title: Effect of microstructure and punching method on residual stress formation of punched thick-plate advanced high-strength steels

description: Advanced high-strength steels (AHSSs) represent a promising advancement in materials for the automotive industry due to their exceptional combination of strength, ductility, and formability, offering a compelling alternative to conventional high-strength low-alloy (HSLA) steels. AHSSs, with a higher strength-to-weight ratio than that of HSLA, allow for the design of thinner gauges, resulting in substantial weight reduction and consequent fuel savings. However, applying AHSSs in the thick-plate configuration for heavy-duty trucks remains a challenging endeavor. This challenge stems from the sheet shearing processes required to manufacture chassis components, such as hole punching and trimming. 
These processes more adversely affect the fatigue properties of AHSSs compared to conventional HSLA steels due to introducing a rougher surface inside the punch, as well as a more pronounced shear-affected zone, and particularly higher residual stress accumulation around the punched area. Consequently, heavy-duty trucks still predominantly rely on conventional HSLA steels, and the full potential of AHSSs remains unrealized in these applications. To address this limitation and optimize the integration of AHSS steels in heavy-duty trucks, a comprehensive understanding of punching effect on fatigue behavior is essential. This study aims to particularly focus on quantifying the residual stress resulting from punching in AHSSs with different microstructures and hole geometries.

title: Understanding the organization of phenylalanine in and around a model cellular membrane

description: Phenylalanine (Phe) is one of the essential amino acids that act as a precursor for the synthesis of various neurotransmitters. Imbalance of these molecules causes many diseases (e.g. Phenylketonuria, Alzheimer’, etc) which are mainly associated with the self-assembly of toxic fibrillar aggregates of Phe around the brain membrane. It is important to investigate effects of such Phe fibrillar aggregates on the cell membrane to understand the mechanism of their adverse actions. Present study will provide a molecular level description of this assembly in the model brain membrane which will be quantified by the neutron reflectivity.

title: Investigation of elemental composition of dynastic Mughal Blade from The Royal Collection through non-invasive methods

description: The sword under investigation is of extraordinary importance to the history of Moghul arms and armour. It is inscribed on both sides of the blade with Persian verses and the title of the emperor for whom it was made, Jahangir (r. 1605-1627). Further inscriptions demonstrate that the sword was inherited by his son and successor Shah Jahan (r. 1628-1658) and by his successor ‘Alamgir (r. 1658-1707). Mughal swords with known provenance are extremely rare and this would be one of the earliest royal Mughal blades to be analysed. It has also been suggested this blade may be one documented in contemporary accounts as being made for the emperor from meteoric iron. A number of Mughal blades, including another owned by Shah Jahan himself were analysed with neutron methods. In addition, about 72 Indian blades from the Wallace Collection have been analysed at ISIS using the INES instrument since 2015, as well as a number from the princely Arsenal of Hyderabad.
The analysis aims to identify the composition of the blade, particularly in terms of the carbon content and its distribution along the blade, and nickel content, if present, to determine whether meteoric iron was used in the manufacturing. Testing will also ascertain what metalworking processes the blade has been through (forging and heat treatments). This would be the earliest Mughal sword to be investigated, and would provide an invaluable benchmark for the field.

title: Neutron Reflection Studies for the Strong Insertion of Sphingosine in Lipid Membrane at the Solid/Liquid Interface

description: Sphingosine, an important component of the sphingolipids, serves as the backbone of the sphingolipids, and works as the signal molecule to regulate cell fate. The incursion of sphingosine into membranes is always accompanied by an increase of membrane permeability, which results in the leakage from the cytosol, and eventually the cell death. The reason why the sphingosine increases the membrane permeability is currently unclear, but structural changes in the membrane after incorporating sphingosine must play an important role. We propose to use neutron reflectivity (NR) combining with deuterium labelling technique to investigate the planar lipid membrane structure at the solid/water interface in the presence of sphingosine with two various hydrophobic chains. This study will provide the basic understanding of the interfacial behaviour of sphingosine and will give constructive support to elucidate how the unique structure of sphingosine affect the membrane.

title: Determination of the solubility parameters and agglomeration behaviour of conjugated polymers and fullerenes via a binary solvent gradient method

description: Organic solar cells based on polymer and fullerenes depend upon solution processing such as spin coating, spray coating and inkjet printing. In order to be processed a high degree of polymer and fullerene in a given solvent. Determination of the solubility is often done using optical methods. However in opaque systems this is not possible. 

