  1. 11. Ash chemistry and fuel design focusing on combustion of phosphorus-rich biomass

    Author : Nils Skoglund; Dan Boström; Rainer Backman; Franz Winter; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phosphorus; biomass; combustion; ash chemistry; fuel design; ash transformation; phosphorus-rich; ash-forming elements; fuel fingerprint; ash transformation reactions; Lewis base; Lewis acid; oorganisk kemi; Inorganic Chemistry;

    Abstract : Biomass is increasingly used as a feedstock in global energy production. This may present operational challenges in energy conversion processes which are related to the inorganic content of these biomasses. As a larger variety of biomass is used the need for a basic understanding of ash transformation reactions becomes increasingly important. READ MORE

  2. 12. Phosphine ligands with triamine functionality - preparation and application in catalysis

    Author : Magnus Karlsson; Enheten för fysikalisk och teoretisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; water soluble; palladium; amphiphilic; rhodium; Oorganisk kemi;

    Abstract : Incorporation of the triamine, bis(2-diethylaminoethyl) amine as a side chain substituent on triphenylphosphine, (2S,4S)-4-diphenylphosphino-2-diphenylphosphino-methylpyrrolidine (PPM) or (R,R)-3,4-bis(diphenylphosphin)pyrrolidine (Pyrphos) gives the three new amphiphilic ligands N3P, N3PPM and N3-Pyrphos respectively. Because of the triamine functionality the distribution of the ligands and their complexes between water and an organic solvent is controlled by the pH of the aqueous phase. READ MORE

  3. 13. Model Systems for Metal - DNA Interactions. With a Focus on Anticancer Active Platinum(II) Complexes

    Author : Anna Ericson; Kemiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; kinetics; DNA; poly d T ; guanine; 6-thioinosine-5 -monophosphate; 6-thio-2 -deoxyinosine; 4-thiouridine-5 -monophosphate; 4-thio-2 -deoxyuridine; palladium II ; Gold III ; platinum II ; mechanism; salt effect; activation parameters; Inorganic chemistry; Oorganisk kemi;

    Abstract : Reactions of trans-dicyanodichloroaurate(III) trans-dibromodicyanoaurate(III), trans-diamminedichlorogold(III), cis-diammine(aqua)chloroplatinum(II), cis-ammineaqua-(cyclohexylamine)chloroplatinum(II), chloro(terpyridine)platinum(II) and chloro-(diethylenetriaminepalldium(II) with dimethyl sulfide, thionucleosides, thionucleotides and thione- and guanine-containing 17-mer oligonucleotides have been investigated by use of conventional and high-pressure stopped-flow spectrophotometry and HPLC technique as a function of ionic strength, pH, temperature and pressure in aqueous solutions. The mechanism and rate of oxidation of dimethyl sulfide by gold(III) complexes depends on the concentration of free halide. READ MORE

  4. 14. The Role of Tetrahedral Building Blocks in Low-Dimensional Oxohalide Materials

    Author : Iwan Zimmermann; Mats Johnsson; Lars Kloo; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lone-pair elements; crystal structure; low-dimensional compounds; oxohalides; Inorganic Chemistry; oorganisk kemi;

    Abstract : The structural architecture found in low-dimensional materials can lead to a number of interesting physical properties including anisotropic conductivity, magnetic frustration and non-linear optical properties. There is no standard synthesis concept described thus far to apply when searching for new low-dimensional compounds, and therefore control on the design of the new materials is of great importance.
