title: Applications of muon in cancer research

description: Even though there are several existing methods for detection of molecular oxygen in tissues, new noninvasive methods are needed to measure the presence of hypoxia, its extent and spatial distribution within tumor. Using quantum beam of muon, a new noninvasive method to observe the three-dimensional images of concentration of oxygen in tissues is proposed here. We have already confirmed the reliability and sensitivity of the proposed method to low oxygen concentration in water and dilute aqueous biological solutions. Before applying to real biosamples and applications towards clinical/medical purposes for tumor/cancer diagnosis/treatment, we would like to perform systematic study in different hemoglobin (Hb) concentrations (up to physiological concentration) in water, blood plasma, high Hb in blood plasma and inhomogeneous system of oxygen and Hb in in-vivo type experimental set-up.

title: Total cross section measurements of nuclear graphite and high density polyethylene

description: The experimental thermal neutron cross sections are important in nuclear data validation. The Evaluated Nuclear Data File (ENDF) library is a comprehensive repository of evaluated nuclear reaction data, including thermal neutron cross sections (thermal scattering laws, TSLs), for a wide range of materials. ENDF libraries importance lies in providing critical data for nuclear science and engineering applications, such as reactor design, nuclear medicine, and safety analysis, where accurate thermal neutron cross sections are essential for modeling neutron interactions and behaviors in various materials and environments. There are some known issues with graphite and polytethylene TSLs in the ENDF/B-VIII.0 and ENDF/B-VIII.1 releases, hence we would like to perform some transmission (total cross section) measurements to rectify these issues. We would also like to use these measurements on graphite to characterize the impact of small angle neutron scattering on the total cross section, as well as to validate the models used to calculate this contribution.

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: Investigating the Interplay Between Carbonation Kinetics and Water Dynamics in Cementitious Materials Using Inelastic Neutron Scattering

description: The use of concrete has been growing continuously in the 20th and 21st centuries. The manufacture of cement, the ‘glue’ in concrete, is associated with significant CO2 emissions accounting for approx. 7% of the anthropogenic CO2 emissions in the world. The current global warming crisis and the significant consumption of natural reserves have pushed the building industry to search for new and sustainable solutions. New breakthrough technologies for lowering the CO2 footprint include a circular utilization of demolished concrete. This technology, currently under development by the cement industry, consists in the reactions between the hydraulic cement components and their hydration products with carbonate ions (from the injected CO2) in a humid environment, which lead to the formation of carbonate minerals and therefore to the permanent storage of the CO2 in solid form. Here, we aim to understand the role of the water dynamics on carbonate mineral formation pathways in the complex environment of a recycled cement paste using Inelastic Neutron Scattering. This project is part of a collaborative research PhD project led by ISTerre (CNRS & Univ. Grenoble Alpes) in collaboration with Heidelberg Materials.

title: Tuning Orbital Order in Fluoride Perovskite KFeF3 via high pressure

description: Oxide-based perovskites have received significant interest through extensive structural and theoretical studies, however the adjacent playground of the fluoride analogues, ABF3 have comparatively attracted far less attention. While previous high resolution PXRD analysis has elucidated orbital order in some of the fluoride perovskites such as NaCrF3, KCrF3, NaCuF3 and KCuF3 exhibiting eg active JT distortions at room temperature, there has been little work exploring cooperative JT distortions associated t2g degeneracies in these systems. Here we propose a high-pressure neutron diffraction experiment on PEARL to probe the interplay between octahedral tilting and orbital ordering in KFeF3, and overlooked member of the ABF3 family that has such a t2g degeneracy. These experiments will shed fundamental insight on the interplay between orbital and tilt degrees of freedom in the fluoride perovskites, helping unlock their potential for use in functional materials in emerging technologies such as battery cathodes and memristive devices.

title: Multi-Session Visual SLAM for Illumination-Invariant Re-Localization in Indoor Environments

description: For robots navigating using only a camera, illumination changes in indoor environments can cause re-localization failures during autonomous navigation. In this paper, a multi-session visual SLAM approach is presented to create a map made of multiple variations of the same locations in different illumination conditions. The multi-session map can then be used at any hour of the day for improved re-localization capability. The approach presented is independent of the visual features used, and this is demonstrated by comparing re-localization performance between multi-session maps created using the RTAB-Map library with SURF, SIFT, BRIEF, BRISK, KAZE, DAISY and SuperPoint visual features. The approach is tested on six mapping and six localization sessions recorded at 30 minute intervals during sunset using a Google Tango phone in a real apartment, which is the dataset provided here. This dataset has been used to evaluate the approach used in this paper: M. Labbé and F. Michaud, “Multi-Session Visual SLAM for Illumination-Invariant Re-Localization in Indoor Environments,” in Frontiers in Robotics and AI, vol. 9, 2022.

