title: Circadian regulation of synaptic output at a central oscillator network across scales using correlative fluorescence functional imaging, X-R

description: Animals adapt their behaviour across the day producing circadian rhythms. The physiological basis behind these rhythms have been extensively characterized in the fruit fly, where a network of ~150 neurons in its brain regulates the behavioural entrainment to the time of the day. To characterize the key peptidergic neurons from this central oscillatory network, we propose to interrogate in a correlated fashion on the same samples: 1) structural changes in the axon terminal arborizations involving the assembly and disassembly of synapses; 2) changes in the activity patterns reaching the synapses to trigger neurotransmitter release and 3) changes in synaptic vesicle distribution and abundance, across the time of the day. We will establish and demonstrate a correlative imaging workflow involving functional imaging of neuronal activity reaching the output synapses, X-ray tomography of sLNv fine morphology utilizing the ID16A beamline, and FIB-SEM interrogation of synaptic vesicles.

title: Operando studies of NiGa@GaOx catalysts for propane dehydrogenation

description: Operando XANES/EXAFS and XRD measurements on supported NiGa@GaOx catalysts are proposed to confirm the presence of metastable gallium hydrides (observed when feeding H2) as novel active centres during the propane dehydrogenation to propene reaction and which are suspected to significantly enhance the catalytic performance. In particular a combined edge measurement will help to determine the coexistence of a NiGa phase with a GaOx phase at elevated/operational temperatures under reaction conditions to understand the significance of this multi-phase composition on performance.

title: Structural bases of striated muscle contraction

description: Muscle contraction is regulated by both Ca2+ dependent thin filament activation and mechanosensing-based thick filament activation. Evidence is growing for the involvement in thick filament regulation of the cytoskeleton protein titin, which runs from the midpoint of the thick filament to the end of the sarcomere, and the myosin binding protein C (MyBP-C), which is bound to the backbone of the thick filament in the central one-third of either half filament and bridges thin and thick filaments. We use X-ray diffraction to investigate MyBP-C role in inter-filament communication and titin role in thick filament mechanosensing. The experiments, conducted in intact frog skeletal muscle fibres, exploit the finding that X-ray fine structure of myosin based reflections reports the footprints of both MyBP-C and titin and represent a testbed for future investigation on skinned fibres and whole muscles of rodent models with mutations in specific proteins.

title: Nanostructure of a strain-induced charge-density wave in a 2D quantum material

description: In this experiment, we will study a strained-induced orientational transition of a charge-density-wave (CDW) that we recently evidenced in TbTe3, a nearly-tetragonal 2D van der Waals material. In the pristine state, the CDW is oriented along the in-plane c axis, and under tensile strain along the perpendicular in-plane direction a, the CDW disappears along c while it appears along a. We showed that this transition is directly related to the ratio of the in-plane lattice constants a/c, and takes place when a=c. However, the way the CDW along a appears still has to be elucidated. In particular, it could appear through the nucleation of domains. The aim of this experiment is to check this scenario using a nanobeam. If domains appear, we will study their evolution under strain. If not, we will validate a scenario of spatially-coexisting CDW. We will additionally get a spatially-resolved measurement of CDW q-vectors under strain, and study the role of temperature.

title: Operando X-Ray absorption spectroscopy for the study of well-defined Cu nanocrystals in the nitrate electroreduction reaction

description: The electrochemical nitrate reduction reaction (NO3RR) is a promising approach for the conversion of nitrate contaminants into ammonia (NH3), a desirable chemical nowadays produced with the energy-intensive Haber Bosch process. Cu remains one of the most effective catalysts for NO3RR, however, its NH3 selectivity and production rate are still limited. The fundamental reactivity/structure/composition relationships need further elucidation to move the field forward. Herein, we study the impact of size, shape and composition of Cu catalysts in NO3RR using a library of well-defined and shaped tunable Cu and Cu oxide nanocrystals. These catalysts exhibit different performance, which needs to be explained considering their status during operation. This proposal aims at using operando X-Ray absorption spectroscopy (XAS) to follow dynamic changes in coordination environment and oxidation state of Cu under NO3RR

