title: Structure of biomolecular condensates

description: Biomolecular condensates are important organizers of cellular biochemistry. Understanding their structure and function can, for example, shed light on several neurodegenerative diseases. Although biomolecular condensates play such an important role, we barely understand their internal structure. So far, it is known that structures below the optical resolution limit are proposed to exist. These scales are accessible with X-rays, which are well suited to quantifying the organization of molecules through the structure factor. Here, we propose experiments at the BioSAXS BM29 beamline at the ESRF to further unravel the structure of biomolecular condensates. We hope that these experiments not only shed light on our own system, but also again demonstrate the power of X-rays to a growing community of condensate scientists.

title: Investigating the metamagnetic phase transition in FeRh.

description: FeRh undergoes an AFM-FM phase transition at about room temperature. Associated with a structural (lattice expansion) and resistivity changes amongst other key characteristic changes, this metamagnetic transition positions the material as a potential candidate for applications in memrsistive device development and ultimately neuromorphic computing. The objective of the experiment is to investigate with a nanometric resolution the effects of the transition on the structure of the sample and ultimately correlation with the magnetic properties of the material.

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: Carbon capture in redox trapping systems: sulfide - carbon dioxide interactions at hydrothermal pressures and temperatures

description: Global carbon dioxide emissions are continuously increasing leading to a global increment in temperature with potential massive consequences for our planet and society. This pilot project aims to investigate the reactions occurring at hydrothermal conditions in the CO2-sulfides systems in order to discover innovative ways to mitigate the release of anthropogenic CO2 into the atmosphere. The project will address this topic through a series of experiments that will provide results on the stability and reaction pathways of supercritical and solid CO2 with pyrite (FeS2). The results will pave the way for future research in multiple, deeply interconnected fields since the project will not only help to further clarify the potential applications of CO2-sulfide systems for the capture of CO2 but will also provide new information to understand the behaviour of the CO2-sulfide systems at high pressures and temperatures.

We will focus on the shape and crystallographic nature of the alumina in the reactive process.

title: Probing the Local Chemical Environment for Redox Exsolution of Nano- and Endoparticle Electrocatalysts

description: Metal nanoparticle catalysts dispersed on the surface of a perovskite oxide support show great promise in solid-state electrochemical devices for energy
conversion and electrification of chemical processes involving hydrogen. Breakthrough (electro)catalyst performance and durability have been achieved by direct
growth of nanoparticles from the oxide support by exsolution, and thus exhibit strong anchoring that inhibits agglomeration. Our hypothesis for explaining the
observed results involves transition metals (TM) on interstitial positions in the perovskite structure, where small TM can dissolve into a square-planar configuration
adjacent to A-site vacancies. The potential role of such interstitial solubility of TMs has so far not been addressed in understanding exsolution processes. The
combined in situ XAS and total scattering data of synchrotron experiments will allow for a detailed model of short-range ordering and local distortions in certain
cation environments.

title: SrH22 as an analog to metal hydrogen in the 200 GPa range.

description: The bandgap closure of solid hydrogen into a molecular metal has recently been experimentally observed, but its detailed electronic and structural characterizations remain at the very edge of current high pressure physics capabilities. In 1983, N. Ashcroft suggested the possibility to use impurities to lower the hydrogen metallization transition pressure. The recent discovery of SrH22, the metal hydride with the highest hydrogen content discovered so far, offers to put in practice that prediction. The insulator to metal transition by bandgap closure in Sr-doped molecular hydrogen compound is expected to occur around 220 GPa.
This proposal aims at reproducing the synthesis of the SrH22 compound, to obtain it in pure form to be able to refine its structure, and to determine its pressure stability range and the structural changes upon entering the metal state. The structural study will be complemented by IR absorption measurements in our laboratory to measure the bandgap closure.

title: "Nano-tomography and nano-XRF analyses to investigate sociality recorded from lensoidal to spheroidal microfossils during the Archaean."

description: Conditions on the early Earth were hostile with intense UV radiation, but cells still managed to adapt and thrive. The evolution of new metabolic pathways is the obvious route by which cells coped with environmental pressures, however, the social lives of cells were just as important. Cooperation and sociality are the well- known mechanisms for dealing with environmental stress and the evolution of complexity, but how this played out in the earliest prokaryote groups is unknown. A palaeontological angle to this issue is almost entirely unexplored and represents a huge gap in knowledge. We wish to address this gap, by examining the earliest fossilized evidence of sociality in Archaean cellular microfossils. This study will document for the first time the “sociobiological aspects” of the unusually large prokaryotes during the Archaean and provide clues related to their subsequent disappearance in the later history of the geological time till date.

title: Molecular bases of regulation of cardiac muscle contractility

description: Regulation of heart contractility is operated by both thin, actin containing filaments, and thick, myosin containing filaments. Ca2+-induced structural changes
in the regulatory proteins of the thin filament release the actin sites for interaction with myosin motors. Thick filament mechanosensing adapts to the load the
number of motors recruited from the OFF state in which they lie tilted back on their tails unable to interact with actin. In the heartbeat both thin and thick filament
activations are under the control of modulatory mechanisms by accessory proteins. Mutations in these proteins cause dysregulation and cardiomyopathy. We use
sarcomere-level mechanics and X-ray diffraction on intact and demembranated myocytes of the ventricle of wild type, mutant and transgenic animal models to
investigate the mechanisms that control thick filament regulation/dysregulation and test small molecules candidate as therapeutic tools.

