A phenomenological mathematical modelling framework for the degradation of bioresorbable composites
… of biodegradable polyesters and calcium-based ceramics is paramount in order to fully unlock the potential of these materials, which are heavily used in orthopaedic applications and also being considered for stents. A modelling framework which characterises the degradation of bioresorbable …

Improved sol based ceramic moulds for use in investment casting
… and unpredictable, with poor packing of the ceramic constituents leading to a non-uniform porosity network. The structure and distribution of the binder is also established and this indicates that the major load bearing points within the mould consist of thin areas of silica. As such, the …

Investigation of high-performance lithium-ion batteries based on highly conductive Li7La3Zr2O12 solid-state electrolyte and stable electrode-electrolyte interface
… batteries. Chapter 5 reveals the effects of LLZO ceramic filler distribution and doping elements (Al and Bi) on the ambient-temperature ionic conductivity, Li+ transference number, electrochemical stability window, and ability to suppress lithium dendrite growth of poly(vinylidene fluoride) based …

Investigation of polymers used in lithium oxygen batteries as electrolyte and cathode materials
… oxygen batteries. Additionally, the addition of ceramic filler SiO₂ was found to reduce the stability of polymer electrolyte towards oxygen reduction reaction although higher ionic conductivity was obtained. Polyethylene glycol based gel polymer electrolyte without SiO₂ addition exhibited …
