  1. 6. Combination of nanoparticles from polystyrene and the hormone 17alpha-ethinylestradiol (EE2) in water.

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Emma Nilsson; [2017]
    Nyckelord :water; nanoparticles; hormons; Plastic; Earth and Environmental Sciences;

    Sammanfattning : Plastic materials and synthetic hormones are found in aquatic environments globally. Plastic in water can degrade to nanoparticles (NP) with special characteristics, in the environment nanoparticles and hormones have a proven effect on wildlife. LÄS MER

  3. 7. Plasmonic Effect of Metal Nanoparticles Deposited on Wide-Band Gap Metal Oxide Nanowire Substrate

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Mojtaba Gilzad Kohan; [2017]
    Nyckelord :plasmonic particles; nano wires; wide band gap semiconductors;

    Sammanfattning : The application of nanowires (NWs) in solar cells (SCs) is of great interest due to their new promising aspects established in nanoelectronics. Semiconductors associated with plasmonic metal nanoparticles (NPs) such as Silver (Ag), Gold (Au) and Copper (Cu), show enhanced performance in solid state light absorbing SCs owing to plasmonic characteristic of noble metal NPs.

  4. 8. Merging Electrohydrodynamic Printing and Electrochemistry : Sub-micronscale 3D-printing of Metals

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Marcus Lindén; [2017]
    Nyckelord :additive manufacturing; 3D-printing; microsystem; nanotechnology; nanoscale; EHD; electrochemical; metals;

    Sammanfattning : Additive manufacturing (AM) is currently on the verge of redefining the way we produce and manufacture things. AM encompasses many technologies and subsets, which are all joint by a common denominator; they build three dimensional (3D) objects by adding materials layer-upon-layer. LÄS MER

  5. 9. Simulation of Metal and Metal Oxide Nanoparticle Sedimentation in Solution Using a Computational Model

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Sara Isaksson; [2016]
    Nyckelord :Nanoparticles; sedimentation; simulation; fractal dimension; aqueous environment; Nanopartiklar; sedimentering; simulering; fraktaldimension; vattenmiljö;

    Sammanfattning : Nanoparticles are used in many different applications because of their small size and unique properties. The usage is increasing rapidly, which will increase the nanoparticle exposure to the environment. LÄS MER

  7. 10. Solution-based and flame spray pyrolysis synthesis of cupric oxide nanostructures and their potential application in dye-sensitized solar cells

    M1-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi; Linköpings universitet/Tekniska fakulteten

    Författare :Narin Yousef; [2015]
    Nyckelord :Copper oxide; cupric oxide; nanoparticles; dye sensitized solar cells; Kemisk analysteknik; KA;

    Sammanfattning : The dye sensitized solar cell (DSSC) is a promising low-cost technology alternative to conventional solar cell in certain applications. A DSSC is a photo-electrochemical photovoltaic device, mainly composed of a working electrode, a dye sensitized semiconductor layer, an electrolyte and a counter electrode. LÄS MER
