title: Self-assembly of novel catechol-containing copolymer in non-polar media: Nano-clustering and nano-emulsions

description: We propose a SANS study in collaboration with Infineum, a world-leading lubricant and fuel additive manufacturer, to examine the self-assembly behaviour of novel catechol-containing polymer additives in a non-polar solvent, and the effects of temperature and added water. Mussel-inspired catechol-containing copolymers have a diverse range of potential applications arising from the intra- and inter-molecular interactions enabled by the catechol group (i.e. 1,2-dihydroxybenzene) including hydrogen bonding, π-π stacking, and metal-ion coordination. How such interactions underpin self-assembly of catechol-functionalized polymers in non-polar media is of fundamental interest and also critical to their potential applications, but remains poorly understood.We have previously investigated the self-assembly behaviour of a series of catechol-containing copolymers in dodecane, pointing to possible clustering of the primary nanostructures. We now wish to investigate the self-assembly behaviour of nano-emulsions formed using this series of polymers. These results will inform the development of future applications of these polymers as well as aid in the interpretation and fundamental understanding of data gathered on these polymers using other techniques including X -ray reflectivity (XRR) and surface force apparatus (SFA).

title: Au quantum dots with partial and mixed surfactant ligand shells

description: Small angle neutron scattering (SANS) will be used to probe the structural differences in mixed ligand and deficient ligand shells on Au quantum dots. The project goal is to develop Monte Carlo simulations to fit scattering data from ligand shell structures on LS-QDs and to simulate their eventual self-assembly interactions in bulk fluids, at interfaces and in nanocomposites. This offers a promising avenue towards increased understanding of ligand shell morphologies and the effects of shell structure on self-assembly, enabling rational approaches in tuning material properties without necessarily requiring chemical variation. High-quality small angle scattering data will also inform the development of Monte Carlo simulations that can provide new fundamental insights into the self-assembly interactions between LS-QDs.

title: Pressure induced structural transformations in Jadeite glass

description: The glass-ceramic processing route, by which controlled crystallisation occurs in a glass matrix, provides the preparation pathway for a host of moldable fracture-resistant materials. Here, jadeite (NaAlSi2O6) provides exceptional fracture toughness and offers the possibility of manufacturing glass-ceramic materials with exceptional resistance to crack propagation via high pressure and temperature processing. We propose to investigate the structure of jadeite glass by in-situ high-pressure neutron diffraction to provide benchmark results for the structural transformations that occur. Knowledge of these transformations is essential for predicting the conditions under which the local coordination environment of Al matches that of the crystal, thus facilitating the desired crystal growth. The results will elucidate the mechanisms of densification where oxygen triclusters will play an important role. Hence, the experiment will provide key information for guiding in the development of the glass-ceramic route to ultra-high-toughness materials.

title: Origin of the topological/unconventional Hall effect in Quaternary Heusler alloy NiCoMnAl.

description: Non-trivial spin configurations such as skyrmions and anti-skyrmions have gained attention owing to their importance from fundamental and technological perspective. Heusler alloy is one such family of compound with promising characteristics for exploring and controlling topological phases. Albeit of existing literature on topologically spin structures in full and inverse Heusler compound, the subgroup of quaternary Heusler alloy remains unexplored. In this study, the novel quaternary Heusler alloy NiCoMnAl is interesting as the obtained saturation moment deviates from the theoretical prediction. The ac susceptibility measurement also reveals the presence of non-coplanar (NPL) spin textures before the field polarized phase. The transverse resistivity measurements reflect the presence of non-trivial spin arrangement where an additional component [i.e. topological Hall resistivity (THR)/unconventional Hall resistivity (UCHR)] with anomalous Hall resistivity (AHR) arises in a temperature range of 2-380 K, with a considerable value of 2.5µΩ cm at 300 K. We propose to investigate the magnetic spin configuration of polycrystalline NiCoMnAl in zero-field as well as in presence of external applied magnetic fields in the wide temperature range to confirm the formation of topologically protected textures and skyrmion lattice formation by SANS experiment.

title: Magnetic excitation in buckled honeycomb compound gamma-Co2P2O7 with Kitaev magnetism

description: We propose to perform inelastic neutron scattering on buckled honeycomb compound gamma-Co2P2O7. Honeycomb cobaltates have been studied as a candidate of Kitaev spin liquid, but some of them have been shown to have predominant Heisenberg coupling, rather than Kitaev coupling, due to direct t2g hopping. To realize a Kitaev-dominant magnet, we focused on gamma-Co2P2O7 which has much larger Co-Co bond length than those of other honeycomb cobaltates, likely suppressing undesired Heisenberg coupling. gamma-Co2P2O7 shows two magnetic transitions at low temperatures. By increasing magnetic fields, the transitions are gradually suppressed and a spin-liquid-like behavior is seen above 7 T. However, we don't have detailed information about underlying magnetic interactions. We therefore plan to study the magnon dispersion by INS and extract relevant magnetic interactions.

