1. Investigation of vanadium-containing oxide systems : CALPHAD and experiments
Sammanfattning : 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. LÄS MER
2. The in vivo metabolism of Benzo(a)pyrene studied by chromatography in combination with mass spectrometry
Sammanfattning : 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. LÄS MER
3. Measuring Socioeconomic Status and its Effects at Individual and Collective Levels: A Cross-Country Comparison
Sammanfattning : .... LÄS MER
4. Phytoplankton and Physical Disturbance : Seasonal dynamics in temperate Lake Erken, Sweden
Sammanfattning : 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. LÄS MER
5. Sustainable valorization of Biomass into Syngas/H2 via Biocarbon catalyst
Sammanfattning : 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. LÄS MER
