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.

The Application of Supercritical Fluid Extraction in Phenolic Compounds Isolation from Natural Plant Materials

open access: yesMolecules, 2018
The separation of phenolic compounds by supercritical fluid extraction has been widely studied throughout the last two decades. This is evidenced by a number of publications and articles. Supercritical fluid extraction (SFE) has become thus the effective

Crossover from gas-like to liquid-like molecular diffusion in a simple supercritical fluid [PDF]

open access: yesNature Communications
According to textbooks, no physical observable can be discerned allowing to distinguish a liquid from a gas beyond the critical point. Yet, several proposals have been put forward challenging this view and various transition boundaries between a gas-like

A Study on Generation and Feasibility of Supercritical Multi-Thermal Fluid

open access: yesEnergies, 2022
Supercritical multi-thermal fluid is an emerging and efficient heat carrier for thermal recovery of heavy oil, but the generation of supercritical multi-thermal fluid and its feasibility in thermal recovery are rarely discussed. In this paper, generation

Thermodynamic crossovers in supercritical fluids [PDF]

open access: yesProceedings of the National Academy of Sciences, 2024, 121(18): e2400313121, 2023
Can liquid-like and gas-like states be distinguished beyond the critical point, where the liquid-gas phase transition no longer exists and conventionally only a single supercritical fluid phase is defined? Recent experiments and simulations report strong evidence of dynamical crossovers above the critical temperature and pressure.

Double universality of the transition in the supercritical state [PDF]

open access: yesScience Advances 8, eabq5183 (2022), 2022
Universality aids consistent understanding of physical properties. This includes understanding the states of matter where a theory predicts how a property of a phase (solid, liquid, gas) changes with temperature or pressure. Here, we show that the matter above the critical point has a remarkable double universality not limited by pressure and ...

Universal two-component dynamics in supercritical fluids [PDF]

open access: yesThe Journal of Physical Chemistry B 125(49), 13494-13501 (2021), 2021
Despite the technological importance of supercritical fluids, controversy remains about the details of their microscopic dynamics. In this work, we study four supercritical fluid systems -- water, Si, Te, and Lennard-Jones fluid -- \emph{via} classical molecular dynamics simulations.
