Unlike a majority of the multidimensional models that predict the current density to be higher either under the flow-channel area or under the land region, our model illustrates that the location of higher current (electrode reaction rate) changes from the region under the flow channel to that under the land area depending on the overpotential.
Only one of the 13 genes with increased expression on the high-current electrode had substantial changes between the KN400 and the PCA strain.
Electrochemical properties of as-synthesized NiO NWAs were evaluated by cyclic voltammetry and galvanostatic charge/discharge; porous NiO NWAs electrode delivered a specific capacitance of 270 F/g (0.67 A/g); even at high current densities, the electrode could still deliver a high capacitance up to 236 F/g (13.35 A/g).
Intense plasma jets are achieved through a high current and high electrode negative (EN) ratio based pulsed AC-GMAW, which has high negative peak currents in the EN region of the pulse.
At high current densities, both electrodes showed comparable reversible capacities, demonstrating the suitability of the present synthetic technique.
Also, under certain conditions, and at sufficiently high current densities, the working electrode is covered entirely by a very large bubble, producing a blanketing effect similar to the anode effect in aluminum production.
After forming the heterogeneous structure, the graphene coating in the NPL plays an important role in enhancing the electrical conductivity, which reduces the electrode polarization during discharge/charge at high current densities and makes the nanoporous electrode show more capacitive than diffusion-controlled behavior.
In acid medium only platinum electrodes are electroactive, whereas in alkaline medium both electrodes, particularly gold electrodes, give relatively high current densities (about 20 mA cm−2 for 0.1 M glycerol at 25°C).
The reaction is controlled by the diffusion of CO2 through the metal layer of the SPE electrode at high current density.
The high electrocatalytic properties of N-GF afford 4 6% greater voltage and energy efficiencies in VRFB than the conventional O-GF electrode at high current density (110 mA cm−2) with ∼38% higher initial charge-discharge capability owing to the significantly reduced overpotential.
In presence of NAD+, the resulting enzyme electrode exhibits high current densities for glucose oxidation with a detection limit of 1 μM glucose.