title: Investigation of intracellular speciation of a series organometallic hemilabile gold(III) complexes

description: Chelating carbene-pyridine based organogold(III) complexes of general formula [(C^C)Au(C^N)]+ present antiproliferative activities from the low micromolar to the submicromolar range. Their mechanism of action is currently being investigated as they are potential anti-cancer agents. We observed a clearly different chemical reactivity and cytotoxicity among members of this family, which was related to the nature of the carbene and the N-donor ligands. We previously demonstrated the possibility to identify the speciation of gold(III) phosphine complexes by cryo-X-Ray Absorption Spectroscopy on beamline BM16[2, 3]. We now apply for beamtime on BM16 to perform cryo-XAS measurements on cancer cells treated with three different [(C^C)Au(C^N)]+ complexes to draw relationships between intracellular speciation, anticancer properties and chemical reactivity. This project is financially supported by ITMO Cancer (project Goldspec no. 23CP039-00).

title: Unconventional current-driven magnetization reversal detected by resonant x-ray magnetic scattering

description: This experiment will continue our recent successful experiments on XMaS, aiming to clarify the novel current-driven magnetization switching which we have recently observed in CoFeTaB/Pt ultra-thin film bilayers, where the magnetization in CoFeTaB appears to twist into a stable nanometer-scale 'exchange-spring' configuration close to the interface. We will detect the proximity induced magnetization in Pt, which arises close to the interface with ferromagnetic CoFeTaB, using the element-specificity of resonant x-ray magnetic scattering, and use this to track the interface magnetization in CoFeTaB during field- and current-driven magnetization reversal. This will enable us to unambiguously determine how the current drives energy-efficient interfacial magnetization reversal in this system. We will also begin to look at Ta within the CoFeTaB layer; the distribution of Ta modifies local exchange interaction, and may explain how the exchange-spring state is able to form in such a thin film.

title: Unlocking Salty Secrets: Cellular Ion Profiling of Rice

description: Climate change-induced lower and irregular rainfall, along with high evapotranspiration rates, contribute to soil salinization. This leads to reduced plant growth and yield losses, with rice (Oryza sativa), a staple crop, being particularly sensitive to salinization compared to other cereals. Developing resilient rice varieties is therefore imperative. Na+ transport and allocation are crucial in salt stress tolerance, with High-affinity K+ Transporter proteins (HKTs) playing a key role. Current methods to detect Na+ toxicity in plants, like inductively coupled plasma-mass-spectrometry, are destructive and lack a comprehensive Na+ profile at the cellular level, limiting our understanding of Na+ allocation across tissues. This project aims to profile Na+ at the cellular level in different rice varieties and also generate elemental profiles for Cl- and K+ to enhance our understanding of salinity responses.

title: Disclosing Ce-In synergy and VO dynamic by XAS/XRD study on MOF-derived In2O3/CeZrOx catalyst for CO2-to-CH3OH conversion

description: In the race towards CO2 emission reduction, its conversion to methanol is of great interest due to the latter market potential as valuable chemical. Oxide-supported metal catalysts have been widely applied in methanol synthesis and extensively studied for decades. To improve control over the dispersion of catalytic active sites, we have developed a strategy involving thermal decomposition of metal-supported Ce/Zr-based Metal-Organic Frameworks (MOFs) to prepare In2O3 catalyst supported on different CeO2-ZrO2 solid solutions. We here propose to combine quasi-simultaneous XAS/PXRD measurements under reaction relevant conditions (10 bar of CO2:H2 (1:3), 573K) at BM23 to disclose the activation/deactivation mechanisms related to In and Ce reduction and particles agglomeration. Moreover, to track active and transient active species kinetics, we will apply Modulated Excitation of reactants on isolated XAS and PXRD experiments which we successfully already employed previously.

