title: IBS BAG

description: The IBS BAG includes in this proposal IBS teams and external groups from CEA-Cadarache (St Paul lez Durance) and IRBA (Brétigny-sur-Orge). We study structure-function relationships of proteins emphasizing in human health, biotechnology and methodology. Most of the projects are a continuation of the MX-2398 proposal and can be grouped into different topics as follows: host-pathogen interaction, new drug targets, fundamental cellular mechanisms, membrane proteins, biotechnological applications and methodology. Some of these projects use integrative approaches (X-ray crystallography, SAXS, NMR (and cryo-EM), together with other biophysical studies) with the aim to fully understand the complexity of the biological macromolecular systems on study.

title: ITABAG: 3D structures of macromolecules related to human health

description: The ITABAG includes structural biologists from Universities, the National Research Council and Hospital research centres in Italy. The laboratories take advantage of single crystal and small angle X-ray diffraction methods to study the structure-function relationships in various macromolecules. A unifying factor for the vast majority of the macromolecules under study is that they are related to human health, either directly, being human proteins involved in some disease, or indirectly, as proteins expressed by human pathogens and validated as potential pharmacological targets. Other projects investigate basic chemical processes, such as crystal growth, or aim at characterising macromolecules with potential biotechnological applications.

title: Multi-scale Multi-techniques investigations of Li-ion batteries: towards a European Battery Hub

description: In this science-driven Long-Term proposal, we propose a 3-years multi-beamline program tackling grand challenges for actual, emerging and future battery technologies. We will deploy advanced methodologies for accelerating research by setting new cooperation modes for multi-techniques multi-scale studies. Three chemistry-neutral scientific cases have been identified to fulfil this LTP: bulk-to-surface mechanisms, high energy system and smart sensing. Multiple, time-coordinated, interoperable spectroscopic, imaging & scattering techniques will be implemented. This proposal is the Pilot Phase towards a European Battery Hub aiming at accelerating workflows in battery research by optimizing the exceptional diversity of means available at ESRF. We expect to demonstrate the added value of a new “proposal” mechanism, e.g. science-driven beamtime allocation group, serving the fast growing, highly competitive and rapidly evolving European battery community.

title: Multiscale and multimodal characterization of polycrystal plasticity in metallic materials

description: This proposal will develop, and make available to the user community, a new experimental and algorithmic framework to conduct simulation informed multi-modal in situ experiments on metallic materials. This will allow to study the mechanical behaviour of polycrystalline samples at the microstructural scale (deformation, fracture). The establishment of automated acquisition and data processing pipelines will allow for the first time to use the feedback from experimentally driven simulations of the material response to guide subsequent “zoom-in” observations in selected regions of interest. Achieving this ambitious goal requires (i) a new, fully integrated, in situ load stage compatible with both id11 end stations (ii) an efficient data processing pipeline for DCT, topotomography and scanning-3DXRD acquisitions (both interactive & automated) and (iii) experimentally driven mechanical simulation routines to add stress/strain fields to the reconstructed data.

title: rheo-echo-XPCS to study the dynamic of the yielding transition in colloidal glasses

description: The yielding transition in glassy colloidal suspensions is a solid-to-fluid transition induced by shear. This transition has been studied with rheology yet its dynamics is not well characterized. Here, using rheo-echo-XPCS, we aim to perform series of oscillatory strain experiments at constant strain amplitude in stationary conditions and construct stroboscopically, every oscillatory period, the intermediate scattering function (ISF) using XPCS. The analysis of the echo-ISF yield the dynamics of the colloidal dispersion as a function of the strain amplitude and the wave vector q. We expect to better understand the mechanisms at play as we increase the strain amplitude and reach the yield strain γy. In particular, is there an α and β brelaxation that accelerate as we approach gy. Can the measured echo-ISF(q,γy,t) be mapped on the ISF function of supercooled colloids driven by the volume fraction Φ, ISF(q,Φ,dt). We will test hard sphere and fumed silica colloidal glasses.

title: Does bone around Ti implants structure itself as consequence of loading and surgical procedures? A SAXS/WAXS, XRF study of the peri-implant

description: Dental implants improve patients’ quality of life after a dental trauma. 5-10% of all implants fail in less than 10a for unknown reasons causing suffering for patients and high costs for society. An implant’s success rate is determined by the bone quality around the implant. While dentists possess tools to quantify the amount of bone, they lack precise knowledge about how drilling and loading influence the bone ultrastructure in the peri-implant zone. This proposal will characterize interfacial bone of clinical-sized Ti implants subjected to real-life loading conditions with multimodal high-spatial resolution scanning S/WAXS, XRF. By connecting ultrastructural findings with clinical parameters, we will bridge the gap between implant stability and underlying bone quality. Due to a statistically relevant set of sample conditions, we will be able to provide scientific-based guidelines on how drilling and loading protocols favour a rapid, strong, and long-lasting osseointegration.

