The research results were published in《RSC Advances》 in 2022.Product Details of 65039-09-0 The article conveys some information:

As the predominant precursor for high-performance carbon fiber manufacturing, the fabrication of polyacrylonitrile (PAN)-based composite fibers attracts great interest. Ionic liquids (ILs) have recently been investigated for melt-spinning of ultrafine PAN fibers. The plasticizing properties of ILs are significantly affected by the structure of ILs and can be influenced by electronegativity, steric effects, etc. Herein, we report a facile strategy to control the elasticity of the PAN/ILs fibers by tuning the anion structure of ILs. Particularly, the ILs containing nitrile-rich groups exhibited enhanced plasticizing effect and nucleating ability on dissolving PAN components, achieving highly stretchable PAN/ILs fibers.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

The article was appeared in 《Journal of Luminescence》. They have made some progress in their research.Application In Synthesis of 2-(1H-Benzo[d]imidazol-2-yl)aniline The article mentions the following:

Excited-state intramol. proton transfer (ESIPT) reactions and electronic properties of the NH-type hydrogen bonding mols. (APBI, APBO, APBT, and APIP) and their derivatives have been theor. investigated. For the different heteroatoms at the same position, the oxygen (APBO) and sulfur (APBT) bring weak intra-HB leading to only normal emission while the nitrogen (APBI) makes moderatly strong intra-HB in APBI giving dual emission. For the nitrogen heteroatoms at the different positions, the tertiary nitrogen in APIP greatly enhances intramol. charge transfer (ICT) resulting in a tautomer emission maximum (driven by ESIPT) at much longer wavelength compared to that of APBI with secondary nitrogen. Moreover, the introduction of a tosyl (Ts) into one of amino protons of the NH-type mols. yielding Ts-substituted derivatives can ensure their ESIPT providing a single tautomer emission. Furthermore, the addition of a moderatly strong electron withdrawing group (cyano) in tosylaminophenyl causes a slight blue-shift of the tautomer emission maximum while the addition of a moderatly strong electron donating group (amino) makes a noticeable red-shift of the emission maximum compared to their parents. Among the designed derivatives, APIP-tosyl-NH2 photoexcited at around 360 nm exhibits the longest wavelength of tautomer emission in near IR region caused by strong ICT leading to large Stokes shift that can avoid self-reabsorption which is an important character for fluorescent probes.2-(1H-Benzo[d]imidazol-2-yl)aniline (cas: 5805-39-0) were involved in the experimental procedure.

1-Ethyl-3-methyl-1H-imidazol-3-ium chloride(cas: 65039-09-0) is an imidazolium chloride ionic liquid that can be used as:a solvent as well as catalyst for the depolymerization of oak wood lignin; a solvent in the hydrolysis of hemicellulose (xylan) to xylose using Brønsted acid catalysts.Safety of 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride

Safety of 1-Ethyl-3-methyl-1H-imidazol-3-ium chlorideIn 2022, Rasoolzadeh, Ali;Bakhtyari, Ali;Sedghamiz, Mohammad Reza;Javanmardi, Jafar;Nasrifar, Khashayar;Mohammadi, Amir H. published 《A thermodynamic framework for determination of gas hydrate stability conditions and water activity in ionic liquid aqueous solution》. 《Journal of Molecular Liquids》published the findings. The article contains the following contents:

