  2. 1. Phase transformation and surface chemistry of secondary iron minerals formed from acid mine drainage

    Author : Jörgen Jönsson; Lars Lövgren; Per Persson; Staffan Sjöberg; Douglas B Kent; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; schwertmannite; goethite; lepidocrocite; acid mine drainage; sulphate; natural organic matter; mineral surface; infrared spectroscopy; EXAFS; XRD; ternary surface complex; copper II ; cadmium II ; lead II ; zinc II ; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : The mining of sulphidic ore to extract metals such as zinc and copper produces huge quantities of waste material. The weathering and oxidation of the waste produces what is commonly known as Acid Mine Drainage (AMD), a dilute sulphuric acid rich in Fe(II) and heavy metals. READ MORE

  4. 2. 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.

  6. 4. Iron based Li-ion insertion materials for battery applications

    Author : Andreas Blidberg; Fredrik Björefors; Mats Johnsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Li-ion; battery; Li2FeP2O7; LiFeSO4F; PEDOT; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : Li-ion batteries are currently the most efficient technology available for electrochemical energy storage. The technology has revolutionized the portable electronics market and is becoming a corner stone for large scale applications, such as electric vehicles. READ MORE

  7. 5. Characterisation of Fuels and Fly Ashes from Co-Combustion of Biofuels and Waste Fuels in a Fluidised Bed Boiler. A Phosphorus and Alkali Perspective

    Author : Anita Pettersson; Högskolan i Borås; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; phosphorus recovery; co-combustion; fluidised bed combustion; olivine; Biofuels; zeolites; fertiliser; extraction; refuse derived fuels; kaolin; alkali; sulphur; ash; municipal sewage sludge;

    Abstract : In the efforts to create sustainable production of heat and power and to reduce the net CO2 emissions to the atmosphere, alternative fuels are today being utilised. These fuels are, for example, biofuels and waste derived fuels such as different residues from the agricultural sector and the pulp and paper industry, municipal sewage sludge and municipal sorted solid waste.
