title: W/CO2 microemulsions formed under moderate conditions

description: Water-in-CO2 microemulsions (W/CO2 MEs) are composed of a dense CO2 (liquid or supercritical CO2) continuous medium and dispersed water droplets stabilized by CO2-philic surfactants. Fluorocarbon (FC) chains were thought to be essential components of CO2-philic surfactants. However, many FCs are non-biodegradable environmental pollutants, toxic to life, bioaccumulative and expensive. Recently, we succeeded to form W/CO2 MEs with the tailor-made double trimethylsilyl (TMS)-alkyl-tail nonionic surfactant and a trace level of a short FC-tail surfactant as a cosurfactant: this system was stable at an easily accessible pressure of 55 bar and temperature of 15 ºC (RB2410068). This new experiment will explore formation of high water-content W/CO2 MEs at moderate P-T conditions with optimized FC-free surfactant structures and compositions. Such easily-accessible and green W/CO2 MEs could offer important practical benefits in terms of safety, low cost, and ease of processing.

title: Understanding the Interface between Electrolytes and Transition Metal Fluoride Cathodes

description: We request 4 days on NIMROD to determine the structure of LiFSI in N-propyl-N-methylpyrrolidinium bis(fluorosulfonyl)imide (Pyr1,3 FSI) ionic liquid electrolyte at the interface with transition metal fluoride (TMF) conversion cathodes (FeF2 and CuF2). The absence of practical cost-effective high-energy density cathodes is currently hindering the advancement of battery storage capacity. TMF conversion cathodes can potentially fill this void possessing a substantially higher capacity at a lower cost compared to current intercalation cathodes. However, a limited cycling stability have impeded their practical use so far, with origins tied to the interface between the liquid electrolyte and the cathode. Here, we aim to investigate the solvent and ion structuring at the interface between the electrolyte and the FeF2 and CuF2 cathode nanorods, before and after cycling, to determine the molecular interactions involved in degradation mechanisms.

title: Highly Efficient Production of H2 through Methanol Reforming

description: Production of hydrogen (H2) is an important task for clean energy. We designed a novel catalyst for efficient H2 production through methanol-water reforming. By tuning of the amount of Pt metal species and reducible Re oxide on the surface of reactive γ-Mo2N support, we have shifted the reaction from a competitive adsorption/activation model in typical supported metal catalysts to a non-competitive mechanism, synergistically resulting in enhanced catalytic turnover rates. We request 5 days on MAPS to study the binding dynamics of methanol, water and intermediates over the exceptional catalyst (2Pt-2Re/γ-Mo2N). The proposed study will investigate the vibrational spectroscopy of the catalyst, adsorption of methanol and H2O molecules and any possible reaction intermediates on active sites. This study aims to reveal the role of Pt and ReOx sites in adsorption and activation of reactant molecules, giving key insights into the efficient H2 production.

title: Interaction of non-lamellar liquid-crystalline lipid carpets with model endosomal vesicles.

description: Nucleic acid (NA) therapeutics hold great potential, but their success relies on delivery systems, able to promote effective endosomal
escape. Emerging evidence suggests that non-lamellar lipid nanoparticles (NLLNPs), with highly curved bilayers, may enhance
endosomal escape. We have developed a microfluidic technique to produce NLLNPs using glycerol monooleate and ionizable lipids,
which combine topological activity with pH sensitivity. Preliminary studies show these NLLNPs effectively bind to and destabilize
endosomal membranes under acidic conditions, but the mechanism remains unclear. We propose to use Neutron Reflectometry (NR) to
investigate the mechanism by which NLLNPs destabilize endosomal membranes as a function of pH. To this end, we will employ
innovative solid-supported nanometric “carpets” of NLLNPs and study their interactions with model endosomal vesicles in real-time
using Time-Resolved NR. Leveraging selective deuteration and contrast variation, we aim to resolve structural changes and lipid
exchange processes occurring during vesicle binding and fusion with NLLNPs. These insights will inform the design of more efficient
lipid nanoparticles for NA delivery.

