Half‐Century Ammonia Emissions From Agricultural Systems in Southern Asia: Magnitude, Spatiotemporal Patterns, and Implications for Human Health

GeoHealth, 2018
Much concern has been raised about the increasing threat to air quality and human health due to ammonia (NH3) emissions from agricultural systems, which is associated with the enrichment of reactive nitrogen (N) in southern Asia (SA), home of more than ...

Lewis Acid Site Engineering in MOF‐Derived Aluminum Oxide/Carbon Composites for Dechlorination of Waste Plastic Pyrolysis Oil

Advanced Functional Materials, EarlyView.
Controlled carbonization of an Al‐MOF partially decomposes its linkers, exposing coordinatively unsaturated Al centers within an oxide/carbon composite. The resulting Lewis acid sites, rather than surface area, govern organochlorine capture: the composite removes chemically diverse organochlorines from waste plastic pyrolysis oil, outperforms a ...

Subsurface banding increases ammonia emissions under rainfed cotton in Florida sandy soils

Frontiers in Agronomy
Ammonia (NH3) volatilization is a significant pathway for nitrogen (N) loss. The acidic, sandy soils of Florida offer ideal conditions for NH3 losses in rainfed cotton production systems.

Nitrogen: from discovery, plant assimilation, sustainable usage to current enhanced efficiency fertilizers technologies – A review [PDF]

Revista Brasileira de Ciência do Solo
From 1913 onwards, the global situation changed from a scenario of nitrogen (N) scarcity to an abundance of ammonia (NH3) produced synthetically via the Haber-Bosch process.

Zwitterionic Polymer Coating Enabled Chronic Dopamine Sensing and Electrophysiology Recording in Free‐Moving Mice

Advanced Healthcare Materials, EarlyView.
Application of a zwitterionic poly(sulfobetaine methacrylate) (PSB) coating to microelectrode arrays and Ag/AgCl reference electrodes effectively inhibits biofouling and structural degradation. This strategy successfully enables simultaneous, long‐term electrophysiological recording and dopamine sensing in freely behaving mice, facilitating ...

An experimental study on the characteristics of ammonia/coal mild gasification-combustion and the Fuel-N transformation

Meitan xuebao
Ammonia (NH3) is a carbon-free and hydrogen-rich fuel. NH3 co-firing in coal-fired boiler is an effective approach to reduce carbon emissions from the combustion source.

National-scale nitrogen stoichiometry in China’s surface waters: spatiotemporal dynamics, proxy utility, and threshold-driven controls

npj Clean Water
Ammonia nitrogen (NH3-N) and total nitrogen (TN) are key components of freshwater nitrogen cycling, yet national-scale assessments of NH3-N/TN ratios, their seasonal variability, and environmental controls remain limited.
