  6. 4. Equilibrium studies of ternary aluminium(III) hydroxo complexes with ligands related to conditions in natural waters

    Author : Lars-Olof Öhman; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aqueous solution; binary and ternary hydroxo complexes of Al3 ; carbonic acid; citric acid; phenolic ligands; emf-titrations; equilibrium analysis; model calculations towards natural waters;

    Abstract : The thesis is a summary and discussion of eight papers. During the last decades, precipitation has become increasingly acidic due to the extensive use of fossil fuels. In areas of poorly buffered bedrocks, e.g. READ MORE

  7. 5. EMF Exposure and Radiation Performance of Millimeter-Wave Antennas in 5G Mobile Terminals

    Author : Bo Xu; Sailing He; Oscar Quevedo-Teruel; Akimasa Hirata; KTH; []
