Title of Thesis:‘ A Macroscale and Microscale Computational Modelling Study of Sonothrombolysis.’
Sonothrombolysis is a promising treatment strategy that utilises ultrasound to enhance the lysis of blood clots. Recent studies in sonothrombolysis have found that the addition of microbubbles near the clots can increase clot lysis during ultrasound insonation. However, the selection of the right combination of ultrasound and microbubble parameters is difficult due to the wide range of treatment options being available. This research seeks to develop a computational model to understand how the ultrasound and microbubble parameters interact with each other during sonothrombolysis. The information obtained may provide fundamental insight that is crucial in bringing sonothrombolysis closer to clinical implementation.

Title of Thesis:‘ Development of a Self-Biased Photoelectrochemical Tandem System for Sustainable Hydrogen Production.’
As the world confronts the critical need for clean energy, sustainable green hydrogen production emerges as a pivotal solution. Photoelectrochemical( PEC) technology, which harnesses sunlight to drive water-splitting reactions, offers a sustainable green technology alternative. This research successfully developed a PEC tandem system, encompassing the design and optimisation of the photoelectrodes and overall system operation. By integrating materials innovation with system design and refinement, this research successfully developed the self-biased BiVO4-Cu2O PEC tandem system, achieving enhanced water-splitting performance. The outcomes of this research serve as a foundation for future advancements in PEC water-splitting, accelerating progress toward a carbon-neutral energy future.

Title of Thesis:‘ Modeling Multiscale Enzymatic Hydrolysis of Cellulose: Coupled Population Balances for Bridging the Particle and Polymer Scales.’
Enzymatic hydrolysis of cellulose has long been the subject of scientific inquiry, owing to its potential to produce fermentable sugars for biofuel production and other high-value products. Yet, the process remains fraught with scientific challenges due to its inherent multiscale complexity. This thesis develops a new modeling framework that couples the key mechanisms operating across multiple scales of the process by using population balances. The insight into the rate-limiting mechanism and multiscale dynamics of the process gained from the model will be invaluable in achieving precise control of the system.
