title: Insights into Polyphospahte granules: CryoSTEM validation and arsenate bioremediation potential

description: Bacteria store polymers of inorganic polyphosphate (PolyP) in granules. Our research aims to unveil the PolyP nano-compartments, in radiation-resistant Deinococcus radiodurans (Dr), which are crucial for its stress response, containing metals such as K, Ca, and Mn, as confirmed by X-ray fluorescence imaging (XRF). Cryo-STEM-EDX analyses validated previous XRF results, revealing high P concentration and other metals like K, Na, and Mg. However, signals for Ca, Mn, and Fe were undetectable. Deinococcus indicus, exhibits radiation resistance and tolerance to high arsenic concentrations. Given the chemical similarities between arsenate and phosphate, we hypothesize that arsenate may be store in the nano-compartments, suggesting potential bioremediation applications. Given the growing interest in CryoEM, our proposal is essential for CryoSTEM-EDX validation, ensuring a comprehensive comparison with XRF. Additionally, it explores the potential of nano-compartments for As bioremediation.

title: Deciphering the origin of exceptional vanadium enrichment during lateritic weathering using XAS

description: Lateritic profiles from Suriname and Austalia may be strongly enriched in V, with V contents up to 3750 mg/kg in the most strongly weathered units. The elucidation of the evolution of V solid speciation is necessary to fully understand the processes governing exceptional enrichments in laterites , and more broadly the dynamics of V during weathering. Moreover, to predict V solubility, bioavailability, and therefore, toxicity, solid speciation determination is required, as well as redox state. The vanadium K-edge (5465 eV) is informative, and in this experiment, we propose to focus on bulk and spatially resolved XANES measurement. In that frame, we propose to accurately identify the evolution of V redox states and solid speciation in a selection of samples using X-ray absorption spectroscopy.

title: Controlled orientation and order of nanorod assemblies confined within liquid crystal topological defects

description: We will study the structure of nanorod assemblies confined within smectic grain boundary topological defects. We have shown that these nanorod assemblies present well-defined order and orientation everywhere on a given sample leading to anisotropic optical properties. However, in order to take full profit of these properties but also in a more fundamental perspective, to understand in depth the anisotropy that can be reached for the optical properties of nanorods arrays, it is important to fully control the structure of these nanorod arrays. We will thus determine the order and orientation of various nanorod assemblies as a function of nanorod size and of nature of the ligands grafted around the nanorods that may be coupled to the smectic layers below the nanorod assemblies. We will study the impact of the liquid crystal structural variations as a function of thickness. We will then build a model of the coupling between nanorods assemblies and smectic defects.

title: Immobilization of Th(IV) in Yttrium Stabilized Zirconia Ceramics

description: Safe disposal of nuclear waste requires matrix materials with strong resistance against corrosion and dissolution over a period of more than 10E6 years. Zirconium based ceramics might be used as storage material, because their natural analogues zircon, ZrSiO4, and zirconia, ZrO2, are known to remain stable in geological cycles up to approximately 2·10E9 years. We intend to investigate the structural substitution of thorium in Y-stabilized ZrO2 ceramics. Th(IV) is selected for this study because it represents the typical oxidation state IV which appear in Pu, U and Th containing nuclear waste. The aim of this study is to determine to what extend Th(IV) can be introduced into zirconium ceramics without Zr/Th phase separation.

title: Residual stress field in multimaterial ceramic bone scaffolds obtained through VPP 3D printing technology

description: Ceramic materials like zirconia and alumina are becoming more and more important in the biomedical area. With the development of 3D printing techniques, as vat photopolymerization (VPP), the design and manufacturing of complex geometries for Bone Tissue Engineering (BTE) scaffolds became possible. Multilayer geometries have been proposed to increase toughness, slow crack propagation and improve reliability. The study of the residual stresses in 3D layered geometries is difficult to be predicted by analytical models and few experimental tests have been conducted to analyse the stress profile. Employing the X-ray Synchrotron Diffraction, and particularly the Laue microdiffraction, it’s possible to evaluate the superficial stress profile for a depth up to hundreds of micrometres. The experimentally obtained stress data can be used to validate numerical models which predicts the residual stresses in complex geometries and assess the overall apparent toughness of layered 3D BTE scaffolds.

title: X-RAY REFLECTIVITY STUDY OF GRAPHENE OXIDE ASSEMBLY AT THE AIR-LIUQID INTERFACE

description: The current proposal focuses on characterizing the behavior of pristine and modified graphene oxide (GO) nanoflakes at the air-liquid interface. A thin GO layer can be effectively utilized in applications such as transparent conductors, sensors, et al. Langmuir-Blodgett (LB) is a widely used technique for thin film deposition. However, conventional LB deposition often results in the folding and overlapping of GO nanosheets before achieving continuous layers. This effect is influenced by edge-to-edge negatively charged interactions of GO nanoflakes, governed by the presence of ionized carboxylic acid groups. Carboxylic groups can be employed to modify GO nanoflakes with amino molecules, altering charge and van der Waals interactions. The proposal aims to use XRR and GIWAXS techniques to study GO assembly at the air-liquid interface. The results will help determine the composition of modified or reduced GO nanoflakes and experimental conditions for defect-free layer formation.

title: Structural changes in the myofilaments during the heartbeat: a whole organ approach

description: Cardiovascular disease continues to be the leading cause of death worldwide, and current efforts to develop better therapeutics for heart failure have been held back by limited understanding of the normal control of contraction on the timescale of the heartbeat. Here we will use time-resolved ultra-small and small-angle X-ray diffraction at ID02 on whole beating hearts isolated from the rat to determine the relationship between the mechanical function, changes in the structural unit of striated muscle, the sarcomere, and the associated dynamic structural changes in the constituent myosin and actin filaments in situ.

