| 2 | Effects of anions and alkyl chain length of imidazolium-based ionic liquids at the Au(111)surface on interfacial structure:a first-principles study显示文摘The interfacial structure and adsorption mechanism of imidazolium-based ionic liquids(ILs)on Au(111)surface were investigated via first-principles calculation.Electron density analysis and Bader charge analysis were used to explore the electronic structure of Au(111)-ILs interface.Computations show that the alkyl chain length and anions play a significant role in designing Au(111)-ILs interfacial structure.On the one hand,the stability of interface and adsorption energy tend to be enhanced as the alkyl chain length increases.It attributes to the methylene group of alkyl chain which could easily anchor on the gold interface.On the other hand,the difference in anions makes the adsorption behavior quite different.The adsorption energy follows the order:[C_(n)mim][Br]>[C_(n)mim][Cl]>[Cnmim][TFSA]>[C_(n)mim][OAc]>[C_(n)mim][PF6]>[C_(n)mim][BF_(4)].The nonfluorinated ILs(containing Br,Cl,and O atoms of anions)always have a drastic charge transfer among gold-ILs interface.However,the larger van der Waals(vdWs)volumes of the fluorinated anions have a more diffused electron density which lead to the relatively weak interaction.To sum up,a detailed and systematic investigation of the variation of anions and alkyl chain length of ILs which will affect the interfacial structure is fully studied.The above study could be helpful to understand electrode-electrolyte microscopic interface and design of functional materials for energy storage. | Chunlei Wei Kun Jiang Timing Fang Xiaomin Liu | 2021 | Green Chemical Engineering2021，2，4： | 0 |
| 3 | Investigation on drawing process of Bi-2223/Ag wires using racetrack-type dies:Simulation and experiments显示文摘The traditional rolling process of Bi-2223/Ag wires with circular sections is an inhomogeneous process. For the purpose of achieving a uniform filaments distribution, a novel technique for round wire through racetrack-type dies during the last several passes of drawing is necessarily brought forward. In order to investigate the processing behaviors of superconducting filaments, a numerical model for the three passes of racetrack drawing was constructed, and subsequently, the optimization of three racetrack-type dies was designed based on the simulation results. Then the three passes of racetrack drawing was applied to fabricate Bi-2223/Ag tape and the density distribution of each filament of the wire was studied by Vickers microhardness. The experimental results showed that the racetrack drawing can obtain dense superconducting filaments, and improve the mechanical properties and critical current of the final tape. | LU YongJin ZENG Pan LEI LiPing QU TiMing FANG Gang SUN JianFeng | 2009 | Science China(Technological Sciences)2009，52，8： | 0 |
