Air Pollution in Europe

open access: yesChemSusChem, 2018
AbstractIn this short critical perspective, we outline the serious problems caused by air pollution in Europe. Using two types of metrics, level assessment and trend assessment, we quantify the contribution of ammonia, NOx, SOx, non‐methane volatile organic compounds, and particulate matter in terms of years of life lost per capita and explain the ...

Synergistic Effects of Ruthenium and Zinc Active Sites Fine Tune the Electronic Structures of Augmented Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
This study presents an electronic fine‐tuning (EFT) strategy to optimize the electronic structures of Ru species and single‐atom Zn sites by the virtue of layered nanosheets, significantly enhancing ORR and HER activities. Spectroscopic analysis and theoretical calculations uncover that this EFT effect breaks the ORR scaling limitation and positions ...
