Separation or formulation of products by supercritical fluids and production of substances and composites with unique properties and characteristics for the use in different applications are nowadays intensively studied. One of the most important advantages using supercritical fluids is selective extraction of components or fractionation of total extracts. As yet, industrial dense gas extractio...

Abstract The urge for a sustainable and non-polluting industry has raised the need search an alternative insulating fluid that could be used in transformers, because of negative environmental effect mineral-based fluids. Natural esters from non-edible oil seeds showed to feasible alternative, unfortunately they possess poor thermooxidative properties. Neem trees grow nearly on all types soils c...
