17. Long-term phosphorus supply in agricultural soils : size and dynamics of fast- and slow-desorbing phosphorus pools
Abstract : To improve phosphorus (P) fertiliser management, a better understanding of inorganic P exchange between the soil solution and solid phase is needed. This thesis examined the dynamics of this exchange, distinguishing between pools of P that are fast- and slowdesorbing, and compared methods for quantification of these pools. READ MORE

18. Computational Studies of Hydrogen Storage Materials : Physisorbed and Chemisorbed Systems
Abstract : This thesis deals with first-principles calculations based on density functional theory to investigate hydrogen storage related properties in various high-surface area materials and the ground state crystal structures in alkaline earth dicarbide systems. High-surface area materials have been shown to be very promising for hydrogen storage applications owing to them containing numerous hydrogen adsorption sites and good kinetics for adsorption/desorption.

20. Multimodal Chemical Imaging of Amyloid Plaque Pathology in Alzheimer’s Disease
Abstract : Alzheimer’s disease (AD) is the most common form of dementia. AD has been linked to the aggregation of amyloid beta (Aβ) peptides into extracellular deposits, Aβ plaques. These are also found in cognitively unimpaired amyloid-positive (CU-AP) individuals, but these Aβ plaques are primarily diffuse in structure. READ MORE
