outstanding rate capability of 79.7 % at 25 mA/cm<sup>2</sup>. After 2000 charge/discharge cycles, MnMoO<sub>4</sub>–130/NF@CNTs possessed a capacitance retention rate of 81.0 %. Besides, a symmetric supercapacitor (SSC) was eventually fabricated based on MnMoO<sub>4</sub>–130/NF@CNTs electrodes, and it delivered a favorable energy density of 0.0197 mWh/cm<sup>2</sup> at a power density of 0.3 mW/cm<sup>2</sup>, along with a superb cycling performance with the capacitance retention rate of 94.7 % after 2000 cycles. The above results demonstrated that the 3D NF@CNTs composite current collector achieved by the CVD process would be a good route to improve the effective specific surface area of NF and the loading of active materials for high-performance supercapacitors.</div></div>","PeriodicalId":22081,"journal":{"name":"Surfaces and Interfaces","volume":"58 ","pages":"Article 105786"},"PeriodicalIF":5.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143101096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study employed the hydrothermal method to dope Mn into Sn₃O₄, which was then combined with g-C₃N₄ through calcination to prepare an II-type Mn-Sn₃O₄-x/CN composite photocatalyst. The impact of Mn-Sn₃O₄ loading on the photocatalytic performance was discussed. The synthesized composite catalysts exhibited remarkable hydrogen production performance under visible light, with Mn-Sn₃O₄-10/CN demonstrating the highest performance. Characterization techniques confirmed the successful preparation of the catalysts, and the light absorption capacity, charge separation and transport efficiency of Mn-Sn₃O₄-10/CN are significantly improved compared to catalysts with other ratios. This study developed a Mn-Sn₃O₄-x/CN composite catalyst with high stability and good hydrogen production rate. It provides further directions for the research of g-C₃N₄-based composite catalysts.
