title: Structural studies of tubulin from Antarctic Fish

description: Microtubules (MTs) are ubiquitous cytoskeletal filaments composed of tubulin αβ dimers that participate in essential cellular processes, including mitosis and meiosis, intracellular transport and cell motility. Although much has been learned regarding microtubule assembly and function in “medium” temperature eukaryotes, relatively little is known in psychrophilic ectotherms (“cold-loving” organisms) whose body temperatures are determined by the environment. Here, we want to study the functional properties of tubulins from Antarctic Fishes (body temperatures = -2 to +2°C) which have demonstrated their ability to form microtubules at low temperatures. We would like to determine the structural bases of microtubule assembly analyzing the dimer of tubulin of Antartic Fishes in the presence of a DARPin (Designed Ankyrin Repeat Protein) designed to block tubulin polymerization and in presence of different GTP analogs. Future aim would also be the analysis of polymerized MTs at 0°C.

title: Determining the redox and mechanism for incooperation of Cs into UO2 nanoparticles via HERFD XANES and EXAFS spectroscopy

description: In the present proposal, HERFD-XANES and EXAFS measurements are sort at BM20 to determine the chemical state and 
mechanism of incorporation of caesium in UO2 nanoparticles. Such nanoparticles are found after a high burn-up time of UO2 and referred to 
as high burnup structures (HBS) which is a part of spent nucleal fuel (SNF). Scanning electron microscopy (SEM) and Powder X-ray diffraction 
(PXRD) measurements suggests incorporation of caesium into the crystal lattice. However, the mechanism for incorporation, particularly the 
local chemical structure is unclear and will affect their stability in SNF disposal scenario, hence HERFD-XANES and EXAFS measurement are 
sought on the U M4-edge and Cs L3-edge to determine changes. This work has implications for the storage and safety of SNF particularly in 
the context of the “instance release fraction” in which caesium is a part of and to draw appropriate conclusions for the storage of SNF.

title: Porcine tooth CDJ fatigue damage high-energy phase contrast imaging

description: We study the propagation of cracks and crack-arrest mechanisms across the interface between tooth dentine and root cementum. We use freshly extracted porcine teeth as they have diet and eating habits that can be compared to young adult human teeth, which we cyclically load in the lab. We apply for an imaging experiment, using high energy (70 keV +) with phase contrast, to reveal cracks and inclusions in the still-hydrated samples, as we need to distinguish between drying cracks and cracks induced by fatigue. Results from this experiment will help us elucidate design principles of a naturally grown bilayer composite that is designed to function for decades of cyclic loading in the living animal.

title: Structure, interactions, and dynamic self-assembly of tubulin with different tau isoforms

description: Tubulin nucleation and microtubule (MT) assembly are frequent events in cells. The mechanisms directing these processes are poorly understood, owing to the size of tubulin and its highly dynamic character. The MT-associated tau proteins, including six isoforms, are major determinants of axon cytoskeleton stability and dynamics. Malfunctions of tubulin and tau are involved in various pathologies including cancer and neurodegenerative diseases. We propose to use time-resolved solution small-angle-X-ray scattering (TR-SAXS) methods, and our advanced analysis tools to follow the coassembly dynamics of different tubulin with different tau isoforms. Our aim is to determine the structures and intermolecular interactions dictating how tubulin dimers and different tau isoforms dynamically nucleate, assemble, and interact with one another to form tau-stabilized MT.

title: High pressure synthesis and characterization of metal hydrides and nitrides

description: Recent advancements in high pressure (HP) techniques, combined with the development of 4thgeneration sources, have opened up access to a new chemistry of elements. This is evidenced by the significant increase in the number of new compounds synthesized in the megabar range over the last decade. Of particular interest are the new nitride and hydride compounds synthesized at high temperatures (T) and in the range of 50-250 GPa using the laser-heated diamond anvil cell (DAC) [1-6]. This project aims to significantly lower the synthesis pressure and obtain samples of new nitrides, hydrides, and hydronitrides by exploiting the strong reactivity of NH3 as a source of N and H.

title: Operando Scanning X-Ray Diffraction Microscopy on Ferroelectric Perovskite Thin Films

description: We propose to investigate ferroelectric switching in lead-free monoclinic (K,Na)NbO3 strained thin films. In order to correlate the inversion of spontaneous polarization with changes in atomic structure and domain morphology, operando (scanning) X-ray nano-diffraction shall be performed during/after application of an electric field intended for polarization switching. We plan to use a focused X-ray beam of typically 100 x 100 nm2 size which allows to visualize the temporal evolution of polarization domains and corresponding domain walls with high spatial resolution. These experiments will help correlate switching of spontaneous polarization with changes in atomic structure and domain morphology.

