[CuII bdmpza)2] can be oxidized at high potentials to form CuO, which was observed by a slight increase in catalytic current over time.
OK, their first cell is not yet up to the 16% efficiency, but there was a benefit: while the polymer based cells declined in current over time, the copper iodide ones did not.
Resistance degradation in perovskites is characterized by an increase in current over time with applied electric field.
Coulomb counting (i.e., integrating the battery current over time) is the most common method to calculate the charge remaining in the battery [32].
Each simulation case runs for 1 ns to reach a steady state, and then for 1.5 ns to average the temperature profile and heat current over time.
We plotted the normalized light-sensitive current over time and fitted the data with a single-exponential decay.
Gain of the excitatory currents was measured by integrating the current over time and dividing by the flash strength, and hence has units of nC/R*/rod/s.
10.7554/eLife.09685.018 Author response image 1. Example plot showing changes in the holding current over time for post-before-pre pairing protocol with Δt = −20 ms in control t-LTD (n = 9) and with DA added after pairing (n = 11).
The E C is calculated based on the ratio of total electrons recovered as I to maximum possible electrons recoverable if all substrate removal produces current; this is calculated using the following equation: (2) E C = C P C max × 100%%, where C P is the total coulombs calculated by integrating the current over time.
It is not clear though that it was the frequency of the pulsations and not current per se which was responsible for the memory improvement [42], as intermittent tDCS has been reported to have the same effects on neural excitability as constant tDCS [43], [44], particularly when total current over time is matched [45].
