The self-discharge mechanism of LiNi0.4Mn1.6O 4, investigated by electrochemical methods, is mostly attributed to oxidative electrolyte decomposition due to the high lithium (de-)insertion potentials, since the material insertion capacity appears to be fully reversible upon subsequent galvanostatic cycling. A series of 40 different compounds, such as for instance fluorinated ethylene carbonate, 1,3-propane sultone, lithium bis(oxalato)borate (LiBOB), or a variety of ionic liquids, was investigated as suitable electrolyte additives to form a stable LNMO/electrolyte interphase in order to prevent the self-discharge by the continuous oxidative electrolyte decomposition. Among these, only one compound, namely succinic anhydride, revealed to have a beneficial effect on the self-discharge of LNMO based cathodes, while showing an enhanced coulombic efficiency and a decreased capacity loss per cycle. Additionally, the modification of the LNMO particles surface by adding succinic anhydride to the electrolyte was confirmed by performing ex situ SEM and XPS analysis of galvanostatically cycled electrodes.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: Tetrahydrofurans, you can also check out more blogs about4100-80-5

Application of 4971-56-6, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.4971-56-6, Name is Furan-2,4(3H,5H)-dione, molecular formula is C4H4O3. In a Article，once mentioned of 4971-56-6

The present work describes sustainable, catalyst free and bio-oriented multicomponent synthesis of 2-amino-3-cynospiro (5H-indeno[1,2-b]pyran-4,3?-indoline)-2?5,-dione using isatin, malononitrile and 1,3-indandione. This study provides a facile synthesis of indeno-spiro compounds and is further supported with molecular docking, physico-chemical parameter and cytotoxicity study. The synthesized compounds were screened against breast carcinoma cell lines (MCF7, MDA-MB-435) and normal Vero monkey cell lines. Among all the tested compounds, the bromo- and chloro- substituted indeno-fused spirooxindole derivatives (entry B and D) were found to show selective potency against the MDA-MB-435 cancer cell lines exhibiting GI50 value of 1.8 and 2.1 muM respectively. The selected compounds were also screened against the normal Vero monkey cell line, which showed good to excellent selectivity against inhibition of cancer cells. Furthermore, the in vitro confocal microscopy cell imaging of selected compounds showed cellular shrinkage and apoptosis in the cancer cells suggesting that the indeno-fused spirooxindoles can be explored as selective estrogen negative receptors with a safety profile.

A study on the origin of rate enhancement (RE) in the enantioselective heterogeneous catalytic hydrogenation of methyl benzoylformate (MBF), ketopantolactone (KPL) and pyruvic aldehyde dimethyl acetal (PA) under the Orito reaction conditions over Pt catalyst modified with parent cinchona alkaloids, as compared to the unmodified catalyst is presented. The hydrogenations were carried out in continuous-flow fixed-bed reactor system over 20-100 mg Pt/Al2O3 catalyst in 1 mL min-1 flow of toluene/acetic acid 9/1 solvent mixture under 40-80 bar H2 pressure, at 283 or 293 K using 0.044-2 mM modifier concentration and 45 mM substrate concentration. Our results obtained using racemic hydrogenations followed by three changes of the chiral modifier (on the same catalyst) supported the so-called “ligand acceleration” phenomenon in the enantioselective hydrogenation of activated ketones such as MBF, KPL and PA. In our opinion, RE produced by the first modifier added after racemic hydrogenation can also be explained by the purifying effect of the cinchona. REs observed following further exchanges of modifiers are indicative of the intrinsic character of the phenomenon. This research suggested that the origin of enantiodifferentiation and rate enhancement is the same, namely, both may be traced back-probably in different ways-to the role of the intermediate complexes of the hydrogenation, to its formation and transformation, which in turn depends on numerous factors.

As part of an effort to identify novel backups for previously reported pyrazole-based coagulation Factor Xa inhibitors, the pyrazole 5-carboxamide moiety was replaced by 3-(sulfonylamino)-2-piperidone. This led to the identification of a structurally diverse chemotype that was further optimized to incorporate neutral or weakly basic aryl and heteroaryl P1 groups while maintaining good potency versus Factor Xa. Substitution at the sulfonamide nitrogen provided further improvements in potency and as did introduction of alternate P4 moieties.
