Atmospheric Prebiotic Chemistry and Organic Hazes [PDF]
Earth's atmospheric composition at the time of the origin of life is not known, but it has often been suggested that chemical transformation of reactive species in the atmosphere was a significant source of prebiotic organic molecules. Experimental and theoretical studies over the past half century have shown that atmospheric synthesis can yield ...

Prebiotic Chemistry: Geochemical Context and Reaction Screening [PDF]
The origin of life on Earth is widely believed to have required the reactions of organic compounds and their self- and/or environmental organization. What those compounds were remains open to debate, as do the environment in and process or processes by ...

Heat flows solubilize apatite to boost phosphate availability for prebiotic chemistry [PDF]
Phosphorus is an essential building block of life, likely since its beginning. Despite this importance for prebiotic chemistry, phosphorus was scarce in Earth’s rock record and mainly bound in poorly soluble minerals, with the calcium-phosphate mineral ...

Gas-phase prebiotic chemistry in extraterrestrial environments [PDF]
AbstractA variety of molecular species up to complex polyatomic molecules/radicals have been identified in many extraterrestrial gaseous environments, including interstellar clouds, cometary comae and planetary atmospheres. Amongst the identified molecules/radicals, a large percentage are organic in nature and encompass also prebiotic molecules ...

Do-Nothing Prebiotic Chemistry: Chemical Kinetics as a Window into Prebiotic Plausibility
Origin of Life research is a fast growing field of study with each year bringing new breakthroughs. Recent discoveries include novel syntheses of life's building blocks, mechanisms of activation and interaction between molecules, and newly identified environments that provide promising conditions for these syntheses and mechanisms.

An activated carbon catalyst having weak acid sites hydrolyzes chitin to chitin‐oligosaccharides selectively in the presence of mechanical milling. Our system preferentially cleaves large molecules over small oligomers, thus maximizing the selectivity and yield of chitin‐oligosaccharides.

Prebiotic Chemistry Experiments Using Microfluidic Devices
Microfluidic devices are small tools mostly consisting of one or more channels, with dimensions between one and hundreds of microns, where small volumes of fluids are manipulated. They have extensive use in the biomedical and chemical fields; however, in

The protometabolic nature of prebiotic chemistry
This tutorial review revises the main synthetic pathways of prebiotic chemistry, suggesting how they could be wired through common intermediates and catalytic cycles, as well as the boundary conditions under which they would become protometabolic.
