In-operando techniques for early-stage corrosion
In this thesis, novel experimental approaches are investigated to study corrosion at the solid/liquid interface, at a higher spatial and temporal resolution than previously possible. Corrosion remains a pernicious concern for metallic structure stability. This is evident in the common case steel in …

A Study of Novel Nitrogen-Containing Quinoidal Electrolytes for Redox Flow Batteries
… with their decoupled power and capacity scaling are a promising energy storage technology. However, low energy density and high capital costs stymy such systems. For this reason, novel electrolytes are under active development. Previous electrolytes have involved a variety of metal-containing …

Thermal Evolution of MAS, YSZ and GZO Thermal Barrier Coating Materials in Benign and CMAS Rich Environments
Abradable thermal barrier coatings (TBCs) play a crucial role as thermal insulators and dynamic seals in turbine engines. However, the conventional choice, yttria-stabilised zirconia (YSZ), exhibits vulnerabilities, such as sintering induced stiffening, phase transformations, and susceptibility to …

Utilising Boron containing Lewis Acid Functions as "Stores" for Hydride and Other functional groups and its impact on Catalytic Reactions
… metal mediated reactions play a vital role in the catalysis of many chemical transformations. Whilst most of these transformations occur at the metal centre, with ligands acting as spectators, new systems incorporating the direct involvement of coordinated ligands within catalytic cycles are …

Deformation at Low Temperatures in Single Crystal Ni-base Superalloys
The development of single crystal Ni-base superalloys for gas turbine applications has focused on creep behaviour in the high-temperature regime (above 700 °C). However, the study of deformation in the range of 20 °C to 700 °C is critical to understanding behaviour in the shanks of turbine blades …

Phase and structural changes of nickel catalysts as a function of reaction conditions
… hydrogen and carbon dioxide, which has attracted increased attention in recent times. It provides a means for both energy storage through substitute natural gas (SNG) production and as a process for the conversion of carbon dioxide into valuable products. Ni is the most widely used metal for SNG …

On in-situ methodologies for the characterisation and simulation of vibro-acoustic assemblies
A drive towards leaner engineering has seen the use of physical prototypes become a limiting factor in the development of new products. Consequently, alternative prototyping methods are of interest. With their ability to reduce cost, accelerate time to market, and optimize products to higher levels …
