title: Magnetic structure determination of novel monoclinic Kondo lattice YbPt5B2

description: In course of Yb-Pt-B phase diagram studies, novel YbPt5B2 was detected, which crystallises in a monoclinic crystal structure (space group C2/m) with its own YbPt5B2-type. Bulk property measurements reveal two magnetic phase transitions at T_mag1 ~ 8 K and T_mag2 ~ 4 K. For temperatures below T_mag2, increasing magnetic fields cause two successive field induced phase transitions below 3 T. In order to gain insight into the complicated magnetic structure and the respective temperature and field-dependent phase transitions, microscopic insights by neutron studies are indispensable. Magnetic order (magnitude and arrangements of the Yb magnetic moments) is expected to be a result of a complicated overlay of RKKY interaction, Kondo and crystalline electric field effects. We therefore propose neutron diffraction measurements on YbPt5B2 using the WISH diffractometer.

title: Long Range Structure and Zwitterion-Ion Interactions in Osmolyte Solutions

description: Cytosol composition not only dictates the osmotic balance of cells with their surroundings, but also determines the the range and nature of inter-protein interactions within the cell. While the role of salt in destabilising proteins is well known, the role that zwitterionic osmolytes play in these interactions is less clear. Here we will study model cytosol solutions of salt-zwitterion mixtures using neutron scattering. Recently we have investigated surface forces present in salt-zwitterion mixtures at an interface, and found periodic structure and long range screening forces that depend on sample composition. This experiment will investigate the occurrence of this structure in the bulk liquid, and its dependence on salt ion species. These results will have significant impact on our understanding of the role of zwitterionic osmolytes in maintaining protein structure and function.

title: Monitoring Ionic Diffusion in C60/CoB with Temperature and Voltage

description: In our previous run we successfully measured boron diffusion in C60/CoB/C60 trilayers. The structural and magnetic PNR signal was radically different after annealing at 300 ºC, with Refl1D fits showing boron diffusion both in the metal and into the molecular layer. We also completed a time-resolved PNR measurement monitoring changes at 300 ºC over 10 hours in a single Q window (up to 0.075 Å-1). Here, we will continue this research by studying ionic diffusion at higher temperature up to 350 ºC. We will also do time-resolved measurements up to 0.075 Å-1 at 260 ºCand 280 ºC to better monitor the ionic diffusion during 1 to 12 h. Finally, we will explore the effects of an electrical bias and the potential application of ionic diffusion in devices. We will attempt the electrical diffusion at 200 ºC in back-gated C60/CoB/C60 trilayers on a doped p-Silicon/SiO2substrate.

title: Impact of Li and mechanics on polymer dynamics in perfluoropolyether based polymers

description: Lithium metal based batteries are next-generation energy storage devices. A major challenge to industrial application of these batteries is uneven Li deposition on anode which results in dendritic growth and poor coulombic efficiency (CE). We recently reported that perfluoropolyether polymer networks with evenly spaced H-bonding sites of various mechanical strengths are useful as coatings on Li anode surface and batteries prepared with coated polymers with a weaker mechanical strength (i.e. better flowability) exhibit higher CE. We now plan to probe the polymer dynamics using QENS experiment correlate that with the measured viscosity, mechanics and ionic conductivity at room temperature. We believe that this will help us to understand the charge transport mechanism in this new material.

title: Natural care products: deposition studies of sustainable polymers and surfactant mixtures

description: The aim is to reveal the properties of coacervate complexes of oppositely charged natural surfactants (medium-chain fatty acid salts) and biobased cationic polysaccharides deposited on surfaces. This is needed to develop formulated products with more sustainable ingredients. Neutron reflectometry measurements on polymer-surfactant mixtures upon dilution at various SLD contrasts are expected to provide detailed information on the layering of the components (polymers and surfactants) on the model surface, in terms of the position they occupy, the thickness of each layer, how layers interpenetrate each other and their density profile within the film along the distance from the surface. A pre-characterisation (visual inspection, DLS, SAXS and ellipsometry) has shown the formation of coacervates that deposit on a silica surface, occurring when the composition approaches the surfactant CMC.

title: Enhanced magnon transport through an amorphous magnetic insulator

description: Magnonics research is focused on the transport of spin information via spin-wave, or magnon, excitations. Due to its exceptionally low damping, the magnetic insulator Yttrium Iron Garnet (YIG) is considered the most prominent material in this field. New research has been stimulated by a report of long (µm) magnon diffusion lengths in amorphous YIG (a-YIG) where there is no long range magnetic order. Similar experiments have failed to reproduce the results and spin-pumping data provides a much lower (3.6nm) spin diffusion length. We have recently measured a 28nm spin diffusion length in a-YIG (28nm) and hypothesise that samples of a-YIG may differ depending on growth conditions. In this proposal we will use polarized neutron reflectometry to investigate a-YIG in order to see if deviations away from the expected M = 0 emu/cc can explain the longer spin diffusion length in our samples.