title: All-solid-state lithium batteries based on Li1+xAlxTi2-x(PO4)3 (LATP, x = 0.3-0.5) solid-state electrolyte and LiFePO4 (LFP) cathode active

description: All-solid-state lithium batteries (ASSLBs) have gained significant attention as a next-generation energy storage solution due to
enhanced safety, non-flammability, and superior thermal stability while providing higher energy density than conventional liquid-electrolyte
batteries. In this project, ASSLBs based on Li1+xAlxTi2-x(PO4)3 (LATP, x = 0.3-0.5) solid-state electrolytes (SSE) will be fabricated in the form
of thin membranes. LiFePO4 (LFP), a low-cost cathode material with a long cycle life, will be co-sintered with LATP to form a composite
cathode and assemble it with the LATP SSE layer, offering a safer, more energy-dense all-ceramic alternative to prevailing designs. The
electrochemical phase change during cell cycling will be systematically investigated using synchrotron X-ray diffraction (SXRD).

title: Cryo X-ray nano-holotomography on a Hydrated Polymer Porous Membrane

description: Polymer porous membranes are widely used as filters in various industrial applications. Characterizing the pore structures in their operating condition, i.e., hydrated states, is essential because the structure is affected by the environment. X-ray imaging techniques can potentially be utilized for the wet imaging of pores. However, irradiation-induced deformation of samples hinders high-resolution imaging. To overcome this challenge, we propose X-ray nano-holotomography on hydrated membranes under cryogenic conditions. This experiment will enhance our understanding of the structure-performance relationships in membrane science.

title: Studying phase transitions in single crystals of sulfate minerals under HP and low T

description: The focal point of the current study is the crystal chemistry of the syngenite, gorgeyite and polyhalite minerals and their structural behaviour in conditions of both high pressure and low temperatures. The low temperature experiments are designed to yield the necessary data to complete and supplement a comprehensive study of the behaviour of these minerals over a wide range of temperatures and pressures. The proposed experimental plan centers on the study of single-crystal samples of these minerals, using a diamond anvil cells and helium as the pressure transmitting medium.

title: Effect of novel triple twin variant selection on fatigue crack-tip behaivour in Ti alloy

description: Metals normally deform by plastic deformation mediated by the movement of dislocations. Through additive manufacturing we have developed a novel Ti alloy comprising nano-scale martensite having a unique triple-twinned substructure. Uniquely, this deforms to large strain not by plasticity, but by detwinning as one or more twin variants grow at the expense of the others. So far only the tensile response has been studied but its fatigue response is potentially of great interest. This novel strain hardening mechanism is expected to activate near a fatigue crack tip in a unique way, redistributing stress during fatigue crack propagation, providing exceptional crack propagation resistance. In this proposal we aim to:
• map the crack tip-stress field by high resolution XRD over a fatigue cycle.
• track changes in variant selection (texture) during crack opening and closing,
• quantify the size and shape of the ‘plastic’ zone .
• extract the stress intensity factor directly fro

title: 3D mapping of dislocation grain-boundary interactions in SrTiO₃ with DFXM

description: Grain boundaries (GBs) in functional oxides strongly obstruct dislocation motion, affecting both mechanical and functional properties. In SrTiO₃, GBs hinder dislocations and often initiate cracks, limiting dislocation-mediated functionality. We propose using Dark-Field X-ray Microscopy (DFXM) at the ID03 beamline to perform a high-resolution 3D study of dislocation–GB interactions in SrTiO₃ bicrystals (both low‐ and high‐angle boundaries). By correlating 3D dislocation networks with local strain fields near GBs, we aim to reveal the mechanisms behind slip transmission, pile-up, or crack initiation. This insight will aid in engineering tougher oxide ceramics with tunable properties. Our method uses Brinell indentation to generate high dislocation densities near GBs while preventing crack formation, yielding unique 3D maps of dislocation arrangements and elastic strains.

