  2. 6. Carbon Balance Implications of Forest Biomass Production Potential

    Author : Bishnu Chandra Poudel; Inga Carlman; Johan Bergh; Thomas Lundmark; Roger Sathre; Mittuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; forest management; silviculture; clear-cut forestry; continuous-cover forestry; substitution; total carbon; climate benefit; climate change; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Forests in boreal and temperate forest-ecosystems have importance for carbonbalance since they sequester large amount of atmospheric carbon by uptake ofcarbon-dioxide during photosynthesis, and transfer and store carbon in the forestecosystem. Forest material can be used for bio-fuel purposes and substitute fossilfuels, and supply wood products, which can replace carbon-and-energy-intensivematerials. READ MORE

  4. 7. Structure-Reactivity Correlations for Reactions of Palladium(II) and Platinum(IV) Complexes

    Author : Tiesheng Shi; Kemiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thiol; l-methionine; maleic acid; carboxylic acid; thioether; platinum IV ; palladium II ; linear free energy relationship; volumes of activation; structure-reactivity correlation; reduction; substitution; equilibria; kinetics; mechanism; glutathione; Animal physiology; Djurfysiologi;

    Abstract : The kinetics and mechanism for substitution reactions on tetraaquapalladium(II) by an extended series of thioethers, a great number of carboxylic acids, and olefins have been studied by use of UV-VIS, stopped-flow, and high-pressure stopped-flow spectrophotometry and NMR spectroscopy. Second-order rate constants k and activation parameters (activation enthalpies, entropies, and volumes) for formation of monodentate 1:1 complexes have been determined. READ MORE

  5. 8. Thermoelectric Ba8Ga16Ge30 clathrates for waste heat recovery

    Author : Daniel Cederkrantz; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thermal stability; substitution; thermal conductivity; Seebeck coefficient; electrical resistance; Clathrates; Ba8Ga16Ge30; waste heat recovery; semiconductors;

    Abstract : The modern, highly industrialized, society of today requires huge amounts of energy to function. This has resulted in a heavy dependence on the very energy efficient fossil fuels, a source of energy which of course is not infinite and we are slowly approaching the day when oil runs out.
