Tailoring Monovalent Ion Sieving in Graphene-Oxide Membranes with High Flux by Rationally Intercalating Crown Ethers.

Two-dimensional membranes have shown promising potential for ion-selective separation due to their well-defined interlayer channels. However, the typical "trade-off" effect of throughput and selectivity limits their developments. Herein, we report a precise tailoring of monovalent cation sieving technology with enhanced water throughput via the intercalation of graphene-oxide membranes with selective crown ethers.

A two-dimensional superlattice membrane enables high-performance desalination and enhanced Li ion selectivity.

Here, we report a two-dimension (2D) superlattice-like membrane composed of periodic MoS and GO nanosheets, which delivers enhanced salt rejection capability, high water flux, and Li ion selectivity. It opens a new perspective in assembling 2D membranes and can be utilized as a green and low-cost approach for desalination.

Low-Temperature Synthesis of Lithium Lanthanum Titanate/Carbon Nanowires for Fast-Charging Li-Ion Batteries.

Due to the lower working voltage and higher capacity, the Li-rich lithium lanthanum titanate perovskite (LLTO) anode is becoming a potential candidate for the commercial LiTiO (LTO) Li-ion battery anode [Zhang, L. Lithium Lanthanum Titanate Perovskite as an Anode for Lithium Ion Batteries. 2020, 11, 3490].
