Autor: Marc Tanti, Camille Berruyer, Paul Tafforeau, Adrian Muscat, Reuben Farrugia, Kenneth Scerri, Gianluca Valentino, V Armando Solé, Johann A Briffa

Publikováno v: PLoS ONE, Vol 16, Iss 12, p e0260707 (2021)

Propagation Phase Contrast Synchrotron Microtomography (PPC-SRμCT) is the gold standard for non-invasive and non-destructive access to internal structures of archaeological remains. In this analysis, the virtual specimen needs to be segmented to sep

Stepwise Transition of the Tetra-Manganese Complex of Photosystem II to a Binuclear Mn2(μ-O)2 Complex in Response to a Temperature Jump: A Time-Resolved Structural Investigation Employing X-Ray Absorption Spectroscopy

Autor: Pavel Pospíšil, Haumann Michael, V. Armando Solé, Holger Dau, Jens Dittmer

Publikováno v: ResearcherID

In oxygenic photosynthesis, water is oxidized at a protein-cofactor complex comprising four Mn atoms and, presumably, one calcium. Using multilayers of Photosystem II membrane particles, we investigated the time course of the disassembly of the Mn co

Geometry and Hydration Structure of Pt(II) Square Planar Complexes [Pt(H2O)4]2+ and [PtCl4]2- as Studied by X-ray Absorption Spectroscopies and Quantum-Mechanical Computations

Autor: Regla Ayala, Adela Muñoz-Páez, and V. Armando Solé, Enrique Sánchez Marcos, Sofia Diaz-Moreno

Publikováno v: The Journal of Physical Chemistry B. 105:7588-7593

The geometrical structure of the tetraaquo and tetrachloro Pt(II) complexes in aqueous solutions has been studied by means of X-ray absorption spectroscopies (EXAFS and XANES), combined with quantum-mechanical computations. The latter were carried ou

Online collection and analysis of X-ray fluorescence spectra on the macromolecular crystallography beamlines of the ESRF

Autor: J. E. McCarthy, Sean McSweeney, Gordon A. Leonard, Matias Guijarro, V. Armando Solé, Dario Marrocchelli, Didier Nurizzo, José Gabadinho, Antonia Beteva, Christoph Mueller-Dieckmann

Publikováno v: Journal of Applied Crystallography. 42:333-335

X-ray fluorescence (XRF) measurements on solutions or crystals of biological macromolecules provide additional information that can be used in structure determination and/or refinement protocols. Here details are presented of an experimental setup, e

Multilayers quantitative X-ray fluorescence analysis applied to easel paintings

Autor: Laurence de Viguerie, V. Armando Solé, Philippe Walter

Publikováno v: Analytical and bioanalytical chemistry. 395(7)

X-ray fluorescence spectrometry (XRF) allows a rapid and simple determination of the elemental composition of a material. As a non-destructive tool, it has been extensively used for analysis in art and archaeology since the early 1970s. Whereas it is

Applications of synchrotron-based micro-imaging techniques to the chemical analysis of ancient paintings

Autor: V. Armando Solé, Javier Chillida, Philippe Walter, Jean Susini, Yoko Taniguchi, Emilie Checroun, Marine Cotte

Publikováno v: Journal of Analytical Atomic Spectrometry. 23:820

Ancient paintings are complex materials in terms of chemical analysis because they are usually made of organic/mineral, amorphous/crystallized, major/minor mixtures, evolving with time, and organized in micrometric multi-layered arrangements. In this
