title: Probing the origin of the superconducting spin-valve effect

description: Inter-layer exchange coupling through charge and/or spin carriers is the key control mechanism for the field of nano-magnetism and is often coupled to other spintronic effects, such as giant-magnetoresistance (GMR) and spin transfer torques. Very recently, Zhu et al. reported a new class of inter-layer exchange coupling, i.e. the RKKY coupling through a superconducting spin-valve structure. They observed a GMR-like response with an infinite MR ratio because of the zero resistance in the superconducting state. One of the conclusions presented in the paper is: 'the behaviour reported here cannot be explained on the basis of any conventional exchange coupling'. We intend to combine PNR studies above and below the superconducting transition with spin-transport studies across the superconducting interfaces in order to investigate the mechanism behind the coupling.

title: Dynamic studies on the Li2B12H12 formation for 2LiBH4+MgH2/2LiH+MgB2 destabilized hydride system

description: The use of fossil fuels as an energy supply becomes increasingly problematic from the point of view of both environmental emissions and energy sustainability. As an alternative, hydrogen is widely regarded as a key element for a potential energy solution. However, hydrogen storage is one of the main constraint. Solid state hydrogen storage is a potential alternative to address this problem.  Tetrahydroborates are interesting materials for hydrogen storage because of their high gravimetric and volumetric hydrogen capacity, e.g. LiBH4: 18.3 wt. % H2 and 122.5 kg/m3 H2. However, those tetrahydroborates stable at room temperature release hydrogen under thermal input only at high temperatures and present extremely harsh re-hydrogenation conditions. Neutron spectroscopy is a powerful tool to improve this promising hydride materials.

title: Impact of Stereochemistry and Diamine Structure on Absorption of Constructed Chiral Gemini-like Surfactants at the Air-Water Interface

description: Chiral gemini surfactants containing stereogenic centers and two amphiphilic moieties, not only maintain the chiral properties, but also exhibit stronger aggregation properties, a range of different aggregation behaviors and aggregate morphologies. Difficulties in synthesis and lack of powerful analysis techniques have limited our knowledge of their self-assembly at air-water interface. This proposal is about emulating their properties through the formation of chiral gemini-like surfactants by the interaction of a single alkyl chain surfactant with bola-type connecting molecules, chiral diamines. We request here neutron reflection beam time to obtain the essential structural characterization of such mixtures, to investigate the role of stereochemistry on their absorption at the air-water interface.

title: To investigate the orbital glass physics coexistence with re-entrant structural transition in BiCuMn6O12 using inelastic neutron scattering

description: The new solid solution in the quadrupole perovskite family, BiCuMn6O12 attracts considerable attention by producing a mixture of Mn3+ and Mn4+ which introduce charge degree of freedom. No evidence of long-range magnetic order was noticed down to 2 K in neutron diffraction study except the presence of short range ferromagnetic correlations. It shows re-entrant structural transition on cooling which is quite new in the family of quadrupole perovskites. But the underlying physics behind this peculiar behaviour is still to be explored and spin dynamics need to be investigated in detail. We propose here to perform inelastic neutron scattering experiment on the polycrystalline sample of BiCuMn6O12 to investigate the spin wave excitations which will deliver adequate information on spin-gap, crystal field anomalies and provide a microscopic picture of magnetic interactions pathways.

title: The interaction of benz[b]anthracene, triphenylene and coronene with Raney Ni

description: Deactivation of catalysts often occurs through coking, where extensive carbon networks cover the catalyst surface. Simulation and measurement of polycyclic aromatic compounds will act as a model of the formation of coke on these materials. Coke is an amorphous carbon, which can resemble carbon black, which is also widely used as catalyst support. The primary structure of carbon blacks has basic structural units that may be thought of as complex PAHs with organic functional groups. We have performed some theoretical and experimental studies to understand the geometrical and electronic properties of these BSUs but more detailed studies are required to model the exact nature of these systems and their behavior, which will lead to designing of novel catalyst and better catalyst supports. We plan to attain this by combining INS experiments with the state-of-the-art DFT calculations.

