The solution-mediated formation of calcium sulfate minerals, ie gypsum, anhydrite and
bassanite, is a common process in both natural and engineered settings. It plays a key role …

Sulfur has been widely used for centuries as a staple for pest and disease management in
agriculture. Presently, it is the largest‐volume pesticide in use worldwide. This review …

Drinking water is limited in quantity and quality in fast-growing cities in developing countries.
Water quality has been impacted by competing demands by industry, municipal supplies …

In-situ analyses reveal the presence of hydrogen within calcium sulfate veins crosscutting
the sediments found in Gale crater. Laboratory experiments were performed to calibrate the …

Although sulfur cycling in acid mine drainage (AMD)-contaminated rice paddy soils is critical
to understanding and mitigating the environmental consequences of AMD, potential sources …

Water activity is an important characteristic for describing unusual waters and is a
determinant of habitability for microorganisms. However, few empirical studies of water …

Driving forces for natural soil salinity and alkalinity are climate, rock weathering, ion
exchange, and mineral equilibria reactions that ultimately control the chemical composition …

Life is based on informational polymers such as DNA or RNA. For their polymerization, high
concentrations of complex monomer building blocks are required. Therefore, the dilution by …

Observations of the Martian surface from orbiting spacecraft and in situ landers and rovers,
as well as analyses of Martian meteorites in terrestrial laboratories, have consistently …

Jarosite and other metal sulphates are common on Mars and are interpreted to have formed
in an extreme acidic saline aqueous environment, similar to modern Earth analogues where …
