title: Self-assembly of glycerol monooleate micelles with scientifically and industrially relevant organic additives

description: Friction modifiers are a critical component of engine oil formulations and serve to reduce the abrasive damage and energy losses between two contacting surfaces. As a result, the surfaces remain intact for much longer time periods (engine lifetime) and fuel efficiency increases dramatically. Organic friction modifiers are conventionally molecular surfactants, thus their capacity for partitioning from the bulk oil phase to the metal surface is dependent on an interplay of interactive forces. Therefore, understanding self-assembly behaviour under different solution conditions and in the presence of different chemical species (additives) is a key factor in the design and deployment of these systems. In this work, we will investigate the self-assembly of glycerol monooleate - a widely used organic friction modifier - in dodecane with different, systematically varied organic additives by small angle neutron scattering. These measurements will allow monitoring of structural evolution of the micelles in response to the additive chemistry and concentration. We anticipate that changes are likely to drastically alter friction modification. Hence, these findings may offer new approaches for the design and control of cheaper and more effective engine oil formulations that will significantly reduce cost and emissions.

title: Deformation Behaviour of Novel BCC-Superalloys for High Temperature Application

description: A range of body-centered cubic (BCC) superalloys for high-temperature applications are being developed by the Materials for Extreme Environments group at the University of Birmingham. In this proposal, we intend to perform in-situ loading experiments on Cr-, Fe- and W-based BCC superalloys strengthened by coherent B2 intermetallic nanoprecipitates. This study aims to investigate the phase evolution and optimal value of lattice misfit for increasing the load transfer from matrix to precipitates and combat softening at high temperatures. The in-situ compressive loading experiments will be conducted from room temperature to 900 C at Engin-X. The results of this study will provide insights into the micromechanical behaviour of these novel alloys.

title: Inelastic Neutron Scattering Study of Crystal Field Excitations in spin-chain compounds K2RENb5O15 (RE = Ce, Pr, Nd)

description: K2RENb5O15 (RE = rare earths), which form in tetragonal tungsten-bronze structure, display interesting magnetic properties arising from 1D linear spin-chain of RE3+ ions along the c-axis. The magnetic susceptibility measurements show absence of long-range magnetic ordering in K2RENb5O15 with RE = Ce, Pr, Nd down to 1.8 K. The fit to high temperature susceptibility gives Curie-Weiss temperature of -94.5 K, -62.2 K and -70.3 K for RE=Ce, Pr and Nd, respectively. However the low temperature susceptibility reveals the dominant ferromagnetic correlations for Ce and Nd, and dominant antiferromagnetic correlations for Pr. The isothermal magnetization reflects significant reduction in saturation magnetization due to strong crystal electric field (CEF) effect. Information about the CEF excitations is highly desired to understand the relation between the CEF and magnetic properties of these compounds. We therefore propose to carry out inelastic neutron scattering measurement on K2RENb5O15 (RE = Ce, Pr, Nd) using MARI

title: Magnetism in tetragonal and cubic Mn2TiO4 single crystals

description: The compound Mn2TiO4 crystallizes in two different forms tetragonal and cubic phases respectively. The cubic inverse spinal can be thought of as "Mn2+(Mn2+/Ti4+)O4 and exhibits a ferrimagnetic transition with no compensation transition. The B site is partially occupied by non-magnetic Ti4+ and the magnetism is associated with an S = 5/2 network of Mn2+ ions distributed over half of the B sites and the A site. Our single crystal samples are characterised using powder and single crystal x-ray, magnetometry and heat capacity. Our tetragonal phase ferrimagnetic magnetisation transition is very sharp and ruled out any mixed magnetic ions. We propose to study the magnetism in both tetragonal and cubic phases using muon relaxation which was not previously been reported.

title: The Structure of Vanadium-Tellurite Glasses

description: We wish to better understand the interaction between the two network formers, V2O5 and TeO2 in tellurite glasses. The aim is to relate the structural changes in the glass to changes in functional properties such as Tg, density, electrical properties, and optical properties. In addition, the data will be used in an ISIS facilities development studentship to develop coordination constraints in the Dissolve software to better simulate the structure of glasses. This study will measure a series of vanadium-tellurite glasses, across the glass-forming region, using neutron diffraction. A combination of direct fitting, simultaneous fitting with X-ray data (I-15-1), and computational analysis will be used to determine the tellurium-oxygen coordination number, nTeO, and the vanadium-oxygen coordination number, nVO with composition. These results will then be used to develop structure-property relationships for this glass series.

