  1. 16. Sport in youth detention : A “pedagogical” practice?

    Författare :Daniel Roe; Håkan Larsson; Martin Hugo; Rosie Meek; Gymnastik- och idrottshögskolan; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sport pedagogy; youth justice; youth detention; corrections; pedagogical tact; critical pedagogy; marginalized masculinity; ethnography; football; weightlifting; Sweden; Samhällsvetenskap Humaniora; Social Sciences Humanities;

    Sammanfattning : Sport can be an important part of life inside youth detention, often believed to contribute to the rehabilitation of youth. However, there has been little ethnographic research examining this phenomenon. LÄS MER

  3. 17. A Theoretical Study: The Connection between Stability of Single-Walled Carbon Nanotubes and Observed Products

    Författare :Daniel Hedman; Andreas Larsson; Sven Öberg; Krisztián Kordás; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Single-walled carbon nanotubes; density functional theory; catalytic chemical vapor deposition; chirality-specific growth; stability; length; diameter; edge; chirality; Applied Physics; Tillämpad fysik;

    Sammanfattning : Over the past 20 years’ researchers have tried to utilize the remarkable properties of single-walled carbon nanotubes (SWCNTs) to create new high-tech materials and devices, such as strong light-weight composites, efficient electrical wires and super-fast transistors. But the mass production of these materials and devices are still hampered by the poor uniformity of the produced SWCNTs. LÄS MER

  4. 18. Single-Walled Carbon Nanotubes : A theoretical study of stability, growth and properties

    Författare :Daniel Hedman; Andreas Larsson; Sven Öberg; Esko I. Kauppinen; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Applied Physics; Tillämpad fysik;

    Sammanfattning : Since their discovery over 25 years ago, scientists have explored the remarkable properties of single-walled carbon nanotubes (SWCNTs) for use in high-tech materials and devices, such as strong light-weight composites, efficient electrical wires, supercapacitors and high-speed transistors. However, the mass production of such materials and devices is still limited by the capability of producing uniform high-quality SWCNTs. LÄS MER

  5. 19. Window Layer Structures for Chalcopyrite Thin-Film Solar Cells

    Författare :Fredrik Larsson; Tobias Törndahl; Jan Keller; Marika Edoff; Daniel Lincot; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CIGS; atomic layer deposition; ALD; thin-film technology; window layer structures; buffer layers; front contacts; metal oxides; ternary compounds; CIGS; tunnfilmssolceller; ALD; tunnfilmsteknik; fönsterlager; buffertlager; framkontakter; metalloxider; ternära föreningar; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Sammanfattning : This thesis aims to contribute to the development of improved window layer structures for chalcopyrite thin-film solar cells, with an emphasis on the buffer layer, to assist future reductions of the levelized cost of energy. This is realized by exploring the potential of existing materials and deposition processes, as well as developing new buffer layer processes based on atomic layer deposition (ALD). LÄS MER

  7. 20. Surface Stabilization and Electrochemical Properties from a Theoretical Perspective

    Författare :Daniel Petrini; Karin Larsson; Jan-Otto Carlsson; Martin Stutzmann; Uppsala universitet; []
    Nyckelord :Inorganic chemistry; DFT; Diamond; High surface conductivity; Surface reactivity; c-BN; Oorganisk kemi;

    Sammanfattning : Diamond and cubic boron nitride surfaces have extreme properties that can be exploited in novel tribological, electrochemical and electronic applications. Normally insulating diamond surfaces can exhibit high surface conductivities due to hydrogen termination and the nature of the surrounding atmosphere. LÄS MER
