  2. 1. Fabrication and Photoelectrochemical Applications of II-VI Semiconductor Nanomaterials

    Author : Abhilash Sugunan; Muhammet Toprak; Mamoun Muhammed; Gerrit Boschloo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ZnO; nanowire arrays; photocatalysis; CdTe; CdSe; CdS; nanotetrapods; nanotetrahedrons; photoconduction; nano-gap electrodes; Type-II QDs; P3HT nanofibers; microwave synthesis.;

    Abstract : In this work we investigated fabrication of semiconductor nanomaterials and evaluated their potential for photo-chemical and photovoltaic applications. We investigated different II-VI semiconductor nanomaterial systems; (i) ZnO oriented nanowire arrays non-epitaxially grown from a substrate; and (ii) colloidal CdE (E=Te,Se,S) quantum structures synthesized by solution-based thermal decomposition of organo-metallic precursors.

  5. 3. Aqueous graphene dispersions for paper packaging

    Author : Wei Zhao; Anwar Ahniyaz; Abhilash Sugunan; Thomas Gillgren; Johan A. Larsson; Zhi-Bin Zhang; Shi-Li Zhang; Valeria Nicolosi; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Graphene; Aqueous graphene dispersions; Noncovalent interactions; Composites; Barriers; Inkjet printing; Kemi med inriktning mot kemisk fysik; Chemistry with specialization in Chemical Physics;

    Abstract : Graphene is widely touted as the thinnest and the most versatile material available. As an atomically thin layer of carbon atoms arranged in a hexagonal configuration, graphene has a combination of technologically important properties, such as thermal and electrical conductivity, mechanical strength, and impermeability to gases.
