1. Catalytic conversion of syngas to higher alcohols over MoS2-based catalysts
Abstract : The present thesis concerns catalytic conversion of syngas (H2+ CO) into a blend of methanol and higher alcohols, an attractive way of producing fuels and chemicals. This route has the potential to reduce the oil dependence in the transport sector and, with the use of biomass for the syngas generation, produce CO2-neutral fuels. READ MORE

2. Catalytic conversion of LignoBoost Kraft lignin into liquid products in near-critical water
Abstract : Lignin, one of the three main components of lignocellulosic biomass, is the second most abundant organic polymer found on Earth. Due to its aromatic nature, lignin is recognized as being a potential feedstock for producing transportation fuel and high value-added chemicals. READ MORE

3. Fuel conversion and ash formation interactions : a thermochemical study on lignocellulosic biomass
Abstract : Biomass is considered to be CO2 neutral, and to be able to reduce the dependency on fossil fuels the need for expanded and sustainable biomass feedstock is increasing. Ash-related problems are some of the most important aspects of this increasing use of new biomass assortments in thermal energy conversion systems. READ MORE

4. Components based on optical fibers with internal electrodes
Abstract : The topic of this thesis is development ofdevices fortelecom applications based on poled optical fibers. The focusis on two different specific functions, wavelength conversionand optical switching.Optical switching is demonstrated in a poled optical fiberat telecom wavelengths (~1.55 mm). READ MORE

5. Proton pathways in energy conversion : K-pathway analogs in O2- and NO-reductases
Abstract : Oxygen and nitric oxide reductases are enzymes found in aerobic and anaerobic respiration, respectively. Both enzyme groups belong to the superfamily of Heme-Copper Oxidases, which is further divided into several subgroups: oxygen-reducing enzymes into A-, B- and C-type and nitric oxide reductases into qNORs and cNORs.
