  2. 1. Investigation of vanadium-containing oxide systems : CALPHAD and experiments

    Author : Yang Yang; Malin Selleby; Caisa Samuelsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calphad; thermodynamic modelling; compound energy formalism; evaporation kinetics; activation energy; TGA; activity;

    Abstract : Fundamental studies on thermodynamic properties of vanadium-containing oxides systems are essential to understand practical vanadium metallurgical process. The CALPHAD technique is here applied to the thermodynamic modelling of the V-O, Ca-V-O and Ti-V-O systems. The compound energy formalism is used for all the solution phases. READ MORE

  4. 2. The in vivo metabolism of Benzo(a)pyrene studied by chromatography in combination with mass spectrometry

    Author : Yang Yang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Polycyclic aromatic hydrocarbons (PAHs) constitute a large class of chemicals with widespread occurrence in the environment. It is essentially impossible to avoid exposure to these substances on a daily basis. READ MORE

  6. 4. Phytoplankton and Physical Disturbance : Seasonal dynamics in temperate Lake Erken, Sweden

    Author : Yang Yang; Kurt Pettersson; Peeter Nõges; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phytoplankton dynamics; high-frequency measurements; thermal stratification; water column stability; equilibrium; disturbance;

    Abstract : Phytoplankton mirrors changes in the environment and plays an important role in biogeochemical processes. Phytoplankton dynamics is the outcome of both autogenic succession and external disturbances. READ MORE

  7. 5. Sustainable valorization of Biomass into Syngas/H2 via Biocarbon catalyst

    Author : Hanmin Yang; Weihong Yang; Pär Jönsson; Linda Sandström; Chunfei Wu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; Catalytic upgrading; Biomass; Biochar; Syngas; Hydrogen; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : Environmental issues stemming from the rapid growth in global energy demand and carbon dioxide emissions require urgent resolutions. Biomass represents a viable alternative for displacing fossil fuels, as its energy can be converted into electricity, heat, fuels, and chemical precursors, thus substituting petrochemicals. READ MORE