title: Deformation Studies of Mg-PSZ under Compressive and Tensile Loading

description: Zirconia is a brittle ceramic whose usefulness is negated by phase transformations which are accompanied by strains and the consequent stresses lead to cracking. The addition of MgO stabilises the high temperature phases. Transformation is triggered by an applied stress, so that crack tips are closed by the dilatational strains. This transformation toughening makes for a useful engineering material. There are two, little-understood features of the material. First, the martensitic transformation in Mg-PSZ is time-dependent, causing creep under a constant stress. Second, when the applied stress is removed, the creep reverses. These phenomena occur under both tensile and compressive stresses, but at very different magnitudes.  A model has been proposed that explains some aspects of this behaviour and this project aims to test it and to further understand these features.

title: Investigating the Diffusion Properties of Mixed Anion Perovskites

description: Since 2009, perovskite solar cells (PSCs) have become a topic of immense interest in the research community, while performances of PSCs are in a position to challenge the current market standards they are still held back by several major flaws. One of these problems is that many PSCs show strong hysteresis when measured. This means that a much higher efficiency is measured when scanning from open circuit to short circuit. It is theorised that movement of ions in the material is responsible for this. Another problem is stability of the materials. It is known that swapping the standard iodide anion for small amounts of bromide can enhance stability with no performance loss, what is less understood is how this affects the underlying materials properties. The objective of this experiment is to investigate how the addition of bromide affects the ion movement intrinsic to perovskite materials.

title: Interactions of polyfluorinated substances with a phospholipid bilayer

description: Poly- and perfluoroalkyl substances (PFASs) have been used in various industrial applications and consumer products, but have received increasing global concern due to their persistence, bioaccumulation and adverse effects on living organisms. Some of these compounds are now banned and more are expected to follow. There is, however, a lack of fundamental understanding of their interactions with cell membranes or the dangerous concentration limits.  We have studied the interaction of three groups of perfluoroalkyl substances (i.e. carboxylic, sulfonic and sulfonamide acids) with a phospholipid bilayer, DMPC.  The results showed that they interact strongly with the lipids and are incorporated into the bilayers, displacing the lipids. The new experiment aims to explore how polyfluorinated substances, which are used as alternatives to perfluoroalkyl substances, interact with DMPC.

title: Lattice and proton vibrational dynamics in Sc-doped BaTiO3 proton conductors

description: Proton conducting BaTi1-xScxO3Hx (BTS) perovskites are promising materials for proton conducting fuel cells in the intermediate temperature regime (200-600 °C). Compared to BaZrO3-based materials, BTS undergo a phase transition between the cubic perovskite structure at high doping level, and a 6H hexagonal perovskite phase a low doping level, associated with a drop in proton conductivity. In order to link the macroscopic conductivity behavior to the proton diffusion mechanisms, we aim to characterize the lattice and proton vibrational dynamics and, subsequently, the proton local environments for both the hexagonal and cubic phases. The results will be valuable not only to understand the change in behavior with the phase transition, but in a larger view, will provide insights on the effects of acceptor-doping in proton conducting perovskites over a large composition series.

title: Magnetic study of the new skyrmion-carrying material CoZnMn

description: Nanoscale magnetic skyrmions are swirl-like magnetisation entities that satisfy topological quantisation conditions. They can therefore not be easily unwound into another magnetisation state, giving them a unique robustness. The ultralow energy threshold for their collective motion makes skyrmions promising candidates for future spintronics applications. Here, we propose to study the novel room-temperature skyrmion material CoZnMn in thin film form. CoZnMn has a non-centrosymmetric crystal structure, similar to the P213-type helimagnets, with largely unexplored magnetic properties for thin films.

title: Rapid microfluidic phase mapping of SDS:water:butanol

description: Sodium dodecyl sulfate (SDS) is an anionic surfactant, extensively employed in cosmetics and personal care, as well as in pharmaceuticals and food products. Surfactants are generally used in multi-component aqueous formulations, containing co-surfactants, co-solvents and salts, as well as polymers or colloids. Establishing multi-component phase diagrams is complex and time-consuming, given the large parameter space which, in addition to composition, can involve temperature, pressure and non-equilibrium perturbations, such as temperature fluctuations or vibrations, which are known to impact the stability and performance of such systems.This proposal seeks to evaluate a novel microfluidic approach for the rapid phase mapping of a model formulation. We select a ternary mixture of SDS, water and butanol for this demonstration, since its phase diagram has been coarsely determined.

