Establishing Performance Baselines for the Oxygen Evolution Reaction in Alkaline Electrolytes

Establishing Performance Baselines for Text Understanding Systems

A task-oriented evaluation of text understanding systems was prepared and conducted. Nine different NLP systems participated in the evaluation. NOSC collected 150 texts to be used as development (i.e. training) and test data and prepared explanatory documentation on them. The performance task--a simulated database update task--and the expected outputs for each text were defined. A scoring syste...

The value of establishing baselines.

the authors’ explanation is enlightening: there are more prescriptions written for narcotics but for a small number of patients from the general population. The database for Che and colleagues is a representative statewide sample of patients, rather than a list from a practice. Their study emphasizes the value of looking at total populations as a starting point, rather than simply our own pract...

Perovskite Electrocatalysts for the Oxygen Reduction Reaction in Alkaline Media

Oxygen reduction is considered a key reaction for electrochemical energy conversion but slow kinetics hamper application in fuel cells and metal-air batteries. In this review, the prospect of perovskite oxides for the oxygen reduction reaction (ORR) in alkaline media is reviewed with respect to fundamental insight into activity and possible mechanisms. For gaining these insights, special emphas...

Effect of Morphology of Co3O4 for Oxygen Evolution Reaction in Alkaline Water Electrolysis

In this paper, three different morphological Co3O4 electrodes for oxygen evolution reaction (OER) have been synthesized. By comparing the three morphologies of Co3O4, the electrocatalytic properties show that the urchin-like spheres of Co3O4 electrode has relative low overpotential and good electrocatalysis stability, indicating that the structure of urchin-like Co3O4 spheres exhibit an easy OE...
