WebSupported graphene oxide membrane is endowed with selective function for olefins by a cation intercalation method. The metal-cation fixed GO membrane exhibits a high propane to propylene ideal selectivity of 1817 for single gas and a separation factor of 7.1 for binary mixture with the fast gas permeance in the order of 10-7 mol m-2 s-1 Pa-1 and the … Web13 apr. 2024 · Highly stable metal oxide thin film transistors (TFTs) are required in high-resolution displays and sensors. Here, we adopt a tantalum cation (Ta5+) doping method to improve the stability of zinc–tin–oxide (ZnSnO) TFTs. The results show that Ta5+-doped TaZnSnO TFT with 1 mol% concentration exhibits excellent stability. …
