Reactivity of Wet scCO toward Reservoir and Caprock Formations under Elevated Pressure and Temperature Conditions: Implications for CCS and CO-Based Geothermal Energy Extraction.

Carbon capture and storage (CCS) and CO-based geothermal energy are promising technologies for reducing CO emissions and mitigating climate change. Safe implementation of these technologies requires an understanding of how CO interacts with fluids and rocks at depth, particularly under elevated pressure and temperature. While CO-bearing aqueous solutions in geological reservoirs have been extensively studied, the chemical behavior of water-bearing supercritical CO remains largely overlooked by academics and practitioners alike.

Rapid High-Sensitivity Analysis of Methane Clumped Isotopes (ΔCHD and ΔCHD) Using Mid-Infrared Laser Spectroscopy.

Mid-infrared laser absorption spectroscopy enables rapid and nondestructive analysis of methane clumped isotopes. However, current analytical methods require a sample size of 20 mL STP (0.82 mmol) of pure CH gas, which significantly limits its application to natural samples.

Exploring air pollution awareness: insights from interviews with technology enthusiasts using wearable monitoring devices.

This study aims to investigate shifts in awareness regarding air pollution and its correlation with interest in using wearable devices for air quality monitoring. 16 healthy participants, predominantly engineers, residing or studying in Milan, were interviewed to assess their knowledge and interest in air pollution. Participants then walked a predefined route of 4.

Effect of a giant meteorite impact on Paleoarchean surface environments and life.

Large meteorite impacts must have strongly affected the habitability of the early Earth. Rocks of the Archean Eon record at least 16 major impact events, involving bolides larger than 10 km in diameter. These impacts probably had severe, albeit temporary, consequences for surface environments.
