  1. 1. Visualising Functional Nanostructures of Organic Semiconductors using Electron Microscopy

    Författare :Gustav Persson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; transmission electron microscopy; visualisation; clustering; molecular dopant; organic semiconductor; structure-property correlation; nanostructure; 3D; concentra- tion;

    Sammanfattning : Organic semiconducting materials have enabled the solution-processable fabrication of light-weight and flexible electronic devices. In particular, doping using molecular dopants has enabled the fabrication of high-performance organic electronics. LÄS MER

  2. 2. Quantitative equilibrium calculations on systems with relevance to copper smelting and converting

    Författare :Bo Björkman; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Assessment of silicate systems; model for liquid silicates; lead silicates; iron silicates; cuprous silicates; quantitative equi¬librium calculations; emf measurements; Gibbs free energy; cup¬rous sulphide; dicalcium ferrite; wüstite-calcia solid solution; copper smelting and converting;

    Sammanfattning : The present thesis gives a summary of results obtained through theoretical and experimental studies of systems with relevance to copper smelting and converting.Many chemical elements are involved in the copper production pro­cesses and a detailed experimental study would be very time- consuming and expensive.

  3. 3. Methodological aspects on microdialysis sampling and measurements

    Författare :Pernilla Abrahamsson; Ola Winsö; Michael Haney; Anna-Maja Åberg; Urban Ungerstedt; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microdialysis; liver ischemia; heart ischemia; epicardium; liver parenchyma; CMA 600; metabolism; Anaesthetics and intensive care; Anestesiologi och intensivvård; anestesiologi; Anaesthesiology;

    Sammanfattning : Background:     The microdialysis (MD) technique is widely spread and used both experi­mentally and in clinical practice. The MD technique allows continuous collection of small molecules such as glucose, lactate, pyruvate and glycerol. Samples are often analysed using the CMA 600 analyser, an enzymatic and colorimetric analyser. LÄS MER

  4. 4. Temperature-inducible and calcium-regulated proteins encoded by the virulence plasmid of Yersinia

    Författare :Ingrid Bölin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yersinia; virulence plasmid; gene products; regulation; calcium; temperature; outer membrane proteins;

    Sammanfattning : The pathogenic members of the genus Yersinia, Y. pseudotuberculosis, Y. pestis and Y. enterocolitica are transmitted from animals to man and may give rise to disease with a variety of symptoms. LÄS MER
