In 2019,Polymers (Basel, Switzerland) included an article by Kujawa, Joanna; Rynkowska, Edyta; Fatyeyeva, Kateryna; Knozowska, Katarzyna; Wolan, Andrzej; Dzieszkowski, Krzysztof; Li, Guoqiang; Kujawski, Wojciech. Reference of 1-Methyl-1H-imidazole. The article was titled 《Preparation and characterization of cellulose acetate propionate films functionalized with reactive ionic liquids》. The information in the text is summarized as follows:

The 1-(1,3-diethoxy-1,3-dioxopropan-2-ylo)-3-methylimidazolium bromide (RIL1_Br), 1-(2-etoxy-2 -oxoethyl)-3-methylimidazolium bromide (RIL2_Br), 1-(2-etoxy-2-oxoethyl)-3 -methylimidazolium tetrafluoroborate (RIL3_BF4) ionic liquids were synthesized. Subsequently, the dense cellulose acetate propionate (CAP)-based materials containing from 9 to 28.6 weight% of these reactive ionic liquids were elaborated. Reactive ionic liquids (RILs) were immobilized in CAP as a result of the transesterification reaction. The yield of this reaction was over 90% with respect to the used RIL. The physicochem. properties of resultant films were studied using NMR (NMR), SEM, energy dispersive X-ray (EDX), at. force microscopy (AFM), and thermogravimetric anal. (TGA). The RIL incorporation influenced the morphol. of films by increasing their surface roughness with the rise of RIL content. The thermal stability of CAP-based membranes was dependent on the nature of the ionic liquid Nevertheless, it was proven that CAP films containing RILs were stable up to 120-150°C. Transport properties were characterized by water permeation tests. It was found that the type and the amount of the ionic liquid in the CAP matrix substantially influenced the transport properties of the prepared hybrid materials. In the experiment, the researchers used 1-Methyl-1H-imidazole(cas: 616-47-7Reference of 1-Methyl-1H-imidazole)

In 2018,Organic & Biomolecular Chemistry included an article by Wang, Jing; Hu, Xuefeng; Wang, Dongli; Xie, Cao; Lu, Weiyue; Song, Jie; Wang, Ruifeng; Gao, Chunli; Liu, Min. Synthetic Route of C3H5N3. The article was titled 《2-Aminoimidazole facilitates efficient gene delivery in a low molecular weight poly(amidoamine) dendrimer》. The information in the text is summarized as follows:

Functional groups have shown great potential in gene delivery. However, a number of the reported functional groups can only overcome one certain physiol. barrier, resulting in limited transfection efficiencies. Based on the structure-activity relationships of both imidazolyl and guanidyl, we designed a novel multifunctional group, 2-aminoimidazole (AM), for gene delivery. On modifying with the AM group, the transfection efficiency of low mol. weight poly(amidoamine) (G2) was 200 times greater than the parent dendrimer in vitro. In contrast, the transfection efficiency of G2 showed a decreasing trend when it was grafted with imidazole. Assays revealed that the AM group played multiple roles in gene delivery, including condensing DNA into monodisperse nanoparticles of 80-90 nm in diameter, achieving nearly ten times higher cellular-uptake efficacy, and enhancing the abilities of endosome/lysosome escape and nuclear localization. What’s more, AM showed low toxicity. These results demonstrate that the AM group could be a promising tool in non-viral gene delivery.

Hennemann, Bruno L.; Moleta, Guilherme S.; Fuchs, Ana L.; Villetti, Marcos A.; Kuhn, Bruna L.; Rampelotto, Camila R.; Paz, Alisson V.; de Bona da Silva, Cristiane; Frizzo, Clarissa P. published an article in 2021. The article was titled 《Synergic effects of ultrasound and ionic liquids on fluconazole emulsion》, and you may find the article in Ultrasonics Sonochemistry.Reference of 1-Methyl-1H-imidazole The information in the text is summarized as follows:

