title: A new microscopy of atomic motion in nanostructures

description: We propose to develop a new method to obtain direct space images, with ~30 nm resolution, of the atomic motion in GaN nanostructures. This new microscopy is based on the combination of Coherent Diffraction Imaging (to obtain direct space images) and resonant elastic scattering at forbidden reflections, which provides sensitivity to atomic motion, and is becoming possible thanks to the extreme brilliance of the new source. After a very promising first experiment, we would like to continue our investigation GaN nanopillars, where free surfaces, strain, crystal defects and inversion domain boundaries are expected to cause inhomogeneities of the atomic thermal motion. A first real space image was obtained by CDI at a forbidden reflection at room temperature. More time is requested to repeat the measurement at high temperature, to enhance the relative contribution of atomic thermal motion over the intrinsic local anisotropy of the crystal structure.

title: In situ photon-in photon-out spectroscopy measurements on ultra-small Cu3N nanoparticles

description: We propose to investigate the reaction kinetics, nucleation, and formation of ultrasmall Cu3N nanoparticles by one-pot solvothermal controlled synthesis using photon-in photon-out x-ray spectroscopy. The motivation of this work is to monitor the changes in the electronic structure during the reduction of Cu(II)methoxide to Cu(I) by benzylamine and consecutive transformation to Cu3N. The unique combination of both XES and XAS applied under realistic reaction condition will explain the nature and changes in the ligand/species around absorbed atom.

title: Biophotonic materials with varying degrees of order

description: The bright colors of many organisms such as butterflies and beetles originate from complex 3D dielectric nano-structures. Interestingly, despite their beautiful coloration these photonic structures are far from perfect, and often contain a “certain amount” of structural disorder. While this is optimized in nature, man-made approaches to producing similarly brilliant colors are still in their infancy. Currently, the big stumbling block is the lack of a measure of the degree of order in the biological “blueprint”. We propose the use of ultra-small-angle X-ray scattering (USAXS) for a statistically meaningful quantification of the degree of order in 3D photonic structures found in weevil scales that contain various degrees of disorder, nicely demonstrating nature’s common approach towards producing distinct coloration. We therefore expect the USAXS experiments proposed here to shed light on the fundamental coloration mechanisms in weevils and similar biophotonic structures.

title: BAG Montpellier

description: The BAG of Montpellier gathers researchers from distinct institutes (CBS, IGF, IRIM and LPHI) affiliated to the INSERM, the CNRS and the university of Montpellier. The CBS is a node of the national infrastructure FRISBI. In this context, it is developping new methodologies for efficient ligand screening by X-ray diffraction. It is also involved in solving the structure of novel therapeutic targets to develop novel drug candidates. The IGF is involved in characterizing membrane proteins (mainly GPCRs) in order to better understand their functioning for therapeutic application. The IRIM and LPHI are focusing on several therapeutic targets related to infectious diseases in order to identify and develop novel inhibitors. CBS and IGF use SAXS to unravel the organization and behavior of various macromolecular systems in solution. Finally, we are now also turning to the use of cryo-electron microscopy to study some macromolecular assemblies.

title: Heidelberg BAG (HeidelBAG)

description: The HeidelBAG unifies structural efforts of the EMBL, the Heidelberg University Biochemistry Center (BZH), and the German Cancer Research Center (DKFZ). Central to all projects are large assemblies involved in chromosome organization and transcription control, in nuclear and cytoplasmic RNA regulation, in translational control as ribosome associated factors or further on in protein targeting, membrane protein insertion or post-translational modification. As new members, Mandy Jeske from BZH adds projects on early embryonic development in Drosophila and Erec Stebbins from DKFZ on immune evasion of the African trypanosome T. brucei. Nearly all projects make use of integrated structural biology techniques (MX, SAXS/SANS, NMR, cryo-EM) combined with complementary biophysical, biochemical and cell biological approaches, a strategy that warrantied the continuous success of the BAG. More and more pathological implications of the studied central cellular processes come into focus.

title: Wide-angle X-ray diffraction tensor tomography for 3D mapping of gallstones with chemical and orientational contrast

description: Pathological crystallization within the human body is a major cause of diseases like atherosclerotic plaques in arteries, urinary stones, gallstones and osteoarthritis. As part of our existing research objective to understand pathological crystallisation in the human body, we aim to understand the intricate structural details of gallstones primary composed of cholesterol. In particular, we want to investigate how the 3D orientation of cholesterol and calcium carbonate/phosphate crystallites relate to the internal structure of the gallstones. In the proposed experiment we aim to utilize state-of-the-art wide-angle X-ray diffraction tensor tomography (XRDTT) to map in 3D the local variations of mineral orientation in gallstones. We expect that the proposed experiments will provide valuable insights into the mechanisms of gallstone formation and help establish a correlation between organic cholesterol phase and inorganic components in terms of the local orientational variations.

