Effective Interface Defect Passivation via Employing 1-Methylbenzimidazole for Highly Efficient and Stable Perovskite Solar Cells was written by Zheng, Haiying;Liu, Guozhen;Wu, Weiwei;Xu, Huifen;Pan, Xu. And the article was included in ChemSusChem in 2021.Computed Properties of C8H8N2 This article mentions the following:

Although the power conversion efficiencies (PCEs) of perovskite solar cells (PSCs) have made great progress, the surface and interface defects still affect their PCE and stability and hinder the commercialization. To overcome this problem, 1-methylimidazole (1-MIm) and 1-methylbenzimidazole (1-MBIm) were used as the interfacial passivation agents to passivate the defects at surface and interface. The results indicated that, in contrast to 1-MIm, 1-MBIm displayed a stronger Lewis coordination interaction with the uncoordinated Pb²⁺ to reduce the non-radiative recombination and also effectively improved the charge transfer capacity of perovskite films due to its strong Π-Π conjugate interaction, resulting in the better photovoltaic performance. As a result, the PCE of the champion 1-MBIm PSC was improved from 19.48 (pristine) to 21.22 % with a dramatically enhanced open-circuit voltage (V_oc=1.15 V). More importantly, a significant improvement in long-term stability was achieved for 1-MBIm perovskite devices, which was attributed to the high-quality perovskite film caused by the strong passivation effect of 1-MBIm and the hydrogen bond with water mols. The results offers an efficient and facile strategy by interface engineering to fabricate high-performance and stable PSCs for com. application. In the experiment, the researchers used many compounds, for example, 1-Methylbenzimidazole (cas: 1632-83-3Computed Properties of C8H8N2).

Influence of Ionic Liquids on the Viscoelastic Properties of Crude Oil Emulsions was written by Alves, Douglas;Lourenco, Everton;Franceschi, Elton;Santos, Alexandre F.;Santana, Cesar Costapinto;Borges, Gustavo;Dariva, Claudio. And the article was included in Energy & Fuels in 2017.Formula: C18H31F6N3O4S2 This article mentions the following:

Thermochem. treatments are traditionally employed to perform the separation between the oil and water phases in the petroleum industry. The chem. agents have the function of reducing the barrier rigidity formed by natural surfactants present in the emulsion, thus favoring destabilization. The main objective of this study was to analyze the viscoelastic properties of samples composed of water and a crude oil with the addition of distinct ionic liquids The methodol. used to obtain the interfacial properties was the pedant drop technique. The results showed that the addition of the ionic liquids induced a reduction in the interfacial elasticity and an increase in the compressibility of interfacial films. It was also observed that an enhancement in the alkyl chain length has a pos. effect on changing the interfacial properties. The ionic liquid with the highest alkyl chain length investigated ([C₁₂min]⁺[NTf₂]^–) showed the ability to produce the more elastic films for the crude oil investigated.

In this paper, the effect of final pyrolysis temperature on the yield of products from the pyrolysis of sewage sludge was studied. The light fraction from sludge pyrolysis oil was analyzed. The fundamental properties of the pyrolysis residues were also investigated briefly. The results showed that when the final pyrolysis temperature was between 450 °C to 500°C, the yield of liquid product was favorable. With the increase of final pyrolysis temperature, the decreasing trend of pyrolysis residue was similar to the increasing trend of liquid product. Both of them were steep when the temperature was under 450°C and mild when the temperature was higher than 450°C. Meanwhile the uncondensed gas increased smoothly with the increase of final pyrolysis temperature The light fractions of pyrolysis oil obtained at 450°C was mainly consisted of alkanes, alkenes, nitriles and nitrogen-containing heterocyclic compounds as well as MAHs etc. Among them, the concentration of toluene, 4-methyl-phenol, 1-methyl-2, 5-pyrrolidinedione, pyridine, 1-dodecene and pentadecane etc. were significant. The pyrolysis residues of sewage sludge contained low carbon and high ash. However, they still possessed some volatile content. With the increase of final pyrolysis temperature, the surface of pyrolysis residue became more and more looser and rougher. The residue obtained at 450°C exhibited highest pore volume Nevertheless, the residue obtained at 500°C owned maximum sp. surface area in respect that it possessed highest number of micropores.

Adsorption and Tribochemical Factors Affecting the Lubrication of Silicon-Based Materials by (Fluorinated) Ionic Liquids was written by Arcifa, Andrea;Rossi, Antonella;Spencer, Nicholas D.. And the article was included in Journal of Physical Chemistry C in 2017.Application In Synthesis of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

