How and where did life on Earth originate? To date, various environments have been
proposed as plausible sites for the origin of life. However, discussions have focused on a …

Transport of carbon dioxide (CO 2) via pipeline from the point of capture to a geologically
suitable location for either sequestration or enhanced hydrocarbon recovery is a vital aspect …

Saturn's moon Enceladus has an ice-covered ocean; a plume of material erupts from cracks
in the ice. The plume contains chemical signatures of water-rock interaction between the …

In the context of Underground Hydrogen Storage (UHS), the stored gas is in direct contact
with brine (residual brine from the cavern or formation water of deep aquifers). Therefore …

5-(Hydroxymethyl) furfural (HMF) and levulinic acid production from glucose in a cascade of
reactions using a Lewis acid (CrCl3) catalyst together with a Brønsted acid (HCl) catalyst in …

Soil microorganisms globally are thought to be sustained primarily by organic carbon
sources. Certain bacteria also consume inorganic energy sources such as trace gases, but …

The development of highly accurate and computationally efficient modeling software based
on Gibbs energy minimization (GEM) makes it possible to thermodynamically simulate …

Recent advances in theoretical geochemistry permit calculation of the standard molal
thermodynamic properties of a wide variety of minerals, gases, aqueous species, and …

Abiotic hydrocarbons and carboxylic acids are known to be formed on Earth, notably during
the hydrothermal alteration of mantle rocks. Although the abiotic formation of amino acids …

Abstract The Eu 3+ Eu 2+ redox boundary for temperatures up to 600° C and pressures up
to 4000 bar has been calculated using the “revised HKF model” for the prediction of the …
