  1. 11. Geochemical processes in mine waste subjected to a changing chemical environment: Fe speciation in leachate water from column experiments

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Paula Lundberg; [2017]
    Keywords : Sulfidic mine waste; Sulfide oxidation; Water quality; Environmental analytical chemistry; Iron redox speciation;

    Abstract : Oxidation of sulfidic mine waste is of significant environmental concern due to the consequent formation of acid rock drainage (ARD), deteriorating the water quality of natural water systems. Iron (Fe) and sulfur (S) are two major redox elements involved in these reactions and typically the major redox-sensitive elements (whose solubility, speciation, and mobility are affected by pH and Eh) in water affected by ARD.

  3. 12. Development of a wear index and its methodology related to mineral processing - Part I

    University essay from Lunds universitet/Industriell Produktion

    Author : André Larsson; [2016]
    Keywords : Nanoindentation; Berkovich indenter; wear; surface hardness; rock; minerals; manganese steel; mining; comminution.; Technology and Engineering;

    Abstract : This Master Thesis was performed for Sandvik SRP in collaboration with the Institution for Industrial Production Faculty of Engineering at Lund University. Tool wear is one of the main cost drivers in the mining industry. READ MORE

  4. 13. X-Ray Photoemission Spectroscopy Characterization of Fe(II)- and Fe(III)-Phthalocyanine Molecular Films

    University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Author : Sonja Droschke; [2015]
    Keywords : iron phthalocyanine; FePcCl; iron phthalocyanine chloride; XPS; photoelectron spectroscopy;

    Abstract : This thesis investigates the electronic structure of iron phthalocyanine (Fe(II)Pc) andiron phthalocyanine chloride (Fe(III)PcCl) immobilized on surfaces. For this purposetwo different deposition methods are used and compared: smearing the molecularpowder under atmosphere condition and evaporation of a molecular layer inultra-high vacuum. READ MORE

    Abstract : Master essäen publicerades som bok och var tillgänglig på utställningen 'Beyond Zero'. Performancet 'Spending time to draw Time utfördesvarje gång någon ville ha en kopia. I performancet ritar jag en punkt efter \"Frozen time=\" och en linje efter \"Time\" på sidorna 20-21. Jag änvänder min egen tid för att rita \'tid\'. READ MORE

  6. 15. Determining the effective temperature of cool stars from near-infrared spectra

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Henrik Rhodin; [2015]
    Keywords : Physics and Astronomy;

    Abstract : Context. Effective temperature is one of the fundamental stellar parameters. A traditional spectroscopic way to determine it is from optical spectra using excitation balance of Fe-lines. READ MORE
