title: Characterization of nanoparticles diluted in a solvent employed for the development of nanoscintillator detectors

description: We will study the total cross section of a system of nanoparticles diluted in a solvent, which is of interest in the development of nanoscintillator detectors. Nanoparticles of LaF3 activated with Ce, Yb and Gd diluted in a transparent medium are potentially useful for the detection of thermal neutrons and gamma radiation, by absorption of the neutron by the Gadolinium with the subsequent emission of a cascade of high-energy gammas, converted to visible light by the Yb and Ce atoms in the detection range of commercial photomultiplier tubes. Interaction of neutrons in such diluted systems produces a SANS effect, with a quantifiable contribution in the total cross section, that can be used to characterize the average size of the particles. Although this method has been little studied to date, it is an alternative for rapid characterization, in addition to the known SANS technique.

title: The structure of benzene in liquid ammonia: the search for N-H··pi hydrogen bonding

description: Hydrogen bonding systems are characterised by short X-H···A interactions. Such bonds have traditionally been associated with atoms such as X = O, N, S and A = O, N, S and halide, and have a strong electrostatic component arising from the highly dipolar nature of X-H bonds. Beyond the traditional hydrogen bonding interaction, the highly polarised nature of the X-H bond allows the electron rich pi-system of an aromatic ring to act as a hydrogen bond acceptor. Such O/N/C-H···pi interactions have been found in the solid state for both small molecule and biomolecule crystals and are now recognised as contributing significantly to molecular recognition and protein folding. In this proposal we will investigate the structure of benzene dissolved in liquid ammonia. By exploiting extensive isotopic substitution and the extended Q-range on NIMROD we will investigate the structural environment around the aromatic, and in particular the detailed nature of the N-H···pi hydrogen bonding and the 3-dimensional distribution of the solvation shell.

title: Designing Nanostructured Porous Polymers for Gas Sensing in Health Breathalysers

description: Volatile organic compound (VOC) detection holds great promise for medical diagnosis, including lung cancer, by analysing the exhaled breath of patients and thus paving the way for “breathalysers” that collect airborne molecules for analysis, cutting timescales and cost compared to conventional biopsies. Such approaches however require meticulous design of polymeric adsorbing materials. This work seeks to examine the demixed solution pathways, coarsening and kinetic arrest that can underpin the predictive design of polymer-based gas sensors compatible with prescriptive health requirements.

title: High pressure phases of Na2SO4

description: We request 3 days of beamtime on the PEARL diffractometer to study the structural properties of sodium sulfate, Na2SO4, at pressures up to 5GPa and temperatures up to 750K. In addition to confirming the presence of phase boundaries published in the literature, the experiment aims to solve the currently unknown structures of three high pressure phases. Such information will feed into our understanding of the structural systematics within A2MO4-type compounds and also provide important insights into the nature of any disorder of the Na+ and/or (SO4)2- units at elevated temperatures.

title: Effect of LLPS on XoPR/membrane interactions

description: The role of Liquid-liquid phase separation (LLPS) in biology is increasingly recognised. Actin remodelling has been found to involve LLPS, which likely acts to upregulate critical proteins and adjust their activity. Intrinsically disordered protein XopR, has been found to trigger actin remodelling, and undergoes LLPS under a pH of 7.4. Here, neutron reflectometry will be used to determine the consequences of LLPS induction at SLBs by XopR alone in terms of the changes that may occur in the lipid bilayer (SLB restructuring), as well as the type of LLPS that takes place (2D vs 3D, and eventual correlations between LLPS domains. Also, the link between cell membrane stiffness (i.e., cholesterol content) and LLPS at the membrane will be investigated.

title: Powder and single crystal neutron diffraction study on Weyl semimetal NdCuGa3

description: Magnetic topological materials provide an important platform for realizing several exotic quantum phenomena, such as anomalous Hall effect (AHE), anomalous Nernst effect, and skyrmions, owing to the interplay between topology and magnetism. Antiferromagnetic (AFM) materials exhibit AHE due to the presence of nontrivial spin structures. NdCuGa3 crystallizes in a tetragonal structure with an AFM ground state (Néel temperature ~3.4 K). We observed a large AHE of ~1100 Ω-1.cm-1 at 2 K. From magnetic studies, it exhibits AFM to metamagnetic to ferromagnetic transitions under applied magnetic field. Therefore, a knowledge of the ground state and in-field magnetic structures of NdCuGa3 by neutron diffraction is imperative to understand the magnetic phase transitions and origin of large AHE. These promising results suggest the possibility of spintronic devices based on antiferromagnets with tailored noncoplanar AFM to ferromagnetic spin configurations.

