At 800 °C and a KOH/MEGO mass ratio of 6.5, a maximum specific surface area of 3100 m2/g was obtained and a high specific capacitance of 172 F/g (at 1 A/g constant current and 3.5 V maximal voltage) was measured in a two-electrode cell with a-MEGO electrodes in an organic electrolyte.
For graphene FETs, the tunneling current through a 50-nm SiO2 layer at 3.5 V, which is the maximal gate-source voltage, is found to be 3 μA/cm2 [14].
Data were fitted to the Boltzmann equation GNa = [1+exp V1/2−V)/k]−1 where V1/2 is the half-maximal voltage, k is the slope factor, and the Na+ conductance GNa is defined by GNa = INa,norm/(V−Vrev).
The effect was more pronounced in the Ts65Dn mice, where the fast and slow current responses at the maximal voltage step were lower by about 35% of the diploid cells.
In addition, the force outputs of the actuator when voltage is on and off are acquired, which shows actuator has a maximal force ability of 1.6 N.
For each animal the voltage was increased until a maximal dilation was observed, the resulting current was monitored on an oscilloscope ranging between 100 and 160 μA.
Activation curves, determined from peak tail current normalized to the maximal value and plotted against the test pulse voltage, were fitted with Boltzmann equation (y=[1+exp{(V− V1/2)/ k}]−1), where V1/2 is the half-maximal voltage of activation, and k is the slope factor.
Voltage was increased in stepwise manner until maximal twitch response was evoked.
The voltage was adjusted from 3.0 to 9.0 V until maximal isometric torque was achieved.
