title: Investigation of the Competitive Adsorption between Monoclonal Antibodies and Non-ionic Surfactants at the Air-Water Interface

description: We aim to gain insight into protein-surfactant complex behaviours at the air-water interface. Specifically, we will investigate two mAbs, supplied by Eli Lilly, with different long-term stabilities and the non-ionic surfactant Poloxamer 188. We propose to investigate the the competitive adsorption between the two components and how it varies based on order of addition and compression/expansion cycling which can represent some conditions seen during formulation and drug administration. This study has high industrial impact and would improve therapeutic formulations to evaluate how well this new surfactant can prevent interfacial mAb aggregation, which can reduce drug efficacy and shelf-life. Neutron reflectivity, alongside a Langmuir trough, can be used to characterize this interface under compression. The experiments will be complemented with other interfacial measurement techniques.

title: Delineating perceived vertebrate remnants from the early Jurassic of Sweden

description: The Triassic-Jurassic extinction, occurring c. 200 million years ago, resulted in the demise of approximately 30% of animal and plant life. Here our aim is, with the help of neutrons, to delineate the internal remnants of a remarkably preserved fossil shark egg case. This would be the first time such an object is being analysed using neutron tomography. The discovery of an indisputable shark embryo could breed future research into the reproduction and nursing strategies of extinct hybodont sharks.

title: Covalency induced energy scale entanglement in Pr4+ compounds

description: Lanthanides, which typically exist in a trivalent oxidation state, possess filled 5s and 5p orbitals which shield the 4f electrons from surrounding ligands. As a result, the 4f electrons are typically only weakly perturbed by the crystalline electric field (CEF) and the spin orbital manifolds are well-separate. However, the tetravalent lanthanides show qualitatively different behavior to their 3+ counterparts. The key ingredient is the hybridization of the central ion’s f orbital with the valence p orbitals of the ligands, which contrasts with the ionic bonding found in Ln3+ systems. This covalency affects both the single ion energy scales and the inter-ion interactions, leading to anomalous magnetic behavior. In this proposal we aim to investigate the low energy magnetic excitations in Pr4+ compounds where the poor separation of energy scales and anomalously small magnetic moment may give rise to novel quantum magnetic phenomena.

title: Investigating Micro and Nano-Scale Pathways for Enhanced Underground Hydrogen Storage Efficiency

description: Hydrogen is a clean energy carrier that is a key part of the global transition to a low-carbon energy future. However, its lower volumetric calorific value than other gaseous fuels means that better storage solutions are needed. Underground hydrogen storage (UHS) has emerged as a solution to overcome limitations in surface storage capacity and discharge capabilities. Understanding the porosity and pore size distribution at the micro- and nanoscale in geological formations is crucial for optimizing UHS efficiency. We propose using SANS along with other imaging techniques to find basic answers about where pores are located and how they connect at the micro- and nanoscale for UHS. Statistical insights into pore structures will guide the development of models linking microporosity and fluid flow pathways during UHS, facilitating a more accurate assessment of storage capacity. Samples from diverse geological formations will undergo meticulous analysis, requiring SANS2D and well-established techniques to determine pore size distribution and fractal behavior within the samples. This multidisciplinary approach is crucial to comprehending UHS efficiency and paving the way for sustainable hydrogen storage solutions.

title: Interfacial contribution to the measured spin Seebeck effect in La0.7Ca0.3MnO3 thin films

description: The spin Seebeck effect (SSE) is an exciting phenomenon for next generation energy harvesting, which is often observed by measuring the voltage generated in a thin Pt layer on the magnetic layer. It is critical to probe the impact of structural and magnetic morphology of SSE materials for technological realisation. We have reported on the temperature dependence of the SSE and the magnetisation in La0.7Ca0.3MnO3 (LCMO) and the SSE voltage show significantly different variations indicating that in addition to the bulk, there might be an interfacial contribution to the SSE. Since identifying the role of the interface in the SSE is important to improve the efficiency of spintronic and SSE based devices, we propose using PNR to determine whether there is a subtle change in the interfacial magnetisation that enhances/impedes the SSE.

