  1. 16. Lighting and Sensing Applications of Nanostructured ZnO, CuO and Their Composites

    Författare :Ahmed ELtahir Elsharif Zainelabdin; Magnus Willander; Omer Nour; Leonard J. Brillson; Linköpings universitet; []
    Nyckelord :ZnO; CuO; Nanostructures; Composites; ZnO polymer LEDs; humidity sensor; p-n heterojunction;

    Sammanfattning : Low dimensional nanostructures of zinc oxide (ZnO), cupric oxide (CuO), and their composite nanostructures possess remarkable physical and chemical properties. Fundamental understanding and manipulation of these unique properties are crucial for all potential applications. LÄS MER

  3. 17. Technological Aspects of Preparing Porridges Made from Local Crops in Mozambique

    Författare :Irene Carvalho; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Child malnutrition; consistency; complementary porridge; developing countries; energy density; carotenoids;

    Sammanfattning : Child malnutrition is one of the major health problems in many developing countries and involves many sectors such as health, agriculture and research. Malnutrition in infants usually develops during the introduction of complementary foods, due to a deficit of nutrients, low energy density and the poor bioavailability of vitamins and minerals leading, in turn, to an increase in the risk of disease and infant mortality.

  4. 18. 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.

  5. 19. Synthesis of ZnO, CuO and their Composite Nanostructures for Optoelectronics, Sensing and Catalytic Applications

    Författare :Saima Zaman; Magnus Willander; Omer Nour; Andrey Bakin; Linköpings universitet; []
    Nyckelord :ZnO; CuO; Nanostructures; Low temperature growth; Light emitting diodes; pH sensors;

    Sammanfattning : Research on nanomaterials has become increasingly popular because of their unique physical, chemical, optical and catalytic properties compared to their bulk counterparts. Therefore, many efforts have been made to synthesize multidimensional nanostructures for new and efficient nanodevices. LÄS MER

  7. 20. Suppressor of zeste 12, a Polycomb group gene in Drosophila melanogaster; one piece in the epigenetic puzzle

    Författare :Anna Birve; Anssi Saura; Allen Shearn; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Drosophila melanogaster; epigenetic; homeotic genes; Polycomb group; PRE; heterochromatin; Suppressor of zeste 12; chromatin silencing; Genetik; Clinical genetics; Klinisk genetik; Genetics; genetik;

    Sammanfattning : In multicellular organisms all cells in one individual have an identical genotype, and yet their bodies consist of many and very different tissues and thus many different cell types. Somehow there must be a difference in how genes are interpreted. So, there must be signals that tell the genes when and where to be active and inactive, respectively. LÄS MER
