Structure-activity relationships to estimate the effective Henry's law constants of organics of atmospheric interest
Structure-activity relationships the effective Henry's law atmospheric interest
2010/8/25
The Henry's law constant is a key property needed to address the multiphase behaviour of organics in the atmosphere. Methods that can reliably predict the values for the vast number of organic compoun...

marine organics the air quality the western United States
2010/8/16
The contribution of marine organic emissions to the air quality in coastal areas of the western United States is studied using the latest version of the US Environmental Protection Agency (EPA) region...
Design and construction of a simple Knudsen Effusion Mass Spectrometer (KEMS) system for vapour pressure measurements of low volatility organics
Design construction Knudsen Effusion Mass Spectrometer (KEMS) system vapour pressure measurements
2010/2/8
A design of and initial results from a Knudsen Effusion Mass Spectrometer (KEMS) are presented. The design was adapted from high temperature alloy studies with a view to using it to measure vapour pre...
Hygroscopic properties of water-soluble matter and humic-like organics in atmospheric fine aerosol
Hygroscopic properties water-soluble matter humic-like organics atmospheric fine aerosol
2009/2/20
Ambient continental-rural fine aerosol (K-puszta, Hungary, PM1.5) was sampled on quartz fibre filters in winter and summer 2001. Water-soluble matter (WSM) was extracted in MilliQ-water, and, in a sec...
Cloud droplet activation and surface tension of mixtures of slightly soluble organics and inorganic salt
Cloud droplet activation slightly soluble organics inorganic salt
2009/2/6
Critical supersaturations for internally mixed particles of adipic acid, succinic acid and sodium chloride were determined experimentally for dry particles sizes in the range 40-130nm. Surface tension...
Organics in the Northeastern Pacific and their impacts on aerosol hygroscopicity in the subsaturated and supersaturated regimes
Organics in the Northeastern Pacific aerosol hygroscopicity supersaturated regimes
2009/1/15
Aerosol samples were collected by aircraft during the summer of 2004 in the Northeastern Pacific and compared to measurements of aerosol hygroscopicity. Chemical speciation analyses of the samples rev...