title: 4D Micromechanical investigation of fatigue crack nucleation mechanisms in a polycrystalline nickel superalloy.

description: This works aims at understanding the interaction between microstructure, plasticity and fatigue damage in the nickel-based superalloy Inconel 718, by coupling several in-situ 3D characterisations techniques. The combination of Diffraction Contrast Tomography (DCT and 3D-XRD), Phase Contrast Tomography (PCT) and Topotomography (TT) are used to characterise the polycrystalline microstructure (DCT), the in-situ evolution of deformation heterogeneities (3D-XRD, TT) and damage (PCT) in micro-tensile specimens under fatigue loading. In-situ experiments at ESRF will be carried out with the NANOX test rig, specifically designed for high cycle fatigue testing on beamline ID11. A specific objective of this work will be to correlate the microstructure and the intragranular elastic and plastic deformations, to the onset of fatigue damage, with the aim of significantly improving the understanding of fatigue crack nucleation mechanisms.

title: in situ photon-in-photon-out spectroscopic studies with high temporal, spatial and energy resolution during emergence of transition metal su

description: Today’s emerging questions in colloidal science go far beyond the precise control of size. The synthetic and theoretical efforts focus on a wide range of nanomaterials with unique electronic properties as they carry on a potential to have impact on highly relevant societal themes ranging from electronic devices, energy conversion to energy storage. The particularly important recent examples include the transition metalchalcogenides (TMS), and nitrides (TMN). In this context studying the electronic structure of the central metal atom and differentiating between various metal ligands during synthesis has become of paramount importance for the chemistry of materials.
The new high-energy resolution emission spectrometers (microXES and tender) at ESRF enable in situ XES experiments with high energy, time and spatial resolution. However, what is missing is a dedicated sample environment for on-line monitoring of the syntheses of nanostructure in solution at the relevant conditions.

title: Detoxification of methylmecury in emperor penguins

description: We propose to study how emperor penguins (Aptenodytes forsteri) from Antarctica1 detoxify methylmercury and the species of Hg transferred to chick embryos. The identity and proportions of Hg species will be obtained using Hg L3-edge HERFD-XANES spectroscopy, and their isotopic signature will be obtained by inverting the Hg speciation and the 202Hg and 198Hg isotopic data. Results will allow us to assess the risk from Se deficiency caused by Hg poisoning in adults and through Hg transfer to chick embryos.

title: Strain-induced changes on the RIXS spectrum of nickelate thin film

description: Infinite-layer nickelates are materials of increasing interest to the RIXS community. The presence of unconventional superconductivity on the thin films makes these materials 2D analogs of the cuprates. However, important differences exist, one of them being the layer interface proximity properties, which can result, for example, in different substrate-induced strains. The understanding of these properties can lead to material design for applications, by manipulating layers and proximity effects. For this experiment, we will use the Razorbill Ultraminiature UHV strain cell on the measurement of the spectroscopic signatures of Ni L3 edge for a PrNiO2 (PNO) thin film, focusing on the strain dependency of dd excitation and magnon. We will apply ex-situ strain and perform momentum, high symmetry direction, and strain dependency studies.

title: Laser-driven shock wave generation in the iron samples with the temperature control

description: Laser-induced shock wave generation is a key technique for investigating phase transitions in various materials within the ultrafast (sub-nanosecond) regime. Despite the drive laser pulse duration extending to several nanoseconds (6.3 ns in our experiments), the resulting shock wave front remains sharply defined. This precision enables detailed observation of the time-dependent phase transition hysteresis. By controlling the initial sample temperature (using the newly developed sample chamber at ID09), we can systematically study different phase transitions within the same material. This approach significantly enhances our understanding of the fundamental physics governing these dynamic processes.

title: Operando XAS and XRD measurements to elucidate the deactivation / reactivation behaviour of Pt-Pd/CeO2 bimetallic catalysts for CH4 oxidatio

description: This study aims at the fundamental understanding of the deactivation/recativation behaviour of Pt-Pd/CeO2 catalysts for CH4 oxidation. Such bimetallic catalysts are typically used for emission reduction in the exhaust of heat and power plants but the fundamental understanding of their evolution under reaction conditions is still lacking. This is caused partially by the rather heterogeneous catalyst structure obtained by conventional preparation methods. Starting with well-defined and alloyed Pt-Pd NPs of different sizes, the evolution of each noble metal will be monitored by in situ/operando XAS at Pt L3 and Pd K edges and XRD measurements while exposing the catalysts to progressively higher temperatures. This will help to identify segregation and de-alloying processes as well as the formation of highly dispersed Pt and Pd species, which lead to catalyst deactivation. In a next step, the re-alloying process will be investigated as a function of catalyst reactivation conditions.

title: Optical imaging and single-cell RNA sequencing  reveal individual heterogeneity in pancreatic cells that supports global function

description: Our study investigated the heterogeneity in glucose-induced excitability within islet cells, providing a cellular basis for their roles in glucose-responsive hormone secretion. To comprehensively map glucose-induced excitability profiles, we developed SHIMMER, a high-throughput, multimodal data acquisition platform that integrates electrical signals, Ca2+ fluxes, and single-cell sequencing data. By quantifying the non-stationary electrical and calcium signal dynamics, we formulated a machine learning-based electro-calcium model that shows how variations in membrane conductance and Ca2+ clearance contribute to increased heterogeneity in cytosolic Ca2+ accumulation. Using SHIMMER for single-cell sequencing on representative cells, we identified several genes that associated with electro-calcium characteristics, and found a potential marker for a highly excitable cell subpopulation. These findings indicate that islet cells tend to exhibit a large heterogeneity in glucose-induced excitability, being essential for their normal functioning.
