Summary: The effect of high-pressure treatment with supercritical CO2 on the inactivation of Listeria innocua in fish soup was investigated. The study found that higher pressure, temperature, and CO2 levels resulted in more significant inactivation of L. innocua. Additionally, the combination of high pressure and CO2 levels inhibited the recovery of L. innocua.

Summary: In this study, a lipophilic ophthalmic drug, lutein, was encapsulated in liposomes using a supercritical assisted process. The effects of pressure, temperature, and drug to lipid ratio on mean diameters and lutein encapsulation efficiency were investigated. The release of lutein from liposomes was significantly influenced by temperature, with higher temperatures resulting in faster drug release.

Summary: Space confined reactions are a viable strategy for achieving important properties in functional materials. Various systems for confinement have been reported, but the focus has primarily been on the concept of space confinement while neglecting the changes in confined space itself. Supercritical CO2 has the potential to reveal structural changes in confined spaces, known as the anti-nanoconfinement effect, which can lead to a series of variations in electronic band and structural transformation.

Summary: This study investigated the reaction between hydrated portland cement and supercritical CO2 at different temperature and pressure levels to understand the long-term durability prediction of concrete in wellbore environment. Experimental results showed an increase in aragonite amount with higher temperature and pressure, while the opposite was observed for vaterite. There was no clear relation observed in total CO2 uptake into hydrated cement paste with increasing temperature and pressure, possibly due to saturation of carbonation after 24 hours of reaction.

Summary: In this study, a new design of ATR-IR cell was proposed for in situ monitoring of fatty acid extraction from almonds under scCO2 conditions. The cell allows real-time measurement of the composition changes of the almonds at pressures up to 450 bar. The fast spectroscopic tracking of extracted components enables easy optimization of scCO2 conditions.

Summary: High-pressure pre-treatment and supercritical carbon dioxide (ScCO2) extraction were used to obtain the lipophilic fraction from a microalga Tetradesmus obliquus. The pre-treatment significantly increased the extraction yield and altered the chemical composition of the extracts. Furthermore, ScCO2 extraction reduced the microbial population in the biomass.

Summary: In this study, the compatibility and long-term integrity of candidate structural materials in high-temperature and high-pressure SCO2 were tested. The results showed that the corrosion kinetics of 316NG and 800H followed a near-cubic law. After 3000 hours of exposure, all oxide layers were continuous, compact, and protective. In the case of carburization, dark spots and enrichment of trace elements were observed.

Summary: Supercritical fluid chromatography (SFC) is often coupled with electrospray ionization mass spectrometry (ESIMS) for analyte detection. The ionization mechanism in SFC/ESI-MS is different from liquid chromatography due to the use of CO2 as a mobile phase. The formation of methoxylcarbonic acid contributes to ion generation and detection in positive-ion mode, but interferes with ionization in negative-ion mode.

Summary: This study investigated the high-temperature polymorphic conversion of carbamazepine (CBZ) in a high-density supercritical CO2 medium, revealing that the scCO(2) phase contains only one CBZ conformer when in equilibrium with CBZ melt - SCF solution. It was proven that pure CBZ polymorph I can be obtained through crystallization from CBZ solution in scCO(2).

Summary: This study aims to experimentally measure the solubility of teriflunomide in supercritical carbon dioxide and describe the solubility using mathematical models. The results show that the solubility of teriflunomide is strongly dependent on pressure and has a complex relationship with temperature. The model proposed by Sodeifian et al. achieves the lowest deviation.
