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

Supercritical Carbon Dioxie; An Efficient Solvent for Herbal Extraction
Journal of Medicinal Plants, 2017 Supercritical fluid extraction (SFE) is an alternative to liquid extraction using solvents. Supercritical fluids can have solvating powers similar to organic solvents, but with higher diffusivities, lower viscosity, and lower surface tension.

On Refinement of Several Physical Notions and Solution of the Problem of Fluids for Supercritical States [PDF]
arXiv, 2009 To solve the ancient problem of fluids, i.e., of states in which there is no difference between gas and liquid (the so-called supercritical states), it is necessary to abandon several "rules of the game", which are customary to physicists and to refine them by using rigorous mathematical theorems.

Comments on Van der Waals supercritical fluid: Exact formulas for special lines [J. Chem. Phys. 135, 084503 (2011)] [PDF]
arXiv, 2018 The equations for Widom lines for the supercritical van der Waals fluid were considered in the paper J. Chem. Phys. 135, 084503 (2011). But the equations for the speed of sound and its special Widom line were incorrect. The correct equations are obtained.
