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 clear majority of the macromolecules under study is their relationship 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, the study of plant viral proteins, or aim at characterising macromolecules with potential biotechnological applications including drug delivery.

title: Serial (SSX): Southampton, Bristol, Essex, Exeter, KCL, Leicester Block Allocation Group (BAG)

description: The BAG coordinates work in serial synchrotron crystallography, SSX. We propose to collect low dose ground states on enzymes, ligand complexes, and redox sensitive metallo-proteins, using the fixed target chip or foil sample delivery systems at ID29. For time resolved work, we propose laser activated work as well as mixing experiments using tape-drive delivery. Further, we are interested in developing our microfluidic setup together with the ID29 team for fast mixing applications in time resolved work, which will require modifying the sample environment. This bag is extending: we are joined by the University of Leicester with two PIs, the University of Bristol with one PI, and an additional PI from KCL.
This bag will need access to icOS and TricOS to probe for reaction intermediates, to BM07 online spectroscopy, to standard crystallography beamlines to refine crystallisation and substrate addition, and potentially request a humidifier at the beamline as well as anaerobic capability.

title: Incremental geochemistry of extant crocodylian teeth: the need to establish a time frame

description: In the framework of this project, incremental δ18O and 87Sr/86Sr values (linked with living environment) as well as δ44/42Ca and δ15N values (linked with diet) have already been measured on teeth belonging to three different taxa of extant crocodylians. As those measures were made incrementally along the growth axis, they correspond to a time frame, that is the one of the tooth mineralisation rate of the specimen. Daily increments of dentine that are separated by the lines of Von Ebner1, can be counted on thin sections under light microscope to estimate the time represented in the whole dentine of each specimen, and the precise time recorded by each sampling point. Once variations in isotopic compositions (and thus ecology) will have been related to a time frame, this method will be applicable on fossil specimens tease apart the influence of ecological and environmental parameters.

title: Formation mechanism and kinetics of lipid-based nano carriers of mRNA.

description: We propose to investigate the formation of lipid-based nanocarriers of mRNA to obtain a generic understanding of its underlying mechanism and ultimately provide a generic methodology to design an efficient nanocarrier for a given polynucleotide/application. This request for beamtime would provide us with time-resolved structural monitoring of the formation process by coupling the intense and narrow X-ray beam available at ID02 with an original microfluidic chip that allows the mixing of two different solvents within 0.2 ms. We will perform SAXS measurements at different positions of the chip that operates in a continuous flow, which will enable us to obtain robust time-resolved scattering data and thus resolve the complex structure of the nanocarriers. The parametric exploration enabled by microfluidics will yield the formation/structure relationship underlying the formation of these promising objects.

title: 3D Nano(micro) tomography of salt aggregates study for CCS applications

description: Carbon capture & storage has been identified as a critical technology for addressing rising atmospheric CO2 levels. Saline aquifers are a promising storage candidate in numerous regions globally for CCS, yet their efficacy can be compromised by CO2-induced salt precipitation Salt can precipitate in different crystal forms with different properties and effects. The morphology and porous structure of salt crystals will depend on several factors e.g. evaporation rate, solute accessibility, characteristics of the solid surface. The proposed experiment aims to understand how salt precipitates on a solid substrate in porous media and how it grows via nucleation/growth on the same material. Nano/microporous salt aggregates, crucial to this investigation, have already been synthesized under various conditions as part of the ongoing research of the proposal participants. We expect to obtain a high-resolution 3D tomogram revealing the porous structure at unprecedented spatial resolution.

title: Chromium speciation studies for studying chemical reactivity of strontium and barium chromate-based pigments

description: The photo-degradation of strontium and barium chromate yellow pigments (SrCrO4, BaCrO4) from the 19th century remains unstudied. However, chrome-based yellow pigments are known for their tendency to undergo darkening when exposed to UVA-visible light. This darkening has been associated to the reduction of the Cr6+ into Cr3+ species for chrome yellow (PbCrO4) and zinc chromate (4ZnCrO4·K2O·3H2O) pigments [1, 2], a chromium speciation study for studying the chemical reactivity of SrCrO4 and BaCrO4 has yet to be conducted. To that end, we propose to perform a multi-technique investigation of artificially aged paint samples through the coupling of micro X-ray fluorescence (μ-XRF), and micro-X-ray absorption near edge structure (µ-XANES). The study of the photochemical-reactivity and the nature of the alteration products of these light sensitive pigments in oil medium will be key to improve the long-term conservation and restoration strategies of historical paintings.

title: Operando XAS of dewetted Ni nanoparticles on SrTiO3 single crystals for photocatalytic water splitting: A model system to study Ni stability

description: Ni is a promising co-catalyst for photocatalytic water splitting but it suffers from activity decay. We will use time-resolved operando XAS to investigate the deactivation mechanism of a model system based on dewetted Ni nanoparticles on SrTiO 3 single crystals. Results will enable rational design of photocatalysts based, e.g., on faceted metal oxide particles where HER and OER co-catalysts are site-selectively decorated on electron- and hole-collecting facets, respectively.

