  1. 1. Barnacle Bioadhesive Bonding Formation, Strength and Control

    Författare :Mattias Berglin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; barnacle adhesive plaque; poly dimethylsiloxane ; fouling release coatings; bioadhesion; marine biofouling;

    Sammanfattning : The current technology for keeping ship hulls free of marine biofouling requires the use of toxic compounds such as copper, organic biocides and tributyl tin (TBT). The compounds that are released have been shown to have negative effects on non-target organisms, and a worldwide ban of TBT is currently being introduced. LÄS MER

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

    Författare :Jan Sandberg; Inger Odnevall Wallinder; Dan Persason; KTH; []
    Nyckelord :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

  4. 3. Low biocide emission antifouling based on a novel route of barnacle intoxication

    Författare :Emiliano Pinori; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; antifouling; Barnacles; ivermectin; low biocide emission; marine fouling; marine paint; ISO 15181; ToF-SIMS;

    Sammanfattning : Marine biofouling can be defined as the colonization of man-made surfaces in seawater by microscopic and macroscopic organisms. This phenomenon can result in great loss of function and effectiveness both for cruising ships and for static constructions. LÄS MER

  5. 4. Flow effects on settlement and recruitment in the barnacle BALANS IMPROVISUS with applications for biofouling control

    Författare :Ann I. Larsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : An understanding of the processes causing patterns of organism distributions in time and space is fundamental in ecology. For sessile marine invertebrates, water motion is an important predictor of distribution patterns, affecting organisms all the way from dispersal to post-settlement recruitment. LÄS MER
