title: Growth strategies of apex predators from the Late Triassic of South Africa.

description: This proposal seeks to understand the growth and anatomy of four new species of early-branching theropod dinosaurs from South Africa. We propose high-resolution scans of skull and limb bones of this new material, suitable for anatomical reconstruction and digital osteohistology. The resulting data will be used to test the position of these new species on the tree of theropod evolution and understand their growth strategies and physiology. These lines of enquiry will address a major palaeontological question, namely, why theropod dinosaurs became the apex predators of the late Mesozoic, replacing other incumbent carnivorous lineages after the end-Triassic mass extinction. The material examined here represents the first theropod species from the Triassic of southern Africa. The uniqueness of these specimens, the difficulty in obtaining segmentable CT images, and the high resolutions required for digital osteohistology, require use of non-destructive synchrotron microtomography.

title: Structural mechanisms of multi-layered cellulosic/collagen/UV-cured polymers nanocomposites under uniaxial extension or compression, probed

description: The aim of this project is to understand the structural mechanisms evolutions of developed multi-layered cellulosic/collagen/UV-cured nanocomposites during uniaxial extension or compression. Original structuring of UV-curable polyethylene glycol diacrylate (PEGDA) / cellulose nanocrystals (CNC) have been recently discovered thanks to novel processing methods combining frontal ultrafiltration (FU) ultrasound (US) and UV-curing. The first structuring by FU / UV-curing consisted of two sub-layered organization from nematic to cholesteric. The second structuring obtained by FU / US / UV-curing is a three sub-layered orthotropic organization mimicking the articular cartilage (parallel, isotropic and perpendicular) orientation of the CNCs. The goal of this proposal is to understand the reliable mechanisms of deformation / fracture toughness / delamination of multi-layered organization and structural reorganization of nano-particles inside and at the interface of the sublayered.

title: Compression failure of Sustainable Natural fibre Composites

description: Natural fibre-reinforced polymer composites will play a crucial role in meeting NetZero requirements as they combine environmental sustainability with excellent mechanical properties at low weight. Despite their advantages, such composites exhibit poor performance under compressive loading due to issues like fibre kinking. Our focus turns to understanding the behaviour of kinking during compressive failure. This requires high frame rate imaging, as catastrophic kink band initiation occurs quickly. To capture this event with the necessary high spatial resolution, we propose in-situ compression on ID19. In this beamtime, we aim to understand the compressive performance of newly developed flax fibre reinforced polymer (FFRP) composites, in which the epoxy resin is made of renewable resources, the so-called ‘greenpoxy’. This work will lead to new designs to improve their compressive performance by suppressing kinking band formation.

title: Combined nanoscale strain and halide composition mapping in perovskite layers deposited on silicon for tandem solar cells.

description: This proposal concerns the very promising technology of tandem solar cells where hybrid halide perovskites (HHP) are used as an active layer on top of a silicon cell. Our aim is to simultaneously map, using the ID13 nano-beam, the strain, lattice orientation and halide distribution by combining XRD and XRF in pristine and aged samples. This will allow to gain fundamental insights into aging mechanisms of HHP films. After a first successful experiment in June 2023, we apply for a follow-up experiment. Samples obtained from two different deposition methods as well as films deposited on different substrates will be studied and compared. The microstructure of all above samples will be investigated in the sample plane. A second focus concerns the study of cross section samples of solar cells prepared in different conditions, in the perspective of depth-resolved studies of the HHP microstructure and halide composition

title: Coupling oxidation state and catalyst stability during pulsed electrochemical CO2 reduction via operando X-ray absorption spectroscopy

description: Electrochemical CO2 reduction (eCO2R) is a promising pathway to convert detrimental CO2 emissions into sustainable chemicals. The use of gas diffusion electrodes (GDEs) fed by gaseous CO2 enables achieving high activity and selectivity, albeit with limited stability. We recently demonstrated by operando wide-angle X-rays scattering that, during continuous electrolysis, (bi)carbonate crystals precipitate close to the catalyst, causing GDE instability. Strikingly, preliminary pulsed electrolysis experiments show that (bi)carbonate precipitation can take place without losses of GDE selectivity, leading to a 10-fold increase in GDE stability. As the catalyst can oxidize during the pulses, we propose to use operando X-rays absorption spectroscopy to investigate the role of catalyst oxidation state in controlling GDE selectivity and stability during pulsed electrolysis, as this holds the key to stable eCO2R.

