title: Time resolved protein structures with 1000 Hz X-ray pulses in the 10-100us time range

description: .A group which has pioneered work at Free Electron Lasers for time resolved structural work on proteins we are interested to understand biologic processes from the structural point of view like Enzymology and Light driven reactions like photosynthesis or light triggered reactions of eg cytochrome c oxidase. From health science we try understanding the binding of drugs to fight cancer and the mechanism of Nendo U one of the proteins which gets expressed during Covid infection, this virus specific protein cuts off the poly U end from RNA. A targeted inhibition or suppression of the Nendo U would support the natural immune answer to fight Covid and similar viruses. 
The bromodomains are involved in the regulation of various human cancers. We have proteins of several bromodomains to study potential drug ligands with nanomolar KD in their time resolved binding.

title: Time lapse in situ X-ray imaging of fatigue cracking events in IN718 alloys at elevated temperatures

description: AM IN718 superalloy show great potential in aero-engine turbines, which experiences cyclic loading under long-term heat system. However, inherent defects occurring during the AM process can serve as crack initiation sites, leading to diminished high-temperature fatigue properties. Very limited knowledge has been revealed regarding the transition of internal defects to cracks and their role in failure within AM IN718, crucial for accurate strength and life prediction, particularly under extreme high-temperature conditions. In situ SR-µCT provides valuable 3D characterization of damage and crack formation in critical structural materials. Our specialized in situ environment rig allows visual exploration of this sequence at elevated temperatures. This information enables precise monitoring of fatigue crack initiation and propagation, facilitating accurate failure sequence prediction, and ultimately extending the safe operational lifespan of AM IN718 superalloys at elevated temperatures.

title: Noble gas storage capacity of bridgmanite and the outgassing history of the Earth

description: The outgassing history of the Early Earth remains a key topic in geoscience because the presence of volatile species in its interior,
 such as H2O, CO2, has a strong influence on its dynamics and evolution. We know that most of volatiles have been outgassed from the uppermost Earth's mantle while a significant fraction of volatiles have never been outgassed from the deeper Earth. The location of these deep volatiles remains highly debated. The solid Earth's lower mantle is one potential candidate, but the few literature data on noble gases solubilities in its main constituent, bridgmanite, concern mainly Ar and are controversial. Data on heavy noble gases at relevant conditions are required to validate or reject the scenario. Here, we propose a new approach to constrain the amount of Kr and Xe retained in bridgmanite at relevant conditions (25-130 GPa, 2000-4000 K) based on quantitative in-situ µXRF and single crystal XRD measurements in the LHDAC at high dilution levels.

title: Coherent, bright and focused light to resolve neural circuits

description: One of the grand quests in neuroscience is to build complete maps of the brain, charting all of its cells and the connections between them. Such wiring diagrams, called connectomes, promise to shed light on how networks of neurons can give rise to thoughts, memories, and actions, and to help reveal the underlying causes of neurological diseases. However, due to the scale of mammalian brains new technologies are needed to comprehensively map them.
In our previous LTP (LS2892, 2021-2023), we established X-ray coherent microscopy as a new technique for mapping of large tissue samples. We propose extending our LTP to use the techniques we recently developed to map several brain regions with unprecedented detail, including the neocortex, cerebellum, and hypothalamus. These datasets will reveal fundamental organizational principles of brain networks, and further establish X-ray microscopy as a critical technique for global efforts to completely map mammalian brains.

title: Exploration of regeneration process in Pt-Ga catalysts supported on alumina for propane dehydrogenation

description: Propane dehydrogenation (PDH) is one of the main industrial processes to produce propene. Notably, catalysts for PDH reaction require constant regeneration because of fast catalyst deactivation due to coking and sintering. In that context, we have found that Pt-Ga bimetallic systems supported on Si-doped alumina displays enhanced activity and stability for PDH compared to monometallic Pt systems supported on alumina. In order to understand the difference between "good” and “bad” catalysts depending on the surface dopants and additives, we plan to carry out in-situ and operando XAS studies during PDH and subsequent regeneration tests using a series of Pt-Ga systems with tailored surface sites as model catalysts prepared via surface organometallic chemistry (SOMC). Repeating the cycles of PDH and regeneration will allow us to identify the roles of dopants and additives on catalyst productivity and stability by amplifying the spectra differences.

