Although ionic thermoelec. (iTE) materials can have very high thermopower, it is of great significance to develop novel methods to further improve the ionic thermopower and figure of merit (ZTi). Here, significant improvement in the thermopower and thus the ZTi value of an ionogel by cationic doping, is reported. Doping sodium dicyanamide (Na:DCA) into the ionogels of poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) and 1-ethyl-3-methylimidazolium dicyanamide (EMIM:DCA) that is an ionic liquid can greatly enhance the thermopower. This is attributed to the interactions between the doped Na+ cations and DCA- anions, thereby increasing the difference in the mobilities of EMIM+ cations and DCA- anions. Moreover, through the combination with the solid networks engineering by an anti-solvent to PVDF-HFP, the PVDF-HFP/EMIM:DCA ionogel doped with 0.5 mol% Na+ with respect to EMIM+ exhibits an ionic thermopower of 43.8 ± 1.0 mV K-1, ionic conductivity of 19.4 ± 0.3 mS cm^-1 and thermal conductivity of 0.183 W m-1 K-1 at the relative humidity of 85% and room temperature The corresponding ZTi value thus reaches 6.1 ± 0.4, much higher than the previous ZTi records of iTE materials. These ionogels can be used in the iTE capacitors for the thermoelec. conversion.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

Application of cas: 65039-09-0 | Meng, Pengyu et al. published an article in 2022

Meng, Pengyu;Huang, Jian;Yang, Zhaohui;Wang, Fei;Lv, Teng;Zhang, Jiao;Fu, Chaopeng;Xiao, Wei published 《A Low-Cost and Air-Stable Rechargeable Aluminum-Ion Battery》 in 2022. The article was appeared in 《Advanced Materials (Weinheim, Germany)》. They have made some progress in their research.Product Details of 65039-09-0 The article mentions the following:

Rechargeable aluminum-ion batteries (AIBs) are promising for large-scale energy storage due to the abundant reserves, low cost, and high capacity of the Al anode. However, the development of AIBs is currently hindered by the usage of AlCl₃/1-ethyl-3-methylimidazolium chloride electrolyte, which is expensive, highly corrosive, and extremely air-sensitive. Herein, a new hydrated eutectic electrolyte (HEE) composed of hydrated aluminum perchlorate and succinonitrile for low-cost, noncorrosive, and air-stable AIBs is reported. Crystal water in the hydrated aluminum perchlorate plays a vital role in forming the HEE, in which one H₂O and five succinonitrile mols. coordinate with one Al³⁺ ion. The optimized ratio of Al(ClO₄)₃·₉H₂O to succinonitrile is 1:12. When combining with the self-doped polyaniline cathode, the associated AIB delivers a high discharge capacity of 185 mAh g^-1 over 300 cycles; and the charge/discharge mechanism in the HEE is studied exptl. and theor. The HEE is nonflammable, air-stable, and noncorrosive, thus enabling good air tolerance and facile fabrication of AIBs. To complete the study, the researchers used 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .

Category: imidazoles-derivatives《A porous thienyl cyclodextrin polymer synthesized in a homogeneous ionic liquid catalytic system for the rapid removal of pharmaceuticals and personal care products (PPCPs)》 was published in 2022. The authors were Tu, Yizhou;Wang, Huimin;Yang, Pingping;Xu, Guizhou;Hu, Xuejiao;Li, Aimin;Xie, Xianchuan, and the article was included in《Green Chemistry》. The author mentioned the following in the article:

