title: Crystal and magnetic structures of the high pressure RMnMnReO6 (R = La, Pr) double double perovskites

description: We have recently discovered a new RMnMnReO6 series of double double perovskites; they are of particular interest for magnetic properties as they contain magnetic cations at all four of the AA’BB’O6 sites (when R3+ is magnetic). The R = Nd material was discovered first and has recently been studied at WISH (RB2220431). We have synthesised two new RMnMnReO6 (R = La, Pr) materials that are proposed for study here. The magnetic susceptibilities of RMnMnReO6 (R = La, Pr) show ferrimagnetic transitions at ~135 K for R = La and at ~225 K for R = Pr, and further investigation on R = Pr using AC susceptibility clearly indicates successive magnetic transitions at 60, 160, and 225 K. Neutron diffraction is necessary to investigate the crystal and magnetic structures of these double double perovskites. With time for temperature changes and sample equilibration, as well as considering the small amounts of sample available (100 mg each, combining several batches from high-pressure synthesis), 3 days of beamtime are requested at WISH.

title: On the internal structure of modified starch particles

description: Oil in water (O/W) emulsions can be stabilized by adsorbing particles at the oil/water interfaces, i.e. the so-called Pickering type emulsions.1 Starch particles have been used to stabilize O/W food emulsions. Starch particles modified by esterification with dicarboxylic acids to give octenyl succinic anhydride (OSA) starch is an approved food additive that can be used to stabilize oil in water emulsions used in foods and drinks. Unfortunately, the chemical quantification methods can only assess the average total degree of modification but not the location of the modification. In this study, we plan to make use of chain deuterated octenyl succinic anhydride (provided DMAX at ESS) and isotopic contrasts to locate the modification. This knowledge is essential for the understanding the interfacial behavior of the starch particles. Preliminary SANS data from D11 at ILL shows that it is possible to perform SANS measurements on these samples. We expect to use the ZOOM instrument at ISIS that are able to reach sufficiently low q for the size of the particles.

title: Elucidating the hierarchical structure of feruloylated arabinoxylan hydrogels with small-angle neutron scattering

description: Upgrading agricultural waste into valuable food ingredients is fundamental from environmental and economic perspectives. We have produced polysaccharide gels from wheat and corn bran with structural stability and nutritional benefits. However, their gelling properties differ, making it necessary to understand their distinct network assembly mechanisms to exploit their properties fully. These gels have a hierarchical organisation that can only be fully resolved by combining Neutron and X-ray small-angle scattering. The results of this study are fundamental to extending the applicability of plant-based food products.

title: Hydrostatic pressure effects on the magnetic structure and critical behaviour of the quasi-two-dimensional S=1 antiferromagnet BaNi2V2O8

description: We propose to study the hydrostatic pressure effects on the critical behavior of the S=1 honeycomb antiferromagnet (AFM) BaNi2V2O8 which we found to be an ideal physical realization of a quasi-2D AFM over a wide temperature range in vacuum. Depending on the temperature regime, BaNi2V2O8 behaves as a 2D XY, 2D XXZ or 2D Heisenberg magnet. In the 2D XY regime BaNi2V2O8 reveals signatures of Berezinskii-Kosterlitz-Thousless (BKT) criticality. Because T_BKT estimated in BaNi2V2O8 be lower than T_N, the quasi-ordered state of vortex/anti-vortex pairs is hidden by long-range magnetic order so that only signatures for the decomposed vortex/anti-vortex pairs were experimentally observed just above T_N. Thus, searching for the experimental tool which can customize T_N, T_BKT and the 2D XY regime making BKT phenomena easier experimentally accessible in quasi-2D solid-state magnets, such as BaNi2V2O8, is an important scientific task. Here, we propose to explore the hydrostatic pressure effects on magnetic structure and critical exponent of BaNi2V2O8, to probe the hydrostatic pressure effects on critical bahaviour in quasi-2D magnets for the first time to our knowledge.

title: Competing surface and bulk anisotropies in TbCo films

description: Amorphous TbCo is a ferrimagnet which is well known for its strong perpendicular magnetic anisotropy (PMA). It is central to many devices involving spin-orbit torque, all-optical and thermally induced magnetization switching. In order to achieve the PMA needed for these applications, the thickness of the film needs to exceed a value. This critical thickness depends on the properties of the alloy, such as the size of the anisotropy and magnetostatic energy. However, it has been shown that this critical thickness also depends on seed and/or capping layer, where a significantly lower critical thickness can be achieved by using heavy metals. The dependence of the magnetic properties on the seed and capping layer hints at the existence of an interface layer which does not exhibit PMA. By studying different spin configurations in TbCo thin films with different seed/buffer layers, we will determine the origin of this effect, which in turn will facilitate the optimal design of magnetization switching in this important material system.

title: Imaging a newly discovered giant fossil marine reptile flipper with extensive soft tissues and bone-like serrations

description: Ichthyosaurs were a highly successful group of ancient marine reptiles whose fossils have been studied for more than 200 years. Here we focus on a recently collected, ~1.2 m long, articulated forelimb with a virtually intact soft-tissue outline. This unique fossil includes the first known soft parts of Temnodontosaurus, a giant 10–12 m long apex predator of the Jurassic seas. The fossil illustrates – for the first time – and contrary to all other marine tetrapods (both extinct and extant ones), that the distal fin was unsupported by skeletal elements and that the trailing edge contained bony serrations embedded in the skin. We propose to combine two imaging techniques (using neutrons and X-rays) to better understand the distribution of the soft tissues, to identify important skeletal elements and to visualise the unique 3D dermal ossifications. The expected results will greatly assist in our understanding of the hunting behaviours of this enormous ichthyosaur and whether its unusual forelimb anatomy, combined with its gigantic eyes, helped it to rely on stealth while hunting under the cover of darkness using powerful night-vision.

title: Stable Water: The case of water-in-salt electrolytes

description: So-called 'water in salt' systems have been suggested for use as novel electrolytes, as it has been shown that the water is stable at far higher operating voltages than in bulk. Before looking at these systems in applied operating fields, it is important to examine the effect on the electrostatic and spatial confinement of the salt itself on the water. In that spirit, this proposal aims to use the VESUVIO instrument to examine the single particle dynamics of the proton in successive dilutions of the water-in-salt system.

title: Lithium battery morphology: Examining the lithium deposition structure upon cycling using in-situ measurements

description: Current battery research is an area of significant worldwide interest motivated by our need to change to a green economy. One pressing issue is the stability of lithium batteries. The growth of dendrites, which are spiky, tree like structures, cause significant battery degradation and eventually lead to shorts and can cause fires. In this work we will use small angle scattering to probe these structures during battery operation under different conditions to better optimise the design of such batteries.

title: Uniaxial strain tuning of the structural instabilities associate with the 1/8th anomaly in the high-Tc cuprates.

description: Competition exists in the high-Tc cuprates between the superconducting (SC), pseudogap and ordered charge density wave (CDW) states. A key doping level for understanding these competitions has been the 1/8 doping level, where an anomaly in the superconducting dome occurs (e.g., La2-xBaxCuO4), that is concomitant with a first order structural phase transition and is understood to supress 3d superconductivity. However, very recently we have shown that this structural phase transition does not run to completion, suggesting a natural explanation for the persistence of only 2D (in plane) SC at the 1/8 anomaly. Building on our recent theoretical predictions, we propose a single crystal in situ strain field experiment on WISH to tune the competition between these phases. Our results will provide a greater understanding of how the 3D superconducting state can be stabilised to higher temperatures in the high-Tc cuprates.

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.
