title: Nano-Sized Effects on Spin Dynamics of La2-xSrxCuO4 Nanoparticles

description: Magnetic nanoparticles raised great attention in both fundamental and application aspects. The magnetic properties possess significant differences from that observed in the bulk case. In the case of high-Tc superconductor cuprates, La2-xSrxCuO4, a hysteresis loop at 300 K was observed when the particle size was reduced to 64 nm. Other non-magnetic nanoparticles reported similar behaviour but the reason for the appearance of magnetism is not well explained yet. In addition, in a high-Tc superconductor, it is believed that superconducting and magnetism are intertwined with each other which is proposed to explain the origin of the superconductivity. Here, we propose to study nano-size effects on the magnetic state and spin dynamics of La2-xSrxCuO4 nanoparticles.

title: The structure of spirit and the microscopic basis of the ‘Ouzo effect’

description: We request 1 day on NIMROD as a Disordered Materials Xpress proposal to determine the feasibility of conducting a systematic study of the structure of 40 % ABV ethanol-water-oil mixtures which serve as the basis for most commercially available spirited alcoholic beverages. To improve currently available formulations, we need to understand the microscopic physical basis for phenomena such as the ‘Ouzo effect’ (clouding of the mixture on addition of surplus water) and build a complete picture of these mixtures’ structural properties and their relation to fundamental interactions (H-bonding, electrostatics, etc.).

title: Amorphous precursors in the formation of the Metal—organic* *framework TRUMOF-1

description: Metal-organic frameworks (MOFs) are highly versatile materials with a range of applications, particularly in gas storage and separation. The architecture of a MOF is dictated by the geometrical nature of its building blocks. The combination of OZn4 clusters and 1,3-benzenedicarboxylate (1,3-bdc) linkers has led to the discovery of TRUMOF-1, a MOF with a unique aperiodic structure. Its structure - which can be described as a 3-dimensional Truchet tiling network - offers potential for information storage on an atomic scale like a QR code on a macroscale. Understanding the self-assembly of TRUMOF-1 during synthesis is critical for unlocking its full potential. We hypothesise that the combination of octahedral node coordination and bent linkers leads to frustrated oligomers in solution that precede eventual crystallisation into TRUMOF-1. To investigate this, we propose small-angle neutron scattering (SANS) studies of the crystallisation process. Together with parallel small-angle X-ray scattering measurements, these experiments will offer insight into the roles of the solvent, linkers and clusters during crystallisation, with the potential to inform the broader field of MOF nucleation and growth mechanisms.

title: Novel ground state in a rare-earth-based triangular lattice antiferromagnet

description: The subtle interplay between emergent degrees of freedom in rare-earth-based geometrically frustrated magnets represents a promising platform for the search for enigmatic quantum spin liquids (QSL). QSL state is characterized by the absence of magnetic ordering or freezing down to absolute zero, strong quantum entanglement, and exotic magnetic excitations. Our recent study on a novel class of structurally perfect rare-earth-based triangular lattice family revealed NdTa7O19 as a promising candidate for a QSL stabilized by the strong Ising anisotropy. Here, we focus on a novel triangular lattice antiferromagnet DyTa7O19 from this family. Our preliminary magnetization data do not show any signature of spin-freezing or magnetic ordering down to 1.9 K, while the specific heat shows an anomaly at ~1.5 K and another broad anomaly at 120 mK possibly related to phase transition. However, the entropy release at these temperatures is too low for conventional magnetic ordering. This calls for more sensitive local-probe magnetic investigations that could unambiguously determine the nature of the magnetic ground state and characterize the corresponding magnetic excitations at very low temperatures. Given the localized nature of 4f orbitals, the exchange interactions of this frustrated magnet are, as typically, in the sub-Kelvin range. Therefore, it is imperative to carry out the μSR experiment in the millikelvin range to establish the ground state and associate excitations unambiguously.

title: Is singlet oxygen efficient in oxidising organic films at silica/water interfaces for atmospheric mineral aerosol?

description: Organic molecules in haze, cloud and fog droplets may be oxidised by aqueous oxidants. Recent reports have demonstrated that singlet oxygen may exist in large enough mixing ratios in atmospheric particulate matter to be atmospherically relevant, but the rate of reaction is unknown and needed for to assess whether atmospherically important. A reaction with an atmospheric lifetime longer than 4 days is not important. A previous proof-of-concept solid-liquid neutron experiment by one of the proposers demonstrates that singlet oxygen oxidation of bilayer lipid films is possible and combined with an ISIS facility development student’s new solid-liquid cell that can measure the phosphorescence of singlet oxygen promises an elegant experiment.

title: Dynamics of hydration water on the hydrophobic surface of Polyoxymethylene

description: Interfacial water is ubiquitous, playing a crucial role in biology, chemistry, physics, materials and environmental science. How does the hydrophobicity of the surface affect the dynamics of hydration water and by how much? In our last contribution, we proposed that surface water presents a universal onset of dynamics at a common temperature on distinct material interfaces. We choose two simple polymers with similar structure but different hydrophobicity, i.e. polyethylene glycol (PEG) and polyoxymethylene (POM) to quantitatively investigate this. We performed QENS experiments on polyethylene glycol (PEG) on the IRIS spectrometers about 2.5 years ago, withe the results about to be published. In this proposal, we ask for time to run a similar experimental campaign on POM.

title: Looking back at the structure of pure liquid methanol

description: We request 4 days on SANDALS to acquire the complementary isotopically varied contrast for pure liquid methanol. In conjunction with synchrotron measurements on IN15-1 XPDF, we will test 3 established force fields, in addition to 3 more recent ones, to investigate more closely the subtle 
differences in structure arising from the use of different force fields. By looking at three temperature points, we aim to reinvestigate the propensity of methanol of forming chains and cyclic motifs, as well as the presence in solution of the overlooked CH···O weak hydrogen bonding via the methyl 
groups. We will then use the EPSR refined configuration as a starting point for molecular dynamics simulations, which will be critical to provide experimentally validated starting configurations for MD, to establish the life-time of the hydrogen bonds, and the presence of cooperative/anticooperative behaviour.

title: Neutron diffraction assessment at extreme temperatures to gain insights into the performance of thermocouple coatings

description: This project investigates the behaviour of Chromel-Alumel K-type thermocouples under extreme temperature conditions, focusing on coatings produced through thermal spray processes. These thermocouples, widely used in industrial and aerospace applications, experience phase changes that can compromise temperature accuracy, particularly in cryogenic environments. While bulk material behaviour is well-documented, the performance of thin films and coatings remains poorly understood, especially under high and low temperatures. The proposed study employs neutron diffraction to assess in-situ phase transformations and residual stress effects in Ni–20Cr coatings. Neutron diffraction's deep material penetration and high resolution make it ideal for probing changes across coating thicknesses. The project will investigate the influence of residual stress on phase transformations, contributing to improved thermocouple calibration and performance in cryogenic and high-temperature applications. By addressing these material challenges, the research aligns with ongoing UK government initiatives to digitalize manufacturing processes, building on previous EPSRC-funded projects and supporting the completion of a PhD thesis on thermal spray coatings with embedded sensing capabilities.

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.