title: Metal uptake and distribution by Toxoplasma gondii

description: Transition metals, such as iron and zinc, play essential roles during infection. Our work focuses on the eukaryotic parasite Toxoplasma gondii, a ubiquitous
pathogen of humans and animals, which needs to subvert transition metals from its host cells to power the parasite's replication. We have identified the proposed iron
transporter, but recent work suggests it also has a role in zinc uptake. In this proposal, we seek to confirm this, and determine for the first time how T. gondii infection alters the quantity and localization of both iron and zinc in human cells. Recently, we have also created two parasite lines deficient in putative copper transporters and we plan to compare copper localisation in these cell lines to identify the first potential Toxoplasma copper transporters. This work continues our recent, successful visit in May, expanding on these results to fully determine the role of iron at this host-parasite interface.

title: Determination of O and Si exsolution during the crystallization of iron at planetary cores conditions determined using X-ray Absorption Spec

description: Planetary cores are constituted of iron alloyed with lighter elements (S, C, O, Si or H). Understanding the phase diagrams as well as the physical properties of these alloys under extreme conditions is crucial to model the thermal evolution and the dynamics of core crystallization, at the origin of the magnetic field. In the present proposal, we plan to use LCF to obtain quantitative composition from XAS spectra acquired at high pressure in the temperature quenched samples, employing the laser-heating set-up available on ID24 DCM. This will enable us to determine binary or ternary phase diagrams under extreme conditions.

title: Availabity of HgS nanoparticles for Hg methylation by sulfate reducing bacteria

description: Methyl mercury is highly toxic and is mainly produced by sulfate reducing bacteria (SRB) in anoxic aquatic ecosystems. Understanding this Hg biomethylation process is important. In this study, we examine the role of bHgS nanoparticles in Hg methylation by the model SRB strain Pseudodesulfovibrio hydrargyri (BerOc1). Our objective is to identify and quantify the various Hg species in the cells and different fractions. For that, we will use Hg L3-edge High-Energy Resolution Fluorescence Detected -X-ray Absorption Near Edge Structure spectroscopy (HERFD-XANES) from FAME-UHD beamline that proved powerful to determine Hg species.

title: Study of the influence of stretching on the macromolecular dynamics of polylactide by means of Xray Photon Correlation Spectroscopy (XPCS) m

description: The goal of this proposal is twofold. On the one hand it aims at improving the previously developed setup allowing simultaneous WAXS/XPCS measurements besides by adding a SAXS detector in order to track the structural evolution at the nanometer scale. On the other hand, the goal is to consolidate the previously carried out measurements and to go deeper in order to answer the remaining questions. In this way, one aim is to determine if the slowdown of the relaxation times observed with the increase of crystallinity arises from a constraining effect due to the formation of crystalline lamellae and/or originates from an increase of nanoparticles concentration (i.e. tracers) into the amorphous domains involved by a segregation effect. Also, more precise and exhaustive measurements will be carried out on stretched samples in order to confirm the fact the dynamics heterogeneities and to determine the critical orientation degree above which they are observed.

title: Origin of Athermal Photo-Induced Effects in Chalcogenide Glasses:

description: With the proposed experiment, we aim to analyze the specific structural changes occurring at a local level when chalcogenide glasses are exposed to photon beams. We intend to quantify and compare the impact of photons with energies around the bandgap (~eV) of the glass and those within the hard X-ray spectrum. The EXAFS spectra will enable us to examine the athermal local atomic rearrangements induced by photons of varying energies and polarizations. Our objective is to enhance our understanding of the microscopic mechanisms underlying the photo-induced phenomena observed in this family of glasses.

title: Determining structural and kinetic pathways for non-canonical DNA structures with time-resolved X-ray solution scattering

description: We propose an ESRF beamtime to study pH-driven DNA structural transitions using time-resolved X-ray solution scattering (TRXSS). Our focus is on the structural pathways from Watson-Crick (WC) double-stranded DNA (dsDNA) to non-canonical i-motif and G-quadruplex (G-quad) structures. These non-canonical DNA structures play vital roles in biology such as regulation of gene expression and telomere maintenance. While their thermodynamics are understood, their kinetics, especially in competition with WC dsDNA, are less explored. We plan to use a visible-light-sensitive photoacid to induce pH changes with a nanosecond laser and monitor dsDNA dissociation and i-motif and G-quad formation kinetics with TRXSS. Complementary Molecular Dynamics simulations will use the TRXSS results to examine the structural trajectory along the kinetic pathways. Our study aims to unveil potential intermediates involved in dsDNA dissociation and provide insights into nucleic acid structural transitions.

title: Structural characterization of new 2D materials: single layer NiS2 and Janus NiOS

description: The objective of this proposal is to explore a novel class of 2D materials based on iron (Fe) and nickel (Ni) that do not naturally occur as freestanding atomically
thin layers or as bulk mineral compounds. In our recent experiments, we utilized in situ Grazing Incidence Surface X-ray Diffraction (GI-SXRD), scanning tunneling
microscopy (STM), Auger electron spectroscopy (AES), and electron diffraction techniques to characterize physical vapor deposition (PVD) grown 2D NiS2 and NiOS supported on Au(111). Our investigations also revealed that 2D FeS2 forms a Janus-type asymmetric material with FeOS composition, offering exciting
prospects for ferroelectric or spin-polarized properties. Here, we aim to show that NiS2 also forms 2D Janus oxy-sulfides with the classic X-M-X TMDC structure,
stabilized by the interaction with a suitable substrate, Au(111). Ultimately, we will benchmark a general experimental technique of synthesizing alloy Janus 2D
TMDCs of any d-block transition metal.
