title: SH0964052.09FU

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.

title: Neutron diffraction to monitor the state of a non-stoichiometric solid employed in chemical looping

description: An unmixed reaction is a dynamic process in which e.g. a metal oxide (which acts as an oxygen-carrier material) is used to e.g. provide oxygen for a reaction during which the oxide itself undergoes reduction.  The reduced oxide or metal is then reoxidised in a second step.  Here we perform reoxidation with water in order to produce hydrogen.  We intend to look at the state of reactor beds after use in chemical looping.  These will be frozen and powdered after operation under inert gas to minimise surface reorganisation and changes in bulk oxidation states.  The beds for characterisation will be obtained after an oxidation half cycle, a reduction half cycle and, for reference, after 12 hours exposed to a water to hydrogen ratio of unity.  This will allow us to determine the average oxidation state of surface and bulk materials after operation.

title: Crystal symmetry change at the magnetic transition in MnB and FeB compounds predicted by density functional theory

description: The "magnetocaloric effect" (MCE) is based on the entropy difference encountered when themagnetic state of a material is changed and it can be used for refrigeration. However, in a reverseprocess a magnetocaloric material can also be used to directly convert heat to electricity. Theefficiency of such a thermomagnetic generator can be as high as 55.5% of Carnot efficiency.Our recent investigations revealed a sharp (first order type), but non-hysteretic (second order type) magnetic transition in manganese monoboride, which suggest tricriticality, an essential feature of reversible magnetic phase transitions with large entropy changes for applications such as magnetic cooling. Finding its origin is a useful step towards designing new functional magnets.

title: Phase transitions in RbBi2Ti2NbO10

description: Ferroelectric materials, in which the polarization may be switched, are an important class of compounds due to their academic and technological relevance. The mechanisms that give rise to the polarization include cation displacements, cation ordering patterns and combinations of octahedral rotations. There has been much interest recently in materials that show hybrid-improper ferroelectricity, in which two non-polar lattice distortions (e.g.  octahedral rotational modes) give rise to polar structures. We have recently investigated some Dion-Jacobson oxides in which the width of the perovskite blocks influences whether the ferroelectricity will be of a proper, or an improper nature. We propose to investigate the new material RbBi2Ti2NbO10 and its structural behaviour as a function of temperature to understand the driving forces for proper and improper mechanisms for ferroelectricity.

title: Structural and magnetic characterisation of new room temperature polar-magnetic materials

description: A new generation of low-power high-density information storage would be enabled by the development of multiferroic materials which function at or above room temperature. Such materials are rare, as they require polarisation P (usually arising from d0 cations such as Pb and Ti) to be coupled with spontaneous magnetisation from long-range magnetic ordering M (usually arising from unpaired d electrons in cations such as Fe3+) within a single phase material. Even where these antagonistic properties can be combined it is difficult to maintain the magnetic properties at room temperature; it is thus desirable to develop new approaches to combining P and M at high temperatures. We aim to use neutron powder diffraction to investigate new routes to the design and synthesis of new polar/ferroelectric materials that are magnetically ordered at room temperature.

title: Magnetic structure of magnetocaloric manganites

description: Magnetic cooling has recently become the focus of cooling system technology as it boasts important advantages in terms of power consumption and for the environment e.g. not releasing gases that are harmful to the ozone layer. For magnetic cooling, materials exhibiting a strong magnetocaloric effect (MCE) are required.Here we propose a full structural and magnetic characterisation of the (La1 xPrx)0.85Ag0.15MnO3 (0.0 ≤ x ≤ 0.3) system using powder neutron diffraction (PND). We plan to uncover the underlying magnetic structure, in particular the magnetic moments carried by the different ions and also whether there exists an antiferromagnetic phase at low temperatures. This will help us understand the microscopic origin of changes of the macroscopic MCE effect in (La1 xPrx)0.85Ag0.15MnO3.

title: Development of Residual Stress during Flow Forming of Stainless Steel Type 15-5PH

description: Flow forming is a cold forming process used for the production of dimensionally accurate near net shaped hollow components used in various fields of industry. Due to the nature of the process, generation of residual stresses are inevitable. The objective of this study is to investigate the generation and distribution of residual stresses in flow formed components, to understand the evolution of stresses during the process. During flow forming process several catastrophic failures have been observed to occur that are believed to be related to the progress of residual stresses.  The aim of this study is to monitor the progress of residual stress in components after different levels of deformation by flow forming.  Due to the nature of martensitic steel, the microstructure might undergo strain induced phase transformation under high plastic deformation, which will be explored in this study.

title: Muons for Energy Nanonics

description: In order to improve the performance of future energy devices, nano-structured materials is one of the most promising routes. LiFePO4 is a commercial battery cathode material where nano-structuring is of specific interest due to its anisotropic crystal structure where the Li-ion diffusion occurs in 1D channels. In this experiment we propose to systematically study the microscopic Li-ion diffusion in nano-structured LiFePO4 samples. With our synthesis protocol we are able to produce high-quality nano-platelets with tunable size as well as selectable internal direction (!) of the 1D ion channels. This will allow us to obtain samples with well defined length of the ion channels as well as ratio with respect to the nano-platelet surface area. The results will be correlated with our parallel studies of the surface phonon spectrum in the same samples acquired by inelastic neutron scattering.