title: Deconvoluting sub-populations of vesicles in lipid nanoparticle formulations

description: Lipid nanoparticles (LNPs) and vesicles are emerging classes of novel therapeutics. However, LNP formulations possess many different internal structures, and particle structure heterogeneity within samples, including sub-populations of vesicles produced as a by-product during formulation. This causes significant challenges when evaluating LNP activity in biological systems, as it is almost impossible to decouple the activity due to the LNP population and the vesicle sub-populations. Also, challenges characterising LNP internal structures in heterogeneous populations mean there is currently very limited ability to determine and apply structure-activity relationships to design new active formulations. 
Here, we will use SANS to systematically characterise structural variations in LNP and vesicle formulations, and mixtures thereof. Next, we apply this knowledge to characterise vesicle sub-populations natively present in specific LNP formulations. Using asymmetric flow field flow fractionation, we will separate these sub-populations, and study their individual contributions to the full sample. 
We will combine models we have previously used, and LNP/vesicle starting structures being developed within the ShapeSpyer programe, with which we can simulate scattering curves for pure LNP and vesicle systems and decouple any eventual mixing-mediated changes to the morphologies of particle sub-populations. The data contributes to informed design of LNPs for medical applications.

title: Spin liquid behaviour in the single-layer Ising triangular lattice antiferromagnet YbTa7O19

description: The compound YbTa7O19 consists of triangular layers of antiferromagnetically coupled Yb3+ spins and shows no sign of magnetic order at temperatures down to 2 K. It is a candidate spin liquid compound and the aim of this muon study is firstly to test to see whether it remains in a fluctuating state down to milliKelvin temperatures, and secondly to use longitudinal field measurements to probe the spin correlation function and test against models of spin diffusion in frustrated systems.

title: Engine-X Neutron Diffractometer Measurement of ‘2 in 1 Intumescent Coating in Geopolymer Plaster’ as Fire Protection Materials Towards Interfacial Bonding Mechanism Approach

description: Plaster is indispensable for coating, preserving, and beautifying interior walls and ceilings. Its crucial role extends to fire resistance, safeguarding against the spread of combustible materials and protecting concrete structures from irreversible damage. Intumescent coating, containing fire-resistant chemicals, expands under high heat, forming a protective layer. Combining plaster with fire protection yields numerous benefits, yet attention must be paid to the base material's integrity specifically on coating. Geopolymer, renowned for thermal stability and fire resistance, emerges as a promising choice. While plaster can serve as an intumescent coating, additional layers may be necessary for comprehensive fireproofing. Current research predominantly enhances coating properties with OPC, leaving a gap for exploring geopolymer's performance. This study aims to scrutinize geopolymer coating's behavior under high temperatures, employing neutron diffraction to evaluate phase changes and deformation mechanisms. In-situ compressive and tensile tests, reaching temperatures up to 900°C, will provide crucial insights. Morphological, chemical, and weight loss analyses will complement the mechanical data, elucidating material responses to thermal stress. This investigation fills a significant research void, promising invaluable insights into fire-resistant coating applications.

title: In-situ time-resolved SANS and ND study of the random VC precipitation kinetics in Nanosteels

description: Nano-steels are a new generation of Advanced High Strength Steels (AHSS), extremely suitable for lightweight
automotive applications. The matrix of the steel, which provides ductility and stretch, is significantly strengthened by
manometer-sized precipitates, which can increase the strength level by 30-50%. These steels contain different microalloying
additions, such as vanadium (V), which form the essential nano-precipitates. A resource-efficient use of these alloying additions requires further knowledge on the formation kinetics of these nanometer-sized vanadium carbides (VC). The formation of these nano-scale VC precipitates can be achieved by two mechanisms: (a) random precipitation from supersaturated ferrite and/or (b) interphase precipitation. Our previous studies have focused on interphase precipitation. In this experiment we want to explore random precipitation. Our aim is to measure the random VC-precipitation kinetics in Nano-steel by simultaneous in-situ time-resolved SANS and Neutron Diffraction (ND) at elevated temperatures to elucidate the effects of V and C additions.
