Journal ArticleDOI
Mechanism of anion retention from EXAFS and density functional calculations: Arsenic (V) adsorbed on gibbsite
Ana Cláudia Queiroz Ladeira,Virginia S. T. Ciminelli,Hélio A. Duarte,Maria do Carmo Martins Alves,Aline Y. Ramos +4 more
TL;DR: X-ray absorption fine structure spectroscopy and density functional calculations were used to determine the structural model of arsenic surface complex on gibbsite mineral in this paper, which showed that As(V) forms an inner sphere bidentate binuclear complex on the surface of Al oxyhydroxyl octaedra.
Journal ArticleDOI
Incorporation of Ni into natural goethite: An investigation by X-ray absorption spectroscopy
Maria Luiza Carvalho-e-Silva,Aline Y. Ramos,Hélio C. N. Tolentino,Jacinta Enzweiler,Silvania Maria Netto,Maria do Carmo Martins Alves +5 more
TL;DR: In this article, X-ray absorption spectroscopy was used to obtain structural information on the local environment around Ni in natural Ni-containing goethite (1.8-4.1 mol% Ni) from Vermelho lateritic deposit of Serra dos Carajas (Brazil) and in synthetic analogues.
Journal ArticleDOI
A 2.3 to 25 keV XAS beamline at LNLS.
Hélio C. N. Tolentino,Aline Y. Ramos,Maria do Carmo Martins Alves,Raúl A. Barrea,Edilson Tamura,Julio C. Cezar,N. Watanabe +6 more
TL;DR: A technical description of the main beamline components is given, and results concerning important points, such as available flux at low and high energies, harmonic contamination, energy resolution and stability, are presented.
Journal ArticleDOI
Structural and electronic relaxations around substitutional Cr3+ and Fe3+ ions in corundum
Emilie Gaudry,Amonmat Kiratisin,Philippe Sainctavit,Christian Brouder,Francesco Mauri,Aline Y. Ramos,Andrei Rogalev,José Goulon +7 more
TL;DR: In this article, the local arrangement of atoms surrounding a substitutional Cr3+ and Fe3+ ion in α-Al2O3 has been studied experimentally using natural x-ray linear dichroism absorption at the Cr and Fe K edge.
Journal ArticleDOI
Size of Cd(S,Se) quantum dots in glasses: Correlation between measurements by high‐resolution transmission electron microscopy, small‐angle x‐ray scattering, and low‐frequency inelastic Raman scattering
Bernard Champagnon,Bruno Andrianasolo,Aline Y. Ramos,M. Gandais,Mireille Allais,Jean‐Pierre Benoit +5 more
TL;DR: In this paper, the average sizes of Cd(S,Se) quantum dots in glasses have been measured for the same samples by using three methods: high-resolution transmission electron microscopy, low-frequency inelastic Raman scattering, and small-angle x-ray scattering.
