  2. 1. Inhibition of Aluminium Pigments for Waterborne Coatings

    Author : Philip Karlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen evolution; AFM; surfactant; aluminium pigment; polymer; silica stabilisation; water based; adsorption; inhibition; waterborne; printing ink; QCM-D; AAS; reflectometry; encapsulation; paint; metallic pigment; coating; XPS;

    Abstract : Micrometer-sized aluminium flakes for use as pigments in waterborne coatings need protection, since the reaction between aluminium and water causes formation of aluminium hydroxide and hydrogen gas. The aluminium hydroxide destroys the metallic appearance of the pigment flakes and the evolution of hydrogen gas leads to a dangerous pressure build-up in the paint containers. READ MORE

  4. 2. Bioaccessibility, corrosion and surface properties of metals, alloys and metallic powder in biological fluids of relevance for occupational and consumer health hazard assessment

    Author : Xuying Wang; Inger Odnevall Wallinder; Yolanda S. Hedberg; Lars Nyborg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metal and alloy; metal release; synthetic biological fluids; surface oxide; corrosion resistance; hazard assessment; Kemi; Chemistry;

    Abstract : When assessing hazards of metals, alloys, and metal-containing items, the metal release (bioaccessibility) is of high importance. Triggered by increasingly stricter hazard classifications for metals, especially cobalt (Co), and limited knowledge, the aim of this doctoral thesis is to assess correlations between the metal/alloy surface characteristics, corrosion and metal release pattern in different simulated biological fluids relevant to human exposure scenarios (dermal, ingestion and inhalation, Papers I-V).

  5. 3. Red Glass Coloration : a Colorimetric and Structural Study

    Author : Torun Bring; Lars Kloo; Alicia Duran; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi;

    Abstract : Syftet med detta arbete har varit att försöka hitta alternativ till det kadmiumbase¬rade röda pigment som används idag. Detta har gjorts genom att delvis under¬söka kombinationer av grundämnen som i litteraturen finns omnämnda som röda glaspigment, delvis genom att försöka förbättra och underlätta produktionen av redan kända, men problematiska pigment.
