In Situ Xanes Study Of Cobalt In Co-ce-al Catalyst Applied To Steam Reforming Of Ethanol Reaction
(Elsevier Science BVAmsterdam, 2017)
Extended and local structural description of a kaolinitic clay, its fired ceramics and intermediates: An XRD and XANES analysis
(Elsevier Science, 2016-05)
The thermal transformations processes of kaolinite (K) in kaolinitic clays is known to consist of a dehydroxylation into metakaolin (MK) at ø. 600 °C, followed by the formation of a spinel type aluminosilicate (SAS) at ø. ...
Indium local geometry in In-Sb-Te thin films using XANES and DFT calculations
(Elsevier Science, 2017-12)
In-Sb-Te when is a thin film presents a huge difference in its electrical resistivity when transform from the amorphous (insulating) to the crystalline (conducting) phase. This property made this system one of the main ...
Extended and local structural characterization of a natural and 800 °C fired Na-montmorillonite–Patagonian bentonite by XRD and Al/Si XANES
(Elsevier Science, 2017-03)
A structural characterization of a Patagonian bentonite and its corresponding heating product (800 °C) was carried out. The nature of aluminum and silicon atoms was investigated using Al and Si K-XANES spectroscopy and ...
Structural, electronic and magnetic properties and hyperfine interactions at the Fe sites of the spinel TiFe 2 O 4 : Ab Initio, XANES and mössbauer study
(American Chemical Society, 2019-08-13)
We present here an experimental and theoretical study of the Ti-ferrite (TiFe2O4, ülvospinel). The theoretical study was performed in the framework of Density Functional Theory using the Full-Potential Linearized Augmented ...
Structural, physical and chemical properties of nanostructured nickel-substituted ceria oxides under reducing and oxidizing conditions
(Royal Society of Chemistry, 2016-07)
This work reports the synthesis of nanostructured Ce1-xNixO2-δ (x = 0.05, 0.1, 0.15 and 0.2) oxides prepared by cation complexation route and with the main objective of studying their redox properties using a combination ...
