    Solid polymer electrolytes are crucial for the development of lithium batteries, but their lower ionic conductivity compared with liquid/ceramics at room temperature limits their practical use. Precise positioning of designed repeating units in alternating polymer sequences now allows the Li+ conductivity to be tuned by up to three orders of magnitude.

    The two-dimensional layered crystal structure of niobium oxide polymorph T-Nb2O5 exhibits fast Li-ion diffusion that is promising for energy storage applications. Epitaxial growth of single-crystalline T-Nb2O5 thin films with ionic transport channels oriented perpendicular to the surface are now demonstrated.

    Silicon-based complementary metal-oxide semiconductors or negative differential resistance device circuits can emulate neural features, yet are complicated to fabricate and not biocompatible. Here, the authors report an ion-modulated antiambipolarity in mixed ion–electron conducting polymers demonstrating capability of sensing, spiking, emulating the most critical biological neural features, and stimulating biological nerves in vivo.

    Despite recent progress in the synthesis and characterization of molybdenum disulphide, little is yet known about its microstructure. Using refined chemical vapour deposition synthesis, high-quality crystals of monolayer molybdenum disulphide have now been grown. Single-crystal islands and polycrystals containing tilt and mirror twin grain boundaries are characterized, and the influence of the grain boundaries on the material properties of molybdenum disulphide is assessed.
