  2. 1. Tetradentate amide extraction agents for trivalent lanthanides

    Author : Mikhail S Tyumentsev; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; malonamides; lanthanides; solvent extraction; entropic effect; electrospray ionization – mass spectrometry; single-crystal X-ray diffraction;

    Abstract : Lanthanides are valuable materials. They are used in catalysts, permanent magnets, batteries, optical devices, and in many other products. Lanthanides are mainly supplied by mining industry, which generates large volumes of waste due to relatively low concentrations of these elements in geological deposits. READ MORE

  4. 2. Development of Polyamide Solvent Extraction Reagents for Trivalent Lanthanides

    Author : Mikhail S Tyumentsev; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Polyamides; Solvent Extraction; Europium; Rare Earth Elements; Lanthanides; Malonamides;

    Abstract : 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. READ MORE

  5. 3. Investigations of Solvent Systems Based on bis-triazine-bipyridine (BTBP) - class Ligands for the Separation of Actinides from Lanthanides

    Author : Teodora Retegan Vollmer; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; lanthanides; diluents; BTBP; solvent extraction; side groups; complexes; actinides;

    Abstract : 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. READ MORE

  6. 4. Extraction Properties of some Nitrogen-Containing Extractants and Determination of Nitrate Complex Formation for Lanthanides and Selected Actinides Using Solvent Extraction

    Author : Sofie Andersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; actinides; solvent extraction; separation; lanthanides; nitrate complex formation;

    Abstract : Partitioning and transmutation of spent nuclear fuel will reduce the amount of waste and its radiotoxicity in a long-term perspective. At the same time the energy content of the spent nuclear fuel can be used more efficiently by recycling of uranium and plutonium and by using energy from the transmutation reactor. READ MORE
