  1. 11. Development of Kraft Lignin and Coating Technique to Prepare Coated Urea Fertilisers with Increased Nutrient Use Efficiency

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Xueyan Xu; [2017]
    Nyckelord :fertilizer coating; lignin; modified lignin; polylactide; slow release; ytbeläggning för gödningsmedel; lignin; modifierad lignin; polylaktid; kontrollerad frisättning;

    Sammanfattning : Coating urea to prepare controlled release N-fertilizer has been considered as an effective way to increase its nutrient use efficiency, thus reduce its waste and the consequent harmful environmental impacts. Inorganic sulphur and synthetic polymers have been used in the industry as coating materials together with utilization of various types of expensive coating equipment which commonly requires also complicated technical setup and controls.

  4. 13. Means for Serendipitous Discovery in the Innovation Process. How organizations can harness serendipity through idea management system

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Andreea Liana Bobirnea; [2014-12-15]
    Nyckelord :;

    Sammanfattning : “While serendipity is generally considered a spark for innovation and new knowledge, the triggers for serendipity appear infinite and consequently information systems' support for serendipity has been difficult to realize.” (Mccay-Peet, 2013) UK Research Council funds a project of 1,87 million Pounds aimed at understanding the role that serendipity plays in research and innovation in the digital economy.

  5. 14. Time of Flight Spectroscopy of Photon Migration in Turbid Media

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Författare :Johanna Paulsson; [2014]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Light interacting with biological matter is dominated by light scattering; biological matter is turbid. In order not to harm the natural structure of biological matter, visible light can be used to investigate it, and to avoid the light being absorbed from e.g. LÄS MER

  7. 15. Dielectrophoresis (DEP) and electrowetting (EWOD) as Anti-fouling processes for antibacterial surfaces

    Master-uppsats, KTH/Mikro- och nanosystemteknik

    Författare :Alberto Stavros Yika Tuesta; [2014]
    Nyckelord :DEP; EWOD; anti-fouling methods; antibacterial;

    Sammanfattning : Today the medical field is struggling to decrease bacteria biofilm formation which leads to infection. Also, biomedical devices sterilization has not changed over a long period of time which has resulted in high costs for hospitals healthcare managements. LÄS MER
