title: Inelastic Neutron Scattering Study of Crystal Field Excitations in Kondo lattice system CeRh2Ga2

description: CeRh2Ga2, which crystallizes in a CaBe2Ge2-type primitive tetragonal (space group P4/nmm) structure, is found to exhibit Kondo lattice heavy fermion state without any magnetic ordering down to 2 K. Both electrical resistivity and heat capacity show an anomaly near 255 K. The origin of this transition is not clear, however, a structural transition seems to provide the key. Further, the electrical resistivity of annealed sample show an upturn at low temperature which has been proposed to have its origin in Weyl-Kondo semimetal behaviour. In order to understand the origin of this resistivity anomaly the information about the magnetic excitations is highly desired. We propose to carry out inelastic neutron scattering measurement on CeRh2Ga2 using MERLIN/MARI.

title: Searching for Exotic Quantum Phenomena in the Magnetic Structure of CeAl2 around a Quantum Critical Point

description: Temperature and pressure combined allow the study of a wide range of phase space and can lead to the formation of new quantum phases including unconventional superconducting states, with fascinating scientific and, based on enhanced understanding, technological potential. Our recent low temperature resistivity measurements on high purity samples of the antiferromagnet CeAl2 show evidence for a new, as yet unidentified, phase emerging in the vicinity of a quantum critical point when the antiferromagnetic order is suppressed with pressure. The aim of this proposal is to determine the low temperature, high pressure magnetic structure of CeAl2, in particular focussing on the applied pressure region around the quantum critical point. Unusually in this region we see the transformation from a metallic state to an insulating state in our recent resistivity measurements, and a linear temperature exponent of the resistivity. These results are highly surprising. To date, there is no low temperature, hydrostatic high pressure neutron magnetic structure data on CeAl2. To understand the unusual behaviour as the quantum critical point is approached, we need to determine how the magnetic structure evolves with pressure.

title: Developing a machine-learning-assisted inherent strain method for fast and reliable residual stress and distortion prediction in LPBF components

description: This project aims to develop a machine-learning-assisted (MLA) inherent strain (IS) method for fast and accurate residual stress and
distortion prediction for real-size Hastelloy X components manufactured through laser powder bed fusion (LPBF). Currently employed
IS methods for LPBF deviate from the original IS framework and come with limitations as they assume a constant thermomechanical
history all over the part. Instead, we propose to employ artificial neural networks (ANNs) to learn the relationship between site-specific
IS values and geometrical features of the part first based on simulations. The ANN aims to approximate the non-uniform IS field of the
entire component as unique source of residual stresses. This proposed method is in line with the original framework behind the IS theory.
Once established, the proposed framework brings a drastic reduction in computational cost. The approval of this beam time request
allows to additionally train the ANN based on experimental data, and thus, it is expected to improve the reliability and accuracy of
the proposed method.

title: Structural Evolution of NaNiO2 Via Operando Neutron Diffraction

description: We propose to measure operando NPD of NaNiO2 vs. Na metal using POLARIS, to study the dynamic crystallographic structure of NaNiO2 as it charges from OCV to 4.5 V, and discharges to 1.25 V. Operando experiments will capture evolution of the superstructure lattice in Na1-xNiO2 through tracking of emergence, shifting, and disappearance of peaks in the low Q-range (~1.4 – 2.2 Å-1). Bragg diffraction will be analysed via Rietveld co-refinement with SRXD data from I11, using TOPAS 7. Data will be used along with complementary ex-situ NPD, ssNMR, XPDF, SQUID, and DFT to elucidate the novel phases bulk and local structures, and their formation mechanisms. Following discussions with instrument scientists, the POLARIS instrument is believed to ideally suit the requirements of operando experiments due to its high neutron flux, minimising collection time, maximising measurements taken per cycle, and improving signal-to-noise (aiding in capturing low-intensity superstructure peaks). NPD provides excellent contrast between the three elements present (bNa= 3.63 fm, bNi = 10.3 fm, bO = 5.80 fm), with enhanced sensitivity towards lighter elements Na and O), providing high confidence in fitting the O atomic positions via Rietveld refinement. Additionally, POLARIS’ wide Q-range may facilitate collection of total scattering data for NPDF analysis, offering insight into the dynamic evolution of the JT-distortion in NaNiO2, through operando tracking of Ni-O bond lengths for the first time.

