title: High energy spin fluctuations in low-tellurium-doped FeSe single crystals

description: Recently, we have grown low-tellurium-doped FeSe single crystals successfully by the chemical vapor transport method. Our previous inelastic neutron scattering measurements have revealed strong spin fluctuations at the stripe and Néel wave vectors in FeSe, both of which are strongly coupled with nematicity. The nematic transition temperature in FeSe decreases with increasing tellurium concentration, and a nematic critical point is further proposed by transport measurements. Tc exhibits a highly unusual non-monotonic behaviour, reaching a local minimum of about 6 K at the critical tellurium concentration ~ 0.3. To understand these exotic phenomena, studying Fe(Te,Se) from FeSe side, i.e., with low tellurium dopant level is important. In this experiment, we propose to map out the spin fluctuation spectrum and its interplay with nematicity and superconductivity in FeTe0.3Se0.7. MSLICE will be used to analyse the data. The success of the proposed experiment, combined with the previous results, will lead to a comprehensive understanding of the magnetic ground state and its relationship with nematicity and superconductivity in Fe(Te, Se) system and offer important indications on the roles of the stripe and the Néel spin fluctuations in iron chalcogenides.

title: Residual stress profiles in coated riveted joints of dissimilar materials using SPR joining technique

description: The United Kingdom has set a formidable net-zero target of 100% emission reduction by 2050, emphasising the urgent need for progress in sustainability efforts. Given the significant role of the automotive industry in CO2 emissions, there is a growing demand for lightweight multi-material structures to mitigate environmental impact. Carbon fibre reinforced polymer (CFRP) and Aluminium (Al) have emerged as pivotal materials due to their superior strength-to-weight ratio, particularly in the context of vehicle electrification. However, understanding and mitigating joint failure resulting from residual stresses in the Self-piercing riveting (SPR) process remains a critical area of investigation. Prior studies have successfully quantified residual stresses in SPR joints, primarily focusing on similar metallic materials. This current research extends the inquiry to encompass both dissimilar materials i.e. CFRP-Al with carbon steel rivet joint, with a particular emphasis on the resistance encountered during rivet insertion, potentially leading to stress-induced failures. Employing various coated rivets (carbon and Aluminium-based) with distinctive characteristics, this study aims to unravel the intricate interplay between surface properties, coating hardness, and residual stress formation during SPR joining, ultimately enhancing our comprehension of these critical structural elements.

title: Eu3Bi2S4F4: uncovering mysteriously suppressed superconductivity using F–µ–F states

description: Cuprate superconductors have attracted considerable research interest over the past few decades due to their high transition temperatures which 
allows superconductivity to be accessed at liquid nitrogen temperatures. In light of this, there has been considerable effort in finding materials with similarities to cuprates which may also exhibit superconductivity at high temperatures. One of the promising families of materials are those formed of BiS2-layers, which tend to have a crystal structure analogous to cuprates. One of the most recently discovered compounds which exhibits superconductivity is Eu3Bi2S4F4, which consists of Eu3F4 layers which crystalize into a CaF2-like structure (where the fluoride ions are in a simple cubic arrangement), sandwiching bilayers of BiS2. Polycrystalline samples of this material shows a superconducting transition below about 1.5K, but this is not present in single crystal samples. This experiment aims to find out why, by observing the way in which the F--mu--F state changes with temperature for both single crystal and polycrystalline samples.

title: Copy of: Structural Characterization of the Molecular Interactions in Concentrated Aqueous Azole Solutions:1,2,3-Triazole and 1,2,4-Triazole.

description: Azoles constitute an interesting class of heteroaromatic molecules because of the presence of two different structural patterns, such as p-electron networks and Hydrogen-bond donor and acceptor groups. Azoles are exposed to water solvent in a large number of biological system. The structure of aqueous solutions of azoles is of great interest: hydration is a complex phenomenon and the use of a combined approach is required to completely describe its structural and dynamical aspects. Spectroscopic and diffraction techniques provide qualitative information on intermolecular interactions: X-ray scattering is insensitive to H atoms. Neutron diffraction is sensitive to scattering from all constituent atoms, C, N, O, H. We would like to use this technique to examine the solvation and intermolecular interactions of the two concentrated aqueous azole solutions: 1,2,3-Triazole and 1,2,4-Triazole.

