  2. 1. Experimental Design and Evaluation of Biocide Release from Microcapsules

    Author : Jonatan Bergek; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; microsphere; microscopic and macroscopic porosity; controlled release; internal phase separation method; Microcapsule; biocide; polyelectrolyte multilayer;

    Abstract : To protect a painted house façade from mold or algae, anti-growth agents are usually mixed in the paint. The protection of paint systems used in the past relied on heavy metals for protection and are banned today due to their negative impact on the environment. READ MORE

  4. 2. Effects of biocides and metals on antibiotic resistance: a genomic and metagenomic perspective

    Author : Chandan Pal; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Antibiotic resistance; biocide; metal; co-selection; metagenomics;

    Abstract : Background and aim: There is a concern that biocides and metals can co-select for antibiotic resistance. The aim of this thesis is to enhance our understanding of the roles of antibacterial biocides (e.g. antiseptics, disinfectants) and metals (e. READ MORE

  5. 3. Prevention of Biofilm Formation on Silicone Rubber Materials for Outdoor High Voltage Insulators

    Author : Sevil Atari Jabarzadeh; Sigbritt Karlsson; Ferruccio Doghieri; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High voltage insulator; silicone rubber; biofouling; biofilm; biocide; superhydrophobicity; self-cleaning; hierarchical roughness;

    Abstract : Microbial colonization on the surface of silicone rubber high voltage outdoor insulators often results in the formation of highly hydrated biofilm that influence the surface properties, such as surface hydrophobicity. The loss of hydrophobicity might lead to dry band formation, and, in the worst cases, flashover and failure of the insulator. READ MORE

  7. 5. Occurrence and environmental risk assessment of antifouling paint biocides from leisure boats

    Author : Maria Lagerström; Ann-Kristin Eriksson Wiklund; Erik Ytreberg; Kent Salo; Andrew Turner; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antifouling paint; XRF; leisure boat; recreational boating; copper; zinc; tributyltin; organotin compounds; risk assessment; biocide; metals; release rate; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The use of biocidal antifouling (AF) paints is the most common way to prevent fouling on leisure boat hulls. The main aim of this thesis was to investigate the pathways through which AF biocides, past and present, may reach the environment through their use on leisure boats and to improve the risk assessment of biocidal AF paints intended for amateur use.
