  1. 1. 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. 2. Radially global neoclassical transport in tokamak pedestals

    Författare :Stefan Buller; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tokamak; transport; global effects; collisional transport; fusion; drift-kinetics; plasma physics;

    Sammanfattning : Nuclear fusion has the potential to become a sustainable energy sourcein the foreseeable future. The most developed system for fusion powerproduction is the tokamak, which magnetically confines a plasma at highenough temperature for fusion reactions to take place. LÄS MER

  4. 3. Characterization of Carbon Oxidation Kinetics for Particulate Matter Reduction Technologies

    Författare :Carolin Ohlson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heterogeneous catalysis; Carbon – catalyst interaction; Soot oxidation; Particulate filter; Carbon oxidation; Global kinetics; Regeneration; Particulate matter oxidation; DPF;

    Sammanfattning : Transport related emissions of particulate matter (PM) represent a significant health risk and are therefore strictly regulated in most developed countries. An efficient technique to reduce emissions of combustion particles is to capture the particles in a filter, which must be subsequently regenerated by oxidation of the carbonaceous fraction of the PM.

  5. 4. Optimisation Challenges in Pressurised Hot Water Extraction of Polyphenols: Extraction and Degradation Kinetics

    Författare :Jiayin Liu; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Extraction kinetics; degradation kinetics; pressurised hot water extraction; optimisation; and anthocyanins; flavonoids; and polyphenols;

    Sammanfattning : Pressurised hot water is an environmentally friendly alternative to hazardous organic solvents such as methanol and heptane. One of the many applications of using pressurised hot water extraction (PHWE) is to extract polyphenols from plants. The challenges in PHWE lies with the optimisation of extraction yield. LÄS MER

  7. 5. Infection kinetics, phylogenetics, and host interactions of bacteriophages

    Författare :Shazeeda Koonjan; Anders S. Nilsson; Lone Brøndsted; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bacteriophage biology; infection kinetics; phylogenetics; host interactions; phage therapy; phage ecology and evolution; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Bacteriophages, or as they are most commonly referred to as phages, are viruses which are capable of infecting bacteria. They are environmentally plenty, found everywhere from the ground we walk on to contributing to our microbiome. They are highly diverse, coming in various sizes, shapes, and genomic compositions.
