From:Atmospheric Chemistry and Physics (Vol. 20, Issue 1) Peer-ReviewedMultifunctional organic nitrates, including carbonyl nitrates, are important species formed in NO.sub.x -rich atmospheres by the degradation of volatile organic compounds (VOCs). These compounds have been shown to play a...
-
From:Advances in Materials Science and EngineeringPeer-ReviewedStrong ultraviolet light and low-temperature are the typical environmental characteristics in high-altitude areas. The performance of SBS-modified asphalt in the above environmental characteristics needs further study....

From:Atmospheric Chemistry and Physics (Vol. 16, Issue 3) Peer-ReviewedThe Mediterranean basin is characterized by large concentrations of aerosols from both natural and anthropogenic sources. These aerosols affect tropospheric photochemistry by modulating the photolytic rates. Three...
-
From:Atmospheric Measurement Techniques (Vol. 9, Issue 1) Peer-ReviewedFormaldehyde (CH.sub.2 O) is the most abundant aldehyde in the atmosphere, and it strongly affects photochemistry through its photolysis. We describe simultaneous measurements of CH.sub.2 O and nitrogen dioxide...
-
From:Atmospheric Chemistry and Physics (Vol. 15, Issue 4) Peer-ReviewedUncertain photolysis rates and emission inventory impair the accuracy of state-level ozone (O.sub.3) regulatory modeling. Past studies have separately used satellite-observed clouds to correct the model-predicted...
-
From:PLoS ONE (Vol. 11, Issue 10) Peer-ReviewedNcm, 6-nitrocoumarin-7-ylmethyl, is a photolabile protective group useful for making "caged" molecules. Ncm marries the reliable photochemistry of 2-nitrobenzyl systems with the excellent stability and spectroscopic...

From:Atmospheric Chemistry and Physics (Vol. 18, Issue 15) Peer-Reviewed
Recent field studies have suggested that sea-salt particulate nitrate (NITs) photolysis may act as a significant local source of nitrogen oxides (NO.sub.x) over oceans. We present a study of the global impact of this...
