Recent experimental and theoretical developments in time-resolved X-ray spectroscopies

Capturing the evolving geometric and electronic structure in the course of a chemical reaction or biological process is the principal aim of time-resolved X-ray spectroscopies. Recent technological and methodological improvements, such as high repetition r ...

X-ray Spectrometry and imaging for ancient handwritten document

Giorgio Margaritondo, Frédéric Kaplan, Fauzia Albertin, Marco Stampanoni

We detected handwritten characters in ancient documents from several centuries with different synchrotron x-ray imaging techniques. The results were correlated to those of x-ray fluorescence analysis. In most cases, heavy elements produced high image quali ...

Uniform TiO2/In2O3 surface films effective in bacterial inactivation under visible light

César Pulgarin, Juan Kiwi, Sami Rtimi, Rosendo Sanjines

This study shows that the surface modification of TiO2 is an effective route to increase the TiO2 absorption in the visible region up to similar to 600 nm for photocatalytic applications. The In2O3 decorated TiO2 films on polyester obtained by reactive spu ...

X-ray induced demagnetization of single-molecule magnets

Harald Brune, Stefano Rusponi, Jan Gui-Hyon Dreiser

Low-temperature x-ray magnetic circular dichroism measurements on the endohedral single-molecule magnet DySc2N@C-80 at the Dy M-4,M-5 edges reveal a shrinking of the opening of the observed hysteresis with increasing x-ray flux. Time-dependent measurements ...

Structure analysis of the YBCO layer in Ag/YBCO/metal oxide buffer/Hastelloy composite tape before and after 107 MeV Kr17+ irradiation

Philippe Buffat, Marco Cantoni, Elena Suvorova Buffat

The effects of 107 MeV Kr-84(17+) ion irradiation on YBa2Cu3O7-x-based second-generation coated conductors were investigated using a combination of transmission electron microscopy, diffraction and X-ray energy dispersive spectrometry. Defects 3-5 nm in di ...

A cascade through spin states in the ultrafast haem relaxation of met-myoglobin

Majed Chergui, Frank van Mourik, Cristina Consani

We report on a study of the early relaxation processes of met-Myoglobin in aqueous solution, using a combination of ultrafast broadband fluorescence detection and transient absorption with a broad UV-visible continuum probe at different pump energies. Reco ...

Multivariate statistical analysis as a tool for the segmentation of 3D spectral data

Cécile Hébert, Marco Cantoni, Guillaume Lucas, Pierre Burdet

Acquisition of three-dimensional (3D) spectral data is nowadays common using many different microanalytical techniques. In order to proceed to the 3D reconstruction, data processing is necessary not only to deal with noisy acquisitions but also to segment ...

Preparation and characterization of multiwalled carbon nanotube/In2O3 composites

László Forró, Arnaud Magrez, Klara Hernadi

We have prepared multiwalled carbon nanotube (MWCNT)/In2O3 composites using a simple impregnation method. The precursor compound indium(III) chloride (InCl3) was used to cover the surface of MWCNTs and distilled water was used as solvent. The applied mass ...
