    estuary it appeared sporadically a kind of iron oxide rather uncommon in a weathering steel rust layer: akaganeite (β-FeO(OH), Figure 4, Raman bands at 312 and 391 cm-1). This iron oxide appears in seaside environments with high amount of NaCl air-borne [3]. Thus, akaganeite is often observed as a corrosion .

    ABSTRACT: Zinc oxide and organic polymer (poly-ethylene oxide) based nanocomposite membranes were prepared and their phase relationship investigated. The composites were characterized by XRD, Raman scattering, DSC, and impedance spectroscopy analysis. It was found that embedding inorganic nanoparticles of ZnO into the polymer matrix of PEO allowed for some crystallinity formation, and .

    In the world of pigments and art history, the term "ochre" generally refers to iron oxide and oxide hydroxide rich powders with variable amounts of manganese oxides (Eastaugh et al. and references therein). Red ochres are dominated by hematite and yellow ochres are typically dominated by goethite, though jarosite group mineral-rich yellow ochres are of local importance.

    Apr 01, 2010· Micro-Raman spectrometry. In the case of varnishes from three Stradivari instruments, neither in situ EDXRF nor scanning electron ­microscopy/EDX spectroscopy (SEM/EDX) on micro-samples were able to precisely answer the nature of the two types of red pigments observed. EDX spot analyses of specific grains showed that the first type was Fe-rich, possibly indicating an iron oxide.
