title: Sustainable cooling and thermal energy storage solutions based on long chain alkylammonium halide salts with solid-to-solid phase transition

description: Thermomaterials are compounds with substantial thermal changes associated with solid-to-solid phase transitions. These materials could play an important role in environmentally friendly alternative refrigerants and thermal energy storage. Decoding the structural origins of the high entropy solid-solid phase transitions is an ongoing challenge of the field. Promising thermomaterials are those based on long chain alkylammonium halide salts, due to their large, reversible phase transition near ambient temperature. This proposal will examine key materials, (C10H21NH3)Cl, (C10H21NH3)(BF4) etc., by conducting single crystal and powder synchrotron-based diffraction measurements in situ with variable temperature and pressure. We will combine this data with thermodynamic parameters obtained from variable temperature and variable pressure differential scanning calorimetry. These studies will offer essential insights on the key structure mechanisms that underpin the solid-solid transitions.

title: Piezoelectric and thermal strain in AlGaN/GaN-based HEMTs in operation

description: We propose to acquire operando scanning X-ray diffraction microscopy (SXDM) maps on Al(Ga)N/GaN-based HEMT devices in operation mode. The study aims to probe the lattice distortion in the active layer of the device due to inhomogeneities in the electric field and temperature distribution.

title: In situ X-ray diffraction and imaging of intergranular corrosion in molten chloride salts

description: This proposal aims at better understanding intergranular corrosion in molten salts. Molten alkali-alkaline earth chloride salts are promising heat transfer fluids for solar power plants and future molten salt reactors, where they could also act as fuel components. Their use raises important challenges related to the selection of structural materials in contact with molten salts. Indeed, Fe- and Ni-based alloys are corroded in contact with molten salts and often display intergranular corrosion. To solve this urgent concern, one needs to understand corrosion mechanisms and kinetics, especially the evolution of grain boundaries (GB). To do so, we want to monitor corrosion in situ by using 3D X-ray diffraction (3DXRD) and tomography (PCT). These experiments will be coupled with ex situ 3D diffraction contrast tomography (DCT) and scanning XRD (SXRD) before and after corrosion to access higher spatial resolution and retrieve a multiscale overview of corrosion in molten salts.

title: Resolving the structural dynamics of Cu epitaxial thin films model electrocatalysts during the electrochemical CO2 reduction

description: Copper electrocatalysts are unique in catalysing the formation of carbon-carbon bonds, an essential first step for producing C2+ products during electrochemical CO2 reduction (CO2RR). Intermittent oxidation of Cu nanocatalysts further enhances the selectivity towards C2+ products, especially ethanol, but the mechanistic understanding is limited. We developed a method for producing Cu epitaxial thin films, which provide a versatile alternative for bulk single crystals, especially under strongly restructuring conditions such as the pulsed CO2RR. Here, we will use HE-SXRD to study the structural dynamics of both the surface as well as the bulk of such films under CO2RR conditions. From these experiments, we expect to track the transition from changes in the surface structure to the formation of bulk Cu2O. The results of these experiments enable us to optimize the design/operating conditions of Cu CO2RR electrocatalysts based on a mechanistic understanding rather than empirical evidence.

title: Unraveling temperature-dependent structural instabilities in halide double perovskite nanocrystals

description: The development of colloidal nanocrystals as next-generation semiconductors relies heavily on understanding their structure with atomic-level precision, which is critical for interpreting and predicting the interaction between charge carriers and their lattice. In particular, halide perovskites are characterized by highly deformable octahedra frameworks, which makes conventional pictures based on phase diagrams inadequate to account for their structural subtleties; halide double perovskites with alternating octahedral units add one further layer of complexity. With the present proposal, we plan a combined XAS/TS approach to characterize the structural response of halide perovskite nanocrystals in a wide temperature range relevant to optoelectronic applications and provide a comprehensive description of their local structure and dynamics across different length scales.

