Characterization of primary and aged wood burning and coal combustion organic aerosols in an environmental chamber and its implications for atmospheric aerosols

Satoshi Takahama, Imad El Haddad, Nikunj Dudani, Amir Yazdani

Particulate matter (PM) affects visibility, climate, and public health. Organic matter (OM), a uniquely complex portion of PM, can make up more than half of total atmospheric fine PM mass. We investigated the effect of aging on secondary organic aerosol (S ...

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

Satoshi Takahama, Matteo Reggente

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 ...

Iron-coated polymer films with high antibacterial activity under indoor and outdoor light, prepared by different facile pre-treatment and deposition methods

César Pulgarin, Sami Rtimi, Stefanos Giannakis, Ania Schärer

In the present work, we study the fabrication of self-cleaning antibacterial surfaces, active under indoor or outdoor light. In order to obtain the highest activity with the lowest complexity we assess mild conditions of preparation (temperatures), pre-tre ...

Improved mechanical dispersion or use of coupling agents? Advantages and disadvantages for the properties of fluoropolymer/ceramic composites

Véronique Michaud, Yves Leterrier, Dragan Damjanovic, Sara Dalle Vacche

The aim of this work is to investigate the influence of interfacial chemistry on the properties of fluoropolymer composites, independent of effects derived from changes in morphology, in particular particle dispersion state. A comparative study of solvent ...

Quantification of amine functional groups and their influence on OM/OC in the IMPROVE network

Satoshi Takahama

Recently, we developed a method using FT-IR spectroscopy coupled with partial least squares (PLS) regression to measure the four most abundant organic functional groups, aliphatic C-H, alcohol OH, carboxylic acid OH and carbonyl C = O, in atmospheric parti ...

Direct Imaging of Dopant Distribution in Polycrystalline ZnO Films

Christophe Ballif, Cécile Hébert, Aïcha Hessler-Wyser, Duncan Thomas Lindsay Alexander, Stéphane Laurent Escrig, Sylvain Nicolay, Monica Morales Masis, Martin Ledinsky, Arthur Brian Aebersold

Two fundamental requirements of transparent conductive oxides are high conductivity and low optical absorptance, properties strongly dependent on the free-carrier concentration of the film. The free carrier concentration is usually-tuned by the addition of ...

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 ...

On the functional group composition of organic aerosol

Giulia Ruggeri

Atmospheric aerosol is ubiquitous and its impact on climate and health has not been fully understood yet. Multiple diverse processes and sources lead to atmospheric aerosol formation and emission and this reflects on its heterogeneity in chemical compositi ...

Potential exposure routes and accumulation kinetics for poly- and perfluorinated alkyl compounds for a freshwater amphipod: Gammarus spp. (Crustacea)

Gammarids were exposed to sediments from a deposition site located on the Rhone River (France) downstream of a fluoropolymer manufacturing plant. Gammarids accumulated to various extents four long-chain perfluoroalkyl carboxylic acids (PFCAs) from C-9 to C ...
