  2. 1. Nickel and iridium pincer complexes with saturated frameworks - synthesis and reactivity

    Author : Klara Jonasson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PCP complexes; aliphatic pincer ligands; coordination; cyclometallation; iridium; nickel; organometallic synthesis; CO2 activation; catalysis;

    Abstract : As the tridentate chelate complexes referred to as pincer complexes have expanded their scope as homogeneous catalysts, there is an increased interest in electronic and steric fine-tuning of such complexes. One accessible variable in this aspect is the hybridisation of any coordinated carbon atoms. READ MORE

  4. 2. Open-Framework Germanates and Nickel Germanates : Synthesis and Characterization

    Author : Shiliang Huang; Junliang Sun; Xiaodong Zou; Hermann Gies; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; open-framework; zeolites; germanates; nickel germanates; structure directing agent; nickel complexes; crystal structure determination; hydrothermal synthesis; Structural Chemistry; strukturkemi;

    Abstract : Microporous materials have a wide range of important applications in separation, gas adsorption, ion-exchange and catalysis. Open-framework germanates are a family of microporous compounds and are of particular interest. READ MORE

  5. 3. Chemical Speciation of Sulfur and Metals in Biogas Reactors : Implications for Cobalt and Nickel Bio-uptake Processes

    Author : Sepehr Shakeri Yekta; Bo Svensson; Ulf Skyllberg; Åsa Danielsson; Charles Banks; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; Anaerobic digestion; Chemical speciation; bio-uptake; Sulfur; Iron; Cobalt; Nickel; Biogas; Anaerob nedbrytning; Kemisk speciering; Bio-upptag; Svavel; Järn; Kobolt; Nickel;

    Abstract : A balanced supply of micronutrients, including metals such as iron (Fe), cobalt (Co), and nickel (Ni), is required for the efficient and stable production of biogas. During biogas formation, the uptake of micronutrient metals by microorganisms is controlled by a complex network of biological and chemical reactions, in which reduced sulfur (S) compounds play a central role.

  6. 4. Unsymmetric PCN Pincer Palladium and Nickel Complexes : Synthesis, Characterization and Reactivity

    Author : Abdelrazek Mousa; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Unsymmetric PCN; Palladium; Nickel; Cyclometallation; Carboxylation; Cross-coupling;

    Abstract : New palladium and nickel complexes based on unsymmetric PCN pincer ligands have been synthesized and fully characterized using different techniques. The substituents on the nitrogen side arm of the ligand have great influence on the cyclometallation and the reactivity of the new complexes particularly in case of nickel. READ MORE

  7. 5. Catalytic and Electrocatalytic Transformations with Palladium and Nickel : Scope and mechanistic investigations

    Author : Alejandro Valiente Sánchez; Belén Martín-Matute; King Kuok (Mimi) Hii; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; Heterogeneous Catalysis; Metal-organic frameworks; Nickel; Palladium; Electrocatalysis; Cross-coupling; Hydrogenation; organisk kemi; Organic Chemistry;

    Abstract : The work presented in this thesis is based on methodology development and mechanistic investigations using heterogeneous palladium and nickel catalysts. Following the introduction (Chapter 1), Chapter 2 presents a summary of the synthesis and characterization of the MOF-supported Pd catalysts (Pd @ MOF) that are used in this thesis. READ MORE
