title: Using time-of-flight SESANS to study small volumes of deuterated milk

description: Casein is the structure-forming protein in milk that is present as self-assembled protein colloids, called micelles; casein micelles are the location of calcium in milk. To study either the whole colloid or interparticle interactions, scattering sensitive to large length scales must be used. Spin-echo SANS (SESANS) is the focus of this proposal; it has advantages for studying food colloids (non-destructive, tolerant of multiple scattering, and real-space scattering data). Existing SESANS data from casein micelles in deuterated milk required a large volume of sample to obtain acceptable signal-to-noise (18 mm!). Preliminary ToF SESANS measurements on LARMOR showed that it can be used to obtain SESANS data using much less material. This suggests that time-of-flight SESANS should be a useful technique for studying relatively weakly scattering samples (weak, for SESANS, at least) using small volumes of samples.

title: Disordered Materials Xpress: Solvation of Negatively Charged Carbon Nanotube in DMF

description: Carbon nanotubes have superlative mechanical and opto-electronic. The solvation of these species in polar aprotic solvents gives us the prototypical system for studying the behaviour of the solvent and the competitive surface-solvent-counterion interactions at the charged nano-interface versus the behaviour in the bulk. Data analysis from previous experiments performed on NIMROD on sodium nanotubide in DMF (RB 1610416), DMAc and NMP (RB 1910503) show very promising results which will provide a greater understanding of these systems. As we know that data can be fitted in EPSR and believing that our findings are promising, we ask to be able to repeat the experiment in DMF.

title: Sensory Lipid Membrane Films with Integrated Ion Transporters

description: This study focuses on lipid bilayers resembling cell membranes, integrating ion transporters to capture specific solution-phase ions. Non-Faradaic capacitance spectroscopy is used to analyze ion-specific changes and hydration. The research involves lipid films composed of standard lipid (POPC), thiol-functionalized lipid (DPPTE), cholesterol, and transporters, formed on gold surfaces.
Previous work successfully integrated cation and anion transporters into vesicle bilayers, enabling the flux of specific anions and their hydration shells. Electrochemical Impedance Spectroscopy (EIS) is employed to study ion and water flux in electrode-supported bilayer films.
The study aims to determine bilayer structure, homogeneity, and surface properties. There is a particular focus on elucidating the confined water layer at the gold interface, considering lipid thiolation and ion transporter integration. Additionally, the proposed research examines how electrode potential affects interfacial water presence and ion flux.
Experimental plans include analysing various bilayer samples with different salt concentrations and using neutron reflectometry. The findings will enhance our understanding of biological membranes with integrated ion transporters, with potential applications in biosensing and biophysics.

title: Characterization of Cellulose based-nanodiamond composite for energy storage and electronic applications

description: In the context of environmentally friendly energy storage devices, efforts have been made in the last decade to use green materials for their development. We recently designed a cellulose-based device, using a copy paper substrate, poly(3,4-ethylenedioxythiophene) polystyrene sulfonate electrode and a composite based on detonation nanodiamonds (DNDs) and hydroxypropyl cellulose (HPC) as both solid-state electrolyte and separator. While at a bulk level we observed a one order of magnitude increase in conductivity with the addition of small quantities (1%w) of DND, this increase is far from understood from a molecular perspective; despite a hypothesis that the DND inclusions change chain mobility in the polymeric matrix thus allowing increased ion diffusion. Quasi-Elastic Neutron Scattering (QENS) is a proven experimental method with which to investigate and better understand the influence of nanoparticles on polymer network dynamics at the nanometre and pico-second. We believe direct observation of changes in chain mobility as a function of nanoparticle concentration will help us better understand the impact of the detonation nanodiamonds on the observed bulk conductivity enhancement. We therefore ask for 2 days access to the QENS spectrometer, IRIS, to study the influence of DNDs inclusions on cellulose dynamics at a local level.

title: CsNiCrF6: a potential quantum spin liquid observed by the muon’s additional decoherence due to multiple Coulomb phases?

description: CsNiCrF6 is a material which exhibits multiple Coulomb phases: spin ice, charge ice, and displacement ice. We have previously carried out an investigation on this experiment with MuSR in Cycle 23/3, and we found evidence of an F--µ--F oscillation which is heavily damped, and we expect the origin of this damping to be due to the dynamics in the electronic moments. We attempted to decouple the electronic dynamics by applying a series of longitudinal fields, but we could not do this with MuSR. Therefore, we wish to run the sample on HiFi to attempt to decouple the dynamics and observe the way in which the muon-spin relaxation rate changes.

title: Structural Phase Transitions in Han Blue (Effenbergerite) BaCuSi4O10

description: Han Blue, BaCuSi4O10, a pigment first created in the Western Zhou period ~1200 BCE, has been shown to exhibit two structural phase transitions at low temperature, 87 K and 130 K, which are manifested as discontinuities in the axial thermal expansion coefficients and anomalies in the heat capacity. At ambient temperature in the gillespite-structured phase, Han Blue is found to have an extremely low Grueneisen constant of 0.10. These observations are unexpected and are in disagreement with earlier work we have carried out at ISIS on the gillespite-structured phase Ba0.5Sr0.5CuSi4O10 in which no structural phase transitions are observed below room temperature, or at high temperature up to 1073 K. Furthermore, we find a low valued, but significantly larger Grueneisen constant of 0.45. We propose to carry out a crystallographic study of these structural phase transitions in the end-member phase Han Blue characterising the crystal structures of the two new phases but also measuring the evolution of the unit cells to shed more light on the nature of the transitions themselves.

title: Understanding Barocaloric Effects in Soft Organic Salts

description: More than 20% of the world’s electricity is used for cooling. Current cooling technologies, however, rely on potent greenhouse gases to serve as refrigerants. Replacing these refrigerants with solid-state materials provides a sustainable alternative to conventional cooling technologies. This approach—referred to as solid-state barocaloric cooling—has the potential to provide cooling with zero direct emissions. However, there is currently a substantial lack of fundamental knowledge about barocaloric materials, and efforts to investigate the microscopic mechanisms for barocaloric effects are in their infancy. Here, we propose quasi-elastic neutron scattering studies on dialkylammonium halide salts, which are a novel class of barocaloric materials recently identified by my research group. This project aims to probe dynamics to reveal the molecular origin of their large barocaloric effects.

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.
