Valorization of Tomato Residues by Supercritical Fluid Extraction
Processes, 2021 Tomato processing leads to the production of considerable amounts of residues, mainly in the form of tomato skins, seeds and vascular tissues, which still contain bioactive molecules of interest for food, pharmaceutical and nutraceutical industries ...

Application of New Supercritical Extraction Technology in Extraction and Separation of Effective Components of Traditional Chinese Medicine [PDF]
MATEC Web of Conferences, 2021 Supercritical CO2 extraction technology uses supercritical CO2 fluid as extractant to extract and separate effective components from plants from liquid or solid. At present, CO2 is widely used in supercritical fluid, with a critical temperature of 31.265

Thermodynamic crossovers in supercritical fluids [PDF]
Proceedings of the National Academy of Sciences, 2024, 121(18):
e2400313121, 2023 Can liquid-like and gas-like states be distinguished beyond the critical point, where the liquid-gas phase transition no longer exists and conventionally only a single supercritical fluid phase is defined? Recent experiments and simulations report strong evidence of dynamical crossovers above the critical temperature and pressure.

Sub and Supercritical Decontamination of Oil-Based Drill Cuttings: A Review [PDF]
Environmental Energy and Economic Research, 2019 Drill mud is a fluid which is used in oil extraction industries in order to cool and lubricate the drill bit. Due to containing numerous toxic components, it is considered as a hazardous waste which must be treated before discharging to the environment ...

Double universality of the transition in the supercritical state [PDF]
Science Advances 8, eabq5183 (2022), 2022 Universality aids consistent understanding of physical properties. This includes understanding the states of matter where a theory predicts how a property of a phase (solid, liquid, gas) changes with temperature or pressure. Here, we show that the matter above the critical point has a remarkable double universality not limited by pressure and ...

Universal two-component dynamics in supercritical fluids [PDF]
The Journal of Physical Chemistry B 125(49), 13494-13501 (2021), 2021 Despite the technological importance of supercritical fluids, controversy remains about the details of their microscopic dynamics. In this work, we study four supercritical fluid systems -- water, Si, Te, and Lennard-Jones fluid -- \emph{via} classical molecular dynamics simulations.