title: Correlating Critical Dynamics to an Onset of a “Hidden” Metastable Phase in 1T-TaS2

description: 1T-TaS2 is a van der Waals transition metal dichalcogenide material with unique ‘Star of David’ charge density wave (CDW) states at thermal equilibrium. Numerous studies have characterized the various CDW phases in 1T-TaS2 through observables such as resistivity, optical reflectivity, and scanning tunnelling microscopy, but experiments to study the recently discovered ‘hidden’ metastable CDW state have been less revealing. In particular, the temperature-dependent switching probability and the lifetime of the hidden phase lacks a fundamental explanation. Therefore, we propose to use x-ray photon correlation spectroscopy to directly measure equilibrium dynamics of the commensurate CDW phase to investigate the electronic environment favorable in opening the nonequilibrium pathway to the hidden phase. We aim to find the critical temperature and the corresponding dynamic environment within the commesurate phase that allows for the onset of the hidden phase.

title: Testing the feasibility of in situ electrochemical BCDI in aqueous solutions using Pd nanoparticles in the presence of glycerol as a reactan

description: We aim to evaluate the feasibility of using BCDI in situ to track changes in Pd nanoparticles morphology and strain during the electro-oxidation of glycerol. We aim to study Pd NPs as we change the external applied potential causing the adsorption/desorption of hydrogen, hydroxyl and the concomitant glycerol oxidation. However, before doing it, we need to tackle problems related to radiation damage, which are revealed by the formation of Pd hydrides at electrochemical potentials where the phenomena should not occur in HClO4 solutions. Pd hydride formation can be detected via X-ray diffraction. We can track the Pd hydride formation using different concentrations of glycerol. By doing that, we will check if the glycerol’s ability as a radical trapping agent is able to mitigate the radiation damage. Glycerol is a special molecule in our case because it can act not only as a trapping agent, but also as the biomass being electrocatalytically oxidized in our system.

title: Capturing Structural Evolution and Reaction Intermediates in Co3O4 During the Electrochemical OER with Time-Resolved XAS

description: Among many Earth-abundant catalysts, Co3O4 spinels have shown great OER activity. However, the precise mechanism through which water is oxidized, and crucially, its connection to the evolution of the active site, has remained unclear. Recent results from time-resolved ATR-FTIR photolysis experiments, have suggested the presence of two mechanistic cycles that achieve O-O bond formation: a fast one occurring on electronically coupled Co(IV)=O sites, and a slow one where the Co(IV) center is isolated. Nevertheless, no direct observation of the putative Co(IV), or the Co(II/III)-OOH species has been made under operando conditions to date. Time-resolved Co K-edge XAS with the fast monochromator of ID24 will provide crucial oxidation and spin state information of the cobalt ions (XANES) as well as coordination environment information (EXAFS) in the few seconds range after an electrochemical potential bias is applied to a well-defined Co3O4 precatalyst.

title: Enabling deep understanding of Power-to-Ammonia catalysts for renewable fuel production with the help of transient operando photon-in/photon

description: This LTP is motivated by systematic studies on ammonia synthesis catalysts under the realistic conditions of the Haber-Bosch process, as employed for the production of sustainable renewable ammonia at offshore wind power plants. Over the course of 6 beamtime scheduling periods, electronic and geometric structure of active metals (Fe, Ru) as well as of electronic (K, Cs, Ca, Ba) and structural (Al, Si) promoters will be thoroughly studied at the ID26 beamline under stationary and transient conditions. In the course of the LTP a pixel detector will be installed in the TEXS which, together with sets of high quality Johansson crystals, which will enable X-ray Fluorescence Intensity Ratio Detection (XFIRD). Furthermore, a high pressure operando catalysis cell will be developed. The planned investments will enable spatially- and time-resolved operando tender X-ray HERFD-XANES and XES spectroscopy on working catalysts for chemical energy storage and related processes.

title: Elucidating structures, mechanisms, and kinetics using time resolved XAS for the continuous catalytic partial oxidation of methane to protec

description: We aim to identify the relevant species correlated to high methane-to-methyl-ester conversion activity in Mn/TiO2 catalysts and monitor the behavior and changes in Mn speciation/structure of these materials during reaction using time-resolved XAS. In particular, the influence of the protectant co-feed (used to prevent product overoxidation) on the speciation and structure of active Mn species will be measured in order to understand how this protectant may also modify the catalyst to produce enhanced methane conversion activity than what is achieved in the absence of the protectant co-feed. Using a highly improved reaction concept developed in the group combined with the advanced Quick XAS capabilities, we aim to complete the first in situ spectroscopy experiments for methane-to-ester chemistry, providing previously unattainable insights into one of the most selective methane partial oxidation pathways.

