title: Measurement of absolut Yield of Scintillator Materials

description: The aim of the project is to characterize innovative scintillating materials that should combine all the capabilities required for CEA-LNHB's developments in metrology, in particular the development of laboratory calibration equipment, as well as being portable for operando and in-situ use. This should provide improvement of the new Compton-TDCR (Triple-to-Double Coincidence Ratio) method [2-3]. The scintillator needs to be characterized in terms of the number of light photons produced per deposited energy (scintillation yield) and of the time response of the different components of the scintillating material. This is important for the fundamental understanding of the photonic properties of these innovative materials, with possible benefits for other applications. It is also a way to obtain an absolute curve of scintillator efficiency that could be used for radionuclide metrology and thus driving the base for new methods.

title: Magnetic Structure of NdCoNi Laves Phases

description: This experiment aims to investigate materials for magnetocaloric hydrogen liquefaction. We plan to explore the effect of Ni addition in NdCo2 (NdCo2-xNix) on the structural properties using low-temperature x-ray diffraction. The purpose of the experiments is to determine the structural properties of the materials below and above their magnetic transition temperature. The main goal is to understand the structural deformation present at low temperatures for NdCo2-xNix.

title: In situ/operando combined XAFS/XRD study of Fe-Mo catalysts for continuous CH4 pyrolysis to H2 and carbon nanotubes

description: This proposal focuses on studying transition metal-supported catalysts for methane pyrolysis into high-purity hydrogen and carbon nanotubes. Methane conversion and carbon product types depend heavily on the catalyst properties, but their precise relationship remains unclear. Fe-based catalysts are seen as robust, eco-friendly, and abundant, while the addition of Mo as a promoter boosts catalyst stability and provides extra carbon nucleation sites. The work aims to use in situ/operando XAFS/XRD to examine the Fe and Mo species formed during methane pyrolysis and subsequent regeneration, and their link to methane activation and selectivity toward carbon nanotubes. The findings will support the design of improved catalysts for continuous hydrogen and carbon nanotube production, which holds significant industrial potential.

title: 3D mapping of dislocations-crack tip interaction in SrTiO3 with DFXM

description: Dislocations (line defects) in functional ceramics are generating rapid research interest for both functional and mechanical properties. Despite of recent years’ development for dislocation engineering into various oxides, a major challenge remains: crack initiation and propagation even in dislocation-rich regions can occur unexpectedly and lead to fracture of the samples. To overcome this challenge and better understand dislocation-crack tip interaction in oxides, here we propose to use SrTiO3 as a model system to use DFXM (dark-field X-ray microscopy) for imaging dislocations around cracks. DFXM will provide critical 3D information at micro/mesoscale with high resolution (~100 nm). Our preliminary DFXM test on SrTiO3 suggests this is a promising route. Samples with 4 different dislocation densities at pre-induced cracks will be probed. The spatial distribution of dislocations and their strain fields will be measured to feed our developed dislocation-based fracture mechanics model.

title: Spectro-BCDI of single bi-metallic catalytic nanoparticles during in-situ annealing

description: Heterogeneous catalysts based on nickel–iron (NiFe), platinum–palladium (PtPd), and platinum–nickel (PtNi), and alloys are known to exhibit high activity and selectivity for various catalytic reactions, including CO₂ hydrogenation, CO/NH₃ oxidation, and other hydrogenation reactions. Fundamental questions remain regarding how individual alloy nanoparticles (NPs) evolve structurally and chemically under high-temperature conditions and reactive environments. Here, we propose to investigate the real-time structural (lattice strain, defects, facets, and morphology) and chemical (composition and oxidation states) dynamics of these catalysts using operando spectroscopic Bragg coherent X-ray diffraction imaging (spectro-BCDI). By focusing initially on the annealing step up to 650 °C, we aim to establish how each alloy’s intrinsic structure and chemistry change under reaction temperature conditions. CO2 hydrogenation if time permits.

