Molecular Dynamics Study on CO2 Storage in Water-Filled Kerogen Nanopores in Shale Reservoirs: Effects of Kerogen Maturity and Pore Size [PDF]
, 2020 CO2 sequestration in shale reservoirs is an economically viable option to alleviate carbon emission. Kerogen, a major component in the organic matter in shale, is associated with a large number of nanopores, which might be filled with water. However, the

Earth and Space Science, Volume 13, Issue 7, July 2026.Abstract Mars Sample Return (MSR) is the next major frontier in Mars exploration, through which advanced laboratory instrumentation will be used to study Martian samples and answer key questions surrounding Mars' planetary evolution and astrobiology. Non‐destructive, high‐resolution imaging will be critical for preliminary MSR analyses.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.Abstract Natural hydrogen (H2) is a promising clean energy resource and a significant component of geothermal gases, yet its origins and release mechanisms remain poorly constrained. Here, we present geochemical and isotopic data (CO2, N2, Ar, H2, He, CH4, 3He/4He, δ13C‐CO2, and δ13C‐CH4) for hydrothermal gases from the Changning–Menglian suture (CMS),

Archaeal Tetraether Lipids as Tracers for Past Marine Environmental Change
Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.Abstract Archaea are single‐celled microorganisms that are abundant in marine environments and play a key role in the carbon and nitrogen cycles. Archaea can biosynthesize a wide variety of isoprenoid membrane lipids, including isoprenoid glycerol dibiphytanyl glycerol tetraethers (isoGDGTs).
