Nanostructured thin films of Ba-doped indium oxide have been examined for monitoring ppm levels of NOx in ambient air, and their response patterns have been recorded at different operating conditions. These films are found to be capable of sensing down to 0.5 ppm NOx concentration in air. The optimum operating temperature for sensing is found to be 300°C. Response and retrace times are ...
Measurements of car exhaust gases were made in May/June 1995 in the vicinity of the Bielefeld tunnel. CO and NOx from car exhausts were measured to allow comparison with a model simulation. ...
