title: Proximity-Induced Magnetism in CrTe2/Bi2Te3 Ferromagnet-Topological Insulator Heterostructures

description: Topological electronics explores novel quantum properties encountered in topological insulators (TIs). TIs exhibit remarkable features, including dissipationless carrier transport through their surface states. When TIs are magnetically doped, they can display the quantum anomalous Hall effect (QAHE)—a zero-field version of the ordinary quantum Hall effect. However, due to defects associated with doping, the useful temperature range for QAHE is limited. By bringing a magnetic material close to a TI, the TI’s surface states can acquire magnetic properties via proximity-induced magnetism (PIM). We recently discovered that Mn diffusion in the leading Mn-based heterostructures can mimic the elusive PIM effect at the interface.

To address this problem, have recently studied the NiO/Bi2Te3 system with PNR, and found that despite its superb structural quality, the magnetic complexity of the NiO layer makes drawing unambiguous conclusions about PIM difficult. Here, we propose to study CrTe2/Bi2Te3 heterostructures by PNR, which have two outstanding properties. First, the 1T- CrTe2 layer has a well-defined (out-of-plane) magnetic anisotropy. Second, since the nuclear SLD of the two layers is very similar, small changes in the magnetic SLD at the interface will have a huge effect on the spin asymmetry, hopefully allowing, for the first time, to get unambiguous proof of the existence of the elusive PIM effect.

title: Non invasive illicit substances detection with slow neutrons: a feasibility study towards practical application

description: The growing scale of the devastation which can be caused by even a single terrorist attack requires more effective methods for the detection of hazardous materials. In particular, there are no solutions for effective monitoring of threats at sea, both for the off-shore infrastructure and ports. Currently, the state-of-the-art methods of detection provide the determination of the density distribution and the shapes of tested subjects but do not allow for exact identification. The aim of this proposal is to conduct a feasibility study of the possible subsequent usage of several methods available on VESUVIO to detect illicit substances. We plan to perform a series of measurements using the VESUVIO spectrometer using surrogates of the explosives and drugs to determine their signal characteristics and limits of detection and quantitation.

title: The inelastic neutron scattering spectra of diphosgene and triphosgene

description: Phosgene is one of the most important C1 synthons in chemical industry. In a research laboratory, phosgene is often substituted by trichloromethyl chloroformate (diphosgene) or bis(trichloromethyl) carbonate (triphosgene), which react similarly to phosgene and are much easier to handle. Crystal structures of both compounds have been reported, however, as far as we are aware, no solid-state vibrational spectroscopy studies are documented. In view of their synthetic importance and as possible contaminants in the industrially important phosgene, we propose to carry out a comprehensive study of the vibrational spectra. The INS spectrum is essential in this regard, as it provides access to all the modes, in particular the low energy modes below 400 cm-1 that are difficult to access with conventional vibrational spectroscopy.

title: Does oxidative damage to mammalian membranes make them susceptible to antimicrobial peptides?

description: The antibacterial peptide protegrin inserts preferentially into bacterial model membranes, which are negatively charged, compared to mammalian model membranes which carry no net charge. Oxidation of lipid membranes is now known to change their interaction with peptides, often considerably. In this proposal we wish to determine if oxidation of model mammalian membranes, leading to carboxylic acid groups in the lipid tail which will i) be predominantly deprotonated at pH 7.4, and ii) subsequently reorientate so that the carboxylate group can interact with the lipid head region, leads to increased interaction with the antibacterial peptide protegrin.

title: Phonon dispersion of the battery electrolyte parent material Li7La3Zr2O7

description: Ionic conductivity is central to many green technologies, including the Li-batteries that are now ubiquitous in our daily lives. In this context, there has been a recent drive to discover solid electrolyte materials that have conductivities approaching those of current state-of-the art liquid electrolytes. This is because solid electrolytes promise safer, more reliable, and longer-lived batteries. One particularly promising family of solid electrolyte materials is Li7-xLa3M2-xZrxO12 (M=Ta,Nb) (LLZO). We have recently carried out quasi-elastic neutron scattering experiments with polarization analysis to investigate the diffusion mechanism in one member of this family. We observed two dynamic processes, likely corresponding to local hops and long-range diffusion of lithium. Modelling of this spectrum is currently ongoing using state-of-the-art machine-learning-based molecular dynamics simulations. To complete our understanding of the diffusion mechanism in LLZO, we now wish to turn to the role of lattice vibrations – phonons – in promoting diffusion. As a first step to achieving this, we wish to carry out the first inelastic neutron scattering study on the non-conductive end member compound Li7La3Zr2O12.

