  1. 6. Luminescence Properties of ZnO Nanostructures and Their Implementation as White Light Emitting Diodes (LEDs)

    Författare :Naveed ul Hassan Alvi; Magnus Willander; Omer Nour; Vladimir V. Mitin; Linköpings universitet; []
    Nyckelord :Nanotechnology; Zinc oxide; nanostructures; luminescence; LEDs; color rendering; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : In this thesis, luminescence properties of ZnO nanostructures (nanorods, nanotubes, nanowalls and nanoflowers) are investigated by different approaches for possible future application of these nanostructures as white light emitting diodes. ZnO nanostructures were grown by different growth techniques on different p-type substrates. LÄS MER

  3. 7. Inhibition of Calcium and Zinc Absorption by Phytate in Man Methodological Studies and Hydrothermal Processing of Cereals to Improve Absorption

    Författare :Kerstin Fredlund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; barley; wheat; rye; 65Zn; oats; zinc absorption; whole grains; InsP6; hydrothermal processing; calcium absorption; rice; radionuclide technique; 47Ca; extrinsic labelling; phytate; hydrothermal treatment; myo-inositol; calcium retention; whole-body counting;

    Sammanfattning : A mathematical model based on measurements in a whole-body counter described the retention of calcium in the human body. It was shown that the relative retention of intravenous and orally administered 47Ca in all subjects (n = 10 - 11) were well described by fitting a simple function of time with two free parameters to a few whole-body measurements after day 6, when the unabsorbed calcium had been excreted.

  5. 9. Heterojunctions between zinc oxide nanostructures and organic semiconductor

    Författare :Amal Hansson (f.d. Wadeasa); Xavier Crispin; Dominique Vuillaume; Linköpings universitet; []
    Nyckelord :ZnO nanostructures; Organic semiconductors; LEDs; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Lighting is a big business, lighting consumes considerable amount of the electricity. These facts motivate for the search of new illumination technologies that are efficient. Semiconductor light emitting diodes (LEDs) have huge potential to replace the traditional primary incandescent lighting sources. LÄS MER

  7. 10. Chemical fabrication of ZnO nanostructures and their emission properties: Cholesterol biosensing applications utilizing ZnO and Graphene

    Författare :Muhammad Israr Qadir; Magnus Willander; Omer Nour; Jinhui Song; Linköpings universitet; []
    Nyckelord :Zinc oxide; aqueous chemical synthesis; nanostructures; light emitting diode; electrochemical biosensor.; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Zinc oxide (ZnO) is an inorganic compound, owing to wide band gap and large binding energy, and holds promising potential in the fields of semiconducting as well as piezoelectric applications with excellent stability and reliability. In addition, ZnO has a plenteous number of nanoscale structures containing unique physical, chemical, electrical, sensing and optical properties. LÄS MER
