1. Catalysts for Car Exhaust: Oxygen Storage in Platinum/Ceria and Mass Transfer in Monoliths
Abstract : In this work, the oxygen storage/release in Pt/ceria catalysts has been investigated both experimentally and theoretically. Moreover, the flow distribution and mass transfer in monolith catalysts for car-exhaust purification have been studied. READ MORE

3. Studies of MISiC-FET sensors for car exhaust gas monitoring
Abstract : The increasing size of the car fleet makes it important to find ways of lowering the amounts of pollutants from each individual diesel or gasoline engine to almost zero levels. The pollutants from these engines predominantly originate from emissions at cold start, in the case when gasoline is utilized, and high NOx emissions and particulates from diesel engines. READ MORE

4. Silicon carbide field-effect devices studied as gas sensors for exhaust gas monitoring
Abstract : Metal-insulator-silicon carbide (MIS) structures have been studied as gas sensors. We have investigated how the sensors detect gases, how fast they do that, and how they could be used for exhaust gas monitoring.We have prepared simple field-effect devices, MIS-capacitors and Schottky diodes, on silicon carbide with platinum gates.

5. Particle emissions from car brakes : The influence of contact conditions on the pad-to-rotor interface
Abstract : Due to their adverse health effects emissions have been regulated for over three decades. Brake wear particulate matter is the most important non-exhaust source, however current knowledge is mainly limited to observational studies. READ MORE
