Overcoming Out‐of‐Plane Conduction by Changing Nanosheet Morphology
Advanced Science, EarlyView.HTaWO6 membrane made of stacked nanotubes exhibits high out‐of‐plane proton conductivity of 1.7 mS/cm. High current density (1.26 A cm−2) and power density (294 mW cm−2) indicate the potential as a fuel‐cell electrolyte. The morphology‐driven strategy establishes topology engineering as a new design principle for efficient ion transport in two ...

Technology for creating a photonic integrated circuit on a lithium niobate substrate
Компьютерная оптикаWe propose a new technology for manufacturing a photonic integrated circuit (PIC) on a lithium niobate substrate. It is shown that there is no need to dope the top layer of lithium niobate to create a waveguide system and control radiation.

Advanced Electronic Materials, EarlyView.Electrodeposition is explored as an innovative and scalable approach to fabricate standardized and highly piezoelectric chitosan films. Chitosan deposition is driven onto gold‐coated silicon plates by an applied voltage. Films’ piezoelectricity is clearly proved and correlated to the material structural order.
