title: Ionic diffusion via oxygen vacancies and interstitial positions in layered Ruddlesden-Popper nickelates: A high-temperature study

description: Rare-earth nickelates Ln2NiO4+δ (Ln = La, Pr, Nd) with perovskite-related layered Ruddlesden-Popper (RP) structure are promising mixed ionic-electronic conductors (MIEC) for high-temperature electrochemical applications such as dense MIEC membranes for oxygen separation and oxygen electrodes for solid oxide fuel/electrolysis cells. The objective of the proposed study is to provide an insight on the changes in oxygen diffusion mechanism on a gradual transition from oxygen excess to oxygen deficiency in the RP structure occurring on substitution of lanthanum by strontium in La2-xSrxNiO4+δ. To this end, the neutron diffraction patterns of three compositions (x = 0, 1.0 and 1.6) will be collected at room temperature, 700°C and 900°C and analyzed by a combination of Rietveld analysis and maximum-entropy method to reveal the dominating pathway of oxygen-ion diffusion.

title: Characterization of a water rich-feature in a new multicomponent membrane (gCN/PTI mixed with Nafion) for energy applications.

description: Proton exchange membranes (PEM) are essential components of devices where it is required to transport H+ while blocking the flow of other ions and molecules used as reactants. Although Nafion (the most common material) has excellent H+ conductivity, it also exhibits poor selectivity. Research is underway to develop alternative membrane systems, including materials that can be combined with Nafion to enhance performance. We have successfully integrated either graphene oxide (GO) or graphitic carbon nitrides (gCN/PTI) and found that the presence of these components modifies the water dynamics with a consequent enhancement in performance. We are now focusing on the correlation between the nanoscale arrangement of composite PEMs and their role in the proton conduction mechanism.

title: To investigate the complex magnetization state in the paramagnetic gap of Ni2Mn1.4In0.6 Magnetic Shape Memory Alloy

description: Magnetic shape memory alloys (MSMAs) have gained immense attention due to their technologically important properties, which are closely linked with the magnetostructural phase transition. In this proposed experiment, our aim is to investigate the magnetic structure in the paramagnetic gap of Ni2Mn1.4In0.6 MSMA using temperature-dependent neutron diffraction. The measurements will be done in the temperature range of 10 K to 400 K during heating. Our initial results of muon spin relaxation measurements indicate a spin ordered state in the paramagnetic gap of Ni2Mn1.4In0.6 MSMA and neutron diffraction is necessary to establish the magnetic ground state of the martensite phase.

title: A structural study of amino acid salts to elucidate their role in carbon capture

description: A current major challenge is the large released of carbon dioxide (CO2) into the atmosphere leading to climate change. There is considerable interest in amino acid salts as an alternative solvent for the absorption of CO2 into a solvent such that carbon can be stored, and later released for useage. We aim to achieve a molecular level structural understanding to the superior performance of potassium amino acid salts compared with sodium amino acid salts, and aid in the intelligent design of future CO2 capture solvents. This will also serve as a crucial foundation to a host of future studies of carbon capture solvents, is of fundamental importance to the entire carbon capture solvent community and is particularly timely in the context of the Net Zero Strategy proposed by the UK government.

title: Neutron diffraction study of the emergent magnetic phase in the vicinity of a quantum critical point in CeRhAl4Si2 single crystal

description: At zero field, CeRhAl4Si2 undergoes two successive AFM transitions at TN1 = 14.2 K (incommensurate) and TN2 = 8.4 K (commensurate), respectively. Upon applying a magnetic field, the first-order transition of TN2 is continuously suppressed at the critical field of 5.5 T parallel to the c-axis. On the other hand, the smooth suppression of the second-order transition of TN1 terminates at a tri-critical point of 6.6 T and 4.7 K, with subsequent splitting into two phase-boundary lines revealing a novel M-phase. This phase is further suppressed by the critical field of 7.2T, giving rise to a quantum critical point (QCP). We, therefore, propose the neutron diffraction study on CeRhAl4Si2 single crystal with magnetic field B // c-axis to investigate the field-induced multiple phase transitions with particular attention to the novel phase emerging out of the quantum spin liquid state near the QCP

title: Measuring the size of a neutron wave packet

description: Quantum particles, such as electrons and neutrons, can produce interference patterns similar to those observed with light waves in the famous Young's two-slit experiment. Even though each particle must pass through only one slit, it must sense the presence of both slits in order for the interference pattern to be formed. Within the framework of quantum mechanics, this phenomenon is "explained' by representing each particle as a wave packet of a particular spatial extent. Several experiments have been carried out to measure the wave packet width for neutrons with results varying up to 80 microns. Our goal is to use the SESANS method on Larmor and a diffraction-grating sample to improve current measurements, utilizing the fact that SESANS is inherently less sensitive to conventional resolution effects.

