Fast-Charging Lithium-Sulfur Batteries Enabled via Lean Binder Content

Next-generation energy storage devices such as lithium-sulfur batteries (LSBs) face several challenges including fast charging and high-power delivery. Thus, it is necessary to improve the stability of the electrodes with efficient electrochemical system. In this work, a durable sulfur cathode even at high rates is enabled via lean binder content. The binder consists of a chitosan cross-linked with a carboxylated nitrile-butadiene rubber (XNBR), which exhibits high affinity toward lithium polysulfide along with robust mechanical properties because of the synergistic effect of the polar chitosan and the elastomeric XNBR. Despite using extremely small content of binder (3 wt%), the LSB shows a highly stable long-term cycling performance with capacity retention decay values of 0.026% and 0.029% after 500 cycles at 5 and 10 C. Moreover, the cell shows an outstanding specific capacity of 228 mAh g(-1) at an ultrahigh charge-discharge rate of 20C. This approach may significantly improve the design of the sulfur cathode and pave a facile way to fabricate commercially viable next-generation energy storage devices.

Computational exploration of the 1,3-dipolar cycloaddition reaction of 7-isopropylidenebenzonorbornadiene with nitrile oxide and cyclic nitrone derivatives

The synthesis of isoxazolidine and isoxazole derivatives, versatile building blocks for the construction of a wide range of complex heterocyclic architectures in synthetic organic and medicinal chemistry, is efficiently achieved via the 1,3-dipolar cycloaddition reaction (1,3-DC). Herein, we report an extensive theoretical study on the peri-, regio-, stereo, and enantio-selectivities of 1,3-DC of 7-isopropylidenebenzonorbornadiene with nitrile oxide and cyclic nitrone derivatives using density functional theory calculations. Acetophenone-substituted nitrile oxide periselectively adds across the endocyclic olefinic bond of the dipolarophile to furnish the exo-cycloadduct as the major product, a reaction that has a rate constant of 1.88 x 10(9) s(-1). The endo approach of this periselective path is the closest competing pathway with a rate constant of 4.59 x 10(7) s(-1). Different substituents on the nitrile oxide do not affect the peri- and stereo-selectivity of the reaction. Diethyl ether solvation has no substantial effect on the energetic patterns observed in the gas phase computation. Also, we report a novel 1,3-DC between cyclic nitrone derivatives and 7-isopropylidenebenzonorbornadiene as an efficient way to generate isoxazolidine derivatives. Even though the reactions of the cyclic nitrone derivatives have slightly higher activation barriers than the acyclic nitrile oxide derivatives, the former is more enantioselective than the latter. Whereas electron-donating groups (EDGs) on the cyclic nitrone favor the formation of the exo-cycloadduct, electron-withdrawing groups (EWGs) favor the formation of the endo-cycloadduct. Both 1,3-dipoles add across the dipolarophile via a concerted asynchronous mechanism.

Detection of CH3C3N in Titan’s Atmosphere

Titan harbors a dense, organic-rich atmosphere primarily composed of N-2 and CH4, with lesser amounts of hydrocarbons and nitrogen-bearing species. As a result of high-sensitivity observations by the Atacama Large Millimeter/submillimeter Array (ALMA) in Band 6 (similar to 230-272 GHz), we obtained the first spectroscopic detection of CH3C3N (methylcyanoacetylene or cyanopropyne) in Titan’s atmosphere through the observation of seven transitions in the J = 64 -> 63 and J = 62 -> 61 rotational bands. The presence of CH3C3N on Titan was suggested by the Cassini Ion and Neutral Mass Spectrometer detection of its protonated form: C4H3NH+, but the atmospheric abundance of the associated (deprotonated) neutral product is not well constrained due to the lack of appropriate laboratory reaction data. Here, we derive the column density of CH3C3N to be (3.8-5.7).x.10(12) cm(-2) based on radiative transfer models sensitive to altitudes above 400 km Titan’s middle atmosphere. When compared with laboratory and photochemical model results, the detection of methylcyanoacetylene provides important constraints for the determination of the associated production pathways (such as those involving CN, CCN, and hydrocarbons), and reaction rate coefficients. These results also further demonstrate the importance of ALMA and (sub)millimeter spectroscopy for future investigations of Titan’s organic inventory and atmospheric chemistry, as CH3C3N marks the heaviest polar molecule detected spectroscopically in Titan’s atmosphere to date.

