“…Another mechanism for N 2 O formation of significance to soil acidophilic AOA is the formation of the nitrosonium cation (NO + ) from nitrous acid (HONO). Formation of NO + is favored at low pH (Ridd, ) and could contribute to abiotic hybrid N 2 O formation via electrophilic N‐nitrosation of NH 2 OH (Spott et al ., ). Although this reaction may be unfavorable in normal marine waters with near‐neutral pH, this may be an important source of N 2 O in some acidic soil environments with low pH (Martikainen and Deboer, ; Mørkved et al ., ) and could account for the reported two orders of magnitude higher N 2 O yield (N 2 O/

Recent studies point to the importance of oxygen (O ) in controlling the distribution and activity of marine ammonia-oxidizing archaea (AOA), one of the most abundant prokaryotes in the ocean. The AOA are associated with regions of low O tension in oceanic oxygen minimum zones (OMZs), and O availability is suggested to influence their production of the ozone-depleting greenhouse gas nitrous oxide (N O). We show that marine AOA available in pure culture sustain high ammonia oxidation activity at low μM O concentrations, characteristic of suboxic regions of OMZs (<10 µM O ), and that atmospheric concentrations of O may inhibit the growth of some environmental populations. We quantify the increasing N O production by marine AOA with decreasing O tensions, consistent with the plausibility of an AOA contribution to the accumulation of N O at the oxic-anoxic redox boundaries of OMZs. Variable sensitivity to peroxide also suggests that endogenous or exogenous reactive oxygen species are of importance in determining the environmental distribution of some populations.

“…NO reacts with alcohol to yield alky nitrites [144,145,146], which are also conveniently applied to alcohol determination in the aqueous solution [147,148] and biological samples [149]. The mechanism is that EtOH in vitro is nitrosated by NO or NO donors (e.g., N 2 O 3 and nitrosyl halides) to yield an O-nitroso compound or ethyl nitrite [150,151]. Interestingly when EtOH was perfused into rat gastric chamber system, luminal nitrite and nitrate levels decreased remarkably.…”

Ethanol (EtOH) in alcoholic beverages is consumed by a large number of individuals and its elimination is primarily by oxidation. The role of nitric oxide (NO) in EtOH's effects is important since NO is one of the most prominent biological factors in mammals. NO is constantly formed endogenously from L-arginine. Dose and length of EtOH exposure, and cell type are the main factors affecting EtOH effects on NO production. Either acute or chronic EtOH ingestion affects inducible NO synthase (iNOS) activity. However it seems that EtOH suppresses induced-NO production by inhibition of iNOS in different cells. On the other hand, it is clear that acute low doses of EtOH increase both the release of NO and endothelial NOS (eNOS) expression, and augment endothelium-mediated vasodilatation, whereas higher doses impair endothelial functions. EtOH selectively affects neuronal NOS (nNOS) activity in different brain cells, which may relate to various behavioral interactions. Therefore, there is an excellent chance for EtOH and NO to react with each other. Effects of EtOH on NO production and NOS activity may be important to EtOH modification of cell or organ function. Nitrosated compounds (alkyl nitrites) are often found as the interaction products, which might be one of the minor pathways of EtOH metabolism. NO also inhibits EtOH metabolizing enzymes. Furthermore, NO is involved in EtOH induced liver damage and has a role in fetal development during EtOH exposure in pregnancy. The mechanisms underlying these effects are only partially understood. Hence, the current discussion of the interaction of EtOH and NO is presented.

“…5 Again, nitrosonium ion (NO + ), an oxidized form of nitric oxide, is the key species in the process of nitrosation reactions, which most likely occur through electrophilic attack by NO/N 2 O 3 on a nucleophile center such as thiols/amines to generate S -nitrosothiols or N -nitrosamines. 6,7…”

Design of a Pyrene Scaffold Multifunctional Material: Real-Time Turn-On Chemosensor for Nitric Oxide, AIEE Behavior, and Detection of TNP Explosive

A dual-emission pyrene-based new fluorescent probe ( N -(4-nitro-phenyl)- N ′-pyren-1-ylmethyl-ene-ethane-1,2-diamine (PyDA-NP)) displays green fluorescence for nitric oxide (NO) sensing, whereas it exhibits blue emission in the aggregated state. The mechanism of nitric oxide (NO/NO + ) sensing is based on N-nitrosation of aromatic secondary amine, which was not interfered by reactive oxygen species and reactive nitrogen species. The aggregation-induced enhancement of emission (AIEE) behaviors of the PyDA-NP could be attributed to the restriction of intramolecular rotation and vibration, resulting in rigidity enhancement of the molecules. The AIEE behavior of the probe was well established from fluorescence, dynamic light scattering, scanning electron microscopy, transmission electron microscopy, X-ray diffraction, optical fluorescence microscopy, and time-resolved photoluminescence studies. In a H 2 O/CH 3 CN binary mixture (8:2 v/v), the probe showed maximum aggregation with extensive (833-fold) increases in fluorescence intensity and high quantum yield (0.79). The aggregated state of the probe was further applied for the detection of nitroexplosives. It displayed efficient sensing of 2,4,6-trinitrophenol (TNP), corroborating mainly the charge-transfer process from pyrene to a highly electron-deficient TNP moiety. Furthermore, for the on-site practical application of the proposed analytical system, a contact-mode analysis was performed.
