title: Water structure in radiation-grafted anionic exchange membrane for fuel cell applications, and its role in charge transport

description: Over the past few decades, fuel cell research has grown exponentially with the continued development of new materials and systems for automotive and stationary applications. Most interest has focused on polymer electrolyte (both proton -PEM- and anion -AEM- exchange membranes) membrane fuel cells because of their power densities, lower cost, and wider applications. Albeit intensive efforts have been made to develop and improve AEMs membranes, they still display poor ionic conductivity. This is also because, to date, very little is known on the relation between OH- transport and water dynamics. In this proposal, we want to investigate the role of water structured around the counterion in ad hoc synthesized AEM membrane to unravel the transport basic mechanisms and with a view to advancing towards help designing advanced higher performance AEMs.

title: Establishing the chiral helimagnetic state in single crystals of Cr1/3TaS2

description: Noncentrosymmetric systems lack a centre of inversion, which can lead to interesting magnetic phenomena. Cr1/3NbS2, a chiral helimagnet, has been shown to host a chiral soliton lattice, i.e., 360 degree domain walls separated by regions of ferromagnetism, in an external field. Its sister compound, Cr1/3TaS2, has now been found to host a chiral soliton lattice as well, but a chiral helimagnetic state has yet to be confirmed with neutron diffraction. Preliminary neutron diffraction measurements on polycrystalline Cr1/3TaS2 indicate an incommensurate phase is present, which could be the fingerprint of chiral ordering. We propose to use single crystal diffraction measurements of Cr1/3TaS2, as well as the high resolution possible for WISH time of flight measurements, to establish its long range ordering and establish its magnetic propagation vector.

title: Study of possible quantum Dirac string in Nd2Zr2O7 in the (001) fields

description: Magnetic pyrochlore compounds display various fascinating physical phenomena due to geometrical frustration on the network of corner-sharing tetrahedra in the crystal structure. The classical spin ice state with macroscopic degeneracy and monopole-like excitations connected by Dirac strings are probably the most striking which was observed in (Ho/Dy)2Ti2O7. Classical spin ice (CSI) can be melted by quantum fluctuations introduced by terms transverse to the Ising axes in the spin Hamiltonian [3]. A magnetic field along the (001) direction polarized the spin ice state and aligns the Dirac string along the field direction. Here we propose to measure the excitations of the polarized quantum spin ice state in Nd2Zr2O7 in (001) field which could be propagating quantum Dirac strings.

title: A structural study of amino acid salts to elucidate their role in carbon capture

description: A current major challenge is the large released of carbon dioxide (CO2) into the atmosphere leading to climate change. There is considerable interest in amino acid salts as an alternative solvent for the absorption of CO2 into a solvent such that carbon can be stored, and later released for useage. We aim to achieve a molecular level structural understanding to the superior performance of potassium amino acid salts compared with sodium amino acid salts, and aid in the intelligent design of future CO2 capture solvents. This will also serve as a crucial foundation to a host of future studies of carbon capture solvents, is of fundamental importance to the entire carbon capture solvent community and is particularly timely in the context of the Net Zero Strategy proposed by the UK government.

title: Reciprocal Space Tomography of the Tilted Low temperature Skyrmion State in Cu2OSeO3

description: Skyrmions are magnetic, vortex-like whirls of magnetisation which have received great theoretical and experimental attention due to their interesting physics and potential to be used in spintronic devices. A low temperature skyrmion (LTS) phase (&lt;20 K) in Cu2OSeO3 was found to form under the application of a magnetic field parallel with a [100] direction. We wish to investigate the effect of tilting the magnetic field on the LTS, and investigate their formation and stability. We intend to do this by creating novel, state-of-the-art reciprocal space tomograms of 3D reciprocal space to completely characterise the tilted LTS, allowing us to disentangle the anisotropic interactions required for their formation.

title: Influence of polarisation analysis on buffer subtraction in biology

description: Protein dynamics play a vital role in biology. Quasi elastic neutron scattering is an ideal method to access these, data analysis is performed based on the assumption that the scattering spectrum is incoherent. To observe the full range of dynamical changes the proteins need to be observed in solution. This solution is usually a fully deuterated buffer, while the protein remains deuterated. It is generally assumed that while the buffer leads to a coherent contribution, which can be taken into account during data analysis by subtracting the buffer contribution from the sample spectrum. Polarised QENS experiments on LET allow for the coherent and incoherent contributions to be separated. By comparing the results from the polarised QENS experiment and the standard analysis method from unpolarised QENS it will be possible to experimentally check the current approach to data analysis.