title: Hard X-ray Bragg Helical Dishroism: twisting the beams for future electronics

description: A novel technique combining Bragg coherent diffractive imaging with orbital angular momentum (OAM) beams to study structural chirality in Tellurium nanocrystals is proposed. Structural chirality, crucial in science, lack nanoscale study tools. This is partly due to the Friedel’s problem of using symmetric beams (plane waves) to distinguish between handedness. We address this by integrating BCDI's capabilities with OAM's sensitivity to chirality, a breakthrough demonstrated in preliminary tests on Pt crystals. We aim to refine this technique through further Pt crystal experiments, then apply it to Te nanocrystals grown on chiral mica and amorphous SiO2/Si substrates to elucidate their chiral helical structures and domains. This research promises significant insights into chiral materials, with implications for emerging technologies in electronics and quantum computing. We hope to potentially revitalizing X-ray nanoprobe with techniques with OAM beams.

title: Probing the impact of linear deformation on local meso-scale nanofibrillar self-assembly of bagworm silk by X-ray nanodiffraction

description: Silk threads spun by bagworms (Psychidae) show superb mechanical properties, resulting from a highly ordered fibrillar organization. The SAXS/WAXD analyses using nanoscale X-ray beam for a single bagworm silk (performed at ESRF, ID-13 beamline during SC5011and 5259) resolved an anisotropic structural feature made of a radial gradient in diameters of mesoscale nanofibrillar assembly. However, influence of such radial heterogeneity of mesoscale nanofibrillar assembly on the mechanical properties of bagworm silk has not been known. In order to clarify the influence of radial structural heterogeneity on the mechanical properties, we will conduct a dynamic SAXS/WAXD measurements using nanoscale X-ray beam during the single fiber stretching in this proposal, and we aim clarifying how the radial heterogeneity of mesoscale structural order affect on the superb mechanical properties of bagworm silk.

title: Interaction between defects, grain boundaries and triple-junctions during grain growth

description: When annealing a polycrystal, the boundaries between the grains move. Understanding the processes involved in this “grain growth” is a cornerstone of materials science and is pivotal for applications from tensile strength in structural materials to resistivity in electronic materials. The classical picture of grain growth under the curvature driving force has been challenged by recent experimental and theoretical works. It is believed that defects, which are missing in the classical picture and have not been detected experimentally, play an important role in grain growth. With the EBS upgrade and recent development of Dark Field X-ray Microscopy (DFXM), movies of the 3D grain structures and the defect-induced strain field can be mapped faster and with higher resolution. This will pave the way for a comprehensive understanding of the role of strain and defects in grain boundary migration – including a direct test of the recently developed defect-mediated grain boundary migration theory.

title: Straight out of the asteroid belt to the Nuclear Resonance beamline at the ESRF.

description: The Hayabusa 2 (HY2) and OSIRIS-Rex (O-Rex) missions returned to Earth, for the first time in History, samples from carbonaceous primitive asteroids. We recently conducted experiments at the Mössbauer Beamline of the APS and demonstrated that we can identify minerals and unravel redox evolution on such asteroidal materials using Nuclear Forward Scattering. Based on these results, pivotal information on the formation conditions of iron-bearing phases have been proposed but cannot be confirmed without measurements performed using a highly focussed and bright Synchrotron Mössbauer Source at low temperature. This setup is only available on ID14 (ESRF). We propose to analyse HY2 and O-Rex samples (loaned by JAXA and NASA) together with meteoritical analogues, to unravel the formation conditions of clay and oxide minerals present in these unique asteroidal samples. This will allow us to put firm constaints on the mineral carriers of water and oxidized materials during planets formation.

title: Magnetic field alignment

description: Methods for suppressing plasma inhomogeneity in the multi-cusp single-driver negative ion source for neutral beam injector were investigated via a 2.5D MCC-PIC model in KARAT code, accompanied by a 2D hydrodynamic model of inductively coupled plasma. In the basic ion source configuration plasma density parameters near PG are: asymmetry A = 0.24, coefficient of variation CV = 0.74, average value of electron density ne = 2.3·1017 m−3. Magnetic field alignment results are A ≈ 0, CV = 0.64, ne = 1.8·1017 m−3. Change of ∇p drift flow direction results are A = 0.20, CV = 0.64, ne = 2.1·1017 m−3. Blocking plasma drift via thin barrier plates results are A = 0.16, CV = 0.74, ne = 2.3·1017 m−3. Methods for plasma inhomogeneity suppression are successfully evaluated and useful negative ion source configurations have been found.

title: Algivorous Cercozoa shape the community composition of cryptogamic covers, the dominant vegetation in Polar Regions

description: Soil algae are the most important primary producers where vascular plants are absent, as in the Arctic and Antarctica. They give rise to species-rich microbial food webs in biological soil crusts (biocrusts). The terrestrial snow- and ice-free areas are in permanent expansion as glaciers retreat, leaving behind extensive areas of uncovered rock and new soil. Biocrusts stabilize the soil surface and have an important role in soil development. However, the microbial food webs and the nutrient and energy flow to higher trophic levels remain largely unexplored. Here, we characterized the microbial predator-prey dynamics of polar soils by combining molecular and traditional culturing techniques. Using high-throughput sequencing of environmental samples, we assessed the biodiversity and function of soil protists, applying a trait-based approach for acquiring and describing functional traits, i.e., the feeding behavior of heterotrophic protists in relation to microalgae. The study encompasses the analysis of biocrust samples of three polar regions. In the Arctic, one region was sampled - Svalbard in the Arctic Ocean (78°N) in July 2021. In Antarctica, two regions were studied, i.e. King George Island (62°S) in the South Shetland archipelago of Maritime Antarctica and the Thala Hills oasis in Enderby Land, East Antarctica (67°S), between January and March 2022.
