title: µCt and virtual histology data of rat hind legs, Collagenase induced osteoarthritis rat model with experimental treatment (PMOXA)

description: Basic Setup:
This dataset includes samples from 40 rats, each contributing both hind legs. All rats receive a collagenase injection into the left knee to induce osteoarthritis (CIOA), while the right knee remains uninvolved by osteoarthritis induction and serves as an internal control. In addition to the collagenase, half of the animals recieve a treatment injection in both knees to allow analysis of local treatment effects and any potential impact on healthy joints. Samples are stained with a 1% phosphotungstic acid (PTA) solution in 70% ethanol for 22 hours before imaging to enhance soft tissue contrast.

Experimental Groups and Timeline:
All animals are divided into two treatment groups:

CIOA + Saline Group: Rats receive saline injections in both knees following collagenase injections into the left knee. This group serves as the control for treatment.

CIOA + PMOXA Group: Rats receive PMOXA (poly(2-methyl-2-oxazoline)) injections in both knees after CIOA induction. This setup allows evaluation of PMOXA’s therapeutic effect on the diseased joint and assessment of any unintended impact on the healthy (right) knee. PMOXA's properties and previous applications are described in the literature (https://doi.org/10.1021/acs.biomac.7b01828).

Each group is further divided based on the post-injection time point for euthanasia:

CIOA + Saline Group:
10 days post-CIOA (N = 10 per group)
60 days post-CIOA (N = 10 per group)
CIOA + PMOXA Group: 
10 days post-CIOA (N = 10 per group)
60 days post-CIOA (N = 10 per group)

Imaging and Documentation:
Knee joints are imaged using a Bruker 1272 µCT scanner, which provides high-resolution 3D visualization of bone and joint structures. Histological analysis is also performed to assess tissue-level changes. The accompanying readme file provides detailed imaging parameters.

title: Scent molecules encapsulated in zeolites: investigation to control their release

description: Fragrances and scent molecules find widespread application across various industries. However, a significant challenge encountered by the industry is the storage instability of these fragrances. A promising approach to mitigate this problem involves encapsulating the scent molecules within appropriate matrices, such as zeolites. In this experiment, therefore, we would like to explore the mechanism of scent molecule absorption into different zeolite matrixes and the release as a function of the temperature. Structural investigations depicting guest-host interaction are, indeed, necessary to tune and control the release. This can have important industrial/medical/agricultural applications to increase the use of essential oils instead of toxic chemicals.

title: Understanding variation in monotreme long-bone microstructures, and the emergence of marsupial reproduction

description: A sub-micron resolution synchrotron radiation-based X-ray computed tomography (SRCT) study of histological microstructures in the femora and humeri of extant monotremes and extinct Cretaceous mammals will pinpoint histological signatures of oviparity (egg-laying) vs. marsupial-like viviparity (live-birth) in the fossil record. We will test hypotheses that emerged from our previous experiment (LS-3244), in which we examined largely unknown bone-tissue microstructures of extant platypus and echidna and a variety of Mesozoic mammals. We discovered hitherto unrecognised histological variation within monotremes, and we did not detect a marsupial-like histological pattern in our Mesozoic mammal sample (counter to expectations). We propose to broaden our monotreme sample to understand the source of their histological variation (e.g., sex, ontogeny), and sample Mesozoic mammals from nearer the Cretaceous-Paleogene (K-Pg) boundary (66 Ma) when marsupial-like reproduction likely emerged.

title: Systematic study on the crystallization PEG / fatty acid (di-)triblock surfactants

description: The aim of this proposal is to collect synchrotron SAXS/WAXD based information on the semicrystalline structure development of double crystallizable PEG / fatty acid (di-)triblock surfactants with different length of PEG and fatty acids moieties. The distinguishable feature of double crystallizable block copolymers and surfactants is the potential crystallization competition between the blocks during cooling from the melt. The closeness of the PEG and fatty acids crystallization temperatures (Tc) should facilitate crystallization competition via the adopted cooling regime and by varying the PEG and fatty acid chain length. Trough the collected morphological data first insights can be gained on mechanistic aspects of crystallization competition in double crystallizable di(tri)block surfactants with close Tc as well as to understand its effect on final crystalline structure.

