Hydrothermal technologies are broadly defined as chemical and physical transformations in
high-temperature (200–600° C), high-pressure (5–40 MPa) liquid or supercritical water. This …

The aim of the present article is to review some of the common corrosion phenomena and
describe the predominant corrosion mechanisms in high-temperature and supercritical …

The use of hydrogen (H2) as a substitute for fossil fuel, which accounts for the majority of the
world's energy, is environmentally the most benign option for the reduction of CO2 …

In recent years, serpentinized ultramafic rocks have received considerable attention as a
source of H2 for hydrogen-based microbial communities and as a potential environment for …

Water is not restricted to moderate temperatures and low pressures, but can exist up to very
high temperatures, far above its critical point at 647 K. In this supercritical regime, water can …

Fluids circulating through actively serpentinizing systems are often highly enriched in
methane (CH4). In many cases, the CH4 in these fluids is thought to derive from abiotic …

Topologic relations indicate that the lowest relative oxygen fugacity attained in magnetite-
bearing serpentinites occurs in the presence of the assemblage serpentine-olivine-brucite …

The search for exoplanets includes the promise to eventually find and identify habitable
worlds. The thousands of known exoplanets and planet candidates are extremely diverse in …

The concept that aqueous CO2 can be reduced to hydrocarbons abiotically during
serpentinization of olivine has become widespread in the earth and planetary sciences. This …

The solubility of gold has been measured in aqueous sulphide solutions from 100 to 500° C
at 500 bar in order to determine the stability and stoichiometry of sulphide complexes of gold …
