No laughing matter: Nitrous oxide rose at end of last ice age
No laughing matter Nitrous oxide end of last ice age
2014/12/30
CORVALLIS, Ore. – Nitrous oxide (N2O) is an important greenhouse gas that doesn’t receive as much notoriety as carbon dioxide or methane, but a new study confirms that atmospheric levels of N2O rose s...
Denitrification alternates between a source and sink of nitrous oxide in the hypolimnion of a thermally stratified reservoir
Denitrification alternates sink of nitrous oxide
2014/4/2
Nitrogen loading from developed watersheds to aquatic ecosystems can stimulate microbial denitrification, a
process that reduces nitrate (NO{
3
) to dinitrogen (N2) or nitrous oxide (N2O), the latt...
Control of nitrous oxide emission from Chironomus plumosus larvae by nitrate and temperature
nitrate temperature nitrous oxide emission
2014/4/16
Aquatic invertebrates that ingest large numbers of bacteria produce substantial amounts of the greenhouse gas
N2O because of incomplete denitrification in their anoxic gut. We investigated the influe...
Denitrification and nitrous oxide cycling within the upper oxycline of the eastern tropical South Pacific oxygen minimum zone
Denitrification nitrous oxide cycling
2014/4/17
One of the shallowest, most intense oxygen minimum zones (OMZs) is found in the eastern tropical South
Pacific, off northern Chile and southern Peru. It has a strong oxygen gradient (upper oxycline) ...
Tribological effects of oxide based nanoparticles in lubricating oils
nanoparticles surfactants lubricating oil tribological properties
2011/9/9
In order to enhance the tribological properties of lubricating oil, suitable surfactants such as Tween-20, Tween-60, Span-20 and Sodium sodecylbenzenesulfonate were selected and lubricating oils conta...
Potential role of copper availability in nitrous oxide accumulation in a temperate lake
copper nitrous oxide accumulation temperate lake
2014/4/22
Denitrifying bacteria require copper for the synthesis of nitrous oxide reductase. In the absence of sufficient bioavailable Cu, nitrous oxide (N2O) may accumulate in natural waters during denitrifica...
Sources of nitrogen used for denitrification and nitrous oxide formation in sediments of the hypernutrified Colne, the nutrified Humber, and the oligotrophic Conwy estuaries, United Kingdom
denitrifi cation nitrous oxide
2014/4/30
Rates of denitrification and nitrous oxide (N2
O) formation, and the sources of N2
and N2
O, were examined by
the isotope-pairing technique in three U.K. estuaries (Colne, Humber, Conwy), wh...
Kinetics of microbial Fe(III) oxide reduction in freshwater wetland sediments
Kinetics of microbial Fe(III) oxide reduction freshwater wetland sediments
2014/5/26
The kinetics of microbial amorphous Fe(III) oxide reduction was investigated in sediments from a freshwater wetland in north central Alabama, USA. Fe(III) oxide concentrations decreased exponentially ...