title: Exceptionally preserved fossils: new insights into early amphibian ecology and evolution

description: Amphibians are a diverse and ecologically important part of modern ecosystems, but the evolution of modern amphibian groups during the early Mesozoic is poorly understood due to a highly incomplete fossil record. Our fieldwork in the Jurassic of Scotland has recovered remarkable fossils with the potential to give fundamental new insights into the evolution and ecology of the earliest salamanders along with the oldest preserved albanerpetontid, an enigmatic amphibian group strongly divergent from modern amphibians. Due to their preservation in hard dolomite blocks, these specimens can only be studied using X-ray imaging. Pilot μCT scans have demonstrated the completeness of the material, but the resolution is insufficient because of poor noise-to-signal ratio and low contrast between bone and matrix. Synchrotron X-ray tomography can provide significantly improved resolution to observe the skeletal anatomy of these crucial specimens, providing critical new data about early amphibians.

title: Combinatorial study of role of interfacial energy on exsolution nanoparticle growth

description: Exsolution is a redox process that enables direct growth of anchored metal nanoparticles on metal oxide supports that show great promise for applications in catalytic and electrochemical energy conversion and storage technologies. The proposed experiment will utilize continuous compositional spread thin films with chemical gradients that adjust the structural and chemical properties of exsolution system, as well as different surface terminations. High-throughput screening by total scattering and X-ray absorption spectroscopy (XAS) will be applied to address unresolved questions of the role of strain in the host oxide and lattice mismatch to the exsolved metal nanoparticles, as well as the nucleation sites.

title: Effect of high power ultrasound on gels and the shear thickening transition

description: Acoustic vibrations may alter the properties of colloidal dispersions. In colloidal gels ultrasonic vibrations tend to soften the gel elasticity due to the formation of microcracks. Recent preliminary results obtained in our group have also shown that we can tune the properties of the shear thickening transition in colloidal dispersions with ultrasound vibration. In this proposal, we aim to mount on the saxs beamline our own rheometer coupled to an ultrasound transducer to investigate the effect of high power ultrasound (no cavitation) simultaneously on the mechanical and structural property of colloidal gels and colloidal shear thickening dispersions.

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: Se fate during sulfidation of Se-bearing ferrihdyrite: Effects of S/Fe ratios, carbonate and silicate

description: Determining how Fe-mineral-associated selenium (Se) behaves under sulphidic conditions can help predict its behaviour in near-surface conditions and identify biosphere exposure pathways for its radioactive analogue. This work studies how Se that was previously adsorbed on ferrihydrite behaves when ferrihydrite reacts with sulphides. Targeted batch experiments will first investigate whether Se is released back into solution or is retained in the solid phase, and how S/Fe ratios and the presence of inorganic impurities affects the extent and magnitude of Se release/retention. Using X-ray absorption spectroscopy (XAS) at the Se K-edge, this study will then determine if Se underwent redox changes, whether it formed discrete selenide compounds or if it was incorporated in sulphidation reaction products. Depending on the form of Se, its migration behaviour and potential biological uptake pathways are likely to be affected.

title: Pressure induced Eu-valence in EuRu2Ge2

description: The proposed experiment aims to investigate the pressure-evolution of europium valence in EuRu2Ge2 intermetallic compound. EuRu2Ge2 orders ferromagnetically below TC = 62 K. When pressure was applied, the character of the resistivity curve rho(T) shows peaks with character signifying pressure-induced valence transition at about 4-6 GPa. As a hint of valence change, we have performed a compressibility test using in-house experiment of XRD under pressure at room temperature. This measurement showed a sign of compressibility change at about 7-8 GPa. XAS is a unique tool enabling to discriminate the valence state of the magnetic europium atoms. If the valence change will be experimentally confirmed, it will represent first example of pressure-induced valence transition in ferromagnetic Eu-compounds.

