title: Correlating the surfactant-rich interparticle volume to the water absorption and rheological behaviour in a model waterborne coating

description: Waterborne coatings present a viable alternative to traditional solventborne coatings by reducing the emissions of harmful volatile organic compounds (VOCs). However, their development is currently hindered by the complex heterogeneous structures formed during film formation. This research focuses on understanding impact of the coating’s structure on the water transport. Previous ISIS experiments revealed that absorbed water creates a complex structure in the material characterized by two primary length scales. We relate the first characteristic dimension to surfactant clumps located at the interstitial voids between the particles, while the second is associated to water channels located at the interparticle interphase. In this proposal, we aim to validate and refine our model by systematically modifying the properties of the interparticle interphase through the addition of cosolvents and altering the size of voids available to the surfactant by varying the particle size.

title: Evaluation of residual stress relaxation in electron-beam welded stainless steel under in-situ cyclic loading using Bragg edge imaging

description: Welding processes are known to generate residual stresses which might affect the fatigue performance of components. Residual stresses interact with the applied load, and studies have shown that when the static or cyclic yield strength is exceeded, local plastic deformation might occur and subsequently reduce the residual stresses. The omission of stress relaxation information in power plant component assessment procedures can lead to over-conservative life-time predictions of power plant components. More accurate information of residual stress relaxation will lead to more realistic lifetime predictions and possible lifetime extension. We propose an in-situ cyclic test in conjunction with Bragg edge imaging on IMAT which will allow mapping residual strain profiles in one exposure, thus enabling tracking the evolution of residual strains at different regions across the weld.

title: Low-temperature instabilities in the multiorbital magnet CuCr2Se4

description: Competing valence distributions across the interpenetrating sublattices of spinel materials have long been subject to debate. While many such compounds, like CuCr2Se4, are simple (room temperature) ferromagnets, we were recently able to observe multiple low-temperature transitions by local magnetic probes. Moreover, using neutron powder diffraction, we discovered that at least one of the transitions in the sister compound CuCr2S4 is associated with the formation of a commensurate superstructure. However, it remains unclear which magnetic structure (conical or spin density wave) describes the observed superstructure. To understand the mechanisms of these transitions, we need to clarify whether (and how) they arise from the frustration of charge/valence and magnetic degrees of freedom on the spinel lattice. Using low-temperature high-resolution neutron single crystal diffraction, we propose to track the evolution of the magnetic structure of a CuCr2Se4 crystal.

title: thermal-to-epithermal study of calcium hydroxide, Ca(OH)2.

description: In our recent study of borated concrete materials on VESUVIO, we have discovered that the local chemcial dynamics of hydrogen and oxygen in these materials is correlated to the molar ratio of B2O3 to Ca(OH)2. We have previosuly performed a broadband neutron study of boron oxide, B2O3. Our analysis of neutron Compton scattering (NCS), transmission (NT) and diffraction data (ND) is, however, slightly hampered by the lack of information about the structure and dynamics of Ca(OH)2. Here, we propose to measure, NT, NCS, and ND concurrently on VESUVIO to bridge this gap.

title: The impact of high pressure on the vibrational spectrum of molecular organic semiconductors

description: The van der Waals nature of organic semiconductors (OSCs) offers low cost processing while intermolecular vibrations affect their charge transport properties. By using inelastic neutron scattering and terahertz spectroscopy, combined with quantum mechanical simulations, we have characterized for the first time the full-spectrum of low-frequency motions in several OSCs, identifying the long axis sliding motion as the killer phonon mode. Within this framework, the aim of this proposal is to push our study further and investigate the impact of pressure on the vibrational spectrum present in these soft materials. This will allow us to 1) understand the impact of pressure on the thermal disorder in OSCs, 2) elucidate how the killer phonon modes are hampered as a function of molecular design and packing, 3) test if there is a critical pressure value at which killer phonon modes are affected and, 4) develop potential pressure/strain strategies to improve transport properties in these soft materials.