title: Controlling Structure Formation of Polymer Brush/Gold Nanoparticle Composites by Ion-Specific Effects

description: Nanotechnology is abundant in numerous applications of our daily life. However, as the large variety of applications increases in complexity and specificity, the demand of tailored and individually structured solutions grows constantly. Therefore, processes that allow flexible fabrication with a fixed set of variables attract increasing interest. One realisation relies on driving the system into the desired structure via a series of trapped states. We aim to explore a model process for designing composite materials: controlling the structure formation of a gold nanoparticle assembly in a pre-formed polymer matrix. The model stimulus is presented by the immersion of the composite material in a salt solution. Thereby, different salts (ion types) induce different nanoparticle structures. The observed property is the vertical structure (perpendicular to the surface) inside the material.

title: Magnetic neutron diffraction in the novel triangular lattice antiferromagnet ErTa7O19

description: Rare-earth (RE) based geometrically frustrated magnets represent a promising avenue in the search of enigmatic quantum spin liquids (QSLs). Our previous study published in Nature Materials has identified a novel family of RE heptatantalates RETa7O19, where in the Nd case strong Ising anisotropy on the triangular lattice leads to a QSL state. As the nature of the RE has a strong influence on the magnetic anisotropy, which primarily determines the ground state on frustrated lattices, we hereby propose to study ErTa7O19 with the same crystal structure but twice as strong magnetic interactions and apparently XY magnetic anisotropy, according to our bulk magnetic measurements. Neither these nor specific-heat measurements show any signs of magnetic ordering down to 2 K. We propose a neutron diffraction study below 1 K to address the nature of the ground state in this compound.

title: Monitoring effect of RH fluctuations in easel painting canvases using neutron radiography

description: The aim of our work is to further investigate the effect of moisture sorption resulting from treatment using novel nanocellulose-based consolidants as an alternative to lining and the use of common adhesives.Some measurements by neutron radiography have already been conducted using the neutron imaging beamline, IMAT, ISIS Neutron and Muon Source UK, to determine the spatial distribution of moisture during programmed cycles of sorption and desorption in these canvases. A custom-built sample cell was built and this was connected to an RH controller so that the same programmed RH cycles were imposed on samples as in dielectric and mechanical studies. Some modifications have now been made to the application of the nanocellulose formulations to limit moisture sorption during the application.Work is proceeding in collaboration with practising conservators, also on a range of canvas materials

title: Water and Counterion Structuring around Cyclic Anionic Surfactant Micelles in Solution

description: In the detergent industry, anionic surfactants such as Sodium Dodecyl Sulfate (SDS) and Linear Alkylbenzene Sulfonate (LAS) dominate the market. Whilst LAS has been proven to be biodegradable, it is derived from petrochemicals using acid catalysts that cause low selectivity, corrosion of equipment and toxicity. The first aim of this proposal is to study the water and counterion structuring around the benzene sulfonate headgroup. We hypothesise that water structuring will help us to understand how the aromatic ring influences LAS interactions with water interfaces, and thus the origin of its superior detergent properties. We also aim to investigate a new class of anionic surfactants Oleo-furan Sulfonates (OFS) containing a furan ring instead of the benzene ring to compare the effect of different aromatic ring components on water structuring.

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: Structural determination of organogelated gases as a function of temperature using SANS

description: Low Molecular Weight Organogelators (LMWOs) are small molecules which self-assemble in a solvent (oil) matrix to form supramolecular structures, yielding a gel. This has led to envisaged use in oil-spill clean-up/remediation. LMWOs self-assemble using intermolecular forces such as hydrogen bonding and van der Waals interactions, and to be successfully depolyed in oil, they either have to be dissolved in a carrier solvent or heated.This work seeks to characterise a new class of organogels; namely those with a liquefied gas solvent matrix. Using a new approach developed in the Bear group, we have overcome the need for a carrier solvent or heating, and have successfully gelled both liquefied propand and butane gas. This experiment will be the first meaningful data on this new class of material, and will inform further developments and give valuable insight into how such materials form.
