Photo-excited state crystal structures are now possible via photo-crystallography - a technique that pumps optical light upon a crystal which is, in turn, probed by X-ray diffraction. While this technique is still very much in a developmental phase, results have already demonstrated important findings in the area of optoelectronics.
Such photo-crystallography experiments are now being...

Barium titanate (BaTiO3, BT) is the most extensively used perovskite dielectric ceramic material in the electronic industry. Its application includes multilayer ceramic capacitors (MLCs) traditionally made by covering BT with a layer of precious metal and firing. In order to reduce production costs, precious metal electrodes are replaced by base metal electrodes (BME) producing low-cost...

The crystallization of polymorphic compounds is investigated in different fields of materials science to understand the stability of materials and their various conversions. The need to control and manipulate the crystallization processes and particularly the final crystal product requires thorough understanding of the underlying crystallization mechanisms and kinetics. This is especially true...

In this work, a specific preparation procedure is described, for making possible to obtain in one shot structural and compositional characterization of a buried interface at the nanometre scale using a micrometre scale probe. Specific examples based on dispersive micro X-ray absorption spectroscopy, shows that nearly-atomic scale changes in local structure, composition, as well as local...

Third generation synchrotron radiation (SR) facilities are designed to host powerful brilliant radiation sources like undulators and wigglers. The next frontier of SR experiments is represented by the combination in a concurrent set up of different wavelengths, to characterize complex systems where different processes due to the interplay between localized and delocalized electrons, charge...
