Thermodynamics of gas–liquid colloidal equilibrium states: hetero-phase fluctuations [PDF]

open access: yes, 2019
Following on from two previous JETC (Joint European Thermodynamics Conference) presentations, we present a preliminary report of further advances towards the thermodynamic description of critical behavior and a supercritical gas-liquid coexistence with a

Supercritical fluid technology for solubilization of poorly water soluble drugs via micro- and naonosized particle generation

open access: yesADMET and DMPK, 2020
Approximately two-third of the compounds in the pharmaceutical industry were developed through combinatorial chemistry and high throughput screening of particulate solids.

Application of New Supercritical Extraction Technology in Extraction and Separation of Effective Components of Traditional Chinese Medicine [PDF]

open access: yesMATEC Web of Conferences, 2021
Supercritical CO2 extraction technology uses supercritical CO2 fluid as extractant to extract and separate effective components from plants from liquid or solid. At present, CO2 is widely used in supercritical fluid, with a critical temperature of 31.265

Using Static Culture Method to Increase the Production of Acetobacter Xylinum Bacterial Cellulose

open access: yesJournal of Natural Fibers
Bacterial cellulose is a natural polymer, usually produced through synthetic (chemically defined) or natural media. However, the current methods of bacterial cellulose production are not ideal because of their low productivity and large number of ...

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

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.

Electrodeposition from supercritical fluids

open access: yes, 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

Regeneration of Modified Bentonite Loaded with Phenol Using Supercritical Fluids

open access: yesAdsorption Science & Technology, 2004
The desorption of phenol from organically modified bentonite (ODTMA–bentonite) using supercritical fluids was studied. Parameters such as pressure, temperature, supercritical fluid flow rate and co-solvent (entrainer) concentration were investigated. The

A critical point for bifurcation cascades and featureless turbulence

open access: yes, 2019
In this Letter we show that a bifurcation cascade and fully sustained turbulence can share the phase space of a fluid flow system, resulting in the presence of competing stable attractors.

A regenerative supercritical-subcritical dual-loop organic Rankine cycle system for energy recovery from the waste heat of internal combustion engines [PDF]

open access: yes, 2017
Organic Rankine cycle (ORC) system is considered as a promising technology for energy recovery from the waste heat rejected by internal combustion (IC) engines.
