title: Determination of the martensitic transformation features in a high-entropy shape-memory (TiHfZr)74(NbTa)26 alloy

description: Being developed for medical applications, the (TiHfZr)74(NbTa)26 alloy is a new high-entropy shape memory alloy (HE-SMA); composed of five chemical elements, it exhibits a reversible martensitic transformation (MT) under mechanical loading. As some medical applications may contain a reduced number of grains, a micromechanical analysis in the bulk of the material is mandatory. Elastic constants of this alloy have been determined in a previous experiment (MA5410). So, the aim of this proposal is to determine the MT features of this new HESMA at the grain scale. In that proposal, Diffraction Contrast Tomography (DCT) and topotomogrpaphy (TT) will serve to detect the occurrence of MT and identify martensite variants during in-situ tensile test. Coupling with 3D-XRD and S-3DXRD will allow calculating the critical shear stress of MT. All the experimental data are mandatory for modelling and will serve as input data of a micromechanical finite element model to design structural applications.

title: FastScan - Fast Correlative Scanning SAXS and Visible Light Fluorescence Imaging of Biological Matter

description: The aim of this project is to combine highly complementary imaging methods – i.e., scanning small angle x-ray scattering, fast bright field microscopy and visible light fluorescence microscopy - for the structure determination of components inside biological cells, in particular the cytoskeleton and the nucleus. Importantly, the planned setup will in the future be applicable to a multitude of different sample types, from biological to soft matter and hard condensed matter. Our focus for the upcoming three years will be on (i) model cell lines with a pronounced keratin network, and (ii) biologically relevant heart muscle cells with and without desmin mutants that cause cardiomyopathy. The setup shall be made available to the user community after set-up and commissioning.

title: Investigation by 3D nano-holotomography of the interfacial strength of oxide inclusions in iron

description: Oxide inclusions are an unavoidable side products of steelmaking having detrimental effects on the fatigue and fracture properties of steel, hence their very different local mechanical properties than of the steel matrix in which they are embedded. In the current proposal, we are aiming to implement holographic X-ray nanotomography coupled with step-wise tensile loading in order to enable the observation of void formation as a result of the inclusion detachment from the matrix under external load. The resulting tomographic data will be complemented with finite-element modeling in order to estimate the lower bound of the inclusion - matrix bond strength. The proposed experiments will contribute to the fundamental understanding of external-load driven debonding of oxide inclusions, being one of the primary cause of fatigue failure and will provide valuable information for the ceramics scientific community too.

title: Exploring the Phase Diagram of the Palladium Hydrogen System using Bragg Coherent Diffraction Imaging

description: The goal of this study is to observe the structural evolution of single palladium nanocrystals during
hydrogen absorption and desorption in rarely explored regions of the phase diagram. The Pd-H
system is extremely interesting for its capability to uptake large amount of hydrogen into interstitial
sites with an accompanying lattice expansion. There exist several phenomena that have not been
observed in single nanocrystals such as high temperature and pressure absorption, and absorption
in the supercritical phase. As well as more exotic phenomena such as spinodal decomposition that is
posited to exist in small single crystals. Using Bragg Coherent Diffraction Imaging (BCDI) we are
able to follow in-situ the evolution of the internal and surface strain in individual nanoparticles.

title: Crossover between intra-clusters and inter-cluster dynamics in metallic glasses

description: Revealing the atomic dance in glasses has been always considered an extremely challenging experimental task due to the weak scattering signal of glasses and the long time scales involved in their dynamics. In a recent beamtime, we successfully took advantage of the large coherent fraction of the x-ray beam produced at ESRF-EBS to measure for the first time the intermediate scattering function of a metallic glass on spatial length scales covering both inter-cluster and intra-clusters distances. Our data suggest the existence of a
continuous transition between distinct mechanisms of collective motion on approaching the macroscopic limit. We propose to confirm these results by extending the dynamical range at length scales far from any structural contribution. The results will help clarifying the origin of an anomalous compressed decay of the ISFs in metallic glasses at the atomic level, which is puzzling the community since more than ten years.

