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: Eu3Bi2S4F4: uncovering mysteriously suppressed superconductivity using F–µ–F states

description: Cuprate superconductors have attracted considerable research interest over the past few decades due to their high transition temperatures which 
allows superconductivity to be accessed at liquid nitrogen temperatures. In light of this, there has been considerable effort in finding materials with similarities to cuprates which may also exhibit superconductivity at high temperatures. One of the promising families of materials are those formed of BiS2-layers, which tend to have a crystal structure analogous to cuprates. One of the most recently discovered compounds which exhibits superconductivity is Eu3Bi2S4F4, which consists of Eu3F4 layers which crystalize into a CaF2-like structure (where the fluoride ions are in a simple cubic arrangement), sandwiching bilayers of BiS2. Polycrystalline samples of this material shows a superconducting transition below about 1.5K, but this is not present in single crystal samples. This experiment aims to find out why, by observing the way in which the F--mu--F state changes with temperature for both single crystal and polycrystalline samples.

title: Transferability in Moonshine

description: Transferability of interatomic potentials in molecular simulation is a core assumption upon which most forcefields are built. Yet, forcefields are often parameterised against limited experimental structural data in the condensed phase, or commonly none at all. We propose to investigate the structure of the ternary “moonshine” mixture at four compositions, performing full isotopic substitution on each of the three components. This will yield a rich dataset by which recent advances in multi-configuration simulation analysis implemented in the Dissolve software can be fully explored, with a view to forming coherent workflows for similarly large parametric studies which are anticipated to form a significant part of the SANDALS-II programme.

title: Dataset to the publication Fracture behaviour of functionally graded bi-material interface produced by wire arc additive manufacturing

description: Dataset to Fracture behaviour of functionally graded bi-material interface produced by wire arc additive manufacturing, including FEM Analysis files, EBSD, Fracture Toughness, and Tensile Testing source data files. The data was obtained to describe the underlying deformation mechanisms at play during the mechanical deformation of a diluted interface layer. This diluted interface layer is formed between low alloy and stainless steels after cladding one onto the other after multi-material additive manufacturing. The data is the one measured through metallurgical and mechanical characterization procedures. Data set includes the output of several techniques, including: ABAQUS CAE - FEM data files with geometrical, boundary condition, mesh and load data, as well as summarized results for bi-material SENB specimensElectron Backscatter Diffraction (EBSD) - crystallographic information files, including files and graphs shown in the related publicationFractureToughness - pre-cracking, load-CMOD and derived plots for the fracture toughness analysis of conventional and bi-material SENB specimens,and TensileTesting - load-displacement values, as well as work-hardening values for data obtained under quasi-static tensile testing of bi-material and conventional specimens.

title: Noble gases as the ‘gold’ standard: liquid structure and fluid crossovers

description: From the beginning of disordered system diffraction, noble gases have served as the textbook example of a simple liquid structure. Yarnell’s liquid Argon data has been widely cited as the ideal structure of a liquid, and used to justify the use of the Lennard-Jones potential to qualitatively and quantitatively describe the structure of simple liquids. However, the dataset was smoothed by a non-disclosed procedure and the unsmoothed data have been lost. We therefore request 4 days of time on SANDALS to collect a dataset on liquid Krypton that can replace Yarnell's liquid Argon dataset as the gold standard of what a liquid S(Q) should look like. The time requested on SANDALS will also allow us to conduct an isothermal scan across various pressures at 135 K to establish whether, for a standard monoatomic fluid, the Frenkel line terminates on the vapour pressure curve as originally proposed in 2012 or continues to the triple point as proposed more recently by ourselves.

title: Deep Eutectic Solvents for Lignin solubilisation

description: Deep eutectic solvents (DES) are mixtures of two or more small molecules where strong intermolecular interactions lead to the formation of liquids at room temperatures. These solvents have wide applications from biomass extraction to syntheses, potentially replacing toxic and volatile organic solvents with liquids that can be made from more environmentally friendly components. The ratio of components in a DES affects its properties, including its ability to extract lignin as a solubilized polymeric material or to break it down into smaller components. Here we wish to understand how the ratio of components in a deep eutectic solvent based on xylitol:oxalic acid: ethylene glycol affects its interaction with a model species mimicking lignin to better understand how this solvent solubilizes lignin and the interactions which can enhance lignin extraction but lead either to preservation or break down of the polymer.

