Prediction of short-range maximum NO2 concentrations using scalar PDFS

, 2004
Significant emissions of NOx (oxides of nitrogen: NO and NO2) are common from sources such as power stations, road tunnel ventilation outputs and freeways.

Impact of primary NO2 emissions at different urban sites exceeding the European NO2 standard limit [PDF]

, 2019
A large part of the European population is still exposed to ambient nitrogen dioxide (NO2) levels exceeding the European Union (EU) air quality standards, being a key challenge to reduce NO2 concentrations across many European urban areas, particularly

Integrating Machine Learning With Constant‐Potential Simulation to Unravel Charge‐Transfer Mechanisms in Electrochemical Nitrogen Fixation

Advanced Science, EarlyView.
Integrating interpretable machine learning with the fixed‐potential method reveals a novel mechanism: the catalytic activity of the electrochemical nitrogen reduction reaction is governed by partial charge transfer, induced by variations in the intermediate potential of zero charge under constant potential.

Tailored Catalytic Microenvironments Enable Efficient Electrochemical Ammonia Production

Advanced Science, EarlyView.
This study shows that Co2+ substitution in inverse spinel FeFeCoO4 constructs an integrated catalytic microenvironment for efficient nitrate‐to‐ammonia reduction. Jahn–Teller distortion activates Fe sites for *H generation, while hard–soft acid–base regulated dual‐metal sites optimize proton‐coupled electron transfer and intermediate adsorption ...

Bioinspired Interfacial Hydration Engineering via Metal–Organic Frameworks for Efficient Nitrate‐To‐Ammonia Conversion in Neutral Media

Advanced Science, EarlyView.
Inspired by Nitrite reductase, a metal–organic framework overlayer is introduced to regulate the interfacial hydration microenvironment on Cu electrodes, enriching hydrated K+ species that act as efficient proton donors. This strategy enables nitrate‐to‐ammonia conversion with near‐unity selectivity at industrial‐level current densities in neutral ...
