  1. 1. Ionic Liquid Electrolytes for Photoelectrochemical Solar Cells

    Författare :Heléne Gamstedt; Lars A. Kloo; Michael Grätzel; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ionic liquid electrolytes; Photoelectrochemical solar cells; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : Potential electrolytes for dye-sensitized photoelectrochemical solar cells have been synthesized and their applicability has been investigated. Different experimental techniques were used in order to characterize the synthesized electrolytes, such as elemental analysis, electrospray ionisation/mass spectrometry, cyclic voltammetry, dynamic viscosity measurements, as well as impedance, Raman and NMR spectroscopy.

  3. 2. Red Glass Coloration : a Colorimetric and Structural Study

    Författare :Torun Bring; Lars Kloo; Alicia Duran; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi;

    Sammanfattning : Syftet med detta arbete har varit att försöka hitta alternativ till det kadmiumbase¬rade röda pigment som används idag. Detta har gjorts genom att delvis under¬söka kombinationer av grundämnen som i litteraturen finns omnämnda som röda glaspigment, delvis genom att försöka förbättra och underlätta produktionen av redan kända, men problematiska pigment.

  4. 3. A new synthetic strategy for low-dimensional compounds : Lone pair cations and alkaline earth spacers

    Författare :Rie Takagi Fredrickson; Mats Johnsson; Sven Lidin; Lars Kloo; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alkaline earth; Lone pair elements; Low-dimensional compounds; Inorganic chemistry; Oorganisk kemi; oorganisk kemi; Inorganic Chemistry;

    Sammanfattning : Complex transition metals oxyhalides containing a lone pair element, such as tellurium (IV), form an attractive research field because there is a high probability of finding new low-dimensionally arranged compounds and, particularly, a low-dimensionally arranged transition metals substructures, leading to interesting physical properties. Tellurium (IV) can drive the formation of many unusual structures because of its stereochemically active lone pair electrons, E. LÄS MER

  5. 4. A Theoretical Investigation of the Octapeptide Region in the Human Prion Protein

    Författare :Eva-Stina Riihimäki; Lars Kloo; José Manuel Martínez; Francisco Javier Luque Garriga; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; prion protein; copper; octapeptide; structure; force field parameters; coordination; non-periodic boundary conditions; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : Den kopparbindande egenskapen hos prionproteiner är sannolikt kopplad till proteinets funtion. Det mänskliga prionproteinet innehåller ett kopparbindande oktapeptidområde, där PHGGGWGQ-sekvensen upprepas fyra gånger i följd. LÄS MER

  7. 5. Innate Confinement Effects in PCL Oligomers as a  Route to Confined Space Crystallisation

    Författare :Nima Sanandaji; Ulf W. Gedde; Mikael Hedenqvist; Lars Kloo; Ulrica Edlund; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Crystallisation; Polycaprolactone; PCL; Confined state crystallisation; Metastable Phases; Chemistry; Kemi;

    Sammanfattning : In this work, an in-depth analysis of crystalline characteristics has been performed for a unique set of strictly monodisperse poly-ε-caprolactone (PCL) oligomers. The molecules have different sets of end groups with various degrees of bulkiness and hydrogen bonding potential, affecting their aptitude to pack in ordered crystal structures. LÄS MER