title: Investigation of crystal field excitations in Ba3RRu2O9 (R= Tb, Nd)

description: The 4d-4f based magnetic materials have garnered a lot of interest due to competing magnetic exchange interactions. In the present proposal, we focus on Ba3TbRu2O9 and Ba3NdRu2O9 compounds of Ba3RRu2O9 (R is rare-earth) series. The hexagonal crystal structure of these compounds is quite interesting where Tb/Nd octahedra (Tb/NdO6) and Ru dimer (Ru2O9) form a triangular lattice in the ab plane. The dc magnetization study infers antiferromagnetic and ferromagnetic transitions in Ba3TbRu2O9 and Ba3NdRu2O9 compounds, respectively. The analysis of inverse susceptibility data of Ba3TbRu2O9 compound reveals the effective magnetic moment ~7.64 muB which is close to ~7.94 muB expected for Tb4+ (4f7) ions rather than that ~ 9.72 muB for Tb3+ (4f8) ions, indicating the Kramer’ ion character of Tb ions. The inverse susceptibility data of Ba3NdRu2O9 compound is better analyzed using a two-level model. The analysis reveals the splitting of energy levels under the crystal field and the calculated energy gap of ~16.5 meV is found close to the literature reported value of ~12.5 meV for isostructural Ba3YRu2O9 compound. However, a microscopic INS (inelastic neutron scattering) study is required to understand crystal field effect excitations in Ba3RRu2O9 (R= Tb, Nd) compounds, which has not been explored so far in these compounds. We propose a first comprehensive crystal-field-excitation study on Ba3TbRu2O9 and Ba3NdRu2O9 polycrystalline compounds.

title: Investigating Se atom position and dimerization in new visible band gap semiconductor material YBi2O4Se

description: We have recently synthesized the new semiconductor (band gap = 1.2 eV) YBi2O4Se, which has Se in a formal oxidation state of -1 on a 2D square net. Density functional theory calculations demonstrate that Se(-1) dimerisation is required to open a band gap in the compound. Neither ordered or disordered dimerisation is observed using X-Ray diffraction, likely due to Se having 8 Bi nearest neighbours. Here we propose measuring the diffraction pattern as a function of temperature from base to room temperature to elucidate the Se(-1) position and dynamics in this new family of visible gap semiconductors.

title: Unravelling spin dynamics in a new triangular lattice antiferromagnet

description: Geometric frustration has been a hot topic in both experimental and theoretical condensed matter physic because of the possibility to realise novel magnetic ground states and exotic quantum excitations. It is well known that a triangular arrangement of magnetic moments with antiferromagnetic coupling is among the most representative models in frustrated magnetism. We have recently synthesised a new layered triangular lattice compound NdMgAl11O19 in which Nd3+ ions are arranged into a perfect triangular lattice in the ab plane. In order to unravel the unusual spin dynamics in NdMgAl11O19, we would like to propose a comprehensive muSR study of a large quantity powder sample (~5 g) in the temperature range of 0.05-20 K at the RIKEN-RAL muon instrument ARGUS or CHRONUS. We request 3 days of beamtime.

title: Investigate phonon excitations in the strong magnetoelastic and magnetoelectric TbPO4

description: TbPO4 exhibits one of the strongest magnetoelectric (ME) coupling among bulk materials. This effect is intimately related to a substantial magnetoelastic coupling, revealed by our preliminary work. The large magnetoelastic effect and structural deformations characterizing the compound play a key role in developing such a strong ME effect. Previous studies suggest that TbPO4 crystal structure can easily distort, giving rise to soft phonon modes behavior. Yet the phonon spectra of TbPO4 remain uninvestigated with neutron spectroscopy and modern DFT methods. Here, we propose to study the phonon spectra on MERLIN, with a special focus on the crossing point of phonon modes with crystal electric field levels. At these points, we expect to see the footprint of the very large magnetoelastic coupling. The result will contribute to understanding the mechanism behind both the magnetoelastic and magnetoelectric effects. We started a DFT calculation and the neutron data are essential to elucidate the phonons dispersion spectrum and deepen the DFT calculations.
