The author of 《Anode interfacial layer formation via reductive ethyl detaching of organic iodide in lithium-oxygen batteries》 were Zhang, Xiao-Ping; Sun, Yi-Yang; Sun, Zhuang; Yang, Chu-Shu; Zhang, Tao. And the article was published in Nature Communications in 2019. Electric Literature of C3H9IOS The author mentioned the following in the article:

As soluble catalysts, redox mediators can reduce the high charging overpotential of lithium-oxygen batteries by providing sufficient liquid-solid interface for lithium peroxide decomposition However, the redox mediators usually introduce undesirable reactions. In particular, the so-called “”shuttle effect”” leads to the loss of both the redox mediators and elec. energy efficiency. In this study, an organic compound, triethylsulfonium iodide, is found to act bifunctionally as both a redox mediator and a solid electrolyte interphase-forming agent for lithium-oxygen batteries. During charging, the organic iodide exhibits comparable lithium peroxide-oxidizing capability with inorganic iodides. Meanwhile, it in situ generates an interfacial layer on lithium anode via reductive Et detaching and the subsequent oxidation This layer prevents the lithium anode from reacting with the redox mediators and allows efficient lithium-ion transfer leading to dendrite-free lithium anode. Significantly improved cycling performance has been achieved by the bifunctional organic iodide redox mediator. In the part of experimental materials, we found many familiar compounds, such as Trimethylsulfoxonium iodide(cas: 1774-47-6Electric Literature of C3H9IOS)

The title of the article was 《Additive scheme of solvation enthalpy for halogenated aliphatic hydrocarbons at 298.15 K.》.Recommanded Product: 624-73-7 The author mentioned the following in the article:

In this work, an additive scheme for the estimation of solvation enthalpy of halogenated aliphatic hydrocarbons in n-heptane was developed. The proposed structural fragments for halogen group contributions are dependent on the nature of neighboring atoms. A linear relationship between solvation and vaporization enthalpy at 298.15 K for mono- and di-α,ω-halogen aliphatic compounds was found. These relationships can be used for the quick estimation of standard vaporization and solution enthalpies at 298.15 K. Proposed approaches for estimation of solvation, solution and vaporization enthalpies at 298.15 K were verified by conventional methods. In most cases, absolute deviations between exptl. and estimated values for halogenated aliphatic hydrocarbons do not exceed 1-2 kJ mol-1.
