  1. 1. Corrosion-induced release of zinc and copper in marine environments

    Författare :Jan Sandberg; Inger Odnevall Wallinder; Dan Persason; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; copper; zinc; marine environment; runoff rate; atmospheric corrosion; chloride deposition; anti-fouling paints; chemical speciation; bioavailability; cupric ions; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : This licentiate study was initiated by copper, zinc and galvanized steel producers in Europe, who felt a need to assess runoff rates of copper and zinc from the pure metals and commercial products at marine exposure conditions. Their motive was the increasing concern in various European countries and the on-going risk assessments of copper and zinc within the European commission. LÄS MER

  2. 2. Fouling in biomass fired boilers

    Författare :Jan Sandberg; Rebei Fdhila; Erik Dahlqvist; Alain Liné; Mälardalens högskola; []
    Nyckelord :Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : This thesis describes a detailed investigation into fouling in biomass fired boilers according to fuel mixture, combustion conditions, transportation of particles by the flue gas and the probability of particles impinging and sticking onto heat transfer tubes. The effects of fouling on overall boiler performance and the efficacy of soot blowing are also investigated. LÄS MER

  3. 3. Fouling in biomass fired boilers

    Författare :Jan Sandberg; Rebei Bel Fdhila; Erik Dahlqvist; Anders Nordin; Mälardalens högskola; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fouling; deposit; boiler; biomass; simulations; Thermal energy engineering; Termisk energiteknik; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : In order to reduce the discharge of the greenhouse gas CO2, the use of biomass is nowadays promoted as fuel in boilers. Compared to boilers fired with coal and oil the biomass-fired boilers have more complications related to both fouling and corrosion on the heat transfer surfaces. LÄS MER

  5. 5. On the Development of Mucin-based Biomaterial Coatings

    Författare :Tomas Sandberg; Karin Caldwell; Jan Carlsson; Thomas Arnebrant; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mucin; Biomaterial; Surface-exposed protein; XPS; Neutrophil; Cell morphology; SEM; QCM-D; Viscoelasticity; Protein-stabilization; HNL; Coating; MG1; BSM; PGM; SEC-MALS-RI; Mucin quantification; Protein adsorption; Ellipsometry; Biomaterials; Biomaterial;

    Sammanfattning : Owing to their key role in mucosal functioning as surface barriers with biospecific interaction potentials, the mucins are interesting candidates for use as surface modifiers in biomaterials applications. In this work, “mild” fractionation procedures were used to prepare mucins of bovine (BSM), porcine (PGM), and human (MG1) origin. LÄS MER
