Dark matter and dark energy: The critical questions [PDF]
, 2002 Stars account for only about 0.5% of the content of the Universe; the bulk of the Universe is optically dark. The dark side of the Universe is comprised of: at least 0.1% light neutrinos; 3.5% {+-} 1% baryons; 29% {+-} 4% cold dark matter; and 66% {+-} 6%

Dark energy–matter equivalence by the evolution of cosmic equation of state
, 2023 We consider a model-independent approach to constrain the equivalence redshift, z e q , at which dark energy and the total matter (cold dark matter and baryonic) equate their magnitudes.

Advanced Engineering Materials, EarlyView.Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.