title: Studying the long-wavelength dynamics in glass-forming liquids

description: We propose to study the long-wavelength dynamics in glass-forming liquids using small-angle XPCS at ID10. The dynamics in glass-forming liquids shows a rich behavior depending on the length scale being considered. In particular, the intermediate Q-range between the hydrodynamic limit (Q -&gt; 0) and the structure factor maximum (corresponding to interatomic distances) is largely unexplored and in need of experimental data for a better understanding. The successful operation of EBS should greatly facilitate XPCS measurements in this Q-range where scattering is weak. We propose to measure and compare several different metallic glass formers with various compositions, in order to disentangle the effects of concentration and density fluctuations on the dynamics of glass-forming liquids.

title: Cortical neural development in health and disease

description: Understanding how the mammalian brain develops is the sine qua non condition for deciphering neurodevelopmental disorders (ND), a condition characterized by an abnormal brain development in utero and leading to intellectual and/or motor disabilities in juveniles. The main structure affected in ND is the cerebral cortex. It is composed of six layers of neurons that are sequentially generated from progenitor cells (PC) during embryonic life. This patterning if altered results in malformations of cortical development (MCD) associated with ND clinical manifestations. Despite progress in MCD diagnosis, the cellular mechanisms regulating the sequential acquisition of PC identity and the orderly buildup of cortex remain poorly understood. Based on MCD mouse model and promising results obtained on X-ray holographic nanotomography on embryonic cortex slices, this proposal aims to continue the coordinated study of PC structure and physiology in health and disease.

title: Sr diffusion from fillings into the tooth dentine biocomposite: nano-imaging and nano-XRF/XRD tomography for mapping chemical changes around

description: Sr-containing dental filling materials such as glass-ionomer cement are widely used for tooth restorations. Already weeks after placement long-range passive diffusion of Sr ions into the mineralized dentine matrix is detected. We examine to what extent this diffusion alters the properties of dentine and its resistance to degradation. Because dentine contains µm diameter tubules and is rich in mineral crystals of Ca and P, we need high resolution/energy nanoprobe to be able to identify Sr deposits. We propose to map the micro-chemistry of dentine using high flux nm sized beams, coupled with PCE nano-CT imaging. Nano-XRF in combination with XRD will reveal Sr in relation to the tubules and will disclose changes in the mineralized fibers and apatite nanocrystals lattice parameters. The high-resolution imaging capacities of ID16B are needed to identify diffusion paths of Sr in dentine facilitating the assessment of the clinical use of Sr leaching out of dental filling materials.

title: Combined SXRF and SXRD study of Ca-rich phases from NASAs OSIRIS-REx sample return mission from asteroid Bennu

description: First analyses of the pristine asteroid material collected from the surface of the dark, carbonaceous asteroid 101955 Bennu by NASA’s OSIRIS-REx spacecraft have reported widespread abundance of hydrated minerals and organic material [1]. Up-to-now we mainly applied high-energy (90 keV) synchrotron X-ray fluorescence (SXRF) spectroscopy to investigate the concentration levels of rare-earth elements (REEs) in Ca-phosphates and carbonates, both products of aqueous alteration. Our results [2, 3] indicate higher REE levels in Bennu material relative to material collected from the surface of the similarly dark, carbonaceous asteroid Ryugu [4, 5]. Unambiguous identification of the analysed REE-bearing mineral phases (inferred to be Ca-phosphates and carbonates), planned by this experiment, will be essential for accurate interpretation of our data and their implications for the processes of aqueous alteration on ancient carbonaceous asteroids.

title: Mercury speciation in environments impacted by gold-mining activities

description: In Amazonia, anthropogenic activities like Artisanal and Small-scale Gold Mining (ASGM) have been involved in Hg pollution but the exact extend of contamination is difficult to assess. A binary mixing model with Hg isotopic composition is commonly used to show the contribution of anthropogenic Hg in river sediments and soils. However, some of higher concentrated samples, expected to contain mainly anthropogenic Hg do not follow this binary model. On the other hand, other samples following this model show high degree of contamination but with low Hg concentrations which it is not consistent with the literature. Consequently, the accuracy of this binary model is questioned. In this project we propose to study Hg speciation in various samples related to ASGM. We aim to investigate Hg oxidative state and bearing phases to refine our understanding of Hg mobility from tailings and pristine sources in order to have a better insight of the isotopic composition.

