   Sammanfattning : Increasing oil prices and concerns about global warming have reinforced the interest in biofuels for domestic and district heating, most commonly through combustion of solid biomass like wood logs, hog fuel and pellets. Combustion at non-optimal conditions can, however, lead to substantial emissions of noxious compounds like unburned hydrocarbons, carbon monoxide, and nitrogen oxides as well as the generation of soot.

3. 2. Materials design and characterization of the active regions of gas sensitive field-effect devices

   Författare :Anna Elisabeth Åbom; Udo Weimar; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Metal-Insulator-Semiconductor (MIS) field-effect devices with catalytic metal layers are sensitive to several important gases, such as hydrogen, ammonia, hydrocarbons and alcohols. The gas sensitivity and selectivity depends on the properties of the active regions of the device. LÄS MER