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: Agitation-induced growth of uniform anthracene nanotubes

description: We propose a time-resolved SANS experiment to investigate the nanotubes formed by anthracene derivatives in methylcyclohexane. These systems show unique behaviour as without perturbation they slowly form amorphous aggregates, but upon perturbation they follow a far more ordered self-assembly process to yield highly ordered and uniform nanotubes. We aim to observe both self-assembly pathways via SANS to gain some insight into this unusual behaviour and the resulting self-assembly mechanism. SANS2D is essential for this experiment due to the high flux and signal-noise ratio required to study these relatively dilute systems (~0.1 vol%). The large Q-range from the overlapping detectors will allow simultaneous monitoring of morphological changes at low Q and the potential emergence of Bragg peaks at mid-high Q arising from regular spacings within the tubes.

title: Study of the low temperature magnetic ground state in the anion-disordered oxynitride pyrochlore Yb2Ta2O5N2

description: The study of geometric magnetic frustration in solid state materials has led to the discovery of exotic magnetic ground states. Some frustrated 3D lattices host quasiparticle excitations that are suitable for applications in quantum information science. One such frustrated 3D lattice is the pyrochlore lattice. The effects of cation crystal disorder in pyrochlore lattices have been studied previously and it has been found that disorder suppresses desired quantum magnetic ground states. However, a recent study exploring anion disorder in a so-called oxynitride pyrochlore has shown that anion disorder can promote desired quantum properties. Further exploration of such phenomena in oxynitrides is needed. The proposed material Yb2Ta2O5N2 provides an excellent system for this study where high-quality single crystals with anion disorder can be synthesized.

title: Effect of LL37 and LL37 lipid nanocariers on bacteriophage phi6's structure

description: During the experiment proposed, the structural effect of LL37, a antimicrobial peptide from the human immune system, on the bacteriophage phi6 (a virus that infects only bacteria) will be investigated. The effect of LL37 on the different parts of the virus will be understood by collecting scattering patterns at varying concentrations of deuterated water. Moreover, the interaction of recently designed LL37 lipid nanocarriers with phi6 will be studied, helping to understand the enhanced antiviral activity of the nanocarriers compared to the LL37 alone. Fully deuterated lipids nanocarriers will be used to study the integration of lipids from the carriers to the viral envelope. Overall, the structure-function relationship will be established allowing to understand the underlying mechanism on the viral inactivation. This knowledge will help design a future generation of antiviral compounds.

title: Structure and Evaluation of Nanodrug Hydrogel Delivery Systems for Psoriasis Treatment using Rheo-SANS

description: The experiments will evaluate and optimise a novel smart controlled release injectable liposomal hydrogel drug delivery systems from low cost precursors, Pluronic F-127 and chitosan. The matrix’s sol-gel phase transition in the body allows them to be administered as drug loaded solutions before transforming to soft gel depots at body temperature, then release the drug over a designed time. liposomes structural similarity to cells allows for enhanced drugs bioavailability and increased blood circulation time. The proposed systems are designed to regulate the release of Secukinumab® for the treatment of plaque Psoriasis, aiming to reduce cost, dosing frequency and enhance patients’ compliance. The requested beamtime will allow us to investigate the effects of combined shear and extensional flow as experienced during real bodily administration on the system's morphology and stability.

title: Interactions between a quadruply-charged X-shaped peptide and bacterial Lipopolysaccharides (LPS) micelles: Complexation or penetration

description: Lipopolysaccharides (LPS) is the main component (~75%) of the Gram-negative bacteria outer membrane which can trigger lethal septic shocks when released into a host’s bloodstream. Oligoglycine tetramer is a cationic four-armed X-shaped synthetic peptide with quadruple charges. The anionic phosphorylated and carboxylated headgroup can be targeted by the X-peptides, conjectured to reduce bacterial virulence via shielding its viral adhesion receptor, as well as affecting the elastic properties and structural integrity of bacterial membranes. We propose a SANS study of the interactions of LPS micelles mediated by the X-peptides, varying the concentration, solution pH and temperature, as well as the LPS architecture. The unprecedented results will underpin understanding of the efficacy of the X-peptide as an antimicrobial peptide in compromising the bacteria membrane structure.
