  1. 16. Interfaces in Organic Solar Cells

    Författare :Xian'e Li; Mats Fahlman; Xianjie Liu; Artem Bakulin; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Organic semiconductors (OSs), the promising candidates for the next generation electronic devices, have shown their advantages of light weight, flexibility, semi-transparency, tunable optical gaps, and energy levels, in the development history of over 70 years. OSs have been widely used in versatile applications such as organic light-emitting diodes, organic field-effect transistors, organic photodetectors, and organic solar cells (OSCs) which are mainly studied in this thesis.

  3. 17. Effective Field Theory for QCD-like Theories and Constraints on the Two Higgs Doublet Model

    Författare :Jie Lu; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; QCD-like; effective field theory; symmetry breaking; renormalization group; two Higgs doublet model;

    Sammanfattning : This thesis includes two topics.The first three papers is the major part of this thesis, which is about higher order calculations in the effective field theories of three QCD-like theories. These three QCD-like theories are distinguished by having quarks in a complex, real or pseudo-real representation of gauge group. LÄS MER

  4. 18. Ultra-fast dynamics in atoms and molecules during photoionization: from attoseconds to femtoseconds

    Författare :Erik Månsson; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photoelectron spectroscopy; momentum imaging; coincident detection; correlation; direct double ionization; Born–Oppenheimer approximation; high harmonics; synchrotron radiation; Fysicumarkivet A:2014:Månsson;

    Sammanfattning : Treating the correlated behaviour of multiple particles is challenging for both theory and experiment. This thesis reports on a variety of experimental investigations aiming to advance the understanding of fundamental processes in atoms and molecules: double ionization, isomerization and dissociation.

  5. 19. Där eleverna är : Ett arenaperspektiv på skolan som en stödjande miljö för hälsa

    Författare :Maria Warne; Katja Gillander Gådin; Kristen Snyder; Monica Eriksson; Mittuniversitetet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adolescents; empowerment; health promotion; participation; positive health; salutogenic; settingsapproach; pupils; support; supportiv environment; students; teenagers; recuperation; youth; arenabaserat; barn; delaktighet; elever; empowerment; hälsofrämjande; positiv hälsa; salutogenes; stödjande miljö; tonåringar; ungdomar; återhämtning;

    Sammanfattning : Hälsa skapas inte i ett vakuum utan i relation mellan individer och omgivning. Skolan är därför en viktig arena för barn och ungdomar eftersom de tillbringar större delen av sin vakna tid där. LÄS MER

  7. 20. Plant Membrane Proteomics - using isolated membranes and proteins to compare and quantify subproteomes

    Författare :Katja Bernfur; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mass spectrometry; quantification; proteomics; metabolic labeling; plasma membrane;

    Sammanfattning : Membrane proteins are particularly important to characterize, since they are involved in cellular processes of utmost importance in control and regulation of cells, such as transport across membranes, signal transduction and photosynthesis. The word "proteome" means all proteins expressed by a e.g. LÄS MER
