Ionic Liquid Gating Induced Protonation of Electron-Doped Cuprate Superconductors

“…Similar observation was obtained in the EDLT of NdBa 2 Cu 3 O 7 . On the electron-doped side, a very recent study on Pr 2 CuO 4 showed that the gating mechanism can indeed cross from a purely electron-doping scheme in the positive gating ,, to the filling of oxygen vacancies in the negative gating . In general, these studies focus exclusively on oxygen ions/vacancies, leaving the possible involvement of protons an open issue.…”

“…By going to more negative voltages (sequence >17 in Figure d), superconductivity gets suppressed again. We surmise that oxygen ions, produced previously during water electrolysis, can be pushed into the sample. , They fill the oxygen vacancies and reduce conduction carriers, which tends to drive the sample to an insulator.…”

Ionic gating in the study of superconductivity

“…Möckli和Khodas [66] 认为面内平行磁场将s波 转变为同位旋的f 波, 最终得到s+if非常规超导. Liu [67] , Nakamura和Yanase [68] [76,77] , YBCO [78,79] , La 2 -CuO 4+δ [80] , Pr 2 CuO 4+δ [81] 和NdBaCu 3 O 7 [82] , 以及电子掺 杂的Pr 2−x Ce x CuO 4 [83,84] 和La 2−x Ce x CuO 4 [85,86] . 高T c 的超导态.…”

“…Shimizu等人 [101] [102] . Wei等人 [81] 发现在 Pr 2 CuO 4+δ 的调控中, 正栅压下H + 进入样品引入电子掺 杂, 而负栅压时CuO面上的氧缺陷被修复. Cui等人 [103] 则用核磁共振(NMR)实验证实了H + 注入在系列铁基超 导体(11和122体系)的调控中发挥了重要的作用.…”

Embedded ionic liquid modified ZIF-8 in CaMgAl hydrotalcites for bio-glycerol transesterification

“…However, ionic liquids are not suitable for industrial applications since they are not easily separated and recovered in reaction systems. 15 Thus it is significant to find suitable carriers to prepare heterogeneous catalysts with strong catalytic activity, high stability and easy recyclability in transesterification between glycerol and DMC to prepare GC. 16,17…”
