The use of nitrogen dioxide for the oxidation of ammonium nitrate
… of destroying ammonium nitrate by reduction with nitrogen dioxide (NO2). The use of NO2 as a reductant was first described in 1985, however, no further investigation or optimisation of the technique has been published since that time. The results of investigations into six key aspects of this …

Electron Spin Resonance Studies of the Addition of Nitrogen Dioxide to Alkenes
The addition of solutions of nitrogen dioxide to alkenes has been studied under various reaction conditions. Solutions of low concentration of nitrogen dioxide react with alkyl-substituted alkenes to produce dialkyl nitroxides, and react with a, β-unsaturated carbonyl compounds to produce iminoxy …

The response of 12 clones of eastern white pine (Pinus strobus L.) to ozone and nitrogen dioxide
Grafts were made using 2-0 rootstock and scion from 12 ortets of eastern white pine (Pinus strobus L.) growing at the Radford Army Ammunition Plant (RAAP). The 12 ortets represented 4 symptom severity classes (3 ortets/class) ranging from trees with > 25% of their crowns exhibiting necrotic tipburn …

Interfacial Reaction of an Olefin-Terminated Self-Assembled Monolayer Exposed to Nitrogen Dioxide: An Investigation Into the Reaction Rate and Mechanism
… strongly oxidizing pollutants, such as ozone and nitrogen dioxide, with alkenes in the gas and solution phases are well known, the interfacial reaction mechanisms of these species is not fully understood. The goal of this study is to determine the reaction mechanism when an unsaturated hydrocarbon …

Ground- and satellite-based observations of column nitrogen dioxide: instrument performance, column-to-surface relationships, and the role of meteorology in coastal urban environments
Nitrogen dioxide (NO2) is a criteria air pollutant that is deleterious to human health and the environment, but characterizing its distribution is challenging. This challenge arises from its abundant and heterogeneous sources, short lifetime, and the limited spatial extent of surface monitoring …

Investigation of the Photoenhanced Reduction of Nitrogen Dioxide (NO2) on Organic Films and Above Soils as the Missing Source of Daytime Tropospheric Nitrous Acid (HONO)
Recent observed unpredictably high HONO daytime concentrations, demanding its ordinarily proposed heterogeneous source to proceed > 60 times faster at noon than during the night, prompted this study, concerning the effect of UV-A radiation on the uptake kinetics of gas-phase NO2 on various …

Heterogeneous chemistry of HONO and surface exchange
… to date are heterogeneous reactions with nitrogen dioxide as the HONO precursor or microbiological activity in soil. As the ground surface is a major source of HONO, the vertical distribution of HONO is very sensitive to the extent of vertical mixing. Additionally, some uncertainty in …
