Diffusion of hydrocarbons diluted in supercritical carbon dioxide
Scientific Reports, 2023 AbstractMutual diffusion of six hydrocarbons (methane, ethane, isobutane, benzene, toluene or naphthalene) diluted in supercritical carbon dioxide ($${\hbox {CO}}_{2}$$ CO 2 ) is studied by molecular dynamics simulation near the Widom line, i.e., in the ...

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Astaxanthin is a carotenoid with strong antioxidant properties, used in research on cancer treatment, ocular injuries, and neurological disorders. When produced by the microalgae Haematococcus lacustris, its antioxidant potential is even higher than that of the synthetic molecule, making it particularly attractive for pharmaceutical and ...
