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

The acceleration of oceanic denitrification during deglacial warming
Eric D. Galbraith,Markus Kienast +1 more
TL;DR: The marine nitrogen cycle was altered during the transition from glacial to interglacial conditions as mentioned in this paper, and rates of denitrification in the water column accelerated during the last deglaciation.

TL;DR: In this article, the projected rise in agricultural nitrogen demands while achieving these 21st century ideals will require policies to coordinate solutions among technologies, consumer choice, and socioeconomic transformation, which will contribute lasting benefits for: (i) world hunger; (ii) soil, air and water quality; (iii) climate change mitigation; and (iv) biodiversity conservation.

Comparison between static chamber and tunable diode laser-based eddy covariance techniques for measuring nitrous oxide fluxes from a cotton field
Kai Wang,Kai Wang,Xunhua Zheng,Mari Pihlatie,Timo Vesala,Chunyan Liu,Sami Haapanala,Ivan Mammarella,Üllar Rannik,Huizhi Liu +9 more
TL;DR: In this article, the authors compared the N 2 O fluxes obtained from both static chamber and eddy covariance (EC) measurements for a year using the static chamber method based on a gas chromatograph (GC) and the EC technique based on tunable diode laser (TDL).

Enhancement of bacterial denitrification for nitrate removal in groundwater with electrical stimulation from microbial fuel cells
Baogang Zhang,Ye Liu,Shuang Tong,Maosheng Zheng,Yinxin Zhao,Caixing Tian,Hengyuan Liu,Chuanping Feng +7 more
TL;DR: In this article, electricity generated from the microbial fuel cell (MFC) is applied to the bioelectrical reactor (BER) directly as electrical stimulation means for enhancement of bacterial denitrification to remove nitrate effectively from groundwater.

TL;DR: Structural comparison of qNOR with cNOR and aerobic and microaerobic respiratory oxidases elucidates their evolutionary relationship and possible functional conversions and suggests that a water channel from the cytoplasm can serve as a proton transfer pathway for the catalytic reaction.
