title: Study on the dynamics of hydride ion conduction in new oxyhydrides

description: Hydride ion conductors are the new frontier materials in the research field of solid-state ionics. Indeed, hydride ion conduction is particularly attractive for electrochemical devices such as fuel cells and batteries, because hydride ions have suitable ionic radii as mobile ions and strong reducing properties. Recently, our group reported for the first time pure hydride ion conductivity in new oxyhydrides. We propose therefore to study the elementary mechanism of hydride ion conduction in this promising class of materials, using quasi-elastic neutron scattering.

title: Unusual higher order incommensurate components in the magnetic structure  of  TmCu

description: This proposal forms a very specific part of our project to investigate complex magnetic structures in rare earth intermetallics. In extensive bulk measurements on high purity TmCu single crystals, we have discovered a unusually large and sign changing contribution to the Hall effect. This signal appears to be linked to distinct pockets in the magnetic phase diagram. In the context of the topological Hall effect, this supports our case of reinterpreting magnetic multi-k structures as real space topological objects, sometimes referred to as hedgehogs or skyrmions. With this proposal, we follow up on our previous neutron measurements at the ILL and FRM2, where we observed unusual higher-order modulations of the magnetic structure, associated with certain phases. WISH at ISIS is uniquely suited to establish a clear overview and understanding of this magnetic ordering process in TmCu.

title: Lithium conduction in Thermotropic Ionic Liquid Crystalline Polymers investigated by QENS

description: We have recently developed a new class of single-ion conducting Thermotropic Ionic Liquid Crystalline Polymers, TILCPs, for application as lithium battery electrolytes. Within the herein proposed study, we will systematically investigate the ion dynamics in this new class of polymer electrolytes as a function of temperature using quasi-elastic neutron scattering, QENS, on IRIS. This study will allow an in-depth characterization of the diffusion mechanism as function of i) the ionic species (Li+, H+), ii) the macromolecular architecture (3 types of TILCPs will be studied, each with a H- & D-labeled polymer backbone), and iii) the nanostructure (dynamically self-assembled mesophases). This comprehensive study targets to establish the interplay between ion transport and liquid crystal structures, thus, enabling the identification and design of highly conductive electrolytes.

title: Investigating magneto-superconductivity of CeO0.5F0.5BiS2 and Ce0.5Sr0.5FBiS2

description: In this proposal we plan to investigate the anomalous magnetism of Ce in recently discovered CeO0.5F0.5BiS2 and Sr0.5Ce0.5FBiS2 magneto-superconductors. The proposed compounds show superconductivity at below 3.5K and the ordering of Ce moments at below around 8 K. The BiS2 based superconductors, which are similar in structure to the Fe Pnictides are attracting huge attention of the condensed matter physics community. The studies related to the order parameter symmetry at ambient pressure may help in not only understanding the superconducting state but the competing ferromagnetism arising from Ce moments as well.  We therefore propose to carry out zero-field muSR study on there two compounds using EMU.

title: Valence bond solid in the charge ordered state of Rb4O6

description: Open p-shell anionic mixed-valence compounds have been recently proposed as intriguing model systems for disentangling the complex interplay of charge, lattice, orbital, and spin degrees of freedom in Verwey-type charge ordering processes. Our preliminary electron paramagnetic resonance experiments on Rb4O6 have shown a zero-field spin gap of about 450 GHz, which can be closed with a magnetic field of 14.5 T. The results are consistent with formation of O2- (S = 1/2) dimers with a singlet ground state and indicate the presence of additional inter-dimer isotropic and intra-dimer Dzyaloshinskii-Moriya interactions, thus questioning the true ground state that could either be a valence bond solid or a long-range magnetic order with reduced ordered moments. Here we propose to carry out a muSR investigation down to the lowest experimentally accessible temperatures to answer this question.

title: Technological study of Nuragic Bronze boat models (Sardinia, Italy)

description: The production of Nuragic Bronze Figurines represents a rich historical archive that provides key information not only about the iconography but also about the metal production and casting techniquesand on the development of the Mediterranean basin metallurgy [1].The period of their production is principally Early Iron Age (10th-7th century BC). The small bronze sculptures, made in lost wax, not always were cast in a single solution but, as can be inferred from a simple observation, most of the parts of the wax model were moulded separately and then joined. In the composition of bronze objects, one of the major difficulties was joining the different elements that make the form in its entireness. We propose to analyse three nuragic boat samples. The data obtained through this technique will permit to measure the phase composition and microstructural features of the metal matrix.

