The author mentioned the following in the article:

Pharmaceuticals and personal care products (PPCPs) are widely distributed in aquatic environments due to their large consumption and low biodegradability, causing ecol. risks. In this study, a porous thienyl cyclodextrin polymer (Th-CDP) with a sp. surface area of 730 m² g^-1 was synthesized in an ionic liquid system for the first time to remove PPCPs. The green and recyclable 1-ethyl-3-methylimidazolium chloride/ferric chloride ([EMIm]Cl/FeCl₃) ionic liquid was synthesized as a solvent and catalyst, superior to traditional toxic organic solvents and heterogeneous catalysts. In Th-CDP synthesis, thienyl cyclodextrin (ThCD) was synthesized, followed by polymerization with the three-dimensional crosslinking agent tri-Me orthoformate (Tmof) in [EMIm]Cl/FeCl₃ via the Friedel-Crafts alkylation reaction. Th-CDP shows excellent adsorption towards the studied PPCPs (diclofenac, ibuprofen, carbamazepine, and sulfamethoxazole) due to the rich pore structure. In particular, Th-CDP achieved 90% removal of hydrophobic diclofenac and ibuprofen in 5 min, and the rate constants were 16.7 and 10.5 times higher than those of activated carbon, resp. The adsorption capacity of Th-CDP is related to the mol. weight and pKa of the compound, and is about twice that of activated carbon. Th-CDP has more pronounced adsorption advantages over activated carbon for acidic compounds due to its pos. charge under neutral conditions. In addition, multiple mechanisms, including hydrophobic interaction caused by thiophene and cyclodextrin, electrostatic interaction, and heteroatom interaction (24.8% S content), enable Th-CDP to efficiently remove PPCPs. Moreover, Th-CDP has great application potential due to its excellent regenerability, anti-interference ability, and green synthesis process. The experimental procedure involved many compounds, such as 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .

X-ray Raman spectroscopy (XRS) is an emerging spectroscopic technique that utilizes inelastic scattering of hard X-rays to study X-ray absorption edges of low Z elements in bulk material. It was used to identify and quantify the amount of carbonyl bonds in a cathode sample, in order to track the redox reaction inside metal-organic batteries during the charge/discharge cycle. XRS was used to record the oxygen K-edge absorption spectra of organic polymer cathodes from different multivalent metal-organic batteries. The amount of carbonyl bond in each sample was determined by modeling the oxygen K-edge XRS spectra with the linear combination of two reference compounds that mimicked the fully charged and the fully discharged phases of the battery. To interpret exptl. XRS spectra, theor. calculations of oxygen K-edge absorption spectra based on d. functional theory were performed. Overall, a good agreement between the amount of carbonyl bond present during different stages of battery cycle, calculated from linear combination of standards, and the amount obtained from electrochem. characterization based on measured capacity was achieved. The electrochem. mechanism in all studied batteries was confirmed to be a reduction of double carbonyl bond and the intermediate anion was identified with the help of theor. calculations X-ray Raman spectroscopy of the oxygen K-edge was shown to be a viable characterization technique for accurate tracking of the redox reaction inside metal-organic batteries.

The article was appeared in 《Chemosphere》. They have made some progress in their research.SDS of cas: 65039-09-0 The article mentions the following:

