title: Structure of Magnetosomes from Magnetospirillum gryphiswaldense

description: Aim of this proposal is to study the structure of magnetosomes, which are chains of iron oxide (Fe3O4) nanoparticles that we are able to extract and purify from Magnetospirillum gryphiswaldense bacteria. Magnetosomes are of significant interest as tools for delivery drugs to a targeted area because of their small size, ferromagnetic properties and presence of membrane proteins embedded in the lipid bilayer that covers the surface of the iron oxide core. Structural information regarding core and layer dimensions as well as layer composition and number of magnetosome units per chain will be obtained with contrast variation SANS experiments that we plan to perform on samples obtained by bacteria that have been grown under a wide range of controlled conditions.

title: Distinguishability between ancient and modern leaded tin bronzes by the composition of their lead inclusions using neutron diffraction: prel

description: The composition of lead inclusions in modern and ancient leaded tin bronzes was studied by X-ray diffraction and X-ray fluorescence. It was found that the lattice parameter of lead inclusions in all bronzes was smaller than the lattice parameter of pure lead. This determination indicates that lead inclusions in bronzes are nothing else but Pb-Sn solid solutions.Tin concentration in lead inclusions in modern bronzes was not less than 3%, whereas for ancient bronzes was as low as 1%. This difference enables a distinction between ancient bronze artefacts and modern products including the most sophisticated counterfeits. X-ray diffraction is not always suitable since preparation of the surface is necessary. We propose to use ND as an alternative method for the measurement of the lattice parameter of lead inclusions with precision about 0.001 Å.

title: Determination of the interaction parameter between vinyl alcohol and vinyl acetate in PVAc

description: Polyvinylalcohol, PVA, is an increasingly important industrial material used for water-soluble unit dose applications. Vinyl alcohol cannot be directly polymerised; therefore PVA is prepared by the hydrolysis of polymerised vinyl acetate, PVAc. For most applications the PVA is incompletely hydrolysed and the residual acetate groups while not inherently hydrophilic help to suppress crystallisation and render the copolymer more soluble. Remarkably, we can find no direct measure of the compatibility of PVAc and PVA in the literature, but this is important to understand in order to predict the solubility and interdiffusion behaviour of the material. We propose to use SANS to study well-defined blends of deuterium-labelled P-dVAc with PVAc of the same degree of polymerisation but somewhat different degrees of hydrolysis. These experiments will provide detail structural analysis of PVAc in the melt state as well as the interaction parameter between VA and VAc groups.

title: Characterisation of a Multi-layer Boron-coated GEM detector for transmission measurements

description: Future spallation sources require new detectors to performe experiments at very high count rate. A new GEM detector optimised to detect thermal and epithermal neutron has been developed at Milano-Bicocca University and ITSP-CNR laboratories. The detector has been equipped with a series of GEM foils coverd on both side with a B4C layer (BGEM) and with 6 BGEM foils a detection efficiency of 20% may be reached. A series of relevant standard samples will be investigated in order to verify the detector features in realistic conditions. We expect the use of this detecotr in transmission geometry may improve the quality of cross section data in thermal and epithermal neutron range.

title: The structural effect of salt concentration and freezing rate on icy grains relevant to moons and their ejecta.

description: Icy moons are leading candidates for habitability in our Solar System. Plumes exist on some of these ocean-bearing moons, where ocean material is ejected out into space as ice grains. These ice grains currently provide our best probe of potentially habitable oceans beyond Earth; however, the formation and structure of these icy brine grains are not understood. These grains are known to contain vein structures of salt networks within an ice matrix. We intend to use the unique capabilities of NIMROD to characterise vein materials within icy moon-relevant ice grains, and the degree to which they are segregated from icy matrix material. This will lead to better understanding of the properties of icy moon-relevant ice grains and the conditions under which vein material can form within them.

