title: Creating a double bilayer mimetic of the gram-negative bacterial envelope

description: The PqiABC complex has been implicated in phospholipid (PL) transport between the inner and outer membrane of gram-negative bacteria. This one complex spans the periplasm with components in both membranes, tethering them together. In a recent experiment, RB2220703, we proposed utilising this trans-envelope complex as a scaffold to create a planar double membrane architecture, providing a unique gram-negative envelope mimetic to probe envelope biology. Our Preliminary Neutron Reflectometry (NR) experiments confirmed re-constitution of the system but the distal bilayer remained liposomal and did not form a planar bilayar. However, in this configuration it allowed us to study PqiABC biology. We predicted PqiABC might be a proton motive force (PMF) driven PL pump based on structural homology. By altering the buffer pH, we were able to emulate the PMF across the liposomal membrane leading to a time dependent drop in the Scattering Length Density of the bilayer attached to the solid support. Suggestive of influx of hydrogenous material into the membrane, consistent with PMF driven PL transport. This proposal focuses on assessing conditions for rupturing the PqiAB proteoliposome to create a true double bilayer on the planar surface. This double bilayer configuration is required to properly assess changes within both membranes, a goal required to achieve our long term aim of using this double bilayer scaffold to study other envelope systems.

title: Assessment of Defects in Butt-welded W plates for nuclear fusion applications.

description: This experiment will provide what the authors believe will be the first set of neutron tomography on a 6 mm crack free tungsten weld. The experiment will greatly assist in further understanding how the microstructure of the tungsten plate changes due to welding and if there are any microstructural cracks. This work has the potential to influence decisions relating to the viability of tungsten as a candidate material for plasma-facing components in fusion reactors, and to pave the way for the manufacture of novel components for STEP.

title: Spin dynamics of a triangular-lattice quantum spin liquid candidate K2Co(SeO3)2

description: Quantum fluctuations stabilize novel collective phenomena in frustrated spin systems, such as quantum spin liquids (QSL) and magnetization plateaus. Here we propose to use inelastic neutron scattering (INS) to investigate the spin dynamics of a triangular-lattice quantum spin liquid candidate K2Co(SeO3)2. This compound exhibits strong magnetic frustration and field-induced magnetization plateaus, but no long-range order is found down to 0.35 K at zero field. Unlike many QSL candidates, K2Co(SeO3)2 shows no signature of structural disorders which is known to complicate the interpretation of the INS data, and it has an easy-axis type anisotropy. We will study the magnetic excitations in both the potential QSL phase at zero field and the field-induced plateau phase. Our results would uncover the exotic spin dynamics of a QSL material without complexities due to structural disorder.

title: Self-assembly and structural changes in nanorods formed by anthracene and chlorophyll-based derivatives

description: We propose a SANS experiment to (i) gain structural insight on nanotubes formed by anthracene derivatives and (ii) using time-resolved experiments, investigate structural changes in fibres formed by chlorophyll-based derivatives. This builds upon recent beamtime results from LARMOR (RB2220130). We have already obtained data on these systems using SAXS (KEK, Japan) and atomic force microscopy, but SAXS only attains a single, complex contrast profile and microscopy only observes the product out of solution. SANS is required to facilitate the global fitting of multiply contrasted datasets necessary to build up a detailed structural picture of these complex assemblies. While the experiment could run on any TS2 beamline, SANS2D is preferred, as these are dilute and relatively weakly scattering systems. The lower background of SANS2D will allow feature-filled scattering at mid-high Q to be better visualised.

title: Probing Interfacial Magnetism and Magnetic Coupling Phenomena in Antiferromagnet - Nanocrystalline Topological Insulator Heterostructures

description: Topological electronics makes use of novel quantum degrees of freedom, as they are encountered in topological insulators (TIs). One of the most remarkable properties of a TI is the dissipationless carrier transport through its surface states. In magnetically doped TIs, the quantum anomalous Hall effect (QAHE) was observed; a zero-field version of the ordinary quantum Hall effect. However, due to defects associated with the doping, the useful temperature range is rather small. Proximity induced magnetisation is a promising method to create ferromagnetic order in TI. Using an antiferromagnet as magnetic adlayer reduces stray fields that can interfere with the QAH states. We recently discovered that diffusion of magnetic constituents in heterostructures of Mn-based magnetic materials and TI can mimic the elusive proximity induced magnetisation effect at the interface. To address this problem, we propose to utilise NiO/nanocrystalline Bi2Te3-heterostructures grown using sputtering to substantially reduce diffusion and to achieve high-quality interfaces. This should facilitate the observation of proximity induced magnetisation using polarised neutron reflectometry.

title: Unraveling processed cheese structure: Effect of calcium sequestering salts on casein micelle suspensions

description: One of the key routes to attain functionality in processed and analogue cheese productions is via the addition of calcium sequestering salts (CSS). CSS are needed to disrupt the scaffold of primary casein particles and calcium phosphate nanoclusters that is naturally present in casein micelles, and remains present in rennet casein or cheese. We have characterized our proposed system (see section 3) of micellar casein with different CSS through various means. The combination of SANS and spin-echo SANS (SE-SANS) will enable elucidating the underlying structure and interactions in across a range of smaller and larger length scales not typically achievable by other means. We want to perform SANS and SE-SANS measurements on micellar casein suspensions containing different CSS, i.e., sodium salts of citrate, pyrophosphate and hexametaphosphate.

title: Spin correlations in the ground state of NaSmMn2Ti4O12: A possible transition from high-temperature long-range ordered to low-temperature short-range correlated states

description: A new family of perovskite titanates NaRMn2Ti4O12 with R = Sm, Eu, Gd, Dy, Ho, Y has been recently obtained using high pressure synthesis. The members of the family crystallise into columnar quadruple-perovskite structure and show a long range magnetic order below 11-13K. Surprisingly, our previous neutron diffraction study revealed a second transition in Dy compound from high-temperature (T6K) ordered to low-temperature (T&lt;6K) short-range correlated magnetic ground state. This is a very unusual transition, the nature of which is currently unclear. The aim of the present neutron diffraction experiment is to probe the long-range versus short range correlated ground state in the Sm perovskite which also shows two magnetic transitions on macroscopic measurements.

title: Characterisation of PAPEO-b-PAEMA based micelles using small angle neutron scattering

description: Due to the controlled micellisation and their role as both templating and functionalising agent, PolyIon Complex (PIC) micelles are a valuable asset for the synthesis of functionalised ordered mesoporous materials. They are assembled through the electrostatic complexation between a charged double hydrophilic block copolymer (DHBC) with an oppositely charged polyelectrolyte. Physico-chemical parameters, such as pH variation, can control their micellisation properties, which is of prime importance in devising of porous materials. Primarily, during the porous material synthesis, the silica precursor is allowed to condense over the PIC micelles acting as the template and once the condensation is completed the micelles are disassembled via pH change, revealing the porosity. We developed a new DHBC (RAFT polymerisation), P(APEO)m-b-P(AEMA)n, made of a poly(ethyleneoxidepolyacrylate) (PAPEO) neutral block and a positively charged aminoethyl methacrylate block (PAEMA). The electrostatic complexation of PAPEO-b-PAEMA, with negatively-charged poly-acrylic acid (PAA) can lead to micelle formation.
Each DHBC/counter-ion couple needs a specific charge ratio (CR) between negative and positive charges to obtain well-defined micelles. CR will depend on the DP of the PAEMA block and the molecular weight of PAA, which may also influence the size and shape of the micelles. Knowing the characteristics of these novel micelles is mandatory before using them for porous material synthesis.

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.