In this study, waste peanut shells were sulfur-impregnated and used as acid catalysts in the presence of an ionic liquid for the conversion of fructose, glucose, and cellulose into 5-hydroxymethylfurfural, a useful chem. intermediate for biofuel production Effects of sulfur-doping duration (1 h and 5 h), solvent type and proportion, reaction temperature (130°C, 140°C, and 150°C), time (30-240 min), catalyst-to-substrate ratio (1-2.5 m/m), and agricultural residue (peanut shell, Canada wheat straw, water hyacinth, stalk, and reed) on HMF yields were investigated. Monophasic and biphasic ionic liquids such as [amim]Cl, [bmim]HSO₄, and [emim]Cl were employed in combination with choline chloride and DMSO to improve HMF yields. Results show that peanut shells subjected to prolonged sulfur impregnation produced higher HMF yields. At 130°C and 2 h, HMF yields from fructose and glucose reached 94.6% and 55.1%, resp. Higher reaction temperatures improved HMF yields and accelerated conversion rates for the sugar substrates. Moreover, HMF production from waste biomass namely, peanut shells, peanut stalk, Canadian wheat straw, reed, and water hyacinth were examined in sep. one-pot catalytic reactions. Overall, the study showed the effectiveness of sulfur-doped peanut shells as solid acid catalysts for the synthesis of HMF from various sources and the results may be used in designing large-scale production of furanic biofuel precursors from agricultural wastes.

Huang, Zheng;Song, Wei-Li;Liu, Yingjun;Wang, Wei;Wang, Mingyong;Ge, Jianbang;Jiao, Handong;Jiao, Shuqiang published 《Stable Quasi-Solid-State Aluminum Batteries》 in 2022. The article was appeared in 《Advanced Materials (Weinheim, Germany)》. They have made some progress in their research.HPLC of Formula: 65039-09-0 The article mentions the following:

Nonaqueous rechargeable aluminum batteries (RABs) of low cost and high safety are promising for next-generation energy storage. With the presence of ionic liquid (IL) electrolytes, their high moisture sensitivity and poor stability would lead to critical issues in liquid RABs, including undesirable gas production, irreversible activity loss, and an unstable electrode interface, undermining the operation stability. To address such issues, herein, a stable quasi-solid-state electrolyte is developed via encapsulating a small amount of an IL into a metal-organic framework, which not only protects the IL from moisture, but creates sufficient ionic transport network between the active materials and the electrolyte. Owing to the generated stable states at both pos.-electrode-electrolyte and neg.-electrode-electrolyte interfaces, the as-assembled quasi-solid-state Al-graphite batteries deliver specific capacity of ≈75 mA h g^-1 (with pos. electrode material loading ≈9 mg cm^-2, much higher than that in the conventional liquid systems). The batteries present a long-term cycling stability beyond 2000 cycles, with great stability even upon exposure to air within 2 h and under flame combustion tests. Such technol. opens a new platform of designing highly safe rechargeable Al batteries for stable energy storage.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

Functionalization of electrodes with clusters of hydrophobic mols. may improve the energy efficiency and selectivity of electrochem. separations by modulating the desolvation process occurring at the interface. Ionic liquids (ILs), which have a broad range of compositions and properties, are potential candidates for controlling the transport, desolvation, and adsorption of target ions at electrochem. interfaces. Herein, the authors report a joint exptl. and theor. study of the structure, stability, and selective adsorption properties of IL clusters 1-ethyl-3-methylimidazolium chloride [EMIM]_x[Cl]_x+1^– (x = 1-10) and demonstrate their ability to adsorb and sep. ions from the solution The structure and stability of the IL clusters are determined exptl. using high-mass-resolution electrospray ionization mass spectrometry, collision-induced dissociation, and neg.-ion photoelectron spectroscopy. The global optimization theory and ab initio mol. dynamics simulations provide mol.-level insights into the bonding and structural fluxionality of these species. Ion soft landing was used to selectively functionalize the surface of highly oriented pyrolytic graphite (HOPG) working electrodes with [EMIM]₁[Cl]₂^–, [EMIM]₃[Cl]₄^–, and [EMIM]₅[Cl]₆^– clusters. Kelvin probe microscopy provides insights into the relative stability of the clusters on HOPG and their effect on the work function of IL-functionalized electrodes. Cyclic voltammetry measurements reveal the irreversible adsorption of Fe(CN)₆^4-/3- anions during redox cycling, while electrochem. impedance spectroscopy indicates a substantial decrease in the electron transfer resistance of the IL-functionalized electrodes due to adsorption of Fe(CN)₆^4-/3-. Overall, the authors’ findings demonstrate that IL clusters with different sizes and stoichiometry may be used to increase the efficiency of electrochem. separations, opening new horizons in selective electrode functionalization.