title: In situ and operando X-ray absorption spectroscopy studies of Cu/ZIF-8, a selective and stable catalyst for CO2 hydrogenation

description: CO2 hydrogenation has shown to be a promising technology for reducing CO2 emission. This process typically employs catalysts composed of copper (Cu), zinc oxide (ZnO), and alumina (Al2O3), with the Cu-ZnO interface playing a critical role in catalytic performance. Recent advances have introduced metal-organic frameworks (MOFs) to stabilize these nanoparticles and prevent sintering. Recently, we developed a new catalyst embedding Cu in zeolitic imidazolate framework-8 (ZIF-8) through ion exchange, showing enhanced activity and stability compared to traditional catalysts. However, understanding the catalyst's behavior under actual operational conditions remains a challenge. In this work, we aim to employ in-situ X-ray absorption spectroscopy (XAS) to study the local environment, electronic structure and oxidation states of Cu under real reaction conditions.

title: Detecting fingerprints of microbial contribution to silicate weathering in basaltic settings: From topsoils to deep subsurface environments

description: Quantifying the contribution of microbes to silicate dissolution rates is one of the main challenges to improve numerical models of silicate weathering, a process that partly controls atmospheric CO2 uptake and Earth’s climate over geologic timescales. Addressing this challenge will require the definition of biosignatures of bioweathering, for which current definition is controversial. Here we propose to use X-ray reflectivity to characterize the physical properties of nm-thick silica-rich layers formed on basaltic glass weathered in biotic and abiotic conditions, taken as a simplified model relevant for basaltic environments that act as major sink of CO2 on Earth. Since our previous works conducted on altered silicate minerals showed that the properties of such Si-rich layers were inherited from the chemical composition of the fluid medium, we expect to get unprecedented data to identify imprints resulting from bioweathering, a necessary step for quantifying bioweathering fluxes.

title: X-ray spectroscopy of bimetallic catalysts for CO2 reduction reaction

description: The development of membrane-electrode assembly flow cells has led to rapid progress in CO2 electrolysis and efforts are currently focused on enhancing catalysts to achieve superior selectivity and activity levels. Bimetallic catalysts have been proposed to enhance the selectivity of the reaction towards the production of C2+ products. The role of the nature of the catalyst and its electronic and atomic structural evolution during the reaction remains however ambiguous. To deepen our understanding of the correlation between the coordination environment of Cu-based bimetallic catalysts and the CO2RR properties, we propose to perform operando X-ray spectroscopy. This project is part of an MSCA-DN (ECOMATES - grant agreement No 101072830) with the development of a tender X-ray operando cell as deliverable. Our project aims at elucidating the local coordination environment and the dynamic behavior of bimetallic catalysts during operation by using ex-situ and operando X-ray spectroscopy.

title: Following Spin-Crossover - 3D Analysis of the electronic effects

description: This proposal seeks to investigate the spin-state and spin-crossover phenomena in metal-organic complexes using high-resolution single-crystal X-ray diffraction and Anomalous Dispersion Refinement (ADR) techniques. These phenomena are critical in fields like molecular electronics and data storage, yet current experimental techniques often lack the three-dimensional resolution needed for in-depth understanding. By utilizing ADR, we aim to resolve electron density distributions before and after a thermally induced spin-crossover,
achieving unprecedented precision in the analysis of the electronic and structural changes involved. The experiment will focus on Ru and Ag-based metal organic complexes, and will combine X-ray Absorption Spectroscopy (XAS) with diffraction data to provide new insights into the interplay between spin states and structural dynamics.

title: Time-resolved X-ray absorption spectroscopy to study hematite Fe2O3 and wüstite FeO phase transitions under laser-shock compression

description: Recent studies of Fe-O phase diagrams have revealed important yet not fully understood phenomena, such as new Fe-O stoichiometries, changes in iron spin and oxidation states, which are important for properly modeling both deep planetary interiors and high-velocity meteorite impacts. The important discrepancies observed between static and dynamic compression phase diagram emphasizes our lack of understanding of the underlying transition mechanisms. X-ray Absorption Spectroscopy (XAS) is particularly well-suited to tackle these questions and explore the interplay between the electronic and atomic structures. In the continuity of our previous experiments at ESRF, we propose Time-Resolved (TR)-XAS at Fe K-edge of laser-shock compressed Fe2O3. Moreover, as FeO has similar transitions but possibly with a different physics, we propose to also investigate this latter thus providing unprecedented knowledge of phase transition mechanisms in iron oxides.
