Electrodeposition from supercritical fluids

Physical Chemistry Chemical Physics, 2014
Recent studies have shown that it is possible to electrodeposit a range of materials, such as Cu, Ag and Ge, from various supercritical fluids, including hydrofluorocarbons and mixtures of CO2 with suitable co-solvents. In this perspective we discuss the relatively new field of electrodeposition from supercritical fluids.

Brazilian Biomes as Promising Resources of Rhodotorula Yeasts for the Biotechnological Production of Carotenoids

Chemistry &Biodiversity, EarlyView.
ABSTRACT Yeasts belonging to the genus Rhodotorula are capable of synthesizing carotenoids, such as β‐carotene, γ‐carotene, torulene, torularodine, and astaxanthin. These carotenoids have been shown to offer health benefits to humans, such as immune system strengthening and a reduced risk of chronic degenerative diseases.
