    Sammanfattning : Gasfasympning är en del i den moderna strategin för optimering av den molekylära designen av biomaterial. Kovalent ytmodifiering med hydrofila vinylmonomerer och koppling med bioaktiva grupper används för att öka biokompatibiliteten och bioaktiviteten hos biomaterialen.. LÄS MER

  7. 20. Separation of plastics by flotation

    Författare :Huiting Shen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : This thesis analyses and summarises the importance of plastics waste recycling and plastics waste separation, presents an innovative principle for plastics flotation, and provides various methods for the separation of plastics mixtures. The objective is to understand the mechanisms for selective flotation separation of plastics, get plastics mixtures separated and enable more plastics wastes to be recycled. LÄS MER
