title: Measurement of the polarized 3He neutron absorption cross section

description: A three-body force is a force that is not present in a system of two objects but manifests in a three-body system, that is to say the two body forces are insufficient to describe the system. For neutron-rich (exotic) nuclei the stability becomes increasing critical to the three-body nuclear (3N) forces. Also calculations of the deuteron-tritium fusion reaction, intensively studied for power generation, require 3N forces. Although models for the 3N forces exist and give a rough estimate of the relative sizes and spin dependence of three- and higher-body effects compared to two-nucleon forces, more precise experimental data on systems with few nucleons is needed to determine the relative strengths of these forces. To better constrain the spin-dependent parts of the 3N force, data are required on the spin-dependent scattering of three- and four-body systems with precision at the sub-percent level. We have been working to determine the n-3He incoherent scattering cross section in experiments at FRM2 and upcoming at SNS. These values however are dependent on the polarized 3He neutron absorption cross section, σp, which has only been weakly experimentally or theoretically bound, further knowledge of this cross section in itself adds to the experimental constraints on theory of three-body forces. In order to determine σp absolutely we propose to measure the transmission of a polarized 3He cell while performing a precision NMR measurement of absolute 3He polarization.

title: Pressure-Induced Structural Transitions in Zeolitic Imidazolate Frameworks

description: The structural evolution of ZIFs as a function of CO2 and N2 adsorption/desorption will be investigated using in situ neutron total scattering. ZIFs exhibit conformational and phase transitions that increase the uptake of guest molecules. Phase-to-phase transformations due to pressure and gate-opening (adsorption) and -closing (desorption) have been observed in the short- and long-range structure of ZIF-8 and ZIF-7 at moderate and high pressures. In this study, we will follow the structural transitions of the two ZIFs at different pressures (1.35 – 10 bar) of CO2, N2, and an equimolar CO2/N2 mixture. By using total scattering, we aim to elucidate the interplay between local adsorption phenomena and long-range structure. The mechanistic information obtained from this study will enable the design and development of more effective MOFs for gas adsorption. We also hope to isolate the ideal process conditions for trapping guest molecules and selective adsorption, which are essential to carbon capture, utilisation, and storage technologies.

title: Autonomous Formulation of Latex Coatings via Concurrent SANS and SAXS at RAL

description: Liquid formulations for industrial applications (paints, shampoos, etc.) contain 10s-100s of components to balance complex design requirements in response to product needs, environmental requirements, and other driving forces. In these mixtures, small perturbations to composition can cause drastic changes in performance due to changes in the phase behavior. Despite the availability of X-ray and neutron scattering techniques for quantifying liquid-liquid phase behavior, the large number of components makes mapping phase space challenging.
Driven by the nSoft industrial consortium, we have developed an autonomous formulation laboratory (AFL) which prepares liquid mixtures from stock solutions using a pipetting robot and performs small-angle scattering (SANS or SAXS) measurements. We have developed AI approaches that automatically analyze data and automatically choose the next solution composition. 
We propose to use concurrent SAXS (Diamond I22) and SANS (LARMOR) to probe the desired aggregation of TiO2 pigment with polymeric latex binders. These composite particles are required to achieve the desired hiding properties of the coating at an appliable viscosity while reducing the amount of TiO2 pigment used in the formulation. Using the AFL, we will autonomously probe a series of different pigment and binder chemistries at various solution conditions (pH, salinity, etc) to determine the effect these variables have on the self assembly of the pigment-latex aggregates.

title: Quantum spin liquids in 1:2 cation ordered perovskites

description: ABO3 perovskites have the ability to form different cation ordered superstructures that may be used to explore quantum magnetic properties such as quantum spin liquid (QSL) formation. Honeycomb lattices of QSL interest can be made by alternating 1:2 layers of non-magnetic:magnetic ions in the cubic-[111] direction giving A3BB’2O9 materials with the trigonal 3C1:2 (Ba3SrTa2O9-type) structure. We have prepared 3C1:2-Ba3MRu2O9 materials (M = Ca, Mg) at high pressure. Magnetic susceptibility measurements demonstrate paramagnetic behaviour with no apparent spin transitions down to 2 K, consistent with QSL behaviour. PND data are needed to provide a definite confirmation of the structure and absence of long range spin order at low T.