title: RIXS characterization of sub-stoichiometric tungsten oxide films for transparent electric contacts

description: We propose employing RIXS characterization to qualify the electronic structure of sub-stoichiometric WO3-x thin films, in view of applications such as transparent electric contacts. Oxygen-deficient WO3-x exhibits high electrical conductivity, concurrently it displays enhanced optical absorption within the visible-to-NIR energy range, which poses challenges for optimal applications. We aim to verify the hypothesis that this enhanced optical absorption arises from d-d excitations within the W 5d states, facilitated by the increased nominal electronic configurations of 5d1 and 5d2 as a result of self-doping. Once our research results verify the hypothesis, they will yield a comprehensive understanding of the underlying mechanisms driving the enhanced optical absorption, thereby providing insights to mitigate this effect, and contributing to advance the utilization of WO3-x as transparent electric contacts.

title: Development of a laser-driven dynamic compression platform on ID09 to perform ps time resolved X-ray diffraction pump probe experiments at h

description: This LTP aims at setting a laser-driven dynamic compression platform on ID09 in order to perform ps time resolved X-ray diffraction pump probe experiments at high pressure. A 5J laser driver and a point VISAR/PDV diagnostic will be provided to generate the shock compression in materials and characterize their thermodynamic states by velocimetry measurements. With this new high power laser system, pressures in the 100 GPa range could then be generated, an order of magnitude higher than what can be presently achieved on ID09. Over the three years of the LTP, this dynamic compression platform will be mounted, interfaced with the synchrotron beam, tested and made user friendly so that other groups interested by Xray structural studies of matter under dynamical compression could use it. It seems a necessary step to aggregate a community able to make the scientific case for building an XRD station near the High Power Laser Facility (HPLF) of ESRF in the near future.

title: Tuning Pt d-band states for highly performing propane dehydrogenation catalysts

description: Direct propane dehydrogenation (PDH) has emerged as one of the most promising approaches to produce propylene. Pt is a commercially used metal for PDH and Sn is the most commonly used promoter for Pt catalysts. The PDH reaction requires the activation of the C-H bond, meaning its kinetics depend on the electronic structure of the Pt. However, the energy levels of the d-states in Pt and Pt-containing alloys, which play a crucial role in directing bond formation, have rarely been directly measured experimentally. We have developed PtSn loaded Al2O3 catalysts with various Pt:Sn ratio, which showed very different propylene formation rate and deactivation rate. Here we apply for the Pt L3 edge RIXS study to measure the d-band of Pt and Pt-C bond strength after H2 activation, propane dehydrogenation and regeneration. Compared with different Pt:Sn ratio will determine the optimal electronic structure of Pt, providing fundamental descriptor in C-H activation.

title: Investigation of the electronic properties of CeRu2 by X-ray absorption spectroscopy and circular magnetic dichroism

description: CeRu2 is a superconductor of type 2 (critical temperature at 6.2 K) with a peculiar electronic structure. In order to shed some light on these exotic properties of CeRu2, we propose to analyze the Ce-L2,3 absorption edges by X-ray Absorption Spectroscopy (XAS) and X-ray Magnetic Circular Dichroism (XMCD), which probe the Ce 5d electrons. The latter contribute to the metallic bond and are highly sensitive to the electronic structure. We propose to evidence a possible modification of the hybridization of the 4f electrons when going through the critical temperature on the ID12 beamline.

title: Growth and structure of Cu doped TiO2 on LAO(001)

description: Magnetic semiconducting thin films with remanence at room temperature are of primary importance for spintronic applications. We plan to realize one of such films by MBE, doping with copper TiO2 anatase films grown in epitaxy on LaAlO3(001). We will use in situ non-resonant and resonant x-ray diffraction (RXRD) at the Cu K edge to study the films structure.With RXRD we want to determine if Cu is in substitutional sites and on which ones.