title: Mixtures of 124-Triazole and TBA Bromide with H2O as examples of ternary deep eutectic solvents. Their structure by theoretical and experimental investigation.

description: The effect of water on the nanostructure of deep eutectic solvents (DES) is an evidence that emerges from a large number of experimental reports: several groups have studied the nanostructure of DES/water mixtures to develop our understanding of how water interacts with the hydrogen bond networks within DESs. In this work we propose to measure in NIMROD instrument the solvation structure and the nature of the intermolecular interactions of 124Triazole-TBABr/water in amount (0.33 TBA-Br: 0.67 Triazole) /1H2O). The joint use of Neutron scattering experiments and DFT/Molecular Dynamics (MD) simulations represents a key opportunity to access spatial correlations in aqueous solutions at atomistic resolutions, thus enabling a profound understanding of the connection between the chemical properties, the resulting structural features and the bulk behavior.

title: Probing the effect of 3D-printing on perylene bisimide hydrogels

description: Perylene bisimides (PBIs), such as PBI-A, are low molecular weight gelators commonly used to form gels in water. Such supramolecular hydrogels, when blended with the non-gelling polymer PEO, are attractive as potential candidates for 3D printing. 3D printing offers a spatially controlled delivery of hydrogels which has potential applications in optoelectronics. Upon printing, these gels become significantly stiffer, suggesting a change in the packing or structure of the fibres. Therefore, we hope to investigate the structural changes both after a high shear has been applied and under compression to mimic the printing process, to understand these observations and give us the best performance in our gels.

title: Does the muon spin reach thermal equilibrium?

description: The usual assumption is that the muon's polarisation decays to zero in a relaxation measurement since the initial polarisation of 100% is much greater than the typical Boltzmann population. In high fields and low temperatures this is no longer a good approximation: the Brillouin function for B=5T and T=30mK gives P=49% assuming the muon reaches equilibrium with the spins in the sample which are causing the relaxation, and that these spins are also in thermal equilibrium. Reversing the field will change the sign of the effect and thus change the apparent amplitude of the relaxing signal.

title: Investigation of ion-selective binding equilibrium of phosphate in redox-polymeric films

description: Nutrients such as phosphorus (P) play an essential role as fertilizers in production of high crop yields. However, most of the P fertilizer is derived from imported phosphate rock, which are extracted from non-renewable deposits. State of the art removal and recovery systems face limitations in selectivity and regeneration, thus, there is a need to develop ion-selective systems for phosphorus recovery. We aim to investigate the behavior of selective redox-polymer interfaces in the presence of Phosphate (PO4x-) anions; in particular, we will address the following points: (i) does solvation of the anion and interface play a role in determining selectivity (e.g., solvent volume fraction entering in the film); (ii) how does polymer structure affect redox-mediated reversibility and solvation (e.g., what is the impact on solvation and ion ingression by adding/removing hydrophilic/hydrophobic moieties to the polymer structure). The flow-cell setup available at ISIS will be essential for screening of electrolytes with different phosphate concentration and pH, allowing to map the redox-polymer response to changes in electrolyte composition within the same experiment.

title: Calibration of quantitative multiphase analysis in copper – lead mixtures: powder and solid solution

description: Historical metallurgy and in particular bronze and other copper alloy metallurgy represents a research topic of strong importance in the study of the artistic and technological evolution of different civilizations. The current proposal represents the first phase of the CHNet-BRONZE project, and is part of a group of three, aiming at performing a basic calibration study starting from reference samples of known elemental, phase and microstructural composition. In this experiment we intend to evaluate the correct Uiso parameter for homogeneous, isotropic pure copper and pure lead phases by measuring metal powders of these two metals. We also wish to evaluate the peak broadening and Uiso effects related to the sample size so that the powder will be prepared within vanadium cans with different diameters.