By using spin-echo SANS we will be able to detect the onset of the formation of structures, this is the solubility limit. Hence this very elegant method will allow us to achieve a more accurate determination of the solubility parameters of different polymers and fullerenes. This in turn will allow us to refine solar cell fabrication.

title: (H, Li)6Ru2O6 (Ru3+, Jeff =1/2): a novel Kitaev Quantum Spin Liquid alternative to 𝛼-RuCl3

description: Kitaev Quantum Spin Liquids (KQSL) host novel ground state and excited state properties. A prominent example is α-RuCl3 having Ru3+ (Jeff = 1/2) on a honeycomb lattice. In zero applied field this compound is magnetically ordered and a field of 80 kOe is required to suppress the order and reveal the KQSL state. Herein we report the synthesis of (H, Li)6Ru2O6, with Ru3+ (Jeff = ½) on a honeycomb lattice. Our heat capacity measurements suggest no ordering down to 400 mK in spite of a large Curie-Weiss temperature of - 44 K as extracted from our susceptibility data. Our 7Li NMR measurements find a power law variation of the 7Li spin-lattice relaxation rate below 40 K. From zero-field muon spin relaxation, we find neither oscillations in the muon asymmetry nor any 1/3 tail in the muon asymmetry suggestive of the absence of long-range order and of the presence of dynamic moments. These results are similar to those of H3LiIr2O6 (suggested to be a KQSL) except that the saturation of the muon depolarisation rate λ in (H, Li)6Ru2O6 sets in at 10 times the temperature in H3LiIr2O6. Based on our data, we propose that (H, Li)6Ru2O6 is a KQSL even in zero field.

title: Na Diffusion in Alkaline doped NASICON (Na3.1Zr1.95M0.05Si2PO12 (M = Mg, Ba))

description: NASICON, Na1+xZr2SixP3?xO12 (0 ? x ? 3), are known for good room-temperature Na-conductivities (~10?4 Scm?1), owing to the presence of a 3D cation transportation channel. Recently, alkaline doped NASICONs (Na3.1Zr1.95M0.05Si2PO12 (M = Mg, Ca, Sr, Ba)) were discovered and show promising Na- ionic conductivity at 300 K (~10?3 Scm?1). We propose to study the QENS and INS measurements of pure and alkaline doped NASICON to investigate the effect of doping on phonon spectrum and Na diffusion and their interplay. A larger alkaline element would be supposed to enhance the channel width for Na diffusion; however, it may also shift the phonon energies and locally distort the lattice, which could reduce the Na conductivity. The QENS and INS measurements will allow probing Na diffusion and the role of phonons in facilitating the Na hopping between available Na sites.

title: Single crystal study of the magnetic structure of a Pr-based antiferromagnet with competing interactions

description: Rare-earth based correlated materials often host competing interactions and electronic ground states associated with different degrees of freedom. We have examined a Pr-based antiferromagnet, which we find has an unusual magnetic phase diagram as a function of pressure and applied magnetic fields, exhibiting an intricate interplay of different magnetic and electronic states. We previously performed powder neutron diffraction measurements using the WISH diffractometer, which revealed antiferromagnetic Bragg peaks below the magnetic transition, as well as diffuse magnetic scattering. In order to unambiguously determine the complex magnetic structure, and to probe the nature of the diffuse scattering, here we propose a follow-up experiment to measure the low temperature single crystal neutron diffraction using WISH. Knowledge of the nature of both the long range and short range magnetic ordering will allow us to gain a microscopic understanding of the magnetism, and is important for modelling the magnetic phase diagram and revealing the mechanisms behind the unusual interplay of different phases.

title: CO2 fluidising Deep Eutectic Solvents

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 big drawback of DES is their high viscosities, which leads many researchers to add species such as water to fluidise them. However water is not compatible with all processes, so we have started a research program to explore fluidisation with CO2 instead. CO2 has no dipole moment so we expect quite different interactions with highly polar DES systems, to that of water. Here we propose to study the structure of a DES commonly used in biomass extractions choline chloride:oxalic acid: ethylene glycol, in the absence of CO2 and then at several different pressures of CO2 to determine how CO2 is incorporated into this liquid, and thus the mechanism for the observed viscosity reductions, and to link to biomass extraction efficiency in the fluidised DES.