title: Coupling diffraction and tomography to shed light on the formation of sulphide inclusions in natural diamonds

description: Being pristine samples from depths that we cannot reach, mineral inclusions in natural diamond have attracted much interest for their potential to shed light on the composition of the Earth interior and the process of diamond formation. Sulphide inclusions are very common and have been studied to understand the occurrence of sulphur and chalcophile elements in the mantle. Sulphide inclusions are still studied mostly ex situ, employing destructive techniques that necessarily cause the loss of information regarding the relationship between the host and the inclusion, and often risk to provide only a partial sampling of the inclusions. Thus, we propose to couple diffraction and tomography to characterize the inclusions without breaking the diamond host. This approach will allow us to identify the phases entrapped in the inclusions, evaluate their morphology and orientation, to get insight into the growth environment and on the time of formation of host-inclusion pair.

title: Liquid-phase High-Pressure Synthesis of New Metal Silicide Electrocatalysts for H2 Production

description: This proposal aims to investigate the Fe/Ni-Si system under high pressures (HP) to discover new materials for efficient H2 production via water splitting. While room pressure Ni/Fe silicides have shown remarkable electrocatalytic properties, our intention is to exploit the rich structural diversity of these materials under HP to synthesize novel HP metal silicides of high interest for electrocatalysis. We will firstly search for the HP CsCl-type structures of FeSi and NiSi, and then explore the ternary Fe-Ni-Si system. To do so, we will perform syntheses in molten salts using a Paris-Edinburgh (PE) press. In situ X-Ray diffraction will be crucial to monitor phase reactions and structural transformations induced in molten salts under pressures ranging from 2 to 10 GPa and temperatures from 500°C to 2000°C. This endeavor aims to identify intermediates and final products, recoverable due to the large volume press.

title: Impact of PY-IT polymer acceptor third-component and of GOPS-doped PEDOT:PSS interfacial layer on the structural properties of a photoactive

description: We aim to investigate the structural properties of new blend active layers with polymer acceptors composing stretchable organic solar cells, as
well as the impact of intermediate layers and electrodes on the mechanical behavior of the whole stacks. We will study binary and ternary polymer blend
behaviour in multilayers and devices for outdoor applications, and we will focus on the relationship between the evolution of crystallinity, the mechanical
and the electrical behavior of semi-conducting polymer thin layers, buffer layers (PEDOT:PSS, ZnO) and solar cell stacks during mechanical loading. The
structural properties of the individual materials as well as their properties when incorporated in a device stack will be investigated by in situ
grazing incidence X-ray diffraction under applied uniaxial tensile stretching. The structural behavior will be linked to the electronic properties of
the layers and the entire cell, in order to figure out more stretchresilient flexible devices.

title: Copper speciation in lustre layers

description: Lustre is a metal-glass nanocomposite layer consisting of metallic silver and/or copper nanoparticles in a glass matrix, located at the outermost surface at a depth between 40 nm and 200 nm and with a thickness from ~ 100 nm to 5 µm. It was obtained by a process of ionic exchange between the alkali ions of the glass and silver and copper ions from a precursor applied to the glass surface. The concentration and distribution of these nanoparticles, as well as the presence of ionic copper and silver species, contribute to the different optical properties of the lustre layer, such as colour and gloss. The optical properties depend on the materials and the production process (technology) and provide historical information about different production centres. It is essential to analyse cross sections of the decorations by XRF and XANES with submicron resolution to determine the distribution of metallic and ionic species and to establish correlations between them and lustre technology.

title: Arsenic speciation and toxicity in upcoming European lithium (Li) mines unveiled by (µ)-XAS

description: As lithium (Li) plays a critical role in Li-ion batteries powering electric mobility, Europe's dependence on external Li sources prompts initiatives to establish domestic production. Two mines in Portugal and Finland aim to commence exploitation of Li-rich pegmatites by 2025, enhancing Europe's Li supply security. However, environmental risks linked to Li extraction from hard rock resources remain unexplored, despite noted high arsenic (As) concentrations in tailings from pilot studies at these mines. Given the intricate mineralogy of As in these lithologies and its significant impact on mobility, spatially-resolved and bulk X-ray absorption spectroscopy (XAS) at the As K-edge will be used to quantitatively determine the As speciation in these tailings. Furthermore, we will investigate the mineralogical origin of As mobility by comparing our leaching test results to the solid As speciation in leaching residues at different stages of Li recovery in relation to waste management options.

title: Characterizing the origin of organic selenium in seleniferous soil of Punjab, India

description: Occurrences of seleniferous soil and associated selenium (Se) toxicities to plants, animals, and humans are environmental concerns in Punjab, India. These Se toxicities are attributed to the high Se uptake and accumulation in edible plants. Our two experiments at the FAME-UHD beamline investigated the temporal dynamics of Se speciation in the topsoil and different parts of the rice and wheat plants over a rice-wheat crop rotation season in a seleniferous agriculture plot, where rice crop residue had been incorporated for four years. Results showed that organic Se is the dominant Se reservoir in this soil, and plants primarily uptake Se from the soil as organic Se. However, the origin of this organic Se in soil could not be identified conclusively due to the limited number of sample analyses. Therefore, we propose further beamtime at the FAME-UHD beamline for the speciation of Se in additional soil samples.