One Pot Synthesis and Antitumor Activity of Isoxazole-Pyrimido[4,5-c]isoquinolines

A number of new isoxazole coupled pyrimido[4,5-c]isoquinolines has been synthesized in good to excellent yields by the one pot method. The Cu(I)-catalyzed cycloaddition reaction between the terminal alkyne 4 and various aldehydes has led to nitrile oxides. The in vitro study of antitumor activity of the products has indicated three of those to be potent anticancer (MCF-7) agents with IC50 values close to that of the standard drug. Molecular docking studies have also been conducted to complement the experimental results.

Reactivity of a magnesium diboranate with organic nitriles

A series of complexes generated through reactions of the beta-diketiminato magnesium diboranate species, [(BDI)Mg{(n-Bu)pinB-Bpin}] (BDI = HC{(Me)CNDipp}(2); Dipp = 2,6-di-iso-propylphenyl), and a variety of organic nitriles are reported. Although, in every case, the diboranate anion acts as a surrogate source of the {Bpin} nucleophile, resulting in B-C bond formation at the electrophilic sp-hydridised nitrile carbon, the resultant compounds display a variable propensity to undergo subsequent reaction with additional nitrile equivalents. This behaviour is rationalised to be a consequence of substituent-dependent modulation in the basicity and resultant electrophilicity of magnesium-coordinated nitrile intermediates.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 19472-74-3 is helpful to your research. Product Details of 19472-74-3.

A Facile Transition Metal-Free Ionic Liquid [BMIM]OH Mediated Regio- and Stereoselective Hydrocarboxylation of Alkynylnitriles

A straightforward access to 3-trifluoromethyl-1H-indazoles via (3+2)-cycloaddition of arynes with nitrile imines derived from trifluoroacetonitrile

In situ generated arynes react with nitrile imines derived from trifluoroacetonitrile at 0 degrees C in THE solutions yielding 3-trifluoromethyl-1H-indazole derivatives as the only intermolecular products. The reaction corresponds the expected (3 + 2)-cycloadditions which belong to the Type III (inverse-electron-demand) of Sustmann’s classification.

8-cyanobenzothiazinone analogs with potent antitubercular activity

8-Nitrobenzothiazinones (BTZs) exemplified by macozinone are a new class of antitubercular agents with exceptionally potent activity. The aryl nitro group has been considered indispensable for activity since this is bioactivated within mycobacteria by the flavoenzyme DprE1 to a reactive nitroso metabolite that covalently labels Cys387. However, the aryl nitro group is a potential liability with regards to safety, stability, and resistance. In this paper, we introduced a nitrile as a bioisosteric replacement of the nitro group, which we hypothesize can maintain a similar covalent mechanism of inhibition, but mitigate against the aforementioned concerns. 8-cyanobenzothiazinone 1d displayed potent antitubercular activity with an MIC of 130 nM and had an improved volume of distribution in mice that increased the intrinsic half-life by twofold compared to macozinone. Analysis of the C-2 substituent of 1d revealed similar structure-activity relationships as observed for macozinone. Overall, the results confirm the 8-nitro group of benzothiazinones can be successfully replaced with a nitrile to retain useful activity and favorable pharmacokinetic properties. [GRAPHICS] .

Highly concentrated nitrile functionalized disiloxane – LiFSI based non-flammable electrolyte for high energy density Li metal battery

High energy density and safety are key issues of Li metal battery (LMB). A thin Li anode coupling with high voltage/ high capacity cathode (NCM811) can increase the energy density of Lithium batteries. We have developed a fire retar dant disiloxane based highly concentrated electrolyte which makes a coordinated Li+-FSI–Solvent cluster to produce stable interphase on electrodes. This electrolyte shows reduced reactivity towards Li metal anode. The oxidation stability of electrolyte is high (5 V) and also shows less Al corrosion. The synergistic effect of additive makes inorganic ‘LiF’-rich dendrite free interphase. SEM analysis confirms dendrite free surface morphology. A Li metal full cell is fabricated with thin Li anode (20 mu m, 4.12 mAh/cm(2)) and NCM811 cathode with moderate active material loading (1.1 mAh/cm(2)), providing a high energy density of 614 Wh kg(-1) (based on total weight of anode and cathode excluding current collectors).
