Ab initio intermolecular interactions mediate thermochemically real-fluid effects that affect system reactivity [PDF]

open access: yesarXiv
The properties of supercritical fluids are dictated by intermolecular interactions that involve two or more molecules. Such intermolecular interactions were described via intermolecular potentials in historical supercritical combustion modeling studies, but have been treated empirically and with no consideration of radical interactions or multi-body ...

A Review of the Use of Chemical Stabilisation Methods for Lithium‐Ion Batteries

open access: yesBattery Energy, EarlyView.
The review reveals that while chemical stabilisation techniques for recycling EOL LIBs are widely used, many studies overlook safety risks, focusing on quick, low‐cost methods. Only a few studies address the associated hazards, highlighting the need for safer, well‐understood stabilisation processes in battery recycling. ABSTRACT The increasing amounts

Ultra‐high‐performance supercritical fluid chromatography‐mass spectrometry for the analysis of organic contaminants in sediments

open access: yesJournal of Separation Science, Volume 46, Issue 1, January 2023., 2023
A nontarget screening method was developed based on D‐optimal designs for ultra‐high performance supercritical fluid chromatography with positive and negative electrospray ionization mode mass spectrometry. A mixture of organic contaminants such as pesticides, steroids, surfactants, phenolic and fatty acids, and polycyclic aromatic hydrocarbon ...

Physics of rapidly expanding supercritical solutions: A first approach [PDF]

open access: yesarXiv, 1999
We consider the case when a supercritical fluid emerges at sonic speed from a small orifice in a high pressure chamber. The subsequent expansion causes a pressure drop and the fluid then enters a regime where its equation of state in $P-V$ space becomes concave towards the origin. This is the signal for an expansion shock to occur in a non-ideal fluid.

Electrodeposition from supercritical fluids

open access: yesPhysical Chemistry Chemical Physics, 2014
Recent studies have shown that it is possible to electrodeposit a range of materials, such as Cu, Ag and Ge, from various supercritical fluids, including hydrofluorocarbons and mixtures of CO2 with suitable co-solvents. In this perspective we discuss the relatively new field of electrodeposition from supercritical fluids.

Supercritical fluids in separation and purification: A review

open access: yesMaterials Science for Energy Technologies, 2019
The properties of the supercritical fluid near the critical point can be changed by varying the pressure and temperature, allowing selective and faster extraction.
