Praseodymium (Pr) and neodymium (Nd) were selected as representatives of LREE, while europium (Eu), dysprosium (Dy), and erbium (Er) represented HREE. The extraction process was carried out using hydrophobic deep eutectic solvents (HDES) composed of stearic acid as the hydrogen bond donor (HBD) and menthol, thymol, tetraoctylammonium bromide, and trioctylphosphine oxide as the hydrogen bond acceptors (HBAs). The hydrophobicity, solid-liquid equilibria (SLE), σ-surface, σ-profile and chemical bonding of the solvents were studied using Conductor-like Screening Model for Real Solvents (COSMO-RS). The analysis of the σ-surfaces and σ-potentials revealed that the HDES are predominantly composed of nonpolar regions, accompanied by smaller peaks corresponding to hydrogen bond donor and acceptor sites. Prepared HDES exhibit density ranging from 861 to 903 kg/m³ and viscosities ranging from 0.35 to 0.34 Pa.s. Finally, the study investigated the impact of hydrophobicity on the REEs extraction performance and discussed the removal mechanisms in all the different solvents. The effect of the lanthanide contradiction was also investigated. Among the various HDES developed, TOPO:stearic acid (x₁ = 0.59) exhibited the best extraction efficiency with an overall removal of 72.23 ± 1.29% from 0.01 M REEs solution.</div></div>","PeriodicalId":100794,"journal":{"name":"Journal of Ionic Liquids","volume":"5 2","pages":"Article 100176"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145095288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence of sulfur-containing compounds in fuel oil is an overwhelming problem in the petrochemical industries due to regulations for environmental protection. The emitted toxic gases from the combustion of fossil fuels result in air contamination that can damage the human respiratory system, cause acid rain, and negatively affect refinery equipment. Therefore, fuel desulfurization becomes necessary to remove sulfur and its derivatives from fuel oil. Recently, ionic liquids (ILs) have been identified as good candidates for many industrial applications. They are widely known for their potential as designer solvents due to fascinating properties such as low volatility, high tunability, and high thermal stability. However, their general environmental impact varies significantly depending on their specific chemical compositions with some ILs exhibiting toxicity or poor biodegradability. The present study comprehensively reviews the recent achievements and applications of ILs in fuel oil desulfurization, addressing the mechanisms of the conversion process. The practicality and reusability of ILs for fuel oil desulfurization have been reported, and finally, the conclusion and future research prospects in this exciting area have been suggested.

However, the low solubility and slow kinetics of the DESs hinder their application in the extraction of metals from different sources. In this paper, two approaches for the recovery of cobalt (Co) and nickel-cobalt (Ni-Co) alloys from Nickel–Metal Hydride (Ni-MH) spent batteries using the DES as a leaching agent have been studied. From Ultraviolet–visible spectroscopy (UV–Vis), Cyclic Voltammetry (CV), and Inductively Coupled Plasma–Optical Emission Spectroscopy (ICP-OES) measurements, a faster approach to selectively extract cobalt from the eutectic mixture has been proven. Electrochemical behavior and electrodeposition of Ni and Co metals from the cathodic powder of spent Ni-MH batteries dissolved in the DES solution have also been performed by electrochemical techniques such as CV and chronoamperometry (CA). Results from electrochemical techniques have verified the extractability of Ni and Co from DES liquor. Voltametric traces also offered a simple way to determine qualitatively and quantitatively the concentration of metallic ions dissolved in the DES. By analyzing the potentiostatic current density transients recorded from the DES liquor, it was possible to explain the mechanisms and kinetics of formation of the recovered materials on the glassy carbon electrode surface using a model composed of a 3D nucleation and diffusion-controlled growth of bimetallic nuclei on the growing surfaces. Scanning Electron Microscopy (SEM) images of the glassy carbon electrode (GCE), after the potentiostatic electrodeposition, showed evidence of the formation of Ni and Co nuclei distributed all over the substrate surface.

Due to the overwhelming costs and flight time associated with launching supplies to extraterrestrial bodies, the sustainability of these astronaut colonies will rely on readily available feedstocks and energy-efficient production methods on the surface. The Martian environment contains numerous elements, mostly in the form of compounds within the regolith and local atmosphere, that could be used for producing metallic components. Ionic liquids (ILs) have been demonstrated as a low-temperature regolith and meteorite metal harvesting system by NASA’s Marshall Space Flight Center (MSFC). Additionally, the Bosch process has shown success as an oxygen (O&lt;sub&gt;2&lt;/sub&gt;) generation system possessing theoretical 100 % hydrogen (H&lt;sub&gt;2&lt;/sub&gt;) recovery, producing a solid carbon (C) byproduct. Studies on the use of IL-metals and Bosch C in ferrous castings have been conducted in recent years with immense success. This study further investigates an alloy composition based on IL harvested iron (IL-Fe) and Bosch C to produce a novel IL-steel alloy for additive manufacturing (AM) by combining the products of IL’s and Bosch C into a printable steel composition. The IL-steel powder was produced using commercially available elements and the addition of Bosch C from the rotary kiln C-formation reactor (C-FR) at MSFC’s Environmental Controls and Life Support Systems (ECLSS) branch. Raw materials were alloyed into steel ingots and atomized to a targeted powder size distribution of 15-45 μm. A series of progressively refined build parameters (laser power and exposure time) were used to produce cubic samples that were investigated to determine baseline laser powder bed fusion (PBF-LB) settings for printing with IL-steel. Bulk density was used as the initial filtering mechanisms, with Vickers microhardness and microstructural investigations being conducted on the final matrix of samples. Moving forward, IL and Bosch C production will need further refinement to limit elements that could negatively affect printed products, and production volumes will need to be increased beyond laboratory scales. Future investigations with IL-Steel will require characterization of the powder’s flowability, laser interaction, and printability in reduced gravity and extraterrestrial atmospheric conditions. Additionally, further mechanical characterization, i.e. tension, fatigue, etc., will be required to determine the potential use cases of IL-Steel on Mars and solidify its applicability.