title: Carbonyl surface modification of Al2O3 to synthesize tailored noble metal catalytic sites: from single atoms to sub-nano clusters

description: Noble metal catalysts are essential for heterogeneous catalysis. We have modified supports with carbonyl groups to create anchor sites that allowed the production of highly dispersed structures that maximize the exposure of such metals. Our preliminary data shows that these materials feature unique structures of atomic and sub-nano cluster metal structures supported on Al2O3, with unprecedented atomic precision. We now seek to characterize the exact chemical environment of these metal sites (Pd, Ru, Rh, Pt, and Ni) using XAS-XRD. Specifically, the state-of-the-art operando XAS at SNBL will allow us to identify how noble metal ions re-disperse during calcination and reduction processes and to better understand the essential role that surface carbonyl ligands have proven to play in our composites. This insight is of utmost importance to turn our carbonyl modification strategy into a general tool for the synthesis of supported noble metal catalysts with maximized metal utilization.

title: A high-resolution 3D map of manganese in the brain of a zebrafish model of manganese neurotoxicity.

description: Manganese (Mn) neurotoxicity causes a disabling movement disorder associated with psychiatric symptoms. We have developed a zebrafish model of Mn neurotoxicity by knockout of the Mn uptake transporter Slc39a14 in order to study the effects of excess Mn on neuronal function. A remaining challenge is to determine the spatial Mn distribution within the zebrafish brain and link functional deficits with regions of Mn accumulation.
The ID16A nanoimaging beamline will allow generation of a cellular resolution 3D map of Mn within the zebrafish brain. Combination of the beamline’s MicroXRF, phase contrast imaging, and tomographic approaches will provide an unprecedented improvement in our ability to determine the specific neurons and brain regions in which Mn accumulates, and how that affects brain function and behaviour. Together with our ongoing spatial transcriptomic and behavioural studies, this will further our understanding of the disease pathogenesis underlying Mn neurotoxicity.

title: Investigation of time-dependance speciation of gold-based drugs within cancer cells by cryo-X-Ray Absorption Spectroscopy

description: Organometallic gold complexes bearing biphenyl and diphosphine chelating ligands of the general formula [(C^C)Au(NHC)(PR3)]+ present variable antiproliferative activities depending of the PR3 ligand considered. We could evidence by cryo-XRF microscopy (ESRF, project LS-3277) the variable gold uptake and intracellular localization depending of the PR3 ligand after 4h incubation. However, we evidence by cryo-XAS spectroscopy the complete similar metabolization of each complex after the same incubation time (ESRF, project LS-3235). We now apply for beamline time at FAME UHD to perform cryo-XAS measurements on cancer cells treated with our gold complex for shorter incubation times (30 mn and 1 h) to study the kinetics of cellular metabolization in relationship with the phosphine ligand. This would represent the first structure-speciation relationship study of gold(III) complexes inside cancer cells. This project is financially supported by ITMO Cancer (project Goldspec no. 23CP039-00).

title: X-ray study of the 8x8 beta-Si3N4(0001)/Si(111) reconstruction

description: By surface x-ray diffraction we aim to solve the 3D structure of the 8x8 beta-Si3N4(0001) reconstruction on Si(111). This system draws attention because of its potential as sub-nanometer thin insulator layer for metal/silicon junctions. In the literature, although several chemical and the electronic properties have been investigated, there is no consensus on the atomic structure of this interface. The high computational requirements still prevent the simulation of whole structure because of the large number of atoms participating in the 8x8 supercell. The precise identification of the atomic positions constituting the interface can be relevant for the understanding of the electronic band structure, a first step towards the exploitation of this interface in future electronic devices.

title: Temperature dependent dynamics of multi-responsive hydrogels

description: Access to the rotational dynamics is essential for magnetic nanoparticles (MNPs) and their use in magnetically-induced hyperthermia, where heat is generated due to the rotation of the MNPs in a medium by exploring them to an alternating magnetic field. By embedding MNPs in a thermo-responsive hydrogel, the structure shrinks with increasing temperature and will change the translational and rotational diffusion of the NPs. Therefore, we propose an experiment to measure these smart magnetic systems' dynamics in dependence on temperature and magnetic field strength using XPCS and XCCA. We want to investigate the translational as well as the rotational dynamics of anisotropic active cobalt ferrite nanoparticles embedded in the smart polymer matrix. We want to clarify the rotational movement of the NPs within the gels by triggering the system with different magnetic field strengths and temperatures. This would enable the control of the smart magnetic system for hyperthermia applications.

