Supercritical fluid chromatography for vitamin and carotenoid analysis: an update covering 2011-2021
Journal of Chromatography Open, 2022 As it is known, the chromatographic separations of vitamins is not a trivial issue. The subtle heterogeneity among homologs belonging to the same group makes it difficult to perform their speciation.

Controlling Viscous Fingering Instabilities of Complex Fluids [PDF]
arXiv, 2022 The process of one fluid pushing another is universally common while involving complex interfacial instabilities. Particularly, occurring in a myriad of natural and industrial processes, wavy fingering patterns frequently emerge when a less viscous fluid pushes another more viscous one, such as water invading oil, in a porous medium. Such finger-shaped

Influence of pretreatments for extraction of lipids from yeast by using supercritical carbon dioxide and ethanol as cosolvent [PDF]
, 2011 Saccharomyces cerevisiae is one of the most studied and industrially exploited yeast. It is a non-oleaginous yeast whose lipids are mainly phospholipids.

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.

First Isolation of Enantiopure Perfluoroalkylated Sulfilimines and Sulfoximines
CHIMIA, 2014 Mono-, di- and trifluoromethyl sulfilimines and sulfoximines have been isolated for the first time in enantiopure form by separation of the racemate by supercritical fluid chromatography.

Thermodynamic behavior of supercritical matter [PDF]
Nature Communications 4, 2331 (2013), 2013 Since their discovery in 1822, supercritical fluids have been of enduring interest, and have started to be deployed in many important applications. Theoretical understanding of the supercritical state is lacking, and is seen to limit further industrial deployment.

State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials
Advanced Materials, EarlyView.Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.

Electrocarboxylation in supercritical CO2 and CO2-expanded liquids [PDF]
, 2008 In this study, the electrocarboxylation of benzyl chloride in pressurized CO2, or pressurized mixtures of dimethylformamide (DMF) and CO2, was investigated in order to synthesize phenylacetic acid.
