Sentence examples for a positive onset from inspiring English sources

Compared with the control samples, the typical product exhibits the excellent catalytic activity in terms of not only a positive onset potential and high current density, but also low H2O2 yield and approximate four-electron reaction pathway in alkaline media.

The (Co@NPC-900 12 Co@NPC-900 12bits high ORR performancatalysta positivexhibitspotential of 1.050 V vs. Rhighnd a half-wave pORRntial of 0.824 V vs. RHE, which is comperformanceh the commercial 20% Pt/C.

As expected, the Fe-P/CNFs showed a high ORR electrocatalytic activity with a more positive onset potential of 1.01 V, similar with 1.03 V at 20 wt% Pt/C, and a good long-term stability (94% retention of current density after chronoamperometry 20,000s).

Cyclic voltammetry and rotating disk electrode results revealed that the ORR catalyzed by FeTSPc/SWCNTs presented a direct four-electron pathway with a very positive onset potential (+0.05 V vs Ag/AgCl, 3 M KCl), cathodic peak potential (−0.10 V vs Ag/AgCl, 3 M KCl) and a large kinetic rate constant (2.31 × 10−2 cm s−1).

The benchmark p-Si|Pt photocathode has a more positive onset potential than p-Si|TiNicat; a photocurrent onset potential of approximately 0.4 V with a current density of −9 mA cm−2 at 0 V vs. RHE was observed.

However, a highly positive onset potential exists due to the location of the conduction band (CB) of ZnO Ga at the high end.

The reason may be correlated with the fact that the relatively thick ZnO shell itself shows a more positive onset potential than the pristine In2S3 NSAs (Figs. S3c and S4a).

A more positive onset potential may be achieved by using different strategies, for example, by using very thin insulating layers between TiNicat and p-Si to electrically decouple those two layers.[ 12] Photocathodes fabricated with TiNicat also exhibit good stability with a negligible decrease in the photocurrent after 4 h of continuous solar light irradiation.

Based on the unique hybrid structure, PtCu@GQDs capsules showed remarkably enhanced catalytic activity for oxygen reduction reaction (ORR) with a 2 times higher mass activity and a 40 mV more positive onset potential than that of commercial Pt black, indicating the promise of the newly-prepared PtCu@GQDs capsules as catalysts for fuel cell applications.

Negative onset time (gap condition) resulted in a shorter mean latency, while positive onset time (overlap condition) resulted in a longer mean latency.

The dopamine@CNT hybrid (denoted as DA@CNT) reveals an enhanced electrocatalytic activity towards ORR with highly positive onset potential and cathodic current as a result of their outstanding features of longitudinal mesoporous structure, high surface area, and ornamentation of DA layers with nitrogen moieties, which enable fast electron transport and fully exposed electroactive sites.
