title: Insight into the local coordination environment of water to sodium in Prussian White using neutron total scattering

description: Prussian Blue Analogues (PBAs) are an interesting class of material to use as cathode material in Na-ion batteries, in particular, the Fe-based vacancy-free Na-rich PBA, known as Prussian White (PW, Na2Fe[Fe(CN)6]·zH2O), is a promising candidate. PW exhibits a near room temperature phase transition from P21/n to R-3, which is due to an octahedral tilt transition. In the P21/n model, the water is randomly distributed in a plane, while the ordering of the water is lost when transforming to the R-3 structure. Thus, we propose a neutron total scattering experiment to determine the position of water and the local coordination environment of Na in both room temperature structures as it was not possible from the average structures. The results will aid the understanding of the origin of the octahedral tilt transitions and the role that water plays in these tilt transitions in PW.

title: Unconventional superconductivity in a highly two-dimensional organic charge transfer salt

description: Although many organic superconductors can be produced via charge transfer salts of the organic molecule BEDT-TTF, the new compound β″-(BEDT-TTF)2[(H2O)(NH4)2Cr(C2O4)3]·18-crown 6 with superconducting onset at 4 K stands out as having a particularly strong 2D character due to an unusually thick anion layer separating the metallic BEDT-TTF layers. This produces an extremely good example of a highly anisotropic superconductor whose 2D superconducting vortex properties are expected to be well described by Berezinskii-Kosterlitz-Thouless physics. Existing data on the upper critical field for in-plane field orientation exceeds the Pauli limit at low temperature, pointing towards an unconventional character for the superconductivity. This proposal will use TF-muSR to explore the superconducting phase diagram and the vortex properties of the mixed state of this novel superconductor and compare its properties against those of other molecular organic superconductors.

title: Probing lattice oxygen coupling in metal oxides for oxygen evolution reaction catalysis

description: The oxygen evolution reaction (OER) is the key half-reaction for a range of highly relevant electrocatalytic processes, such as water splitting or CO2 reduction. It was reported, that an alternative OER mechanism could take place in some metal oxides through the direct activation and coupling of lattice oxygen atoms (lattice oxygen-mediated mechanism, LOM), which can offer notably higher reaction rates than the conventional adsorbate evolution mechanism of OER. However, there is a significant lack of understanding on how LOM is activated in metal oxides. In this study, by using atomic pair distribution function analysis (PDF) analysis of total neutron scattering, we plan to probe the local atomic structure of the Co-based perovskite oxides, which have demonstrated one of the highest reported catalytic performances in OER. Precise structural characterization will allow to identify reduced O‒O distances (including the presence of O‒O peroxo-like dimers, trapped molecular O2, etc.) which can be indicative of the LOM OER. The identification of the oxidized oxygen species (e.g., in form of (O2)n‒ dimers (4 &gt; n ≥ 0)) in the oxide lattice would provide the first direct structural evidence for the involvement of oxygen redox in the OER mechanism, constituting a crucial advancement in the area.

title: Investigating the origin of the phonons short mean free path in BaBiO3

description: The perovskite BaBiO3 displays a complex phase diagram as a function of temperature and doping, offering a rich playground to explore the role of phonons on the emergence of collective quantum states. BaBiO3 was recently predicted to host topologically protected metallic surfaces, also pointing to the potential of this material as a thermoelectric candidate. In this context, our recent transport investigation in BaBiO3 revealed a low value of thermal conductivity ~ 1W/mK, leading to an estimated phonon mean free path at room temperature of the order of the unit cell and suggesting the presence of scattering mechanisms limiting phonon transport. In this proposal, we propose to perform SXD to investigate the role of static and dynamic defects to advance our understanding of the microscopic mechanisms at the base of the transport properties.

title: Examining the Effect of Pancratistatin on Lipid Packing in Live Cancerous and Non-cancerous Mitochondria.

