title: Coupled ammonia/water and polymer dynamics in a new polyamide membrane for Hydrogen production

description: Polyamides form a class of polymers with exceptional performance for a wide range of functional applications. Their properties are easily tailored by inducing morphological alterations by changing the synthesis pathway and/or conditions as well as incorporating flexible groups into the polymer backbone. Fully aromatic polyamides that have excellent high-temperature stability combined with tunable physical and chemical properties are increasingly used for a range of industrial applications. Here we will study a polyamide membrane that has already been established for reverse osmosis water filtration as an anion exchange membrane for fuel cell devices, with a specific focus on Hydrogen production via Ammonia cracking. The results will allow us to unravel the fundamental transport mechanisms to advance the design of high-performance membranes for energy applications.

title: Incommensurate magnetic strcture of Fe3Ga4 under zero and non-zero magnetic field

description: Due to potential application in future spintronic devices, studying the nature of topological magnetism has gained tremendous attention in recent times. Here, using the high resolution diffractometer, WISH, we aim at determining the complicated magnetic structure of one such compound, Fe_3Ga_4. This system shows finite topological Hall effect even above room temperature. The proposed experiment will shed light on the real (and reciprocal) space nontrivial spin arrangement, which results in such exotic effects. Along with addressing the contradicting arguments about the zero field state, we will go one step forward and try to resolve the magnetic field-induced spin textures. Due to the nature of topological magnetism observed in Fe_3Ga_4, results of this study will have impact on both fundamental as well as application oriented research in the field.

title: Native-like mitochondrial membrane mimics for apoptosis-regulating proteins

description: Mitochondrial apoptosis is a programmed suicide mechanism in cells essential for life. Upon oxidative stress, the mitochondrial outer membrane (MOM) undergoes permeabilization, followed by the release of apoptotic factors. This process is tightly regulated by the Bcl-2 protein family at the MOM. In healthy cells, pro-apoptitic Bax is neutralized by the anti-apoptotic Bcl-2, but any imbalance in this interaction can cause disorders including cancer. The MOM contains several phospholipid classes, including the mitochondria-specific cardiolipin, and a broad distribution of fatty acyl chains. We are using neutron reflectometry to elucidate the function of the Bcl-2 protein family and in this experiment we will recreate the MOM lipid composition from purified yeast lipid extracts to investigate the binding of Bax to native-like MOM mimics.

title: Understanding the magnetoresistance of a ferromagnetic metal-semiconductor bilayer

description: Spintronic devices using insulating materials offer new advantages for low-power information technologies. A potential material for such proof-of-principle devices is ferromagnetic EuS, which in contact with conducting ferromagnetic permalloy (Py) exhibits an intriguing multi-level magnetoresistance. There is evidence to suggest that this effect originates from a non-collinear alignment of the magnetisation in the two ferromagnetic layers. To obtain insight to the magnetoelectric behaviour and to find potential pathways for device optimisation, we aim to use polarised neutron reflectometry with polarisation analysis to determine the in-plane canting angle between the magnetisation in the EuS and the Py layers. By measuring this canting we can obtain coupling constants that further describe the complex longitudinal and transverse magnetoresistive response we observe in EuS|Py devices.

title: NR Study of Co-adsorption of a Monoclonal Antibody and Nonionic Surfactant at the Amphiphilically Modified SiO2/Water Interface

description: From spectroscopic ellipsometry and AFM studies of the adsorption of antibody COE-3 and nonionic surfactant Tween 80 at the UV-treated TMOS layer/water interface, large differences in the adsorbed amount for antibody and surfactant were observed from different adsorption sequences, indicating different impacts of local environments on molecular interactions. This neutron reflection work will help determine how COE-3 and surfactant mix in the adsorbed layer under different sequential adsorption processes. This study constitutes an important part of our systematic efforts to understand how surface chemical nature affects adsorbed mAb structures and causes structural deformation. We require 3 days of beam time for the proposed experiment. Inter is preferred for better structural resolution over the entire Q range and following fast dynamic adsorption processes.

title: Probing the nanostructure of regular versus gluten-free spaghetti

description: High quality gluten-free food alternatives are increasingly sort after as supplements for people requiring diets with low glycaemic indexes. The challenge to come up with high quality alternatives. Structure at the nanoscale highly related to the texture, quality, mouthfeel of the final product. We have previously performed structural characterisation of starch granules in gluten-free and regular pasta using small-angle x-ray and neutron scattering as a function of cooking time. These preliminary results showed a loss of internal structure as a result of cooking, in particular for the granules in the gluten-free pasta variety, i.e. not protected by the formation of a gluten network. We would now like to perform a more in-depth study with contrast matching and SANS, in order to investigate further the effect of cooking time and the effect of salt in the cooking water.

