Study of Ferrocyanide Adsorption onto Different Minerals as Prebiotic Chemistry Assays.

Astrobiology, 2021
Considered one of the most promising building blocks of life on primitive Earth, cyanide and its complexes are likely to have played an important role in the emergence of life on the planet.

Prebiotic chemistry: From dust to molecules and beyond

2022
Prebiotic chemistry has dominated the origins of life (OoL) field to such an extent that often these terms have been used interchangeably. While prebiotic chemistry has benefited from cross-seeding with other disciplines (e.g., biochemistry, biophysics, computational sciences, geosciences), the OoL problem is still primarily a chemical one.

Materials Synthesis and Catalysis in Microfluidic Devices: Prebiotic Chemistry in Mineral Membranes

ChemCatChem, 2020
The processes that led to the origins of life possibly occurred in the inorganic precipitate membranes of alkaline hydrothermal vents. These geochemical systems provide spatial confinement, cross‐membrane gradients, and catalytic surfaces.

Meteorites as Catalysts for Prebiotic Chemistry

Chemistry – A European Journal, 2013
OH (2:1 v/v), and sulfu-ric acid. In the case of chondrites, achondrites, and stony-iron meteorites, the samples were also pyrolyzed at 6008C.After the treatment, the powders did not release any traceof organic substances. The synthesis of large number of com-pounds was observed (Scheme 1): nucleobases and their an-alogues, carboxylic acids, amino ...

The cometary contribution to prebiotic chemistry

Advances in Space Research, 1992
Different estimates based on dynamical considerations, lunar cratering rates, Solar System chemical abundances, and the single-impact theory on the origin of the Earth-Moon system suggest that comets and other related small, volatile-rich primitive minor bodies captured by the Earth during the early Archean must have been a major source of volatiles on

Adenine Adsorbed onto Montmorillonite Exposed to Ionizing Radiation: Essays on Prebiotic Chemistry.

Astrobiology, 2020
Most adsorption and radiolysis experiments related to prebiotic chemistry studies are performed in distilled water or sodium chloride solutions. However, distilled water and sodium chloride solutions do not represent the composition of the primitive seas

The importance of prebiotic chemistry in the RNA World

Current Opinion in Chemical Biology, 2004
In vitro selection experiments have clearly demonstrated that RNA can perform many of the functions necessary to support an RNA world. Moreover, it appears that novel functions could have readily evolved from existing functional RNA molecules. Therefore, diverse molecular ecosystems could potentially have arisen from an initial, small population of ...
