Separation of Methylcyclohexane-Toluene Mixture Using Imidazolium Ionic Liquids

Chemical Engineering Transactions, 2022
This study aimed to design a process for methylcyclohexane-toluene mixture separation. For the separation of a binary mixture containing 10 mole % of toluene, two imidazolium ionic liquids (ILs) were tested, namely 1-hexyl-3-methylimidazolium ...

Vacuum Interaction of Crossed Cosmic Strings

Universe, 2021
In this paper, we consider the vacuum energy of a scalar field in the spacetime of two non-parallel cosmic strings. To this end, we obtain metrics for orthogonal straight cosmic strings and for slightly nonparallel strings.

Harvesting entanglement by non-identical detectors with different energy gaps

Journal of High Energy Physics, 2022
It has been shown that the vacuum state of a free quantum field is entangled and such vacuum entanglement can be harvested by a pair of initially uncorrelated detectors interacting locally with the vacuum field for a finite time.
