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) .

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) .

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.

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 Petroleum Science & Engineering》. They have made some progress in their research.Safety of 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride The article mentions the following:

Naphthenic acids that are naturally carboxylic compounds contained in heavy crude oil are the main source of corrosion and blockage in a crude oil pipeline. The blockage is due to the formation of naphthenate deposits through a reaction of naphthenic acid with metal ions present in the crude oil. In the present study, model oil is used to evaluate the effect of water cut in the range of 10%-90%, brine pH in the range of 6-10, Ca²⁺ concentration in the range of 0.5%-2.5% and temperature in the range of 30 °C-60 °C towards naphthenate deposition with the aid of response surface methodol. NMR (NMR) and Fourier Transform IR (FTIR) were used to evaluate the structure of the naphthenic acids used. Results show that Ca²⁺ concentration contributes mostly to the naphthenate deposition, followed by brine pH, water cut and temperature Two math. models were developed to predict the final pH of the oil-brine system and the mass of precipitates with average relative errors (AREs) of 0.0328 and 0.0325 resp. The effects of two ionic liquids (ILs), 1-ethyl-3-methylimidazolium chloride (EMIM-Cl) and 1-butyl-3-methylimidazolium chloride (BMIM-Cl), on naphthenates precipitation, were also evaluated. Anal. showed that both ILs can reduce the amount of naphthenate deposited, with the BMIM-Cl showing better performance than the EMIM-Cl. And 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) was used in the research process.

Name: 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride《The mechanisms involved into the inhibitory effects of ionic liquids chemistry on adsorption performance of ciprofloxacin onto inorganic minerals》 was published in 2022. The authors were Chen, Jiuyan;Xu, Yalei;Zheng, Zhongqin;Wei, Qiqi;Farooq, Usman;Lu, Taotao;Chen, Weifeng;Qi, Zhichong, and the article was included in《Colloids and Surfaces, A: Physicochemical and Engineering Aspects》. The author mentioned the following in the article:

The ionic liquids (ILs) can influence the adsorption of antibiotics on minerals but there was ambiguity about mechanisms. Herein, we demonstrated the adsorption characteristics of ciprofloxacin (CIP) onto ferrihydrite and montmorillonite by various soluble ILs. Five imidazolium-based ILs with different alkyl chain lengths ([C₂mim]Cl, [C₄mim]Cl, [C₆mim]Cl) and counteranions ([C₄mim][TOS] and [C₄mim][PF₆]) were employed. The results validated that ILs could suppress CIP adsorption on both minerals due to the adsorption site competition between cations and CIP mols., steric hindrance induced by long alkyl chains of ILs, and electrostatic interaction. Interestingly, the adsorption-inhibition effects of ILs were almost unchanged with the lengthening alkyl chain for ferrihydrite, which were ascribed to the comparable adsorption capacities of the three ILs on ferrihydrite. Whereas, the effects of ILs on CIP adsorption onto montmorillonite followed the order of [C₆mim]Cl > [C₄mim]Cl > [C₂mim]Cl owing to the adsorption site competition and steric hindrance effects on the ILs increased with the lengthening alkyl chain. Furthermore, the inhibitory effects of ILs on CIP adsorption onto both studied minerals were also dependent on the counteranions (kept the same cation ([C₄mim]+)) and in the following order of [C₄mim][PF₆] > [C₄mim][TOS] > [C₄mim]Cl, which was mainly ascribed to the differences of anions in the ion sizes and the binding affinities to minerals. Addnl., the extent of the inhibitory impact of [C₄mim][TOS] on CIP adsorption onto ferrihydrite declined with increasing solution pH from 5.0 to 9.0, which was attributed to the amounts of adsorbed [TOS]^– declined with increasing pH. Contrarily, for montmorillonite, the extent increased with increasing pH, owing to increase in adsorption site competition and steric effect at higher pH conditions. Our findings emphasize the significance of emerging contaminants in understanding the antibiotic environmental behavior in eco-environmental systems. The experimental procedure involved many compounds, such as 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .

