  1. 1. Development of Polyamide Solvent Extraction Reagents for Trivalent Lanthanides

    Författare :Mikhail S Tyumentsev; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Polyamides; Solvent Extraction; Europium; Rare Earth Elements; Lanthanides; Malonamides;

    Sammanfattning : Rare earth elements (REEs), including lanthanides, are critical materials for many industrial technologies. As a result recycling of end-of-life products containing REEs might be beneficial, as this could partially satisfy the growing demands of industry for these elements. LÄS MER

    Sammanfattning : Shortages of fossil fuel and other political movements contributed to the nuclear energy “renaissance”.Nuclear energy, however, is not free of challenges, one of them being nuclear waste management. LÄS MER

  5. 5. Tailoring of Transition Metal Silicides as Protective Thin Films on Austenitic Stainless Steel

    Detta är en avhandling från ; Department of Chemistry, Swedish University of Agricultural Sciences

    Sammanfattning : The objective of this study is to make use of transition metal silicides in a novel way as protective thin films on engineering metals. It can then be possible to take advantage of the potentially good corrosion resistance of metal silicides while compensating for their brittle nature by the ductile bulk material. LÄS MER
