In Situ Xanes Study Of Cobalt In Co-ce-al Catalyst Applied To Steam Reforming Of Ethanol Reaction
(Elsevier Science BVAmsterdam, 2017)
XANES study of electronic and structural nature of Mn-sites in manganese oxides with catalytic properties
(Elsevier Science, 2005-10)
The characterization of a series of manganese oxides prepared by different methods were performed by X-ray diffraction (XRD) and X-ray absorption near-edge structure (XANES) analysis. Low crystallized phases were found by ...
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. ...
Uranium-bearing francolites present in organic-rich limestones of NW Greece: a preliminary study using synchrotron radiation and fission track techniques
(Springer, 2017-01-01)
Synchrotron radiation techniques (mu-XRF and mu-XANES) were applied to the study of organic-rich phosphatized limestones of NW Greece (Epirus). The results revealed uranium accumulation in areas of the material containing, ...
Speciation of sulphur in asphaltenes and resins from Argentinian petroleum by using XANES spectroscopy
(Elsevier, 2019-08)
Argentinian crude oil samples from different origins have been processed to separate in the four fractions Saturates, Aromatics, Resins, and Asphaltenes (SARA). Asphaltene and resin fractions were extracted using n-pentane ...
Structural study of copper oxide supported on a ceria-modified titania catalyst system
(Kluwer Academic/plenum Publ, 2002-01-01)
A structural study of CuO supported on a CeO2-TiO2 system was undertaken using X-ray diffraction (XRD) and X-ray absorption spectroscopy (XAS) techniques. The results of XRD revealed the presence of only two phases, TiO2 ...
XANES measurements probing the local order and electronic structure of Pb1-xBaxZr0.40Ti0.60O3 ferroelectric materials
(Elsevier B.V., 2015-08-15)
In this study, the electronic and local structures of Pb1-xBaxZr0.40Ti0.60O3 ferroelectric ceramic samples were characterized using X-ray absorption near-edge structure (XANES) measurements. The analysis of XANES spectra ...
