Only two of the 12 objects appeared to have normal levels of CO absorption. We interpret this as evidence of low carbon abundances. In addition, we detect CO absorption in four of the 12 objects. Depleted levels of C and enhanced levels of C indicate that material that has been processed ...
Several species of Chamaecrista from section absus and species of Stryphnodendron had carbon contents of 50-55%, higher than previously reported for leaves. This was coupled with low (1-3%) ash contents. The13C values of plants with ≥49% C were significantly more negative than those ...
The low (1.1%) natural abundance of 13C often requires administration of supplementary labeled compounds to obtain adequate signal strength. Only certain storage compounds that are rich in carbon, such as triacylglycerols or glycogen, can be directly detected by 13C MRS unless small-bore and high...
The 12C/13C ratio in the present near-solar interstellar medium has been found to be 70±10, interpreted as reflecting “galactic chemical evolution” over the age of the solar system (Prantzos et al., 1996). Isotopic measurement of solar-wind carbon in lunar soils has not produced ...
Since its founding in 1994, XPRIZE has launched over $250 million of competitions to create radical breakthroughs that benefit humanity. Most recently, Peter teamed up with Elon Musk to launch a $100 million XPRIZE focused on combating climate change through gigaton carbon removal. Peter’s life ...
