    Sammanfattning : Gels are weak, solid-like structures that arise when colloidal particles aggregate to form a network of particle clusters. A variety of colloidal systems that are important scientifically as well as in industrial applications are capable of gel formation, e.g. globular protein solutions, colloid-polymer mixtures, and metal oxides.

    Sammanfattning : Perovskite based materials have great potentials for various energy applications and the search for new materials for uses in SOFCs has largely been concentrated to this class of compounds. In this search, we have studied perovskite phases in the system La2Co1+z(Ti1-xMgx)1-zO6, with 0  x 0.9 and z = 0.0, 0. LÄS MER

  5. 4. Från Orfeus till Eurydike : en rörelse i samtida svensk lyrik

    Författare :Lena Malmberg; Litteraturvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; General and comparative literature; Bruno K. Öijer.; Jesper Svenbro; Birgitta Lillpers; Ann Jäderlund; Arne Johnsson; Katarina Frostenson; epiphany; poetry of mourning; contemporary Swedish poetry; elegy; Eurydice; Orpheus; literature criticism; literary theory; Allmän och jämförande litteratur; litteraturkritik; litteraturteori;

    Sammanfattning : The Orphic myth takes an important position through the history of poetry. Due to the cultural climate the myth has been assumed either to raise the position of the poet or to discuss the limitations of performed poetry. LÄS MER
