HPLC of Formula: 65039-09-0In 2022, Qu, Minghe;Li, Shenshen;Chen, Jian;Xiao, Yunqin;Xiao, Jijun published 《Ion transport in ionic liquid/poly(vinylidene fluoride) system under electric fields: A molecular dynamics simulation》. 《Colloids and Surfaces, A: Physicochemical and Engineering Aspects》published the findings. The article contains the following contents:

Mol. dynamics simulations were applied to explore the ion transport in five ionic liquid/poly(vinylidene fluoride) (IL/PVDF) systems under different elec. fields where the cation is 1-ethyl-3-methylimidazolium (EMI⁺) and the anions are Cl^–, Br^–, BF₄^–, PF₆^– and trifluoromethanesulfonate (TfO^–) sep., and each system contains about 40 wt% of IL. The structural properties were analyzed by the following calculations as elec. fields increase. The pair correlation function reveals that the local spatial structure of ion pairs can be split into two types, which tend to disorder; the dihedral angle and mean square radius of gyration show that PVDF chains tend to straighten. The ion transport properties were studied by the ion-pair intermittent time correlation function and continuous time correlation function, the diffusion coefficient and mobility of anions and cations as elec. fields increase. The simulation results illustrate that ion transport is intensified. In addition, the relationship between diffusion coefficient and the elec. fields can be fitted into an exponential function, and the fitting parameters are strongly related to the local structure of the ion pairs, and the relationship between ideal conductivity and the elec. fields has the same law. Specially, the anions mobility is determined by the anions volume under the stronger elec. fields, and the smaller the anion volume, the greater the mobility.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

The article was appeared in 《ChemSusChem》. They have made some progress in their research.Category: imidazoles-derivatives The article mentions the following:

Al-based batteries are promising next-generation rechargeable batteries owing to the abundance of raw materials and their high potential energy d. The Al-S system has attracted considerable attention because of its high energy d. and low cost. However, its low discharge voltage plateau (0.6-1.2 V) hampers its practical application. Herein, eight ionic liquids or deep eutectic solvents were studied as electrolyte candidates for an Al-S cell. This was the first study to demonstrate that an Al-S cell based on an AlCl₃/acetamide electrolyte (1.3 molar ratio) showed high discharge voltage plateaus (1.65-1.95 V) and a charging cut-off voltage of 2.5 V in Al-S cells. An Al-S cell of 0.33 mAh capacity with the AlCl₃/acetamide electrolyte successfully lit up a red LED (forward voltage 1.6-2.0 V) for around 2 h. This work may help in promoting the development of high-performance and low-cost Al-S cells. 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 chlorideIn 2022, Scovazzo, Paul;Sullivan-Gonzalez, Frances;Amos, Ryan published 《Hydrogen-bond acceptance’s role in designing room temperature ionic liquid (RTIL) membranes for gas separations, Part II, beta-parameter and relative humidity impacts on membrane stability》. 《Journal of Membrane Science》published the findings. The article contains the following contents:

RTIL H-bond acceptance ability and the porous support’s polymer are important factors for RTIL-membrane stability. Under dry conditions, the stability of RTILs supported in porous polyethersulfone decreased with increasing beta-parameters. Under humid conditions, the CH₄-permeance vs. rH relationship for 1-ethyl-3-methylimidazolium trifluoromethanesulfonate changed when the porous support’s polymer changed. With proper selection of the porous support’s chem., it is possible to create RTIL-membranes that are stable over a range of rHs for both low and high Beta-parameter RTILs. However, in some RTIL/polymer supported membranes, a reversible and repeatable dual mode CH₄-permeance behavior occurs with significantly lower CH₄-permeances at elevated rHs. This dual mode is the result of RTIL/polymer interaction and not the result of changes in RTIL/transporting gas phys. chem. RTIL capillary rise vs. rH measurements are consistent with, but insufficient to state that, the dual mode results from changes in the RTIL/polymer interfacial capillary forces. Increasing gas rH leads to increased gas permeability with greater permeability enhancement for CH₄ transport. This leads to decreased CO₂/CH₄ selectivity with increasing rH. Mixed-gas CO₂/CH₄ separation data for three benchmark RTIL-membranes, verified to be stable from 0%-rH to >90%-rH, confirmed this permeance increase and selectivity decrease statement. And 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) was used in the research process.

