Organic acids as cloud condensation nuclei：Laboratory studies of highly soluble and insoluble species
Organic acids cloud condensation nuclei soluble and insoluble species
2009/3/10
The ability of sub-micron-sized organic acid particles to act as cloud condensation nuclei (CCN) has been examined at room temperature using a newly constructed continuous-flow, thermal-gradient diffu...
Optical properties in the UV and visible spectral region of organic acids relevant to tropospheric aerosols
Optical properties UV organic acids tropospheric aerosols
2009/3/5
Refractive and absorption indices in the UV and visible region of selected aqueous organic acids relevant to tropospheric aerosols are reported. The acids investigated are the aliphatic dicarboxylic a...
Low molecular weight organic acids in aerosol particles from Rondônia, Brazil, during the biomass-burning, transition and wet periods
Low molecular weight organic acids aerosol particles Brazil
2009/2/7
Particles from biomass burning and regional haze were sampled in Rondônia, Brazil, during dry, transition and wet periods from September to November 2002, as part of the LBA-SMOCC (Large-Scale B...
Modelling the cloud condensation nucleus activity of organic acids on the basis of surface tension and osmolality measurements
cloud condensation nucleus organic acids surface tension osmolality measurements
2008/12/18
In this study vapour pressure osmometry was used to determine water activity in the solutions of organic acids. The surface tension of the solutions was also monitored in parallel and then Köhler...
Heterogeneous uptake of the C1 to C4 organic acids on a swelling clay mineral
C. D. Hatch R. V. Gough M. A. Tolbert
2008/12/17
Mineral aerosol is of interest due to its physiochemical impacts on the Earth's atmosphere. However, adsorbed organics could influence the chemical and physical properties of atmospheric mineral part...
A fate for organic acids, formaldehyde and methanol in cloud water: their biotransformation by micro-organisms
organic acids formaldehyde cloud water biotransformation micro-organisms
2008/12/16
The interactions between microbial and chemical contents of cloud water were investigated. First, we observe that the bulk cloud water solution provides a substantial environment where bacteria can de...