description: This work investigates the differences in lipid packing of non-cancerous and cancerous mitochondrial membranes when exposed to pancratistatin (PST), a natural cancer drug candidate, to elucidate its fundamental mechanism of action. PST is very promising as a novel therapeutic as it has demonstrated specificity towards human cancerous cells (breast, colon, lymphoma) and explicitly targeting the mitochondria of cancerous cells and initiating apoptosis, leaving healthy cells unscathed. However, due to the lack of experimental evidence, the mechanism of PST is poorly understood. Above all, the mechanistic pathway must first be elucidated and understood to progress this drug candidate. Biological membranes, such as those in the mitochondria, play a significant role in regulating physiological processes such as signalling and apoptosis. Membranes have a high degree of spatial organization which plays a critical functional role in the life of a cell. More specifically, lipid packing within lipid bilayers is key to the physiochemical features of membranes and has been shown to be involved in many processes. Thus, the breadth of this research revolves around the study of understanding the complex questions surrounding how PST targets cancerous cells and the development of novel methods to rapidly differentiate between healthy and cancerous tissue using advanced, modern probe-free methods such as neutron scattering.

title: Structure of Fe-based Li/Na hybrid Prussian Blue Analogues

description: Prussian Blue Analogues (PBAs, AxM[M'(CN)6)]·zH2O) are a promising class of materials for sustainable positive battery electrodes, especially Prussian White (Na2-xFe[Fe(CN)6]) due to its high theoretical capacity (160-170 mAh/g) and high operating potential (~3.2 V). However, the material shows significant capacity fading due to the volume collapse of the framework during electrochemical cycling. It has been proposed that this can be resolved by the removal of the phase transition of the material by replacing some Na-ions with Li-ions. The question remaining is how much Li is required to prevent the phase transition from occurring. The structure of PBAs highly depends on the alkali cation size with structural distortions observed for larger cations. Thus, neutron diffraction on a range of compositions of Li/Na hybrid PBAs is required to determine the structure of Li-based PBAs, the positions of Li/Na within the structure, and confirm the existence of tilt distortions in Li-based PBAs. This will aid the understanding of tilt transitions in PBAs and subsequently how to manipulate these to improve the material performance.

description: In this experiment we propose to investigate, by ToF-ND (Time of Flight Neutron Diffraction), samples taken from a life-size Greco-Roman bronze torso from the collection of the Museo Archeologico Nazionale di Firenze (MAF), in order to characterize the compositional microstructural features related to the casting process. A microstructural analysis of the samples from different areas of the statue will provide us with important information related with the composition of the bronze alloy, hints about the casting methods, and an assessment of the statue conservation status in the areas where the samples have been taken.

title: Determination of magnetic ground state in the trimer based mixed valent hexagonal perovskite ruthenate Ba4NbRu3O12 using powder neutron diffraction

description: The trimer based 12L-hexagonal quadrupole perovskites Ba4MM’3O12(M=di, tri, tetra, and pentavalent cation; M’=heavy transition metal Ru, Rh, and Ir) serve as a potential avenue for various intriguing magnetic ground states due to a delicate balance between spin-orbit coupling (SOC) of 4d/5d transition metals, crystal field splitting, intra & inter-trimer magnetic exchange interactions, and geometric frustration. Ba4NbRu3O12 has recently been reported to be a geometrically frustrated Mott insulator, showing apparent quantum spin liquid like signature in both the high-field dc magnetization and heat capacity data, as well as T-linear contribution to the magnetic specific heat at very low-T. However, appearance of a ZFC and FC peak around 4 K in the 100 Oe susceptibility data, and a ZFC/FC irreversibility together with a broad hump-like anomaly in the magnetic specific heat in the 7-10 K temperature range, indicate a possible magnetic ordering. To shed light on the ground state of this material, we are going to undertake neutron powder diffraction measurements using the high-resolution cold neutron diffractometer WISH

title: Kraft Lignin Solubility in Deep Eutectic Solvents

description: Lignin stands as a promising raw material to produce commodities and specialty chemicals, yet its poor solubility remains a big challenge. Recently, deep eutectic solvents (DES) have been proposed as sustainable solvents with high potential to dissolve and valorize lignin. In the present study, the ability of DES based on cholinium chloride (ChCl) combined with alcohols and carboxylic acids as hydrogen bond donors to dissolve kraft lignin is examined. The main goal is to get insights on the importance of the water content on the solubility of kraft lignin in DES. Inelastic neutron scattering (INS) will be applied to unravel the DES-water-lignin interactions at a molecular level.
