A Photon Force and Flow for Dissipative Structuring: Application to Pigments, Plants and Ecosystems [PDF]
Entropy, 2022 Through a modern derivation of Planck’s formula for the entropy of an arbitrary beam of photons, we derive a general expression for entropy production due to the irreversible process of the absorption of an arbitrary incident photon spectrum in material ...

Microscopic dissipative structuring and proliferation at the origin of life [PDF]
Heliyon, 2017 Some fundamental molecules of life are suggested to have been formed, proliferated, and evolved through photochemical microscopic dissipative structuring and autocatalytic proliferation under the UV-C/UV-B solar environment prevalent at Earth’s surface ...

Dissipative Photochemical Abiogenesis of the Purines [PDF]
Entropy, 2022 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 Pigment World: Life’s Origins as Photon-Dissipating Pigments [PDF]
LifeMany of the fundamental molecules of life share extraordinary pigment-like optical properties in the long-wavelength UV-C spectral region. These include strong photon absorption and rapid (sub-pico-second) dissipation of the induced electronic excitation

Extreme and Topological Dissipative Solitons with Structured Matter and Structured Light
Nanomaterials, 2019 Structuring of matter with nanoobjects allows one to generate soliton-like light bundles with extreme characteristics—temporal duration and spatial dimensions. On the other hand, structuring of light gives the possibility to form light bundles with

Fatty Acid Vesicles as Hard UV-C Shields for Early Life
Foundations, 2023 Theories on life’s origin generally acknowledge the advantage of a semi-permeable vesicle (protocell) for enhancing the chemical reaction–diffusion processes involved in abiogenesis.