title: Ferroelectricity and ferroelasticity inside GeTe thin films grown on stepped silicon substrates

description: Ferroelectric structures in thin films result from the combined effects of mechanical stress induced by the substrate and electrostatic/mechanic boundary conditions at ferroelectric domain walls. In that respect the control of ferroelectricity in thin films can be achieved by using strain engineering methods, i.e. selecting suitable substrates and applying thermomechanical stresses through thermal processes.
Here we aim to investigate the stress relaxation mechanisms and ferroelectric structures in GeTe thin films grown by MBE on miscut Si substrates. A 3D mapping of reciprocal space around GeTe ferroelectric Bragg peaks will be performed by GIXD to quantify the anisotropic stress relaxation state and ferroelectric domain structure. Their evolution as function of temperature and film thickness will be addressed. The role of atomic steps on stress relaxation processes and ferroelectricity will be deciphered by close comparison with GeTe thin films grown on a nominal Si substrate.

title: Effects of the volume compression on 5d electronic states investigated by X-ray absorption spectroscopy at ultrahigh pressures up to &gt;400 GP

description: To verify the pressure effects on the spin-orbital coupling and their universality in 5d transition metals, we measure XAS profiles of tantalum and platinum under high pressures up to 400 GPa or greater by using double stage-DACs. Mostly unoccupied 5d electrons of Ta and nearly occupied 5d states of Pt are choosed to examine the pressure effect.

title: XAS/XES probing chemical evolution in Solid-state Cl-ion batteries with conversion electrodes

description: This project aims to study the redox mechanism of composite electrodes in solid-state chloride-ion batteries (CIBs) via tender x-ray absorption/emission spectroscopy. By using solid cells with composite electrodes as samples, the emission lines and the absorption spectra can be measured on Cl K-edge and the respective metal edges, allowing us to probe the redox-active species and their evolution at different charge states and cycles. In combination with other complementary techniques, we want to understand the fundamental mechanism of the conversion reactions for these metal chloride electrodes, and to identify the factors hindering the reversibility and stability in prolonged cycles. The findings will provide a valuable guidance on the selection of metal chloride cathodes, and help the rational design and optimization of CIBs for enhanced energy/power density and cycle life.

title: Uniaxial Strain effect on the electronic structure and magnetic interactions of thin-layer nickelate superconductor

description: Infinite-layer (IL) nickelates offer promising insights into unconventional superconductivity. While epitaxial strain from substrates modifies electronic and magnetic properties, influencing superconductivity, the decoupling of externally applied from epitaxial strain remains underexplored. We aim to investigate the spectroscopic response of IL PrNiO2/STO using a piezoelectric-based uniaxial strain cell for precise strain application, offering an accurate and tunable approach. Building on evidence that uniaxial strain enhances magnetic exchange interactions, we will employ Resonant Inelastic X-ray Scattering (RIXS) to investigate how strain alters electronic and magnetic properties and their relationship to the superconducting properties.

title: Toward Innovative Tissue-Adaptive Polymer Materials for Soft Wearable Electronics

description: In the proposed experiment, we intend to explore a novel family of soft electroconductive materials based on biomimetic bottlebrush polymer networks. By integrating linear chains of poly(3-hexylthiophene) -P3HT in poly(dimethyl siloxane)- PDMS bottlebrushes, one can develop conductive elastomers that exhibit mechanical properties resembling those of biological tissues. The aim of this study is to explore the structure of the percolated P3HT scaffold within the bottlebrush matrix and its behavior under mechanical deformation.

title: Severe Fever with Thrombocytopenia Syndrome Virus Infection Induces Thymic Atrophy in IFNAR<sup>-/-</sup> Mice

description: Severe fever with thrombocytopenia syndrome virus (SFTSV) causes severe disease in humans, yet the pathogenesis remains poorly understood. A hallmark of fatal SFTS cases is the marked depletion of T cells. Previous studies on T cell depletion have predominantly focused on alterations in blood and peripheral lymphoid organs, while the thymus, a critical site for T cell development, has remained largely overlooked. In this study, we employed a lethal murine infection model to investigate the impact of SFTSV on thymic function. Our results revealed that SFTSV infected the thymus and induced severe cortical atrophy in type I interferon receptor-deficient (IFNAR<sup>-/-</sup>) mice, characterized by a dramatic depletion of CD4<sup>+</sup>CD8<sup>+</sup> double-positive (DP) thymocytes. Transcriptomic analysis indicated that thymic damage is likely attributable to impaired thymocyte proliferation and increased apoptosis, which may be a consequence of SFTSV-induced alterations in the thymic microenvironment. We found SFTSV-infected macrophages and dendritic cells in the thymus, which accumulated in the cortex and exhibited elevated secretion of IFN-γ, a cytokine commonly associated with acute thymic atrophy. These results demonstrate thymic atrophy caused by SFTSV infection and suggest potential therapeutic strategies for restoring thymic function and promoting T cell reconstitution.
