We have studied by optical microscopy and SEM-EDX lapis lazuli particles adhering to a sample of the Turin Shroud. A total number seventy (and sub-particles) were found on surface this sample, characterized in details: they are little (of between 0.1 15 μm maximal length), blue colour, with spectrum chemical elements identical that Lazuli mineral. hypothetise these residues painting layers cove...

Here we present the first successful attempt to programme the surface properties of nanostructured soft biological tissues by atomic layer deposition (ALD). The nanopatterned surface of lotus leaf was tuned by 3-125 nm TiO2 thin films. The lotus/TiO2 composites were studied by SEM-EDX, XPS, Raman, TG-DTA, XRR, water contact angle and photocatalysis measurements. While we could preserve the supe...

The paper aims on the investigations of corrosion processes of three different porcelain fused to metal dental crowns with CoCrMo frameworks. The three crowns, with different exposed metal surfaces, were investigated using electrochemical impedance spectroscopy (EIS), through 168 hours of experiment. The data were analyzed and the influence of corrosion processes was shown after the crowns were...

Gold Mosaic glass has been used to decorate items and places since ancient time. The glass structure is divided into three layers: cover glass, gold layer and glass substrate. In this study, the composition of old-styled Thai gold mosaic glass samples was analyzed using SEM/EDX and Raman spectroscopy. It was found that the glass composition was sodiumsilicate based glass. Raman spectroscopy als...

Introduction: Giotto (1266–1337) and his workshop realized c. 1315 the large Crucifix now in the Louvre Museum. The conservation of this masterpiece in 2010–2013 in the C2RMF studios gave the opportunity for a comprehensive investigation of the execution technique through a characterization of the paint layers. The first examinations revealed an original gilding and decoration surrounding the C...

Amorphous Spherical Carbon with Nitrogen (SCN) active carbon has been prepared by carbonization of poly(vinylpyridine-divinylbenzene) (PVPDVB) copolymer. The PVPDVB dehydrogenation copolymer has been quantum chemically (QC) simulated using cluster and periodic models. Scanning electron microscopy (SEM), transmission electron microscopy (TEM) and energy dispersive X-ray (EDX) studies of the resu...

The mineral yuksporite (K,Ba)NaCa2(Si,Ti)4O11(F,OH)⋅H2O has been studied using the combination of SEM with EDX and vibrational spectroscopic techniques of Raman and infrared spectroscopy. Scanning electron microscopy shows a single pure phase with cleavage fragment up to 1.0 mm. Chemical analysis gave Si, Al, K, Na and Ti as the as major elements with small amounts of Mn, Ca, Fe and REE. Raman ...

In the frame of the European project NanoValid, potential candidates of reference nanomaterials are manufactured and systematically characterized in particular with respect to their morphology (shape, size and size distribution). In this study, by exploiting the transmission operation mode in a high-resolution SEM, known as transmission SEM, the potential of this methodical approach is demonstr...
