    Abstract : Electricity and power generation is an essential part of our life. However, powergeneration activities also create by-products (such as sulphur oxides, nitrogen oxides,carbon monoxide, etc), which can be dangerous when released to the atmosphere. READ MORE

  2. 2. Development of high temperature SiC based field effect sensors for internal combustion engine exhaust gas monitoring

    Author : Helena Wingbrant; Anita Lloyd-Spetz; Karin Larsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; field effect sensor; gas detection; selective catalytic reduction; lambda; cold start; ammonia; silicon carbide; engine exhaust.; Physics; Fysik;

    Abstract : While the car fleet becomes increasingly larger it is important to lower the amounts of pollutants from each individual diesel or gasoline engine to almost zero levels. The pollutants from these engines predominantly originate from high NOx emissions and particulates, in the case when diesel is utilized, and emissions at cold start from gasoline engines. READ MORE

  3. 3. SiCFET gassensors : theory, developent, and applications to flue gas cleaning processes  in power plants

    Author : Zhafira Darmastuti; Anita Lloyd Lloyd Spetz; Lars Ojamäe; Mike Andersson; Niclas Lindqvist; Mikael Larsson; Jaco Visser; Linköpings universitet; []
    Keywords : ;

    Abstract : Environmental and health concerns lead to stricter regulations on power plant emission. Sensors play an important role, not only as part of the process control to ensure that the effluent stays under the regulated values, but also to increase the pollution removal efficiency and to decrease the reagent consumption.

  4. 4. Selectivity Enhancement of Gas Sensitive Field Effect Transistors by Dynamic Operation

    Author : Christian Bur; Anita Lloyd Spetz; Andreas Schütze; Mike Andersson; Stephen Semancik; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Gas sensitive field effect transistors based on silicon carbide, SiC-FETs, have been applied to various applications mainly in the area of exhaust and combustion monitoring. So far, these sensors have normally been operated at constant temperatures and adaptations to specific applications have been done by material and transducer platform optimization. READ MORE
