In a form of thin-layer electrode on glassy carbon support, in 0.1 M KOH solution, the prepared materials displayed high activity toward oxygen reduction reaction (ORR) in alkaline media, with onset potentials more positive than −0.10 V vs. SCE.
Catalysts grown in phosphorus-containing media showed improved onset of activity, increased current density and higher selectivity for water formation.
Regrettably, scientific discrepancies were divulged to and reported by the media after the onset of the submarine eruption (October-November, 2011).
The CoO@N/S-CNF not only exhibits highly efficient catalytic activity towards oxygen reduction reaction (ORR) in alkaline media with an onset potential of about 0.84 V, but also shows better stability and stronger resistance to methanol than Pt/C.
Sites like BuzzFeed have mastered the platform-specific approach to media, and the onset of brand journalism has completely changed what it takes for us to "trust" a source.
Cells co-expressing Hsp104-mCherry and AID-GFP were switched to auxin-containing media at the onset of imaging, and the GFP intensities were measured over time from neighboring cells containing or not an Hsp104-puncta.
Fig. 8 Change in pH (a), total P concentration (b), acid- (c) and alkaline phosphatase activity (d) in the liquid fraction of media 65 h after onset of incubation.
Effective ORR electrocatalysis by OMC in alkaline media was evidenced, with onset potential amounting to −0.10 V vs. saturated calomel electrode.
The nanostructured Ag MnO2 catalysts exhibit improved oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) performance in aqueous alkaline media, in terms of onset potential, generated current density and Tafel slopes.
By utilizing digital volunteers and crowdsourcing the seemingly mundane task of looking through images and social media posts at the onset of a crisis can expedite response organizations' assessments and allow them to be even quicker in rescue and response.
