Triple-conducting materials have been proved to improve the performance of popular protonic ceramic electrolysis cells. However, partially because of the complexity of the water-splitting reaction involving three charge carriers, that is, oxygen (O), proton (H), and electron (e), the triple-conducting reaction mechanism was not clear, and the reaction conducting pathways have seldom been addressed. In this study, the triple-conducting Ruddlesden-Popper phase PrBaNiO as an anode on the BaCeZrYYbO electrolyte was fabricated and its electroresponses were characterized by electrochemical impedance spectroscopy with various atmospheres and temperatures.

Although numerous studies have reported the associations between PM and stroke, scientific evidence in China is incomplete, particularly the effect of PM on the acute incidence and national acute health burdens of stroke attributed to PM pollution. This study identified about 131,947 registered patients and 23,018 deaths due to stroke in 10 counties located in various regions from 2013 to 2017.
