The biogeochemical cycling of soil organic matter (SOM) plays a central role in regulating
soil health, water quality, carbon storage, and greenhouse gas emissions. Thus, many …

Dissolved organic matter (DOM) contains complex molecular compounds that dominate its
heterogeneous dynamics and behaviors in aquatic environments. Fourier transform ion …

We describe complex organic mixture analysis by 21 tesla (T) Fourier transform ion cyclotron
resonance mass spectrometry (FT-ICR MS). Ultrahigh mass-resolving power (m/Δ m 50%> 2 …

Wildfires in forested watersheds dramatically alter stored and labile soil organic matter
(SOM) pools and the export of dissolved organic matter (DOM). Ecosystem recovery after …

A new strategy has been developed for characterization of the most challenging complex
mixtures to date, using a combination of custom-designed experiments and a new data pre …

Obesity and diabetes arise from an intricate interplay between both genetic and
environmental factors. It is well recognized that obesity plays an important role in the …

Chemical characterization of petroleum is a challenging task due to its inherently complex
nature. For example, crude oil is believed to have as many or more compounds than the …

The detailed molecular characterization of petroleum-related samples by mass
spectrometry, often referred to as petroleomics, continues to present significant analytical …

METHODS Herein we describe alternative dissociation methods commonly employed within
mass spectrometry with an emphasis on the outcomes of probing native protein complexes …

Given the ill-defined term “naphthenic acids”(NAs), we will classify NAs as the carboxylic
acids found naturally in crude oil, which include both classic NAs (c-NAs, monoacids) and ox …
