On September 10, 2020, Payami, Elmira; Teimuri-Mofrad, Reza; Ahadzadeh, Iraj; Mohammadi, Reza published an article.Quality Control of 3-Acetyldihydrofuran-2(3H)-one The title of the article was A novel composite electrode material derived from bisferrocenyl-functionalized GO and PANI for high performance supercapacitor. And the article contained the following:

A novel bisferrocenyl based epoxy compound was synthesized to be used for further surface modification of graphene oxide (GO). GO surface was firstly modified with ethylenediamine (EDA) as an amine linker and then bisferrocenyl based epoxy compound was covalently grafted to the GO surface through the epoxide ring opening reaction. Afterwards, polyaniline (PANI) nanofibers were phys. adsorbed onto the surface of the modified GO to obtain a potentially high-performance nanocomposite for battery-type supercapacitor applications. The surface modification, crystalline structure, morphol., composition, and microstructure of the synthesized nanocomposites were further studied using FTIR spectroscopy (FTIR), XRD, field emission SEM (FESEM), energy dispersive X-ray (EDX) and N2 adsorption/desorption analyses, resp. Also, the electrochem. behavior of the synthesized nanocomposites was studied by electrochem. methods of cyclic voltammetry (CV), electrochem. impedance spectroscopy (EIS), galvanostatic charge-discharge measurement (GCD). The final nanocomposite electrode exhibited a charge storage capacity of 272 mAh g-1, and capacity retention of 89% over 3000 CV cycles. A high energy d. of 69.3 Wh kg-1 and high power d. of 6171 W kg-1 were achieved in a sym. two-electrode configuration. The experimental process involved the reaction of 3-Acetyldihydrofuran-2(3H)-one(cas: 517-23-7).Quality Control of 3-Acetyldihydrofuran-2(3H)-one

On October 6, 2021, Liu, Zhimeng; Fang, Chen; He, Xin; Zhao, Yangzhi; Xu, Hualiang; Lei, Jingxin; Liu, Gao published an article.Product Details of 517-23-7 The title of the article was In Situ-Formed Novel Elastic Network Binder for a Silicon Anode in Lithium-Ion Batteries. And the article contained the following:

High energy d. lithium-ion batteries with preferable cycling stability are critical for the development of all-elec. vehicles. Silicon (Si) has demonstrated a remarkable potential for application as anode materials due to its superior capacity performance and worldwide abundance. However, Si intrinsically undergoes substantial volume fluctuation during repeated lithiation/delithiation processes, which pulverizes the Si particles and undermines the integrity of the electrode structures, thus resulting in frustrating cycling stability. We developed a polymer binder with a highly stretchable and elastic network structure that can accommodate volume variation of Si. This was realized by an in situ crosslinking of polyacrylic acid (PAA) with isocyanate-terminated polyurethane oligomers that consist of polyethylene glycol (PEG) chains and 2-ureido-4-pyrimidinone (UPy) moieties through the reaction between isocyanate and carboxyl during the electrode preparation process. In this binder network, PAA could strongly adhere to the Si particles by forming hydrogen bonding with the surface hydroxyl groups. The PEG chains induce the flexibility of the polymer network, while the UPy moieties endow the polymer network with desirable mech. strength through the formation of reversible and strong quadruple H-bonding cross-linkers. This binder not only can sufficiently accommodate the volume change of Si but can also provide a strong mech. support to effectively sustain the integrity for the Si anode, consequently enhancing cycle stability and rate performance. The experimental process involved the reaction of 3-Acetyldihydrofuran-2(3H)-one(cas: 517-23-7).Product Details of 517-23-7

On July 31, 2020, Burcu Guerdere, Meliha; Aydin, Ali; Yencilek, Belkiz; Ertuerk, Fatih; Oezbek, Oguz; Erkan, Sultan; Budak, Yakup; Ceylan, Mustafa published an article.Computed Properties of 517-23-7 The title of the article was Synthesis, Antiproliferative and Cytotoxic Activities, DNA Binding Features and Molecular Docking Study of Novel Enamine Derivatives. And the article contained the following:

Novel enamine derivatives were synthesized from the reaction of lactone and chalcones and their antiproliferative and cytotoxic activities against six cancer cell lines (e. g., HeLa, HT29, A549, MCF7, PC3 and Hep3B) and one normal cell lines (e. g., FL) were investigated along with their mode of interactions with CT-DNA. Most of the enamine derivatives with IC50 values of 86-168 μM demonstrated much stronger antiproliferative activity than the starting mols. against the cancer cells. While, among the enamine derivatives, four compounds displayed higher cytotoxic potency than the control drugs (5-fluorouracil and cisplatin) against the Hep3B cell lines, these compounds did not exhibit any significant toxicity against normal cells, FL. The UV/VIS spectral data suggest that eight compounds cause hypochromism with a slight bathochromic shift (∼6 nm), indicating that they bind to the DNA by way of an intercalative or minor groove binding mode. The binding constants of the compounds are in the range of 0.1×103 M-1-2.3×104 M-1. The antiproliferative activity of studied enamine derivatives could possibly be due to their DNA binding as well as their cytotoxic properties. In addition to these assays, the chalcones and enamine derivatives were investigated by mol. docking to calculate the synergistic effect of antiproliferative activities against six human cancer cell lines. The experimental process involved the reaction of 3-Acetyldihydrofuran-2(3H)-one(cas: 517-23-7).Computed Properties of 517-23-7

And the article contained the following:

Herein, the direct α-sulfenylation of a series of β-dicarbonyl, β-ketophosphonate, and β-ketonitrile compounds, mediated by sulfonium salts has been described. Traditionally, sulfonium salts which are synthesized by activation of dialkylsulfoxides serve as oxidizing agents or precursors of sulfur ylide. In this transformation, sulfonium salts as readily prepared and operationally simple sulfenylation reagents firstly achieved alkylsulfenylation of various activated C(sp3)-H bonds with the formation of tetra-substituted carbon center. Thus, e.g., sulfenylation of Me 2-oxocyclopentanecarboxylate with DMSO in presence of AcCl as activator and NaSbF6 in MeCN afforded I (79%).
