Discharge electricity?
->No need to charge
Low temperature operation?
-> Min. 600 ℃
Only H2 for fuel?
-> Carbohydrates
Stable at high T and oxidation-reduction condition
High ionicconductivity
Low electronic conductivity
Perovskite or Flourite structure
Chemical stability at reduction environment
There is no change of state between normal T and operating T
potential,
begin to exchange ions
this makes maximum strain limit
Advantages of CNT as an actuator
- High output stress (work)
- Actuatable at high temperature (> 100℃ - ionic liquid)
- Double layer charge effect
long life-cycle (than conducting polymer)
Disadvantage
Low electrochemical strain (< 1%)
(than conducting polymer – polypyrrole 26%)
Writing Net Ionic Equations
Write the balanced molecular equation.
Write the ionic equation showing the strong electrolytes completely dissociated into cations and anions.
Cancel the spectator ions on both sides of the ionic equation
Check that charges and number of atoms are balanced in the net ionic equation
Write the net ionic equation for the reaction of silver nitrate with sodium ch
ionic or heavy metal contaminants.
The RCA clean procedure should be performed immediately prior to any crucial step, especially those involving high temperatures. For safety reasons, all activities in the RCA clean procedure should be performed in a Clean Station Work Area which is located under an exhaust fume hood.
