title: Probing topologically enhanced interface magnetism

description: Topologically nontrivial materials are a material class which has emerged over the past decade+ as a critical area of research due to promise for ultra-low power computing or fault-tolerant quantum devices. As the classes of accessible topological materials have expanded, transitions between topological states may enable a wide range of new devices. In particular, the Dirac semimetal ZrTe5 is near a transition to both weak and strong topological insulating states, which may enable tuning in and out of macroscopic quantum transport conditions. Here, we propose to study the introduction of magnetic order in to ZrTe5 by the magnetic insulator EuS, as the time-reversal symmetry breaking induced by magnetic order at the surface is crucial to realizing the quantum anomalous Hall state in this material.

title: The coupling of charge density wave and host structure in La2-xSrxCuO4

description: Soon after the discovery of superconductivity in the cuprates it was proposed by Zaanen, Gunnarsson, and Machida that they should also show charge/stripe order for a dopings near p=1/8. Recent experiments have shown the uniaxial stress can indeed create a 1-D stripe structure in La2-xSrxCuO4. Here we propose to study the structure of La2-xSrxCuO4 under uniaxial stress to see how it is modified. This will allow us to determine whether 1-D stripe patterns are intrinsic to the CuO2 planes or due to a coupling to a low symmetry host structure.

title: Low energy magnetic spectrum of the octupolar-dipolar quantum spin liquid candidate Sm2Zr2O7

description: A relatively unexplored source of novel states in Rare Earth pyrochlore is predicted in the “Dipolar-octupolar” pyrochlores R2M2O7 (R=Ce, Sm, Nd; M=Zr, Hf, Ti, Sn, Pb). Of this family, Ce2Sn2O7 and Ce2Zr2O7 have been highlighted recently as showing evidence of quantum spin liquid physics with neutron scattering results for Ce2Zr2O7 bear ing encouraging similarity to predictions for a U(1) quantum spin liquid. Here we wish to perform the first exploration of the low energy magnetic excitations of another octupolar-dipolar quantum spin liquid candidate, namely Sm2Zr2O7.

title: In-situ simultaneous SANS and diffraction measurements to unravel controlling mechanisms of delayed phase separation in stainless steels

description: Duplex stainless steels, containing approximately equal amounts of two different phases (ferrite and austenite) are used in various demanding industries that require excellent corrosion and mechanical properties such as nuclear or gas industry. However, they are prone to embrittlement when exposed to elevated temperatures for a prolonged time, which limits the applications and the lifetime of components. This is linked with so-called phase separation that occurs in ferrite. It has been observed that this embrittlement can be delayed by different heat treatments, but the mechanisms that lie behind this delay are still unknown. By analysis of the phase separation in-situ (while performing the different heat treatments), we can separate different potential mechanisms for this delay and increase our understanding, which will help us to control phase separation in the future.

title: Affibody labelled lipid nanoparticles for cancer therapeutics

description: Heralded by their unprecedented success in the Covid-19 vaccines, lipid nanoparticles (LNPs) are revolutionizing RNA medicine. To apply LNP technology to other crucial healthcare questions, e.g. cancer immunotherapy, new LNP formulations are required which can selectively target certain cells in the body. We are addressing this by specifically labelling LNP surfaces with affibodies to target specific cell surface receptors. Affibodies are engineered, robust affinity proteins, which are much smaller than traditionally-used antibodies, and can afford significant surface functionalization without extensively changing the LNP surface. Having already demonstrated targeted uptake of these affibody-LNPs in cells, in this proposal we will quantify the impact of labelling on LNP structure to enable us to understand the relationship between LNP labelling, structure, uptake and function.

title: Stability Test of OAM Generating Neutron Optics

description: Particles such as neutrons can often be better described by spread out waves than by point like particles in quantum mechanics. In the simplest case the wavefronts of these quantum mechanical waves are parallel. Orbital angular momentum (OAM) refers to a special structure imprinted on these waves which results in helical wavefronts. These twisted waves have been observed in acoustics, optics and electrons. In neutron physics claims of twisted wavefronts are still controversial, due to the difficulty in resolving this small structure. We have derived a method by which OAM can be imprinted on the neutron using an electric field. Nonetheless the amount of OAM generated by this method is small. Therefore we propose to determine the stability and sensitivity of the Larmor instrument down to 10^-5 radians, which would be required to effectively measure OAM generation in electric fields.