title: Magnetic structure of S = 1 dimer compound K2Ni2(SeO3)3

description: Topological structure plays a crucial role in the magnetism of quantum magnets. The S = 1 antiferromagnet K2Ni2(SeO3)3 has a triangular-lattice structure composed of perpendicular-to-plane Ni2 dimers. Surprisingly, K2Ni2(SeO3)3 exhibits two-step antiferromagnetic transitions at TN1 and TN2, whose values are magnetic-field dependent, and a 1/3 magnetization plateau at 2 K, which is typical for triangular-lattice antiferromagnet rather than the S =1 dimer compound. We propose to collect NPD data to determine the nature of the observed magnetic transitions and to shed more light on why the compound behaves like a TLAF rather than a spin-dimer antiferromagnet.

title: RADNEXT: TA09-289: Muon-Induced Events in Dynamic Operation

description: Muons are expected to be a serious concern in advanced technologies. In the literature, there are several reports of muon-induced single events in SRAMs, mainly focusing on the technology node, dependence on the bias voltage, difference between muons and antimuons (hereafter, negative and positive muons), etc. However, radiation tests are usually performed in static mode, just writing a pattern, irradiating, and reading back. This procedure is quite simple but it is not representative of actual operation of the SRAMs. Indeed, no report has been found in the literature relating muons and dynamic tests on these memories.

In this proposal we would like to characterize commercial CMOS 40-nm SRAMs under muons while typical dynamic tests, such as March-C or March-D, are run. For other kinds of radiation, the sensitivity increases and other less common phenomena can occur. It is possible that similar results appear with muons, but they should be investigated.

title: Nano-Sized Effects on Spin Dynamics of La2-xSrxCuO4 Nanoparticles

description: Magnetic nanoparticles raised great attention in both fundamental and application aspects. The magnetic properties possess significant differences from that observed in the bulk case. In the case of high-Tc superconductor cuprates, La2-xSrxCuO4, a hysteresis loop at 300 K was observed when the particle size was reduced to 64 nm. Other non-magnetic nanoparticles reported similar behaviour but the reason for the appearance of magnetism is not well explained yet. In addition, in a high-Tc superconductor, it is believed that superconducting and magnetism are intertwined with each other which is proposed to explain the origin of the superconductivity. Here, we propose to study nano-size effects on the magnetic state and spin dynamics of La2-xSrxCuO4 nanoparticles.

title: Residual stress profiles in coated riveted joints of dissimilar materials using SPR joining technique

description: The United Kingdom has set a formidable net-zero target of 100% emission reduction by 2050, emphasising the urgent need for progress in sustainability efforts. Given the significant role of the automotive industry in CO2 emissions, there is a growing demand for lightweight multi-material structures to mitigate environmental impact. Carbon fibre reinforced polymer (CFRP) and Aluminium (Al) have emerged as pivotal materials due to their superior strength-to-weight ratio, particularly in the context of vehicle electrification. However, understanding and mitigating joint failure resulting from residual stresses in the Self-piercing riveting (SPR) process remains a critical area of investigation. Prior studies have successfully quantified residual stresses in SPR joints, primarily focusing on similar metallic materials. This current research extends the inquiry to encompass both dissimilar materials i.e. CFRP-Al with carbon steel rivet joint, with a particular emphasis on the resistance encountered during rivet insertion, potentially leading to stress-induced failures. Employing various coated rivets (carbon and Aluminium-based) with distinctive characteristics, this study aims to unravel the intricate interplay between surface properties, coating hardness, and residual stress formation during SPR joining, ultimately enhancing our comprehension of these critical structural elements.

title: α-Synuclein Membrane Aggregation

description: Parkinson’s disease is a neurodegenerative disorder marked by the loss of dopaminergic neurons in the brain, resulting in motor deficits. Key to its pathology are Lewy bodies, aggregates of α-Synuclein, pivotal for normal neuronal function but prone to forming pathogenic structures. Notably, α-Synuclein undergoes conformational changes on cell membranes, contributing to its aggregation into toxic forms, a crucial event in disease progression. Understanding these interactions is vital for deciphering Parkinson's disease and developing therapies. Our proposal plans to use SANS to study the aggregation of a model lipid-α-Synuclein system, aiming to elucidate the nanostructures and understand the mechanisms and ways to inhibit this process. Additionally, our collaborator UCB is advancing Minzasolmin in phase 3 trials, targeting α-Synuclein aggregation as a potential therapeutic avenue.

description: YbZn2GaO5 has been identified as a candidate U(1) Dirac QSL without structural disorder on the basis of x-ray diffraction studies. However, for x-rays, there is limited sensitivity to the O sublattice and little scattering contrast between Zn and Ga. We have already identified the presence of structural disorder for YbZn2GaO5 using single-crystal diffuse neutron scattering on SXD. We now propose to study the intrinsic structural disorder quantitatively using total powder neutron scattering on Polaris for YbZn2GaO5 and the new related material TmZn2GaO5.