title: Magneto-elastic enhancement of sublattice interactions in RMn7O12

description: The quadruple perovskite manganites provide a fruitful playground to explore the interplay between charge, orbital and spin degrees of freedom on multiple sublattices, producing exotic phases of fundamental scientific and technological interest. Across the monoclinic A3+Mn7O12 family, competing descriptions of magnetic order have been put forward and ascribed to the same characteristic magnetic intensities. Such discrepancies have emerged due to an inherent difficulty in differentiating competing models against magnetic diffraction alone. Using symmetry arguments we have established that a strong magneto-elastic coupling scheme, as evidenced in the lattice parameters, can support only one of the proposed magnetic models.We propose a neutron powder diffraction experiment on PrMn7O12 to confirm our hypothesis. Secondly, we aim to solve the ground state magnetic structure, likely elucidating the role of orbital instabilities in mediating magnetism across the wider family.

title: Characterisation of the protein corona structure in organ selective lipid nanoparticles

description: Since their success as the delivery technology in the Covid-19 mRNA vaccines, lipid nanoparticles (LNPs) are
revolutionizing nanomedicine. Key challenges in developing new technologies include increasing their ability to target specific organs and cells in the body. In biological environments, proteins present in solution adhere to the lipid nanoparticle surface and can impact the performance of LNP nanomedicines. However, there is still limited knowledge on how these adhered proteins - also known as the protein corona - differ between LNPs with different structures and lipid compositions. By understanding the differences in protein corona structure in LNPs known to show specific organ selectivity, we aim to quantify develop tools that will longer term enable us to engineer these interactions and design the next generation of LNP nanomedicines.

title: Dynamic SANS study of vanish blanching

description: Paintings are artistic expression in soft materials. Their component polymers, dispersions and emulsions are well-known to soft matter physics and ideally investigated by small-angle neutron scattering (SANS). Working with museum partners, we aim to use SANS to characterize and understand blanching, a leading open challenge in modern conservation. Blanching involves irreversible damage to a painting by exposure to moisture, causing the varnish or paint to become opaque. The structural changes are thought to result from the growth of nanoscopic pores that scatter visible light. The appearance and evolution of these pores is suggestive of spinodal decomposition, working to minimise the interfacial area between a hydrophobic varnish polymer and water infiltrating into its initially invisible pores. SANS is ideally suited to non-invasively characterise this process in real and mock-up samples, providing key observations to feed into models of polymer-solvent interactions to predict blanching damage accumulation. It can also reveal changes in varnish structure before blanching becomes visible, e.g. for mapping out damage risk to inform conservation decisions. In this first proposal of an ISIS Development PhD Studentship on “Art, soft matter and SANS”, we will use SANS to investigate mastic varnish samples prepared and damaged by water immersion ex-situ, vanish samples damaged in-situ by immersion in D2O on the beamline, and mock-up blanched samples provided by gallery partners.

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: What is the solution structure of Ce in different oxidation states? An in-situ electrochemical and neutron diffraction study in water

description: The aqueous coordination chemistry of the f-block is underdeveloped in comparison to the transition metals, but important emerging technologies (e.g batteries) or closed loop recycling strategies that rely on lanthanides do not have sufficient structural or thermodynamic grounding. In the proposal we aim to examine the structure of Ce(III) nitrate and electrochemically oxidise to Ce(IV) nitrate to directly compare the structures (e.g. inner vs outer sphere nitrate coordination; coordination number) and formation constants for any equilibria that may be formed. This will use a newly developed electrochemical cell so all measurements and the bulk electrolysis steps are conducted inside the instrument. The results will be augmented by EXAFS data measured on B18 at Diamond.

title: Investigation of the antiferromagnetic order in superconducting nickelates

description: Recently, superconductivity has been surprisingly reported at 15 K in Sr-doped NdNiO2 suggesting the existence of a new family of high-temperature superconductors. The structure of this nickel oxide consists in a stacking of NiO2 layers separated by rare-earth spacer layer, stabilizing the unusual Ni1+ oxidation state, corresponding to 3d9 electronic configuration, similarly to the cuprates. Our previous experiment on WISH @ ISIS, brought evidence for a AF order with a propagation vector of q_AF=(1/2,1/2,0), in two samples, a pure and 5% Sr-doped (Nd,Sr)NiO2 that could be at the origin of magnetic fluctuations playing a key role in the emergence of superconductivity. We first proposed to establish if this magnetic order is related to Nd or Ni atoms by studying LaNiO2 analogue. Then we proposed to precisely study the temperature dependence of the magnetic order and its possible connection to the low temperature upturn reported in resistivity in the (Nd1-xSrx)NiO2 with x=0,0.05. 
WISH beamline is perfectly suited for magnetic structure determination and temperature evolution study. The study will be done at five chosen temperatures in the range 1-100K for the three samples, (Nd1-xSrx)NiO2 with x=0,0.05 and LaNiO2. Based on the previous experiment characteristics, we expect to count 4h per temperature. We thus ask for 3 days on the WISH high-resolution cold-neutron powder diffractometer to carry out our investigations
