Galvanostatic measurement tests of above three levelers were conducted to find out that Aza exhibited the largest adsorption strength on the surface of copper. The adsorption of Aza was strongly related to convection intensity, particularly when concentration of Aza in the plating bath reached &gt;7.2 μmol/L. Molecular dynamics simulations were carried out to gain insights into the adsorption behavior of Aza, IMI and Merc, and results revealed that when Aza adsorbed on the copper surface, the imidazole part of Aza played a significant role. This finding was consistent with quantum chemical calculations, which indicated that the lowest unoccupied molecular orbital (LUMO) of Aza was predominantly localized on the imidazole moiety, underscoring its importance in the electron transfer process. Electroplating tests were then performed and the throwing power (TP) of through-holes with aspect ratio of 10:1 reached 106 % with Aza-based formula, compared to the TP of 26.9 % obtained from leveler-free formula. Physical properties of copper deposits, including surface morphology, roughness, and structure orientation, indicated that Aza could decrease roughness of electroplating copper and promote growth along the Cu(111) orientation. In this way, Aza has been proven to be a more effective leveler in through-hole plating than its local-structure molecules of IMI and Merc.</p></div>","PeriodicalId":22081,"journal":{"name":"Surfaces and Interfaces","volume":null,"pages":null},"PeriodicalIF":5.7,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142173005","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}

The high cORRelation between the coordination descriptor <em>φ</em> and the Δ<em>G</em>_O* value of the catalysts also further confirms the accuracy of our use of the Δ<em>G</em>_O* value as a screening criterion.

The corrosion behavior of NC<img>Ni with varying grain sizes of 20 nm, 100 nm and 200 nm in a FLiNaK environment is studied. Interestingly, as the grain size increases, there is a systematic increase in weight loss. Studies conducted using electron backscattered diffraction (EBSD) on corrosion-tested and annealed samples revealed the significant role played by various microstructural attributes in enhancing corrosion resistance. These attributes include 〈100〉 crystallographic orientation, a high fraction of twin boundaries, low random boundary connectivity, high J₂/(1-J₃) value and low grain boundary length per area. The NC<img>Ni with the 20 nm grain size showed exceptional corrosion resistance due to a higher prevalence of these attributes. Furthermore, corrosion-induced facets, such as pyramids, terraces, steps, etc., are observed for the first time in FLiNaK solution, with grain interiors and boundaries exhibiting various morphologies. The impurities from the salt result in surface anisotropy leading to surface reconstruction and formation of facets. The study presents new findings that are significant for the MSR community: in systems where the protective oxide layer dissolves readily and lacks sustainability in the corroding medium, all the above-mentioned microstructural attributes are vital.

The structural confirmation through XRD and FTIR confirmed the successful formation of pristine g-C₃N₄, BFWO NPs, and their composites. FESEM micrographs revealed multilayered sheet-like formation for C₃N₄ whereas irregular cuboid-shaped structure for BFWO NPs. In the composite formation, the sheets tended to appear wrapped around the BFWO NPs. The UV-DRS absorbance spectra exhibited a highlighted increase in the absorbance region towards the visible light region following a decrease in the band gap. The photoluminescence lifetime studies revealed an enhanced lifetime of excitons to 6.21 ns for 50:50 (g-C₃N₄: BFWO) composite formation, whereas pristine g-CN displayed an average lifetime of about 4.79 ns. The degradation efficacy in the removal of RhB and MB from water revealed up to 100% and 95.5% removal rates in under 90 mins and 180 mins respectively using the 50:50 composite formation.

Comprehensive characterization techniques confirmed the formation of a mesoporous Zr(MoO₄)₂ structure with smooth surface morphology in the β-CD coated nanocomposites. The gas sensing performance of the synthesized nanocomposites was rigorously evaluated, with results indicating significantly improved activity towards VOCs at room temperature (30 °C).

This enhanced performance is attributed to the increased specific surface area, the porous structure of the composite, and the unique interaction between acetone and the active sites on the nanocomposite. Comparative analysis with literature-reported materials highlights the superior room-temperature performance of the 10βMZ nanocomposite, positioning it as a promising material for VOC detection in environmental monitoring and industrial safety.

X-ray diffraction results revealed that the crystallinity of MoS₂ thin films improved with increasing UVO exposure time, but long-term exposure (&gt; 5 min) decreased crystallinity due to surface etching.
