Fluidity and supercriticality of the QCD matter created in relativistic heavy ion collisions [PDF]

open access: yes, 2010
In this paper we discuss the fluidity of the hot and dense QCD matter created in ultrarelativistic heavy ion collisions in comparison with various other fluids, and in particular suggest its possible supercriticality.

Review of experimental research on supercritical and transcritical thermodynamic cycles designed for heat recovery application [PDF]

open access: yes, 2019
Supercritical operation is considered a main technique to achieve higher cycle efficiency in various thermodynamic systems. The present paper is a review of experimental investigations on supercritical operation considering both heat-to-upgraded heat and

Is there a third order phase transition for supercritical fluids? [PDF]

open access: yes, 2013
We prove that according to Molecular Dynamics (MD) simulations of liquid mixtures of Lennard-Jones (L-J) particles, there is no third order phase transition in the supercritical regime beyond Andrew's critical point.

Micronization processes by supercritical fluid technologies: a short review on process design (2008-2012) - doi: 10.4025/actascitechnol.v35i4.18819

open access: yesActa Scientiarum: Technology, 2013
Several micronization processes based on supercritical fluids have been developed. These processes can be classified according to the role of the supercritical fluid in the process: solvent, solute or co-solvent, and anti-solvent.

Shock formation in the collapse of a vapor nano-bubble [PDF]

open access: yes, 2014
In this paper a diffuse-interface model featuring phase change, transition to supercritical conditions, thermal conduction, compressibility effects and shock wave propagation is exploited to deal with the dynamics of a cavitation bubble. At variance with

Micro and nanosizing of Tamsulosin drug via supercritical CO2 antisolvent (SAS) process

open access: yesJournal of CO2 Utilization
Supercritical anti-solvent (SAS) method is a solvent-free approach where supercritical carbon dioxide (SC-CO2) is used as anti-solvent and one can control the output particle size without disturbing the nature of the particles.

Supercritical Fluid Geochemistry in Geothermal Systems

open access: yesGeofluids, 2019
Supercritical fluids exist in the roots of many active high-temperature geothermal systems. Utilization of such supercritical resources may multiply energy production from geothermal systems; yet, their occurrence, formation mechanism, and chemical ...
