title: Formation mechanisms of high-entroopy spinels studied by coupled X-ray diffraction, total scattering and absorption spectroscopy

description: Using combined X-ray diffraction (XRD), total scattering (TS), and X-ray absorption spectroscopy (XANES) experiments, we want to study the formation of high entropy oxides (HEO) in a sol-gel synthesis. HEOs are a new type of material containing five or more metal cations in a single-phase crystal structure. We have synthesized a series of HEOs in a spinel structure based on 1st-row transition metals (Cr, Mn, Fe, Co, Ni, Cu), which have immense potential as e.g., catalysts for oxygen evolution reaction (OER). We aim to obtain a mechanistic understanding of the oxide formation pathways in these multi-metallic systems. The combined in situ XRD, TS, and XANES studies will allow us to simultaneously follow changes in the average and local structures as well as oxidation states during the transformation of the amorphous precursors into crystalline products. Such studies have previously shown to give unique insight into the materials formation pathways of novel high entropy materials.

title: Dynamics of vesicles in dense pools studied by XPCS-microrheology (cont’d): extension to synaptic vesicles and active systems

description: We propose to study the dynamics of synaptic vesicles and of artificial lipid vesicles in dense vesicle pools by X-ray photon correlation spectroscopy (XPCS), extending our previous work on artificial lipid vesicles. Pools are aggregates of vesicles which are clustered together by proteins causing an attractive interaction. We are interested in the short range (hindered) diffusion of vesicles which are at least partially arrested in the pool. The dynamics takes place on much slower timescales than free diffusion, and can also be distinguished from free diffusion via the q-dependence.

title: Unraveling the relation of the Mechanics and nano-structure of Sea Urchin Spines for Bio-Inspired Materials

description: Sea urchin spines possess intricate 3D structures, combining strength and flexibility. These remarkable properties arise from a unique composition, including varying magnesium distribution and amorphous material. By subjecting the spines to mild heat treatments, previous research showed changes in flexibility, suggesting the role of compositional variations. Our proposed study employs nanotomography and in-situ annealing to track temperature-induced alterations in spine morphology and microstructure. Detecting density changes may reveal the crystallization of amorphous particles and shed light on non-uniform magnesium distribution. This investigation deepens our understanding of sea urchin spine mechanics, offering insights for bio-inspired materials.

title: Determination of crystallographic structure of a mitochondrial serine protease HtrA2 under high hydrostatic pressure to characterize its con

description: The crystallographic structure of HtrA2, a mitochondrial serine protease involved in apoptosis, together with molecular simulation studies and viscosities analysis have revealed that the flexibility of two regulatory loops lining the active site is related to functional efficiency and to the high thermostability of the enzyme. The crystallographic structures of different mutants, either in a closed or open conformation, support the hypothesis that the flexibility of the loops surrounding the active site is necessary for catalytic efficiency. High hydrostatic pressure crystallography is an ideal technique to trap high energy transient conformers involved in enzymatic activity and/or interaction with partners. The analysis of the crystallographic structures of HtrA2 WT and various more rigid mutants under high hydrostatic pressure will allow us to identify precisely the determinants of HtrA2 plasticity related to its functional efficiency and high thermostability.

title: Bridging the gap between cellular and whole body imaging using Hierarchical Phase-Contrast Tomography: HiP-CT

description: Humans and other large organisms are three-dimensional multiscale biological systems where large scale function and structure are dependent on the macrostructure’s interconnectivity down to the cellular and subcellular level. Using the exceptional coherence provided by the ESRF-EBS, we have demonstrated that propagation-based phase-contrast can effectively decouple resolution from specimen size in soft tissue, obtaining 1.4 micron voxel resolution in 150 mm diameter human organs. Through this Long Term Proposal (LTP) we will develop the techniques required to image whole human and animal bodies ex vivo at 25 micron resolution, zooming to sub-micron voxels (0.7micron) locally, resolving sub-cellular structures through hard- and soft-tissue. Resolving how the micro (sub-cellular) interacts with the macro (whole organism) across length scales will provide all new insights into biological and biomedical function. This is true for both healthy and pathological system level behaviour.

title: Temperature dependent plasticity in BCC refractory multi-principal element alloy micropillars

well as by in situ Laue microdiffraction during microcompression at ambient conditions.

title: Milliseconds to seconds timescale, filling the gap in the photo-reaction of carH with time-resolved X-ray scattering in solution.

description: The protein carH associates with the B12 vitamin to form a light-sensitive gene repressor in bacteria. The gene repressive state in the dark binds to the DNA as a tetramer. The light triggers the dissociation of the adenosyl group from the cobalamin, the coordination of the cobalt to the H132 of carH and the dissociation of the tetramer. We recently obtained time-resolved wide-angle X-ray scattering (TR-WAXS) results regarding the tetramer to monomer transition of a truncated form of carH (TtCBD) but we still lack information about the oligomerization change for the full-length carH and for two other variants, the TtH132A mutant and the HmCBD homologue. To this end, TR-WAXS will be used on ID09. Preliminary results on TtCBD show the presence of two structural intermediates relaxing within 3 ms and 300 ms before the tetramer dissociation occurs. We aim at collecting data on the other carH variants for long time delays ranging from 100 ms to 5 s as recently achieved on ID09 for TtCBD.