title: Investigation of the crossover between spin orbit and hyperfine driven electron spin relaxation

description: Organic semiconductors (OSCs) are enabling flexible, large-area optoelectronic devices, such as organic light-emitting diodes (OLEDs), transistors and solar cells. OSCs can be simple to process, stable and non-toxic, and the variety of possible molecular designs is enormous. Due to their long spin lifetimes, carbon-based materials could also have an impact on spintronics. Both spin orbit (SO) interaction and hyperfine (HF) interaction have been used separately to explain the magnetoresistance and spin diffusion length in spin valves of the same organic material. It is therefore very important to understand the mechanisms of spin relaxation in OSCs. Here, we propose to use muons to directly probe the crossover between SO and HF, and compare the results directly to g-shifts in electron paramagnetic resonance and theoretical models.

title: Neutron diffraction studies of separation of olefins and paraffins in novel bimetallic MOFs

description: The global polymer market is dominated by lower olefins, which are the most demanded chemicals. Polymer-grade (&gt;99.95%) olefins are required to product high quality polymers. However, the coexistence of olefin and paraffin with similar physical properties in the crude product makes them extremely challenging to separate. Leading technology relies heavily on cryogenic separation, which is extremely energy-intensive. We have recently developed 3 novel ultramicroporous robust metal-organic frameworks (MOFs), namely Al/Cu-Pyc, Ga/Cu-Pyc, and In/Cu-Pyc, which show great promise for their separation in the mixtures. To gain key structural insights into their exceptional adsorption performance, we request 4 days on WISH to investigate the binding domains of deuterated C2 and C3 hydrocarbons within these materials via in situ neutron powder diffraction (NPD). This study will promote the development of low-carbon purification of alkene from alkane.

title: Effect of layer stacking and cooling conditions on residual stress distribution in wire arc additive manufactured duplex stainless steel

description: This proposal aims to use neutron diffraction for the investigation of residual stresses in a duplex stainless steel induced by Wire Arc Additive Manufacturing (WAAM) process enhanced by a cooling system. The study will focus on an important issue such as: the control of microstructure, the reduction of residual stresses through cooling strategies and finally, the relationships between layers stacking, cooling conditions and residual stress distribution. Neutron diffraction will be used to analyze the residual stress gradients. The collected data will contribute to quantifying the impact of number of the deposed layers, the cooling conditions on the metallurgical and mechanical behaviors of the built parts. The stresses obtained in this work will also serve as essential data to validate a concurrently developed thermomechanical Finite Elements model of the produced parts. The ultimate goal is to enhance the understanding and the control of the WAAM process to improve the component’s production.

title: Hydrophobic deep eutectic solvents for the recovery of gallium from zinc mine tailings

description: Global demand for gallium is rapidly increasing, due to its applications in electronic devices. Challenges in gallium supply are caused by the lack of gallium ore; this metal is recovered as a secondary element from mine tailings of other metal industries, chiefly aluminium, although recovery from zinc mine tailings is also possible. 90% of UK's gallium supply comes from China, 8% from Russia and only 2% from UK, posing a serious threat to the supply chain. While China and Russia use aluminium tailings to produce gallium, secure supply for the UK/EU markets would be best served by leveraging on UK/EU zinc mines.
Our group developed a family of hydrophobic DES based on a metal-extracting agent, trioctylphosphine oxide (TOPO), some of them efficient in selective separation of very dilute gallium from the zinc leachate (waste from zinc mining). The best performance was achieved with DES comprised of TOPO and malonic acid, in contrast to a very similar formulation of TOPO and levulinic acid. 
Here, we propose the study of these two hydrophobic DES formulations based on TOPO, with and without gallium chloride, in order to understand the difference between the structure of the two DES, and its influence on the mechanism governing selective separation.

title: Understanding high piezoelectricity in the lead-free relaxor ferroelectric BFBT

description: Lead free relaxor ferroelectrics are being developed to replace lead-based systems which are widely used commercially in capacitors, actuators and sensors. An important aspect of these materials is their piezoelectric behaviour which can be utilised in advanced electromechanical devices. Such relaxor ferroelectrics are characterised by local polar nano regions (PNRs) which show fast switching in electric fields. Classical average structure analysis cannot explain the observed piezo/ferroelectric behaviour of these materials and a more comprehensive analysis of both long-range and short-range structure is needed. It is proposed to carry out a detailed study of the local and long range structures of the lead-free relaxor ferroelectric (1-x)BiFeO3-xBaTiO3 (BFBT) using reverse Monte Carlo analysis of neutron total scattering data. At around x = 0.33, the system shows outstanding piezoelectric performance. This study aims at studying the evolution of PNRs in this system and their role in the enhanced piezoelectric behaviour. The study would represent the first of its kind on a lead-free ferroelectric.
