  1. 1. Hydrothermally induced changes of lean NOx reduction over Cu-ZSM-5 and stability improvements by synthesis modification

    Författare :Malin Berggrund; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydrothermal stability; Cu-ZSM-5; propene; lean NOx reduction; HC-SCR; in-situ DRIFT;

    Sammanfattning : The growing concern about the global warming coupled with the increasing emissions of the greenhouse gas carbon dioxide, combined with the climbing oil price, drives the interest to more fuel efficient lean combustion engines for automotive applications. Such engines require new technical solutions for reduction of NOx in the oxygen rich exhaust gases, where a conventional three-way catalyst cannot be used. LÄS MER

  2. 2. Identification and clinical implementation of biomarkers for cervical cancer

    Författare :Malin Berggrund; Ulf Gyllensten; Stefan Enroth; Matts Olovsson; Pär Sparén; Uppsala universitet; []
    Nyckelord :Cervical cancer; Human papilloma virus; Screening; Self-sampling; Biomarkers; Vaginal microbiota; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Introduction of organised screening programs and prophylactic vaccination against human papilloma virus (HPV) have successfully reduced the incidence of cervical cancer globally. In Sweden, the incidence has been reduced by about 50 % since the introduction of the national screening programme in the late 1960’s. LÄS MER

  3. 3. Studies of the influence of ZSM-5 synthesis on activity and stability of Cu-ZSM-5 in leand NOx reduction

    Författare :Malin Berggrund; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HC-SCR; Cu-ZSM-5; catalysis; propene; lean NOx reduction; hydrothermal stability;

    Sammanfattning : The growing concern about the global warming coupled with the increasing emissions of the greenhouse gas carbon dioxide, combined with the climbing oil price, drives the interest to more fuel efficient lean combustion engines for automotive applications. Such engines require new technical solutions for reduction of NOx in the exhaust gases, which are in excess oxygen, where a conventional three-way catalyst cannot be used to reduce NOx. LÄS MER
