  1. 1. Luminescent textiles using biobased products : A bioinspired approach

    Författare :Sweta Iyer; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; bioinspired; biobased; bioluminescent; photoluminescent; textile; luminous bacteria; enzymes; immobilization; plasma; riboflavin; flavin mononucleotide; sustainable; digital printing; functionalization; Textil och mode generell ; Textiles and Fashion General ;

    Sammanfattning : Nature has designed a few biobased molecules that are responsible for bioluminescence and photoluminescence in some living species. In this thesis, the potential use of luminescence phenomena existing in nature toward the attainment of luminescent textiles was explored. LÄS MER

  3. 2. Single-­molecule spectroscopy of π-­conjugated polymers

    Författare :Oleg Mirzov; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fluorescence lifetime; low temperature; spectral diffusion; blinking; MEH-PPV; Single-molecule spectroscopy; π-conjugated polymers; 2D polarization; Monte Carlo; energy transfer;

    Sammanfattning : When applied to condensed-matter samples of large organic molecules, optical spectroscopy faces the problem of inhomogeneous broadening caused by the diversity of environments and conformations that sample molecules are subjected to. This severely limits the information that can be extracted from optical spectra. LÄS MER

  4. 3. Towards Harnessing Solar Energy with Iron N-Heterocyclic Carbene Complexes

    Författare :Olga Gordivska; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Negative impact of human activity-related emission of greenhouse gases on Earth's ecosphere has been known for decades, but has recently come into spotlight with unprecedented intensity. This is due to increasingly clear understanding that the global warming could soon spiral out of control. LÄS MER

  5. 4. Photoluminescence-based characterization of bioengineered nanovesicles and erbium emitters

    Författare :Maryam Sanaee; Katia Gallo; Jerker Widengren; Martin Hof; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioengineered nanovesicles; Coincident fluorescent burst analysis; Drug loading; Erbium emitters; Lithium niobate; Photoluminescence.; Bioingenjörskonstruerade nanovesiklar; Analys av sammanfallande fluorescerande blossteknik; Läkemedelslastning; Erbium-emitterare; Lithium niobate; Fotoluminiscens.; Biologisk fysik; Biological Physics; Optics and Photonics; Optik och fotonik;

    Sammanfattning : In recent decades, photoluminescence properties of single molecules and ions have opened new possibilities for studies on smaller size scales, below the light-diffraction limit. In this thesis, the advantages of such single photon emitters were harnessed and studied mainly in the field of biophysics, but also, in investigations within solid state photonics. LÄS MER