The aim of this work was to evaluate the influence of US on the properties of the fluconazole emulsions prepared using imidazolium-based ILs ([Cn C1i.m.]Br). The effects of the preparation method (mech. stirring or US), US amplitude, alkyl chain length (of [C12C1i.m.]Br or [C16C1i.m.]Br), and IL concentration on the physicochem. properties were evaluated. Properties such as droplet size, span index, morphol., viscosity encapsulation efficiency, and drug release profile were determined The results showed that US-prepared emulsions had a smaller droplet size and smaller polydispersity (Span) than those prepared by mech. stirring. Addnl., the results showed that emulsions prepared with [C16C1i.m.]Br and US had spherical shapes and increased stability compared to emulsions prepared by MS, and also depended on the IL concentration The emulsion prepared by US at 40% amplitude had increased encapsulation efficiency. US provided a decrease in the viscosity of emulsions containing [C12C1i.m.]Br; however, in general, all emulsions had viscosity close to that of water. Emulsions containing [C16C1i.m.]Br had the lowest viscosities of all the emulsions. The emulsions containing the IL [C16C1i.m.]Br had more controlled release and a lower cumulative percentage of drug release. The IL concentration required to prepare these emulsions was lower than the amount of conventional surfactant required, which highlights the potential synergic effects of ILs and US in preparing emulsions of hydrophobic drugs.

Yue, Liang; Amirkhosravi, Mehrad; Ke, Kai; Gray, Thomas G.; Manas-Zloczower, Ica published their research in ACS Applied Materials & Interfaces in 2021. The article was titled 《Cellulose Nanocrystals: Accelerator and Reinforcing Filler for Epoxy Vitrimerization》.Name: 1-Methyl-1H-imidazole The article contains the following contents:

The novel vitrimerization concept of converting permanently crosslinked networks of thermoset polymers into dynamic exchangeable networks often relies on transesterification reactions. Transesterification exchange reactions, for example, in epoxy vitrimers, are usually contingent on equivalent ratios of hydroxyl to ester groups and large amounts of catalysts to achieve proper dynamic exchange capability. In general, postconsumer epoxy cured with anhydrides contains very few hydroxyl groups in the network, and it is challenging to convert it into efficient dynamic networks by vitrimerization. Here, we demonstrate that introducing cellulose nanocrystals as feedstock of external hydroxyl groups in the mechanochem. vitrimerization process could improve the exchange reaction rate as well as the thermomech. properties of the vitrimerized epoxy. This work offers an effective way to recycle and reprocess postconsumer epoxy/anhydride waste with inherent low ratios of hydroxyl to ester groups into higher value-added vitrimer nanocomposites.1-Methyl-1H-imidazole(cas: 616-47-7Name: 1-Methyl-1H-imidazole) was used in this study.

In 2018,Minrovic, Bradley M.; Jung, David; Melander, Roberta J.; Melander, Christian published 《New Class of Adjuvants Enables Lower Dosing of Colistin Against Acinetobacter baumannii》.ACS Infectious Diseases published the findings.Application In Synthesis of 1H-Imidazol-2-amine The information in the text is summarized as follows:

Antibiotic resistance has become increasingly prevalent over the past few decades, and this combined with a dearth in the development of new classes of antibiotics to treat multidrug resistant Gram-neg. infections has led to a significant global health problem and the increased usage of colistin as the last resort antibiotic. Colistin, however, presents dose dependent toxicity in the clinic. One potential approach to combating this problem is the use of an antibiotic adjuvant, a compound that is nontoxic to the bacteria that enhances the potency of colistin and ultimately allows for reducing dosing. Herein, we present a new urea-containing class of 2-aminoimidazole-based adjuvants that potentiates colistin activity against colistin-sensitive Acinetobacter baumannii. Lead compounds enabled 1000-fold reduction in the min. inhibitory concentration of colistin in vitro and showed efficacy in a Galleria mellonella infection model, representing the first step toward validating the potential of employing these adjuvants to lower colistin dosage.

《Ru-Pd Thermoresponsive Nanocatalyst Based on a Poly(ionic liquid) for Highly Efficient and Selectively Catalyzed Suzuki Coupling and Asymmetric Transfer Hydrogenation in the Aqueous Phase》 was written by Li, Xinjuan; Sun, Yanping; Wang, Shangyue; Jia, Xianbin. Computed Properties of C4H6N2 And the article was included in ACS Applied Materials & Interfaces in 2020. The article conveys some information:

