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
The reason we take Nox as targe

Gas, van der Waals, Redlich-Kwong 이 세 가지 EOS가 나오게 된 배경과 그 유도과정 과정, 차이점, 각각의 Parameter a, b를 구하는 방법을 조사해 기술하였고, MATLAB 프로그램을 활용, Ethylene Oxide의 각 EOS에 대해 P, V, T의 거동의 실제 시각적인 자료, 즉, PV Diagram을 만들어 예상한 것과 일치하는지 확인해보는 작업을 하
Sulfur Dioxide(SO2)
The release of SO2 to the atmosphere is the primary cause of acid rain in the world.
Fossil fuel combustion at electric power-generating plants accounts for about70% of
the emissions.
Coal, Oil, and all other fossil fuels naturally
contain some sulfur.
Volcanic eruptions are another more localized natural source of SO2
SO2 + OH. HSO3.