title: Measuring exciton polaritons in lithium triborate (LBO) by x-ray parametric down-conversion

description: In previous experiments on x-ray parametric down-conversion (XPDC), we successfully resolved the splitting into highly asymmetric (i.e., x-ray and EUV) photon pairs. We observed remarkable scattering features that revealed the hybridization of this EUV photon with matter, thus forming an EUV polariton. In this way, XPDC provides a rare and novel insight into strong light-matter coupling in the EUV regime. Here, we aim to extend this capability to the class of ‘exciton polaritons’: Exploring XPDC for the first time near a core-shell resonance, we expect the down-converted EUV photon to hybridize strongly with this electronic resonance. We propose to use lithium triborate (LBO), which is known for its high optical nonlinearity, while also exhibiting two promising exciton resonances (i.e., before the K-edge of Boron and Lithium). We aim to observe EUV exciton polaritons at both resonances, obtaining unprecedented insights into their formation, life-time and electronic structure.

title: Search for soft lattice modes in the magnetic kagome metal YbFe6Ge6

description: Due to magnetism, topological properties, electron correlations and their interplay, magnetic kagome materials are attracting attention as a platform to explore exotic quantum phases [1]. Recent studies on the correlated kagome magnet FeGe [2] exemplify this interplay-driven phenomenon, revealing an unprecedented CDW order, whose dynamics unveils an intriguing dimerization driven order-disorder scenario [3]. Similar to the 166 ScV6Sn6 compound demonstrated a soft lattice dynamics [4], YbFe6Ge6 hosts 2 kagome planes per unit cell and features the same magnetic order as FeGe. In this proposal, we aim at investigating the lattice dynamics of the antiferromanetic YbFe6Ge6 by means of diffuse and inelastic x-ray scattering (IXS) and search for diffuse signals, characteristic of pre-transitional fluctuations of soft modes. We intend to comprehensively measure the temperature and momentum dependence of the low energy acoustic and optical phonons by means of high-resolution IXS.

title: Moving across Pt catalysts with different size combining computations with cutting-edge X-ray spectroscopies

description: Pt-based heterogeneous catalysts are widely used materials for key reactions in industry like selective hydrogenations. Because of their complexity, synchrotron techniques are often used to study the active metal phase. Recent development in computational chemistry allowed for the calculation of XAS and XES spectra that can describe and possibly predict key structural and functional properties. In this context, the present study aims at acquiring top-level HERFD-XAS and resonant XES data on several Pt-based materials and create a solid experimental/simulated benchmark for spectroscopic properties involving them. A particular emphasis will be put on the size-dependency of these properties by studying a range of materials from bulk Pt to single-atom catalysts.

title: Magnetic Excitations in Above-room-temperature Ferromagnetic van der Waals Material Fe3GaTe2

description: With weak interlayer coupling, van der Waals materials offer unique opportunities to utilize magnetism at the 2-D limit. Fe3GaTe2 has emerged as an attractive candidate for intrinsic ferromagnetic van der Waals (vdW) materials, exhibiting robust magnetism exceeding room temperature and showcasing high potential for applications in spintronics. The discovery of a significant two-dimensional (2-D) skyrmion topological Hall effect (THE), boasting an exceptionally wide temperature range encompassing room temperature, underscores the remarkable potential inherent in this material. We propose employing magnetic circular dichroic Resonant Inelastic X-ray Scattering (RIXS-MCD) at the Fe L3 edge on the ID-32 beamline to probe the ferromagnetic low-energy excitations in Fe3GaTe2. This approach holds the potential to provide invaluable insights into the contributions of spin and orbital degrees of freedom to 2-D magnetism and the magnetic Hamiltonian.
