Values of global current efficiencies greater than 20% were obtained even operating with low reactant concentration (0.17 mM for diuron and 2 mM for dichloroaniline) provided that a suitable ratio between applied current and mass transfer rate was guaranteed.
Using a platinised titanium anode it is shown that current efficiencies (greater than 70%) can be achieved provided the concentration of glyoxylic acid does not exceed approximately 5 g dm−3.
Potential-dependent results revealed that the modified electrode exhibited an earlier onset potential, higher Faradaic efficiency and greater current density for CO evolution when compared to its smooth-surface counterpart.
By employing an auxiliary amplifier cross-coupled to the gate of bulk-driven flipped voltage follower and input differential pairs, it achieves not only the gain-bandwidth improved, but also the slew rate significantly enhanced, which leads to a great boost in current efficiency.
At only 10 V, the luminance approaches 50,000 cd/m2 with an external quantum efficiency over 2% and a current efficiency greater than 21 cd/A.
Based on the experimental results, namely the electrode impedance and emission efficiency, it was calculated that ferrous species were leaving the electrode surface with a current efficiency greater than unity at intermediate frequencies.
Great enhancements at high current efficiency and output power via wafer bonding technology and LLO have been shown [16 18].
The process can be operated at a superficial current density greater than 1500 A m−2, with an average selectivity greater than 80%, and a current efficiency > 75% for p-aminophenol in the experimental packed electrode reactor.
OLEDs with bis(salicylidene-p-methylaniline zinc II) (Zn(salicylidene-p-methylaniline zinc IIyer exhibited high current efficiency, indicating itsalicylidene-p-methylaniline zinc IIon transport material for OLEDs.
The increase in j always enhanced the decolorization and mineralization processes because of the greater production of hydroxyl radicals, but decreases the mineralization current efficiency.
