  1. 16. Thermal and Photon Stimulated Reactions on Metal Particles

    Författare :Kristina Wettergren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plasmons; Platinum Clusters; Platinum Nanoparticles; Hydrogen Oxidation; Sodium; Silver Nanoparticles; Nitric Oxide; Photodesorption; Sintering; Graphite; Water;

    Sammanfattning : The interaction between molecules and solid surfaces influence our daily lives in many ways. One important example is heterogeneous catalysis where surface reactions, for example, are used for production of chemicals and exhaust after-treatment. LÄS MER

  3. 17. Defending the university? : Academics’ reactions to managerialism in Norwegian higher education

    Författare :Jo Ese; Ann Bergman; Helge Ramsdal; Ivar Bleiklie; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; CUDOS; higher education; managerialism; academic resistance; academic gaming; Working Life Science; Arbetsvetenskap;

    Sammanfattning : The thesis contributes to the knowledge on academic work in the 21st century, with a special emphasis on how members of faculty react to contemporary developments in the management of universities. The approach is qualitative and consists of 25 in-depth interviews with academics at two higher education institutions in Norway. LÄS MER

  4. 18. Sound intolerance : characteristics, psychosocial work factors and reactions to exposure

    Författare :Johan Paulin; Linus Andersson; Steven Nordin; David Baguley; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sound intolerance; hyperacusis; psychosocial work environment; Noise sensitivity scale; white noise; Ljudintolerans; hyperakusi; psykosocial arbetsmiljö; vitt brus; ljudöverkänslighet; Psychology; psykologi;

    Sammanfattning : Sound intolerance refers to an adverse reaction to sounds at sound pressure levels most people do not find bothersome. It is sometimes associated with hearing loss and tinnitus, but neither conditions are a prerequisite for being intolerant to sounds. LÄS MER

  5. 19. Mechanistic Studies on Ruthenium-Catalyzed Hydrogen Transfer Reactions

    Författare :Jenny B. Åberg; Jan-Erling Bäckvall; Charles P. Casey; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mechanistic studies; catalysis; ruthenium; hydrogen transfer; racemization; transfer hydrogenation; alcohols; ketones; amines; imines; inner-sphere; outer-sphere; solvent cage effect; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : Mechanistic studies on three different ruthenium-based catalysts have been performed. The catalysts have in common that they have been employed in hydrogen transfer reactions involving alcohols and ketones, amines and imines or both. LÄS MER

  7. 20. Surface and Interface Phenomena Studied with Pd Metal-Oxide-semiconductor Structures : Adsorption, catalytic reactions, hydrogen sensing and Pd restructuring

    Författare :Mats Eriksson; Wolfgang Göpel; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The electronic properties of palladium metal-oxide-semiconductor (Pd-MOS) structures are highly sensitive to hydrogen over a large pressure range. Such devices have been found useful in several applications, e.g. as a chemical sensing element in the so called electronic nose. LÄS MER
