  4. 2. Quantum Chemical Modeling of Dye-Sensitized Titanium Dioxide : Ruthenium Polypyridyl and Perylene Dyes, TiO2 Nanoparticles, and Their Interfaces

    Author : Maria J. Lundqvist; Sten Lunell; Petter Persson; Lars Ojamäe; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum chemistry; density functional theory; chromophore; nanocrystal; interface; photoexcitation; triplet state; surface electron transfer; electronic coupling strength; Kvantkemi; Quantum chemistry; Kvantkemi;

    Abstract : Quantum chemical calculations have been used to model dye-sensitized nanostructured titanium dioxide systems that can be used in solar cells for solar energy to electricity conversion. Structural, electronic and spectral properties of isolated dyes and both bare and dye-sensitized TiO2 have been calculated with density functional theory, providing detailed information about both the separate parts and the dye-TiO2 interface.

  6. 4. Trainee teacher identities in the discourses of physics teacher education : Going against the flow of university physics

    Author : Johanna Larsson; John Airey; Anna Danielsson; Eva Lundqvist; Maria Vetleseter Bøe; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; physics; physics teacher education; preservice teacher training; professional identity; identity performances; femininities; discourse analysis; qualitative interviews; educational relevance; gender; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

    Abstract : This thesis investigates what is involved in being recognized as a legitimate physics teacher-to-be in a Swedish physics teacher programme. Drawing on in-depth, qualitative interviews with 17 physics teacher educators and 17 trainee physics teachers, this thesis sees learning to become a physics teacher as a process of performing professional identities.
