An electrolyte for a lithium secondary battery includes: a lithium salt; a non-aqueous organic solvent; and the additive represented by Formula 1. A lithium secondary battery includes: a cathode; an anode; and the electrolyte including the additive represented by Formula 1.
A conformational analysis of the methanesulfonamide-N,N′-1,2-ethanediylbis (msen) was performed by using vibrational and NMR spectroscopies as well as theoretical computations. The possible stable conformers of msen on its potential energy surface were investigated by semi-empirical PM5 method and appropriate structures were defined with B3LYP hybrid density functional theory (DFT) method along with
通过使用振动光谱和NMR光谱以及理论计算,对甲磺酰胺-N,N'-1,2-乙二基双(msen)进行了构象分析。通过半经验PM5方法研究了msen在其势能表面上可能的稳定构象,并通过B3LYP混合密度泛函理论(DFT)方法以及不同大小和类型的基集定义了合适的结构。DFT计算的结果发现了六个不同的旋转异构体。两个异构体,称为反式-笨拙+ -eclipsed,synperiplanar(TTG + -e,双)和反式笨拙+ -gauche - -staggered,antiplanar(TG +克--s,anti)在振动光谱分析中被考虑。固态测量了msen的红外光谱(4000–30 cm -1)和拉曼光谱(4000–60 cm -1)。为了完整分配振动光谱,进行了B3LYP / 6311-G(d,p)理论水平的DFT计算,并结合了标定量子力学力场(SQMFF)方法。此外,在理论水平的B3LYP / 6-311
Quantitative structure–activity relationships studies for prediction of antimicrobial activity of synthesized disulfonamide derivatives
A new series of disulfonamides were synthesized and assayed as antimicrobial agents against Staphylococcus aureus, Bacillus cereus, and Escherichia coli. The quantitative structure-activity relationship analysis (QSAR) was applied to find out the correlation between experimentally evaluated antimicrobial activities with various parameters of the compounds using stepwise multiple liner regression method. The QSAR analysis revealed that the third-order average connectivity index ((3)chi(A)) was found to have negative correlation. The best QSAR models were further validated by leave-one-out method of cross-validation.
