  2. 1. Measurement and Control of Metal Vapours during Fluidized Bed Combustion of Biomass Fuels

    Author : Khanh-Quang Tran; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SI detector; metal capture; sorbent; Aalkali capture; TQ impactor; GQ probe;

    Abstract : Increased combustion of biomass fuels for heat and power production has created a need to recycle nutrient elements in biomass ash to soils to make the biomass consumption sustainable. It is, however, difficult to recycle the total amount of biomass ash produced due to the high concentrations of heavy metals and their readily soluble forms in some ash fractions. READ MORE

  4. 2. Modelling the Molecular World of Electrolytes and Interfaces : Delving into Li-Metal Batteries

    Author : Mahsa Ebadi; Daniel Brandell; Tejs Vegge; Uppsala universitet; []
    Keywords : Li-metal battery; solid polymer electrolyte; density functional theory; molecular dynamics simulation; solid electrolyte interphase;

    Abstract : Lithium metal batteries (LMBs) are potential candidates for powering portable electronic devices and for electromobility. However, utilizing the reactive Li metal electrode means tackling serious challenges in terms of safety risks. READ MORE

  5. 3. Cytokine responses in metal-induced allergic contact dermatitis : Relationship to in vivo responses and implication for in vitro diagnosis

    Author : Jacob Minang; Marita Troye-Blomberg; Niklas Ahlborg; Rik Scheper; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metal allergy; Contact dermatitis; cytokines; ELISA; ELISpot; Flow cytometry; Immunology; Immunologi;

    Abstract : Transition metals such as nickel (Ni), cobalt (Co), palladium (Pd), chromium (Cr) and gold (Au) are widely used as alloys in jewelry and biomaterials such as orthodontic and orthopaedic appliances. These metals also cause cell-mediated allergic contact dermatitis (ACD) reactions in a significant proportion of the population upon prolonged direct exposure. READ MORE

  6. 4. CO2 Capture using Chemical-Looping Combustion – Operational Experience with Gaseous and Solid Fuels

    Author : Carl Johan Linderholm; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nickel oxide; coal; natural gas; chemical-looping combustion CLC ; oxygen carrier; CO2 capture; manganese ore; interconnected fluidized beds; ilmenite;

    Abstract : CO2 capture and storage has been proposed as an alternative to mitigate global warming. Chemical-looping combustion (CLC) is an unmixed combustion concept where fuel and combustion air are kept separate by means of an oxygen carrier, and the CO2 capture is inherently achieved.

  7. 5. Synthesis and Applications of Colloidal Zeolites and Transition Metal Functionalized Ordered Mesoporous Carbons

    Author : Walter Rosas Arbelaez; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; colloidal zeolites; CO2 capture; hierarchical zeolites; growth mechanism; Fe-N-doped ordered mesoporous carbon; fuel cell.;

    Abstract : Porous materials have attracted a great deal of attention of the materials science community, owing to their physical and chemical properties including high surface areas, narrow pore size distribution, tunable pore diameters and variety of chemical compositions. These properties make them suitable for various applications such as adsorption, sensing, catalysis, energy, carbon capture and drug delivery. READ MORE
