Analysis of functional groups in atmospheric aerosols by infrared spectroscopy: systematic intercomparison of calibration methods for US measurement network samples

Peak fitting (PF) and partial least squares (PLS) regression have been independently developed for estimation of functional groups (FGs) from Fourier transform infrared (FTIR) spectra of ambient aerosol collected on Teflon filters. PF is a model that quant ...

Analysis of Aerosol in Zurich by Infrared Spectroscopy and Statistical Modelling

Satoshi Takahama, Giulia Ruggeri, Matteo Reggente

Atmospheric particulate matter (PM) has been associated with increased morbidity and mortality, reduced visibility, and is one of the least understood components of the climate system. We use the Fourier transform infrared (FT-IR) absorbance spectra of atm ...

Multi Seasonal Functional Group Analysis by FT-IR Spectroscopy of Atmospheric Aerosol in Zurich

Satoshi Takahama, Matteo Reggente

Atmospheric particulate matter (PM) has been associated with increased morbidity and mortality, reduced visibility, and is one of the least understood components of the climate system. Organic matter (OM) constitutes a substantial fraction (up to 80%) of P ...

Analysis of functional groups in atmospheric aerosols by infrared spectroscopy: sparse methods for statistical selection of relevant absorption bands

Satoshi Takahama, Giulia Ruggeri

Various vibrational modes present in molecular mixtures of laboratory and atmospheric aerosols give rise to complex Fourier transform infrared (FT-IR) absorption spectra. Such spectra can be chemically informative, but they often require sophisticated algo ...

Functional group distribution of secondary organic aerosol generated using the Master Chemical Mechanism: similarities and discrepancies with environmental controlled chamber studies

Satoshi Takahama, Giulia Ruggeri, Fabian Alexander Bernhard, Sarah Elizabeth Shipley

In this work, composition of organic aerosol simulated by the Master Chemical Mechanism coupled with a dynamic absorptive partitioning model is compared against infrared spectroscopy measurements of functional group abundance in chamber experiments. The Ma ...

Sub-ppm detection of vapors using piezoresistive microcantilever array sensors

Terunobu Akiyama, Peter Vettiger, Laure Aeschimann, Christoph Gerber

The performance of microfabricated piezoresistive cantilever array sensors has been evaluated using various vapors of volatile organic compounds including alkanes with different chain length from 5 (n-pentane) to 14 (n-tetradecane). We demonstrate that pie ...

Relative Basicities of ortho-, meta-, and para-Substituted Aryllithiums

The relative basicities of aryllithiums bearing methoxy, chlorine, fluorine, trifluoromethyl and trifluoromethoxy substituents at the ortho, meta, and para positions have been assessed. To this end, two aryllithiums of comparable basicity were equilibrated ...
