Mapping environmental partitioning properties of nonpolar complex mixtures by use of GCxGC

Jeremy Samuel Arey, Jonas Gros, Petros Dimitriou Christidis, Deedar Nabi

Comprehensive two-dimensional gas chromatography (GC × GC) is effective for separating and quantifying nonpolar organic chemicals in complex mixtures. Here we present a model to estimate 11 environmental partitioning properties for nonpolar analytes based ...

Measurements of Submicron Aerosols at the California-Mexico Border during the Cal-Mex 2010 Field Campaign

Satoshi Takahama

We present measurements of submicron aerosols in Tijuana, Mexico during the Cal-Mex 2010 field campaign. A suite of aerosol instrumentations were deployed, including a hygroscopic-volatility tandem differential mobility analyzer (HV-TDMA), aerosol particle ...

Processing of biomass-burning aerosol in the eastern Mediterranean during summertime

Athanasios Nenes, Spyros Pandis

The aerosol chemical composition in air masses affected by wildfires from the Greek islands of Chios, Euboea and Andros, the Dalmatian Coast and Sicily, during late summer of 2012 was characterized at the remote background site of Finokalia, Crete. Air mas ...

Prediction Of Organic Aerosol Volatility And Unidentified Functional Group Concentrations From Fourier Transform Infrared (FTIR) Spectroscopy Measurements

Satoshi Takahama, Giulia Ruggeri, Sarah Elizabeth Shipley

Fourier Transform Infrared (FTIR) spectroscopy is used to measure the functional group composition of organic aerosols (Russell et al., 2011). However, certain functional groups are not directly detected by FTIR spectroscopy, either due to fundamental limi ...

Development of a MEMS Preconcentrator for Micro-gas Chromatography Analyses

Danick Briand, El Hadji Malick Camara

This paper presents the development of MEMS gas preconcentrator (GP) for the detection of trace level Volatile Organic Compounds (VOCs). Besides the development of the MEMS gas preconcentrator, we have also worked on the coupling of this preconcentration d ...

Suppression in droplet growth kinetics by the addition of organics to sulfate particles

Athanasios Nenes

Aerosol-cloud interactions are affected by the rate at which water vapor condenses onto particles during cloud droplet growth. Changes in droplet growth rates can impact cloud droplet number and size distribution. The current study investigated droplet gro ...

Isotope Effects as New Proxies for Organic Pollutant Transformation

Stephanie Spahr

Assessing the pathways and rates of organic pollutant transformation in the environment is a major challenge due to co-occurring transport and degradation processes. Measuring changes of stable isotope ratios (e.g. C-13/C-12, H-2/H-1, N-15/N-14) in individ ...

Toward the determination of joint volatility-hygroscopicity distributions: Development and response characterization for single-component aerosol

Athanasios Nenes

This work presents the development and characterization of a thermodenuder for the study and interpretation of aerosol volatility. Thermodenuder measurements are further combined with a continuous-flow streamwise thermal gradient CCN counter to obtain the ...

Electrochemical reduction of CO2 in organic solvents catalyzed by MoO2

Xile Hu, Heron Vrubel, Yeonji Oh, Sébastien Guidoux

MoO2 microparticles act as an active catalyst for the electrochemical reduction of CO2 in organic solvents such as acetonitrile and dimethylformamide. The catalytic activity and product selectivity depend on temperature and water content of the solvent. ...

Biogenic and biomass burning organic aerosol in a boreal forest at Hyytiala, Finland, during HUMPPA-COPEC 2010

Satoshi Takahama, Wuzhou Song

Submicron aerosol particles were collected during July and August 2010 in Hyytiala, Finland, to determine the composition and sources of aerosol at that boreal forest site. Submicron particles were collected on Teflon filters and analyzed by Fourier transf ...