title: Room temperature measurements on TiO2

description: We propose to investigate the role of orbital hybridization in the magnetism of TiO2 and single-atom doped (e.g. Fe, Co, and Ni) TiO2 using element selective HERFD XAS, XES, and resonant inelastic x-ray scattering (RIXS). The motivation of this work is to study the electronic structure of the single-atom doped TiO2. These measurements can uniquely determine whether the observed magnetization is due to a magnetic moment from one of the constituent elements, or their orbital hybridization.

title: DRIFT/XAS analysis of single-site Pt supported on UiO-66(Ce) for H2 production

description: In the panorama of H2 production strategies we are currently exploring the water gas shift (WGS) reaction over metal single sites supported on cerium-based UiO-66(Ce). We have recently prepared a Ce3+ rich UiO-66(Ce) catalyst with anchored Pt single sites. The catalyst presented similar catalytic activity than the conventional Pt/CeO2 catalyst at lower temperature (150 vs 50°C). Operando FT-IR and ex-situ Ce L3-edge XAS spectra unveiled a relation between the higher activity and hydrides/formate formation parallel to a higher Ce3+ content. We here propose to measure coupled DRIFT/XAFS spectra under operando conditions to obtain a solid comprehension of the electronic/structural/chemical interaction leading to higher catalytic properties of Pt/UiO-66(Ce) and disclosing the different reaction mechanisms over the two catalysts.

title: Liquid crystal topological defects at the nanoscale precision

description: We will study topological defects in smectic liquid crystals at the scale of a single defect or a very small number of defects, using nano-diffraction on a thin film (8CB smectic liquid crystal) made of topological defects oriented by a rubbed polymer substrate. The aim will be to study defect core structures and elastic distortions around the core at a scale that is still poorly understood for liquid crystal materials. We will also study how these structures evolve when approaching the transition to nematic phase or when nanoparticles are confined and organised within the core of these defects. We will scan in 1D, perpendicular to the oriented defects, both in GISAXS (reflection) and in TSAXS (transmission) to allow at each point for a full reconstruction of the smectic layer distortion and topological defects determination. Data analysis will take advantage of the methodology previously established in average, allowing for a future automatic analysis of the nanoscale 1D scanning.

title: SH0937488.09FU

description: UNITE provides a unified way for delimiting, identifying, communicating, and working with DNA-based Species Hypotheses (SH). All fungal ITS sequences in the international nucleotide sequence databases are clustered to approximately the species level by applying a set of dynamic distance values (<0.5 - 3.0%). All species hypotheses are given a unique, stable name in the form of a DOI, and their taxonomic and ecological annotations are verified through distributed, web-based third-party annotation efforts. SHs are connected to a taxon name and its classification as far as possible (phylum, class, order, etc.) by taking into account identifications for all sequences in the SH. An automatically or manually designated sequence is chosen to represent each such SH. These sequences are released (https://unite.ut.ee/repository.php) for use by the scientific community in, for example, local sequence similarity searches and next-generation sequencing analysis pipelines. The system and the data are updated automatically as the number of public fungal ITS sequences grows.

title: Microscopic dynamics of high-entropy metallic glass formers

description: In a recent experiment, we demonstrated that the glass and super-cooled liquid dynamics could be experimentally resolved while heating at a constant rate, thus extending the limitation of temperature due to crystallization and enabling the direct comparison with mechanical and calorimetric characterization. In this proposal, a set of alloys is selected comprising high-entropy and ‘conventional’ metallic glasses of three different compositional families: La20Ce20Y20Ni20Al20, Pd20Pt20Cu20Ni20P20 and Ti16.7Zr16.7Hf16.7Cu16.7Ni16.7Be16.7. The new temperature and time windows accessible by XPCS at ESRF-EBS will allow us to study, for the first time, the high-entropy effect on the microscopic dynamics of glass-forming melts. This will be a crucial experiment to check if there is an actual high entropy effect on the viscosity behavior of metallic melts.

title: Understanding the effects of manganese on reduction, reaction and dynamic behavior on catalytic activity of nickel-manganese spinel CO2 meth

description: Nickel-based spinel are stable, active and selective catalysts for the methanation of CO2, but their stability makes them difficult to activate. By adjusting the composition of such spinels, the reducibility at low temperatures is significantly increased. The methanation of CO2 using nickel spinels has not yet been studied under operando conditions to correlate the structural changes to the catalytic properties. Here, the influence of manganese on the reduction process and its role in the reaction will be investigated. First, investigate in EXAFS/XANES information on the evolution of the oxidation states and the local coordination environment of the metals (Ni and Mn) during reduction and catalysis. We couple it with XRD, to correlate these changes with accompanying changes in the long-range order of the material. These information will increase the understanding of properties required for highly active spinel catalysts in CO2 methanation and thus contributes to better catalysts.

title: Accurate in situ measurement of thermal expansion of pure zirconia and alumium titanate

description: The level of the local strains due to thermal loading in pure zirconia or aluminum titanate bulk materials is of few percent. Such very high values of elastic strains are due to phase transitions or anisotropy of the thermal expansion and they have a great influence on the thermomechanical properties of these materials. The determination of the stresses values associated to these strains require the knowledge of thermal expansion of stress-free crystals of the same phases. This is the aim of this proposal to determine these fundamental characteristics.