title: Neutron Diffraction Studies of Metal-Organic Frameworks for Hydrocarbon Separations

description: Separation of light hydrocarbons is a highly challenging and energy-intensive industrial process. We seek to develop highly robust MOF materials as efficient sorbents for hydrocarbon separation and request 4 days on WISH to study the preferred binding sites and locations of adsorbed gas (CO2/C2D2/C2D4/C2D6/C3D6/C3D8) within a top-performing MOF, CALF-20. This proposed study will investigate the precise locations of light hydrocarbon molecules and CO2, defining the preferred orientation of molecules with respect to the binding sites in CALF-20. CALF-20 exhibits exceptionally high separation property for mixtures of CO2/C2H4, CO2/C2H2, C2H2/C2H4/C2H6 and C3H6/C3H8 at ambient conditions with fully repeatable cycles, suggesting the presence of specific guest-host interaction. The proposed study aims to reveal the nature of these interactions through structural insights into the pore .

title: Revealing mechanistic processes in Na-NiCl2 batteries

description: With the move to electrify energy distribution in worldwide and with significant interest worldwide in development of "beyond lithium" technologies, there is increasing focus on alternative battery chemistries. One such chemistry is the Na-NiCl2 system with a Nasicon solid electrolyte. In this technology, developed for larger scale energy storage solutions, the cells operate at elevated temperatures, and are supported on a metallic substrate. This morphology presents challenges in undertaking analysis of the key electrochemical processes occurring at, or near, to the electrode/electrolyte interfaces. Using Bragg edge tomography we will be able to reveal key mechanistic processes from a series of pristine, charged and discharged cells that will be correlated with the electrochemical data obtained ex-situ.

title: Neutron scattering study on the magnetic and lattice structures of EuCo2Al9

description: Triangular-lattice antiferromagnet (TLAF) exhibits a rich variety of physics. A symbolic quantum effect predicted for TLAF is that magnetization is quantized at one-third of the saturation magnetization Ms in magnetic fields, which suggested the magnetic structure as a up-up-down phase. A number of theoretical approaches for explaining the quantum mechanism of the Ms/3 plateau have been proposed. In contrast, the progress of experimental research is relatively slow due to the limitation of material preparation. Recently, TLAF EuCo2Al9 single crystal has been synthesized and exhibit exotic physical phenomena, such as the existing of two consecutive magnetic transitions and fractional magnetization platform. We propose to study the structure information in EuCo2Al9, which will help us better understand the physical mechanism behind interesting macroscopic phenomenon.

title: Lipid bilayer structure in coexisting regions of low and high curvature

description: Withholding high membrane curvature is a very important feature in biological membranes. Continuous and dynamic changes in membrane composition take place that give rise to regions of very high curvature in processes such as endocytosis and cell division. In endocytosis, the necks that are produce have radii down to 20 nm. Such high curvature can be sustained thanks to an interplay between lipid-protein, where lipids of intrinsic high curvature and specific proteins are recruited by such regions of high curvature. Fluorescence microscopy has been the technique of choice to study curvature induced phase separation and molecular binding. There is little to none structural information on bio-membranes in high curved regions with such low curvature. Here, we will study coexisting flat and curved membranes composed of lipid mixtures with high and low intrinsic curvature by Neutron reflection.

title: Field-tunable magnetic order and excitations in quantum spin liquid candidate NaYbSe2

description: NaYbCh2 (Ch = O, S, Se) does not form magnetic order down to 50mK in the presence of considerably strong antiferromagnetic interactions, and is suggested to exhibit a highly fluctuating QSL ground state. By comparing the structure of our magnetic excitation spectra with the theoretical expectation from the spinon continuum, we conclude that the ground state of NaYbSe2 is a QSL with a spinon Fermi surface. Moreover, our recent results of NaYbSe2 reveal a dispersive magnetic excitation continuum with clear upper and lower excitation edges under magnetic fields (up to 4 T). To further complete the measurements at a higher magnetic field region (up to 9 T), determine the accurate magnetic interactions, and corroborate the spinon Fermi surface picture, we propose to measure momentum-dependent low energy magnetic excitations under magnetic fields.
