  1. 6. Thermoplasmonic Effects in Microfluidic Systems

    Författare :Steven Jones; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; thermometry; thermoplasmonic bubbles; thermoplasmonics; plasmonics; thermophoresis;

    Sammanfattning : The field of plasmonics has enabled a plethora of scientific achievements over the past few decades. Such advances have been the result of the increased light-matter interaction that occurs over nanoscale dimensions facilitated by the localized plasmonic resonances supported by noble metal nanoparticles.

  3. 7. Proton conductivity of lanthanum and barium zirconate: Microscale aspects on first-principles basis

    Författare :Joakim Nyman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; first principles; trapping; conductivity; grain boundary; segregation; pyrochlore; space charge; solid oxide fuel cell; depletion; electrolyte; La2Zr2O7; oxygen vacancy; BaZrO3; proton; DFT; point defect; perovskite; acceptor;

    Sammanfattning : Fuel cells are devices which convert chemical energy into electrical energy cleanly and efficiently. Development of fuel cells compatible with hydrocarbon fuels would make more efficient use of present fossil and renewable fuels, and also enable progress towards a future hydrogen economy. LÄS MER

  5. 9. Proton trapping in the cellular acidic vacuolar compartment : lysosomal mechanisms in apoptosis/necrosis and iron chelation

    Författare :Zhengquan Yu; Anders Isaksson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Under ischemic conditions, a number of cytotoxic metabolic products are formed. Reactive oxygen species are known to be important mediators of progressive ischemic cell injury, and the synergistic damage to cells caused by the combination of such oxygen species and redox-active iron is well appreciated.

  7. 10. Effects of landscape patterns on small mammal abundance

    Författare :Frauke Ecke; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Landscape Ecology; Landskapsekologi;

    Sammanfattning : Several studies indicate a long-term decline in the numbers of voles in northern Fennoscandia. Altered land use and forest management practices have been proposed as possible causes of the decline. LÄS MER
