title: Investigation of Spin Correlations in the Frustrated Anisotropic Distorted Triangular Lattice Antiferromagnet Na2CoGeO4

description: Two-dimensional distorted triangular lattice antiferromagnetic (TL-AFM) spin systems show unique magnetic ground states as compared to their undistorted counterpart. However, the study of distorted triangular lattice is so far limited to J1-J2 models where J1 and J2 are the two non-equivalent nearest neighbour exchange interactions. Here, we propose a comprehensive neutron diffraction study on the distorted TL-AFM compound Na2CoGeO4, having three non-equivalent NN exchange interactions J1, J2, and J3, to determine the nature of magnetic ground state, as well as its temperature and field dependences by using the GEM diffractometer. The outcome of the present study will shed light on the magnetic correlations of a distorted triangular spin system beyond the J1-J2 model and is expected to open up a new direction in the frustrated spin-systems.

title: Search for the distorted counterpart of ice XV and hydrogen-ordered ice IV

description: Water ice displays a remarkably complex phase diagram. The last five years have seen rapid developments in this area of research with the discovery of three new phases of ice. Our team has been involved in the discovery of ice XIX and shown that ice XIX is a distorted version of the well-known ice VI. The type of distortion observed during the ice VI to ice XIX phase transition is similar to the ones observed for perovskites under pressure and we will now investigate if such distortions are also possible for ice XV, the hydrogen-ordered counter part of ice VI. Additionally, we will also search for the so far unidentified hydrogen-ordered counterpart of ice IV. In summary, these experiments may lead to the discovery of two new phases of ice. In any case, we will gain new and highly valuable insights into the low-temperature / high-pressure behaviour of ice.

title: Measuring magnetic anisotropy and magnetic excitations in staggered and chiral spin-1 chains

description: We plan to study two spin-1 antiferromagnets, where the Ni(II) ions are connected in (i) a staggered and (ii) chiral-chain structure. Previous studies of similar spin-1/2 Cu(II) systems revealed a host of exotic excitations that map on the soliton and breather modes of the sine-Gordon model of quantum-field-theory. Spin-1 chains, however, are known to differ fundamentally from their spin-1/2 counterparts, and the structure of these materials suggest the presence of an unusual, alternating single-ion anisotropy. We expect that the competition between the alternating anisotropy and antiferromagnetic could give rise to a unique excitation spectrum and promote spin canting, which is conventionally solely driven by the Dzyalonshinskii-Moriya. We propose to use zero-field inelastic neutron scattering, below magnetic ordering temperatures Tc = 2.3 K and Tc = 2.2 K, at LET to quantify the energy scales governing the magnetic properties and map the excitation spectra. The data collected at LET will supplement the magnetic neutron diffraction data collected at WISH and a suite of thermodynamic measurements.

title: Investigation of decane displacement mechanism during in situ supercritical CO2 injection in limestones and the study of additive performance

description: Carbon capture and storage (CCS) has been recognized key technology to reduce greenhouse gas emissions in an attempt to limit the effects of global climate change. Nowadays, carbon dioxide-enhanced oil recovery (CO2-EOR) has gained global attention in light of declining oil reserves. The potential of combining CO2-EOR technology with CCS has the benefits of enhanced oil recovery and permanent storage of an amount of injected CO2 in the depleted reservoir. In a previous NIMROD experiment we have examined the oil recovery at the nanoscale by injection of supercritical CO2 into a limestone sample loaded with decane. The neutron profiles showed the decane displacement as well as the structural properties of confined CO2 and the pore accessibility to CO2. It was also concluded that a large fraction of small mesopores were inaccessible, to CO2, suggesting that most of these pores are unavailable for storage for geologic CO2 sequestration. We have also observed that a total recovery was not achieved. We are now proposing to investigate if the remaining decane amount was entrapped over the limestone surfaces and through the pore throats or did not fully displaced due to the limited cell volume. Finally, the additive performance will be examined.