title: SANS probing of bacteria-silica-Hg interactions as encapsulation mechanism of mercury

description: High Hg levels, up to 4 ppm, in Amazonian fish indicate significant heavy metal (HM) pollution and stimulate research on bacterial bioremediation of these media. Simultaneous nanoparticles' aggregation and HM-bacterial uptake offer an unmatched test on how both phenomena can limit Hg-species' mobility. Since aggregation is a microstructural phenomenon dependent on time and pH, we propose contrast-matching and time-resolved SANS experiments on the SiO2 nanoparticles (NPs)-HgCl2-HM resistant bacteria system. We hypothesise that silica's aggregation in the presence of HM-resistant bacteria can encapsulate Hg, reducing its levels in the liquid phase. Measurements on 1 and 8 ppm Hg series will comprise ~60% and 100% D2O liquid buffers, pH ~7, pressure and temperature ambient conditions, totaling 4 time-resolved SANS experiments to probe the vector q range from ~0.004 to 0.3 Å^-1 at Larmor beamline. At pH~7, cationic Hg species predominate, raising our expectation to observe aggregates up to 157 nm. A ~60% D2O buffer matches the SLD of SiO2-NPs, which could help observe HgCl2-bacteria interactions. At 100% D2O, bacterial lipids display high squared contrast, providing the best conditions to probe silica–bacteria interactions. This proposal focuses on biosilica initial formation stages and could be important for the bioremediation of Amazonia media where Hg levels largely exceed the Brazilian law's threshold (0.5 Hg ppm).

title: Copy of Effect of the immobilisation of Pd single atoms and σ-H2-complex formation on the vibrational and rotational motions in MOF

description: Single-atom catalysts are the next frontier in catalysis research. When supported on metal-organic frameworks, single-atom catalysts do not only offer the benefits of their heterogenisation but also possibility for highly desirable tandem reactions. This proposal targets the determination of the single-atom catallysts' active centre’s local structure by probing the changes in the vibrational and rotational freedoms of motion of the MOF with and without Pd SACs added, as well as the specimens’ behaviour under hydrogen pressure. This will generate important information of the structure-catalytic performance relationships of this promising hydrogenation catalyst.

title: Exploration of crystal field level scheme of NdZnAl11O19

description: Exotic non-trivial magnetic behaviour has been recently reported in geometrically frustrated systems. In these systems, competing spin interactions leads to strong quantum fluctuations and prevent long range ordering (LRO) down to low temperatures. 2D triangular antiferromagnets (TAFM) is one of the prototypes to study frustration, as it has large degeneracy of ground states. Especially, rare-earth based TAFM having strong anisotropic magnetic interactions caused by spin orbit coupling and crystal electric field (CEF) effect, provides a platform for realising intriguing quantum phenomena. In determining the exotic magnetic ground state of these system, exchange and dipolar interactions, along with, crystal field scheme plays a vital role. Among these, crystal field is mainly responsible for governing the underlying physics. In respect to this, Nd based system is interesting to study. Nd3+ is a Kramer ion (J = 9/2) and having strong magnetic anisotropy. The 4I9/2 Nd3+ multiplets splits into five Kramer doublets due to CEF effect. To comprehend the magnetic properties and to quantitatively assess the magnetic interactions in NdZnAl11O19, it is essential to have knowledge about CEF level and single ion anisotropy.

title: Hydrogen in Steel Visualized by Energy-resolved Neutron Imaging

description: Visualizing hydrogen distributions via neutron imaging allows for quantification and a better interpretation of the processes involved in hydrogen embrittlement (HE)-assisted fatigue crack growth in austenitic and martensitic steels. Hydrogen is identified from the transmission intensities in both charged and uncharged samples. A gradient of hydrogen within the samples depending on outward diffusion of hydrogen with time is going to be considered. Once the detection limits on IMAT have been established, local hydrogen detection ahead of crack tips will be examined and correlated to fatigue crack growth rates (FCGRs). Samples strained and unstrained are considered for this purpose to understand the effect of straining, thus facilitating an understanding of the relationship between H concentration and FCGRs in steel. A major aspect of this methodical study is to utilize energy-resolved neutron imaging for detection of hydrogen in steel. Correlation of Bragg edge transmission at shorter neutron wavelengths with imaging beyond the Bragg edge cutoff of steel will allow optimizing hydrogen contrast. The outcome of this experiment will advance our mechanistic understanding of hydrogen transport, storage and embrittlement in structural materials
