title: Coexistence of Magnetism and Superconductivity in Topologically Nontrivial Heterostructures

description: One of the foremost challenges in the development of quantum computing is the development of computing platforms which are "fault tolerant", in the sense that physical errors in the system do not affect the result of a computation. It has long been theorized that topological superconductors may form the basis of such a system, but the realization has proven extremely challenging. In particular, hybrid devices comprised of a high spin-orbit semiconductor with time-reversal symmetry breaking such as a magnetic topological insulator and a conventional superconductor are though to be an excellent candidate for a topological superconductor with the right properties at zero magnetic field. Here, we probe the magnetic depth profile of one such system exhibiting interfacial superconductivity in proximity to a magnetic topological insulator to verify that the target criteria are satisfied.

title: Investigating the Effects of Vitamin E Acetate on the Structure of Exogenous Pulmonary Surfactants by Neutron Reflectometry

description: The usage of electronic-cigarettes and vapes has lead to a huge wave of people being diagnose with a respiratory distress illness known as e-cigarette or vaping use-associated lung injury (EVALI). Data has shown that a compound known as vitamin E acetate has been found in fluid extracted from the lungs of these patients. This compound is used as a diluent in many cannabis-related vaping products. It is hypothesized that this compound interacts with the pulmonary surfactant (PS) in the human lungs and compromises the biophysical properties therefore affecting the breathing process of those affected. Through investigating various structural characteristics of PS with and without the toxin using neutron reflectometry, it will bring us one step close to solving the mystery behind the mechanism of EVALI and how exactly the lungs of those affected are compromised.

title: High-field magnetic states of a novel distorted triangular antiferromagnet

description: The magnetic phase diagram of distorted triangular lattice antiferromagnets is often populated by exotic quantum states, e.g. two-dimensional incommensurate spin-density waves and frustration-induced magnetization plateaux. Theoretical predictions of spin-density waves in triangular systems exist, but experimental realizations still lack. Plateau states are quite rare, or inaccessible due to the high magnetic field required. The novel triangular lattice system Cs2CoBr4 hosts both these field-induced states and two additional unknown phases, all accessible at convenient magnetic fields &lt; 6 T. Our goal is to determine the magnetic structure of the unknown states and complete our understanding of this exotic quantum magnet. The experiment will also expand our knowledge of ordered states supported by frustrated antiferromagnets on triangular lattices close to saturation.

title: Temperature Dependence of Diffuse Scattering in the New Pyrochlore Magnet Ce2Hf2O7

description: Magnetic materials displaying quantum spin liquid (QSL) ground states are of great topical interest due to the exotic nature of their excitations and emergent properties at low temperatures. Ce2Zr2O7 and Ce2Sn2O7 are cubic pyrochlore QSL candidates that have attracted much recent attention, offering the possibility for novel QSL phases at low temperature due to the “dipolar octupolar” (DO) character of the Ce3+ pseudospins. Here we are proposing to probe the magnetic correlations from a powder sample of Ce2Hf2O7, a sister Ce3+-based pyrochlore magnet to those expressed in the dipolar-octupolar QSL candidates Ce2Zr2O7 and Ce2Sn2O7. The proposed experiment will have sensitivity to both dipolar and octupolar correlations, which will be crucial in developing an understanding of Ce2Hf2O7’s magnetic ground state.

title: Viscosity anomaly and transient immiscibility in liquid Ga2Te3 promising for high-temperature memory applications

description: Emerging brain-inspired computing needs phase-change materials (PCMs) of the next generation with lower energy consumption and wider temperature range. Ga2Te3 has higher melting and crystallization temperatures compared to flagship PCMs and simultaneously a low switching power and fast switching rate. Fast transformation rate in PCMs at nanosecond scale is directly related to a low viscosity in the liquid state. Ga2Te3 melt shows a highly unusual anomaly, a sudden viscosity increase just above the melting point. Our preliminary HE-XRD data suggest transient liquid-liquid immiscibility is the origin of this anomaly. A detailed response can be obtained using NIMROD experiment over a wide Q-range starting from 0.01 Å-1. EPSR modeling using large simulation boxes will complete the experiment providing deep insight into atomic structure at the local and mesoscopic scale.

title: Using an epithelial model membrane to investigate polyphenol-lipid interactions with neutron reflectometry

description: This study forms part of a current 4-year PhD studentship to develop an epithelial apical plasma membrane model to investigate the role the lipid composition has on biological activity and drug/nutrient absorption. The current proposal is crucial to provide data to complete the data series for the lipid-polyphenol interaction studies in conjunction with other complimentary techniques (QCM-D and ATR-FTIR) required for a high impact publication in a top tier journal. This is the final opportunity for this PhD project to gather neutron data on model membrane systems and to structurally characterise interaction with polyphenol neutraceutical compounds. This is vital for robust completion of the PhD project.