title: Superfluid density and strange metallicity in the overdoped regime of the cuprate Bi-2201

description: Identifying the origin of cuprate high-temperature superconductivity remains one of the outstanding challenges of modern condensed matter physics. Key to this challenge is to understand why both the superconducting transition temperature Tc and superfluid density trace out a dome as a function of doping. This project focusses on the overdoped side of the dome in what is known as the strange metal regime, characterized by anomalous transport, maximal (Planckian) dissipation and strong electron correlations. Our comprehensive study of the single-layered cuprate Bi2201 within this regime has provided compelling evidence for the coexistence of two distinct charge sectors; one conventional and Fermi-liquid-like, the other non-Fermi-liquid-like and defined by an anomalous T-linear resistivity and this ‘Planckian’ dissipation. Given the presence of these two charge sectors, the crucial question is which sector contributes most to the superfluid density? The prospect of having a superfluid condensate composed exclusively of these Planckian carriers would represent a new paradigm for high-temperature superconductivity. In order to provide a definitive answer to this question, we seek to carry out the first detailed investigation of the superfluid density across the strange metal regime via μSR measurements of the in-plane penetration depth in Bi2201. This proposal represents the first stage of this project, focussing on two well-characterized single crystals with different Tc values.

title: Local structure and dynamics in lithium borohydride

description: Lithium borohydride, LiBH4 is one of the promising materials for hydrogen storage due to its high gravimetric and volumetric hydrogen densities of 18.5 wt.% and 121 kg H2/m3, respectively, way above the 5.5 wt.%, regarded as the target for onboard hydrogen storage by the US Department of Energy (DOE). Solid LiBH4 has been attracting much interest as a material for renewable energy applications, first as a potential high-capacity hydrogen store and, more recently, as a solid-state lithium-ion conductor due to its superionic conductivity at high temperature. Despite the flurry of research activity, there still remains some degree of uncertainty regarding the local structure and dynamics of LiBH4, especially in the high-temperature phase. LiBH4 is an orthorhombic crystal (space group Pnma) at ambient temperature and pressure and is known to undergo a phase transition at around 380 K, but the crystal structure of the high-temperature phase and local dynamics of hydrogen, boron and lithium in this phase was subject to debate. In order to shed more light on the local dynamics of the BH4- unit, as well as the Li ion dynamics, in both the low and high-temperature phases of LiBH4, in this work, we propose to concurrently employ neutron Compton scattering (NCS), neutron transmission (NT), and neutron diffraction (ND) on VESUVIO spectrometer.

title: Phonon anomalies and structural instabilities in TbScO3 (SXD)

description: Distorted perovskite TbScO3 is a particularly interesting lanthanide scandate, exhibiting a dramatic flexoelectric effect, along with the common features of the wider family of lanthanide scandates. Accurate knowledge of its structure and dynamics is of particular importance, for example due to its use as a substrate for epitaxial growth of high-quality perovskite thin films. However, the structure and dynamics of this material at low temperatures are not properly understood. We plan to investigate these by combining phonon studies with powder and single crystal neutron diffraction. Powder diffraction on HRPD and single crystal diffraction on SXD will be used to study structural models and characterise subtle distortions of this material. Phonon spectrometry on MERLIN – preceded by careful phonon characterization using CASTEP with Horace and the Euphonic package – will be used to clarify discrepancies between phonon modes allowed by symmetry and those previously experimentally observed.

title: The impact of high pressure on the vibrational spectrum of molecular organic semiconductors

description: The van der Waals nature of organic semiconductors (OSCs) offers low cost processing while intermolecular vibrations affect their charge transport properties. By using inelastic neutron scattering and terahertz spectroscopy, combined with quantum mechanical simulations, we have characterized for the first time the full-spectrum of low-frequency motions in several OSCs, identifying the long axis sliding motion as the killer phonon mode. Within this framework, the aim of this proposal is to push our study further and investigate the impact of pressure on the vibrational spectrum present in these soft materials. This will allow us to 1) understand the impact of pressure on the thermal disorder in OSCs, 2) elucidate how the killer phonon modes are hampered as a function of molecular design and packing, 3) test if there is a critical pressure value at which killer phonon modes are affected and, 4) develop potential pressure/strain strategies to improve transport properties in these soft materials.
