TLDR
In this paper, the ozone depletion potential-weighted anthropogenic emissions of N2O with those of other ozone-depleting substances were compared, and it was shown that N 2O emission currently is the single most important ozone-destroying emission and is expected to remain the largest throughout the 21st century.Abstract:
By comparing the ozone depletion potential-weighted anthropogenic emissions of N2O with those of other ozone-depleting substances, we show that N2O emission currently is the single most important ozone-depleting emission and is expected to remain the largest throughout the 21st century. N2O is unregulated by the Montreal Protocol. Limiting future N2O emissions would enhance the recovery of the ozone layer from its depleted state and would also reduce the anthropogenic forcing of the climate system, representing a win-win for both ozone and climate.read more

Powering denitrification: the perspectives of electrocatalytic nitrate reduction
TL;DR: The electrocatalytic removal of polluted water is a promising alternative to bacterial denitrification, provided that full selectivity to harmless N2, which can be returned to the atmosphere, is achieved as mentioned in this paper.

On the systematic design and selection of optimal working fluids for Organic Rankine Cycles
TL;DR: In this paper, the authors present an approach to the systematic design and selection of optimal working fluids for organic Rankine cycles (ORCs) based on computer aided molecular design (CAMD) and process optimization techniques.

N2O emissions from activated sludge processes, 2008-2009: results of a national monitoring survey in the United States.
TL;DR: It can be argued that activated sludge processes that minimize transient or permanent build up of ammonium or nitrite, especially in the presence of dissolved oxygen, are expected to have low N(2)O emissions.

Recently identified microbial guild mediates soil N2O sink capacity
Christopher M. Jones,Christopher M. Jones,Aymé Spor,Fiona Brennan,Fiona Brennan,Fiona Brennan,Marie-Christine Breuil,David Bru,Philippe Lemanceau,Bryan S. Griffiths,Bryan S. Griffiths,Sara Hallin,Laurent Philippot +12 more
TL;DR: In this article, the capacity of soils to take up Nitrous Oxide (N2O) is mostly explained by the abundance and diversity of a newly described N2O-reducing microbial group.

Abundance of microbial genes associated with nitrogen cycling as indices of biogeochemical process rates across a vegetation gradient in Alaska
Dorthe Groth Petersen,Steven J. Blazewicz,Mary K. Firestone,Donald J. Herman,Merritt R. Turetsky,Mark P. Waldrop +5 more
TL;DR: Functional gene abundance is a valuable index that integrates recent environmental history and recent process activity, and therefore is a good predictor of potential rates of nitrification and denitrification across terrestrial ecosystems.

The influence of nitrogen oxides on the atmospheric ozone content
TL;DR: In this paper, the probable importance of NO and NO2 in controlling the ozone concentrations and production rates in the stratosphere is pointed out and some processes which may lead to production of nitric acid are discussed.
