title: Structures formed by rhamnolipids and polysaccharides in the presence of mono- and bi-valent salts

description: Rheology modifiers are used to alter the viscosity of products in order to change their flow. In order to make more sustainable products, the traditionally used oil-derived polymers used to alter rheology can be replaced by polysaccharides. For the role of polysaccharides in formulation to be optimised, interactions between them and other formulation ingredients must be analysed, and factors such as natural structural variation must taken into account in such analysis. The aim of this study is to investigate the structures formed between the polysaccharide, xanthan gum, at different acetate/pyruvate ratios and rhamnolipids - a bio-derived, sustainable surfactant - in the presence of sodium and calcium chloride. Elucidating the interactions between these ingredients will allow the optimisation of their use in formulations for home and personal care products.

title: Determination of incommensurate magnetic structure in a stacked triangular quantum antiferromagnet

description: We propose neutron powder diffraction measurements to determine the magnetic structure in hexagonal Na2BaCoP2O8, which is a rare example of a frustrated easy-axis triangular antiferromagnet. In recent neutron single-crystal diffraction on WISH we observed a rich phase diagram with a succession of phases in applied longitudinal field, including a magnetization plateau phase and a phase with a field-dependent incommensurate propagation vector. In zero field the magnetic propagation vector corresponds to a three-sublattice in-plane order with an incommensurate propagation between layers, however the magnetic structure could not be solved in detail due to complexities in correcting the single crystal time-of-flight diffraction peak intensities. Here we propose to collect a powder diffraction pattern to obtain a reliable and quantitative parameterization of the zero-field magnetic structure to distinguish between competing magnetic structure models and also determine the absolute value of the ordered moment.

title: Determining the Néel and Brownian relaxation times in Co-Mn mixed ferrite nanoparticles

description: Cancer treatment by magnetic hyperthermia using superparamagnetic nanoparticles (SPM NPs) is in great attention in recent years. Unfortunately, there is no explicit dependence of the heating performance of NPs on the size, shape, or chemical composition. Nevertheless, all aspects modify the anisotropy constant, which is a crucial parameter to determine the Néel relaxation - one of the processes of heat generation by the SPM NPs. Half-polarized small-angle neutron experiments enable us to access the spatially resolved effective anisotropy constant and give us access to the hydrodynamic size of NPs, which are crucial parameters to determine Néel and Brownian relaxation times, respectively. Thus this study aims to unveil the magnetic structure of SPM NPs and correlate it with the magnetic NPs' heating performance.

title: Active control of polariton dynamics in biomimetic plexcitonic antenna complexes

description: A scientific ’grand challenge’ over the past two decades has been to achieve efficient long-range transport of excitons (electron-hole pairs formed by the absorption of photons) in molecular materials. We are developing a new approach to the design of molecular photonic materials that combines biologically-inspired design principles with the exciting new physics of strong light-matter coupling. This approach requires anchoring of, and 3D arrangement of dye molecules at interfaces. As such, surface-grafted polymers (a.k.a. brushes) are grown from interfaces and subsequently derivatized with reactive dyes. In a previous proposal we functionalised a polymer brush with a deuterated dye molecule (deuterated Nile Blue, d-NB) and examined the role of reaction conditions and polymer brush structure on the distribution of these dyes throughout the brush. Through contrast matching, we were able to resolve the distribution of the dye molecules. In this proposal we expand on our previous work and introduce functional groups into the polymer structure to impart stimulus responsive behaviour. It is our aim to examine how the distribution of dye molecules, and the structure of the film, change actively controlled through stimulus response

title: Establishing the incommensurate magnetism in single crystals of Cr1/3TaS2

description: Noncentrosymmetric systems lack a centre of inversion, which can lead to interesting magnetic phenomena. Cr1/3TaS2, a chiral helimagnet which has been shown to host a chiral soliton lattice, i.e., 360 degree domain walls separated by regions of ferromagnetism, in an external field. However, an incommensurate chiral helimagnetic state has yet to be confirmed with neutron diffraction. In our previous proposal, neutron diffraction measurements on Cr1/3TaS2 indicate an incommensurate phase is present, which could be the fingerprint of chiral ordering. Due to the limited time, small sample size and small moment of Cr1/3TaS2 we could not get the required statistics necessary to fully resolve the incommensurate magnetism. Here we propose a continuation experiment to use single crystal diffraction measurements of Cr1/3TaS2, as well as the high resolution possible for WISH time of flight measurements, to more fully resolve the incommensurate magnetism in this system.