title: Polyphosphoester Gradient Co-Polymer Micelles as the First Biodegradable Agents for 31P Magnetic Resonance Imaging

description: Magnetic Resonance Imaging is a powerful medical imaging modality that can provide information on anatomic and molecular level without the use of dangerous ionizing radiation. Hot-spot MRI uses different nuclei than proton. This type of MRI turned out highly efficient for applications where quantification of the imaging agent is important, particularly in imaging cardiovascular diseases, cancer and immunotherapies. However, current hot spot agents are non-biodegradable and show major environmental concerns. As a solution, we have developed the first biocompatible and biodegradable imaging agents for hot spot MRI. These agents are based on polymeric colloids. The structure-function relationship is unknown but is crucial for the future application. We will use SANS to study the structural properties of these agents, and correlate them to imaging performance.

title: Using magnetic reference layers to unravel the interaction of proteins with complex lipid bilayers

description: During a previous experiment (RB1710262), we investigated the structure of sponge-like nanoparticles (LNPs) deposited on a silica surface with and without Aspartic protease (Asp, 34KDa), which is a common food additive in cheese manufacturing. We showed that the structure deposited layer changed when the contrast was changed, and we could fit only data collected from a single contrast, which was not sufficient to properly characterize this system. Here we propose to use substrates including a magnetic reference layer composed of iron, with a thick silica cap to protect the metal from the water. The use of these magnetic substrates will enable us to collect polarized data on the LNP layer, without the need to change liquid contrast, while still getting sufficient data to determine the structure.

title: Investigation of magnetic correlations in the S=1/2 coupled trimer compound K2Cu3Ge4O12

description: The interacting S=1/2 trimer compounds are fascinating systems to experimentally study novel quantum phenomena of many body physics in condensed matter and to validate the theoretical proposals. Here, we propose a comprehensive powder neutron diffraction study on K2Cu3Ge4O12, a model interacting spin-1/2 AFM trimer compound, by using the WISH diffractometer to determine the ground state magnetic structure and temperature dependent spin-spin correlations down to 0.25 K. The results of the proposed experiment will shed light on the role of the weak intertrimer couplings (in 2D for K2Cu3Ge4O12) on the magnetic ground state and will be compared with the same for the sister compound Na2Cu3Ge4O12 having 1D interacting trimers. The outcome of the proposed study would be helpful for a validation of the theoretical proposals for the magnetic ground states of S = ½ trimer systems in general.

The experiment was awarded time at ILL (8-02-888) but was not possible due to COVID, before reactor shutdown.

title: Identification of the collapse mechanism of responsive block copolymer brushes for controlled gene delivery

description: Dense polymer brushes have exceptional potential to regulate the sequestration of RNA/DNA materials for high efficiency gene transfection. Polycationic brushes decorating the surface of nanoparticles have promising properties for the stable capture of RNA oligonucleotides and high transfection efficiencies. A new generation of such vectors proposes to use block copolymer brushes to mimic compartmentalised hierarchical virus structures. However, control of responsive block copolymer brushes’ architecture remains poor at the nanoscale. This proposal’s objective is to resolve the thickness-dependent morphological changes (domain/homogenous barrier formation) of amphiphilic block copolymer brushes grown from solid (Si) substrates. It will contribute to the confirmation and refinement of existing computational modelling studies and to the elucidation of their properties for gene delivery.

title: Revealing the impact of the lipid composition on PfEMP1-membrane interactions

description: Cerebral malaria is the most severe neurological complication of the infection by the parasite Plasmodium falciparum. During the blood phase of the infection, which is responsible for the pathology of this disease, the parasites invade red blood cells (erythrocytes). Infected erythrocytes (IEs) express variable surface antigens known as Plasmodium falciparum erythrocyte membrane proteins 1 (PfEMP1). This adherence and accumulation of IEs at endothelial surface causes occlusion of blood vessels in the brain leading to lethal neurological complications. Here we propose NR measurements to investigate the location of two variants of the PfEMP1-A protein family, named HB3-var3 and PFD1235w, on lipid membranes. Our main goal is to shed light on the role played by the membrane lipid composition in favouring adsorption of PfEMP1 proteins on endothelial cell membranes.