title: Spatial and temporal distribution of water in collagen and parchments by real-time neutron radiography

description: Parchment was widely used as a writing medium from the 2nd century BC until the 17th CE. Although parchment has demonstrated its longevity as a bearer of our written history, it is still be prone to damage leading to the loss of the artefacts. To date, there are no accepted methods available to conservators to repair parchment. Our proposal focuses on the re-engineering of natural glycation cross-links that are present in all collagens using methods translated from Tissue Engineering. Our consolidation approach focuses on binding water within the collagen fibrils by glycation, while restoring the ultrastructure of damaged fibrils using a novel Collagen-Filler Peptide (CPF). Here, we propose to quantify the spatial and temporal distribution of water resulting from our new consolidation treatment in both collagen scaffold models and in-situ archival parchments.

title: Liquid water on Titan: a structural study of ammonia-water solutions at low temperature

description: Titan is Saturn’s largest moon, and a target of NASA's Dragonfly mission. It is an icy world whose surface likely hosts periodic interactions between organic-rich dust, and water-ice melt, rich in ammonia. We are interested in exploring these interactions and the role of ammonia in the habitability of Titan, and ocean worlds in general. This study is designed to create a mimetic surficial melt of ammonia-water ice at STP and complements the research of the Dragonfly mission that will study organic dunes at Selk crater. Our initial objectives are to establish the extent of ammonia’s perturbation of water’s hydrogen bond network and the mechanism by which this is effected. The results of this experiment will inform the design of biological experiments that address how the ammonia in such a melt impacts the self-assembly of amino acids, and the hydration of biomolecules.

title: Roles of magnetic anisotropy and inter site exchange interactions in the temperature dependent magnetization reversal in NdMnO3 perovskite

description: Single crystal INS experiments at MERLIN (Exp. No. RB1820264, duration: 14-19 Feb 2019) were carried out on NdMnO3 to determine the magnetic anisotropy and inter site exchange interactions. The INS study has revealed spin excitations over 5- 21.3 meV along [H, 0, 0] and [0, -2, L], and over 3- 6 meV along [0, K, 0] corresponding to the Mn and Nd sublattice interactions. However, detailed low energy excitations are required to determine the Nd-Mn and Nd-Nd exchange interactions. We aim to understand the roles of single ion anisotropy and exchange interactions between Nd and Mn sublattices in magnetization reversal in NdMnO3 by carrying out additional INS measurements at LET to study spin excitations below ~2 meV. The proposed study forms first of its kind to reveal the microscopic origin of magnetization reversal phenomenon that is of technological importance in spin based devices.

title: The influence of cholesterol on the ability of ionisable cationic lipid to interact with nucleic acid in lipid nanoparticles

description: Lipid nanoparticles (LNPs) are increasingly being used to deliver nucleic acids and have reached world-wide prominence as the delivery vehicle for the COVID-19 vaccines produced by Moderna and Pfizer/Biontech. Yet few, if any, studies have examined the driving force for LNP self-assembly and, in particular, the structures formed as a result of the interaction of their nucleic acid cargo with the ionisable cationic lipid, MC3, and cholesterol, the components believed to comprise the interior of the LNPs. Preliminary surface pressure-area isotherms have shown strong effects of MC3 monolayers without/with cholesterol with nucleic acid in the subphase. The present study will exploit neutron reflectivity measurements on FIGARO to understand the effect of the helper lipid cholesterol on the ability of the MC3 lipid to interact with nucleic acid polyA.

title: Where scattering meets refraction in SESANS

description: For many scattering applications we ignore many other optical effects such as refraction, however techniques such as SESANS now probe length scales where refraction has also to be considered. We will use simple model systems (spherical particles of different diameters) to measure length scales which crossover from diffraction to refraction. This will allow us to determine how to describe such data and most importantly with this knowledge we can apply this to real world systems such as food and emulsions.

title: PNR of strain-mediated parallel to antiparallel magnetic switching of twisted LSMO bilayers on PMN-PT

description: Strain-mediated magnetoelectric (ME) coupling in ferroelectric (FE) and ferromagnetic (FM) heterostructures provides an exciting path towards the development of next-generation memory storage and sensing technologies. This proposal aims to use Polarized Neutron Reflectometry (PNR) to investigate ME coupling in twisted bilayers of La(1-x)Sr(x)MnO3 (LSMO) membranes stacked on giant piezoelectric (1-x)Pb(Mg1/3Nb2/3)O3-(x)PbTiO3 (PMN-xPT). The piezo-driven coupling between the LSMO bilayers and PMN-PT will drive the LSMO magnetic moments to switch from a parallel state to an anti-parallel state, which will be measured using the depth-resolved nature of PNR. This strain-mediated switching would not rely on the use of external factors (such as shape anisotropy) or a multi-step voltage application process and would garner broad interest in the multiferroic research community.
