Enrichment Factors of Perfluoroalkyl Oxoanions at the Air/Water Interface (2009)
Psillakis, Elefteria, Cheng, Jie, Hoffmann, M. R., Colussi, A. J.
The refractory, water-bound perfluoro-n-alkyl carboxylate F(CF_2)_nCO_2^− and sulfonate F(CF_2)_nSO_3^− surfactant anions reach remote locations by mechanisms that are not well understood. Here...
Cheng, Jie, Psillakis, Elefteria, Hoffmann, M. R., Colussi, A. J.
Perfluorooctanoate (PFO) and perfluorooctanesulfonate (PFOS) surfactant anions, once released, may rapidly reach remote regions. This phenomenon is puzzling because the water-bound anions of strong...
Enami, Shinichi, Hoffmann, M. R., Colussi, A. J.
Sulfenic acids (RSOH) are reactive intermediates in the oxidation of protein cysteines. Among cysteine oxoforms, RSOH represent redox-reversible species that can thus participate in regulation and...

Ozone Oxidizes Glutathione to a Sulfonic Acid (2009)
Enami, Shinichi, Hoffmann, M. R., Colussi, A. J.
Biosurfaces are universally covered with fluid microfilms containing reduced glutathione (GSH) and other antioxidants whose putative roles include the detoxification of ambient ozone (O_3). It is...
Vecitis, C. D., Park, H., Cheng, J., Mader, B. T., Hoffmann, M. R.
Acoustic cavitation driven by ultrasonic irradiation decomposes and mineralizes the recalcitrant perfluorinated surfactants perfluorooctanesulfonate (PFOS) and perfluorooctanoate (PFOA). Pyrolytic...
R.: Photoinduced oligomerization of aqueous pyruvic acid (2008)
M. I. Guzmán, A. J. Colussi, M. R. Hoffmann
The 320 nm-band photodecarboxylation of aqueous pyruvic acid (PA), a representative of the R-oxocarboxylic acids widely found in the atmospheric aerosol, yields 2,3-dimethyltartaric (A) and...
