  1. 1. Mechanisms of Anion Reactions from the lab to ionospheres

    Author : Fredrik Lindén; Wolf D. Geppert; Henrik Cederquist; Henning Zettergren; Einar Uggerud; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ab initio; anion; complex molecules; cross section; electron transfer; heavy ions; ionosphere; nitriles; quantum chemistry; spectroscopy; kemisk fysik; Chemical Physics;

    Abstract : A multitude of heavy neutral and ionic molecules have been discovered by the Cassini Plasma Spectrometer in the ionosphere of Saturn's largest moon Titan. However, only three cyano anions were explicitly identified there, namely CN-, C3N- and C5N-. READ MORE

  2. 2. Diffusion of Radionuclides in Bentonite Clay : Laboratory and in sity Studies

    Author : Mats Jansson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bentonite; montmorillonite; cation; anion; diffusion; sorption; cobalt; caesium; strontium; iodide; pertechnetate; surface diffusion; in situ; Chemistry; Kemi;

    Abstract : This thesis deals with the diffusion of ions in compactedbentonite clay. Laboratory experiments were performed toexamine in detail different processes that affect thediffusion. To demonstrate that the results obtained from thelaboratory investigations are valid under in situ conditions,two different kinds of in situ experiments were performed. READ MORE

  3. 3. Non-covalent Modification of Graphene and MoS2 Synthesis and Characterization of Charged Molecules and Two-Dimensional Materials

    Author : Steffen Brülls; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sensors.; molybdenum disulfide; intermolecular interactions; charged π-conjugated systems; doping; non-covalent interactions; functionalization; cation; Graphene; anion;

    Abstract : Graphene is a material of superlatives. It has unique properties, which are explored in various areas of interdisciplinary research. Graphene can improve the properties of other materials or even give them new functions and is therefore a suitable candidate for different sensor applications. READ MORE

  4. 4. Modulating the anion ordering in apatites

    Author : Peter Alberius-Henning; Juan Manuel Pérez-Mato; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; oorganisk kemi; Inorganic Chemistry;

    Abstract : Hydroxyapatite constitutes the main inorganic part of the skeleton, and since the beginning of the seventies, synthetic apatite has been used in implants. The physical properties of this crystalline material are directly dependent on its atomic arrangement. If a better understanding of apatite chemistry is sought, important for e.g. READ MORE

  5. 5. Poly(phenylene oxide)s functionalized with cationic side chains: design, synthesis and properties as anion exchange membranes

    Author : Hai-Son Dang; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; anion exchange membranes; Anion exchange membrane fuel cells; poly phenylene oxide s; hydroxide conductivity; alkaline stability; lithiation; Menshutkin reaction;

    Abstract : Anion exchange membrane fuel cells (AEMFCs) are considered as one of the most important next-generation energy conversion technologies. AEMFCs convert chemical energy into useful electrical energy and have great potential forachieving high conversion efficiencies. READ MORE
