A photochemistry study on nitrous oxide making use of site-selective excitation of terminal nitrogen, central nitrogen, and oxygen 1s-->3pi excitations is presented. The resonant Auger decay which takes place following excitation can lead to dissociation of the N2O+ ion. To elucidate the nuclear dynamics, energy-resolved Auger electrons were detected in coincidence with the ionic dissociation p...

Composting is the major technology in the treatment of animal manure and is a source of nitrous oxide, a greenhouse gas. Although the microbiological processes of both nitrification and denitrification are involved in composting, the key players in these pathways have not been well identified. Recent molecular microbiological methodologies have revealed the presence of dominant Bacillus species...

The microbial processes of denitrification and dissimilatory nitrate reduction to ammonium (DNRA) are two important nitrate reducing mechanisms in soil, which are responsible for the loss of nitrate ([Formula: see text]) and production of the potent greenhouse gas, nitrous oxide (N(2)O). A number of factors are known to control these processes, including O(2) concentrations and moisture content...

1 ABSTRACT Atmospheric deposition is important to nutrient loadings to coastal estuaries. Atmospheric emissions of nitrogen travel hundreds of kilometers as they are removed via atmospheric deposition. Long-range transport from outside the Neuse/Pamlico system in North Carolina is an important contributor to the total (wet + dry) deposition of nitrogen to the watershed, estuary and Sound. We ne...

A new route has been developed to synthesize nitrogen-doped reduced graphene oxide (N-RGO) with excellent lithium storage properties. Nitrogen-doped graphene oxide (N-GO) is firstly synthesized and then reduced to N-RGO. The nitrogen content of N-GO can reach up to 5.6 wt%. After hydrothermal treatment, the nitrogen content of N-RGO still remains at 2.0 wt%. Our N-RGO material reveals excellent...

Starting from the colored oxynitride LaTiO2N, new perovskite-type solid solutions have been evidenced in the systems La1-xAxTiO2+xN1-x (A = Sr, Ba) by ammonolysis at 950°C of corresponding oxide precursors prepared by molten salt route. The color of the resulting powders varies progressively from the brown of LaTiO2N to the white of the oxide with the decrease of both nitrogen and lanthanum con...

3-nitrotyrosine formation is an oxidative protein modification that was first discovered in vivo in the early 1990s by Beckman and colleagues.1,2 The biological relevance of this process was extensively investigated in the subsequent years and further facilitated by the development of 3-nitrotyrosine– specific antibodies.3 Protein tyrosine nitration is mainly mediated by 3 biochemical processes...

Endogenous formation of nitric oxide (NO) and related nitrogen oxides in the vascular system is critical to regulation of multiple physiological functions. An imbalance in the production or availability of these species can result in progression of disease. Nitrogen oxide research in the cardiovascular system has primarily focused on the effects of NO and higher oxidation products. However, nit...

This work reports the study concerning the influence of the preparation conditions on the structure of silicon rich oxide (SRO) deposited by PECVD method by which the structural properties of the film are strictly related. In particular we investigated the role of reactant gases N2O and SiH4 on the total Si concentration, Si excess concentration, Si clustered concentration and size of nanoclust...
