Three different organic solvents (dimethylacetamide (DMAc), dimethylformamide (DMF), and dimethyl sulfoxide (DMSO)) were used to improve the solubility of LiNO 3 in a standard carbonate-based electrolyte with lithium difluoro(oxalato)borate (LiDFOB) as salt. Together, LiDFOB organic-solvent solubilized preferentially reduce on surface silicon-containing anodes create an SEI rich oxalates, nitra...

The surface tension at the liquid–air interface of eight binary mixtures formed by N,N-dimethylacetamide and n-alkanols (from methanol to 1-pentanol) or 2-alkanols 2-propanol 2-pentanol) was studied three different temperatures (283.15, 298.15, 313.15 K) a pressure 0.1 MPa. Surface deviations were also calculated. Moreover, excess molar enthalpies for all these measured T = 298.15 K Both deviat...

This paper presents the results of a study random copolyethersulfone sulfides based on 4,4-dichlorodiphenylsulfone, 1,1-dichloro-2,2-di(4-hydroxyphenyl)ethylene, and sodium sulfide. The synthesis with different ratios polyethersulfone polyphenylenesulfone sulfide units was carried out by high-temperature polycondensation reaction nucleophilic substitution in N,N-dimethylacetamide medium using p...

Discuss here is a kind of novel Dy-based Metal Organic Frameworks (MOF) material, ((Dy(H2O)(PBA) (SO4))(DMA)2(H2NC2H6))n(1 H2PBA=4-Hydroxybenzoic acid; the DMA=N,N-Dimethylacetamide), from the solvothermal synthesis conditions and using sulfuric acid as the PH controller and template. The X-ray studies shown that 1 is a 3D two-fold interpenetrated MOF built up from 1D-Dy (III) ribbon chains and...

A water stable porous 3D metal-organic framework, [Cu3L2(μ3-OH)2(μ2-H2O)]·2DMA (1, mother crystal, H2L = 2,2'-dinitrobiphenyl-4,4'-dicarboxylic acid, DMA = N,N-dimethylacetamide), shows unprecedented irreversible solvent-induced substitutions of bridging aqua ligands and guest-exchanges in single-crystal-to-single-crystal (SCSC) transformations at room temperature (RT), producing quantitatively...

A range of chemistries were explored for the efficient covalent conjugation of DNA to poly(N-isopropylacrylamide) (poly(NIPAM)) in organic solvents. Amide coupling and thiol-ene Michael addition were found to be ineffective for the synthesis of the desired products. However, the inverse electron-demand Diels-Alder (DAinv) reaction between tetrazine (Tz) and norbornene (Nb) was found to give DNA...

Cavitand 1 possesses four 2,2'-bipyridyl pillars on its upper rim that encapsulates small guests, such as nitromethane, acetonitrile, methyl acetate, ethyl acetate, and N-methylacetamide, into a deep cavity to form host-guest complexes in a 1:1 ratio. Nitroethane, N,N-dimethylformamide, and N,N-dimethylacetamide were not bound in this manner. A guest-binding study and molecular mechanics calcul...
