  1. 1. Magnetism and Structure of Thin 3d Transition Metal Films : XMCD and EXAFS using Polarized Soft X-Rays

    Författare :Anders Hahlin; Dimitri Arvanitis; Olof Karis; Claus Schneider; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; thin film; xmcd; exafs; anisotropy; coherence; circular polarization; magnetism; Fe; Co; Ag; Fysik; Physics; Fysik; Fysik; Physics;

    Sammanfattning : In this Thesis the magnetic and structural properties of thin epitaxial Fe, Co, and Ni films are discussed. Some of the in-situ prepared samples were used to characterize the degree of circular polarization of the newly installed beamline D1011 at MAX-lab. LÄS MER

  3. 2. La motivation et le concept de soi : Regards croisés de l'élève et de l'enseignant de français langue étrangère en Suède

    Författare :Céline Rocher Hahlin; Franska; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; Motivation; French; Language learning; Language teaching; Self Concept; Teacher psychology; Motivation; Språkinlärning; Franska; Språkundervisning; Självuppfattning; Motivation; Språkinlärning; Franska; Språkundervisning; Självuppfattning; French; Language learning; Language teaching; Self Concept; Teacher psychology;

    Sammanfattning : This thesis contains two studies focusing on motivation in learning and teaching French as a foreign language in Sweden. In the first study, the effect of three specifically designed pedagogical activities on learners’ Ideal French Self (IFrS) and Intended Effort (IE) was examined in a group of 15-year-old Swedish pupils.

  4. 3. Electronic and Molecular Surface Structures of Dye-Sensitized TiO2 Interfaces

    Författare :Maria Hahlin; Håkan Rensmo; Hans Siegbahn; Anders Sandell; Mats Göthelid; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photoelectron spectroscopy; Electron spectroscopy; Solar Cells; Dye; TiO2; Surface; Interface; Electronic structure; Molecular surface structure; coadsorbent; Physics; Fysik; Fysik; Physics;

    Sammanfattning : The dye-sensitized solar cell is a promising solar cell technology. In these systems the key process for light to electricity conversion is molecular in nature and is initiated in dye molecules adsorbed at a semiconducting surface. LÄS MER

  5. 4. Motivation pour apprendre une langue étrangère – une question de visualisation? : Les effets de trois activités en cours de français sur la motivation d’élèves suédois

    Författare :Céline Rocher Hahlin; Franska; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; French; Motivation; Dörnyei; Ideal Language Self; Ideal L3 Self; Intended effort; language acquisition; L3; language learning; foreign language; classroom activities;

    Sammanfattning : Despite the vast research on motivation and foreign language acquisition during the last decades, little is known about the motivational effects of concrete pedagogical activities in the classroom. The work of, among others, Z. Dörnyei shows that imagined reality can have positive effects on language learning outcomes. LÄS MER

  7. 5. Ionization Influence on the Dynamics of Simple Organic Molecules

    Författare :Tomoko Akiyama; Carl Caleman; Oscar Grånäs; Olle Björneholm; Maria Hahlin; Uppsala universitet; []
    Nyckelord :Small organic molecule; Density functional theory; bond integrity; Symmetric structure;

    Sammanfattning : This licentiate thesis is devoted to the investigation of how bonding in simple organic molecules are affected by X-ray beam irradiation. The investigation targets molecules with three carbons as their main-chain structure. The stability of the bonds under ionization are simulated using the SIESTA package. LÄS MER