title: Studies of Free Radical Final States on Au nanoparticles by RF-muSR and ALC Spectroscopy

description: Small-sized metal nanoparticles (NPs) are of long standing interest to both magnetism and heterogeneous catalysis. Recent µSR studies of bare Au NPs encapsulated in mesoporous silica have explored the diamagnetic final state of a spin-polarised muon on the surface, formed by an electron-loss reaction of chemisorbed Mu on the Au NP, with final-state RF measurements (at ISIS) providing a direct method of studying this species. The focus of the present proposal is different, in this case we are planning to investigate paramagnetic final states formed on Au NPs by Mu reactivity with surface-absorbed molecules. The study will require both RF and ALC measurements, and therefore makes good use of the capabilities of the HIFI spectrometer. Measurements of both surface-adsorbed benzene and iso-butene are proposed, to study the muoniated cyclohexadienyl and t-butyl radicals respectively.

title: DNA unwinding mechanism of the archaeal helicase PabMCM

description: The process of cell division requires precise duplication of the genetic material. The separation of the two strands of DNA and the progression of the replisome are driven by replicative helicases called Mini-chromosome maintenance (MCM) proteins. MCMs unwind genomic dsDNA to expose ssDNA template during the S-phase of the cell cycle. We have recently solved the first full-length octameric structure of the Pyrococcus abyssi MCM (PabMCM) by electron microscopy and SAXS. PabMCM can be found as single or double octameric ring assemblies in absence of DNA; however, bound to dsDNA, PabMCM is found exclusively in single ring assemblies bound to the DNA substrate. We plan to continue using small angle neutron scattering to solve the structure of MCM/DNA complexes with contrast matching experiments. These experiments allow to discriminate the protein and DNA component in a full complex.

title: Origin of ultra-low thermal conductivity in Zintl-type TlInTe2: An Inelastic Neutron Scattering Study

description: Materials displaying ultralow lattice thermal conductivity (k_Lat) are crucial to realizing high performing thermoelectric materials to convert waste heat into electrical energy. Recently, we have discovered an ultralow lattice thermal conductivity (ca. 0.5 W/mK at 300 K) in Zintl-type TlInTe2 compound. First-principles DFT calculations in TlInTe2 reveals low-frequency optical modes arising from rattling Tl atoms and coupling to heat-carrying acoustic phonons through symmetry-allowed interactions. As such, we strongly believe that acousticoptic anharmonic coupling is likely to play a central role in explaining the low thermal conductivity of TlInTe2. Inelastic Neutron Scattering (INS) data as a function of temperature will enable us to extract phenomenon on an atomic scale and help us to investigate the fundamental cause for the intrinsically low k_Lat  in TlInTe2.

title: Effect of End Group on RAFT-Polymers for Lipid Nanodisc Stabilisation

description: Polymer stabilized lipid nanodiscs offer enormous potential as tools for enabling membrane protein structural studies & biophysics. Previously we studied discs formed using a poly(styrene-alt-maleic acid) (PSMA) copolymer, and variants of this material synthesised using RAFT controlled radical polymerisations.  The RAFT method results in a C12 chain on the end of the styrene tail of the polymer, from the RAFT agent that controls the polymerisation reaction. Removal of the RAFT endgroup leaves a hydrophilic cyanoisopropyl group, which can be then further functionalised. We have prepared a series of polymers where the endgroup has converted to a cyanoisopropyl group, which, based on DLS measurements, appears to destabilise polymer aggregation in solution and favour stability of larger lipid aggregates. Here we wish to ensure these polymers form discs and probe effects on disc structure.

title: Solvent and drug diffusion in supramolecular gels

description: This proposal addresses issues related to understanding drug diffusion in supramoleculargels with view at fundamental pharmacological questions for drug delivery. Preliminary data from IN6 (ILL) and LET indicate a small but systematic difference in the diffusion of the solvent withinsupramolecular gel samples compared to the diffusion in the corresponding pure solventsamples. We hypothesize that this trend is due to soft micro-confinement effects and we now propose to verify this trend by measuring a second solvent system on LET. In addition, we wish to measure new samples withthe model drug ibuprofen sodium load. The results from these experiment will directly influence the understanding of supramolecular gels as drug delivery vehicles.

