The carbon speciation in the Earth’s interior as function of pressure, temperature and oxygen fugacity
… state of the Earth’s interior will influence the speciation of volatile elements both in the mantle and in mantle derived magmas. Carbon is one of the principal elements to be affected in this way because under reducing conditions it forms graphite or diamond, and under oxidizing conditions …

Mass, Composition, Source Identification and Impact Assessment for Fine and Coarse Atmospheric Particles in the Desert Southwest
… of ambient fine and coarse mass, ion, metal, and carbon concentrations at one-in-six day resolution was conducted at three sites from February 2009 to February 2010. Detailed organic carbon speciation was collected at 5-week resolution. A series of samples representing native soil, agricultural …

Hydrothermal liquefaction for energy recovery from high-moisture waste biomass
… functional group allocation, proton and carbon speciation, molecular weight distribution, boiling point distribution) were compared for the varying feedstocks as well as with published results for petroleum crudes and tar sand bitumens. Results demonstrated that although the biocrude oils …

Characterization, Speciation, and Source Apportionment of Particles inside and from the Exhaust of Public Transit Buses Fueled With Alternative Fuels
… that is investigated with respect to organic carbon (OC) and elemental carbon (EC) for public transit buses in Toledo, Ohio. The carbon source profile for both alternative fuels for eight carbon fractions is developed through real time experiments. The results indicated that the use of BD …
