  1. 1. Chemically Modified Metal Oxide Nanostructures Electrodes for Sensing and Energy Conversion

    Författare :Sami Elhag; Omer Nour; Magnus Willander; Alberta Bonanni; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Metal oxide nanostructures; mixed metal oxide nano-compound; low temperature wet-chemical growth; chemically modified electrode; doping; surfactant; potentiometric sensor; chemical sensor and photo-electrochemical activity;

    Sammanfattning : The goal of this thesis is the development of scalable, low cost synthesis of metal oxide nanostructures based electrodes and to correlate the chemical modifications with their energy conversion performance. Methods in energy conversion in this thesis have focused on two aspects; a potentiometric chemical sensor was used to determine the analytical concentration of some components of the analyte solution such as dopamine, glucose and glutamate molecules.

  4. 3. Photochemical and Photoelectric Applications of II-VI Semiconductor Nanomaterials

    Författare :Abhilash Sugunan; Mamoun Muhammed; Lars Kloo; KTH; []
    Nyckelord :ZnO; Nanowire arrays; Photocatalysis; Nanofibers; CdTe; Nanotetrapods; Ostwalds ripening; Photoconduction; Nano-gap electrodes;

    Sammanfattning : In this work we investigated fabrication of semiconductor nanomaterials and evaluated their potential for photo-chemical and photovoltaic applications. We investigated two different II-VI semiconductor nanomaterial systems; (i) ZnO oriented nanowire arrays non-epitaxially grown from a substrate; and (ii) colloidal CdTe nanotetrapods synthesized by solution-based thermal decomposition of organo-metallic precursors.
