Abstract: We have proposed that the abiogenesis of life around the beginning of the Archean may have been an example of “spontaneous” microscopic dissipative structuring of UV-C pigments under the prevailing surface ultraviolet solar spectrum. The thermodynamic function of these Archean
Jul 26, 2022 · Our theory therefore affirms that the “fundamental molecules of life” (those in the three domains of life) were, at their origin, microscopic photon dissipative structures (i.e., pigments) which arose “spontaneously” under the thermodynamic imperative to dissipate the prevailing UV-C (210–285 nm) solar photon spectrum (Figure 1) [14 ...

Michaelian has shown, using the formalism of non-linear irreversible thermodynamics, that there would have existed during the Archean a thermodynamic imperative to the abiogenic UV-C photochemical synthesis and proliferation of these pigments over the entire Earth surface, as well as to their complexation, if this improved their
Mar 1, 2024 · This section provides an overview of the impact of UV-light-driven transformations for the development of visible-light-mediated photocatalysis 6, 8. UV-light direct excitation has long provided a ...
of life has been the thermodynamic imperative of increasing the entropy production of the biosphere through increasing the global solar photon dissipation rate. In the upper atmo-sphere of today, oxygen and ozone derived from life pro-cesses are performing the short-wavelength UV-C and UV-B dissipation. On Earth’s surface, water and organic ...

Oct 1, 2017 · This arises from a non-equilibrium thermodynamic imperative to increase entropy production, i.e. to increases in the spread of the conserved quantities of Nature (energy, momentum, angular momentum, charge, etc.) over ever more microscopic degrees of freedom.
