  2. 1. Catalytic conversion of syngas to ethanol and higher alcohols over Rh and Cu based catalysts

    Author : Luis Gagarin Lopez Nina; Magali Boutonnet; Mario Montes Ramírez; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermochemical process; ethanol; higher alcohols; mesoporous catalysts; rhodium; copper; metal promoters; Chemical Engineering; Kemiteknik;

    Abstract : The thermochemical process converts almost any kind of biomass to a desired final product, i.e. gaseous or liquid transportation fuels and chemicals. The transportation fuels obtained in this way are renewable biofuels, which are alternatives to fossil fuels. READ MORE

  4. 2. On the role of Alkaline Earth Metal Oxides in Environmental Catalysis

    Author : Peter Broqvist; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In heterogeneous catalysis, metal oxides have various roles: as catalysts, as support material for catalytically active metal particles, as promoters, as stabilizers, or as storage materials. Although their main application is as support material, their role as promoter or storage material becomes increasingly important as emission legislations are becoming more stringent. READ MORE

  5. 3. Slurry Hydrotreatment of Biomass Materials over Metal Sulfide-based Supported and Unsupported Catalysts

    Author : You Wayne Cheah; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Hydrotreatment; Kraft lignin; Transition metals; Slurry hydrocracking; Propylguaiacol; Advanced biofuels; MoS2; Reaction network; Pyrolysis oil; Unsupported TMS;

    Abstract : The scarcity of fossil feedstocks and the deterioration of the current global climate condition have prompted the search for reliable alternatives for fossil fuel replacement. Biomass feedstocks are abundant, carbon-rich, and renewable bioresources that can be used to produce renewable bio-oils that can fill the gap left by fossil-derived oils. READ MORE

  6. 4. Statistical analysis of gene expression data

    Author : Erik Kristiansson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; gene expression; DNA microarrays; linear models; empirical Bayes; quality control; gene regulation; categorical data analysis; logistic regression; heavy metal stress; ecotoxicology; gene expression;

    Abstract : Microarray technology has become one of the most important tools for genome-wide mRNA measurements. The technique has been successfully applied to many areas in modern biology including cancer research, identification of drug targets, and categorization of genes involved in the cell cycle.
