  2. 1. Electrochemical Deposition of Nanostructured Metal/Metal-Oxide Coatings

    Author : Jonas Eskhult; Leif Nyholm; Jan-Otto Carlsson; Jay Switzer; Uppsala universitet; []
    Keywords : Inorganic chemistry; electrochemical deposition; local pH; Cu2O; Sb2O3; complex; EQCM; reduction; Oorganisk kemi;

    Abstract : Electrochemical deposition finds applications in the electronics- and protective coating industries. The technique is a versatile tool for the synthesis of alloys and thin films. Knowledge of the fundamental aspects of the electrode processes enables the design of nanostructured materials. READ MORE

  4. 2. To metal, or not to metal : Diverse mechanisms of O2-activation and radical storage in the ferritin superfamily

    Author : Vivek Srinivas; Martin Högbom; Brian Hoffman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metalloprotein; di-metal; Oxygen activation; Substrate oxidation; Ribonucleotide reductase; Radical; DOPA; ADE-DOT; X-Ray free-electron laser; soluble Methane monooxygenase; Biochemistry; biokemi;

    Abstract : Proteins in the Ferritin-like superfamily are characterized by a four alpha-helical structural motif. These proteins are distributed across all three kingdoms of life and perform a wide range of functions. READ MORE

  5. 3. Surface reactivity of metal nanoparticles : - importance of surface active agents and biomolecules from a transformation, mobility and toxicity perspective

    Author : Sara Skoglund; Inger Odnevall Wallinder; Lars Österlund; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal nanoparticles; surfactants; metal release; characterization; size distribution; nanotoxicology; risk assessment; Kemi; Chemistry;

    Abstract : Metallic nanoparticles possess unique properties due to their size and are widely used in e.g. consumer products. From this follows a need to identify and assess potential risks of human and environmental exposure. READ MORE

  6. 4. Tribology in Metal Working

    Author : Maria Nilsson; Staffan Jacobson; Mikael Olsson; Magnus Jarl; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; friction; wear; metal working; coatings; wire drawing; hot work rolls; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials; Steel Forming and Surface Engineering;

    Abstract : This thesis focuses on the tribological performance of tool surfaces in two steel working operations, namely wire drawing and hot rolling. In all forming operations dimensions and surface finish of the products are of utmost importance. READ MORE

  7. 5. Transition Metal Hydrides : Biomimetic Studies and Catalytic Applications

    Author : Jesper Ekström; Hans Adolfsson; Jonathan Williams; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transition metals; catalysis; bioinorganic chemistry; hydrides; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

    Abstract : In this thesis, studies of the nature of different transition metal-hydride complexes are described. The first part deals with the enantioswitchable behaviour of rhodium complexes derived from amino acids, applied in asymmetric transfer hydrogenation of ketones. READ MORE
