We report a systematic study of the relationship between structure and photochromic activity in yttrium oxyhydride (YHO) thin films deposited by DC magnetron sputtering under different ratios of ionization gas (Ar) and reactant gas (H$_2$) flows. The best photochromic performance was observed for intermediate ratios Ar/H$_2$ ≈ 9-12. [...]

Understanding the thermo-mechanical compatibility of composite electrodes is essential for the longterm reliability of solid-oxide electrochemical devices. In this study, we demonstrate a combined in situ synchrotron X-ray diffraction (XRD) and simultaneous dilatometry approach as a rapid and predictive method to quantify both phase-resolved and bulk thermal expansion while tracking microstructural evolution at operational temperatures. [...]

The quality of organic semiconductor [tris(8-hydroxyquinoline)aluminum] Alq3 films and interface of Alq3-Co heterostructure plays a crucial role in the performance of organic spintronic devices. Four Alq3 thin films were deposited at four different substrate temperatures ranging from 30 °C to 90 °C to study the effects of deposition temperature on its structure using x-ray reflectivity (XRR) and Grazing-incidence small-angle x-ray scattering (GI-SAXS) studies.

The crystal structure and the pressure-mediated crystal-fluid interaction of mesolite have been re-investigated by a multi-methodological approach, based on single-crystal neutron diffraction and by in-situ single-crystal synchrotron X-ray diffraction, using a diamond anvil cell. The structure refinement based on neutron intensity data collected at 20 K confirms the general model previously reported for mesolite, but largely improves the description of the hydrogen-bond network (with accurate sites location, their libration regime and interactions). [...]

High-throughput X-ray diffraction (XRD) techniques are revolutionizing materials science by enabling the rapid collection ofhundreds or thousands of diffraction patterns in a single experiment. However, traditional analytical methods like Rietveld refinementbecome a significant bottleneck for quantifying phase fractions from such large datasets, due to their time-consuming,expert-driven nature. [...]

Understanding the nature of active sites in heterogeneous catalysts and how to create them purposefully opens up the possibility of tailored catalyst design. Here we report mixed-valence subnanometre CoOx clusters, consisting of a few metallic Co⁰ atoms on top of Co²⁺, bound to a silicalite-1 support through lattice oxygen atoms as active species for non-oxidative propane dehydrogenation (PDH) to propene. [...]

Investigating materials under extreme pressure using diamond anvil cells (DACs) requires very small samples. X-ray diffraction studies of such samples therefore require beams focused to <5 μm. [...]

Polaritonic chemistry has been emerging as a powerful and fundamental paradigm in materials science, offering unconventional ways to manipulate molecular and material properties by engineering light–matter interactions. By hybridizing molecular excitations with confined electromagnetic fields to form polaritonic states, this approach enables direct modulation of energy landscapes, bond strengths, and transition pathways in materials without altering their chemical composition.