The formation of gas hydrates in pipelines and plugging of the gas flow path are a major cause of operating expenses, safety issues, pressure drop, and fatal accidents. Therefore, the inhibition of gas hydrate formation is of paramount importance. The utilization of a new class of inhibitors such as ionic liquids (ILs) is currently of great interest. In this regard, adjusting water activity in the inhibitor blend (water + IL) is a vital factor. Several models have been developed to calculate the activity of water in the presence of IL(s). The major disadvantage of these models is their correlative basis. This study aimed to propose a rigorous predictive model for the calculation of water activity in the presence of IL(s), which would then be applied in the prediction of the gas hydrate stability conditions. The model is made up of a mol. term (the short-range interactions from Free-Volume-Flory-Huggins (FVFH) activity model) as well as a contribution from ionic interactions as a result of IL(s) dissociation in water (the long-range electrostatic interactions from the extended Debye-Huckel (EDH) model). The overall absolute temperature deviation and the average absolute relative deviation percent in the calculated gas (methane and carbon dioxide) hydrate dissociation temperatures for the whole databank (500 data points including 37 ILs) were found to be 0.61 K and 0.22%, resp. This proves the superiority of the model over the previous correlative-basis ones. Finally, it is concluded that the higher temperature, the higher the IL(s) concentration, and the lower IL(s) mol. weight(s) result in larger model deviations.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

Safety of 1-Ethyl-3-methyl-1H-imidazol-3-ium chlorideIn 2022, Li, Zhanyu;Lv, Wenrong;Wu, Gaohong;Li, Xiaoxiao;Wang, Xiaoxu;Zhang, Wenming published 《Multi-type cubic Co_mX_n (X = O, S, Se) induced by zeolitic imidazolate framework (ZIF) as cathode materials for aluminum battery》. 《Chemical Engineering Journal (Amsterdam, Netherlands)》published the findings. The article contains the following contents:

Since the energy storage mechanism of metal oxides, sulfides and selenides as cathode materials for aluminum ion batteries (AIBs) is still unclear, we successfully prepared multi-type cubic Co_mX_n (X = O, S, Se) by ZIF induction to study and analyze the energy storage mechanism. Through ex-situ XRD and XPS characterization, it is found that Co₃O₄ and Co₃S₄ only cause the valence change of Co element for energy storage due to the insertion and extraction of Al³⁺, while in CoSe₂, not only Co but also Se element is involved in the redox reaction. Besides, CoSe₂ exhibits higher operating voltage and excellent discharge capacity compared to Co₃O₄ and Co₃S₄. At 100 mA g^-1, CoSe₂ exhibits two operating voltages at 0.8 V and 1.8 V, and its first discharge capacity is 785.6 mAh g^-1, while the discharge voltage of Co₃O₄ and Co₃S₄ is only about 0.6 V, and the discharge capacities are 388.3 mAh g^-1 and 579.7 mAh g^-1, resp. After 500 cycles, the discharge capacities of CoSe₂ are maintained at 148.9 mAh g-1 at 500 mA g^-1. In addition, DFT proves that, compared with Co₃O₄ and Co₃S₄, CoSe₂ is more conducive to the surface adsorption and diffusion of AlCl-4, which lays a key foundation for the research on the cathode materials of aluminum batteries. To complete the study, the researchers used 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .

The authors were Lv, Sichao;Chen, Tao;Wang, Tingting;Li, Yang;Gao, Xinlei, and the article was included in《Journal of Dispersion Science and Technology》. The author mentioned the following in the article:

The purpose of this paper is to study the friction-reducing properties of 23 N-containing heterocyclic ionic liquid additives in polyethylene glycol 400 (PEG-400) or DMSO (DMSO). Based on the theory of quant. structure tribo-ability relationship (QSTR), the quantum chem. parameters of 23 N-containing heterocyclic ionic liquid mols. were calculated by d. functional theory, and the friction-reducing properties of the ionic liquid additives in PEG-400 or DMSO were studied by multiple linear regression. The results show that QSTR models with excellent stability and strong prediction abilities were obtained for both polar liquids studied. Heat capacity of the ionic liquid is the main quantum chem. parameter affecting its friction-reducing performance. The friction-reducing performance of the selected ionic liquid additive in DMSO is better than that in PEG-400. A friction-reducing mechanism is also discussed. To complete the study, the researchers used 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .

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. The experimental procedure involved many compounds, such as 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .

Application In Synthesis of 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride《Halide anions engineered ionic liquids passivation layer for highly stable inverted perovskite solar cells》 was published in 2022. 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. The experimental procedure involved many compounds, such as 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .
