title: Magnetic depth profiling of Fe3O4/SrTiO3 heterostructures to reveal dynamics of interfacial switching

description: Controlling the oxide interfaces is the key towards controlling the switching phenomenon and thus realizing functional devices. We found that oxide substrates can take an active part in the redox process at the interface and may be even used to tune properties. Hence, our next goal is to real-time monitor the redox reactions at the interface when the properties or "iron oxide phases" of the interfaces and the films are tuned.
We have characterized our samples using different lab techniques, e.g. XRR, XRD, SQUID and GISAXS, or using large scale X-ray facilities, e.g. HAXPES and XMCD. Using SQUID, we observe the disappearance of Verwey transition, the characteristic temperature for Fe3O4, when applying a positive voltage. This indicates a perturbation of oxygen content in the Fe3O4 phase and possible switching to the insulator gamma-Fe2O3 phase at the interface. Thus, our next step is to monitor in-situ the magnetic depth profiling when applied electric field using polarized neutron reflectivity in order to real-time monitor the thickness and the composition of the intralayer.

title: Phonon anomalies and structural instabilities in TbScO3 (HRPD)

description: Distorted perovskite TbScO3 is a particularly interesting lanthanide scandate, exhibiting a dramatic flexoelectric effect, along with the common features of the wider family of lanthanide scandates. Accurate knowledge of its structure and dynamics is of particular importance, for example due to its use as a substrate for epitaxial growth of high-quality perovskite thin films. However, the structure and dynamics of this material at low temperatures are not properly understood. We plan to investigate these by combining phonon studies with powder and single crystal neutron diffraction. Powder diffraction on HRPD and single crystal diffraction on SXD will be used to study structural models and characterise subtle distortions of this material. Phonon spectrometry on MERLIN – preceded by careful phonon characterization using CASTEP with Horace and the Euphonic package – will be used to clarify discrepancies between phonon modes allowed by symmetry and those previously experimentally observed.

title: Adsorption mechanism of crude tall oil (CTO) on supported transition metals catalysts to better understand the production of renewable fuels through hydrodeoxygenation

description: Waste and co-products from the Kraft paper and cellulose production process have the potential to be transformed into renewable fuels through heterogeneous catalytic hydrodeoxygenation (HDO). A supported Co-based catalyst will be subjected to reduction in H2 atmosphere, loaded with crude tall oil and model molecule (oleic acid) to evaluate the reaction mechanisms in the TOSCA instrument by Inelastic Neutron Scattering. We expect the results to provide key molecular insight into catalytic activity towards renewable fuels production through HDO of crude tall oil.

title: Investigation of possible quantum spin liquid ground state in 6H-hexagonal perovskite d5 iridates Ba3M4+Ir24+O9 (M=Ti, Zr) using Muon spin r

description: The 6H-hexagonal perovskite iridates Ba3M4+Ir2O9 with Ir4+ ions located on the vertices of a triangular lattice have been serving as the potential paradigm in search for the novel quantum spin liquids and other exotic quantum magnetic ground states. The M= Ti and Zr demonstrate absence of magnetic ordering via featureless paramagnetic-like dc susceptibility curves as well as missing anomaly in the specific heat data, despite having considerable antiferromagnetic Ir-Ir exchange interaction, thus marking both these d5 iridates as candidate materials for exhibiting strongly spin-orbit entangled dynamic quantum spin liquid ground states, which therefore warrants in-depth local probe muon-spin-relaxation/rotation (�SR) investigations to ascertain the true quantum magnetic ground states and consequently, to authenticate(refute) the dynamic(static) nature of the Ir-magnetic moments.

