IntroductionSince the remarkable discovery of high electrical conductivity in polymer materials in 1977 [1], studies on conductive polymers (CP 1 ) have developed into interdisciplinary research expanding in various directions. A significant impetus to the field was given by materials scientists in their attempts to combine the unique properties of conductive polymers with those of other inorganic and organic materials. Thus, in the last two decades, research on the synthesis of CP-based composite materials has flourished and resulted in the development of a great variety of new materials with interesting specifically designed properties. The accumulation of a great number of studies on nanocomposite materials has provoked the recent appearance of several review articles [2-7] attempting to summarize, from different specific points of view, the advances made in the field. Thus, electrochemical aspects [2,7] of CP-based composites, optical and electronic properties [3], polyaniline(PANI)-based nanocomposites [4], the involvement of composites of CPs in chemical sensing [5], and the incorporation of metallocenes in CPs [6] have been extensively discussed.

“…X-ray Magnetic Circular and Linear Dichroism), and 2D μ-XAS mapping. The first area was historically the first to take advantage of EDXAS instruments to track rapid changes in the local and electronic structure of absorber atoms in disordered systems in the fields of biophysics, chemistry and materials science [9][10][11][12][13]. In the second area, EDXAS was found to be well suited in the detection of very small "difference" signals, such as XMCD, thanks to the intrinsic stability of the technique (no moving components) which helps reduce sources of nonstatistical noise.…”

Energy Dispersive X‐ray Absorption Spectroscopy is a now a well‐established method which has been applied to a broad range of applications. Ten years from the construction of beamline ID24 at the ESRF, the first dispersive XAS spectrometer using undulator radiation on a third generation source, we report an overview of recent results in very diverse fields of research, ranging from automotive catalysts to magnetism at extreme conditions. We also illustrate how pushing the instrument to its limits has opened new opportunities, such as an enhanced sensitivity to detection of tiny atomic displacements and the potential for micro‐probe redox and speciation imaging

The development of a curved crystal monochromator of the Laue type for energy-dispersive X-ray absorption spectroscopy is presented. The quality of the X-ray absorption spectra at high photon energies is compared with spectra measured with silicon crystals in the more frequently used Bragg geometry. In the Bragg case, an asymmetric broadening of the reflectivity profile leads to strong distortions of the near-edge fine structure and to a reduction in spectral resolution. The reflectivity profiles of fiat and curved crystals for Laue and Bragg geometry have been calculated using dynamical theory and are compared with experimental data. The new optics have been used for in situ time-resolved X-ray absorption spectroscopy. An example of the application of the technique for the characterization of a Pd catalyst is given. The X-ray absorption fine structure at the Pd K-edge has been measured during the activation and during the heterogeneous catalytic oxidation of carbon monoxide.
