Prebiotic Chemistry in Nanoconfinement [PDF]
, 2016 Water presents extremely different properties depending not only on conditions like temperature and pressure but also on the local environment (bulk vs. interfacial water), which in turn profoundly affects chemical reactions in solution. Here, we present the results of extensive ab initio molecular dynamics and metadynamics simulations in which we ...

Can prebiotic reaction systems survive in the wild? An interference chemistry approach [PDF]
, 2021 The origin of life occurred by a series of prebiotic reaction pathways (collectively a system) hosted in one or more geochemical environments (together forming an origin of life scenario).

The Future of Prebiotic Chemistry
ACS Central Science, 2016 Two recent papers reporting advances in our understanding of how a protometabolism may have developed in a prebiotic world add new meaning to the theme “First Reactions” and highlight the challenges facing synthetic organic chemists attempting to retrodict the origins of life.

Prebiotic Chemistry of Pluto [PDF]
Astrobiology, 2019 We present the case for the presence of complex organic molecules, such as amino acids and nucleobases, formed by abiotic processes on the surface and in near-subsurface regions of Pluto. Pluto's surface is tinted with a range of non-ice substances with colors ranging from light yellow to red to dark brown; the colors match those of laboratory organic ...

A robotic prebiotic chemist probes long term reactions of complexifying mixtures
Nature Communications, 2021 The transition of prebiotic chemistry to present-day chemistry lasted a very long period of time, but the current laboratory investigations of this process are mostly limited to a couple of days.
