16. Spatially resolved gas sensing
Sammanfattning : By using a Scanning Light Pulse Technique (SLPT) the gas response of catalytic Metal-Insulator semiconductor (MIS) devices can be spatially resolved.The application of SLPT to gas sensitive MIS devices can be divided into two areas. LÄS MER
17. Mechanical Gas Flow Sensors based on silicon micromachining
Sammanfattning : .... LÄS MER
18. SiC-FET Gas Sensors Developed for Control of the Flue Gas Desulfurization System in Power Plants Experimental and Modeling : Experimental and Modeling
Sammanfattning : 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. LÄS MER
19. Development of high temperature SiC based field effect sensors for internal combustion engine exhaust gas monitoring
Sammanfattning : 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. LÄS MER
20. Gas discrimination for mobile robots
Sammanfattning : The problem addressed in this thesis is discrimination of gases with an array of partially selective gas sensors. Metal oxide gas sensors are the most common gas sensing technology since they have, compared to other gas sensing technologies, a high sensitivity to the target compounds, a fast response time,they show a good stability of the response over time and they are commercially available.
