UNIVERSITY PARK, Pa. -- Developing the cloak of invisibility would be wonderful, but sometimes simply making an object appear to be something else will do the trick, according to Penn State electrical...
Measurements of Gaseous NH3 and Particulate NH4 + in the Atmosphere by Fluorescent Detection after Continuous Air–water Droplet Sampling
Ammonia Gas-particle partitioning Microflow analysis Short-term variation
2016/3/28
Phase partitioning of NHx (gaseous NH3 and particulate NH4
+) in the atmosphere is crucial for the lifetime of NHx
during atmospheric transport. Reliable data for gaseous NH3 and NH4
+ in aerosols ...
