If researchers could find a way to chemically convert carbon dioxide into fuels or other products, they might make a major dent in greenhouse gas emissions.
Observations of high rates of NO2-HONO conversion in the nocturnal atmospheric boundary layer in Kathmandu, Nepal
NO2-HONO conversion nocturnal atmospheric boundary layer Kathmandu Nepal
2009/9/11
Nitrous acid (HONO) plays a significant role in the atmosphere, especially in the polluted troposphere. Its photolysis after sunrise is an important source of hydroxyl free radicals (OH). Measurements...

Heterogeneous conversion of NO2 on secondary organic aerosol surfaces: A possible source of nitrous acid（HONO）in the atmosphere?
Heterogeneous conversion NO2 secondary organic aerosol nitrous acid HONO
2009/3/10
The heterogeneous conversion of NO2 on different secondary organic aerosols (SOA) was investigated with the focus on a possible formation of nitrous acid (HONO). In one set of experiments different or...
Atmospheric methanol measurement using selective catalytic methanol to formaldehyde conversion
Atmospheric methanol selective catalytic methanol formaldehyde conversion
2009/2/18
A novel atmospheric methanol measurement technique, employing selective gas-phase catalytic conversion of methanol to formaldehyde followed by detection of the formaldehyde product, has been developed...
Heterogeneous conversion of NO2 and NO on HNO3 treated soot surfaces: atmospheric implications
NO2 NO HNO3 soot surfaces atmospheric implications
2009/1/23
For the treatment of soot by pure HNO3 only reversible uptake with a surface coverage of ~1-2x1014 HNO3 cm-2 was observed for HNO3 mixing ratios in the range 250-800ppbv. Only for higher HNO3 mixing r...
