Solid electrolyte interphase (SEI)-forming agents such as vinylene carbonate, sulfone, and cyclic sulfate are commonly believed to be film-forming additives in lithium-ion batteries that help to enhance graphite anode stability. However, we find that the film-forming effect and the resultant SEI may not be the only reasons for the enhanced graphite stability. This is because the as-formed SEI cannot inhibit Li+-solvent co-intercalation once the additive is removed from the electrolyte. Instead, we show that the Li+ solvation structure, which is modified by these additives, plays a critical role in achieving reversible Li+ (de)intercalation within graphite. This discovery is confirmed in both carbonate and ether-based electrolytes. We show that the problem of graphite exfoliation caused by Li+-solvent co-intercalation can be mitigated by adding ethene sulfate to tune the Li+ coordination structure. This work brings new insight into the role of additives in electrolytes, expanding the prevailing thinking over the past 2 decades. This finding can guide the design of more versatile electrolytes for advanced rechargeable metal-ion batteries.Vinylene carbonate(cas: 872-36-6HPLC of Formula: 872-36-6) was used in this study.

Nural, Yahya; Ozdemir, Sadin; Yalcin, Mustafa Serkan; Demir, Bunyamin; Atabey, Hasan; Ece, Abdulilah; Seferoglu, Zeynel published their research in ChemistrySelect in 2021. The article was titled 《Synthesis, Biological Evaluation, Molecular Docking, and Acid Dissociation Constant of New Bis-1,2,3-triazole Compounds》.Synthetic Route of C5H6O2 The article contains the following contents:

In this study, new bis-1,2,3-triazole derivatives, N,N’-(1,3-phenylene)bis(2-(4-R-1H-1,2,3-triazol-1-yl)acetamide), were synthesized by copper-catalyzed azide-alkyne cycloaddition click chem. in 84-96% yield. A wide range bioactivity screening was performed to determine DNA cleavage, antioxidant, antibacterial and antifungal activities. All of the synthesized bis-1,2,3-triazoles showed excellent DNA cleavage activity and compound I, bearing 2-bromoethyl moiety as a substituent, was almost degraded all of the plasmid DNA. Mol. docking simulations suggest that the synthesized compounds act as minor groove binders of DNA. The antioxidant activities of the bis-1,2,3-triazoles were determined based on the radical scavenging effect of the stable 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical and iron chelating activity. The compounds exhibited effective iron chelating activity at 200 mg/L while showing a moderate ability to scavenge DPPH radical. The compounds exhibited antibacterial activity with a MIC value in the range of 4-128μg/mL. Compound II, bearing cyclohexylmethyl moiety as substituent, exhibited a broad-spectrum antimicrobial activity (both antibacterial and antifungal). Four different acid dissociation constant (pKa) values of each product were determined potentiometrically in 20% (volume/volume) DMSO-water at 25 +/= 0.1°, at an ionic background of 0.1 mol/L of NaCl using the HYPERQUAD program. In addition to this study using Ethyl propiolate, there are many other studies that have used Ethyl propiolate(cas: 623-47-2Synthetic Route of C5H6O2) was used in this study.

The article was titled 《Phenotype Screening of an Azole-bisindole Chemical Library Identifies URB1483 as a New Antileishmanial Agent Devoid of Toxicity on Human Cells》.Application of 623-47-2 The article contains the following contents:

We report the evaluation of a small library of azole-bisindoles for their antileishmanial potential, in terms of efficacy on Leishmania infantum promastigotes and intracellular amastigotes. Nine compounds showed good activity on L. infantum MHOM/TN/80/IPT1 promastigotes with IC50 values ranging from 4 to 10 μM. These active compounds were also tested on human (THP-1, HEPG2, HaCaT, and human primary fibroblasts) and canine (DH82) cell lines. URB1483 was selected as the best compound, with no quantifiable cytotoxicity in mammalian cells, to test the efficacy on intracellular amastigotes. URB1483 significantly reduced the infection index of both human and canine macrophages with an effect comparable to the clin. used drug pentamidine. URB1483 emerges as a new anti-infective agent with remarkable antileishmanial activity and no cytotoxic effects on human and canine cells.

Computed Properties of C3H2O3In 2019 ,《Copper Silicide Nanowires as Hosts for Amorphous Si Deposition as a Route to Produce High Capacity Lithium-Ion Battery Anodes》 was published in Nano Letters. The article was written by Stokes, Killian; Geaney, Hugh; Sheehan, Martin; Borsa, Dana; Ryan, Kevin M.. The article contains the following contents:

