  2. 1. Being political in the media – Political identities in journalistic and Twitter discourse

    Author : Gustav Persson; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; political identities; critical discourse analysis; subjectivity; activism; political engagement; political identities;

    Abstract : This thesis is about the role of media discourse in shaping the political identities of those who want to be heard in public. The ways in which people are able to speak, know, and feel in political situations have important implications for how we conceive of the possibilities to be engaged in contemporary democracy.

  4. 2. Correlating Nanostructure and Electronic Properties of Organic Semiconductors by Electron Microscopy

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

    Abstract : Organic semiconductors enable fabrication and efficient processing of electronic devices with light weight, mechanical flexibility and tuneable properties. Despite significant progress in the last decades, efficiencies and long-term stabilities of these systems still need to be improved. READ MORE

  5. 3. Temporal Modulation in Fluorescence Spectroscopy and Imaging for Biological Applications

    Author : Gustav Persson; Jerker Widengren; Jörg Enderlein; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluorescence; spectroscopy; microscopy; modulated excitation; intensity modulation; fluorescence correlation spectroscopy; transient states; molecular kinetics; Physics; Fysik;

    Abstract : This thesis explores the benefits of intensity modulation for the purpose of extending the range of applications of fluorescence spectroscopy and imaging in cellular and molecular biology and medicine. Long-lived transient states of fluorescent molecules can, because of their long lifetimes, be used to detect subtle changes in the microenvironment of the molecule. READ MORE

  6. 4. Time-Varying Excitation in Fluorescence Spectroscopy for Biological Applications

    Author : Gustav Persson; Jerker Widengren; Måns Ehrenberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluorescence; spectroscopy; molecular kinetics; Physics; Fysik;

    Abstract : The focus of this thesis is to explore and use the benefits of time-varying excitation in fluorescence spectroscopy for studies of biomolecular dynamics. Two new techniques taking advantage of modulated excitation are presented. READ MORE

  7. 5. Visualising Functional Nanostructures of Organic Semiconductors using Electron Microscopy

    Author : Gustav Persson; Chalmers tekniska högskola; []