Pharmaceuticals and personal care products (PPCPs) are widely distributed in aquatic environments due to their large consumption and low biodegradability, causing ecol. risks. In this study, a porous thienyl cyclodextrin polymer (Th-CDP) with a sp. surface area of 730 m² g^-1 was synthesized in an ionic liquid system for the first time to remove PPCPs. The green and recyclable 1-ethyl-3-methylimidazolium chloride/ferric chloride ([EMIm]Cl/FeCl₃) ionic liquid was synthesized as a solvent and catalyst, superior to traditional toxic organic solvents and heterogeneous catalysts. In Th-CDP synthesis, thienyl cyclodextrin (ThCD) was synthesized, followed by polymerization with the three-dimensional crosslinking agent tri-Me orthoformate (Tmof) in [EMIm]Cl/FeCl₃ via the Friedel-Crafts alkylation reaction. Th-CDP shows excellent adsorption towards the studied PPCPs (diclofenac, ibuprofen, carbamazepine, and sulfamethoxazole) due to the rich pore structure. In particular, Th-CDP achieved 90% removal of hydrophobic diclofenac and ibuprofen in 5 min, and the rate constants were 16.7 and 10.5 times higher than those of activated carbon, resp. The adsorption capacity of Th-CDP is related to the mol. weight and pKa of the compound, and is about twice that of activated carbon. Th-CDP has more pronounced adsorption advantages over activated carbon for acidic compounds due to its pos. charge under neutral conditions. In addition, multiple mechanisms, including hydrophobic interaction caused by thiophene and cyclodextrin, electrostatic interaction, and heteroatom interaction (24.8% S content), enable Th-CDP to efficiently remove PPCPs. Moreover, Th-CDP has great application potential due to its excellent regenerability, anti-interference ability, and green synthesis process. 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 Physical Chemistry C》. They have made some progress in their research.Safety of 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride The article mentions the following:

X-ray Raman spectroscopy (XRS) is an emerging spectroscopic technique that utilizes inelastic scattering of hard X-rays to study X-ray absorption edges of low Z elements in bulk material. It was used to identify and quantify the amount of carbonyl bonds in a cathode sample, in order to track the redox reaction inside metal-organic batteries during the charge/discharge cycle. XRS was used to record the oxygen K-edge absorption spectra of organic polymer cathodes from different multivalent metal-organic batteries. The amount of carbonyl bond in each sample was determined by modeling the oxygen K-edge XRS spectra with the linear combination of two reference compounds that mimicked the fully charged and the fully discharged phases of the battery. To interpret exptl. XRS spectra, theor. calculations of oxygen K-edge absorption spectra based on d. functional theory were performed. Overall, a good agreement between the amount of carbonyl bond present during different stages of battery cycle, calculated from linear combination of standards, and the amount obtained from electrochem. characterization based on measured capacity was achieved. The electrochem. mechanism in all studied batteries was confirmed to be a reduction of double carbonyl bond and the intermediate anion was identified with the help of theor. calculations X-ray Raman spectroscopy of the oxygen K-edge was shown to be a viable characterization technique for accurate tracking of the redox reaction inside metal-organic batteries. And 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) was used in the research process.

In this study, waste peanut shells were sulfur-impregnated and used as acid catalysts in the presence of an ionic liquid for the conversion of fructose, glucose, and cellulose into 5-hydroxymethylfurfural, a useful chem. intermediate for biofuel production Effects of sulfur-doping duration (1 h and 5 h), solvent type and proportion, reaction temperature (130°C, 140°C, and 150°C), time (30-240 min), catalyst-to-substrate ratio (1-2.5 m/m), and agricultural residue (peanut shell, Canada wheat straw, water hyacinth, stalk, and reed) on HMF yields were investigated. Monophasic and biphasic ionic liquids such as [amim]Cl, [bmim]HSO₄, and [emim]Cl were employed in combination with choline chloride and DMSO to improve HMF yields. Results show that peanut shells subjected to prolonged sulfur impregnation produced higher HMF yields. At 130°C and 2 h, HMF yields from fructose and glucose reached 94.6% and 55.1%, resp. Higher reaction temperatures improved HMF yields and accelerated conversion rates for the sugar substrates. Moreover, HMF production from waste biomass namely, peanut shells, peanut stalk, Canadian wheat straw, reed, and water hyacinth were examined in sep. one-pot catalytic reactions. Overall, the study showed the effectiveness of sulfur-doped peanut shells as solid acid catalysts for the synthesis of HMF from various sources and the results may be used in designing large-scale production of furanic biofuel precursors from agricultural wastes.

