title: Can muons measure F− ion diffusion? Exploring two simple test cases

description: Over the last decade muons have become established as an effective probe of ionic motion in a wide variety of materials. The primary motivation for
this work has been gaining greater understanding of materials intended to be used in electrochemical cells. There are further cations that may become commercially important in this area in the future, some of which are very promising for study with muons due to their nuclear magnetic moment (such
as Al3+), and others (e.g. Zn2+) where the natural abundance is far too low to make muon study feasible. Among the hitherto unexplored ions, F− sits somewhere in the middle ground in terms of feasibility: it has a sizeable moment but the well-known F–μ–F states have discouraged investigation.
Here we propose to study two prototypical F− ion conductors to investigate whether the muon signal can provide information about F− ion motion consistent with existing bulk results. Our intention is to open up a new area of study for muons and also gain a greater understanding of one way in which F–μ–F states can be perturbed.

title: Investigating temperature and magnetic field-dependent magnetic structures of square-net lattice compound LaMn2Ge2 by Single Crystal Neutron Diffraction

description: Magnetic topological insulators provide an important platform for realizing several exotic topological properties, such as anomalous Hall effect, anomalous Nernst effect, and topological Hall effect (THE), owing to the interplay between topology and magnetism. Antiferromagnetic (AFM) materials exhibit THE due to the presence of nontrivial spin structures. LaMn2Ge2 crystallizes in a tetragonal structure (I4/mmm) and exhibits ferromagnetic ordering at 325 K. We observed a large TH resistivity of ~4.5 μΩ-cm at room temperature. From magnetic studies, it is predicted that the large THE can be attributed to the noncollinear spin structure (conical) under applied magnetic fields. Therefore, a knowledge of the temperature and magnetic field dependent magnetic structures of LaMn2Ge2 by neutron diffraction is imperative to understand the origin of large TH resistivity. In addition, we observed large anomalous Hall conductivity due to the intrinsic Berry curvature contribution near to the Fermi level. These promising results suggest the possibility of spintronic devices based on antiferromagnets with tailored noncoplanar spin configurations.

title: Hygroscopic Coordination Polymer as “model-substance” for water molecule study

description: The ability to isolate a single molecule of water offers the unique opportunity of studying its fundamental quantum behaviour. Water exists as two distinct nuclear-spin isomers, para- and ortho-water. Understanding the mechanism of conversion between these two types of water is an important area of research. Moreover, the coherent quantum rotation dynamics of isolated water molecules could be exploited for future quantum technologies. We have synthesised the coordination polymer [Cu(pz)2·H2O]n which enables an easy and reversible way of absorbing and separating individual water molecules within its structure. We propose to study the quantum rotations, molecular vibrations and para-ortho transitions using MARI spectrometer. This study will allow to investigate the study of water molecule vibrations and quantum rotations when not involved in hydrogen bonds.

title: Probing anisole and guaiacol interactions with Bronsted acid sites within zeolites for catalytic biomass conversion

description: We propose to measure the vibrational spectra of the major lignin derivatives anisole and guaiacol in promising catalysts (zeolites HY, HBEA and HZSM5) to help understand lignin conversion processes into value-added fuels and chemicals. Lignin is abundant in biomass and can be upgraded over zeolite Brønsted acid sites (BASs). Various zeolite frameworks have differing BAS accessibilities and strengths. INS spectral band shifts relating to adsorption between the BASs and the model lignin methoxyl groups is of particular interest, having not yet been studied by INS. This will complete previous work studying hydroxyl to BAS interactions. INS in combination with DFT applying a VASP code will be used to locate anisole and guaiacol molecules within the zeolite pores, enable adsorption energy calculations and aid force field parametrisation for classical simulations for studying dynamics, all with the aim of aiding future catalytic design.

title: Charge and spin fluctuations at the collapse of the pseudogap in a cuprate superconductor

description: Understanding high-temperature superconductivity in cuprates remains a challenging problem. One approach is to characterise the evolution of the spin and charge excitations with doping and correlate these with other physical properties such as resistivity and heat capacity. We have had success in this regard using LET to demonstrate the existence of very-low-energy collective spin excitations for a sample with doping, p, greater than the critical doping where the so-called pseudogap disappears. Here we propose the measure at the critical doping of p*=0.19 where we have reason to think that both the spin and charge excitations will have the lowest characteristic energies. Our results may provide a framework to understand the strange metal (linear) behaviour observed in resistivity for this composition.

title: SANS identification of middle-phase microemulsion in-situ formed in porous media

description: The middle-phase microemulsion formed under equilibrium conditions has been widely reported. Previous works on middle-phase microemulsion mainly focused on the screening of formulations through phase behavior tests. It is still unclear whether the screened formulation at equilibrium conditions could be employed to generate microemulsions during the two-phase flow in porous media. This proposal will focus on the quantitative investigation of the microemulsion morphology and size parameters by SANs. The results are expected to provide direct evidence for in-situ micro-emulsification during surfactant flooding.

title: Scattering and refraction of cylindrical structures in SESANS

description: Refraction effects in neutron scattering experiments are often ignored. In this work we will explore a model system of cylindrical fibres where preliminary experiments in Delft have shown systems which exhibit both scattering and refraction. In this work we will explore a model system of aligned fibres where we can tilt the angle between the encoding access to change the contributions of scattering and refraction to the SESANS signal. Understanding of these types of system will be essential to model our data and apply this to similar systems.

title: Zein monolayers. Unusual liquid-liquid phase transition and interaction with (bio)surfactants

description: Zein is a major water-insoluble protein of corn seeds. Bearing some structural similarity with keratin proteins, zein gains popularity as a convenient model of skin/hair proteins in studies on possible effects of surfactants on human skin and hair. Zein monolayers display interesting compression behaviour, with an indication of an unusual liquid expanded-liquid expanded (LE-LE) type at surface pressure ~20 mN/m, which has not been discussed in the literature (previously interpreted as a collapse). In the course of the current proposal we plan to verify the hypothesis of the phase transition being related to formation of a comb-like structure within the zein monolayer. For this purpose the monolayer will be compressed and decompressed stepwise with NR measurements at several characteristic surface pressure values along the compression isotherm (5, 15, 20, 30, 40 and 48 mN/m). In the next step, the effect of a model anionic surfactant (SDS) and a biosurfactant (saponin) on the pre-compressed zein monolayer (30 mN/m) will be investigated to complement our recent Langmuir trough experiments. The latter clearly pointed to important differences between the synthetic and natural surfactants but their interpretation requires a more thorough understanding of the structural details accompanying the interaction which could be provided by the present proposal.

title: Inelastic neutron scattering on Prussian White as a function of the Na and water content

description: Prussian Blue Analogues (PBAs, AxM[M'(CN)6)]·zH2O) are a promising class of materials for sustainable positive battery electrodes, especially Prussian White (PW, Na2-xFe[Fe(CN)6]) due to its high theoretical capacity (160-170 mAh/g) and high operating potential (~3.2 V). However, the material exhibits many phase transitions as a function of the Na and water content followed by large volume changes. Water stabilizes the structure but is not good for battery applications leading to capacity fade upon electrochemical cycling. Thus, it must be removed or replaced with another compatible molecule. To successfully chemically modify PBAs and substitute water, a deeper fundamental understanding of the interactions between water and the PBA framework is needed. Inelastic neutron scattering (INS) is an ideal technique to study how neutral guest species, such as water, interact with A-site cations in PBAs. The INS experiment aims at developing a fundamental understanding of the structure-property relationships in PBAs and to pave the way for developing improved energy storage materials.