title: Following the formation of ThO2 nanoparticles with HEXS and SAXS

description: Actinide nanoparticles are raising considerable concern in the field of safe nuclear waste disposal. It has been demonstrated that actinide nanoparticles are a mean of geochemical transport of radioactive material in natural aquatic systems. Currently, the chemistry and reactivity of actinide nanoparticles is very poorly known and the present proposal looks in the direction of filling this gap. ThO2 is used as model for AnO2 and is the reasonable system to start with. The objective of this measurement campaign will be to investigate the formation mechanism of ThO2 nanoparticles prepared by solution chemistry by thoroughly characterizing the structure of the products formed during the precipitation process. We will investigate the influence of thorium stock solution concentration, pH, post-synthesis thermal treatment and aging on ThO2 nanoparticles size and crystallinity. The results will shed light on the synthesis conditions that favor nanoparticle formations and growth.

title: Density of H2O-CO2-NaCl fluids at crustal conditions and controls on the formation of ore deposits

description: The aim of this proposal is to determine the density of model H2O-CO2 and H2O-CO2-NaCl fluids (10-20 wt% CO2, 10-20 wt% NaCl) at P-T conditions relevant for the formation of ore deposits in the Earth’s crust, up to 500 °C and 1.5 kbar. The measurements will be conducted in the FAME autoclave using the X-ray absorption technique. The new data will be implemented in accurate equations of state PVTx that will allow the development of quantitative models for the mobility, transport and precipitation of metals in the crust.

title: Nanoscale characterization of mineral self-organized membranes in anoxic conditions: implications for the origin of life and life detection

description: Self-organized, iron-silica(te) membranes might have served as redox catalysts in the early Earth hydrothermal systems proposed as niches for the emergence of metabolism. Moreover, they have similar morphologies and composition to biologic iron filaments found in silica-rich rocks, including those considered the oldest on Earth. Yet, available information on the mineralogy of these nanocomposite membranes comes from experiments-analyses performed in presence of oxygen. To investigate their formation and composition in anoxic conditions that were prevailing in early Earth, we will perform the their growth in capillaries inside a glovebox chamber and characterize them at the nanoscale using high-energy X-ray scattering experiments, combined with PDF analysis, while maintaining them in inert atmosphere. These results will advance our knowledge on early Earth mineralogy, the catalytic role of such membranes in prebiotic chemistry and the recognition of traces of life in the rock record.

title: Structure and reactivity of As under extreme conditions: high pressure and high temperature synthesis of H-rich extended As-H structures

description: This proposal is aimed at investigating the crystalline structure of arsenic above 50 GPa and at exploring the high pressure and high temperature chemical reactivity of As with H2 for synthesizing new extended As-H phases. Experimental results from a previous beamtime (CH-5791) limited to 48 GPa suggest indeed the existence of a new incommensurate structure in As analogous to that of Sb-II, which has been reported in the heavier pnictogen but not yet in As, and the formation of a reaction product containing As-H bonds, possibly related to extended As-H phases with high H-content and high superconducting Tc predicted by theoretical calculations, but never experimentally observed so far. The outcomes of this study are relevant to fundamental chemistry of pnictogens under extreme conditions and to the high-pressure synthesis of new advanced materials.

title: Antiferroelectric-ferroelectric phase transitions and polarization dynamics in lead-free NaNbO3-based antiferroelectrics

description: The defining feature of antiferroelectric materials is the unique phase transition from antiferroelectric to ferroelectric states induced by an external electric field, which is accompanied by a significant increase in polarization and strain. The aim of this experiment is to investigate the mechanisms of these transitions in newly emerging lead-free antiferroelectric materials. In particular, the focus is on the origin of reversibility. This goal will be achieved by studying the structural/microstructural behaviour of three representative groups of antiferroelectrics in situ under electric field application while simultaneously measuring the macroscopic response. We expect to find structural origins responsible for reversibility, which is a prerequisite for the use of these materials in applications.

description: This record gives access to all supplementary data that forms the background to the paper: Daly, A., Hocker, F. & Mires, C., 2022. Dating the timbers from the ‘Sparrow-Hawk’, a shipwreck from Cape Cod, USA. Journal of Archaeological Science: Reports https://doi.org/10.1016/j.jasrep.2022.103374 In 1626, a vessel making its way to Virginia was forced off course and damaged in a storm, which drove the ship onto the eastern shore of the Cape Cod peninsula, Massachusetts. Onboard were two English merchants and some servants and farmers, many of whom were Irish. In 1863, a storm exposed the weathered remains of a vessel at Old Ship Harbor. At the time, it was hailed as the same ship that had brought the Virginia-bound passengers to Plymouth in 1626. Recent wiggle-match C14 dating and dendrochronology suggests that this is indeed a ship from the early seventeenth century.