title: Structure of Aluminoborosilicate Glasses: Role of Alkali Modifier

description: Oxide glasses are one of the most important material families, but their applications are severely restricted by the main drawback of glass, namely high brittleness. The relationship between glass structure and mechanical properties thus needs to be established. Aluminoborosilicate (AlBSi) glasses form the basis for a wide range of commercial glass products, but the role of alkali modifiers on their structure and mechanical properties is not well understood. Our aim with the current proposal is to collect neutron scattering data at the SANDALS diffractometer from AlBSi glass compositions with different alkali oxides (Li, Na, K). By doing so, we will obtain the neutron structure factor S(Q) to Q values &gt;40 Å-1, enabling high-resolution computation of the pair distribution function and thereby allowing precise quantification of bond lengths and coordination numbers. In total, we will study 14 different glass samples with varying B/Al ratios and isotopic substitutions, requiring 4 days of beamtime. The neutron data will be combined with other structural characterization (solid state NMR and X-ray scattering) and modelling (molecular dynamics and EPSR) techniques to obtain a detailed understanding of the effect of the alkali modifier on the glass structure across different length scales. We will correlate the obtained structural models of AlBSi glasses with the glasses’ mechanical behaviour, which will ultimately aid the design of oxide glasses with improved damage resistance.

title: Diffusion Mechanism in Choline Chloride Based Deep Eutectic Solvents: The Role of Hydrogen Bonding Network

description: Choline chloride (ChCl) based DESs are among the most prominent variety owing to their large availability and ease of preparation. But the microscopic diffusion mechanisms which are crucial for their applicability are not yet comprehensively understood. Our previous investigations on acetamide based DESs have revealed that molecular diffusion processes are correlated with the nature of hydrogen bond (H-bond) network and relaxation. In the proposed experiment, we aim to explore these correlations pertaining to the dynamics of cholinium ions in reline, glyceline and ethaline DESs, which are mixtures of ChCl with urea, glycerol and ethylene glycol, respectively. The results of the study will establish a link between the microscopic dynamical landscape and H-bond network enabling a deeper understanding about the origin of the bulk transport properties in these industrially relevant DESs.

title: The Effect of Electrolyte on Interfacial Structures of Oleo-Furan Sulfonate Surfactants in Mixtures at the Air-Water Interface

description: Anionic surfactants such as linear alkylbenzene sulfonate (LAS) are the most used and best characterised commercial surfactants used in detergent products but can involve the use of petrochemicals, toxic catalysts or expensive feedstocks, making them an unsustainable option for the future. This has led industries to try to move towards more biobased and renewable surfactants, however none of these are yet scalable to the extent of current commercial surfactants due to high production costs and/or reduced performance. This research is focused on a bio-sourced ring-based anionic surfactant that has been shown to have high performance and high tolerance for hard water ions when alone in solution. We will investigate how the composition at the air-water interface, in mixed solutions of the anionic surfactant with a standard non-ionic surfactant, are affected upon the addition of mono- and di-valent electrolyte ions.

title: Spin dynamics in pyrochlore Nd2Mo2O7 in high longitudinal-fields

description: Most of Nd-pyrochlores show all-in-all-out long-ranged order ground state at low temperatures. However, Nd2Mo2O7 reveals two-in-two-out spin ice like state at low temperature, and possesses delocalized electrons which may host novel phenomena associated with the interaction between the localized moments Nd3+ and the itinerant moment Mo4+. In particular, Nd2Mo2O7 exhibits unusual spin chirality. In our previous ?SR experiments on Argus, the LF relaxation spectra does not reveal the decoupling behaviors even in the fields of 4 K Gauss. This result is very unusual while comparing to other pyrochlore compounds which typically exhibit spectra decoupling in lower fields of several hundreds Gauss. We thus propose to continuously study the spin dynamics in Nd2Mo2O7 in higher applied fields on Hifi.

title: Linking pore-size, local atomic structure and electrochemical properties in hard carbon anodes for sodium-ion batteries

description: Hard carbons are promising anode materials for sodium-ion batteries. However, explicitly linking electrochemical properties to the underlying structural mechanisms, and ultimately the synthetic route, is challenging due to the disordered, multi-length scale features of both the carbons themselves, and the sodium-insertion products. Here we propose to collect small- and wide-angle (total scattering) data on a series of hard carbons with a range of average pore sizes as a function of Na-insertion to determine which areas of the carbon are suitable for the formation of quasimetallic sodium nanoclusters, giving clues as to whether pore size or local structural/electronic environment limits the cluster size and hence low-voltage capacity.
