Abstract
Bioethanol is one of the alternative sources of oil resources which received attention with biodiesel. Many countries produce bioethanol from food sources such as corn and sugarcane, but it causes food-energy conflicts and farmland problem. So it needs to focus on new biomass which is sustainable, renewable, cost-effective and do not occurred any conflicts. Algae are one of the bioma
Characteristic of MOGS
1. Metal oxides possess electronic, chemical, and physical properties of high sensitivity to changes in their chemical environment.
2. The sensing properties of semiconductor metal oxide assures improved selectivity and stability
3. Their peculiar characteristics and size effects make them interesting for metal oxide gas sensors
