title: High performace Ni-based catalyst prepared vis SOMC for dry reforming of methane

description: Ni-based catalysts have garnered interest for the dry reforming of methane (DRM) due to their cost-effectiveness and notable Abstract: activity. Via the surface organometallic chemistry method, which has emerged as a powerful tool to synthesize well-defined model catalysts for reactions, we have synthesized narrowly size-distributed monometallic Ni nanoparticles on Al2O3, which shows notable catalytic DRM performance. Aproposed to be favoured at high temperature, 850 C, forming carbide-like phase, which will help the carbon gasification, thus preventing coke formation. At lower reaction temperatures, insertion of carbon will be hindered, hence its accumulation on the surface instead, ultimately leading to catalyst deactivation. In this study, Li was found to prevent catalyst deactivation at lower reaction temperature, likely because Li facilitated the carburization process, helping the carbide-like phase formation, and thereby preventing coke formation at lower temperatures.

title: Si/SiGe heterostructure characterization for Qubit optimization

description: High and uniform valley-splitting of electron energy levels in Silicon/Silicon Germanium (Si/SiGe) heterostructures is one of the dominant limiting factors to scale up silicon-based quantum processors. Here, we propose a study of the strain and surface/interface sharpness homogeneity in a Si/SiGe heterostructure as a function of the thermal budget required to make quantum dots and Hall-bar structures. The correlation in between these metrics and the valley-splitting of electrons hosted in this heterostructure will be investigated. We will thus combine the unique strain mapping qualities of ID01 proven in earlier studies in such thin layers with our capacities of probing all relevant functional aspects required for the realization of Si Qubits. This study will provide deeper understanding of the material characteristics impact on the electron properties and enables the optimization of heterostructure for quantum computing hardware.

title: Compressive Failure of Novel Hybrid Boron-Carbon Fibre Reinforced Composites

description: Effective use of carbon-fibre-reinforced polymer (CFRPs) composites is critical for the aerospace, defence and sport industries. Under tension, it is usually possible for CFRP components to take advantage of the high strength of carbon fibres. However, under compression, CFRPs typically fail by a microscopic instability mechanism at loads that are significantly lower. Hybridising CFRPs with boron fibres holds the potential to delay this kink/buckling instability and hence achieve much high compressive strengths. However, little is known about the mechanism by which boron fibres may stop the compressive failure instability in CFRP. Here we will observe the failure sequence in 3D for the first time. This will enable us to model the process and help us develop optimised carbon-boron composite hybrids. Their superior compressive response will lead to lighter structures in the aerospace, defence and sport sectors.

title: HUB Proposal: Human Organ Atlas Hub (HOAHub)

description: This HOAHub will create a physical and virtual Hub which uses HiP-CT to scan whole human organs with local cellular resolution, producing a “Human Organ Atlas in Health and Disease”. It will bridge clinical imaging (centimetre scale) to molecular modalities (nanometer scale), providing unprecedented insights into our bodies, helping cure or mitigate diseases from neuro-degeneration to cancer. The HOAHub will bring together interdisciplinary groups to produce the novel experimental and computational technologies needed to analyse and interpret the scale-bridging data. By transforming HiP-CT into an efficient tool, HOAHub will enable the clinical impact of synchrotron imaging to be realised. Through these scientific and technical efficiencies, HOAHub will not only advance biological, computational and medical fields, it will provide anatomical training resources and a new Gold Standard for validating CT, MRI and 3D histology, inspiring new techniques and real-world clinical insights.

title: Understanding selective oxidation of light alkanes over bio-mimetic Fe-MOFs by X-ray spectroscopy and diffraction

description: This proposal aims to explore the selective oxidation of light alkanes over novel Fe MOFs catalysts by a comprehensive suite of synchrotron techniques. Using Fe K-edge XAS and vtc-XES, we will selectively probe the different Fe active sites, while tracking the long-range stability of the MOF scaffold by PXRD under operando conditions. The interest of investigating Fe-MOFs comes from their potential of mimicking the unique selectivity of Fe enzymes and thus holding promise for the selective oxidation of light alkanes, such as propane, and ideally methane. Similar Fe-MOFs structure with different active site locations (MOF node vs functionalized linker) will be studied, with variation in activation and reaction conditions, guided by laboratory test results. The resulting spectroscopic details on the active Fe sites and reactive intermediates are expected to unlock electronic/structural insights, allowing the design of improved MOF-based selective oxidation catalysts.