title: Large deformation and mechanical effects of damage in polycrystalline materials studied using neutron diffraction and modelling

description: Metallic materials are widely used in industry. It is now classical to develop numerical simulation for their manufacturing processes in ﬁnite transformation and this is one of our laboratory specialities. In order to improve the predictivity of ﬁnite elements analysis (FEA), it is necessary to provide accurate constitutive models for mechanical behaviour, such as multi scale modelling. But measurements at small scales are not easy to obtain, especially measurements of damage. The aim of the present work is to develop experimental techniques and data treatments to study damage mechanisms (and necking) at small scale for polycrystalline materials, and identify the damage parameter evolution by families of grains orientation, for micromechanical modelling.

title: Spin Dynamics Study on the Organic Magnet lambda-(BEDT-STF)2MCl4 (M=Ga, Fe)

description: One of strongly pi-d interacting systems in organic material is lambda-(STF)2MCl4 (M= Fe, Ga) (STF is C10S6Se2H8: bisethylenedithiodiselenadithiafulvalene). Ga compound doesnt have d-spin and it is a good target to study a pure pi spin properties in the conduction band of the STF two-dimensional sheet. It is a pressure induced superconductor above 1.2 GPa with Tc~5 K. At ambient pressure, it shows insulating phase which we expect that it is a quantum spin liquid candidate from our NMR and susceptibility data down to 1.6 K. If we change Ga to Fe which has 3d spin, it shows antiferromagnetic ordering at 16 K, evidenced by our NMR data. But the effect from d-spin to p-spin (ordering?) is not experimentally clarified yet. We want to study how spin liquid-like behavior in Ga compound is broken by introducing d-spin in Fe compound, which competes with pi-spin, by ZF and LF muSR.

title: Neutron Diffraction analysis of prehistoric copper alloy artefacts from Italy

description: This proposal is part of TEMPI, a two-year Marie Slodowska-Curie project at Newcastle University (2015-2017).The wider project seeks to reassess the development of early metalwork in Italy from ca 4500 to 2000 BC through a combination of radiocarbon dating and new artefact classification criteria which take into account the technological transformations undergone by the objects during their life-cycles. The experiment involves 18 copper alloy prehistoric artefacts from the British Museum collections. Main goals of the experiment are: a) to reconstruct the technological alterations of the objects with the spatially resolved maps of composition and crystallographic texture obtained through Neutron Diffraction analysis; and b) to compare and contrast these results with data previously gained from the same objects through an optical microscopy technique, Wear analysis.

title: Quantitative measurement of muonium photochemical reaction kinetics of TIPS-Pn in DCM

description: Our first completed photo-musr experiment on 6,13-bis(tri-iso propylsilylethynyl) pentacene (TIPS-Pn) has recently been accepted for publication. We observed a significant light-induced change in amplitude of one of the ALC resonances. The timescale of this light-induced change corresponds to two known transient species. We have interpreted this as a modification of the chemical reactivity of the molecule and Mu as a result of the excitation. However, all of our results to date are qualitative. We have thus far only been able to show that there is an increase in the muonium reaction rate as a result of the excitation, but we have been unable to say how large the increase is. Given that the reaction should be diffusion limited, and that we need to estimate the reactivity of each adduct independently, we plan to perform is a concentration dependent measurement of ALC amplitude.

title: A study of Line Broadening of the Muonium RF Signal in the Presence of O2 Spin Exchange

description: Considerable work has been carried out at ISIS with the aim of studying muoniated radicals in the gas phase by RF techniques. This has been motivated both by a desire to establish the method, a 'first' for any kind of magnetic resonance, and the unique possibility of measuring muoniated radicals with no nuclear moments in the gas phase. Despite this attention, we have been unable to measure the RF signature of a radical formed in the gas phase. By measuring a model system, this proposal seeks to understand this result. The proposal will also test a new analytical solution to the double quantum transition, which predicts this should provide a sensitive probe to spin exchange relaxation.

title: Structure and magnetism in Sr2IrO4 - benefits of 193Ir use

description: We plan to investigate the use of the isotope 193Ir for studies of magnetism in iridium containing materials using Sr2IrO4 as a test case. This isotope is important for neutron diffraction studies of iridium containing compounds because it has a smaller absorption cross section than natural iridium. Sr2IrO4 is an important material in condensed matter physics, displaying a novel Jeff=½ Mott insulating state and being a rare comparative system for understanding the high temperature cuprate superconductors. We have already investigated the benefits of 193Ir in studying the crystal structure of Sr2IrO4 using HRPD to elucidate the details of the octahedral distortions (critical to the electronic structure and magnetism in this material). We will now investigate the use of 193Ir for improved studies of magnetism in iridium-containing compounds using WISH, again with Sr2IrO4 as a test case.
