  2. 16. Surface-Induced Modification of Supported Late Transition Metal Complexes

    Author : Olesia Snezhkova; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; N-heterocyclic carbene palladium complexes; X-ray photoelectron spectroscopy; electron charge transfer; iron phthalocyanine; catalysis; X-ray absorption spectroscopy;

    Abstract : The work presented in this thesis addresses the investigation of the electronic, magnetic, and structural properties of late transition metal complexes supported on various surfaces. The research is aimed at studying the interaction between the molecules and the support, together with the intermolecular interaction. This knowledge is essential e.g. READ MORE

  4. 17. A thermostable alkaline protease from a new alkaliphilic Nesterenkonia sp

    Author : Shahrzad Bakhtiar; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; substrate specificity; crystallization; Biotechnology; Bioteknik; DNA-DNA hybridisation; 16S rDNA analysis; phenotypic characterisation; circular dichroism; differential scanning calorimetry; Nesterenkonia abyssinica; stability; calcium-independent; alkaline protease; alkaliphilic;

    Abstract : This thesis concerns a novel alkaline protease produced by an extremophilic microbial specie, designated as AL20, isolated from a feather sample collected at the shore of the alkaline soda lake Abjata in the Ethiopian Rift Valley. The isolate is a heterotrophic, alkaliphilic, halotolerant gram-positive, strictly aerobic, non-motile, non-spore forming bacterium. READ MORE

  5. 18. Release to the Gas Phase of Potassium, Chlorine, and Sulfur from Biomass Fuels under Dual Fluidized Bed Gasification Conditions

    Author : Placid Tchoffor Atongka; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The transformation and release of ash-forming elements during the thermal conversion of biomass are conducive to ash-related problems, for example, agglomeration of the bed material in fluidized beds. The occurrence and severity of ash-related problems largely depend on the extents to which potassium (K), chlorine (Cl), and sulfur (S) are released from biomass fuels to the gas phase during thermal conversion processes.

  6. 19. Studies of Volcanic Plumes with Spectroscopic Remote Sensing Techniques

    Author : Santiago Arellano; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Remote Sensing; FTIR; DOAS; Volcanic gas emissions;

    Abstract : Volcanism is a widespread phenomenon on Earth and other planetary bodies. Terrestrial volcanoes are shallow manifestations of deep and complex mechanisms of heat and mass transport and play an important role in the formation and change of the atmosphere and the natural landscape.

  7. 20. Liquid crystalline polymers for nonlinear optics : pyroelectric polymers and ferroelectric dendrimers

    Author : Jonas Örtegren; KTH; []
    Keywords : ;

    Abstract : This thesis deals with liquid crystalline materialsincluding monomers, side-chain polymers, crosslinked polymers,and dendrimers. The materials are pyroelectric, meaning thatthere is a macroscopic electric polarization in the material,which is energetically stable in the absence of externalfields. READ MORE
