Dynamic transition in supercritical iron [PDF]
arXiv, 2014 Recent advance in understanding the supercritical state posits the existence of a new line above the critical point separating two physically distinct states of matter: rigid liquid and non-rigid gas-like fluid. The location of this line, the Frenkel line, remains unknown for important real systems. Here, we map the Frenkel line on the phase diagram of

ChemistryOpen, EarlyView.We demonstrated the potential of formic acid for efficient hydrogen storage and regeneration through CO₂ reduction followed by dehydrogenation. Using Cp*Ir catalysts with an amino‐substituted bipyridine ligand, we achieved a 96 % yield of formic acid with a formate concentration of 0.81 mol/L under supercritical conditions, followed by dehydrogenation ...

Analysis of Enantiomers in Products of Food Interest
Molecules, 2019 The separation of enantiomers has been started in the past and continues to be a topic of great interest in various fields of research, mainly because these compounds could be involved in biological processes such as, for example, those related to human ...

Ab initio intermolecular interactions mediate thermochemically real-fluid effects that affect system reactivity [PDF]
arXivThe properties of supercritical fluids are dictated by intermolecular interactions that involve two or more molecules. Such intermolecular interactions were described via intermolecular potentials in historical supercritical combustion modeling studies, but have been treated empirically and with no consideration of radical interactions or multi-body ...

Local structure of supercritical matter [PDF]
arXiv, 2014 The supercritical state is currently viewed as uniform on the pressure-temperature phase diagram. Supercritical fluids have the dynamic motions of a gas but are able to dissolve materials like a liquid. They have started to be deployed in many important industrial applications stimulating fundamental theoretical work and development of experimental ...

Phytochemical Analysis, EarlyView.ABSTRACT Introduction Terpenes, which are found in high concentrations in the essential oil fraction of the Cannabis sativa flower, have demonstrated potential in many therapeutic and industrial applications. Objectives This work reports on a method developed for quantifying 18 terpenes in C. sativa essential oil obtained through hydrodistillation. The

Superheated liquids for the extraction of solid residues from winemaking processes [PDF]
, 2003 Solid residues from winemaking process have been subjected to extraction with superheated water-ethanol mixtures. Identification and characterisation of the extracted compounds have been made by spectrophotometry, gas chromatography with either flame ...
