title: Qualification of Spark Plasma Sintering method for Industrial Scale Production of ODS Steels for Future Nuclear Reactors

description: The Oxide Dispersion Strengthening (ODS) Steels are candidate materials for future nuclear reactors such as in the cladding and tubing of high-temperature Gen IV fission reactors and the blanket surrounding the vessel of fusion reactors. The ODS steels with added nano-size yttrium oxides (Y2O3) provide resistance against irradiation, creep, and swelling. Continuous exposure of high dose neutron irradiation at extremely high temperatures transforms the nanoparticles into new complex oxides which degrades the mechanical properties and irradiation resistance; both conditions in nuclear reactor applications are ill-characterised. In this work, for the very first time, we will use thermally aged and irradiated ODS steels manufactured with Spark Plasma Sintering (SPS) to obtain the stability of nanoprecipitates and their coarsening characteristics. Underpinning the SPS-based consolidation process capable of safeguarding their use in the nuclear reactor life cycle by resisting ageing due to thermal and irradiation loads will lead to the qualification of the manufacturing of ODS steels for industrial applications and length scales.

title: First resolution of the structure of lung surfactant reservoirs at near zero surface tension and their inhibition by serum proteins

description: The structure of lung surfactant reservoirs, from which surfactant protein assists the resupply of lipid back to the surface monolayer to maintain low surface tension during expiration, has not been resolved experimentally to date. In our lab, we have been studying model lung surfactant systems held at surface pressures of 70 mN/m, close to zero surface tension, to understand the effect of peptide-mediated lipid transport at the air/water interface. A recent neutron reflectivity experiment on INTER allowed us to resolve the lipid reservoirs, but the experimental objectives were left incomplete due to 2 days of lost time, and the most novel measurements at 70 mN/m and using selective deuteration to resolve which component is expelled into the reservoir were not acquired. We have gone on to investigate effects of the serum protein fibrinogen on the inhibition of lung function, which is of relevance to acute respiratory distress syndrome experienced by patients as a result of COVID-19. This proposal aims to complete the measurements on reservoir structures with respect to the presence of Mini-B peptide and extend the study to fibrinogen interactions at a range of surface pressures. It is expected that the research, part of a final year PhD student's thesis, will result in two timely and high impact publications.

title: Real Time in-situ Mineral Carbonation for CO2 Utilisation and Permanent Sequestering - QENS tracking

description: We propose real-time in situ tracking of CO2-mineralisation reactions for long-term sequestering of CO2(gas) in carbonates. Both Na and Mg-carbonates are currently under investigation a the atomistic/nanoscopic, trhough meso- and micro-scopic to bulk scales. The output carbonates stabilise CO2 as solid-minerals [i.e. Na/Mg-CO3]; added-value products in the infrastructure, fertiliser, pulp&paper and other industries. Our work at the bulk scale involves the production of multi-kg scales of carbonates under industrial conditions and relevant raw-material (im)purities, with subsequent use as fillers/additives to concretes of standard sizes and subsequent compliance testing (ISO1920-4, size:15x15x15cm, compressive-strength). We seek to further resolve the fundamental phenomena and processes underlying the reaction kinetics and responsible for product identities and purities. In this case QENS measurements on OSIRIS/IRIS will provide valuable information on the manifold rotational (and other!) dynamics of these systems and processes.

title: Identification of hydrogen positions in doped BaCeO3 and SrCeO3 by neutron diffraction

description: Low temperature ionic conducting materials are important electrolytes for electrochemical devices such as electrolysers, fuel cells, electrochemical synthesis etc. 
Fortunately, during our research at University of Warwick, we have found that the perovskite oxides SrZr0.8Y0.2O3-, CaZr0.8Y0.2O3- and SrZr0.92Y0.08O3- exhibit mixed OH−/H+ ionic conduction at a temperature below 100 °C, which is a new property of these perovskite oxides. In order to figure out the ionic conduction mechanism, it is desired to identify hydrogen and the environment of hydrogen in the hydrated oxide samples. According to previous research, the position of hydrogen in perovskite oxides BaZr0.5In0.5O3- and BaSn0.6Sc0.4O3- can be identified through the analyses of difference Fourier maps derived from the neutron diffraction patterns of the deuterated perovskite oxides. This is demonstrated by the recent success of our HRPD Xpress measurements of Ba and Sr zirconates.
During our research, it is also found that mixed OH−/H+ ionic conduction is also found in doped BaCeO3 and SrCeO3. We need to figure out the conduction mechanism of doped cerates to see if they share the same ionic conduction mechanism to the zirconates. A key requirement for proposing conduction mechanisms is to identify the position of hydrogen in hydrated perovskite oxides. Hydrogen positions also inform the position of OH- ions in the structure therefore we request neutron diffraction beamtime.

