  1. 11. Pyrolysis profiles and global kinetics of tropical biomass : coconut and cashew nut shells

    Författare :Alberto Júlio Tsamba; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermogravimetry; cashew nut cocnut shells; pyrolysis; kinetics; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : Biomass has been recognised as renewable and environmentally friendly source of energy since decades. Tropical biomasses which are available in large quantities as residues in Latin America, Africa and Asia, have high energy potential for exploitation through thermochemical conversion process, as pyrolysis, gasification or combustion.

  3. 12. Char conversion kinetics and aerosol characterization in biomass gasification

    Författare :Leteng Lin; Michael Strand; Alberto Gómez-Barea; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass gasification; fluidized bed; char; kinetics; aerosol; APS; TEOM; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology;

    Sammanfattning : Biomass gasification is a thermochemical conversion by partial oxidation at elevated temperature of solid biomass into a gaseous energy carrier. The product gas contains the major components CO, H2, CO2, CH4, as well as some tar and inorganic impurities and solid particles such as ash, bed material, soot and char. LÄS MER

  4. 13. Initial Oxidation Kinetics of Al(111): A Monte Carlo Study

    Författare :Dogan Ergun Oner; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxide nucleation and growth; dissociative adsorption; metal oxidation; Monte Carlo simulations; Al 111 ; kinetics; aluminium; surface oxidation;

    Sammanfattning : Almost all metals around us have a thin oxide layer on top of the bulk metal underneath. Often this oxide film protects the metal against further oxidation, or corrosion. Examples are the oxide film that makes stainless steel "stain-less" or the ones on titanium and aluminium alloys, which are very corrosion resistant. LÄS MER

  5. 14. In Vitro Kinetics of Ribosomal Incorporation of Unnatural Amino Acids

    Författare :Jinfan Wang; Anthony Forster; Jason Chin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ribosome; protein synthesis; unnatural amino acids; kinetics; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Sammanfattning : Ribosomal incorporation of unnatural amino acids (AAs) into peptides or proteins has found broad applications in studying translation mechanism, discovering potential therapeutics, and probing protein structure and function. However, such applications are generally limited by the low incorporation efficiencies of the unnatural AAs. LÄS MER

  7. 15. Amyloid beta aggregation kinetics : The role of intrinsic and extrinsic factors

    Författare :Xiaoting Yang; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alzheimer s disease; Abeta; aggregation; kinetics; secondary nucleation;

    Sammanfattning : Cerebral senile plaque is one of the main pathologies of Alzheimer's disease (AD). The amyloid cascade hypothesis suggests that the aggregation of amyloid beta (Abeta) peptide is involved in the pathogenesis of AD, which is supported by the fact that Abeta overexpression or production of more aggregation-prone variants lead to early-onset dementia.
