Several pretreatments were tested, including mechanical grinding, alkaline etching, and acid desmutting, and combinations therein. Zr-based conversion coatings were deposited on aluminum (AA2024-T3) from a solution of 0.01 M Zr4+. The corrosion behavior of the pre-treated and coated alloys was examined using potentiodynamic polarization in sodium chloride solution. The results showed that acid desmutting in nitric acid can cause localized corrosion in the form of selective magnesium dealloying and alkaline trenching around the S-Al2CuMg particles that continued during deposition and can compromise the corrosion protection. Alkaline etching in a sodium hydroxide solution resulted in removal of some of the larger intermetallic particles and increased the deposition rate but resulted in a cracked coating with inadequate adhesion. Desmutting in weak acid did not cause any trenching during the pretreatment and deposition. However, uneven and cracked deposition of the coating on intermetallic particles compromised the corrosion protection. These results show the benefits and limitations of common pretreatments and can lead to the development of improved pretreatment procedures and corrosion protection.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"55 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143653725","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}

We report a carbon supported bimetallic alloy nanocatalyst by dispersing CoNi alloy nanoparticles on the surface of nitrogen-doped mesoporous hollow carbon nanospheres (CoNi/N-MHCS).

The catalyst also demonstrates an excellent electro-Fenton performance in degrading tetracycline hydrochloride (TCH) as a demonstration of its on-site practicability. Experiments and DFT theoretical calculations demonstrate that the charge redistribution between Co and Ni atoms due to the formation of CoNi alloy nanoparticles may reduce the reaction energy barrier of *OOH into H2O2, promote the reaction kinetics and modulate the adsorption energy of the intermediate *OOH on the CoNi active sites, thus enhancing the 2e- ORR electrocatalytic performance.

By contrast, Laser slicing SiC is an efficient way to produce SiC wafers with reduced material loss and improving productivity. The key of laser slicing technology is the generation, propagation and connection of cracks. In this paper, the influence of the process parameters of laser-slicing N-type 4H-SiC with nanosecond laser, including laser output power, scanning speed, scanning-lines numbers and group spacing, on the crack is studied in detail. Finally, a simple, fast and efficient multiple-line overlapping laser-scanning strategy has been developed for laser slicing of large-size 4H-SiC ingots. The optimal laser processing parameters are obtained to separate a 6 in. 4H-SiC wafer and the slicing time of ∼18 min per piece is much less than that of traditional multi-wire cutting. After polishing the sliced 4H-SiC wafer, its geometric parameters and stress state were investigated and showed that nanosecond laser slicing had no discernible impact on 4H-SiC. The above results present a promising route and demonstrate the feasibility of nanosecond laser for low-cost and high efficiency slicing of large-size 4H-SiC wafer.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"16 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143653729","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}

To alleviate this problem, photocatalytic degradation was proposed, and various catalysts have been developed with high efficiency and low cost. Herein, a novel 0D/3D/2D dual Z-heterojunction photocatalyst CdS QDs/Bi2WO6/g-C3N4 was constructed by in-situ growth method in order to efficiently degrade multiple antibiotic pollutants. The combination of multi-dimensional materials is more conducive to the close contact between materials and the effective transport of photogenerated carriers. Results reveal that the sample of 75 %CdS QDs/Bi2WO6/g-C3N4 (denoted as 0.75CSBC) showed the best degradation activity and stability for tetracycline (TC), and the degradation rate could reach 80.83 % within 12 min under visible light irradiation. Based on the detailed analysis of the results from free radical trapping experiment, Mott-Schottky test and liquid chromatography-mass spectrometry (LC-MS) test, the photocatalytic degradation mechanism and pathway were proposed. Besides, 0.75CSBC showed excellent degradation activity for levofloxacin (LVFX), oxytetracycline hydrochloride (OTC) and norfloxacin (NFLX), confirming its good universality. The multi-dimensional dual Z-heterojunction photocatalyst not only provides more active sites but also promotes the efficient migration of photogenerated charge, together with an excellent stability, indicating its wide practical application in the field of photocatalytic wastewater treatment.

Various methods were employed to evaluate the micromorphology, crystal structure, chemical composition, and optical characteristics of the photocatalysts. Supported by ultra-violet photoelectron spectroscopy (UPS) analyses, an S-scheme charge migration path was revealed in the CUS during the photocatalytic reaction. The CUS3:7 S-scheme heterojunction exhibited optimal photocatalytic activity at 4.08 times and 1.57 times higher than those of pure CuO and SM-300, respectively, and excellent photocatalytic activity was detected in the peroxymonosulfate (PMS) system.

In addition, the photocatalytic mechanism, possible intermediates, and degradation pathways were elucidated using theoretical calculations and experimental results.

In this study, we propose Li3P as a high-capacity pre-lithiation reagent for LIC anodes. Li3P was synthesized via a reaction between black phosphorus and molten lithium metal. Furthermore, a PTFE-binder-based dry-process method is developed for fabricating AC/Li3P composite cathodes. This method overcomes the issue of Li3P reactivity with conventional solvents typically used in wet coating processes and is fully compatible with the large-scale production of standard activated carbon (AC) electrodes. Li3P irreversibly decomposes during the first charging cycle, achieving an actual specific capacity of 1078 mAh/g and thereby supplying a significant amount of Li+. The LIC assembled with the Li3P/AC cathode demonstrates enhanced specific capacity and long-term cyclic stability.