title: X-ray Raman scattering, X-ray emission and optical spectroscopy of matter at extreme conditions: Structure of melts and molecular compounds

description: This long term project aims for the implementation of a power-stabilized CO2 laser heating setup coupled to diamond anvil cell technique and optical Raman spectroscopy at the X-ray Raman spectrometer of beamline ID20 of ESRF. This instrumentation will enable unique in-situ studies of low-Z element compounds at extreme conditions, extracting information of local and long-range structure as well as electronic properties of disordered matter. We aim to explore silicate glasses and melts in order to reveal the structure and electronic state of relevant magmas. Second, we will investigate the chemistry of the light compounds H2O, CO2 and NH3 at extreme conditions which is highly relevant for the dynamics and formation of giant-gas and most exoplanets. The setup will significantly extend the capabilities of beamline ID20 and cross not only new frontiers in geoscientific applications but addresses likewise a broad user-base in diverse areas such as chemistry, physics and materials science.

title: New green carbon fibres made from lignin: In-situ study of their graphitization by X-ray scattering

description: Carbon fibres are widely used in industries such as aerospace, automotive, and sports equipment due to their lightweight nature and exceptional mechanical properties. However, the conventional production of carbon fibres relies on petrochemical precursors such as polyacrylonitrile (PAN) polymer. This proposal aims to explore lignin, a plant-derived polymer, as a sustainable alternative precursor for carbon fibre production. Its objective is to investigate in-situ, as a function of temperature, the structural and textural transformations that occur during the thermal conversion of lignin fibres into carbon fibres. Understanding these transformations is crucial for enhancing the graphitization process, which is a key determinant of the mechanical properties of the final carbon fibre.

title: Grazing Incidence X-ray Scattering for Enhanced Solar Energy Harvesting

description: Here, grazing incidence X-ray scattering (GIXS) will provide new insights into the molecular self-assembly of small molecule organic semiconductor (OSC) and colloidal quantum dot (QD) films for emerging energy harvesting technologies. The proposed experiments involve both ex-situ and in-situ GIXS to expand our understanding of the relationships between materials processing &lt;&gt; film morphology &lt;&gt; optoelectronic performance. Time on XMaS is requested to enable real-time, high-resolution characterisation of the thin film molecular assembly during and after processing, paving the way for the rational design of processing routes to obtain targeted morphologies.

title: Operando spectroscopic Bragg-CDI of Ni Alloyed Nanocrystals during CO2 Hydrogenation

description: The catalytic hydrogenation of CO2 has become increasingly attractive for the use of this greenhouse gas as an economical source of C1 carbon. Nickel (Ni) is one of the most commonly used catalysts due to its relatively high activity and economic viability compared to the noble metals. With spectroscopic Bragg Coherent X-ray Diffraction Imaging (spectro-BCDI), a state-of-the art characterisation tool, we aim to reveal both the structural (lattice strain, defect(s), facets and morphology) and chemical (composition and oxidation states) characteristics of Ni and alloyed Ni-Fe catalysts. We will create guidelines for the design of both efficient and selective catalysts for CO2 hydrogenation. The effect of alloying and support-catalyst interaction will also be evaluated.

title: Kinetics of He bubble growth in tungsten oxide layers: a parametric study

description: In future nuclear fusion reactors, the first physical barrier facing the plasma will be strongly irradiated by helium atoms generatingmany defects at the materials surface. In that respect in operando grazing incidence small angle x-ray scattering (GISAXS) and grazingincidence x-ray diffraction (GIXD) during implantation of ions into crystals are very powerful techniques to probe these alterationmechanisms. In this proposal we aim at studying the helium bubbles growth processes and train field in tungsten oxide under heliumimplantation and in a wide range of temperatures (room temperature up to 1400°C) by combining, in real-time, GISAXS and GIXD available onINS2 setup (BM32-ESRF).