Tu, Jiguo;Chang, Cheng;Wang, Mingyong;Guan, Wei;Jiao, Shuqiang published 《Stable and low-voltage-hysteresis zinc negative electrode promoting aluminum dual-ion batteries》 in 2022. The article was appeared in 《Chemical Engineering Journal (Amsterdam, Netherlands)》. They have made some progress in their research.SDS of cas: 65039-09-0 The article mentions the following:

Compared with the widely developed pos. electrodes, the research on the high stability neg. electrodes is far from in-depth in nonaqueous Al batteries. In order to fundamentally solve these key problems, including Al dendrites, corrosion and pulverization, it is urgent to develop an alternative stable neg. electrode. Herein, the corrosion-resistant, low-voltage-hysteresis and stable Zn is demonstrated as a promising neg. electrode. Since the deposited Al particles on the Zn electrode are prior to Zn in the stripping reaction, Zn electrode can remain good structural integrality, thus presenting great cycling stability and corrosion resistance. Importantly, the results in Al-Zn sym. cells indicate that Zn possesses the ultra-low voltage hysteresis (∼17 mV at 0.5 mA cm^-2), superior cycling stability (800 cycles at 1.0 mA cm^-2) and Al plating/stripping reversibility characteristics. Addnl., the Zn-graphite full battery based on Zn as neg. electrode and flake graphite as pos. electrode delivers stable discharge capacity of 81.1 mAh g^-1 over 300 cycles. The results in this work open an effective approach for constructing corrosion-resistant, low-voltage-hysteresis and stable neg. electrode, further indicating that Zn is great promising as neg. electrode for Al dual-ion batteries. And 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) was used in the research process.

Synthetic Route of C6H11ClN2《Soluble Electrolyte-Coordinated Sulfide Species Revealed in Al-S Batteries by Nuclear Magnetic Resonance Spectroscopy》 was published in 2022. The authors were Jay, Rahul;Jadhav, Ankur L.;Gordon, Leo W.;Messinger, Robert J., and the article was included in《Chemistry of Materials》. The author mentioned the following in the article:

Rechargeable aluminum-sulfur (Al-S) batteries have recently garnered significant interest to the low cost, earth abundance, safety, and high theor. capacity of the electrode materials. However, Al-S batteries exhibit many challenges that plague other metal-sulfur battery systems, including significant capacity fade of the sulfur electrode due to the formation of electrolyte-soluble reaction intermediates. Here, Al-S cells using chloroaluminate-containing ionic liquid electrolytes were investigated up from the mol. level using multidimensional solid-state ²⁷Al MAS NMR spectroscopy, XPS, X-ray diffraction (XRD), and electrochem. measurements. Solid-state ²⁷Al single-pulse NMR measurements acquired on cycled sulfur electrodes containing electrolyte-soaked separator revealed multiple discharge products, which were distinguished into liquid- and solid-phase products based on ²⁷Al chem. exchange and nutation NMR experiments During discharge, electrolyte-soluble sulfide species form that coordinate with the AlCl₄^– chloroaluminate anions, resulting in (S_xAlCl₄)^y- electrolyte complexes. These electrolyte-coordinated sulfide species persist upon charge, resulting in the loss of active mass that explains the significant capacity fade observed upon galvanostatic cycling. XPS, XRD, and solid-state ²⁷Al NMR measurements reveal that solid amorphous Al₂S₃ forms reversibly upon discharge. The results highlight the technol. importance of understanding how electrolyte-soluble sulfide species coordinate with the complex electroactive species used in multivalent metal-sulfur batteries, which can affect their reversibility and electrochem. properties. To complete the study, the researchers used 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .

Recently, an important focus of material research has been aimed at more sustainable smart materials with biodegradable, biocompatible properties such as those based on cellulose (Cell), made stimuli-responsive with the addition of multiwall carbon nanotubes (CNT). Formulated as fibers, such materials have potential applications in smart clothing and wearable’s in actuation or sensing function. In order to ensure maximum performance, an optimal driving voltage and regime must be chosen. In addition to the quant. effects, the actuation response also qual. and mechanistically changes, depending on the voltage range. The linear actuation measurements combined with cyclic voltammetry and square wave potential steps were performed in aqueous lithium bis(trifluoromethane)sulfonimide solution The Cell-CNT fiber actuation response properties were investigated at different potential ranges: 0.8-0.0 V, 0.8 V to – 0.3 V, 0.8 V to – 0.55 V and 0.65 V to – 0.6 V, observing a change in actuation direction between the ranges. Not just the potential range but also the driving frequency had an impact on the response, therefore, the selection of driving parameters is shown to be critical for controllable performance.