title: Operando Investigation of Oxygen Reduction Reaction Electrocatalyst Degradation under different AST protocol in Fuel Cell

description: Fuel cell technology provides a clean and efficient route to convert chemical energy into electricity, with strong potential for sustainable energy systems. The cathode Oxygen Reduction Reaction(ORR) electrocatalyst is critical for performance and durability due to the sluggish kinetics. Understanding its real-time behavior and degradation under operating conditions is essential for improving fuel cell lifetime and guiding research and applications. 
In this proposal, we will study ORR catalyst (Pt/C from Johnson Matthey) degradation under different accelerated stress test protocols using SAXS/WAXS to monitor grain and particle size evolution, correlating changes with degradation pathways such as aggregation, coalescence, and Ostwald ripening. X-ray fluorescence mapping will track Pt distribution during operation. Combining these operando techniques, we aim to achieve a holistic understanding of degradation mechanisms to inform improved catalyst design and enhance fuel cell durability.

title: Analysis of Pb speciation in hydrothermal fluids using high resolution XAS

description: This proposal aims at improving the current understanding of lead (Pb) speciation in hydrothermal fluids using high resolution X-ray absorption spectroscopy (HERFD-XAS). In nature, Pb generally occurs in association with highly sought-after Cu and Zn. As the future supply of Cu and Zn is influenced not only by resource availability but also by the social and environmental sustainability of mining practice, understanding Pb’s potential to act as an environmental contaminant is crucial. Specifically, determining the conditions under which Pb is least mobile is essential. To refine our knowledge on Pb mobilization and complexation with Cl, S, and H2O we propose to conduct in situ HERFD-XAS measurements on hydrothermal fluids up to 600 °C and pressures of 60 MPa at the FAME UHD BM16 beamline.

title: Structural transitions of superconducting quasi-1D materials under high pressure using combined XAS and XRD

description: Recently, the quasi-1D materials (MSe4)2I (M=Ta and Nb) are found to transform into the hybrid crystalline/amorphous structure under pressure, and superconductivity is closely related to the disorder phase. However, the order-disorder structural pathway and the nature of dense disorder phase under pressure remains poorly understood. X-ray absorption spectroscopy has been demonstrated as efficient tool for probing the local structural changes of disorder materials under pressure. Here, we propose to systematically study the crystalline phase transitions, order-disorder transitions of (MSe4)2I (M=Ta and Nb) under pressure using the combined in situ XAS and XRD at room temperature. Through this proposal, we hope to improve our understanding of structure pathway and local structure changes of the quasi-1D materials under pressure and provide a key insight into the correlation between physical properties and disordered structure.

title: Electronic and structural properties of (La,Sm)y(FexNi1-x)4Sb12 skutterudite: local coordination investigation through XAS analysis

description: In the field of thermoelectricity, Co-free filled skutterudites represent an interesting class of materials thanks to their ability to host different amount of filler ions, which tune their conduction regime and transport properties. Aim of this proposal is to perform EXAFS analyses on three samples belonging to the double filled skutterudite system (La,Sm)y(FexNi1-x)4Sb12 at the La and the Sm K-edge to obtain information about the local variations induced by the introduction of two different fillers. Data on a sample of the single filled skutterudite Smy(FexNi1-x)4Sb12 will be also collected at the Sm and Sb K-edge to have a term of comparison. Moreover, the oxidation state of Fe and Ni will be investigated by exploring the XANES region of the spectrum. The so gained information can be of help in the comprehension of the mechanism of thermal conductivity suppression operated by filling in filled skutterudites.

title: Assessing HSIL zeolite crystallization in mixed cation systems

description: This proposal focuses on understanding the role of mixed alkali cation systems in zeolite crystallization using Hydrated Silicate Ionic Liquids (HSILs). Mixed cations significantly influence both the framework and crystallization kinetics of zeolites, with the cation showing the highest affinity for silicates determining the final structure. Using a multi-diagnostic approach—Impedance Spectroscopy (IS), Small- and Wide-Angle Scattering (SAXS/WAXS), and Raman spectroscopy—the project will investigate how mixed cations impact the self-assembly of aluminosilicates in situ.