title: Gelation of casein micelles with different origins observed by spin-echo small-angle neutron scattering

description: Dairy production has a large impact on the environment. Cheese has one of the highest amounts of greenhouse gas emission and land use among protein rich food products [1]. We are proposing a novel way to produce dairy products, namely, we will use yeasts to express the different types of milk caseins and assemble them into micelles. To verify the possibility of assembling the individual components into micelles, we would like to compare the structural properties of skim milk with reconstituted casein micelles. Small-angle X-ray and neutron scattering has been shown to be a suitable method to describe the internal structure of casein micelles [2][3]. However, upon acidification the primer casein micelles form networks. The resulted particles are too big to investigate with classical small-angle scattering. Spin-echo small-angle neutron scattering (SESANS) has been shown to be a powerful method to investigate the structure of milk upon acidification [4]. We would like to set up a set of experiment of skim milk, reconstituted casein micelles and micelles assembled from its components and investigate the evolution of structure by decreasing the pH by the means of SESANS.

title: Using neutron reflectometry to understand enhanced dynamic linewidth in a magnetic trilayer device (continuation)

description: We have studied magnetic damping of CoFe/Ag/CoFe multilayer films using ferromagnetic resonance spectroscopy. There is an anomalous linewidth enhancement, which oscillates with a period of around 1 nm as the Ag thickness is increased. Theoretical studies predict dynamic exchange coupling across non-magnetic spacers to affect the resonance linewidth; the enhanced damping in CoFe/Ag/CoFe may rely on the interlayer coupling which may be ferromagnetic or antiferromagnetic due to the well-known Ruderman-Kittel-Kasuya-Yosida (RKKY) mechanism. Our previous experiment found uniaxial magnetic anisotropy (UMA) may also play a role. The aim of this experiment is to determine the UMA and RKKY coupling strengths from depth-resolved vector magnetometry using polarised neutron reflectometry with polarisation analysis, to clarify interpretation of the anomalous linewidth behaviour in CoFe/Ag/CoFe.

title: The structure of Barium-Phospho-Tellurite glasses

description: Tellurite glasses are of interest for near and mid-IR optical devices due to their favourable physical properties. However, in producing glasses suitable for applications, it is necessary to include a number of different additives to tailor these properties for each particular use. Literature reports indicate that the addition of P2O5 increases the average tellurium-oxygen coordination number in the glass (the only example of coordination numbers higher than 4 in tellurite glasses that we are aware of) while our own studies have shown that the addition of BaO reduces it. We wish to confirm the unusual interaction between TeO2 and P2O5 in a series of binary glasses and investigating the effect of adding an alkaline earth modifier, BaO to this mixed network.

title: CsNiCrF6: using muons to probe multiple Coulomb phases

description: Coulomb phases emerge from highly frustrated materials, and have the property that local constraints (on, for example, charge states or spin orientations) can be mathematically represented as a divergence-free ‘flux’. CsNiCrF6 is a pyrochlore which has two different B-site ions in different charge states, which contributes to this compound having three different Coulomb phases. This has been measured before with neutrons, but we suspect that muons will form F--mu--F states in these materials, and will be affected by the spin fluctuations in a unique way. This will enable us to uncover more information about the magnetic fluctuations from a local perspective, shining more light on the nature of the Coulomb phases in this material.

title: Probing nanoscale features of electrospun amorphous solid dispersions

description: Electrospinning allows the formation of ultrathin films with great flexibility formed by polymer fibres of microscale width. The incorporation of drug into these fibres can enable the formation of amorphous solid dispersions (ASDs) in which drug is dispersed within the polymer matrix to inhibit the formation of crystalline forms which have reduced solubility. It has been found that electrospun ASDs which don't exhibit evidence of crystallinity by XRD do however contain nanoscale phase-separated domains of drug which are detectable by SANS. These domains become evident when samples are doped with D2O to generate high contrast between solvated polymer and drug domain. This study will use SANS to resolve the spatiotemporal evolution of these domains during dissolution in D2O with a view to linking polymer properties and drug chemistry to performance as a drug delivery vehicle.

title: Realising S = 1/2 Kagome Magnets in the Two-Dimensional Limit

description: Since the discovery of graphene, there has been vast interest in the mechanical and electronic properties of two-dimensional materials. However, the study of the magnetic properties of matter in two dimensions is challenging due to the limited materials and methods available. The S = 1/2 kagome magnet is a prime example of a fascinating two-dimensional model of magnetism that is yet to be realised. We are exploring the experimental routes to this model in exfoliated metal-organic nanosheets. Here, we seek to confirm the magnetic ground state of an unexfoliated parent structure by powder neutron diffraction.
