title: Comparison of Lattice Vibrations in LCO and LNO

description: The purpose of this application is to measure the Li and Ni/Co phonon modes in lithium-ion battery cathode materials, namely LiCoO2 and LiNiO2. Lithium-ion batteries that have high energy densities are enabling the transition from petrol and diesel vehicles to electric vehicles. However, the capacity we can gain from lithium-ion batteries is approaching a ceiling. New approaches to increase capacity involve substituting the Co content in the cathode for Ni. Recently published work from our group suggested that in the Ni-rich archetype LiNiO2 cathode, Ni migrates from the fully dense transition metal layer and accumulates at the surface of the particles upon charging, leaving vacancies on the transition metal site. This reduces the performance of LiNiO2. This is not observed with LiCoO2 which also has better battery cycling stability.
We wish to probe this mobility indirectly using inelastic neutron scattering. By observing the Ni phonon modes over a large temperature range we will be able to deduce whether Ni is more mobile than Co. There is also a dearth of INS experimentation on cathode materials in the literature, this study on two basic layered cathode materials will be the first step to rectify this.

title: Stochastic dynamics in corannulene and its flat counterpart perylene

description: We have recently discovered the emergence of dynamically disordered solid as well as fluid phases in the carbon-based �buckybowl� corannulene, a finding of direct relevance for the development and subsequent deployment of a new class of mesoscopic media for the storage of thermal and chemical energy. Building upon our recent works [see Carbon 183 196 (2021) and Carbon 155 432 (2019)], this proposal seeks to complete our work on corannulene in the liquid and supercooled states, and to extend it via the study of perylene, its flat and isobaric counterpart. In combination with other experimental data and computer simulations, these results will be used to establish the effects of molecular curvature on the transport properties and behaviour across their stable and metastable phases, and link this information to the emergence of stochastic motions and diffusion in both solid and liquid.

title: Modelling hydrogen in BeO using muon spin resonance

description: Little is known about the solubility, diffusivity and electrical activity of interstitial hydrogen in beryllium oxide, a material considered for a number of highly demanding applications. We plan to use the positive muon as a model for hydrogen. Existing muon spin rotation experiments show a large "missing fraction" due to thermalisation at early times. We will use muon spin resonance to measure the final fractions in each muon state as a function of temperature, confirm the hyperfine constant as seen in high TF data, and measure any coupling to nuclear moments.

title: Quantum diffusional dynamics of H_2 molecules in low-temperature liquid mixtures: a QENS study

description: Various quantum dynamics simulation techniques are being developed in view of their application to many scientific areas including Physics, Material Science, Chemistry, and Biology. Inelastic neutron scattering from binary mixtures of semi-quantum liquids have been shown to provide valuable and unique data for assessing the performances of such computational methods. However, the low-Q regime, and in particular the diffusional dynamics, has not been explored yet. We propose to fill this gap with a QENS study of the peculiar H_2 diffusion mechanism in Ne-H_2 mixtures at T=30 K.

title: Operando PND Investigations of the Ammonia Synthesis Mechanism over Co3Mo3N and Co3Mo2.6W0.4N

description: Co3Mo3N has previously been shown to be capable of catalysing the synthesis of ammonia via a Mars-van Krevelen mechanism, utilising lattice nitrogen as part of the process. This study aims to understand differences in activity when tungsten is doped onto the molybdenum sites by examining nitrogen mobility and exchange of 15N. An operando neutron diffraction study is ideal to probe these effects due to the strong scattering ability of nitrogen and the contrast between normally abundant nitrogen and 15N.

title: Evolution of the crystal structure of the layered oxysulfide Sr2MnO2Cu5.5S4

description: This is a proposal to probe subtle structural changes in a layered oxysulfide, Sr2MnO2Cu5.5S4 over a wide temperature range and characterise the driving force for these transitions. This compound is being probed as a potential thermoelectric material and a full understanding of the subtle changes relating to the Cu/vacancy distribution and disorder in the sulfide layer and electronic transitions in the manganese oxide layer will be key to full understanding of the physical properties.

title: Surface and shape modification effects on structural organization of magnetic nanoparticles in cellulose derivatives

description: Progress in additive manufacturing technologies during the last decade is intrinsically connected with developing and improving multifunctional inks. The modern era challenges raise additional requirements for ink formulations and printing processes, specifically for them being environmentally friendly, sustainable, and less expensive. One of the key properties affecting the performance of the printed sensors is the nanoparticles' distribution in the sensitive layer. In our current proposal, we continue our systematic research and aim to uncover the influence of particles' surface charge and shape anisotropy on the structural properties of both nano- and micro-thick films. The microfilm/support interface can be investigated using neutrons only, by directing the beam from the side of the silicon substrate (solid-solid mode). Thus, neutron reflectometry is an invaluable tool for probing morphology in the studied system.

title: Probing Amorphous Energetic Materials Using Inelastic Neutron Scattering

description: Energetic materials (explosives, propellants and pyrotechnics) play important roles in both military and civilian applications. Their sensitivities to initiation by impact, shock, friction and spark are crucial not only for their performance, but also for safety in manufacture, processing, storage, transport, and operational use. We have recently developed a sensitivity-prediction model based on a vibrational up-pumping theory and this has been applied to a range of structurally diverse energetic materials with variable sensitivities. The model accounts for the ease with which the vibrational modes of the crystal can channel the energy from a mechanical impact through the low-energy phonon bath modes to reach the molecular vibrations. A fascinating recent development has been the discovery that amorphous energetic materials (prepared through techniques such as spray drying) are substantially less sensitive to mechanical initiation than the crystalline form. This has the potential to open up new avenues for the preparation of energetic formulations that are less sensitive to accidental initiation and are thus intrinsically safer. This lack of crystallinity precludes the direct calculation of phonon densities of states and so we are seeking to obtain these directly through experimental measurements of INS spectra. This will allow us to to assess vibrational energy transfer and hence make predictions about sensitivity that can be correlated with experimental measurements.

title: In-Situ investigation of Residual stress and Crystallographic Texture Evolutions of 17-4 PH Stainless Steel during High temperature Annealing

description: The 17-4 PH stainless steel has wide range of applications in power plants, marine, and chemical industries due its good mechanical properties and corrosion resistant. Although, producing 17-4 PH alloy via Additive Manufacturing (AM) technology has great advantages, numerous undesired results encountered. During selective laser melting (SLM) process, high temperature gradient can be generated within the AM produced part as a results of high energy input at local scanning points leading to increased residual stresses. Furthermore, the residual stresses promote premature failures of the mechanical parts used in services. Therefore, it is critical to investigate the residual stresses generation during 3D printing and understand the recovery mechanism during post processing heat treatment. The SLM scanning strategy parameters have a great influence on the generated microstructure, texture and post fabrication treatments. Therefore, it is important to investigate the SLM scanning strategy and post processing parameters influences on residual stress generation and texture evolution. Here we will particularly focus on understanding the effect of different 3D printing scanning path and post processing parameters. Each of these scan paths will result in a different residual stresses distribution and microstructure/texture evolution during printing and post processing.

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.