The author mentioned the following in the article:

Bioinspired electronics have shown great potential in the field of artificial intelligence and brain-like science. Low energy consumption and multifunction are key factors for its application. Here, multisensory artificial synapse and neural networks based on electrolyte-gated vertical organic field-effect transistors (VOFETs) are first developed. The channel length of the organic transistor is scaled down to 30 nm through crosslinking strategy. Owing to the short channel length and extremely large capacitance of the elec. double layer formed at the electrolyte-channel interface, the min. power consumption of one synaptic event is 0.06 fJ, which is significantly lower than that required by biol. synapses (1-10 fJ). Moreover, the artificial synapse can be trained to learn and memory images in a 5 x 5 synapse array and emulate the human brain′s spatiotemporal information processing and sound azimuth detection. Finally, the artificial tongue is designed using the synaptic transistor that can discriminate acidity. Overall, this study provides new insights into realizing energy-efficient artificial synapses and mimicking biol. sensory systems. To complete the study, the researchers used 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .

The research results were published in《Chemical Engineering Journal (Amsterdam, Netherlands)》 in 2022.Related Products of 65039-09-0 The article conveys some information:

A multivalent aluminum metal anode (AMA) can deliver high specific/volumetric capacities of 2,980 mA h g^-1/8,040 mA h cm^-3 in an ionic liquid-AlCl₃ electrolyte system. However, the large concentration overpotential of AMA induced by its distinctive anion-mediated aluminum metal redox mechanism causes poor rate capabilities and insufficient round-trip efficiencies, limiting its application in rechargeable aluminum batteries (RABs). In this paper, we report a novel strategy of using a carbonaceous catalytic host electrode for high-performance AMA. The targeted carbon electrode should have a high active surface area, strong interaction with ionic charge carriers, well-developed electronic pathways, and macroporous internal structures to accommodate incessantly deposited metals. In this regard, a 3D-structured carbon nanotube forest (CNT-F) was fabricated from waste polyolefins by a simple pyrolysis process as an optimal candidate for the catalytic host electrode. The waste-induced pyrolytic CNT-Fs (WP-CNT-F) had large open surface areas covered with multitudinous intrinsic carbon defects, on which uniform aluminum reduction reactions occurred concurrently, leading to significantly lower concentration overpotentials. In addition, the WP-CNT-Fs exhibited high coulombic efficiencies of 99.4-99.8% over a wide range of current densities (0.5-4.0 mA cm^-2) and great cycling stabilities over 1,000 cycles. The superior electrochem. performances of the WP-CNT-F-based AMA were demonstrated in the RAB full cells with a com. graphite cathode, affording a high specific energy and a high power d. of ∼132.2 W h kg^-1electrode and 10,230 W kg^-1electrode, resp., along with outstanding cycling stabilities over 2,500 cycles.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

The author mentioned the following in the article:

Rechargeable aluminum-ion batteries (AIBs) are considered to be promising alternatives to current lithium-ion batteries (LIBs), since they can have the advantages of low cost with high energy-to-price ratios. Unlike in LIBs, the charge storage mechanism in AIBs involving different ionic species is far more complicated and remains largely unexplored, which impedes further screening and optimization of cathode materials that can reversibly accommodate aluminum-based (complex) charge carriers with boosted cell performance. Here, we report a comprehensive study of the battery chem. in metal selenide based cathodes in AIBs from an integrated chem. and phys. point of view. Various in situ and ex situ characterization techniques and theor. calculations reveal that both Cl^– and AlCl₄^– can act as charge carriers in FeSe₂ cathodes during the charge process, and the Al³⁺ can also be embedded into the host upon the discharge process. Furthermore, using in situ magnetometry, the spin-polarized surface capacitance is observed in AIBs for the first time, which proves that Al³⁺ can serve as a charge compensator in the formation of space charge zones with electrons. These innovative findings provide unprecedented insight into the charge storage mechanism of AIBs. To complete the study, the researchers used 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .
