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

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

    Abstract : 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. READ MORE

  2. 2. Impacts of Antifouling Compounds on Photosynthesis, Community Tolerance and psbA Genes in Marine Periphyton

    Author : Martin Eriksson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PICT; antifouling; periphyton; photosynthesis; D1; psbA; tolerance; resistance; periphyton;

    Abstract : Toxicants can act as selective pressures in the environment, eliminating sensitive genotypes or species and favouring tolerant ones. Such toxicant-induced selection can be detected in natura... READ MORE

  3. 3. Bioactive Compounds in the Chemical Defence of Marine Sponges : Structure-Activity Relationships and Pharmacological Targets

    Author : Erik Hedner; Lars Bohlin; Per R Jonsson; Raffaele Riccio; Uppsala universitet; []
    Keywords : Pharmacognosy; 5-hydroxytryptamine; agelasine; agelasimine; antibacterial; antifouling; barettin; bromobenzisoxazolone barettin; cytotoxic; marine; secondary metabolite; sponge; Farmakognosi; Agelas; Geodia barretti;

    Abstract : Marine invertebrates, in particular sponges, represent a source of a wide range of secondary metabolites, many of which have been attributed various defensive capabilities against environmental stress factors. In this thesis sponge-derived low-molecular peptide-like compounds and associated analogs are investigated for bioactivity and pharmacological targets. READ MORE

  4. 4. Studies of fish responses to the antifoulant medetomidine

    Author : Anna Lennquist; Göteborgs universitet; []
    Keywords : antifouling; fish; medetomidine; ecotoxicology; biomarker;

    Abstract : ABSTRACT Growth of marine organisms, fouling, on man-made constructions submerged in the water is regarded as a major problem. For vessels, fouling increases drag and thereby fuel consumption, wherefore antifouling paints are used. Traditionally, they contain toxic compounds, and several of these have unwanted effects in the environment. READ MORE

  5. 5. Nanopolysaccharide coatings for functional surfaces in water-treatment materials : From mechanisms to process scalability

    Author : Andrea Aguilar Sánchez; Aji P. Mathew; Albert Mihranyan; Stockholms universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanopolysaccharides; coating; water treatment; nanocellulose; nanochitin; antifouling; antibacterial; separation technologies; materialkemi; Materials Chemistry;

    Abstract : In this thesis, materials from renewable resources were used to develop functionalized surfaces for water treatment. The work is thus inspired by, and contributes to, the United Nations sustainable goals of: (i) clean water and sanitation, (ii) climate action, (iii) responsible consumption and production, (iv) life below water, and (v) partnerships for the goals.
