Category: imidazoles-derivativesIn 2022, Yahya, M. S.;Lau, E. V. published 《Dominance of hydrophobic attraction in attachment of microbubbles and Graphene oxide (GO)》. 《Chemical Engineering Science》published the findings. The article contains the following contents:

This paper presents the synthesis of GO-coated microbubbles which would be useful for environmental remediation and enhanced heat transfer applications. The mechanism of microbubble-GO attachment including electrostatic interactions, hydrophobic attraction, contact angle and Gibb’s free energy were determined Preliminary experiments indicated that water alone is not favorable, which thus necessitated the use of a bridging surfactant. The optimum attachment between microbubbles and GO occurred at the GO’s isoelec. point (IEP) in the ionic liquid as surfactant (IL), in which the IL concentration allowed GO to achieve maximum hydrophobicity. Therefore, it is inferred that hydrophobic attraction is the dominant force for microbubble-GO attachment with minor contributions from electrostatic interactions. Further studies showed that the longest carbon chain length IL, i.e. 1-Dodecyl-3-methylimidazolium chloride ([C₁₂mim]Cl) produced the most conducive environment for microbubble-GO attachment at its IEP concentration of 350 ppm.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

Electric Literature of C6H11ClN2《Synthesis of novel ionic liquid modified AC-Fe3O4 magnetic nanocomposite for the adsorption of heavy metals in wastewater》 was published in 2022. The authors were Taziwa, R. T.;Mungondori, H.;Zarima, Takunda, and the article was included in《Asian Journal of Chemistry》. The author mentioned the following in the article:

This study reports a novel magnetic nanoadsorbent prepared from magnetite (Fe₃O₄) as the magnetic core, activated carbon from coal fly ash and an ionic liquid (1-methyl-3-ethylimidazolium chloride). The magnetic nanoadsorbent was synthesized via co-precipitation and characterized by FTIR, XRD, TEM, EDS and BET surface area anal. Batch adsorption studies on cadmium (Cd²⁺) and lead (Pb²⁺) solutions such as effect of pH, contact time and adsorbent dosage were carried out. The data was analyzed using the Langmuir and Freundlich models. The results revealed that the optimal adsorption conditions for both metal ions on synthesized nanoadsorbent were pH 6, 200 min, adsorbent dosage of 1.5 g/L, initial ion concentration of 10 ppm and a temperature of 25°C. The data obtained in the adsorption of Cd²⁺ and Pb²⁺ best fitted the Freundlich isotherm, with R2 values of 0.998 and 0.995, resp. Thermodn. and kinetic studies suggested that adsorption of both metal ions on the IL-AC-Fe₃O₄ nanocomposite followed the pseudo first order model. The synthesized nanoadsorbent (IL-AC-Fe₃O₄) exhibits good adsorption properties and has great potential in a water treatment technol.

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.

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) .

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.

Zhao, Jikai;Lee, Juhee;Wang, Donghai published 《An integrated deep eutectic solvent-ionic liquid-metal catalyst system for lignin and 5-hydroxymethylfurfural production from lignocellulosic biomass: Technoeconomic analysis》. 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.

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.