title: Comparing the Mode of Action of Two Membrane-Targeting Antiviral Peptides: A Neutron Reflectometry Study

description: There is significant interest in developing broad-spectrum antiviral peptides that inhibit membrane-enveloped viruses and to elucidate design principles that can aid antiviral peptide engineering to further improve potency and selectivity for eventual clinical translation. Within this scope, the AH and C5A peptides are two widely studied antiviral peptides, however, the atomistic details of how these two peptides distinctly interact with lipid membranes remains unknown. Addressing this gap is critical from a human health and safety perspective because the AH peptide selectively targets highly curved membranes such as those of virus particles and leaves human cell membranes unperturbed whereas the C5A peptide indiscriminately solubilizes high- and low-curvature membranes. In this project, we seek to employ neutron reflectometry to characterize how the AH and C5A peptides interact with supported lipid bilayer (SLB) platforms across several bulk peptide concentrations in order to determine the mode of action of each peptide. Our team is composed of expert researchers in the fields of antiviral peptides, model membranes, and neutron reflectometry, and we anticipate that the resulting insights from this project will provide unprecedented knowledge about the structure and function of membrane-targeting antiviral peptides, especially in combination with data from other ongoing experimental, modeling, and simulation efforts.

title: Magnetic ordering in layered cobalt oxide chalcogenides obtained by soft chemistry

description: This is a proposal to probe the crystal and magnetic structures of a series of layered oxychalcogenides containing infinite CoO2 layers in which the electron count and structural details are tuned using soft chemistry. Changes in magnetic ordering (structure and size of ordered moment) will be determined as a function of composition in members of the series AE2CoO2(Li1-x(Cu/Ag)x)2Ch2 (AE = Sr, Ba, Ch = S, Se) with formal Co oxidation states ranging from +2 to +3 for Co ions in unusual highly elongated octahedral environments.

title: Chasing a new paradigm in frustrated magnets : 1st experiment on rare earth antiperovskite (WISH)

description: Our recent theoretical work suggests that the antiperovskite lattice with Ising spins can host a variety of exotic phases and be a promising new playground for frustrated magnets with fragmented spin ice states and emergent monopoles. Experimental realizations of such an idealized system are needed but the required topology using large Ising spins is difficult to achieve due to chemical constraints. We have identified a suitable candidate in Ho3(PN4)O which has recently been synthesized via a high pressure-high temperature route. We propose neutron powder diffraction measurements at ultra-low temperatures on this new compound to determine the ground state of this exciting new rare-earth anti-perovskite within the context of our theoretical work. We have also applied for muon spin relaxation measurements on EMU in this current round.

title: Crystal field excitations in the lanthanide-based square lattice magnets LnKNaNbO5

description: We propose to study the crystal field levels in the lanthanide-based square lattice compounds LnKNaNbO5 (Ln=Pr, Nd) with a Ln=La compound used as phonon blank. The aim of the proposal is to contrast and clarify the crystal field level scheme in non-Kramers (Pr) and Kramers (Nd) members of the series. The results will facilitate modelling of our temperature and magnetic-field dependent magnetization data, and will allow us to evaluate the exchange and anisotropy energy scales characterizing these compounds.

title: Temperature dependence of overdamped 2D fluctuations in metal halide perovskites

description: All inorganic perovskites has been attracting great attentions because of their promising optoelectronic properties, ultralow thermal conductivity for both photovoltaic and thermalelectric applications. Zone-boundary soft modes that associated with the octahedral rotations has been found to be highly anharmonic and closely related to the phase transitions driven by structural distortion. It remains unclear whether these overdamped modes behave similarly with the soft modes found in oxide perovksites that will harden on warming above phase transition temperature, and how the competition between M and R distortions evolves away from the phase transitions. The different ground state structure of Sn-based and Pb-based halide perovskites may also result in different temperature dependence of the anharmonic phonon modes in cubic phase. We propose to measure CsPbBr3 and CsSnBr3 in high temperature range to reslove these questions regarding their unusual atomic dynamics, which is crucial for further optimization of their optical and thermal properties.