title: Probing superconducting gap structure and time reversal symmetry state of SrPd2As2 and BaPd2As2 using muon spin relaxation and rotation

description: Recent observations of time reversal symmetry breaking in s-wave BCS superconductors have generated considerable interests in muon spin relaxation and rotation (µSR) investigations of s-wave superconductors. SrPd2As2, and BaPd2As2 are two such superconductors which exhibit superconductivity below the transition temperature Tc = 0.92 K and 3.85 K, respectively. The electrical resistivity and heat capacity measurements reveal electron-phonon mediated weak coupling type-II superconductivity possibly with an anisotropic s-wave gap. It would be of interest to further investigate the superconducting properties of SrPd2As2, and BaPd2As2 using µSR measurements to probe the superconducting gap structure and the time reversal symmetry state. We therefore propose to carry out µSR study on these compounds using the MuSR spectrometer.

title: Transferability in Moonshine

description: Transferability of interatomic potentials in molecular simulation is a core assumption upon which most forcefields are built. Yet, forcefields are often parameterised against limited experimental structural data in the condensed phase, or commonly none at all. We propose to investigate the structure of the ternary “moonshine” mixture at four compositions, performing full isotopic substitution on each of the three components. This will yield a rich dataset by which recent advances in multi-configuration simulation analysis implemented in the Dissolve software can be fully explored, with a view to forming coherent workflows for similarly large parametric studies which are anticipated to form a significant part of the SANDALS-II programme.

title: Assessing the protein conformation and surface activity in protein-based nanohybrids at the air/water interface

description: We aim to study the structure of interfacial layers formed thanks to the interaction between negatively charged silica nanoparticles (NPs) and bovine serum albumin (BSA). In particular, we will investigate how the dispersion composition (NP/BSA ratio and ionic strength) will affect the layer structure and density by means of neutron reflectometry (NR). Then, the monolayers will undergo a compression/expansion cycle in a Langmuir trough and, during both compression and expansion, NR will be performed. This will allow determining structural modifications of the layer upon mechanical deformation and associated eventual desorption/re-adsorption phenomena. This study will provide new fundamental insight to characterize and control the protein conformation at liquid interfaces. Moreover, it will allow assessing the use of mixed NP/BSA dispersions as novel green adaptive surfactants for stabilizing complex fluid interfaces.

title: Investigating the Impact of Tripeptide Doping on Gel Noodle Mechanics Using SANS

description: Supramolecular gels tailored into specific structures such as 'gel noodles' play a crucial role in advancing fields like biomedical devices and soft electronics. These gels, derived from small molecules (e.g., 2NapFF), exhibit unique properties in synthetic tunability and biocompatibility. However, they face limitations in mechanical strength. This proposal addresses this challenge by doping 2NapFF with a tripeptide 2NapFFD, which includes an additional carboxylic acid in the alkyl chain, to enhance the mechanical stability of the gel noodles through improved cross-linking. We have shown that the multicomponent system of 2NapFF and 2NapFFD favours self-sorting in aqueous solution, but the self-assembly can be tuned by external stimuli. The analysis of the mechanical properties of the gel noodles suggests an innovative approach to adjusting their stiffness and resilience by varying the ratio of 2NapFF to 2NapFFD. The use of SANS is pivotal in this research to elucidate the interactions of the peptides within the solution and the gel matrix. By selective deuterated labelling of 2NapFF, we will be able to isolate the scattering behaviour of 2NapFFD both in solution and in the gel noodles, providing critical insights into the molecular basis of the enhanced mechanical properties. This investigation not only seeks to advance our understanding of supramolecular gel systems but also promises to stimulate the development of next-generation materials for diverse applications.