title: Crystal structures and thermal expansion of the high pressure phases of ammonium bicarbonate, (ND4)DCO3

description: In an earlier high-pressure survey of the P,T phase diagram of deuterated ammonium bicarbonate, we observed changes in the neutron powder diffraction patterns that are consistent with a number of polymorphic phase changes. However, data suitable for unambiguous indexing of the powder patterns was not collected and there is a large degree of uncertainty as to whether some of the datasets truly reflect different phases or simply highly anisotropic peaks shifts. Our goal is to cryogenically recover the two high pressure phases (phases II and III) observed at room temperature using the multi-anvil press SAPHiR at the FRM II, Germany, and collect the highest-resolution neutron powder patterns using HRPD, such that we may index new phases with confidence, solve their structures, and observe their behaviour upon warming.

title: Effect of hydrothermal aging on the proton distribution in Cu-CHA zeolite catalysts

description: Cu-CHA zeolites are excellent catalysts for the removal of NOx from diesel vehicle exhaust gases, through the NH3-SCR reaction. Even if they are outperforming other Cu-zeolites for their activity and hydrothermal stability, the harsh conditions of temperature and presence of water vapour in the exhaust can cause the phenomenon called dealumination, which removes Al atoms from the framework and causes deactivation. We want to study the effect of hydrothermal ageing on the distribution of OH groups in Cu-CHA by means of Inelastic Neutron Scattering on the high resolution instrument TOSCA, to understand the main parameters affecting stability.

title: The structure of compressed D2 and location of its Frenkel Line

description: Recent advances in instrumentation now render it feasible to access a factor of 7 higher pressures than previously available for structural measurements on light molecules such as deuterium. We aim to provide the first experimental determination of the structure of compressed supercritical deuterium at increasing pressures approaching the melting line, to determine whether a Frenkel line exists in deuterium and if it does, what its precise location is on the phase diagram. This will be a first step in a series of studies of quantum effects on the fluid structure of hydrogen isotopes.

title: Topochemically Reduced Iridium oxide phases

description: There is growing interest in the topochemical reduction of transition metal oxides to form oxyhydride (containing both O2- and H- anions) or oxide-ion deficient materials, as these phases can exhibit electronic and magnetic behaviour which is strikingly different from the corresponding all-oxide starting materials. Following this synthesis strategy we have prepared a series of reduced/anion-exchanged phases from iridium-containing complex oxides: LaxSr4-xCoIrO8 (x = 0, 0.5, 1, 2) Ruddlesden-Popper phases have been converted to the corresponding LaxSr4-xCoIrO6H¬y phases; LaxSr2CoIrO6 (x = 0, 1) double-perovskite oxides have been converted to the corresponding LaxSr2CoIrO4 and LaxSr2CoIrO4Hy phases, and hexagonal Ba3CoIr2O9 has been converted to Ba3CoIr2O6Hy and Ba3CoIr2O8Hy. We propose to collect high resolution neutron diffraction data from these reduced materials to determine their crystal structures (especially the location of the hydride ions) and also their low-temperature magnetic structures.

title: The interaction of 5-Hydroxymethyl Furfural (HMF) on a biochar catalyst after the addition of an oxidant and co-catalyst - TOSCA

description: The oxidation of 5-hydroxymethyl furfural (HMF) can lead to the production of poly(ethylene 2,5-furandicarboxylate) (PEF) – a polymer that could replace the petroleum based polyethylene terephthalate (PET). In this context, we have developed a naturally iron-containing biochar (BCR) catalyst from palm oil empty fruit bunch which we found to catalyse the reaction under very mild conditions by use of an organic peroxide and radical mediator co-catalyst. We have recently probed the mechanism of the catalysis to understand the molecular-scale interaction of the HMF with the BCR using INS and results show that the C-H and O-H of bending modes of HMF are observed differently when the radical initiator TEMPO as the co-catalyst was added. We now wish to probe the mechanism of the catalysis when both the co-catalyst and the oxidant are added. For HMF oxidation such mechanistic detail is missing in the literature and for our material such information will allow us to improve and optimise the catalyst further. BCR is very difficult to study by conventional vibrational spectroscopy, as the infrared spectrum is dominated by the residual oxygen functionalities and the Raman by carbon modes. INS enables the complete spectral range to be examined, and parallel proposals for MAPS (for the region above 2500 cm-1) and TOSCA (for the region below 2500 cm-1) will be submitted.
