HCN polymerization is one of the most important and fascinating reactions in prebiotic chemistry, and interest in HCN polymers in the field of materials science is growing. However, little is known about the kinetics of the HCN polymerization process

The influence of the reaction conditions in the synthesis of HCN polymers in water at low temperature has been analyzed. The thermal stability of the HCN polymers obtained from aqueous solutions and under inert atmosphere was evaluated by thermogravi

The conditions for the potential abiotic formation of organic compounds from inorganic precursors have great implications for our understanding of the origin of life on Earth and for its possible detection in other environments of the Solar System. I

The origin of life is one of the fundamental questions in science. Eschenmoser proposed the "glyoxylate scenario", in which plausible abiotic synthesis pathways were suggested to be compatible with the constraints of prebiotic chemistry. In this prop

The genesis of life on Earth is a hypothesis of evolutionary science that can be, at least partially, tested experimentally. The prebiotic synthesis of cofactors or coenzymes is a poorly explored issue, likely because their formation under plausible

Elucidating the origin of life involves synthetic as well as analytical challenges. Herein, for the first time, we describe the use of gel electrophoresis and ultrafiltration to fractionate HCN polymers. Since the first prebiotic synthesis of adenine

The origin of nucleobases and other heterocycles is a classic ques- tion in the chemistry of the origins of life. The construction of laboratory models for the abiotic synthesis of ni- trogen heterocycles in plausible natural conditions also aids the

A crystalline ice matrix at subzero temperatures can maintain a liquid phase where organic solutes and salts concentrate to form eutectic solutions. This concentration effect converts the confined reactant solutions in the ice matrix, sometimes makin