title: Investigating How Print Parameters Drive Interfacial Failure in 3D Printed Medical Prosthetics

description: Interfacial delamination is a critical failure mode of 3D printed polymer prosthetics and is driven by residual strain formation during fabrication. However, the mechanical response of these interfacial strains, which are highly sensitive to printing parameters, are poorly understood which is essential to optimise material fabrication. Using in-situ X-ray scattering we have developed a proof-of-principle approach to visualise interfacial strains stored within the polymer network structure of 3D printed test specimens. Our results demonstrate the feasibility of this approach to visualise polymer strains at high spatial resolutions in photo-cured materials. We now aim to extend the relevance of this work towards clinically based additive manufacturing to determine how parameters such as print angle and layer thickness impact the magnitude and vector of interfacial strains.

title: Defects in Phase Change Materials: an XPCS Study

description: Despite their significance in technological applications, the behavior of defects in amorphous and crystalline phase-change materials is not yet fully understood. To address this, we propose an X-ray Photon Correlation Spectroscopy (XPCS) study to examine the formation and evolution of photo-induced defects as a function of dose and exchanged momentum. This method has already demonstrated its effectiveness in studying defect dynamics in prototypical glasses.

title: Fathoming sequestration and enrichment of rare-earth elements in marine deposits

description: Rare earth elements (REE) are essential to modern life, yet we know little about how they concentrate at Earth’s surface, especially on the seafloor, which holds vast reserves. The underlying mechanistic pathways leading to some of the highest elemental enrichments in supergene ores is a long-standing geochemical and crystallochemical enigma. To advance the field, we propose to determine how light (LREE = Ce-Nd), medium (MREE = Gd-Dy), and heavy (HREE = Er-Yb) REE are incorporated in apatite-rich sediments at the atomic scale. The structural results will inform atomistic calculations that will be employed to model the thermodynamics and kinetics of the chemical reactions at the seawater-apatite interface. The Long Term Proposal is supported by an ERC Advanced Grant awarded to the ESRF and the Ecole Normale Supérieure of Lyon.

title: Elucidating the cooperative role of Fe sites in NiFe-based dual-atom catalysts in oxygen evolution reaction by operando X-ray absorption spe

description: We aim to elucidate the formation of catalytically active sites in atomically dispersed NiFe-based dual-atom catalysts using operando X-ray absorption spectroscopy (XAS). In this project, we have developed a novel coordination-tailored synthesis route to prepare two distinct heteronuclear Ni/Fe dual-atom catalysts featuring nitrogen and oxygen coordination. The observed differences in catalytic behavior highlight the critical role of coordination environments, which we aim to unravel through XAS.
Additionally, we propose to investigate the Ni/Fe environments as a function of the Ni/Fe composition ratio, in conjunction with recently obtained operando synchrotron Mössbauer spectra. Notably, operando studies are expected to reveal the cooperative role of Fe sites and their dynamic behavior. The data collected in this experiment will also aid in interpreting our Mössbauer spectra, providing further evidence of Fe’s cooperative role in the reaction process.

title: Intragranular strain scanning 3DXRD experiments on the ferromagnetic phase transition in (Mn,Fe)2(P,Si) magnetocaloric compounds

description: In the high-performance and low-cost (Mn,Fe)2(P,Si) magnetocaloric compounds the ferromagnetic phase transition is accompanied by latent heat. The transition temperature TC can be conveniently tuned around room temperature by changing the Mn/Fe and P/Si ratios. This system is a very promising candidate for magnetic cooling and power conversion applications. 
A key limitation for the application of these materials is their brittle mechanical properties that potentially limit their cycle life during the operational thermo-magnetic cycling. At TC the hexagonal unit cell shows a sizeable change in the c/a ratio of the lattice parameters, resulting in significant shear stresses near the ferromagnetic (FM)/paramagnetic (PM) interfaces at TC. Intragranular orientation and strain scanning 3DXRD experiments will provide a unique insight in the local strains near the FM/PM interfaces in both single-crystalline and poly-crystalline samples during thermal and magnetic field scans.

title: The evolution of the electronic, structural, magnetic (macroscopic and elementspecific) properties of LaFe12B6 across the field-induced firs

description: In the proposed experiment, we want to study a first-order phase transition (FOT) near 50 K from the antiferro-(AF) to ferromagnetic (FM) state in LaFe12B6. The FOT implies a strong interrelation between the crystal structure and the magnetic sublattice of the sample, but its mechanism is yet to be fully understood. Recently, we have developed a unique setup at ID12 of ESRF to measure simultaneously macroscopic properties (magnetization, magnetostriction, magnetocalorics, resistivity…) and element specific atomistic properties (XAS/XMCD). Using such device to investigate LaFe12B6, we will be able to correlate the FOT in atomistic and macroscopic approach. In addition, XMCD will probe the magnetic moment on La during the FOT, which is expected to be non-null based on recent experiments performed on LaFe13Si measurement. These results will help understanding the FOT based on a material with potential cooling application like magnetocaloric hydrogen liquefaction.

