Hydrophobic deep eutectic solvents: Current progress and future directions
Mohamad Hamdi Zainal-Abidin,Maan Hayyan,Won Fen Wong 한국공업화학회 2021 Journal of Industrial and Engineering Chemistry Vol.97 No.-
Deep eutectic solvents (DESs) are novel ‘green’ solvents that have recently gained considerable interestfrom the scientific community in different sectors. They are considered biocompatible, chemically stable,biodegradable, low volatile, and also non-flammable. The physicochemical properties of DESs are highlytunable and can be customized to meet the needs of a particular mission. A new category of DESs, referredto as hydrophobic DESs (HDESs), is considered to be a promising subclass of traditional DESs to resolvethe issue of instability their contact with water. The HDESs have been extensively studied for the isolationand extraction of volatile fatty acids, heavy metals, and bioactive compounds from aqueous solutions. However, the HDESs remain briefly addressed in the literature. This review report therefore summarizesthe ground-breaking and innovative efforts of the HDESs, including their properties and applications,which have so far been lacking in scientific literature. In addition, the prospects of HDES application inmedicine (e.g., control of COVID-19 pandemic) are also highlighted. To end, remarks and possibleperspectives are highlighted and concluded in detail.

Greening industrial applications with magnetic-based deep eutectic solvents: A promising future
Mohamad Hamdi Zainal-Abidin,Maan Hayyan,Juan Matmin,Abdo Mohammed Al-Fakih,Naharullah Jamaluddin,Wan M. Asyraf Wan Mahmood,Roswanira Abdul Wahab,Faizuan Abdullah 한국공업화학회 2023 Journal of Industrial and Engineering Chemistry Vol.124 No.-
The field of green technology is evolving rapidly to address new industrial challenges, and deep eutecticsolvents (DESs) have emerged as a potential alternative to traditional organic compounds and ionic liquids. Among their main classes, magnetic DESs (MagDESs) have gained significant attention due to theirunique magnetic properties resulting from the presence of magnetic ions in the solvent. The unique magneticproperties of MagDESs, combined with their stability and compatibility, make them suitable for variousapplications, including magnetic separation and purification. The ease of separation of MagDESsfrom their respective mixtures via the application of an external magnetic field distinguishes them asa desirable solution, enabling quick extraction and easy collection without centrifugation. Moreover,DESs can serve to endow magnetic materials with new functionalities for a wide range of applications. Utilizing DESs enables the functionalization of magnetic materials without the use of volatile organic solventsor extended processing periods. MagDESs are expected to be used in the extraction of various compounds,but there are some limitations that must be considered, such as compatibility issues, recoverydifficulty, and also long-term stability and sustainability of MagDESs in different environments and applications. Further research and development are necessary to fully understand and optimize the benefitsand limitations of MagDESs.
