Ultralow overpotential nitrate reduction to ammonia via a three-step relay mechanism

open access: yesNature Catalysis, 2023
Ammonia plays a substantial role in agriculture and the next generation of carbon-free energy supply. Electrocatalytic nitrate reduction to NH_3 is attractive for nitrate removal and NH_3 production under ambient conditions.

Coupling nitrate capture with ammonia production through bifunctional redox-electrodes

open access: yesNature Communications, 2023
Coupling nitrate capture with conversion to ammonium is attractive because it combines pollutant remediation and chemical production. Here, the authors design a bifunctional redox-electrode to achieve the reactive separation of nitrate to ammonium in a ...

Active hydrogen boosts electrochemical nitrate reduction to ammonia

open access: yesNature Communications, 2022
Electrochemical nitrate reduction to ammonia is a promising alternative strategy to the traditional Haber-Bosch process but suffers from a low Faradaic efficiency and limited ammonia yield due to the sluggish multi-electron/proton-involved steps. Herein,

Electrochemical ammonia synthesis via nitrate reduction on Fe single atom catalyst

open access: yesNature Communications, 2021
Electrochemically converting nitrate, a widespread water pollutant, back to valuable ammonia is a green and delocalized route for ammonia synthesis, and can be an appealing and supplementary alternative to the Haber-Bosch process.

Nitrate and periplasmic nitrate reductases [PDF]

open access: yesChem. Soc. Rev., 2014
The nitrate anion is a simple, abundant and relatively stable species, yet plays a significant role in global cycling of nitrogen, global climate change, and human health. Although it has been known for quite some time that nitrate is an important species environmentally, recent studies have identified potential medical applications.

Nitrates for achalasia [PDF]

open access: yesCochrane Database of Systematic Reviews, 2002
Achalasia is a disease that impairs oesophageal motility. Though nitrates have been used to treat achalasia for a long time, the effectiveness of nitrates for achalasia is still controversial.To quantify short-term and long-term effects of nitrate therapy in patients with achalasia.Trials were identified by searching the Cochrane Controlled Trials ...

Nitrogen-­containing substances in the snow of the fall areas of the Proton launch vehicle stages in 2009–2019

open access: yesЛëд и снег, 2021
The article presents analysis of the snow pollution caused by flights of the Proton launch vehicles launched from the Baikonur cosmodrome in 2009–2019. Data on 1477 snow samples collected in areas in Central Kazakhstan, south­east of Western Siberia, and ...

NIN-like protein 7 transcription factor is a plant nitrate sensor

open access: yesScience, 2022
Nitrate is an essential nutrient and signaling molecule for plant growth. Plants sense intracellular nitrate to adjust their metabolic and growth responses. Here we identify the primary nitrate sensor in plants.
