The research results were published in《Composites, Part A: Applied Science and Manufacturing》 in 2022.Computed Properties of C6H11ClN2 The article conveys some information:

Ionic liquid 1-Ethyl-3-methylimidazolium chloride was employed to promote the exfoliation of hexagonal boron nitride (BN) to fabricate the boron nitride nanosheets (BNNSs). The BNNSs were then surface activated by covalently attaching mercapto groups on their surfaces. The surface-activated BNNS nanoparticles (S@BNNSs) were incorporated in a carboxylated styrene-butadiene rubber matrix for preparing thermal management materials. The developed material was provided with superior mech. properties, satisfied thermal conductivity and strong storage modulus attributing to the two-dimensional structure of the filler and the enhanced interfacial interaction between the filler and matrix. The filler-filler and filler-matrix networks in the composite system were comprehensively analyzed. The thermal management applications were also demonstrated using an IR camera and a com. thermoelec. generator. All the performances demonstrated their potential use as thermal management materials in electronic devices.

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 solvent as well as catalyst for the depolymerization of oak wood lignin; a solvent in the hydrolysis of hemicellulose (xylan) to xylose using Brønsted acid catalysts.Name: 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride

Name: 1-Ethyl-3-methyl-1H-imidazol-3-ium chlorideIn 2022, Hou, Qidong;Bai, Chuanyunlong;Bai, Xinyu;Qian, Hengli;Nie, Yifan;Xia, Tianliang;Lai, Ruite;Yu, Guanjie;Rehman, Mian Laiq Ur;Ju, Meiting published 《Roles of Ball Milling Pretreatment and Titanyl Sulfate in the Synthesis of 5-Hydroxymethylfurfural from Cellulose》. 《ACS Sustainable Chemistry & Engineering》published the findings. The article contains the following contents:

Production of 5-hydroxymethylfurfural (HMF) from cellulose has been expected for a long time, but most catalytic systems generally give low yield and selectivity due to the difficulty of balancing cellulose deconstruction with the uncontrollable degradation of the target product under harsh conditions. Here we show that the ball milling pretreatment could markedly facilitate the conversion of microcrystalline cellulose to HMF by titanyl sulfate (TiOSO₄). The ball milling pretreatment remarkably decreases the degree of crystallinity of microcrystalline cellulose with a reduction of mol. weight via disrupting the hydrogen bond and partially breaking the β-1,4-glycosidic bond. TiOSO₄ functions as both Lewis and Bronsted acid to catalyze the efficient conversion of cellulose with high HMF yield (45.4%), far exceeding that (14.1%) from untreated cellulose. The reaction pathway was revealed by liquid chromatograph-mass spectra anal. In addition, phosphorylated titanium dioxide also afforded a notable HMF yield (21.8%), showcasing the great potential of Ti-based heterogeneous catalyst.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

The article was appeared in 《Solid State Ionics》. They have made some progress in their research.Electric Literature of C6H11ClN2 The article mentions the following:

Mol. dynamics (MD) simulations were applied to explore the ion transport in six ionic liquid/poly(vinylidene fluoride) (IL/PVDF) systems where the cation is 1-ethyl-3-methylimidazolium ([EMIM]) and the anions are [Cl], [Br] [BF₄], [PF₆], trifluoromethanesulfonate ([TfO]) and bis(trifluoromethanesulfonyl)imide ([NTf₂]) sep., and each system contains about 40 wt% IL. The glass transition temperature (T_g = 204 K) of [EMIM][NTf₂]/PVDF system is good agreement with the exptl. value (200 K). Transference number of ions, ideal conductivity and viscosity can be calculated based on diffusion coefficient The power law shows mobilities of anions and cations are seen to exhibit a “superionic” behavior when considering all the anions (cations) together. Overall, for the same IL/PVDF system, with the increase of temperature, both the ion-pair relaxation times and lifetimes decrease, while diffusion coefficients of ions increase, so ion motion is intensified. The transference numbers of anions and cations show upward and downward trends resp., indicating that the diffusion coefficients of cations decrease faster than that of the anions. The conductivity gradually increases, and the viscosity gradually decreases. For different IL/PVDF systems, the chem. properties of ion pairs are the main factors affecting ion-pair relaxation times and lifetimes, diffusion coefficients, the conductivity and viscosity at lower temperatures However, the influence gradually weakens as the temperature increases, and the IL/PVDF systems with a large Tg will have smaller the diffusion coefficients, conductivity, as well as higher viscosity at higher temperatures1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

Zhang, Juyan;Zhang, Lan;Zhao, Yunlong;Meng, Jiashen;Wen, Bohua;Muttaqi, Kashem M.;Islam, Rabiul Md.;Cai, Qiong;Zhang, Suojiang published 《High-Performance Rechargeable Aluminum-Ion Batteries Enabled by Composite FeF₃ @ Expanded Graphite Cathode and Carbon Nanotube-Modified Separator》 in . 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.

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.

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.

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.
