  1. 1. Functional Metal Oxide Materials Deposited by Inkjet Printing Technique

    Författare :Yan Wu; Lyubov Belova; Gillian Gehring; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inkjet printing; photoconductivity; ZnO; Al-ZnO; composite; electron transfer; CdS; field effect transistor; photosensitive; RT do-ferromagnetism; Mn-doped ZnO; MgO; Materials science; Teknisk materialvetenskap;

    Sammanfattning : This thesis presents a comprehensive study of the intrinsic room temperature ferromagnetism in 85 to 100nm thin films produced by in situ deposition of industrially important pristine MgO and ZnO by inkjet printing. It is suggested that the observed long range magnetic order, the so-called do magnetism in these oxides arises from cation vacancies. LÄS MER

  4. 3. Molecular Interaction of Thin Film Photosensitive Organic Dyes on TiO2 Surfaces

    Författare :Shun Yu; Mats Göthelid; Chassé Thomas; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photoelectron spectroscopy; X-ray absorption spectroscopy; organic semiconductor; oxides; adsorption; dye sensitization; electronic structure; charge transfer;

    Sammanfattning : The photosensitive molecule adsorption on titanium dioxide (TiO2) forms the so-called “dye sensitized TiO2” system, a typical organic/oxide heterojunction, which is of great interest in catalysis and energy applications, e.g. dye-sensitized solar cell (DSSC). Traditionally, the transition metal complex dyes are the focus of the study. LÄS MER

  5. 4. Selective wavelength pupillometry to evaluate outer and inner retinal photoreception

    Författare :Aki Kawasaki; Fatima Pedrosa Domellöf; Bertil Lindblom; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pupil; pupil light reflex; melanopsin; photoreceptor; intrinsically photosensitive retinal ganglion cell; oftalmiatrik; Ophtalmology;

    Sammanfattning : PurposeIntrinsically photosensitive retinal ganglion cells (ipRGCs) express a unique photopigment called melanopsin. Capable of direct phototransduction, the ipRGCs are also influenced by rods and cones via synaptic inputs. LÄS MER

  7. 5. Light induced destruction of indole-3-acetic and some physiological effects on one of its metabolites, 3-methyleneoxindole

    Författare :Punam Bhatnagar; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Studies conducted on Lemma gibba in sterile nutrition medium with labelled indole-3-acetic acid (IAA-1- 14C), confirmed that IAA is highly photosensitive in aqueous solutions. About 80 % of the IAA was decarboxylated within 24 h of exposure to fluorescent light. LÄS MER