The authors were Zhuang, Xinmeng;Chen, Xinfu;Xu, Lin;Liu, Shuainan;Wu, Yanjie;Shi, Zhichong;Zhou, Qingqing;Li, Bo;Yan, Haixia;Reiss, Peter;Song, Hongwei, and the article was included in《Journal of Colloid and Interface Science》. The author mentioned the following in the article:

Long-term stability remains a great challenge for metal halide perovskite solar cells (PSCs). The utilization of ionic liquids (ILs) is a promising strategy to solve the stability problem. However, few studies have focused on controlling the halide anions of ILs, in which different organic cations can modulate the m.p. of ILs and film crystal growth. Here, ILs with a 1-ethyl-3-methylimidazolium (EMIM+) cation and different halide anions (X = Cl, Br, and I) are employed in inverted PSCs. The results show that EMIMX can form a 1D passivation layer by the in situ growth technique and influence the surface morphol. of the perovskite film. These EMIMX-treated layers simultaneously suppress the surface defects and nonradiative energy losses and improve the hydrophobic properties. As a result, a power conversion efficiency (PCE) of 20.0% is obtained for the EMIMBr-modified PSCs compared to 18.06% for the control device. Moreover, the unencapsulated devices maintain more than 90% of their initial PCE over 3000 h under ambient air, which is among the best long-term stabilities reported for NiOx-based inverted PSCs. It also retains 74.2% and 49.5% of the initial PCE value after aging under harsher conditions, such as an 85 ± 5% relative humidity (RH) environment and at 85°C for 48 h, resp.

Product Details of 65039-09-0《Do certain imidazolium-based ionic liquid ion pairs/mordenite capture H₂S by conformational traps? An ONIOM-DFT study》 was published in 2022. The authors were Izquierdo, Rodolfo;Chacon, Gustavo;Cubillan, Nestor;Stassen, Hubert, and the article was included in《Microporous and Mesoporous Materials》. The author mentioned the following in the article:

We present detailed ONIOM(ωB97X-D:PM6) calculations for the formation mechanism of novel composites combining protonic mordenites (H-MOR) with various ionic liquids: 1,3-dimethyl-imidazolium chloride [MMIm]Cl, 1-ethyl-3-methyl-imidazolium chloride [EMIm]Cl; 1-methyl-3-propyl-imidazolium chloride [PMIm]Cl; 1-butyl-3-methyl-imidazolium chloride [BMIm]Cl, 1-(2-hydroxyethyl)-3-methyl-imidazolium chloride [HEMIm]Cl, 1,3-dimethyl-1,3,2-diazasilolium chloride [MMSiN]Cl, and 1,3-dimethyl-1,3-diphospholium chloride [MMPP]Cl. The most feasible [M]-MOR formation mechanism ([M]⁺ = [MMIm]⁺, [EMIm]⁺, [PMIm]⁺, [BMIm]⁺, [HEMIm]⁺, [MMSiN]⁺ [MMPP]⁺) involves an ion exchange at the T4O10 position favoring the isolation of a minimal number of [M]⁺ isomers (i.e., conformational traps). The interaction of these [M]-MOR composites with pollutant gases has afterward been evaluated. Among the studied systems, [EMIm]-MOR and [HEMIm]-MOR present electronic and steric conditions for potential applications in gas separation, capture, and storage (H₂ and H₂S). The H-MOR framework exhibits two structural conformers with the [HEMIm]+ cation in the confined space. Both, the MOR-T4O10-[HEMIm] and MOR-T4O10-[HEMIm]HB conformers, interconvert by a dynamic equilibrium with a transition state MOR-T4O10-TS1 acting as a conformational switch (Image 1-Image 2) that selectively recognizes and captures H₂S through a plier-like conformation.
