WASHINGTON US President Donald Trump on Tuesday said possible talks between North Korea and South Korea held mixed potential, while sanctions were beginning to take a toll on Pyongyang amid tensions over its nuclear and missile programmes."Sanctions and 'other' pressures are beginning to have a big impact on North Korea.
The sample PC acts to suppress the cathodic activity of the rivet and the couple behaves largely as that of the Mg alloy, as can be observed from the mixed potential value which is similar to the OCP of pure AM60B (Figure 14b and c).
The experiment in the zero resistance ammeter (ZRA) mode ensures that the two working electrodes (WE-1 and WE-2) behave as if they were directly connected by a 'zero-resistance' wire, such that the galvanic current between cathode and anode, and the mixed potential between them can be measured/recorded.
This decreasing trend in cell performance at higher ethanol concentrations can be explained as resulting from (a) creation of mixed potential at the cathode due to fuel crossover; (b) kinetic decrease in anode; (c) transport resistance increase at the anode; and (d) ohmic resistance increase.
In a fluidic system, fuel crossover can create mixed potentials, decrease in cell efficiency, and could even deactivate the catalyst.
The redox potential (mixed potential) at the working electrode was measured throughout the reduction reaction using a potentiostat.
Among the several classifications of electrochemical gas sensors, mixed potential based devices have gained prominence in gas sensing applications.
The spatial domain MoM, based on the spatial-domain mixed potential Green's functions (MPGFs), are of great interest in the analysis of cylindrical microstrip antennas (Fig.
Anodic and cathodic processes are coupled and take place at the same speed and at a common potential, called mixed potential (Badea, 2000).

This is the case required when using the Method of Moments (MoM) [17] with low order basis functions to discretize the Mixed Potential Integral Equations (MPIE) [18], or when SIE-MoM strategies are utilized to tackle static problems [16].