title: Understanding the role of Cu into the reactivity and stabilization of the prototype High Entropy Oxide Mg0.2Co0.2Ni0.2Cu0.2Zn0.2O

description: We propose to study reactivity and stabilization of the high entropy oxide Mg0.2Co0.2Ni0.2Cu0.2Zn0.2O, by applying high instrumental and spatial resolution XRD to diffusion couples (DCs). Since Cu is deemed to be the destabilizing element in this system, we focus on the reaction between CuO and the quaternary oxide (Mg,Co,Ni,Zn)O. A SEM analysis showed the formation of a product layer (Cu2MgO3-like) and a defective, less crystalline, diffusion layer. A high resolution XRD test proved to be effective in monitoring the structure (phases, distortion, cell parameter) across the interface, while producing the same compositions in powder form led to inconclusive results. As we observed from SEM a different distribution of elements, and even phases, ranging from short (up to 30 minutes) to long reaction times, we propose to investigate insitu the reaction of the DC at 1000°C. In comparison, we plan to investigate the DCs obtained by interrupting the reaction after a selected duration.

title: Raman X-ray spectroscopy of photo-dissociation of standard alcohol medium for high pressure experiments under x-ray irradiation

description: The intense x-rays available at EBS-ESRF are known to be able to trigger undesired effects, such as chemical modifications in radiation sensitive materials. Recently, we have observed the chemical dissociation of the alcohol solution used as pressure transmitting medium in high-pressure experiments. The reaction is complex, involving the production of liquid hydrogen and solidification of solids of unknown stoichiometry. To determine the nature of the different products of this speciation as a function of pressure, we propose to perform X-Ray Raman Spectroscopy in-situ within Diamond Anvil Cell, as this is the only technic allowing us to probe the absorption edges of low-z elements under pressure. A successful experiment will lead to the determination of the nature of the modified pressure transmitting elements as a function of dose and pressure, providing a comprehensive base for the high-pressure community to design experiments and avoid undesired sample-environment interactions.

title: Data from: The limited role of herbivorous fishes and turf-based trophic pathways in the functioning of turbid coral reefs

description: This data record contains data associated with the publication:Tebbett SB, Bellwood DR, Bassett T, Cuttler MVW, Moustaka M, Wilson SK, Yan HF, Evans RD (2024) The limited role of herbivorous fishes and turf-based trophic pathways in the functioning of turbid coral reefs. Reviews in Fish Biology and Fisheries 34:439-460. doi: 10.1007/s11160-023-09823-1In this study we examined herbivorous fishes and the nature of algal turfs (i.e. the epilithic algal matrix [EAM]) on turbid coral reefs across the Dampier Archipelago in northern Western Australia. The data analysed in this study included broad scale surveys (n = 30 sites) of herbivorous fish abundance in relation to long-term mean KD490 (i.e. a satellite-derived measure of turbidity). These broad scale data were collected using diver-operated underwater stereo video (stereo-DOV) or underwater visual census (UVC) on 30 or 50 m transects. Detailed quantification of the herbivorous fish community, including size estimation, was conducted at nine of these sites and were based on size stratified 30 m UVC transects. The nature of the EAM was quantified at seven sites (with algal turf length measurements at two additional sites). Four traits were quantified for the EAM (turf length, accumulated inorganic sediment load, percent of organic matter in total particulate load, and turf filament cover/density). Turf length was measured directly using callipers, while inorganic sediment load and particulate loads were quantified via vacuum sampling. Turf filament cover/density was based on photographs taken of the sampled area of EAM. For each photograph, 30 randomly stratified points were overlaid in the software photoQuad, and the presence of turf under each point was recorded. All data are based on shallow reef areas (generally ~1-3 m). Three CSV files are associated with this dataset. CSV File 1 contains the raw broad scale herbivorous fish abundance data and associated KD490 estimates. CSV File 2 contains the raw UVC data of herbivorous fish abundance and size estimates. CSV File 3 contains the EAM trait data (including turf length [mm], inorganic sediment mass [g m<sup>-2</sup>], relative organic matter load [%], turf filament cover/density [point count data]) as well as associated environmental variables (mean hydrodynamic velocity, mean significant wave height, and KD490).For full methodological details please see the published manuscript and associated supporting information (outlined above).