title: Study of exsolution mechanism in ferrite-based materials doped with Ni and Cu through in-situ diffraction for Rietveld and Paid Distribution

description: The exsolution method for the synthesis of supported nanoparticles has been gaining much attention in the last decade due to its enhanced electrocatalytic properties. Ferrite-based materials , which are characterized by a particularly electrochemical activity, have been largely explored for the exsolution from B-site of reducible non-noble metals/alloy. Hereby, we propose to investigate the exsolution mechanism in a general system La0.9-αSrαFe1-xMxO3 [with α = 0.1, 0.35, and Mx = Ni0.1, or (Ni0.05, Cu0.05)]. Our aim is to investigate the structural changes that occur during the Ni, Cu and Fe exsolution process to form alloy NPs. We believe, diffraction data analysed by Rietveld method combined with Paid Distribution Function will be seminal to investigate the structure at atomic level of matrix and exsolved nanoparticles and achieve important correlations with the electrochemical properties of the materials.

title: Anomalous angular anisotropy of excitonic spectra

description: The goal of the proposal is to validate the theoretical prediction of an anomalous angular anisotropy of excitonic peaks around Bragg reflections in the dynamical structure factor S(q,ω) measured by inelastic X-ray scattering (IXS) in materials with strongly bound excitons. The prediction will be verified in hBN, a prototypical layered compound characterised by strong excitonic effects, where previous combinations of IXS experiments and theoretical simulations have already proven their accuracy. The predicted anisotropy is due to the electron-hole exchange interaction and has a general validity in crystalline materials. The beamtime will demonstrate that its measurement by IXS is a direct way to quantify the impact of the electron-hole exchange interaction on electronic excitations.

title: Investigating the Light and Magnetic Field Interplay in Plasmonic Catalysis using XAS/XES and XMCD studies

description: We demonstrate a 150% enhancement in the catalytic activity of plasmonic catalysts under a 560 mT magnetic field, a breakthrough in plasmonic catalysis. This enhancement arises from spin polarization, magnon excitations, and Lorentz forces, prolonging hot carrier lifetimes. However, the mechanisms of magneto-plasmonic catalysis remain unclear. We propose X-ray spectroscopy (XAS, XMCD) to probe electronic structure and spin polarization under light and magnetic fields. We anticipate charge carrier separation shifts XAS edges, unveiling new insights into magnetic field effects on plasmonic catalysts. By successively increasing the complexity of the experiments, we anticipate learning how magnetic field modulates electronic structure in plasmonic catalysts, and spin dynamics in the presence of light providing a novel perspective on the enhancement of catalytic activity.

title: Probing chiral magnons in an altermagnet candidate

description: Altermagnetism defines the third class of magnets, showing characteristics of both antiferromagnetic (AFM) and ferromagnetic (FM) properties, and are therefore promising for spintronic applications. Due to unique symmetry considerations, altermagnets possess zero net magnetization, but nonrelativistic band splitting and chiral magnons, the direct observation of which remains a challenge. Here, we propose to use resonant inelastic x-ray scattering (RIXS) at Mn L3 edge with circular polarization to detect the dispersive chiral magnons in a two-dimensional altermagnet candidate La2O3Mn2Se2. Our experiment serves as one of the first attempts to directly probe chiral magnons and will help us to better understand this new class of magnets.

title: Understanding Cation Effects Through Interfacial Water Structure in Alkaline Hydrogen Evolution on Single-Crystal Platinum Electrodes

description: The structure of one of the key model alkaline water electrolysis interfaces – the Pt/aqueous interface - remains poorly understood. Precise in situ structural elucidation is crucial to better understand (and thus, optimise) the factors governing electrocatalytic reactivity. Significant discrepancies in the cation-concentration dependence of the hydrogen evolution reaction activity between Pt(111) and Pt(110) have previously been observed, namely that the former surface displays no cation concentration dependence, whereas the latter displays a marked dependence at the same electrolyte pH. These discrepant trends suggest that the structure of the electrode-electrolyte interface differs significantly between the two Pt facets. To resolve this, we propose the use of in situ high energy surface x-ray diffraction studies to elucidate the effect of cation identity and concentration on the interfacial water structure and near-surface cation arrangement/occupancy near Pt(111) and Pt(110).
