title: Lateral roughness correlations in 11B4C incorporated Fe/Si polarizing neutron mirrors

description: The incorporation of 11B4C in multilayer thin films has been shown to significantly decrease the roughness between layers in our studies. This effect is now being applied and studied in neutron optics. The most common polarizing neutron mirror material system today is Fe/Si. Decreasing the interface roughness between the layers can be done by incorporating small amounts of 11B4C in all layers. With this proposal we aim to study the lateral magnetic roughness of Fe/Si+11B4C multilayer systems in comparison to Fe/Si without incorporated 11B4C. We expect the 11B4C to reduce the lateral roughness and magnetic correlations, and therefore plan for such long counting times, to carefully observe any differences between Fe/Si with and without incorporated 11B4C.

title: Complex magnetic ordering in the topological kagome metals RMn6Sn6 (continued)

description: Recent theoretical predictions and experimental realisations of exotic fermions and topologically protected phases in condensed matter have led to tremendous research interests in topological quantum materials. Recently, the correlated topological metals RMn6Sn6 have emerged as an exciting platform to explore the interplay between geometric frustration, non-trivial band topology and magnetism. We have carried out the first single-crystal neutron diffraction study of ErMn6Sn6 at WISH in early April 2022. However, due to limited beamtime in our previous experiment, we could not complete all originally proposed studies. Therefore, we would like to propose to carry out a continued study of complex magnetic ordering in ErMn6Sn6, including the magnetic field dependence measurement with H//c and the zero-field crystallographic study. We would request 3 days of measurement time at WISH.

title: Morphological analysis of the 2-handed long sword of Great Pier, a folk-hero of early 16th Century Frisia

description: Pier Gerlofs Donia or Great Pier was a 15th Century farmer from the Frisian town of Kimswerd. He became part of the folk army that was partly funded by the duke of Gelre. He died during battle and became a legend. Starting in the 19th century, this Grutte Pier history turned him into a Frisian folk hero. He had a sword more than two meters long he stole from a Saxon soldier. His sword became famous and has been in the collection of the Fries Museum in Leeuwarden since 1882. "Once and for all" is a television program about historical objects from Dutch History made by POSVIDEO/IDTV on behalf of Dutch Public Television. The second season will consist of six episodes and will be broadcast in fall 2022. Episodes focus on historic objects. One is dedicated to the Great Pier long sword and would include the neutron imaging analysis carried out on IMAT, to determine the sword authenticity.

title: NR investigation of the SARS-CoV-2 Spike protein fusion domain interaction with model membranes

description: Coronavirus disease-2019 (COVID-19) is a lethal respiratory illness caused by the coronavirus SARS-CoV-2. A thorough understanding of the molecular mechanisms of cellular infection by coronaviruses is therefore of utmost importance. A critical stage in infection is the fusion between viral and host membranes, which is mediated by the viral Spike Protein. It has now become clear that membrane fusion during viral entry is a cooperative process likely involving the contribution of different sections of the fusion domain, which may also be dependent on the nature and the composition of the lipid mixtures. To address this, we will employ NR to investigate the membrane binding activity of the Fusion domain and Core of the Spike S2 domain, upon interaction with natural lipid bilayers and compare these results with our previous findings involving minimal models with single peptides.

title: In Situ Study of Lithium Dynamics in Li, Li-In and Si Anodes of Solid-State Batteries by Neutron Imaging

description: All-solid-state batteries (ASSBs) with a ceramic solid electrolyte (SE) and a lithium metal anode aim for higher energy density and better safety than conventional liquid Li ion batteries. However, challenges related to the lithium metal anode including lithium dendrite formation during lithium deposition and battery polarization increase during lithium dissolution impede their practical application. In situ/operando neutron imaging makes it possible to dynamically track the Li distribution and structural change inside the ASSBs, therefore, promises to reveal the lithium deposition/dissolution mechanisms. In this work, we will implement in operando neutron radiography and in situ neutron tomography to study 1) dendrite growth mechanism of Li anode and lithium concentration evolution in solid electrolyte, and 2) lithiation/delithiation of Li-In alloy and micro-Si.

title: Probing the solid and liquid state structure of organic ionic plastic crystal formamidinium triflate

description: This is a Disordered Materials XPress request for the NIMROD beamline. Organic ionic plastic crystals (OIPCs) are a family of solid-state materials with unique plastic mechanical properties that arise from the existence of crystalline states with various forms of disorder (rotational, translational, or both). They can be used as electrolytes and in barocaloric refrigeration. Critical to the design of new OIPCs is understanding of the structure-property relationships that underpin these dynamics; it is therefore critical to elucidate the structure of the plastic crystal phases of OIPCs. An organic salt/ionic liquid, formamidinium triflate, has recently been found to exist in a plastic crystalline state between -3 °C and 100 °C. The aim of the proposed neutron scattering experiments is to elucidate the structure and interactions in both the plastic crystalline and liquid phases.

