Two liquid states of matter: A new dynamic line on a phase diagram

, 2011
It is generally agreed that the supercritical region of a liquid consists of one single state (supercritical fluid). On the other hand, we show here that liquids in this region exist in two qualitatively different states: "rigid" and "non-rigid" liquid ...

Dynamical and thermodynamic crossovers in the supercritical region of a holographic superfluid model

European Physical Journal C: Particles and Fields
Many physical systems, including classical fluids, present in their phase diagram the competition between two phases that are separated by a line of first-order phase transitions which terminates at a so-called critical point.

Utilizing supercritical geothermal systems: a review of past ventures and ongoing research activities

Geothermal Energy, 2017
Supercritical geothermal systems are very high-temperature geothermal systems that are located at depths near or below the brittle–ductile transition zone in the crust where the reservoir fluid is assumed to be in the supercritical state, that is for ...

The subgrid-scale scalar variance under supercritical pressure conditions [PDF]

, 2011
To model the subgrid-scale (SGS) scalar variance under supercritical-pressure conditions, an equation is first derived for it. This equation is considerably more complex than its equivalent for atmospheric-pressure conditions.

Deoxygenation of Fatty Acids in Supercritical Hexane over Bimetallic Catalyst for Biodiesel Production

Chemical Engineering Transactions, 2019
Deoxygenation process is considered to be a promising way to produce the second generation of biodiesel. The main drawbacks of this process are high temperature, high reaction time and the necessity in hydrogen presence aimed at the formation of ...

A critical point for bifurcation cascades and featureless turbulence

, 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.

Improvement of the dissolution of the antineoplastic drug regorafenib through impregnation into pullulan polysaccharide using supercritical fluid technology: Optimization of the process

Journal of CO2 Utilization
Regorafenib is administered orally for the treatment of metastatic colorectal cancer. However, its limited water solubility hinders its clinical efficacy. This study explores the impregnation of regorafenib monohydrate (REG MH) into pullulan (PULL) using

Spherically averaged versus angle-dependent interactions in quadrupolar fluids

, 2008
Employing simplified models in computer simulation is on the one hand often enforced by computer time limitations but on the other hand it offers insights into the molecular properties determining a given physical phenomenon.

Method for growth of crystals by pressure reduction of supercritical or subcritical solution [PDF]

, 1985
Crystals of high morphological quality are grown by dissolution of a substance to be grown into the crystal in a suitable solvent under high pressure, and by subsequent slow, time-controlled reduction of the pressure of the resulting solution. During the
