  2. 21. Surface chemistry of Al and Si (hydr)oxides, with emphasis on nano-sized gibbsite (α-Al(OH)3)

    Author : Jörgen Rosenqvist; Umeå universitet; []
    Keywords : Gibbsite; silica; kaolinite; surface complexation; protonation; adsorption; carboxylates; modeling; AFM; IR; XPS;

    Abstract : This thesis contains an introduction to the surface chemistry of minerals in aqueous environment, and a summary of five manuscripts concerning adsorption reactions at the surfaces of nano-sized gibbsite (α-Al(OH)3), amorphous silica and kaolinite. Nano-sized gibbsite was synthesized and thoroughly characterized using X-ray diffraction, high-resolution transmission electron microscopy, atomic force microscopy and Fourier transform infrared spectroscopy.

  4. 22. Platinum(II) and Palladium (II) Complexes with Group 14 and 15 Donor Ligands. Synthesis, Structure and Substitution Mechanisms

    Author : Ola Wendt; Kemiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mechanism; kinetics; substitution; platinum; palladium; aryl; silyl; nitrile; triphenylstibine; NMR; IR; Raman; X-ray crystallography; stopped-flow; synthesis; Inorganic chemistry; Oorganisk kemi;

    Abstract : The present thesis deals with Pd(II) and Pt(II) complexes with group 14 and 15 donor ligands. Such complexes have been prepared and investigated mainly with regard to their ground state structures and the mechanism according to which they undergo substitution. READ MORE

  5. 23. Three or Four Ir/relevant Stories : Art and Hyper-Politics

    Author : Behzad Khosravi Noori; Magnus Bärtås; Helene Frichot; Boris Buden; KTH; []
    Keywords : HUMANIORA; HUMANITIES; 1. Microhistory; 2. Itinerancy; 3. Global South; 4. Monument; 5. Contemporary history; 6. Public art; 7. Non-Aligned Movement; 8. Iran. 9. Zagreb Film; 10. Animation.; Art; Technology and Design; Konst; teknik och design;

    Abstract : This book documents and reflects on three artistic projects and their processes. As a “marginalia” to the projects I also presents arguments, stories and ir/ relevant discourses. What I call marginalia extends to aspects of a historical backdrop of these three projects and the stories behind them. READ MORE

  6. 24. Micro-galvanic effects and corrosion inhibition of copper-zinc alloys

    Author : Mattias Forslund; Jinshan Pan; Christofer Leygraf; Per Claesson; Jin Ying; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Copper; zinc; brass; octadecanethiol; IR Spectroscopy; AFM; atmospheric corrosion; aqueous corrosion; corrosion inhibition; Koppar; zink; mässing; oktadekantiol; IR-reflektions absorptionsspektroskopi; AFM; atmosfärisk korrosion; vattenaktig korrosion; korrosionsinhibering.; Chemical Engineering; Kemiteknik; Kemi; Chemistry;

    Abstract :    With the advancement and accessibility of local probing techniques that can operate at the submicron scale it has become possible to analyse the local corrosion properties of industrially important metallic materials and relate these properties to microstructure characteristics of the same materials. In this doctoral study the focus has been on copper-zinc samples, both as industrial brass alloys and as micro-patterned copper-zinc samples. READ MORE