title: The Skyrmion Lattice and Other Non-collinear Spin Structures in Centrosymmetric GdRu2Si2

description: Skyrmions in magnetic materials are two-dimensional vortex-like spin configurations with an integer topological winding number. GdRu2Si2 is a centrosymmetric material, in which a skyrmion lattice has recently been discovered using resonant elastic x-ray scattering. In this experiment, using WISH and a sample of 160-GdRu2Si2, we intend to examine the full range of non-collinear spin structures that are present in the phase diagram. This will include studying the field and temperature driven evolutions between the nanometric-skyrmion lattice, fan phase, screw phase and a previously uninvestigated phase which we have detected. A comprehensive knowledge of all the magnetic states in GdRu2Si2 will be invaluable for any model of the complex magnetism in this material.

title: Magnetic structure of Ho2Ru2O7 at low temperature

description: Pyrochlore iridates of formula R2Ir2O7 have been studied from the point of view of magnetic frustration as a way to stabilize new phases. In those compounds the Ir ions order in an all-in all-out configuration, which in turn produces a local all-in all-out magnetic field on the rare- earth sublattice site. This allowed the discovery of so-called fragmented phases, where order and disorder coexist on the r.e. site. By replacing the Iridium atoms with another magnetic ion like Ruthenium, we hope to find new fragmented phases. We focus on Ho2Ru2O7, where we identify a new magnetic structure for the Ru ions that was not reported in the literature. In this experiment we want to identify the magnetic structure of Ho2Ru2O7 down to dilution temperatures, measure the temperature dependence of the various ordered moment, and identify the proportion of Ho magnetic moment that may stay disordered.

title: Cadmium distribution and real-time movement in wheat using neutron imaging

description: Cadmium (Cd) is a toxic element. Food is the main source of Cd intake and wheat highly contribute. Agronomic measures ensuring a low Cd concentration in wheat grains are needed. Varietal selection could be an important tool to reduce Cd intake. Knowing the sources of genotypic variation in Cd accumulation and the physiological processes governing Cd accumulation in crops is required for a successful breeding program. Previous results showed that Cd distribution patterns varied seedlings from different wheat genotypes. They indicate that Cd adsorption at the root surface may be a key mechanism to keep Cd out of the plant. Using neutron imaging, we aim at collecting more detailed information about the Cd distribution pattern as well as the real-time Cd movement in the living plant. This will provide valuable information to improve our mechanistic understanding of Cd uptake by wheat.

title: SANS study of pH-induced structural alteration of lipid nanoparticles for gene delivery

description: We have studied lipid nanoparticles (LNPs) prepared from an ionisable cationic lipid, a helper lipid, a cholesterol and a poly(ethylene glycol) (PEG) lipid via a microfluidic system. This 4-component system mimics the LNP nanocarriers used in the delivery of COVID-19 vaccines by Pfizer and Moderna. Our recent studies have revealed vast variations in the transfection and expression efficiency of LNPs in both in vitro and in vivo experiments from substituting some ingredients with their analogs. Furthermore, pH environment also has a huge impact on their nanostructures. As LNPs are internalized via emdosomal cycling during which pH gradually becomes acidic, we request 3 days of SANS2D to undertake the proposed work and cover the widest Q range for better structural resolution,

title: Physico-chemical properties of xylans

description: Pulp and paper industry has a decisive role in development of sustainable future. Their products are not only fibers but also polymeric wood extracts such as hemicelluloses or polysaccharides. Wood xylans are polysaccharides consisting of xylose monosaccharide backbone that contains glucuronic acid substitutes Although the molecules are hydrophilic, the high molecular weight grades that are needed for engineered materials can be solubilized in water only to a limited extent or not at all, which limits general application of wood xylans. We will study dispersibility of xylans from different suppliers and in-house sample. The dispersibility will be studied in two solvents, DMSO and water. The different xylans varies in molecular weight, sugar substitution and uronic acid content. With this knowledge we will predict dispersibility of different xylans in solvents such as DMSO and water.

title: Temperature- and pH-dependent interaction between an alkyl ethoxylate surfactant and an acid azo dye

description: Alkyl ethoxylate surfactants (AEOs) are widely used due to their mildness and low toxicity. In aqueous solution, AEOs usually show a lower critical solution temperature (LCST). AEOs are nonionic and therefore not very sensitive to changes in pH or ionic strength. However, a pH-responsivity can be introduced by adding an acidic solute, rendering the system responsive to two triggers: Temperature and pH. Both parameters affect the mechanism of solubilization of the solute (e.g. dye molecules) and therefore its interaction with substrates (e.g. textiles, hair fibers). We will investigate the morphology of dye/AEO co-assemblies to understand the mechanism of dye solubilisation and its response to changes in temperature and pH. This will aid the targeted design of more efficient dyeing-systems.