title: In-situ Powder X-ray Diffraction of Zeolitic Imidazolate Frameworks under Mechanical Impact Induced Water Intrusion

description: The pressurised intrusion of non-wetting liquid in nanoporous materials has emerged as a promising mechanism to yield high-performance energy absorption and impact protection. Herein we propose to use in-situ powder X-ray diffraction (PXRD) at beamline ID09 to study Zeolitic Imidazolate Frameworks (ZIFs) under high-rate liquid intrusion under mechanical impact. The aim is to determine the structural evolution of ZIFs and examine any dynamic effect or intrinsic timescale that determine the energy absorption in practical applications. We carried out our first experiment MA6203 to obtain preliminary results which validated the feasibility of the new method we developed and informed the strategy of improving our setup to be able to test at a higher pressure and measure both intrusion and extrusion processes, which is the main goal of this new beamtime.

title: Enabling deep understanding of Power-to-Ammonia catalysts for renewable fuel production with the help of transient operando photon-in/photon

description: This LTP is motivated by systematic studies on ammonia synthesis catalysts under the realistic conditions of the Haber-Bosch process, as employed for the production of sustainable renewable ammonia at offshore wind power plants. Over the course of 6 beamtime scheduling periods, electronic and geometric structure of active metals (Fe, Ru) as well as of electronic (K, Cs, Ca, Ba) and structural (Al, Si) promoters will be thoroughly studied at the ID26 beamline under stationary and transient conditions. In the course of the LTP a pixel detector will be installed in the TEXS which, together with sets of high quality Johansson crystals, which will enable X-ray Fluorescence Intensity Ratio Detection (XFIRD). Furthermore, a high pressure operando catalysis cell will be developed. The planned investments will enable spatially- and time-resolved operando tender X-ray HERFD-XANES and XES spectroscopy on working catalysts for chemical energy storage and related processes.

title: In-situ Monitoring of Reactive Intermediates in Heterogeneous Oxidation Catalysts via Ti L2,3-Edge NEXAFS

description: Ti-zeotypes play a major role in sustainable industrial oxidation catalysis. Despite large research efforts, to date, many aspects about this family of catalysts remain unclear, including the nature of the active site, in part due to the limited availability of direct (metal-centered) characterization techniques with molecular-level resolution. Peroxo adducts of Ti-zeotypes are being proposed as key intermediates in the epoxidation of propylene and ammoximation of ketones, but their precise molecular structure (mono or dinculear, hydroperoxo, etc.) is heavily debated. In this proposal, we aim to extend our previously developed Ti L2,3-edge NEXAFS methodology for molecular peroxo complexes to the industrial heterogenous catalyst. In situ characterization at the L2,3-edge of early transition metals has rarely been attempted, but is available at ID20. Resolving the structure of the peroxo-intermediate based on direct characterization will have a broad impact in the zeolite community.

title: Probing electronic and spin excitations in superconducting La3Ni2O7/SrLaAlO4 thin films

description: Recently, ambient-pressure superconductivity (SC) with Tc&gt;40 K has been realized in La3Ni2O7 (LNO) thin films grown on SrLaAlO4 (SLAO) substrates that applies in-plane compressive epitaxial strain on LNO, making possible spectroscopic studies on LNO in the superconducting state employing soft X-rays. Our previous RIXS experiments on LNO/LAO, LNO/LSAT and LNO/STO performed at ID32, ESRF revealed that the spectral weight and energy of spin excitations are enhanced by the in-plane compressive strain, and their electronic structure could be effectively tuned by epitaxial strain, suggesting that spin fluctuations likely play a crucial role in mediating electron pairing in the superconducting phase of LNO. However, the spin dynamics and the detailed orbital energy landscape in LNO/SLAO remain to be explored experimentally. We aim to utilize RIXS to probe the spin and orbital excitations of LNO/SLAO thin films, with the goal of gaining deeper insights into the mechanisms underlying SC in LNO.

title: In situ growth and structural characterization of 2D magnetic Cr Chlorides monolayers

description: CrCl2 and CrCl3 van der Waals materials exhibits very different magnetic properties, though the ligand coordination around Cr atoms is similar. Moreover, they are both strongly influenced by the growth substrate. During this experiment we intend to accurately characterize the overall symmetry, unit cell shape and size and other morphological properties of monolayers CrCl2 and CrCl3 respectively grown in situ at the BM32 beamline on Ni(111) and Au(111) single crystal substrate. The collected data will complement magnetic measurements obtained at the ESRF-ID32 beamline on these compounds and have the goal to correlate spin and lattice order in 2D halides.