Herein, copper silicide (Cu15Si4) nanowires (NWs) grown in high densities from a metallic Cu substrate are utilized as nanostructured hosts for amorphous silicon (aSi) deposition. The conductive Cu15Si4 NW scaffolds offer an increased surface area, vs. planar substrates, and enable the preparation of high capacity Li-ion anodes consisting of a nanostructured active material. The formation method involves a two-step process, where Cu15Si4 nanowires are synthesized from a Cu substrate via a solvent vapor growth (SVG) approach followed by the plasma-enhanced chem. vapor deposition (PECVD) of aSi. These binder-free anodes are investigated in half-cell (vs. Li-foil) and full-cell (vs. LCO) configurations with discharge capacities greater than 2000 mAh/g retained after 200 cycles (half-cell) and reversible capacities of 1870 mAh/g exhibited after 100 cycles (full-cell). A noteworthy rate capability is also attained where capacities of up to 1367 mAh/g and 1520 mAh/g are exhibited at 5C in half-cell and full-cell configurations, resp., highlighting the active material’s promise for fast charging and high power applications. The anode material is characterized prior to cycling and after 1, 25, and 100 charge/discharge cycles, by SEM (SEM) and transmission electron microscopy (TEM), to track the effects of cycling on the material.

Product Details of 872-36-6In 2020 ,《σ-Bond Migration Assisted Decarboxylative Activation of Vinylene Carbonate in Rh-Catalyzed 4 + 2 Annulation: A Theoretical Study》 was published in Organometallics. The article was written by Shen, Boming; Liu, Song; Zhu, Lei; Zhong, Kangbao; Liu, Fenru; Chen, Haohua; Bai, Ruopeng; Lan, Yu. The article contains the following contents:

As a C2 synthon, vinylene carbonate was used instead of acetylene in transition-metal catalyzed-coupling reactions. The mechanism of the vinylene carbonate activation mode for the Rh(III)-catalyzed 4 + 2 annulation of benzamide and vinylene carbonate reaction is proposed, and it was studied by DFT with the M06 d. functional. The computational results show that the proposed reaction pathway, which includes the insertion of vinylene carbonate into an Rh-C bond, decarboxylation of the seven-membered rhodacycle intermediate, protonation of the ketonate Rh intermediate, deprotonation of the benzamide, and catalyst regeneration, is the most favorable pathway. The 1,2-Rh migration process can assist decarboxylative activation of vinylene carbonate, which is the rate-determining step in the catalytic cycle. The IRC calculation clearly revealed a quasi-synchronized process to directly afford a cyclic ketonate Rh intermediate by the release of CO2.

In 2022,Quant, Maria; Hillers-Bendtsen, Andreas Erbs; Ghasemi, Shima; Erdelyi, Mate; Wang, Zhihang; Muhammad, Lidiya M.; Kann, Nina; Mikkelsen, Kurt V.; Moth-Poulsen, Kasper published an article in Chemical Science. The title of the article was 《Synthesis, characterization and computational evaluation of bicyclooctadienes towards molecular solar thermal energy storage》.Name: Ethyl propiolate The author mentioned the following in the article:

Mol. solar-thermal energy storage (MOST) systems are based on photoswitches that reversibly convert solar energy into chem. energy. In this context, bicyclooctadienes (BODs) undergo a photoinduced transformation to the corresponding higher energy tetracyclooctanes (TCOs), but the photoswitch system has not until now been evaluated for MOST application, due to the short half-life of the TCO form and limited available synthetic methods. The BOD system degrades at higher temperature via a retro-Diels-Alder reaction, which complicates the synthesis of the compounds We here report a cross-coupling reaction strategy that enables an efficient synthesis of a series of 4 new BOD compounds We show that the BODs were able to switch to the corresponding tetracyclooctanes (TCOs) in a reversible way and can be cycled 645 times with only 0.01% degradation Half-lives of the TCOs were measured, and we illustrate how the half-life could be engineered from seconds to minutes by mol. structure design. A d. functional theory (DFT) based modeling framework was developed to access absorption spectra, thermal half-lives, and storage energies which were calculated to be 143-153 kJ mol-1 (0.47-0.51 MJ kg-1), up to 76% higher than for the corresponding norbornadiene. The combined computational and exptl. findings provide a reliable way of designing future BOD/TCO systems with tailored properties. The results came from multiple reactions, including the reaction of Ethyl propiolate(cas: 623-47-2Name: Ethyl propiolate)

The article was titled 《Synthesis of (2H)-Indazoles and Dihydrocinnolinones through Annulation of Azobenzenes with Vinylene Carbonate under Rh(III) Catalysis》, and you may find the article in Organic Letters.Application In Synthesis of Vinylene carbonate The information in the text is summarized as follows:

The Rh(III)-catalyzed C-H functionalization and subsequent intramol. cyclization between azobenzenes and vinylene carbonate is described herein. Depending on the electronic property of azobenzenes, this transformation results in the formation of (2H)-indazoles or dihydrocinnolin-4-ones through the generation of ortho-alkylated azo-intermediates followed by decarboxylation. Surprisingly, vinylene carbonate acts as an acetaldehyde or acetyl surrogate to enable the [4 + 1] or [4 + 2] annulation reaction. This transformation is characterized by its mild reaction conditions, simplicity, and excellent functional group compatibility.