title: Characterization of Solid-State Phase Morphology in Amorphous Solid Dispersions

description: A common property among drug candidates is poor water solubility, which limits their uptake in the body. In response, an amorphous solid dispersion (ASD) is a pharmaceutical formulation that uses a polymer matrix to kinetically trap amorphous phases of the active pharmaceutical ingredient (API) to improve its solubility and efficacy. They can be formulated as pills or implants, and their dissolution profile is directly related to the morphology of the API-rich phase which is sensitive to both composition and processing conditions of the blends. In this work, we will use SESANS to characterize the degree of phase separation in these materials, understand the mechanism by which the polymer traps amorphous forms of the API, and answer the question: how does ASD phase morphology change as a function of active phase concentration and choice of polymer matrix?

title: Evolution of droplet size in nonaqueous emulsions using time-resolved, time-of-flight SESANS

description: Emulsions consist of two immiscible fluids (most often water and oil), where one can be dispersed in the other. In addition to mixing water and oil, there is considerable interest in understanding emulsification of immiscible nonaqueous fluids (oil-in-oil emulsions), which have many applications. Techniques that can measure the droplet size over relevant length scales are required. Spin-echo SANS (SESANS) is a scattering technique suited for this purpose, due to its sensitivity to large (µm) length scales and its tolerance of large amounts of scattering. In this experiment, time-resolved measurements will be performed that will reveal the evolution of the particle size of nonaqueous emulsion droplets, using time-of-flight SESANS, a technique available on the Larmor instrument at ISIS that can measure scattering over a wide range of length scales simultaneously.

title: NR Study of Helper Lipid Effect on Interaction between Lipid Nanoparticles and a Model Lipid Bilayer Mimicking Endosome Membrane

description: LNP has become one of the hottest topics during the ongoing pandemic of COVID-19 due to their application as the gene delivery vector for both the Pfizer–BioNTech and Moderna mRNA vaccines. LNPs are internalised by the cells through endocytosis and the endosomal escape process releases the payloads: this process is often the major bottleneck in achieving high cell transfections. Neutron reflection is particularly powerful to study the interaction between the LNPs and a model supported lipid bilayer (SLB) mimicking an endosome membrane. The aim of this study is to determine how different lipids help mediate the interaction of LNPs with lipid membrane bilayer, mimicking an important step in endocytosis, as a function of crucial factors such as temperature and solution pH.

title: Investigating the fate of atmospherically relevant organosulfate monolayers at the air-water interface

description: The proposal will use neutron reflectometry to investigate the oxidation of atmospherically relevant organosulfate films at the air-water interface by gaseous ozone. Organosulfate compounds constitute a large fraction of aerosol organic material and there is a significant lack of understanding regarding their transformation and fate in the atmosphere. Such compounds are surface active and can influence cloud droplet formation thus impacting the climate. The goal is to determine the oxidation kinetics of organosulfate films and to determine if any material remains at the air-water interface. Additionally, the influence of the chemical structure of the starting material (number of double bonds) on the oxidation kinetics will be determined. Overall, the study will inform on the fate of atmospherically relevant organosulfates to oxidation by gaseous ozone.

title: Do cardiolipins play a role for the mode of action of antimicrobial peptides? A study using free floating lipid model membranes

description: Antimicrobial peptides (AMPs), also called host defense peptides, are part of the innate immune system of essentially all species, from bacteria themselves to mammals to protect against bacterial pathogens. Although the exact microscopic mechanism(s) is still debated, this chemical structure allows them to target bacterial cell membranes which have net negative charge, selectively. One hypotheses of the mode of action is that AMPs interacts with cardiolipins (CL), and important anionic lipid present in bacterial membranes where its function is essential for bacterial pathogenesis and survival in various environments. In this project we set out to investigate whether the distribution of CL is disturbed by AMPs using neutron reflectometry. The obtained results will guide ongoing strategies in designing new effective peptide based antibiotics against resistant bacterial strains.

title: Ionic diffusion via oxygen vacancies and interstitial positions in layered Ruddlesden-Popper nickelates: A high-temperature study

description: Rare-earth nickelates Ln2NiO4+δ (Ln = La, Pr, Nd) with perovskite-related layered Ruddlesden-Popper (RP) structure are promising mixed ionic-electronic conductors (MIEC) for high-temperature electrochemical applications such as dense MIEC membranes for oxygen separation and oxygen electrodes for solid oxide fuel/electrolysis cells. The objective of the proposed study is to provide an insight on the changes in oxygen diffusion mechanism on a gradual transition from oxygen excess to oxygen deficiency in the RP structure occurring on substitution of lanthanum by strontium in La2-xSrxNiO4+δ. To this end, the neutron diffraction patterns of three compositions (x = 0, 1.0 and 1.6) will be collected at room temperature, 700°C and 900°C and analyzed by a combination of Rietveld analysis and maximum-entropy method to reveal the dominating pathway of oxygen-ion diffusion.