title: Triple-q state vs zigzag state: magnetic ground state determination of Na2Co2TeO6

description: Na2Co2TeO6 was theoretically proposed as a candidate material for the Kitaev quantum spin liquid (KQSL) and was found experimentally to exhibit resemblances to previous Kitaev materials. However, it develops antiferromagnetic order at low temperature and magnetic ground state remains controversial. To better understand magnetic interactions and tunability towards KQSL, we propose a diffraction experiment to distinguish between two ambiguous states (triple-q and zigzag states). As diffraction patterns of proposed ground states are identical, diffraction experiment with uniaxial strain is required using distinct responses to the strain expected for zigzag and triple-q states. In the case of successful realization of our experimental program, the puzzle of magnetic ground state of Na2 Co2TeO6 will be resolved, establishing a solid foundation for further understanding of the magnetic interactions in this material and its tunability towards KQSL.

title: Understanding microscopic properties and drug diffusion kinetics in a long-acting peptide hydrogel drug delivery implant for combined contraception and HIV prevention.

description: There is a major need for a single effective platform to delivery both HIV/AIDS and contraceptive drugs over a prolonged period e.g. 28 days We are developing a hydrogel implant, composed of biologically stable peptide-like molecules termed peptoid-D-peptides, that form gels in response to enzymes present within the skin. Patients struggle to adhere to complex regimens of these medicines, which require a cocktail of drugs to be taken several times daily. Our therapy removes this need, improving adherence to medication and reducing mother to foetal HIV transmission. This project will explore the role of gel fibre structure and entangled gel fibre networks on both i) mechanical (gel formation, rheology, gel strength) and ii) drug release properties (drug cleavage from peptoid-D-peptide, drug diffusion). Small angle neutron scattering will be used to probe the properties of gel fibres in the presence of multiple HIV/AIDS and contraceptive drugs. This will provide SANS data that will be valuable in optimising the peptoid-D-peptide’s chemical structure and formulation parameters for 28 day combined delivery of HIV/AIDs and contraceptive drugs within one injectable product.

title: Probing the dynamics of lignin derived monomers to parametrise molecular dynamics simulations

description: Cresols, anisole and guaiacol are small aromatics that are involved in numerous industrial processes and are significant intermediates in the transformation of lignin from biomass for producing fuels and value-added chemicals. These molecules contain hydroxyl and methoxyl functionalities common to lignin and have different molecular shapes, which will likely impact their mobility. Bulk liquid mobility is often a limiting step in extraction, separation and catalysed conversion processes. We propose to use QENS to study the diffusion and local motions of the o- and m-cresol isomers (having already studied p-cresol) from 340 - 390 K, and given enough time we also wish to study anisole and guaiacol dynamics. This study will help us analyse the accuracy of molecular dynamics (MD) simulations applying current OPLS force-fields which have already been performed. QENS can be used as an additional metric for parametrising classical computational models that were manufactured to replicate thermodynamic properties only. Accurately simulating intermolecular interactions to replicate the diffusion mechanisms of liquids precedes mobility studies upon their confinement in catalysts for their conversion.

title: How does hydrophilicity change affect adsorption of non-ionic surfactant and monoclonal antibody on PDMS surface?

description: Coating of a layer of polydimethylsiloxane (PDMS) film on the surface of glass or polymeric syringes is widely adopted as the common approach to reduce interfacial friction and avoid syringe jamming. However, the PDMS surface has very different chemical nature from glass or solid plastic substrate and will elicit adsorption of antibody therapeutics, causing structural instability and aggregation. Nonionic surfactants such as Tween 80 (PS80) are widely used to control antibody adsorption, but their exact impact is little explored because many techniques cannot distinguish protein from surfactant at the interface. Following our recent studies of adsorption of PS80 surfactants and antibody onto the PDMS film coated silicon substrate by spectroscopic ellipsometry, we propose a set of neutron reflection studies to determine interfacial structural features that underline how PS80 with different numbers of EO unit can co-adsorb with COE-3 at the PDMS/solution interface.