The development of intelligent polymeric materials to precisely control the catalytic sites of heterogeneous catalysts and enable highly efficient catalysis of a cascade reaction is of great significance. The use of a polymer ionic liquid (PIL) containing 2 different anions facilitates the preparation of Ru-Pd catalysts with controllable phase transition temperatures and hydrophilic and hydrophobic surfaces. The combined multifunctionality, synergistic effects, micellar effects, aggregation effects, and temperature responsiveness of the nanocatalyst render it suitable for promoting selectively catalyzed Suzuki coupling and asym. transfer hydrogenation in H2O. Above the lower critical solution temperature (LCST) of the catalyst, it catalyzes only the coupling reaction with a high turnover number (TON) of ≤999.0. Below the LCST, the catalyst catalyzes only the asym. transfer hydrogenation with good catalytic activity and enantioselectivity. It is important that the catalyst can be simply and effectively recovered and recycled ≥10 times without significant loss of catalytic activity and enantioselectivity. This study also highlights the superiority of multifunctional heterogeneous catalysts based on PILs, which not only overcome limitations associated with low activity of heterogeneous catalysts but also realize selective reactions according to a temperature change, thereby improving the reactivity and enantioselectivity in multiple organic transformations. In the experiment, the researchers used many compounds, for example, 1-Methyl-1H-imidazole(cas: 616-47-7Computed Properties of C4H6N2)

The author of 《Imidazole and 1-Methylimidazole Hydrogen Bonding and Nonhydrogen Bonding Liquid Dynamics: Ultrafast IR Experiments》 were Shin, Jae Yoon; Wang, Yong-Lei; Yamada, Steven A.; Hung, Samantha T.; Fayer, Michael D.. And the article was published in Journal of Physical Chemistry B in 2019. Electric Literature of C4H6N2 The author mentioned the following in the article:

The dynamics of imidazole (IM) and 1-methylimidazole (1-MeIM) in the liquid phase at 95 °C were studied by IR polarization selective pump-probe and two-dimensional IR (2D IR) spectroscopies. The two mols. are very similar structurally except that IM can be simultaneously a hydrogen bond donor and acceptor and therefore forms extended hydrogen-bonded networks. The broader IR absorption spectrum and a shorter vibrational lifetime of the vibrational probe, selenocyanate anion (SeCN-), in IM vs 1-MeIM indicate that stronger hydrogen bonding exists between SeCN- and IM. Mol. dynamics (MD) simulations support the strong hydrogen bond formation between SeCN- and IM via the HN moiety. SeCN- makes two H-bonds with IM; it is inserted in the IM H-bonded chains rather than being a chain terminator. The strong hydrogen bonding influenced the reorientation dynamics of SeCN- in IM, leading to a more restricted short time angular sampling (wobbling-in-a-cone). The complete orientational diffusion time in IM is 1.7 times slower than in 1-MeIM, but the slow down is less than expected, considering the 3-fold larger viscosity of IM. The jump reorientation mechanism accounts for the anomalously fast orientational relaxation in IM, and the MD simulations determined the average jump angle of the probe between hydrogen bonding sites. Spectral diffusion time constants obtained from the 2D IR experiments are only modestly slower in IM than in 1-MeIM in spite of the significant increase in viscosity. The results indicate that the spectral diffusion sensed by the SeCN- has IM hydrogen bond dynamics contributions not present in 1-MeIM.

In 2019,Journal of Applied Polymer Science included an article by Huo, Pengfei; Xun, Zhiyu; Ni, Shoupeng; Liu, Yang; Wang, Guibin; Gu, Jiyou. COA of Formula: C4H6N2. The article was titled 《Crosslinked quaternized poly(arylene ether sulfone) copolymer membrane applied in an electric double-layer capacitor for high energy density》. The information in the text is summarized as follows:

The low energy d. of supercapacitors, especially supercapacitors based on aqueous electrolytes, is the main factor limiting their application, and the energy d. is closely related to the operating potential window of the supercapacitor. The polymer electrolyte is the main contributor to the safe operation and good ion conductivity of the supercapacitor. In this study, a crosslinked quaternized poly(arylene ether sulfone) (PAES) membrane was prepared via crosslinking during membrane formation with a thermal-only treatment and applied in an elec. double-layer capacitor (EDLC). The pre-prepared PAES membrane formed a polymer electrolyte with 1 mol/L Li2SO4 and was then fabricated into an EDLC single cell. The properties of both the membrane and ELDC were investigated. The preferred cPAES-N-0.2 polymer electrolyte showed an ionic conductivity of 1.18 mS/cm. The optimized EDLC exhibited a single-electrode gravimetric capacitance of 104.92 F/g at a c.d. of 1.0 A/g and a high operating potential window (1.5 V); it, thereby, achieved a high energy d. of 8.20 W h/kg. The EDLC also exhibited excellent cycling properties over 3000 charge-discharge cycles. The crosslinked structures promoted the tensile strength and thermal stability of the PAES membranes; this was accompanied by a slight decrease in the ionic conductivity In the part of experimental materials, we found many familiar compounds, such as 1-Methyl-1H-imidazole(cas: 616-47-7COA of Formula: C4H6N2)
