Thermodynamic dissipation theory for the origin of life

K Michaelian - Earth System Dynamics, 2011 - esd.copernicus.org
Understanding the thermodynamic function of life may shed light on its origin. Life, as are all
irreversible processes, is contingent on entropy production. Entropy production is a …

Metallic bonding and cluster structure

JM Soler, MR Beltrán, K Michaelian, IL Garzón… - Physical Review B, 2000 - APS
Abstract Knowledge of the structure of clusters is essential to predict many of their physical
and chemical properties. Using a many-body semiempirical Gupta potential (to perform …

[HTML][HTML] Non-equilibrium thermodynamic foundations of the origin of life

K Michaelian - Foundations, 2022 - mdpi.com
There is little doubt that life’s origin followed from the known physical and chemical laws of
Nature. The most general scientific framework incorporating the laws of Nature and …

Thermodynamic stability of ecosystems

K Michaelian - Journal of theoretical biology, 2005 - Elsevier
The stability of ecosystems during periods of stasis in their macro-evolutionary trajectory is
studied from a non-equilibrium thermodynamic perspective. Individuals of the species are …

Fundamental molecules of life are pigments which arose and co-evolved as a response to the thermodynamic imperative of dissipating the prevailing solar spectrum

K Michaelian, A Simeonov - Biogeosciences, 2015 - bg.copernicus.org
The driving force behind the origin and evolution of life has been the thermodynamic imperative
of increasing the entropy production of the biosphere through increasing the global solar …

[HTML][HTML] The non-equilibrium thermodynamics of natural selection: from molecules to the biosphere

K Michaelian - Entropy, 2023 - mdpi.com
Evolutionary theory suggests that the origin, persistence, and evolution of biology is driven
by the “natural selection” of characteristics improving the differential reproductive success of …

[HTML][HTML] The dissipative photochemical origin of life: UVC abiogenesis of adenine

K Michaelian - Entropy, 2021 - mdpi.com
The non-equilibrium thermodynamics and the photochemical reaction mechanisms are
described which may have been involved in the dissipative structuring, proliferation and …

Negative heat capacity of sodium clusters

JA Reyes-Nava, IL Garzón, K Michaelian - Physical Review B, 2003 - APS
Heat capacities of Na N, N= 13, 20, 55, 135, 142, and 147, clusters have been investigated
using a many-body Gupta potential and microcanonical molecular-dynamics simulations. …

[PDF][PDF] Microscopic dissipative structuring and proliferation at the origin of life

K Michaelian - Heliyon, 2017 - cell.com
Some fundamental molecules of life are suggested to have been formed, proliferated, and
evolved through photochemical microscopic dissipative structuring and autocatalytic …

Size-dependent fivefold and icosahedral symmetry in silver clusters

X Xing, RM Danell, IL Garzón, K Michaelian, MN Blom… - Physical Review B, 2005 - APS
Trapped ion electron diffraction measurements on silver cluster cations, Ag n+ for sizes n=
36–46, 55 at∼ 120 K describe an evolution in structural symmetry with increasing cluster size. …