Soheilmoghaddam, Farhad;Sharifzadeh, Ghorbanali;Adelnia, Hossein;Wahit, Mat Uzir published 《Development of Regenerated Cellulose/Citric Acid Films with Ionic Liquids》 in 2022. The article was appeared in 《Journal of Polymers and the Environment》. They have made some progress in their research.Category: imidazoles-derivatives The article mentions the following:

Nowadays, the importance of green and biodegradable plastics as viable substitutes for non-degradable petroleum-based materials is felt more than ever. Regenerated cellulose (RC) as a potential candidate suffers from poor processability and inferior properties, limiting its wide applications. In this study, it is demonstrated that citric acid (CA) enhances phys., mech., and thermal properties of RC films, due to RC-citric acid compatibility. 1-Ethyl-3-methylimidazolium chloride (EMIMCl) as a green ionic liquid was employed for the processing of RC. The optimum properties in terms of thermal stability, mech. strength, contact angle, water uptake, and oxygen permeability were achieved at 10 wt% of CA. However, further incorporation of CA adversely affected the film properties. This behavior was explained by the crosslinking and plasticizing effects of CA. Furthermore, in vitro cytotoxicity test demonstrated that RC/CA films are cytocompatible, suggesting the potential advantage of using these biopolymeric films for biomaterial and biol. applications.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

The article contains the following contents:

Since the energy storage mechanism of metal oxides, sulfides and selenides as cathode materials for aluminum ion batteries (AIBs) is still unclear, we successfully prepared multi-type cubic Co_mX_n (X = O, S, Se) by ZIF induction to study and analyze the energy storage mechanism. Through ex-situ XRD and XPS characterization, it is found that Co₃O₄ and Co₃S₄ only cause the valence change of Co element for energy storage due to the insertion and extraction of Al³⁺, while in CoSe₂, not only Co but also Se element is involved in the redox reaction. Besides, CoSe₂ exhibits higher operating voltage and excellent discharge capacity compared to Co₃O₄ and Co₃S₄. At 100 mA g^-1, CoSe₂ exhibits two operating voltages at 0.8 V and 1.8 V, and its first discharge capacity is 785.6 mAh g^-1, while the discharge voltage of Co₃O₄ and Co₃S₄ is only about 0.6 V, and the discharge capacities are 388.3 mAh g^-1 and 579.7 mAh g^-1, resp. After 500 cycles, the discharge capacities of CoSe₂ are maintained at 148.9 mAh g-1 at 500 mA g^-1. In addition, DFT proves that, compared with Co₃O₄ and Co₃S₄, CoSe₂ is more conducive to the surface adsorption and diffusion of AlCl-4, which lays a key foundation for the research on the cathode materials of aluminum batteries. To complete the study, the researchers used 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .

The article was appeared in 《Advanced Materials (Weinheim, Germany)》. They have made some progress in their research.HPLC of Formula: 65039-09-0 The article mentions the following:

Nonaqueous rechargeable aluminum batteries (RABs) of low cost and high safety are promising for next-generation energy storage. With the presence of ionic liquid (IL) electrolytes, their high moisture sensitivity and poor stability would lead to critical issues in liquid RABs, including undesirable gas production, irreversible activity loss, and an unstable electrode interface, undermining the operation stability. To address such issues, herein, a stable quasi-solid-state electrolyte is developed via encapsulating a small amount of an IL into a metal-organic framework, which not only protects the IL from moisture, but creates sufficient ionic transport network between the active materials and the electrolyte. Owing to the generated stable states at both pos.-electrode-electrolyte and neg.-electrode-electrolyte interfaces, the as-assembled quasi-solid-state Al-graphite batteries deliver specific capacity of ≈75 mA h g^-1 (with pos. electrode material loading ≈9 mg cm^-2, much higher than that in the conventional liquid systems). The batteries present a long-term cycling stability beyond 2000 cycles, with great stability even upon exposure to air within 2 h and under flame combustion tests. Such technol. opens a new platform of designing highly safe rechargeable Al batteries for stable energy storage.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.
