Criticality-related fundamental bases for new generations of gas-liquid, liquid-liquid, and liquid (LE) extraction technologies [PDF]
arXiv, 2022 The report presents results that can be considered as the reference for innovative generations of Supercritical Fluids (SCF), Liquid-Liquid (LL), and Liquid (L) extraction technologies. They are related to implementations of Critical Phenomena Physics for such applications not considered so far.

Universality, scaling and collapse in supercritical fluids [PDF]
, 2019 The Supercritical Fluid (SCF) is known to exhibit salient dynamic and thermodynamic crossovers and inhomogeneous molecular distribution. But the question as to what basic physics underlies these microscopic and macroscopic anomalies remains open. Here, using an order parameter extracted by machine learning, the fraction of gas-like (or liquid-like ...

Modeling Heat Capacity of Supercritical Fluids: A Phonon Theory Approach [PDF]
arXiv, 2023 Recent research shows that liquids and dense supercritical fluids support high frequency shear waves. Here, we proposed a general heat capacity model of supercritical fluids using the latest theoretical findings (the liquid phonon theory). In this theory, heat capacity cv of supercritical fluids is only related to the infinite-frequency shear modulus ...

Supercritical fluid extraction: Application in the food industry [PDF]
Hemijska Industrija, 2002 Supercritical fluid extraction is an extraction process realized with supercritical fluids, which are at a temperature and pressure above their critical temperature and critical pressure.

A corresponding-state framework for the structural transition of supercritical fluids across the Widom delta [PDF]
J. Chem. Phys. 150, 154503 (2019), 2018 This work proposes a classification algorithm based on the radical Voronoi tessellation to define the Widom delta, supercritical gas-liquid coexistence region, of polyatomic molecules. In specific, we use a weighted mean-field classification method to classify a molecule into either gas-like or liquid-like.

ELECTROPHORESIS, Volume 43, Issue 23-24, Page 2334-2350, December 2022., 2022 Abstract The analytical requirements for food testing have increased significantly in recent years. On the one hand, because food fraud is becoming an ever‐greater challenge worldwide, and on the other hand because food safety is often difficult to monitor due to the far‐reaching trade chains.

Ferrocene derivatives with planar chirality and their enantioseparation by liquid‐phase techniques
ELECTROPHORESIS, Volume 44, Issue 1-2, Page 158-189, January 2023., 2023 Abstract In the last decade, planar chiral ferrocenes have attracted a growing interest in several fields, particularly in asymmetric catalysis, medicinal chemistry, chiroptical spectroscopy and electrochemistry. In this frame, the access to pure or enriched enantiomers of planar chiral ferrocenes has become essential, relying on the availability of ...

Soft-wall induced structure and dynamics of partially confined supercritical fluids [PDF]
J. Chem. Phys. 150, 111102 (2019), 2019 The interplay between the structure and dynamics of partially confined Lennard Jones (LJ) fluids, deep into the supercritical phase, is studied over a wide range of densities in the context of the Frenkel line (FL), which separates rigid liquidlike and non-rigid gaslike regimes in the phase diagram of the supercritical fluids.
