16. Dissolved organic carbon in tropical watersheds : Linking field observation and eco-hydrological modelling
Abstract : Dissolved organic carbon (DOC) is a general description of the organic material dissolved in water. DOC is an important source of energy, carbon, and nutrient transfers from terrestrial to aquatic ecosystems. The export of DOC into aquatic ecosystems may contribute to the carbon balance of terrestrial ecosystems and to water degradation. READ MORE

17. Atomic Scale Modelling in Photoelectrocatalysis : Towards the Development of Efficient Materials for Solar Fuel Production
Abstract : Using sunlight to produce valuable chemicals has been pointed out as an interesting alternative to deal with the well-known environmental problem related to the use of fossil fuels for energy generation. Thus, it is crucial for this field the development of novel photocatalysts that could drive the uphill reactions with high efficiency while presenting low price and toxicity. READ MORE

18. InAs Nanowire Devices and Circuits
Abstract : Since the introduction of the transistor and the integrated circuit, the semiconductor industry has developed at a remarkable pace. By continuously fabricating smaller and faster transistors, it has been possible to maintain an exponential increase in performance, a phenomenon famously described by Moore’s Law. READ MORE

19. Modelling and Simulation of Electro-catalysts for Green Energy : From Solvated Complexes to Solid-Liquid Interfaces
Abstract : In this thesis, I have worked with solid-liquid interfaces, adsorbed molecules on the surface, and solvated complexes using Density Functional Theory (DFT) calculations to find possible signatures that could help design suitable energy materials. More specifically, I have explored hybrid electrocatalysts for hydrogen evolution reaction (HER), XPS fingerprints of gas-phase melamine (monomer, dimer, trimer, and hexagonal packed arrangement), hexagonally packed melamine adsorbed on the Au(111) surface, and high-valence Ruthenium complexes along a reaction pathway in aqueous solution through a joint theory-experiment approach.

20. Hydrological Modelling, Topographical Influence and Yield Mapping in Precision Agriculture
Abstract : The use of topographical data in hydrological and agricultural applications has increased with GPS data availability and the concept of precision agriculture. This thesis investigates the relationships between topography and in one case simulated soil moisture and in the other case yield. READ MORE