title: Ambiguity in the crystal chemistry and dissolution kinetics of doped uranium dioxide nuclear fuels

description: Nuclear fuel, composed of UO2, has a complex chemistry and fuel manufacturers are increasingly interested in adding dopants that improve the performance within a nuclear reactor. The introduction of these dopants into the UO2 system can intrinsically alter the crystal chemistry and local speciation of the system, which in turn influences the oxidation behaviour. This may have negative consequences on the aqueous corrosion of the U-O system and therefore influence the safety of spent nuclear fuel in a geological disposal facility. In this proposal, we aim to understand the influence of metal dopants (Al, Cr, Ti) on the local structure, speciation and radiolytic dissolution of [001]-oriented UO2 single crystal thin films.We will systematically understand the local structure and speciation of U and metal dopants as a function of dopant type and concentration (HERFD-XANES), and we will quantify the dissolution of these materials through in-situ corrosion experiments performed using XRD.

title: Experimental study of the P-T stability of phlogopite in metasomatised peridotite with varying H2O contents in the deep cratonic lithosphere

description: Phlogopite is an important metasomatic, hydrous, potassic phase in peridotite from on- and off-cratonic lithospheric mantle. It is significant in the petrogenesis of mantle-derived magmas, including micaceous kimberlites, ultramafic lamprophyres, kamafugites, lamproites, which are all potential sources of diamonds.

We lack experimental investigations close to the limits of phlogopite stability in a model mantle composition enriched in K with varying amounts of H2O from 4 to 9 GPa (120 to 300 km). Variations in the %H2O available determine the shape and location of the solidus, and hence the onset of partial melting of a K-enriched mantle.

The study will determine the stability fields of phlogopite in the Earth upper mantle as a function of P, T, and bulk %H2O, using the large volume press at ID06 in combination with in-situ XRD.

The study will contribute to more complete modelling of the lithosphere-asthenosphere boundary of a metasomatised mantle enriched in K and H2O.

title: Q-dependence of the fast secondary relaxation in metallic glass-formers during the liquid-to-glass transition

description: During a recent XPCS beamtime at DESY we probed the dynamical response of a metallic glass (MG) of Zr46.8Ti8.2Cu7.5Ni10Be27.5 (vit4) and we obtained the first experimental evidence of a fast secondary beta-relaxation process in a glass, prior to the main structural relaxation which results in a double decay of the intermediate scattering functions (ISFs) in the ms time scale. Due to the low signal to noise ratio available at low Qs and short times scales, we could not characterize neither the wave-vector dependence of the beta-relaxation nor its evolution with temperature. For this purpose, we propose here to use the large coherent flux offered by XPCS at ESRF-EBS to probe for the first time the temporal evolution of the beta-relaxation in a MG across the glass-transition temperature. A successful experiment will deepen our understanding on the glassy dynamics from an extended scale and may unveil the physical origin for the recently reported string-like atomic motions in MGs.

title: Photoregulation of G-quadruplex DNA by non-covalent azobenzene photoswitches

description: G-quadruplexes (G4) are non-canonical DNA structures involved in important cellular regulatory functions in various genomes, correlated with their folding mechanism. Therefore, the design of small ligands capable of modulating G4 formation/stabilization is of growing interest for the development of new anticancer therapies. In this context, the reversible control of G4s using bistable photoswitches offers promising prospects for applications in photopharmacology but remains largely unexploited. The present project aims to characterize the dynamics of structural changes in G4s triggered by a functionalized azobenzene photoswitch (AZO1), using time-resolved solution X-ray scattering (TR-XSS), an ideal probe to capture changes in DNA 3D conformation. While the properties of AZO1/G4 complexes have been characterized at equilibrium, TR-XSS studies will provide crucial information on non-equilibrium DNA structural changes that will serve as a benchmark for optimization of G4 photoswitches.

title: Study of inversion symmetry breaking in a ferroelectric/insulating K0.5Na0.5NbO3/SrTiO3 2DEG

description: First principle calculations predict the formation of a 2D-electron gas (2DEG) at the (001) interface between SrO-terminated SrTiO3 and ferroelectric (FE) KNN, which has the peculiar property to be on/off switchable by the direction of the KNN FE-polarization. This is very promising in view of non-volatile electronic applications. Recently we were able to realize such 2DEG by a epitaxial engeneering.
We propose total electron yield x-ray absorption spectroscopy and x-ray linear dichroism at the Ti L3,2 and Nb M3,2 -edges to establish the oxidation state and the crystal-field splitting of the Ferroelectric/insulator 2DEG formed at the KNN/STO interface. The results will provide crucial details concerning the electronic properties of the system, including the crystal field splitting and valence of Nb-4d and Ti-3d states, the latter possibly giving clues about the filling of Nb-related and Ti-related bands contributing to the 2DEG.
