Ultrafast Vertical Organic Electrochemical Transistors With Ion‐Permeable Conductive Polymer Top Electrodes

open access: yesAdvanced Materials, EarlyView.
Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

Effects of Transformers' Short-circuit Voltages and Short-circuit Powers of the Grid Equivalent on Short-circuit Current.

open access: yes, 2017
In power systems, the most dangerous condition in the electromagnetic transients is the short circuit. When short circuit occurs, circuit impedance falls, the current increases and the voltage drops. These changes cause dangerous consequences to the grid.