title: Synthesis of chromium-doped YAG nanocrystals via Pechini synthesis and coprecipitation

description: Chromium IV-doped Yttrium Aluminum Garnet (YAG) materials are widely used as saturable absorbers (SA) in YAG:Nd lasers. However, the low doping rate
(about 1%at) reported in literature leads to poor SA properties whereas the complex doping mechanism of the matrix leads to a cohabitation between various
ions: Cr3+, octahedral Cr4+ and tetrahedral Cr4+. As only the latter is responsible for the SA properties, its concentration must be manageable to achieve better
properties. We successfully synthesized YAG:Cr powders with a Cr doping rate of up to 30%at via Pechini synthesis and coprecipitation. UV-Vis spectroscopy
suggests that the synthesis route has an influence on the Cr oxidation state and on its crystallographic environment. The goal of this proposal is 1/to identify these
features depending on the synthesis route and thermal treatment to unravel the synthesis and doping mechanisms and 2/to define the best conditions leading to
the most efficient SA.

title: Examining the Local Order and Stability of Copper-Exchanged Zeolite Omega For the Methane-to-Methanol Conversion via In-Situ PDF & XRD

description: The methane-to-methanol conversion is seen as one of the "holy grail" reactions of catalysis. One extensively examined pathway is the chemical looping
approach using copper-exchanged zeolites. Copper-exchanged zeolite omega has outperformed all other examined copper-zeolites in multiple metrics such as productivity. Further increases may be envisaged by increasing the copper-loading or modifiyng the zeolite framework to exhibit a hierarchical pore structure. However, besides potentially destabilizing the framework, a change in the nature of the reaction as well as the active site is possible. 

This proposal aims to investigate the stability of the long-range structure of the system and pinpoint the changes in the local order of copper-active sites under different conditions. This will be done by using time-resolved high energy powder XRD and PDF, coupled with mass spectrometry.

title: Measuring the microscale origins of functional fatigue in materials with martensitic transformations with varying mechanical hysteresis

description: The aim of this experiment is to measure the interfacial stress fields that lead to functional fatigue in materials that undergo martensitic phase transformations (MPTs) such as shape memory alloys (SMAs). MPT is a diffusionless, often reversible phase transformation between a high-symmetry and a low-symmetry phase. It is the enabling mechanism behind the novel properties of SMAs and TRIP steels, but functional fatigue continues to be a major barrier. Functional fatigue is caused by stress fields that form at the phase interface and lead to dislocation generation. We plan to use dark-field X-ray microscopy (DFXM) to measure these interfacial stress fields during stress-induced MPT, using a mechanical load frame. A strong factor in the fatigue properties is the kinematic compatibility. NiTiPd SMAs have tunable kinematic compatibility and several compositions will be mechanically cycled to observe how dislocations develop and influence the functional fatigue behavior.

title: XAS investigations of field induced valence transitions in Eu(Rh1-xIrx)2Si2 series

description: Using time-resolved x-ray absorption spectroscopy (XAS) measurements, we propose to study the field and temperature induced valence fluctuation in a particular model system, Eu(Rh1-xIrx)2Si2 series. Main aim of the proposal is to identify possible differences in the effects of field and temperature on the average Eu valence within and beyond the critical end point of an existing first order valence transition . A systematic comparison of the field and temperature dependencies of the valence in the vicinity of the critical end point has long been desired, but never been performed using direct probes such as XAS. Expected data will be useful for better understanding the nature of field induced valence fluctuation and relevant field induced phenomena.

title: The d band structure of Ru clusters in NH3 synthesis

description: NH3 is one of the most important chemical products but only made at 400-500 C and 150-300 bar conditions due to the stable N2 molecule. Here we have developed a Ru-CeO2 catalyst with high activity under 1-10 bar. Kinetic study reveals a H-assisted N2 dissociation mechanism, with a volcano-type activity dependence on the N2 activation barrier and the H2 adsorption strength. To validate such mechanism and volcano trends, we need to understand: 1) How the Ru d band centre determines the N2 activation behaviours; 2) Does the d band centre change along with reaction conditions; 3) How does N=NH* formed on Ru surface. Here we apply for an in situ Ru L3 edge vtc- RIXS study to follow the dynamics of Ru d band and identify Ru-N=NH under NH3 synthesis conditions. This study utilizes the uniqueness of the in situ tender RIXS capability at ID26. It is also a perfect synergy between in situ RIXS study and experimental kinetic models, which is the first of its kind for NH3 chemistry.