title: Inelastic neutron scattering study in the triangular antiferromagnet NaErSe2

description: Non-long-range ordered magnetic state known as spin liquids are of paramount importance in both fundamental and applied science. A classical state of this kind was predicted for the Ising antiferromagnetic triangular model but such material is still rare to date. Although the recent discovered rare-earth magnet REMgGaO4 (RE: Rare Earth) provides a new opportunity to examine the exotic phenomenon, the nonmagnetic Mg-Ga site disorder has an adverse effect on the identification of deconfined spinon excitations from the intrinsic sample synthesis issues. Recently, the triangular-lattice rare-earth-based materials NaRESe2 naturally removed the issue of Ga/Mg site-mixing disorder in REMgGaO4, which will make us better understand the observed spin-excitation continuum in NaRESe2. A representative material NaErSe2 is an ideal platform for the research of quantum spin liquids and its promising applications. Here, we intend to study such magnetic fluctuations by using the inelastic neutron scattering technique. The outcome will help us better explore the magnetic properties of quantum spin liquid candidate NaErSe2.

title: Single-crystal neutron scattering of an intermetallic skyrmion lattice candidate

description: Current data storage technologies are expected to reach their fundamental limits before the end of this decade. Newer technologies are necessary, and much promise is shown by memories based on exotic magnets. One such memory technology is based on magnetic skyrmions, which are stable nanoscale swirls of magnetic moment that can be controlled by small electrical currents. Only a few dozen materials hosting skyrmions are known, and here we intend to expand this list. We have found that an intermetallic compound of tin and a lanthanide metal may host magnetic skyrmions, and to conclusively determine that, we propose to do single-crystal neutron scattering measurements at ISIS WISH, and determine the magnetic structure of the material.

title: SANS investigation of helical antiferromagnet Co1/3NbS2

description: The antiferromagnet Co1/3NbS2 shows an unexpectedly large c-axis anomalous Hall effect (AHE) in a narrow temperature range below TN. To date, little is known about the corresponding magnetic structure dominating its AHE amplitude, although a helical structure is speculated, and our preliminary uSR study has confirmed two distinct magnetic phases below TN. In this proposed SANS experiment, our goal is to verify the existence of the helical phase and search for the possible emergence of other topologically non-trivial magnetic structures, i.e., magnetic skyrmions.

title: NEUTRON BRAGG EDGE IMAGING (NBEI) MEASUREMENT OF AXIAL STRAINS IN A W/Cu/CuCrZr MONO-BLOCK DEVELOPED FOR PLASMA-FACING COMPONENTS IN FUSION REACTOR TECHNOLOGY

description: It is proposed to utilize Neutron Bragg Edge Imaging (NBEI) to measure the axial strains in a W/Cu/CuCrZr mono-block sample fabricated as a prototype of the divertor, a crucial plasma-facing component in fusion reactor technology. This sample is constituted by a CuCrZr cooling pipe 1.5 mm thick, brazed by a thin, Cu alloy layer to a protective pure W tile. Complex strain distributions are expected around the joining region and inside the CuCrZr pipe; therefore NBEI is the appropriate technique to carry out such investigation with the spatial resolution needed to allow for a meaningful comparison with numerical strain predictions. Un-strained references both for W and for CuCrZr will be measured as well to correct the data measured on the brazed mono-block sample. The obtained axial strain distribution through the sample will provide essential information needed to qualify the adopted fabrication method and its suitability for the construction of large scale divertor components.
