    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Battery; Carbon; Electrochemical; Electrodeposition; Emulsion; Energy; Exfoliation; Foam; Lithium; Microbattery; Multifunctional; Nanoparticles; Polyaniline; Polymer; Power; Sol-gel; Storage; Structured; Three-dimensional; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : Carbon foams are among the existing electrode designs proposed for use in 3D Li-ion microbatteries. For such electrodes to find applications in practical microbatteries, however, their void sizes, specific surface areas and pore volumes need be optimized. READ MORE

  4. 2. Immobilisation of Ru-Based Molecular Catalysts for Electrochemical Water Oxidation

    Author : Andrew Howe; Sascha Ott; Javier Concepcion; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular Catalysis; Metal-Organic Frameworks; Water Oxidation; Post-Synthetic Exchange; Electro-chemistry.; Kemi; Chemistry; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : Artificial photosynthesis requires catalysts for efficient and selective conversions of small molecules. Molecular catalysts are advantageous to use in these instances as they offer precise control over chemical reactivity. READ MORE

  5. 3. Structure and Properties Investigations of the La2Co1+z(Ti1-xMgx)1-zO6 Perovskite System

    Abstract : Perovskite based materials have great potentials for various energy applications and the search for new materials for uses in SOFCs has largely been concentrated to this class of compounds. In this search, we have studied perovskite phases in the system La2Co1+z(Ti1-xMgx)1-zO6, with 0  x 0.9 and z = 0.0, 0. READ MORE

  6. 4. Design of carbide-based nanocomposite coatings

    Author : Erik Lewin; Ulf Jansson; Jörg Patscheider; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; chemistry; thin film; dc magnetron sputtering; carbide; nanocomposite; PVD; solid solution; Chemistry; Kemi; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; Oorganisk kemi;

    Abstract : In this thesis research on synthesis, microstructure and properties of carbide-based coatings is reported. These coatings are electrically conducting, and can be tailored for high hardness, low friction and wear, along with load-adaptive behaviour. Tailoring these properties is achieved by controlling the relative phase content of the material. READ MORE

  7. 5. Open-framework Structures Built by Inorganic Clusters : Synthesis and Characterization

    Author : Hong Chen; Junliang Sun; Xiaodong Zou; Thomas E Albrecht-Schmitt; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Open-framework; germanates; vanadoborates; aluminoborates; germanosilicates; crystal structure; hydrothermal synthesis; crystal X-ray diffraction; rotation electron diffraction; powder X-ray diffraction; Inorganic Chemistry; oorganisk kemi;

    Abstract : Novel open-framework germanates and vanadoborates, which are constructed from typical types of clusters, have been synthesized based on different strategies. The crystal structures are solved by using single crystal X-ray diffraction (SXRD) technique or by combined techniques. READ MORE
