The recent progress of researches on supercapacitors using carbon material, metal oxides and conducing polymer as electrode materials are described in this review paper.

The effect of sulfur oxides could be anticipated from the earlier experience in the acute smog episodes described above and from the studies in Great Britain and Japan.

Tighter rules will also be set for some pollutants already monitored, such as nitrogen oxides and PM10 (particulate matters smaller than 10 micrometers).

Metal oxides contain a metal cation and the oxide anion (O2-); they typically react with water to form Bases or with acids to form salts.