title: Formulating polymer solutions to stabilise polymeric foams

description: Polyurethane foams (PUF) are commonly prepared by mixing Pluronic type copolymers and isocyanate reactive monomers in the presence of additives e.g. catalysts, blowing agents and surfactant. The physical properties of the resultant foam (cell morphology and size, capacity for water adsorption, thermal insulation etc) are strongly dependant on the surfactant blend employed in the foam formulation. Our previous work has shown that novel, stacked structures form at the interface. Here, we wish to extend the interfacial study of these interesting materials, and the role that the formulating surfactant blends play in defining the detail in this novel structure. The over-arching aim of this PhD project is to better understand the role of the surfactant in stabilizing the foam structure and its perturbation on inclusion of novel additives, both small molecule and particulate in nature.

title: Stress-assisted Martensite  Influence of martensite initiation mode on variant selection and subsequent work hardening rate

description: The aim of the present proposal is to determine the influence of the different martensite transformation regimes (either stress-assisted or strain-induced) on the proceeding work hardening rate in austenitic stainless steels. Also, the effect martensite transformation have austenite matrix and further martensite transformation will be monitored. Ultimately, the results will be used towards identifying the most favourable austenite orientations to promote martensitic transformation inducing the maximum level of work hardening.

title: Interactions between lipoprotein particles from human serum and model blood vessel surfaces - Implications on atherosclerosis development.

description: In westernised societies, atherosclerosis and its clinical consequences such as heart disease and stroke constitute the leading cause of death. Thus, the prevention or deceleration of atherogenesis is one of the most significant medical objectives since this is a matter of avoiding myocardial and cerebral infarction. Taken together, current knowledge recognises a whole range of indicators associated with atherosclerosis, including the relative concentration of various lipoprotein particles. Here, we propose to study the structure of lipoprotein particles at the surface of various components of the vessel wall. For this we will start with the well characterised heparan sulfate - LDL/HLD system to unravel the fate of the lipoprotein particle components in the heparan sulfate coated silica surfaces by means of neutron reflection. We start with lipoprotein particles from human blood.

title: Determination of total cross sections and effective temperatures of atoms in normal and deuterated alcohols

description: The alcohols are compounds widely used in many industrial applications. Many of the structural and dynamical properties of these compounds  are due to the existence of intermolecular hydrogen bonds.  It is of general interest the study of their dynamic and structural properties. Our group follows a research program in the study of the structure of alcohols by means of different neutron techniques, and recently we studied a set of normal and deuterated alcohols with polarized neutrons at spectrometer D3 (ILL, France), to accurately separate the observed coherent and incoherent components of the spectra, to allow the determination of the structures. The process requires a refined data processing procedure that involves the knowledge of the total cross sections and the effective temperatures. VESUVIO is unique in its class allowing to determine such magnitudes in a single experiment.

title: Strain effects in filled rubber nanocomposites

description: The overall aim of this project is to understand the origins of energy dissipation mechanisms in filled rubbers. These effects are responsible for much of the carbon footprint associated with road transport today. We have so far successfully used QENS and SANS to address the dynamics and structure of model silica filled polybutadiene nanocomposites. QENS shows little impact of crosslinking on dynamics, but a significant reduction in polymer mobility when silica nanoparticles are added.  We now turn our attention to the dynamics of these systems whilst under an imposed strain, which mimics the process responsible for rolling resistance in tyres. QENS will be carried out on a series of filled rubber samples in which the filler and loading and applied strain are systematically varied.

title: Effects of confinement on polymeric surfactants

description: Polymeric stabilisers are often used in the preparation of emulsions and dispersions of particles. The purpose of this additive is to help keep the mixture stable so that it can be prepared, transported, stored and eventually used. The polymer must prevent collisions between emulsion droplets or nanoparticles; however, the actual structures of the polymer in the region between the two colliding surfaces are completely unknown. We have recently shown that the inter-surface structures of polymer brushes is not well described by existing osmotic pressure models and that raises the question of whether the traditional picture of adsorbed polymeric stabilisers is correct. We aim to probe adsorbed polymeric layers to determine how easily they collapse and measure the structures involved in the stabilisation of the surfaces.
