Journal ArticleDOI
Photochemically induced changes in dissolved organic matter identified by ultrahigh resolution fourier transform ion cyclotron resonance mass spectrometry.
Michael Gonsior,Barrie M. Peake,William T. Cooper,David C. Podgorski,Juliana D'Andrilli,William J. Cooper +5 more
TL;DR: The UV/vis absorbance and EEM fluorescence results supported this different photodegradation behavior, suggesting that the photoreactivity of CDOM is highly dependent on the molecular composition of the CDOM.
Journal ArticleDOI
Unifying Concepts Linking Dissolved Organic Matter Composition to Persistence in Aquatic Ecosystems.
Anne M. Kellerman,François Guillemette,David C. Podgorski,George R. Aiken,Kenna D. Butler,Robert G. M. Spencer +5 more
TL;DR: Across all sites and end-members studied, a consistent shift in composition with aging is found, highlighting the persistence of certain biomolecules concurrent with degradation time.
Journal ArticleDOI
21 Tesla FT-ICR Mass Spectrometer for Ultrahigh-Resolution Analysis of Complex Organic Mixtures
Donald F. Smith,David C. Podgorski,Ryan P. Rodgers,Greg T. Blakney,Christopher L. Hendrickson +4 more
TL;DR: This direct comparison reveals the continued need for higher mass-resolving power and better mass accuracy for comprehensive molecular characterization of the most complex organic mixtures.
Journal ArticleDOI
Heavy Petroleum Composition. 5. Compositional and Structural Continuum of Petroleum Revealed
David C. Podgorski,Yuri E. Corilo,Leonard Nyadong,Vladislav V. Lobodin,Benjamin J. Bythell,Winston K. Robbins,Amy M. McKenna,Alan G. Marshall,Ryan P. Rodgers +8 more
TL;DR: In this paper, a gap appears between the compositional space of asphaltenes and maltenes, in contradiction to the Boduszynski-Altgelt model, and a heavy distillate cut (atmospheric equivalent boiling point of 523-593 °C) is fractionated according to the number of aromatic rings by HPLC-2.
Journal ArticleDOI
Dissolved Organic Matter in Headwater Streams: Compositional Variability across Climatic Regions of North America
Rudolf Jaffé,Youhei Yamashita,Nagamitsu Maie,William T. Cooper,Thorsten Dittmar,Walter K. Dodds,Jeremy B. Jones,T. Myoshi,Jorge R. Ortiz-Zayas,David C. Podgorski,Akira Watanabe +10 more
TL;DR: In this article, the authors applied a multi-method analytical approach in an attempt to assess molecular characteristics of dissolved organic matter (DOM) and ultrafiltered DOM (UDOM) in headwater streams from different climatic regions in North America.
