6. MECHANISMS OF ENHANCED ACTIVITY OF MODEL TiO2/CARBON and TiO2/METAL NANOCOMPOSITE PHOTOCATALYSTS
Abstract : TiO2 is the most widely used photocatalyst for energy and environmental applications because of its outstanding physical and chemical properties. However, the quantum efficiency of TiO2 is greatly diminished by fast electron-hole pairs recombination and light absorption only in the UV region. READ MORE

7. Tunable photonic crystals based on carbon nanofibers
Abstract : Photonic crystals are materials with periodically varying refractive indices. In conventional photonic crystal design it is hard to achieve tunable structures in the visible range, i.e. structures with changeable optical properties. READ MORE

8. Natural and human-induced carbon storage variability in seagrass meadows
Abstract : Seagrasses are considered highly important CO2 sinks, with the capacity to store substantial quantities of organic carbon in the living biomass and sediments, and thereby acting as a buffer against climate change. In this thesis, I have studied carbon storage variability in temperate and tropical seagrass habitats and identified factors influencing this variation. READ MORE

9. The hidden half of the meadow : Interactions between drought, soil carbon, roots and soil microbial communities
Abstract : Soil is a hidden ecosystem which harbours plant roots and countless microorganisms, vital for sustaining life aboveground. These belowground communities provide essential ecosystem services like soil stabilisation and organic matter decomposition. READ MORE

10. Effects of solar radiation on the abiotic and bacterially mediated carbon flux in aquatic ecosystems
Abstract : In this Thesis, I studied some of the current aspects of organic matter photochemistry. I analyzed abiotic phototransformations of several types of dissolved (DOM) and particulate organic matter (POM). I also evaluated the effects of phototransformation of several types of DOM on bacteria. READ MORE
