This work examines the stable isotope fractionation of carbon and oxygen in gaseous, supercritical, and liquid carbon dioxide systems at temperatures from -27.1 to +43.5 °C.
View Article and Find Full Text PDFPure gases and mixtures containing stable isotopes are used in a wide variety of applications including health care, food authentication, geochemistry, and environmental monitoring. It is therefore important to understand the role of moisture, which is one of the most critical impurities in compressed gas mixtures and pure gases, in their stability. Gaseous carbon dioxide (CO) was used as a proxy for the evaluation of the effects of its isotopic composition, when in contact with moisture throughout the depletion of a cylinder's contents, as well as pressure regulation and long-term stability.

- The Antarctic ice cap plays a crucial role in influencing global ocean circulation and climate, but evidence of its glacial history is limited.
- New research focuses on sulfates found in glaciogenic deposits from the Lewis Cliff Ice Tongue, revealing distinct isotope signatures that provide insights into past environmental conditions.
- These findings suggest that ice-free cold deserts may have existed in Antarctica since the Miocene, indicating a fluctuating ice sheet size while maintaining a hydrological cycle similar to today's.