description: In this proposed experiment, we will study two bioformulation/surfactant systems using an
automated sample preparation platform and artificial intelligence agent to guide the
experiment. We will quantify each prepared composition with three measurement modes
(SANS, light-scattering, viscosity) and the agent will use this information to optimally guide
phase-mapping and property optimization campaigns. Beyond this, the created multi-modal
datasets will be pubically released so that other researchers can develop new structureproperty
relationships and theories on these systems.

title: Characterization of a set of specimens of wootz steel. Wootz type identification and texture distribution analysis in cementite

description: A long term collaboration between CNR (Florence), the ISIS neutron and muon source, and the Wallace Collection (London) was established several year ago to determine the compositional and microstructural characteristics of the so called wootz steel. Wootz steel is a crucible steel that originated in the mid-1st millennium BC in South India, and sword blades made from Indian steel were highly prized and gained a legendary reputation for their quality. Wootz steel exhibits a peculiar pattern at the surface often defined as “watered silk” that originates from the manufacturing method, not fully known nowadays. It is believed to be a crucible steels which have been very slowly cooled to give dendrites of cementite and then carefully forged so that the dendrites are broken up and enabled to form a pattern. A set of 12 cut blade fragments from different swords were cut by conservators of the Nizam Armoury and shipped to the Wallace Collection conservation department for analysis purpose. We intend to perform diffraction measurements on the whole volume of the specimens. Once identified genuine wootz blades, based on the microstructure and the crystalline phases present, we intend to mount them on the goniometer and measure the cementite profile for several sample orientation in order to cover a wide solid angle range and check the relative intensity variation of the sensitive cementite peaks to gain insight about cementite anisotropy and texture.

title: Magnetic ground state determination of the chalcomenite compound CuSeO3.2H2O

description: In the past two decades, the renaissance of multiferroics and the experimental discovery of skyrmions in MnSi has generated an explosion of interest in complex magnetic structures, especially for non-centrosymmetric cases. The chalcomenite mineral of formula CuSeO3.2H2O crystallizes in the non-centrosymmetric space group P212121. Susceptibility measurements reveal two anomalies: a broad peak at ~45 K, extending over a temperature range of 20K and likely due to the presence of short range interactions and a sharp peak at TN~26K (also seen in specific heat) signalling the onset of long range magnetic order. The crystal structure is built up from Cu(II) atom connected through the SeO3 bonds to other three copper atoms, giving rise a compact three dimensional network. From the presence of three exchange coupling paths, a complex magnetic ground state can be anticipated and is indeed seen in preliminary neutron data. The Cu...Cu connections through the SeO3 groups along the b-axis likely contribute to the short range order whilst. Due to the intrinsically low magnetic signal of the Cu(II) ions (S=1/2), we apply for 3 days on WISH with the goniometer to collect data at 1.5K and 50K to determine the ground state magnetic structure as well as looking for diffuse scattering just above TN.

title: PfEMP1-membrane interactions in the presence of the mammalian receptors EPCR and ICAM1

description: Cerebral malaria is the most severe complication of infection by Plasmodium falciparum malaria parasites. The parasites express members of the variable adhesion protein family, known as PfEMP1, onto the surface of Infected erythrocytes (IEs). We have previously established that severe outcomes of P. falciparum infection is associated with PfEMP1 binding to the human endothelial protein C receptor (EPCR) and ICAM1. More recently, we have collected the Cryo-TEM the structure of the ectodomain of the HB3-var3 PfEMP1 variant (here named sHB3-var3) alone and in complex with EPCR and ICAM1. We have also collected QCM-D and NR data that showed sHB3-var3 selective affinity for lipid membranes containing anionic phospholipids. We are now interested in investigating how the binding of sHB3-var3 to EPCR and ICAM1 affect the sHB3-var3 location on the bilayer surface.
