Air pollution and biomarker gases such as NO2, acetone, toluene, and ethanol. Novel material synthesis via sputter, hydrothermal, precipitation reaction, and sol-gel process. ZnO, In2O3, and Co3O4 based metal oxide materials. Set up of a measurement system for gas sensing performances. Systematic characterization through TEM, XRD, BET, P-E hysteresis, and so on.
