A loss of ozone around 40 km is particularly significant because that is the altitude where chlorine is thought to be the major player in the destruction of ozone.

II-VI short wavelength lasers have had to overcome several technical challenges to become what they are today. Arguably the foremost obstacle to practical ZnSe based light emitters was the ability to p-type dope the semiconductor. It was discovered that by incorporating free nitrogen radicals in ZnSe sufficiently high p-type doping could be obtained. 6, record 1, English, - nitrogen%28%26%23183%3B%29

The injection of natural gas and urea has been shown to enhance the NOx reduction potential of the natural gas in utility boilers. The chemical kinetics mechanisms of FLGR® and SNCR have many of the same selective reactions. The injection of natural gas in hot, low oxygen furnace gas results in the formation of hydrocarbon radicals (CHi) and the subsequent formation of nitrogen radicals. The injection of urea (NH2-CO-NH2) results in the formation of similar nitrogen radicals. Both of these reagents reduce NOx to molecular nitrogen through a series of similar reactions. 8, record 1, English, - nitrogen%28%26%23183%3B%29

New studies of the catalytic destruction of ozone in the lower stratosphere suggest a reordering of the catalytic cycles. Recent in-situ observations (from ER-2 flights) suggest that nitrogen radicals may not be as dominant in the catalytic destruction of ozone in the lower stratosphere as previously thought. 9, record 1, English, - nitrogen%28%26%23183%3B%29

The nitrogen monoxide radical. This peculiar radical derived from nitrogen (NO·) is produced by endothelial cells and plays a prime physiological role in the regulation of blood pressure. Oxidative stress can lead to dysfunctioning of endothelial cells, causing them to produce the nitrogen monoxide radical in excess. The radical may then react with oxygenated free radicals to form substances that are highly toxic to the organism: peroxynitric derivatives (HOONOH). 8, record 4, English, - oxidonitrogen%28%26%23183%3B%29
