                         and deposition (PIII\&D). In the process, after the generation of

                         10 h, leading to the achievement of poly-crystalline ZnO 
                         nanostructures. The resistance change of the sensor was monitored 
                         by varying the respectiveworking temperature from 140 C up to 280 
                         C for three different acetylene concentrations (1, 2, 3 vol%).

                         recovery time was also measured and the repeatability of thesensor 
                         was tested by feeding and cutting the working gas supply into the
