title: Inelastic Neutron Scattering Investigations of CEF excitations in Ce3TiAs5

description: Ce3TiAs5 form in a hexagonal structure (space group of P63/mcm) consisting of zig-zag chains of Ce atoms along the c-axis because of which an anisotropic Kondo effect is anticipated. Magnetic susceptibility, electrical resistivity and heat capacity data of Ce3TiAs5 show anomalies associated with a magnetic phase transition of antiferromagnetic nature at TN = 13 K, and resistivity presents Kondo lattice behaviour which together with an enhanced Sommerfeld coefficient characterize Ce3TiAs5 as a Kondo lattice heavy fermion system. We have investigated Ce3Tias5 3g powder sample synthesized using high pressure on EMU and WISH. Both these experiments revealed a long range magnetic ground state below TN. Further investigations using the inelastic neutron scattering experiment are highly desired to probe the spin wave and CEF excitations in this compound. We propose to carry out inelastic neutron scattering (INS) measurements on Ce3TiAs5 using the spectrometer MERLIN/MARI to determine the crystal field level scheme and spin wave below TN in the express mode. The INS results from MERLIN/MARI along with WISH and EMU results will give a high impact publication on this quasi-1D Ce-chian compound.

title: High temperature transmission measurements of graphite, SiC, ZrC, and MgO

description: This research aims to measure the temperature-dependent transmission, i.e. total cross sectio, of graphite, silicon carbide (SiC), zirconium carbide (ZrC), and magnesium oxide (MgO) using the VESUVIO beamline at ISIS. These materials are crucial for advanced high-temperature nuclear reactor designs, as identified in recent US DOE/NRC collaborations. Current Evaluated Nuclear Data File (ENDF) libraries, which provide critical data for reactor design and safety analysis, contain inaccuracies in thermal scattering laws (TSLs) due to modeling errors, especially for materials like nuclear graphite with varying porosities. Our preliminary work includes room temperature transmission measurements of different grades of nuclear graphite, and phonon spectrum measurements at 5 K and 296.3 K for SiC, ZrC, and MgO, as well as atomistic calculations to predict their behavior at elevated temperatures. We propose to extend these measurements up to 900 C to provide accurate experimental data for validating and improving TSLs in ENDF.

title: Effect of formulation method and lipid composition on lipid distribution across membrane leaflets in asymmetric lipid vesicles

description: Lipid-based delivery systems such as liposomes face challenges such as low encapsulation efficiency, immunogenicity and limited endosomal escape hinder the widespread adoption of liposomes as delivery vehicles. To improve their efficacy, attempts have been made to adapt them to mimic extracellular vesicles (EVs), which are produced by cells for communication and have desirable characteristics including innate biocompatibility. We hypothesise that EV membranes, like the cell membranes they are derived from, have different lipid distributions in their inner and outer leaflets (i.e. are asymmetric). This asymmetry affects EV biophysical and biochemical properties - however, methods to formulated asymmetric vesicles on large length scales have limited control over lipid composition and size, selectivity towards certain phospholipid headgroups, and low throughput. In this proposal, we address these limitations by comparing the chemical and physical properties of vesicles formulated with a range of lipid compositions. The data we acquire will help facilitate the design of asymmetric vesicles that mimic the lipid compositions found in EVs, and shed light on the suitability of various formulation methods for different membrane compositions. This will help bridge the gap between synthetic and biological vesicles, allowing us to evaluate the role lipid composition plays in vesicle structure, fusion mechanisms and membrane stiffness.

title: Possible quantum spin liquid state in disorder-induced spin-1/2 frustrated 3D pseudocubic Ba3CuTa2O9

description: A polycrystalline sample (about 2 gram) of the title compound Ba3CuTa2O9 was prepared by the conventional solid-state reaction method. Rietveld refinement of the XRD data at T = 300 K confirms that the material is in a single phase with P4/mmm (No. 123) space group. Curie-Weiss fitting of magnetic susceptibility data indicates strong antiferromagnetic coupling (AFM CW temperature - 24 K) among the Cu2+ (S = 1/2) moments arranged in a 3D pseudocubic framework. Our susceptibility (down to 1.8 K) and specific heat (down to 690 mK) depict no evidence of long-range magnetic ordering. These measurements indicate that Ba3CuTa2O9 might host a quantum spin-liquid (QSL) state. Further, the data collapsing behavior of field-dependent magnetization at several temperatures and temperature-dependent susceptibility at several fields with appropriate scaling exponents suggests the possible existence of a random spin-singlet (RSS) state on top of a QSL state. Thus, it is essential to perform the muSR experiments to explore the putative QSL behavior in the well-characterized polycrystalline sample of Ba3CuTa2O9.

title: Spin excitations in paramagnetic MnO

description: Manganese(II) oxide, MnO, is a well-studied and well understood Anti-ferromagnet (AFM) in its low-temperature phase (&lt;118 K), but the full magnetic character of its low-temperature paramagnetic regime (118 &lt; T &lt; 600 K) remains a mystery. Triangular motifs in the face-centered cubic lattice create geometrical frustration, driving strong spin correlations to persist in the paramagnetic regime. We have recently demonstrated how the combination of this geometrical frustration and magnetoelastic coupling creates local AFM magnetic domains well within the paramagnetic phase. Any magnetically ordered domain is expected to support magnetic excitations, and indeed, these were previously detected in paramagnetic MnO. However, it is unclear to what extent spin-wave theory remains valid under these circumstances and whether the magnetic wave character will agree with our local domain picture. To test whether magnetoelastic coupling can drive local lattice relaxation within the paramagnetic regime and elucidate the nature of its magnetic excitations, we propose to carry out a modern set of inelastic neutron scattering measurements. Comparing the results with Monte-Carlo simulations and supercell lattice dynamics will allow us to determine the excitation spectrum for paramagnetic MnO, visualise the spin excitations within a local domain description and interpret the findings in the framework of spin-phonon interactions.