title: A combined SANS-Neutron reflectivity study on RNA nanocomplexes formation and aerosolisation for pulmonary delivery_SANS

description: There is a growing interest in developing RNA therapeutics such as small interfering and messenger RNA o treat respiratory diseases. However, RNAs are notoriously unstable, rendering their delivery extremely challenging. Currently, RNA delivery is limited to parenteral administration with poor lung distribution. A safe and effective pulmonary delivery system that allows the direct application of RNA therapeutics to the site of action in the lung would be critical to extend the applications of RNA therapeutics to lung-related diseases. Furthermore, inhaled mRNA vaccine could improve efficacy against respiratory infections by triggering mucosal immune response in a non-invasive manner. Recently, our group has successfully developed a biomimetic PEGylated KL4 peptide (patent pending) which is demonstrated to be a safe and effective non-viral vector for RNA delivery to the lung. The overall aim of this study is to analyse the structural characteristics of the PEGylated KL4/ RNA nanocomplexes systematically using different size of RNAs, and to monitor the structural stability of the nanocomplexes during nebulisation. The outcomes of the study would provide valuable insights that allow us to optimise and tailor an inhalable/aerosolised PEGylated KL4 peptide based RNA delivery applicable for a wide range of RNA therapeutics.

title: Investigation of incommensurate structures in β-NaFeO2

description: β-NaFeO2 has attracted attention as a candidate for multiferroic at room temperature because of its ferroelectric crystal structure and antiferromagnetic ordering at room temperature. However, the crystal structure as well as the magnetic structure remain unclear. To establish a proper symmetry for crystal and magnetic structure we have proposed a neutron powder experiment using WISH instrument (Proposal Reference No: 2420045). Additionally, our magnetization measurements for β-NaFeO2 single crystal show an indication of new antiferromagnetic transitions below 120 K. Due to the magnetoelectric couplings associated with those transitions, an incommensurate structure might be established and might correlate to the multiferroic properties in β-NaFeO2. Here, we propose a single crystal diffraction experiment to verify the existence of incommensurate structures between the antiferromagnetic orderings at low temperatures. The result will be useful for understanding the magnetoelectric coupling supporting multiferroic systems, particularly NaFeO2 compounds.

title: We CANS Do It: A Step Towards a Canadian PC-CANS

description: With a shortage of neutrons worldwide, a desire for the development of compact accelerator-driven neutron sources (CANS) has arisen. As such, a prototype Canadian CANS (PC-CANS) is proposed as the first steps towards rebuilding Canadian neutron capabilities. A challenge for this project is demonstrating that such a build will yield useful and efficient measurement capabilities for the user community. To emulate the proposed PC-CANS capabilities, the use of a modified LOQ setup (modified aperture) with a lower neutron flux will be used to measure a variety of experiments to compare the quality of data received versus a native LOQ setup. The experiments planned for the beamtime would include lipid membrane experiments probing structure of vesicles, detection of lipid domains, and monitoring of lipid asymmetry. Further experimentation in other fields, such as a templated silicalite experiment, will also be performed to expand the scope of the investigation and display further capabilities of the CANS instrument to users of other disciplines.

title: Operando Neutron Diffraction Study of the Structural Degradation Mechanisms in Industrial Multi-Layer Stacked Li-ion Battery Pouch Cells

description: Operando neutron diffraction is ideal for probing structural changes in Li-ion battery electrodes such as graphite and Li transition metal oxides. Their sensitivity to Li, C and O, coupled with their ability to distinguish Ni, Mn and Co make it particularly suitable for studying bulk structural changes that underpin the electrochemical degradation in Li-ion batteries. However, they are often studied using modified bespoke electrochemical cells with (expensive) deuterated electrolytes and 7Li-enriched cathodes, that are far removed from conventional operating conditions. Hence, the results obtained can often not be directly transferred to real-world operations, thereby restricting their applicability. In this proposal, we intend to perform operando neutron diffraction studies of machine-fabricated multi-layer pouch cells built on the industrial pilot line at WMG, Uni. of Warwick, which have not been modified to aid neutron transmission. The increased thickness of these multi-layered cells preclude X-ray diffraction studies, rendering neutron diffraction as the only probe for electrode structural changes. Crucially, as confirmed through preliminary XPress access data, the high mass loading and machine-built quality of the cells permit high-quality diffraction data to be obtained from Polaris using these cells, without having to use deuterated electrolytes or isotope-enriched materials.
