Metal Catalysis Acting on Nitriles in Early Earth Hydrothermal Systems

Hydrothermal systems are areas in which heated fluids and organic molecules rush through basaltic material rich in metals and minerals. By studying malononitrile and acetonitrile, we examine the effects of […]

Life In The Smoke Of Underwater Volcanoes

Deep down in the ocean at tectonic plate boundaries, hot fluids rise from so-called hydrothermal vents. The fluids are devoid of oxygen and contain large amounts of metals such as […]

Stability of DL-Glyceraldehyde under Simulated Hydrothermal Conditions: Synthesis of Sugar-like Compounds in an Iron(III)-Oxide-Hydroxide-Rich Environment under Acidic Conditions

Researchers have suggested that the condensation of low-molecular-weight aldehydes under basic conditions (e.g., pH > 11) is the prebiotic reaction responsible for the abiotic formation of carbohydrates.
