  1. 1. Discovering Hidden Traps : in Nickel Oxide Nanoparticles for Dye-Sensitised Photocathodes

    Författare :Luca D'Amario; Leif Hammarström; James Durrant; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The finite nature of fossil fuels and their effect on the global climate, raised the need to find an alternative source of energy. This source should be environment compatible, cheap and abundant. The light coming from the Sun is a promising alternative. LÄS MER

  3. 2. Traps and transformations : Exploring the potential of water system innovations in dryland sub-Saharan Africa

    Författare :Elin Enfors; Line Gordon; Christian Valentin; Stockholms universitet; []
    Nyckelord :smallholder farming; water system innovations; agricultural droughts; multi-functional landscapes; development trajectories; uncertainty; NATURAL SCIENCES; NATURVETENSKAP; naturresurshushållning; Natural Resources Management;

    Sammanfattning : In semi-arid and dry sub-humid sub-Saharan Africa (SSA), high poverty levels and a heavy reliance on small-scale rainfed agriculture make rural livelihoods difficult. Upgrading current farming systems, in a way that safeguards productivity beyond field-scale, is urgent. LÄS MER

  4. 3. Imaging and Spectroscopic Mapping of Blood Cell Activity : Nanoparticles and Neutrophil Extracellular Traps

    Författare :Kalle Bunnfors; Kajsa Uvdal; Caroline Brommesson; Christelle Prinz; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Neutrophils; Neutrophil extracellular traps; fluorescence; XPS; TEM;

    Sammanfattning : Imaging and visualization of cell activity when exposed to nanomaterial are of main importance, when investigating biological response to a wide range of biomaterials from medical implants to smart nanoprobes. The ability to provide molecular and chemical information with spatial resolution in the region of sub-µm leads to increased insight and understanding of these biological challenges. LÄS MER

  5. 4. Essays on Taxation, Externalities, and Poverty Traps

    Författare :Fei Ao; Daniel Spiro; Chuan-Zhong Li; Thomas Aronsson; Jukka Pirttilä; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Optimal Taxation; Externalities; Poverty traps; Aid; Economics; Nationalekonomi;

    Sammanfattning : This thesis consists of three self-contained essays.Essay I characterizes the optimal mix of linear commodity taxation and non-linear income taxation in a dynamic economy where consumption gives rise to positional and environmental externalities. LÄS MER

  7. 5. Electrical Characterization of III-V Nanostructure

    Författare :Aein Shiri Babadi; Institutionen för elektro- och informationsteknik; []
    Nyckelord :High-κ; Metal-Oxide-Semicondcutor capacitors; MOSCAPs; III-V semiconductors; InAs; GaSb; interface traps; border traps; C-V; Simulations; Nanowire; MOSFET; Fabrication;

    Sammanfattning : This thesis investigates the electronic properties of a number of novel III-V materials and material combinations for transistor applications. In particular, high-κ/InAs metal-oxide-semiconductor (MOS) structures and transport properties of GaSb nanowires have been studied. LÄS MER
