11. Predator induced phenotypic plasticity in a freshwater snail
Abstract : In this thesis I examined a phenotypically plastic defence in a common freshwater snail, Radix balthica. Adaptive prey defences may involve behavioural, life-history or morphological changes. Snails are important species in freshwater systems. READ MORE

12. A Study of Biomass Combustion Problems and the Selective Catalytic Oxidation of Ammonia
Abstract : Increasing awareness of the need of reducing CO2, NOx and SOx emissions from combustion systems has led to a strong interest in biomass as a fuel source. Using it in combination with fluidised bed combustion technology can lead to a lowering of NOx emissions to the atmosphere. READ MORE

13. Hydrotreatment of lignin and its bio-oils over transition metal sulfide-based supported and unsupported catalysts
Abstract : The scarcity of fossil feedstocks and the deterioration of the current global climate condition have prompted the search for reliable alternatives for fossil fuel replacement. Biomass feedstocks such as lignin can be used to produce renewable bio-oils that can fill the gap left by fossil-derived oils. READ MORE

14. Investigating the parameters that influence the behaviour of natural iron ores during the iron production process
Abstract : In the iron production processes, sinters and pellets are mostly used as raw materials due to their consistency with respect to physical and chemical properties. However, natural iron ores, as mined, are rarely used directly as a feed material for iron processing. READ MORE

15. Poly(phenylene oxide)s functionalized with cationic side chains: design, synthesis and properties as anion exchange membranes
Abstract : Anion exchange membrane fuel cells (AEMFCs) are considered as one of the most important next-generation energy conversion technologies. AEMFCs convert chemical energy into useful electrical energy and have great potential forachieving high conversion efficiencies. READ MORE
