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

Surface nitrous oxide concentrations and fluxes from water bodies of the agricultural watershed in Eastern China.
TL;DR: Results showed that surface-dissolved N2O concentration in water bodies of the agricultural watershed in Eastern China, one of the most intensive agricultural regions, was measured over a two-year period, highlighting the potential constraints in the IPCC methodology for water with a high anthropogenic N input.

Comparisons of biological nitrogen fixation in association with white clover (Trifolium repens L.) under four fertiliser nitrogen inputs as measured using two 15N techniques
W. Burchill,Euan K. James,Dejun Li,Gary Lanigan,Michael Williams,Pietro P. M. Iannetta,James Humphreys +6 more
TL;DR: The two 15N techniques were comparable in estimating BNF, achieving a balance between minimising detrimental impact on BNF and potential N loss while producing more herbage DM yield than clover swards receiving no fertiliser N.

N2O production by ammonia oxidizing bacteria in an enriched nitrifying sludge linearly depends on inorganic carbon concentration.
TL;DR: The observation in this study indicates that alkalinity (mostly contributed by IC) could be a significant factor influencing N2O production and should be taken into consideration in estimating and mitigating N 2O emissions in wastewater treatment systems.

Habitat partitioning of marine benthic denitrifier communities in response to oxygen availability
TL;DR: Quantification of the genetic potential for denitrification, anammox and respiratory ammonification indicated thatdenitrification supported nitrogen removal in coastal marine surface sediments, and denitrifiers with a complete pathway were identified as the dominant community involved in N2 O reduction, rather than organisms that are only N1 O reducers.

Oxidation of cyclohexane to adipic acid catalyzed by Mn-doped titanosilicate with hollow structure
Guoqiang Zou,Wenzhou Zhong,Qiong Xu,Jiafu Xiao,Chang Liu,Yongqiang Li,Liqiu Mao,Steven R. Kirk,Dulin Yin +8 more
TL;DR: One-step oxidation of cyclohexane to adipic acid (AA) was carried out at 413 K over manganese-doped titanium silicalite with hollow structure (HTS) using oxygen as oxidant without any initiator or solvent as discussed by the authors.

TL;DR: The first volume of the IPCC's Fourth Assessment Report as mentioned in this paper was published in 2007 and covers several topics including the extensive range of observations now available for the atmosphere and surface, changes in sea level, assesses the paleoclimatic perspective, climate change causes both natural and anthropogenic, and climate models for projections of global climate.

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.
