SEM/EDX and XPS studies of niobium after electropolishing
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The studies of niobium after electrochemical polishing EP in sulfuric-methanesulfonic acid mixture were performed. The NbOx/Nb surface was studied by SEM/EDX and XPS methods to find out the chemical composition of the ...
Introduction to micro-residues analysis: Systematic use of Scanning Electron Microscope and Energy Dispersive X-rays Spectroscopy (SEM-EDX) on Patagonian raw materials
(Elsevier, 2017-12)
Residue analysis is commonly applied to stone tools functional identification and is often used in conjunction with micro-wear analysis for understanding their past function and also early human behaviour. In spite of their ...
Characterization and distribution of mineral phases in an Amazonian humiluvic Spodosol profile by XRPD, HR-TEM, SAED and SEM–EDX
(2021-06-01)
The Amazonian biome has a fundamental role in the global climate change scenario and the understanding the physicochemical aspect in Amazonian soils is of great importance. The nine horizons constituting a typical Amazonian ...
El uso de pigmentos naturales en el tratamiento de cueros: Identificación bajo microscopia electrónica (SEM-EDX) en piezas líticas experimentalesThe use of natural pigments in the treatment of leathers: identification under electronic microscopy (SEM-EDX) in experimental Stone tools
(Universidad Autónoma de Madrid, 2017-12)
El trabajo sobre cuero ha sido ampliamente documentado en Patagonia meridional, pudiendo identificarse el uso de sustancias colorantes en su tratamiento, no sólo por cuestiones decorativas sino también para una mejor ...
Multi-instrumental characterization of two red pigments in funerary archaeological contexts from northern Chile
(Interciencia, 2015)
This paper reports on an unknown yellowish mineral compound found in an archaeological context from Chorrillos cemetery (Calama, Chile) dating to the Early Formative period (800 - 200 B.C.). We used optic microscopy, SEM, ...
Arqueología de los colores: Análisis MEB-EDX de mezclas pigmentarias en cerámicas prehispánicas de la cuenca del Río Paraná (Provincia de entre Ríos, Nordeste de Argentina)Archaeology of colours. sem-edx analysis of pigment mixtures from pre-hispanic ceramics of the paraná river basin (Entre Ríos Province, Northeast Argentina)
(Museo Chileno de Arte Precolombino, 2015-08)
Se presentan los primeros resultados del análisis fisicoquímico de mezclas pigmentarias rojas y blancas empleadas en la decoración de cerámicas arqueológicas, provenientes de sitios localizados en la cuenca media y baja ...
Investigation of pyrolysis kinetics parameters and thermal behavior of thermochemically modified bagasse for bioenergy potential
(2021-03-01)
Biomass is considering a source of organic carbon, which can replace fossil resources by using pyrolysis process, therefore an efficient biomass thermal modification technology has been target of so much research. The ...
