Разработка и регистрация лекарственных средств, 2022 Introduction. An increasing number of studies conducted in various countries in the field of biopharmacy convincingly show the differences in the physiological effects on the human body of stereoisomers of pharmaceutical substances. As a rule, one of the

A Study on Generation and Feasibility of Supercritical Multi-Thermal Fluid
Energies, 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]
Proceedings 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]
Science 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 ...

AIChE Journal, Volume 69, Issue 1, January 2023., 2023 Abstract Lignin‐rich stream from lignocellulosic ethanol production was converted into biocrude by continuous hydrothermal liquefaction (HTL) while hydrogen was produced by aqueous phase reforming (APR) of the HTL aqueous by‐product. The effects of Na2CO3 and NaOH were investigated both in terms of processability of the feedstock as well as yield and ...

Universal two-component dynamics in supercritical fluids [PDF]
The 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.

Lipidomics by Supercritical Fluid Chromatography [PDF]
International Journal of Molecular Sciences, 2015 This review enlightens the role of supercritical fluid chromatography (SFC) in the field of lipid analysis. SFC has been popular in the late 1980s and 1990s before almost disappearing due to the commercial success of liquid chromatography (LC). It is only 20 years later that a regain of interest appeared when new commercial instruments were introduced.

ELECTROPHORESIS, Volume 43, Issue 23-24, Page 2334-2350, December 2022., 2022 Abstract The analytical requirements for food testing have increased significantly in recent years. On the one hand, because food fraud is becoming an ever‐greater challenge worldwide, and on the other hand because food safety is often difficult to monitor due to the far‐reaching trade chains.
