    Sammanfattning : This thesis treats the development of Ion Beam Analysis (IBA) methods, principally for the analysis of light elements at a nuclear microprobe (NMP). The light elements are in this context defined as those with an atomic number Z of less than approximately 13 (aluminium). The work reported is to a large extent based upon multiparameter methods.

  3. 3. Atomistic Modelling of Materials for Clean Energy Applications hydrogen generation, hydrogen storage, and Li-ion battery

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Zhao Qian; Rajeev Ahuja; Börje Johansson; Antonio Ferreira da Silva; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Renewable energy; Materials science; Hydrogen production; Hydrogen storage; Li-ion battery; Density functional theory; SRA - Energy; SRA - Energi; SRA - E-Science SeRC ; SRA - E-vetenskap SeRC ;

    Sammanfattning : In this thesis, a number of clean-energy materials for hydrogen generation, hydrogen storage, and Li-ion battery energy storage applications have been investigated through state-of-the-art density functional theory.As an alternative fuel, hydrogen has been regarded as one of the promising clean energies with the advantage of abundance (generated through water splitting) and pollution-free emission if used in fuel cell systems.

  4. 4. Benefits of Integrated Upgrading of Biofuels in Biorefineries - Systems Analysis

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Eva Ingeborg Elisabeth Andersson; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen; systems analysis; biorefinery; process integration; CO2 emissions; biofuels;

    Sammanfattning : As a result of increasing concerns about climate change, there is considerable current interest in increasing use of CO2-neutral biofuel in the energy system. Increased use of biomass fuel requires that it be upgraded in order to facilitate transportation and distribution to end-users. LÄS MER
