This talk will present an overview of a multidisciplinary research effort in ceramic-based chemical sensors highlighting opportunities as well as challenges. While there are exciting possibilities in nano-ceramics and thin films, there are problems associated with selectivity and long-term durability of these sensors in real-life applications. Particular emphasis will be given on the development of combustion gas sensors for pollution monitoring and control. Field-test results of these sensors in automobile engines will be presented. As a future direction, the talk will highlight a very inexpensive process for creating nano-structures in ceramic oxides that has potential for applications in chemical sensing and catalysis.
Summary: This talk will present an overview of a multidisciplinary research effort in ceramic-based chemical sensors by highlighting opportunities as well as challenges. While there are exciting possibilities in nano-ceramics and thin films, there are problems associated with the selectivity and long-term durability of these sensors in real-life applications. Particular emphasis will be given on the development of combustion gas sensors for pollution monitoring and control. Field-test results of these sensors in automobile engines will be presented. The talk will also highlight two future directions: (i) a novel approach for understanding the behavior of electrodes used for sensors and fuel cells and (ii) a very inexpensive process for creating nano-structures in ceramic oxides that has potential for applications in chemical sensing and catalysis.
