Reconciling the coordinate systems of the EBSD and AFM measurements is a challenging and time-consuming process for rough polycrystal surfaces. This paper presents a novel method for importing EBSD data into the AFM coordinate system with minimal user input. This method proceeds by simulating EBSD band contrast images from the AFM topography. Then, a mapping between this simulated and the measured EBSD band contrast image is established by least-squares fitting. With this mapping, the EBSD data are projected onto the AFM coordinate system. In addition to automatic facet type determination, this enables a statistical analysis of the relation between the orientation and surface morphology of individual crystals on polycrystal surfaces. As an application example we analyze etched copper surfaces that are obtained in intermediate steps of the production of printed circuit boards (PCBs).

The present review examines four different kinds of nanocomposites that have shown enormous potential in water splitting and dye degradation: those based on zinc, iron, titanium, and cerium. Zinc oxide's photocatalytic activity shifted from the ultraviolet to the visible spectrum when dopants were added or when it was mixed with other oxides, such as copper. When combined with substances like graphene, iron oxide—which is well-known for producing hydroxyl radicals—becomes very efficient at water splitting and dye degradation. Despite being limited by UV light, titanium dioxide performs better when paired with reduced graphene oxide or silver particles, which boosts its effectiveness in both processes when exposed to visible light. Lastly, cerium oxide's distinct redox characteristics enable it to create efficient heterojunctions with substances like ZnO and TiO₂, improving charge transfer and lowering recombination. Moreover, this review provides attention to their dual use and guides how to optimize photocatalytic efficiency for environmental remediation and sustainable energy generation.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 13","pages":"5721 - 5748"},"PeriodicalIF":3.5,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143783303","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}
