This PhD project will investigate the mechanical behaviour of steel and aluminium alloys at cryogenic temperatures through experiments performed using neutron beam diffractometry with the SALSA strain diffractometer at the Institut Laue-Langevin (ILL). The aim is to correlate macroscopic stress–strain behaviour with lattice-scale strain evolution, providing new insights into deformation...

LiNiO₂ (LNO) offers the highest theoretical capacity (275 mAh g⁻¹) among layered cathodes but suffers from coupled structural and electronic instabilities at high voltage. We investigate Ti⁴⁺/Sb⁵⁺ co-doping, where Ti⁴⁺ serves as a bulk lattice modifier and Sb⁵⁺ as an interface architect due to their different charge mismatch with Ni³⁺. Cross-sectional SEM shows Sb-driven radial grain alignment...

Fuel cells are important part of the transition from fossil fuels to renewable alternatives, such as hydrogen. The performance and durability of proton exchange membrane fuel cells are strongly governed by the microstructure of the catalyst layer, which in turn is determined by the properties and processing of the catalyst ink. My work focuses on understanding how ink formulation and rheology...

Understanding the degradation mechanisms of protective coatings used in nuclear fuel rods is critical for ensuring their long-term safety and performance under extreme environments. Under normal operational conditions, the fuel rods are exposed to temperatures of ~300 °C in water of high pressure (7 MPa). Even more critical is the event of a loss-of-coolant accident (LOCA) when the temperature...

CsPb₂Br₅ is a low-dimensional metal halide perovskite whose optoelectronic performance is strongly influenced by its lattice dynamics. To probe its vibrational behavior beyond the limits of optical spectroscopy, we performed inelastic neutron scattering (INS) measurements using the MERLIN time-of-flight spectrometer at the ISIS Neutron and Muon Source. At low temperatures (10–100 K), CsPb₂Br₅...

Lattice dynamics play a central role in determining the optoelectronic performance and stability of metal halide perovskites. In lead-free vacancy-ordered Cs₂SnBr₆, understanding phonon behavior and electron–phonon interactions is essential for assessing its suitability for durable optoelectronic applications. Here, we investigate the vibrational properties of Cs₂SnBr₆ using inelastic neutron...

Layered 3d transition-metal oxides LiMO₂ (M = Ni, Mn, Co) are archetypical positive-electrode materials for Li-ion batteries. During electrochemical cycling, Li⁺ deintercalation and accompanying redox reactions generate pronounced stoichiometric gradients between the surface and bulk. Probing the associated evolution of the electronic structure within the first ~20 nm of these materials...

Innovative strategies to tailor the structure and architecture of nanocellulose-based films are needed to enhance their performance regarding mechanical and optical properties for sustainable applications in bioengineering, sensors, and advanced materials. Both cellulose nanofibers (CNFs) and cellulose nanocrystals (CNCs) self-assemble into liquid crystalline phases with nematic and chiral...

The diffusion of H2 in porous materials is important for applications such as H2 storage by physisorption, H2/D2 separation and heterogeneous catalysis [1]. Developing better materials for these applications requires a detailed understanding of how H2 diffuses in carbon materials with different porous and graphenic structures.

The natural mineral clinoatacamite, [Cu2Cl(OH)3], exhibits low-temperature, frustrated magnetic behaviour where competing interactions are responsible for novel magnetic properties. Attempts to establish the magnetic phases in this material have been undertaken and an unconventional applied field (H||b) phase diagram has been revealed [1]. Two critical transition temperatures at zero field...

Solid-state batteries have attracted significant attention as a possible next-generation electrochemical energy storage, with the high energy density of alkali-metal anodes and improved safety of solid electrolytes over conventional liquid electrolytes. However, the advancement of this technology is limited by complex electro-chemo-mechanical evolution at the interface between the alkali-metal...