title: Anionic surfactant induced desorption of cationic surfactants from anionic surfaces

description: In this proposal, we request beamtime to study the unexpected behaviour of a strongly bound bilayer of the cationic surfactant didodecyldimethylammonium bromide on the anionic mica surface in the presence of the anionic surfactant sodium dodecyl sulfate. This builds on previous work at ISIS where a cationic surfactant layer was found to be persistent to an extended wash with water and salt solutions, but upon exposure to sodium dodecyl sulfate at the critical micelle concentration the layer completely desorped from the surface.

title: Forest-wide bird survey at 183 sample sites the Andrews Experimental Forest from 2009-present (Reformatted to ecocomDP Design Pattern)

description: This data package is formatted according to the "ecocomDP", a data package design pattern for ecological community surveys, and data from studies of composition and biodiversity. For more information on the ecocomDP project see https://github.com/EDIorg/ecocomDP/tree/master, or contact EDI https://environmentaldatainitiative.org.

This Level 1 data package was derived from the Level 0 data package found here: https://portal.edirepository.org/nis/mapbrowse?scope=knb-lter-and&identifier=4781&revision=2

The abstract below was extracted from the Level 0 data package and is included for context:

Bird occurrence data collected at 183 sample locations within the H. J. Andrews Experimental Forest (HJA) from 2009-present. We used a stratified, systematic, random design to select sample locations. We stratified across elevation, distance to road, and habitat type (plantation or mature/old-growth forest). We conduct point counts on six separate occasions from May – July, which corresponded to spring arrival and subsequent breeding period for the majority of bird species at HJA. Surveys occur between 05:15h and 10:30h and each consists of a 10-min point count where we record all birds seen or heard. The species of all birds seen and heard are recorded as well as all individual squirrels, chipmunks and pikas seen and heard. Survey-level information is also collected at each point count and includes: weather and wind conditions, stream noise, snow cover on the ground, phenology of vine maple and rhododendron. Data collection is ongoing.

title: Parkes observations for project P574 semester 2018OCTS_06

description: We request time to observe 260 pulsars on a regular basis in order to provide the accurate ephemerides necessary for the detection and characterisation of gamma-ray pulsars with the Fermi satellite. The main science goals are to increase the number of known gamma-ray pulsars (both radio loud and radio quiet), to determine accurate pulse profiles, and to characterise their high energy (phase-resolved) spectra. In the radio, the observations will also allow us to find glitches, characterise timing noise, investigate dispersion and rotation measure variability, and enhance our knowledge of single pulse phenomenology. To date, we
are (co-)authors on 70 papers arising from the collaboration and P574 data. The data have contributed to the PhD theses of students from Bordeaux, Stanford, Swinburne and Oxford.

title: High-throughput phenotyping of salt-stress responses of the selected Arabidopsis hormone mutants

description: This data was collected using Hight Throughput Phenotyping machine (psi.cz) purchased by KAUST in January 2018. The plants were germinated and grown under 12/12 light/dark light regime, 22C, 60% humidity for two weeks. After two weeks, half of the plants were exposed to approximately 100 mM NaCl (protocol described in Awlia et al., 2016, Frontiers in Plant Sci, https://doi.org/10.3389/fpls.2016.01414). The rosettes of the plants were subsequently phenotyped using the Thermal Camera, RGB, and Chlorophyll Fluorescence camera (in this order). Chlorophyll fluorescence was measured after 15 minutes of dark adaptation using the "LightCurve2" protocol.

title: SH193711.07FU

description: UNITE provides a unified way for delimiting, identifying, communicating, and working with DNA-based Species Hypotheses (SH). All fungal ITS sequences in the international nucleotide sequence databases are clustered to approximately the species level by applying a set of dynamic distance values (<0.5 - 3.0%). All species hypotheses are given a unique, stable name in the form of a DOI, and their taxonomic and ecological annotations are verified through distributed, web-based third-party annotation efforts. SHs are connected to a taxon name and its classification as far as possible (phylum, class, order, etc.) by taking into account identifications for all sequences in the SH. An automatically or manually designated sequence is chosen to represent each such SH. These sequences are released (https://unite.ut.ee/repository.php) for use by the scientific community in, for example, local sequence similarity searches and next-generation sequencing analysis pipelines. The system and the data are updated automatically as the number of public fungal ITS sequences grows.
