  2. 1. Towards Abatement of Selected Emissions from Metals Manufacturing

    Author : Diana Orrling; Seshadri Seetharaman; S. Subramanian; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mercury; zinc; iron; copper; sulfur dioxide; adsorption; pollution; spectroscopy; thermal desorption; polycrystalline; surfaces; Materials science; Teknisk materialvetenskap;

    Abstract : Although the metallurgical industry has made great strides in the reduction of unwanted emissions to the atmosphere as a result of production processes, significant challenges still exist. From a global perspective, even large reductions in emissions per produced ton become immaterial when considering that the total world production of metals continues to increase. READ MORE

  4. 2. Alkaline by-products as amendments for remediation of historic mine sites

    Author : Lotta Sartz; Bert Allard; Ernest Yanful; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oxidized mine waste; lime mud; green liquor dregs; fly ash; lime kiln dust; steel slag; water works granules; Oxiderat gruvavfall; mesakalk; grönlut; flygaska; filterkalk; stålslagg; vattenverksgranuler; NATURAL SCIENCES; NATURVETENSKAP; Environmental chemistry; Miljökemi; Enviromental Science; Miljövetenskap;

    Abstract : Mining has been and still is an important industry in Sweden, it has strongly contributed to the standard of living we have today. Extraction of ore began in the 12th century, but did not come about frequently until the 16th century, which is often seen as the starting age for ore processing and metal extraction. READ MORE

  5. 3. Investigation of Sintering Kinetics of Magnetite pellets during Induration

    Author : TK Sandeep Kumar; Lawrence Hooey; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : One of the measures of development and economy of a nation is its per capita consumption of steel, and the demand is fulfilled by iron ore. In the context of increasing environmental constraints and ores becoming leaner and leaner, recycling and utilization of ore fines becomes necessary. READ MORE

  6. 4. Controlling the mobility of organic carbon (OC) ant its impact on metal transport from incineration residues

    Author : Malin Svensson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Avfallsteknik; Waste Science and Technology;

    Abstract : Incineration residues contain both inorganic and organic material. The organic material may affect the mobility of pollutants in e.g. landfills or geotechnical constructions. READ MORE

  7. 5. Structure-Property Relationships of Iron N-Heterocyclic Carbene Complexes : Synthesis, Characterization and Application

    Author : Valtýr Freyr Hlynsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; photoredox catalysis; photovoltaics; photosensitizer; N-heterocyclic carbene NHC ; BHAS; synthesis; Organometallic chemistry; structure-property relationship; coordination chemistry; heteroleptic iron complexes; geometry; photophysics;

    Abstract : Resulting from the general availability of first-row transition metals, compared to their second- and third-row counterparts, photosensitizers (PSs) based on metals like iron have gained interest as candidates to enable photochemistry from solar energy, a largely underutilized energy source. Iron complexes equivalent to other metal complexes, currently being used as PS, do lack some of the advantageous properties required to challenge the established PSs. READ MORE
