EDS (Energy dispersive X-ray spectrometry) is a technique used for elemental analysis of a sample, through detection of characteristic X-rays generated from a sample impacted by an electron beam. STEM (Scanning Transmission Electron Microscopy) is a method to obtain high spatial resolution images with Z-contrast [1]. STEM-in-SEM has recently become a technique of choice for high spatial resolut...

Ilmenite is a vital raw material for the production of metal titanium and titanium-containing materials. In this paper, microstructure chemical transformation natural ilmenite in air atmosphere were investigated by analysis XRF, X-ray diffractometer, SEM-EDS. Results showed that untreated had three layers after oxidation at 800 °C 60 min, which Fe2O3, TiO2 inside mixture layer Fe2O3 turn. Subse...

The Mn-Fe layered double hydroxide using chloride in the interlayer anion was successfully synthesized chemical co-precipitation methods. LDH then applied as adsorbent for arsenic removal from synthetic acid mine drainage. characterizations of SEM and XRD analysis showed that had many different functional groups a high specific surface area adsorption processes. morphological structure by SEM-E...

The chemical-mineralogical characterization of rupestrian paintings in red, white, black and yellow colors, which decorate the rocky walls from archaeological sites Ema Furna dos Índios (Inhuma, Piauí, Brazil) was performed. chemical analyses were performed situ by non-invasive analytical technique X-ray fluorescence spectrometry (XRF) as well laboratory using a non-destructive approach, withou...

Scanning electron microscopy with energy-dispersive X-ray spectrometry (SEM-EDS) was used to characterize a macroscopic artifact from Peru (a Moche cast figure) [1]. A 3D hyperspectral datacube was acquired over 51.2 hours, measuring 11,520 x 9,984 pixels with 2,048 energy channels per pixel; each pixel corresponds to 900 nm in the x and y dimensions. With current technology, interacting with t...

Recently introduced FIB/SEM analysis in microscopy seems to provide a high-resolution characterization of the samples by 3D (FIB) cross-sectioning and (SEM) high resolution imaging. The aim of this study was to apply the FIB/SEM and SEM/EDS analysis to the interfaces of a metal-ceramic vs. two zirconia-ceramic systems. Plate samples of three different prosthetic systems were prepared in the den...
