    Abstract : Today the importance of solar cells as a power source is growing due to the environmental advantages compared to fossil fuels. One of the most promising new solar cell materials, resulting in high efficiency solar cells, is copper indium gallium selenide (CIGS). READ MORE

  5. 3. Recycling of TiO2 Pigments from Waste Paint: Process Development, Surface Analysis, and Characterization

    Author : Mikael Karlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recycling; Recovery; Paint; Titanium dioxide; Waste.; Municipal solid waste handling; Pyrolysis; Pigment;

    Abstract : Pigments are commonly used in paint, plastic and paper products and titanium dioxide (TiO2), the most important white pigment, accounts for approximately 70 % of the total volume of all pigments used today. Minerals containing TiO2 are relatively abundant in the earth’s crust. READ MORE

  6. 4. Long-term Properties of Sustainable Polymeric Materials : Mechanical Recycling and Use of Renewable Resources

    Author : Emma Strömberg; Sigbritt Karlsson; Amparo Ribes-Greus; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sustainable materials; mechanical recycling; polyolefin; reprocessing; accelerated ageing; chromatography; biofilm; microenvironment chamber; environmental degradation; biocomposite; nanocomposite; Polymer chemistry; Polymerkemi;

    Abstract : New strategies for management of the accumulating amounts of plastic waste are required, to achieve a sustainable development in terms of material production and use. After service life, the materials should be recovered and recycled efficiently to provide a valuable resource for future applications. READ MORE

  7. 5. Electric DNA arrays for determination of pathogenic Bacillus cereus

    Author : Yanling Liu; Sven-Olof Enfors; Helena Anderson; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bacillus cereus; haemolysin; non-haemolytic enterotoxin; cytotoxin K-2; cereulide; toxin-coding genes; bacterial colony; electric DNA chip; ultrasonication; DNA fragmentation; Biochemistry; Biokemi;

    Abstract : Silicon-based electric chip arrays were developed for characterization of Bacillus cereus with respect to the capacity to produce toxins involved in food poisoning and foodborne infections. Bacteria of the B. cereus group contain different sets of four toxins encoded by eight genes. READ MORE