The tribol. behavior of a silica/silicon tribopair lubricated with anhydrous fluorinated ionic liquids was investigated by pin-on-disk tribometry. A first series of tests was designed to detect the onset of surface damage as a function of sliding speed. 1-ethyl-, 1-hexyl-, and 1-dodecyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([EMIM] TFSI, [HMIM] TFSI, and [DDMIM] TFSI, resp.), and 1-ethyl-3-methylimidazolium tris(perfluoroethyl)trifluorophosphate ([EMIM] FAP) were selected as lubricants. Elastohydrodynamic lubrication (EHL) predictive formulas for min. film thickness (h_0 EHL) were used to estimate the value of the critical h_0 EHL at the transition to mixed lubrication, which was identified on the basis of the variations observed in friction upon decreasing the sliding speed. Taking into account the composite roughness of the counterparts (R_q ∼ 1.1 nm), the differences in the critical values of h_0 EHL measured for the various ILs are suggested to reflect changes in the interfacial structure of the confined ILs. In particular, the possible effects associated with the alkyl chain attached to the imidazolium cation or with the type of anion are discussed on the basis of models of the IL-solid interface presented in the recent literature. The second part of the investigation focuses on the tribol. behavior observed with a SiO₂/Si tribopair lubricated with 1-ethyl- and 1-hexyl-3-methylimidazolium-based bis(trifluoromethylsulfonyl)imide ILs under boundary conditions. Tests were carried out under conditions that prevent fluid-film lubrication, so as to allow the study of the boundary-lubrication regime over an extended range of speed. The mechanism of wear was investigated on the basis of a chem., structural, and topog. anal. of the worn surfaces. The prevailing mode of surface damage is described on the basis of a comparison with results previously obtained in tests of other imidazolium-based ILs as lubricants for the same tribopair. The new results revealed some further important details on the relationship between the chem. structure of the IL and the wear mechanism of the investigated tribopair. In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Application In Synthesis of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide).

Highly efficient gel electrolytes by end group modified PEG-based ABA triblock copolymers for quasi-solid-state dye-sensitized solar cells was written by Masud;Kim, Kyeong Min;Kim, Hwan Kyu. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2021.Recommanded Product: 1-Methylbenzimidazole This article mentions the following:

To get highly efficient quasi-solid-state dye-sensitized solar cells (QSS-DSSCs) with long-term stability using polymer gel electrolytes (PGEs), well-defined ABA triblock copolymers ([Poly(Me methacrylate)]₂-block-poly(ethylene glycol)) with different end functionality and components of I^–/I^–₃ liquid electrolytes (LEs) are studied and optimized for the fabrication of PGE-based QSS-DSSCs. Triblock copolymers are synthesized in a one-step reaction using bifunctional PEG-macro chain transfer agent (MCTA) by reversible addition-fragmentation chain transfer (RAFT) polymerization Due to the high reactivity and toxicity of sulfur-containing trithiocarbonate end groups, ABA triblock copolymers prepared from RAFT polymerization are further modified to sulfur-free 2-methylpropionitrile and 4-cyanopentanoic acid end functional triblock copolymers by radical-induced exchange reactions. Dodecyl trithiocarbonate end functional PEG-MCTA and triblock copolymers absorb UV-light in the region of 260-380 nm, whereas sulfur-free carboxylic acid and 2-methylpropionitrile end functional polymers do not absorb in that UV-light region. Among three different end functional polymers, the carboxylic acid end functional triblock copolymer has the highest thermal stability. Based on electrochem. parameters, photovoltaic performance, and long-term stability, 1,2-dimethyl-3-propylimidazolium iodide (DMPII) ionic liquid and 4-tert-butylpyridine (TBP) additive containing acetonitrile-based I^–/I^–₃ LEs are effective for PGEs. The highest power conversion efficiency (PCE) for QSS-DSSCs achieved under simulated 1-sun illumination is up to 10.34%, which is comparable with the highest PCE of 10.39% for LE-DSSCs. Considering the high reactivity, thermal stability, UV-absorption, and the toxicity of the trithiocarbonate end group, the SGT-643-C triblock copolymer with carboxylic acid end group can be a promising candidate as a sulfur-free polymeric matrix for gel electrolytes of QSS-DSSCs.

Stability of Titania Nanomaterials Dispersed in Aqueous Solutions of Ionic Liquids of Different Alkyl Chain Lengths was written by Rouster, Paul;Pavlovic, Marko;Cao, Tianchi;Katana, Bojana;Szilagyi, Istvan. And the article was included in Journal of Physical Chemistry C in 2019.SDS of cas: 35487-17-3 This article mentions the following:

Charging and aggregation of titania nanosheets (TNS) and spherical titania nanoparticles (TNP) were studied in aqueous solutions of ionic liquids The pH and the length of the alkyl chain of the IL cations [1-methylimidazolium (MIM⁺), 1-ethyl-3-methylimidazolium (EMIM⁺), and 1-butyl-3-methylimidazolium (BMIM⁺)] were systematically varied in the experiments No detectable interaction was observed between the IL cations and the pos. charged TNS or TNP surfaces at low pH, where the imidazolium derivatives are the co-ions. For the neg. charged titania nano-objects, significant adsorption of MIM⁺ and EMIM⁺ took place, leading to charge neutralization and overcharging at appropriate concentrations The BMIM⁺ behaved like a simple salt constituent causing charge screening. For both TNS and TNP, the MIM⁺ < EMIM⁺ < BMIM⁺ counterion order was obtained in the critical coagulation concentrations, indicating that MIM⁺ was the most effective in destabilization of the dispersions. The major interparticle forces were of electrostatic origin; however, viscous stabilization was also observed at high IL concentrations The same aggregation mechanism and charging behavior were found for the titania nano-objects irresp. of their shape. The results shed light on the hydrophilic nature of the surface of the TNS and TNP of neg. charge, in contrast to earlier findings with hydrophobic colloidal particles, where the increasing alkyl chain length gave rise to higher destabilization power. The charging properties were governed by specific adsorption of the IL constituents, while the major interparticle forces were qual. well-predicted by the Derjaguin, Landau, Verwey, and Overbeek theory.
