Supercritical Technologies for the Valorization of Wine Industry By-Products
… wine industry by products; particularly on the extraction and characterization of grape seeds oil using supercritical CO2 (SC-CO2) and polyphenols from grape skins and defatted grape seeds using subcritical water (SW) and then, modeling of the kinetics of extractions and process economic …

Determination of Extractables from Cranberry Seeds Using Supercritical CO₂
An alternative method for extraction of therapeutically beneficial compounds such as sterols, fatty acids, and tocopherols from cranberry seeds with pure SF CO2 has been provided. The supercritical fluid extraction (SFE) operating conditions such as extraction temperature, pressure of CO2, …

Glycerol from novel strains of halophytic microalgae
… using novel supercritical carbon dioxide (SC-CO2) extraction technology. Dunaliella and Asteromonas strains were shown to withstand large variations in the salinity of the growth medium 0.5 - 4.0 M NaCl. The optimum conditions for their growth were 1.0 M NaCl, 30 oC, pH 7.5 to 9.0 and 45 μmol …

Process-morphology-property Relationships in Strut-like Poly(ether ether ketone) Aerogels Prepared through Thermally Induced Phase Separation
… vacuum-drying, freeze-drying, and supercritical CO2 extraction with minimal shrinkage and deformation. The weaker globular PEEK aerogel morphologies suffered from considerable shrinkage due to capillary forces or ice crystal growth induced on vacuum-drying or freeze-drying, respectively. …

Characterization of Methyltrimethoxysilane Sol-Gel Polymerization and the Resulting Aerogels.
… were suggested. Aerogels dried by supercritical CO2 extraction were characterized by FTIR, 13C and 29Si solid-state NMR and nitrogen sorption. The existence of three residual groups (Si-OH, Si-OCH3, and Si-OC2H5) was confirmed, but their concentrations are very low compared to silica aerogels. …

Evaluation of biomass from the halotolerant microalga Dunaliella salina as an animal feed additive with immune-modulatory activity
… and this is growing at ~4 % p.a. Supercritical CO2 extraction of high-value carotenoids yields a solvent-free defatted powder. This material was sourced from biomass cultivated across different seasons from two different cultivation sites, namely a coastal Mediterranean site, which used seawater …

Supercritical Fluid Extraction Directly Coupled with Reversed Phase Liquid Chromatography for Quantitative Analysis of Analytes in Complex Matrices
… for on-line coupling of Supercritical Fluid Extraction (SFE) with High Performance Reversed Phase Liquid Chromatography (HP-RPLC), and to explore its ability for quantitative analysis of analytes in different matrices. First, a simple interface was developed via a single one six-port …