COA of Formula: C6H11ClN2《Structural and functional properties of collagen from tilapia scales pretreated by heat-assisted ionic liquids》 was published in 2022. The authors were Huang, Liurong;Ding, Shuang;Chen, Tian;Wu, Ruike;Wang, Xinyu;Jia, Shifang, and the article was included in《Journal of Applied Polymer Science》. The author mentioned the following in the article:

This paper explores the structural and functional properties of collagen from tilapia scales pretreated by heat-assisted ionic liquids (ILs). Results show that the solubility of collagen was significantly influenced by the type and concentration of ILs. With the increase of IL concentration, a remarkable decrease in solubility of collagen was seen. Fluorescence spectra show that heat and IL pretreatments induced the exposure of chromophores. Changes in sodium dodecyl sulfate-polyacrylamide gel electrophoresis indicated that subunits of collagen regenerated from most of the IL solvent systems were not destroyed. The functional properties of regenerated collagen were evaluated by gel strength, viscosity, water-binding capacity, and emulsifying capacity. Results show that all heat-assisted ILs pretreatments improved the gel strength and viscosity, and the highest gel strength and viscosity were both obtained in the collagen pretreated by heat-assisted [EMIM]Cl. Heat-assisted [BMIM]BF₄ pretreatment exhibited the lowest water-binding capacity. Heat-assisted [BDMIM]Cl pretreatment indicated superior effect on improving emulsifying capacity than other pretreatments due to its ability to break most of the hydrogen bonds in collagen mols., resulting in the formation of new re-aggregates with higher solubility and more hydrophobic groups. And 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) was used in the research process.

Due to the advantages of high temperature stability, low corrosion, and good heat transfer performance, potassium nitrate aqueous solution holds application potential in absorption systems. In order to further improve its absorption ability, ionic liquids (ILS) such as [Emim]Cl, [Emim]Ac, and [Emim]Br were selected as additives. In this paper, vapor pressures of four {KNO₃ + ILS + H₂O} ternary systems were measured by a dynamic b.p. method, including {KNO₃ + [Emim]Cl + H₂O}, {KNO₃ + [Emim]Ac + H₂O}, {KNO₃ + [Emim]NO₃ + H₂O}, and {KNO₃ + [Emim]Br + H₂O}. Molar ratios between KNO₃ and ILs were 1:1 for these systems, and the total absorbent mass fractions were in the range of 0.20 to 0.70. Exptl. data were regressed by Antoine-type equations, and the average absolute relative deviations (AARD%) between the exptl. and calculated values were no more than 0.78%, which showed good consistency of these experiments Vapor-liquid equilibrium behavior of these different ionic liquid ternary systems were compared and [Emim]Ac showed best performance in reducing vapor pressure at relatively higher mass fractions.

Ren, Fei;Wang, Jinwei;Yu, Jinglin;Zhong, Cheng;Xie, Fengwei;Wang, Shujun published 《Green synthesis of acetylated maize starch in different imidazolium carboxylate and choline carboxylate ionic liquids》. The research results were published in《Carbohydrate Polymers》 in 2022.Recommanded Product: 65039-09-0 The article conveys some information:

This work demonstrates that acetylated maize starches (AMS) with varied degree of substitution (DS, 0.26-2.63) was synthesized in ionic liquids (ILs) (imidazolium chloride, imidazolium carboxylate and choline carboxylate) at 85°C without catalyst. The DS of AMS and reaction efficiency increased with decreasing alkyl chain length of cations or anions, while decreased as the choline cation replaced the imidazolium cation and the chloride anion replaced the acetate anion. The AMS synthesized in imidazolium-based ILs exhibited much higher hydrophobicity and thermal stability than the native starch. Rheol. properties of ILs and ATR-FTIR anal. of acetic anhydride/ILs mixtures indicated that a shorter alkyl side chain or the combination of an imidazolium cation and an acetate anion gave ILs lower viscosities and weaker interactions between acetic anhydride mols., which favored the acetylation of starch. These findings provide insights into the design of green processes to modify starch and the application of acetylated starch. The experimental procedure involved many compounds, such as 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .

The article was appeared in 《Journal of the Iranian Chemical Society》. They have made some progress in their research.Application In Synthesis of 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride The article mentions the following:

In this study, liquid-liquid equilibrium data of an aqueous two-phase system (ATPS) composed of alcs. (ethanol, 1-propanol, or 2-propanol) and small-mol. organic compound (sodium citrate, sodium tartrate, sucrose, maltose, and lactose) was extensively investigated at 298.1 K ± 0.1 K. The binodal curves were summarized through the empirical nonlinear equations with the lowest standard deviation. The contents of alcs. and organic salts in ATPS were accurately determined by gas chromatog. and UV spectrophotometer. The phase-forming abilities of alcs. were ranked in the following order, 1-propanol > 2-propanol > ethanol, resp. The ATPS composed of saccharides was difficult to form two phases due to the high viscosity. The salting-out abilities of sodium citrate (C₆H₅Na₃O₇) were better than sodium tartrate. 1-propanol/ C₆H₅Na₃O₇ATPS had larger biphase areas, it was further applied to concentrate various ionic liquids including [C₂mim]BF₄, [C₄mim]BF₄, [C₄mim]Cl and [C₈mim]Cl. The results showed that alc./organic salt ATPS had a better extraction rate to imidazole-type ionic liquids Ionic liquids were mainly distributed in the top phase (alc.-rich phase). And 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) was used in the research process.
