The article was appeared in 《Advanced Energy Materials》. They have made some progress in their research.Computed Properties of C6H11ClN2 The article mentions the following:

Rechargeable aluminum ion batteries (AIBs) are one of the most promising battery technologies for future large-scale energy storage due to their high theor. volumetric capacity, low-cost, and high safety. However, the low capacity of the intercalation-type cathode materials reduces the competitiveness of AIBs in practical applications. Herein, a conversion-type FeF₃-expanded graphite (EG) composite is synthesized as a novel cathode material for AIBs with good conductivity and cycle stability. Combined with the introduction of a single-wall carbon nanotube modified separator, the shuttle effect of the intermediate product, FeCl₂, is significantly restrained. Moreover, enhanced coulombic efficiency and reversible capacity are achieved. The AIB exhibits a satisfying reversible specific capacity of 266 mAh g^-1 at 60 mA g^-1 after 200 cycles, and good Coulombic efficiency of nearly 100% after 400 cycles at a c.d. of 100 mA g^-1. Ex situ X-ray diffraction and XPS are applied to explore the energy storage mechanism of FeF₃ in AIBs. The results reveal that the intercalation of Al³⁺ species and the reduction of Fe³⁺ species occurrs in the discharge process. These findings are meaningful for the fundamental understanding of the FeF₃ cathode for AIBs and provide unprecedented insight into novel conversion type cathode materials for AIBs.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

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) .

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.

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.

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.

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 starting material for the preparation of 1-ethyl-3-methylimidazolium chloride/tetrafluoroborate (EMI.Cl.BF4) molten salt for electrochemical studies; a solvent as well as catalyst for the depolymerization of oak wood lignin.HPLC of Formula: 65039-09-0

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 research results were published in《Bioresource Technology》 in 2022.Safety of 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride The article conveys some information:

There is an increasing interest in deep eutectic solvent (DES) and ionic liquid (IL) for lignin and 5-hydroxymethylfurfural (HMF) production from lignocellulosic biomass, but their economic costs raise great concerns. In this study, the effects of DES (ZnCl₂-lactic acid)/IL([EMIM]Cl)/metal catalysts (CuCl₂-CrCl₂) recycling time, acetone/water washing volume, HMF yield, and production capacity on total capital investment, annual operating cost, and net present value (NPV) of the refinery were elucidated. Results showed that annual operating cost was highly associated with DES/IL/metal catalysts recycling time as it determined raw materials cost. The HMF MSP of $16453/MT for the base case (ZnCl₂/lactic acid recycling 5 times, acetone/water washing 5 volumes, CuCl₂-CrCl₂-[EMIM]Cl recycling 10 times, HMF yield of 55%, and production capacity of 100 MT/h) was achieved with an IRR of 10%. Sensitivity anal. identified the unit costs of lactic acid and [EMIM]Cl as the dominant contributors to the HMF MSP. And 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) was used in the research process.

Today I want to share an article with you. The article is 《Solution-Spinning of a Collection of Micro- and Nanocarrier-Functionalized Polysaccharide Fibers》,you can find this article in 《Macromolecular Materials and Engineering》. The following contents are mentioned:

Continuous polysaccharide fibers and nonwovens-based on cellulose, hydroxypropyl cellulose, chitosan, or alginate-containing biopolymeric microcapsules (MC) or mesoporous silica nanoparticles (MSN) are prepared using a wet-spinning or solution blowing technique. The MCs are homogeneously distributed in the fiber matrixes whereas the MSNs form discrete micron-sized aggregates as demonstrated using scanning electron-, fluorescence-, and confocal microscopy. By encapsulating the model compound pyrene, it is shown that 95% of the substance remains in the fiber during the formation process as compared to only 7% for the nonencapsulated substance. The material comprising the MC has a strong impact on the release behavior of the encapsulated pyrene as investigated using methanol extraction MCs based on poly(L-lactic acid) prove to be practically impermeable with no pyrene released in contrast to MCs based on poly(lactic-co-glycolic acid) which allow for diffusion of pyrene through the MC and fiber as visualized using fluorescence microscopy.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

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

Rechargeable aluminum-ion batteries, RAIBs, as a prime candidate for next-generation batteries, have attracted much attention due to their extremely high anode capacity and good safety. However, the lack of matching high-capacity cathode materials and reasonable design limit their practical development. Herein, core-shelled Sb@C nanorods are prepared by polymer coating and thermal reduction as a metal-based cathode for RAIBs. The carbon shell and graphene aerogel interlayer effectively block the diffusion and shuttling of charging products, thus exhibiting excellent electrochem. performance. This Al-Sb battery delivers an initial discharge capacity of 656 mA h g-¹ at 100 mA g^-1, a stable discharge voltage of 0.9 V, and excellent cycling stability maintained at 306 mA h g^-1 after 500 cycles at 1 A g^-1. Serial characterizations are used to monitor the structural changes of Sb in reversible reactions and to determine the configuration of the charged products, showing that the product exists in the form of [SbCl₄]⁺ cations, i.e., a five-electron transfer reaction occurs with a very high theor. capacity (1100 mA h g^-1). This study sheds light on the energy storage mechanism of a metallic Sb cathode in RAIBs, and provides new insights into the study of high-capacity cathodes and the rational design of battery structures. The experimental procedure involved many compounds, such as 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .

Quality Control of 1-Ethyl-3-methyl-1H-imidazol-3-ium chlorideIn 2022, Wang, Liling;Wang, Yanbin;Qin, Yuchuan;Liu, Bentong;Zhou, Yifeng published 《Extraction and Determination of Protein from Edible Oil Using Aqueous Biphasic Systems of Ionic Liquids and Salts》. 《Food and Bioprocess Technology》published the findings. The article contains the following contents:

This study aimed to develop the extraction method of protein from edible oil for rapid detection. Firstly, aqueous biphasic systems (ABS) based on six hydrophilic ionic liquids (ILs) and three salts were developed and the phase diagram was drawn by turbidimetric point method. The binodal curves were fitted to the Merchuk equation. On this basis, the ABS composed of IL and salt were applied to extract protein from edible oil. The type of IL or salt, IL concentration, salt concentration, oil mass, extraction pH, and temperature on the extraction efficiency of protein from oil were investigated. The results showed that the optimum conditions for the extraction of protein from edible oil with ABS were as follows: 50% (w/v) K3PO4, 20% (w/v) [Bmim]Cl at 35°C, and pH 9.0. Under the optimal conditions, the protein extraction efficiency was almost 100%. Also, the extraction mechanism was studied and the main driving factors of protein extraction may be the hydrophobicity, electrostatic interaction, and salting-out between mols. Finally, the method was used to detect the com. edible oils from different sources. The results showed that the ABS could also be used to extract protein from other edible oils. In conclusion, the IL-based ABS method is simple and rapid for protein extraction from edible oil, and will highlight novel possibilities in the large-scale separation and purification of protein from oily solution And 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) was used in the research process.
