  1. 6. Organic Synthesis in Nonionic Microemulsions

    Författare :Maria Häger; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organic reaction; phase behaviour; microemulsion; reaction kinetics;

    Sammanfattning : The aim of this work has been to explore the use of microemulsions as reaction media for organic synthesis. Another important aim has been to improve the understanding of the reaction kinetics and the mechanism of the reaction in this type of surfactant system. LÄS MER

  3. 7. Local structure and dynamics of proton and hydride-ion conducting perovskite type oxides

    Författare :Laura Mazzei; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; hydrogen; local coordination; vibrational dynamics; neutron scattering; vibrational spectroscopy; thin films; Perovskite oxides;

    Sammanfattning : Proton and hydride-ion conducting oxides show potential for application in several technological devices, such as solid oxide fuel cells and batteries. However, fundamental properties pertaining to the local structure and conduction mechanisms in these materials are unclear. LÄS MER

  4. 8. On the Influence of Mixing and Scaling-Up in Semi-Batch Reaction Crystallization

    Författare :Marika Torbacke; KTH; []
    Nyckelord :reaction crystallization; precipitation; benzoic acid; macromixing; mesomixing; micromixing; semi-batch; loop reactor; backmixing; colour experiments; scaling-up;

    Sammanfattning : Semi-batch crystallization experiments have been performedboth in a loop reactor and in stirred tank reactors.Hydrochloric acid was fed to a stirred solution of sodiumbenzoate, and benzoic acid immediately formed. Benzoic acid isformed in excess of the solubility making the solutionsupersaturated.The loop reactor is U-shaped. LÄS MER

  7. 10. Essays on job turnover, productivity and state-local finance

    Författare :Linda Andersson; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; risk-sharing; intergovernmental transfers; international competition; job turnover; local and regional governments; openness; R D; spillover; structural change; taxes; TFP growth; vertical external effects;

    Sammanfattning : This thesis consists of four self-contained papers on job turnover, productivity and state- local finance.Paper [I] deals with the determinants of the rate of job turnover defined as the change in distribution of employment between and within industries in Swedish manufacturing.
