    Abstract : This thesis is a summary and discussion of eight papers dealing with failures and structural aspects of Ni-Cd industrial pocket plate batteries, applications of voltammetry in adsorption studies on goethite (a-FeOOH) surfaces and synthesis and characterisation of nanostructured carbons. The work consists of different areas of chemistry; electrochemistry, structural chemistry and solution chemistry. READ MORE

  4. 2. 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

  5. 3. Processes of Magma-crust Interaction : Insights from Geochemistry and Experimental Petrology

    Author : Frances M Deegan; Valentin R Troll; Luigi Dallai; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Canary Island magmatism; HP-HT experimental petrology; magma-crust interaction; Merapi volcano; radiogenic isotopes Sr; Nd; Pb ; stable isotopes O; B .; Solid earth geology and petrology; Berggrundsgeologi och petrologi; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

    Abstract : This work focuses on crustal interaction in magmatic systems, drawing on experimental petrology and elemental and isotope geochemistry. Various magma-chamber processes such as magma-mixing, fractional crystallisation and magma-crust interaction are explored throughout the papers comprising the thesis. READ MORE

  7. 5. Nuclear Structure Studies near 208Pb and γ-ray Imaging Techniques

    Author : Natasa Lalovic; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nuclear structure; gamma-Ray spectroscopy; AGATA; isomeric decays; relativistic projectile fragmentation; Pb isotopes; nuclear structure; gamma-ray spectroscopy; AGATA; isomeric decays; relativistic projectile fragmentation; Pb isotopes;

    Abstract : This thesis focuses on a high-resolution γ-ray spectroscopy experiment where the fragmenta- tion of a 208 Pb primary beam was used to populate even-mass nuclei around 208 Pb. It was conducted in 2012 using the Advanced GAmma-ray Tracking Array (AGATA) while it was placed at GSI Darmstadt, Germany. READ MORE
