    Författare :Parviz Pourghahramani; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : The mechanical treatment of solids is one of the most common and widely used operations which man has been concerned from the very beginning of the history of civilization. Nowadays, mechanical activation has a wide range of application potentials. LÄS MER

  5. 5. Synthesis and characterization of zeolite films and membranes

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Magdalena Gualtieri; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemisk teknologi; Chemical Technology;

    Sammanfattning : In this work, a seeding technique was used to synthesize films and membranes of FAU, LTA and MFI type zeolites. In the first part, hydrothermal growth was performed without organic template molecules, which resulted in template-free zeolite films and membranes. LÄS MER
