The existence of the Hoyle state is essential for the nucleosynthesis of carbon in helium-burning red giant stars, and predicts an amount of carbon production in a stellar environment which matches observations. The existence of the Hoyle state has been confirmed experimentally, but its precise prop...
Intramolecular 15N and 18O fractionation in the reaction of N2O with O(1D) and its implications for the stratospheric N2O isotope signature [1] Atmospheric nitrous oxide (N2O) is enriched in heavy oxygen and nitrogen isotopes relative to its tropospheric sources. This enrichment is traced back ....
Although carbon isotope reversal and its reasons in shale gas reservoirs have been widely recognized, the application of the reversal is yet to be investigated. A study on high-maturity shale from Wufeng and Longmaxi Formations in the Sichuan Basin not only reveals the relationship between the deg...
Black carbon (BC) is produced by incomplete combustion of biomass by wildfires and burning of fossil fuels. BC is environmentally persistent over centuries to millennia, sequestering carbon in marine and terrestrial environments. However, its production, storage and dynamics, and therefore its role in...
The evolution of the C and O isotopes in our Galaxy is studied, on the basis of recent results of stellar nucleosynthesis and recent models for the chemical evolution of the galactic disk. It is found that has a mixed primary and secondary origin, the former presumably from hot-bottom burnin...

GC Wright,KT Hubick,GD Farquhar - Stable Isotopes and Plant Carbon-water Relations 被引量: 129发表: 1993年 Carbon Isotope Discrimination and Plant Water-Use Efficiency It has been known for a long time that the isotope fractionation of carbon formed by photosynthesizing plants varies radically dep...
The Baltoscandian and North American (Nevada) δ 13C trends are in general lines very similar, providing good prospects for global chemostratigraphical correlation and understanding of role of oceanic processes in carbon cycling. 展开 关键词: Baltoscandia Carbon isotopes Chemostratigraphy North America...
Evolution of organic carbon isotopes during the pyrolysis of Nongan oil shale in Songliao Basin and its implications for in-situ conversion project The purpose of this paper is to identify the dynamic evolution characteristics of carbon isotope fractionation during the evolution of oil shale pyrolysis...
