Increased strontium uptake in trabecular bone of ovariectomized calcium-deficient rats treated with strontium ranelate or strontium chloride

Confocal synchrotron-radiation-induced micro X-ray fluorescence of trabecular bone from rats treated with strontium ranelate or chloride revealed that the bone strontium uptake is strongly increased by low calcium diet compared with normal calcium diet.

Design and construction of multicrystal analyser detectors using Rowland circles: application to MAD26 at ALBA

Single- and limited-energy-range multicrystal analyser detectors, the main detectors for high-resolution powder diffraction, are described on the basis of the Rowland circle construction. The conceptual design, key manufacturing parameters, along with the error budget study of MAD26, the device of the high-resolution powder diffraction endstation of ALBA, are presented.

Titanium local structure in tektite probed by X-ray absorption fine structure spectroscopy

The local structure of titanium in six tektites from different strewn fields are compared by XANES and EXAFS spectroscopy and refined Ti—O bond distance. Speculations on the different formation conditions of the tektites are provided.

Capabilities of through-the-substrate micro­diffraction: application of Patterson-function direct methods to synchrotron data from polished thin sections

Various aspects of the through-the-substrate microdiffraction technique and its application to the structural characterization of polished thin sections are investigated on two representative cases. In one of these a new intermediate crystalline phase (provisionally named ilerdite) is found and its structural model derived from Patterson-function direct methods.

An alternative scheme of angular-dispersion analyzers for high-resolution medium-energy inelastic X-ray scattering

A simple four-bounce angular-dispersion analyzer without multiple-beam diffraction or transmission-induced absorption is proposed for developing meV- to sub-meV-resolution inelastic X-ray scattering optics at medium photon energies.

An in situ tensile–shear loading device is described for studying elastomer crystallization using synchrotron X-ray scattering at Synchrotron Soleil on the DiffAbs beamline.

The status of strontium in biological apatites: an XANES investigation

XANES collected at the Sr K-edge and ab initio FEFF9 numerical simulations have been performed to establish a possible relationship between the preparation mode of the calcification (cellular activity and precipitation) and the adsorption mode of Sr²⁺ cations (simple adsorption or insertion). Is it possible to draw a line between life and chemistry through the localization of Sr in apatite? The question is open for discussion.

In situ two-dimensional imaging quick-scanning XAFS with pixel array detector

Two-dimensional imaging quick-scanning XAFS measurements were performed using a pixel array detector.

Time-over-threshold readout to enhance the high flux capabilities of single-photon-counting detectors

The MYTHEN photon-counting ASIC operated in time-over-threshold mode shows an innovative approach towards the development of a detector operating with very high photon intensities while maintaining the single-photon sensitivity for synchrotron radiation experiments.
