  3. 22. 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. 23. Ozone chemistry in aqueous solution : ozone decomposition and stabilisation

    Författare :Margareta Eriksson; Lars Kloo; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi;

    Sammanfattning : Ozone is used in many applications in the industry as an oxidising agent for example for bleaching and sterilisation. The decomposition of ozone in aqueous solutions is complex, and is affected by many properties such as, pH, temperature and substances present in the water. LÄS MER

  5. 24. 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.

  7. 25. On the nature of main-group polycations : an odyssey

    Författare :Martin Lindsjö; Lars Kloo; Michael Ruck; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Inorganic chemistry; Kemi; Chemistry; Kemi;

    Sammanfattning : Compounds containing main-group clusters, with focus on bismuth polycations, have been synthesized and characterized using X-ray diffraction and spectroscopic methods. Six new compounds have been isolated from synthesis in GaX3-arene media; Bi8[GaCl4]2, Bi8 [GaBr4]2, Sb8[GaCl4]2, Sb8[GaBr4]2, Te4[Ga2Cl7]2 and Te4[Ga2Br7]2. LÄS MER
