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. And 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) was used in the research process.

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) .

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) .

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 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.

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) .

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:

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.
