Summary: The market for flexible, hybrid, and printed electronic systems is uncertain, but these systems are emerging daily, allowing for devices and systems that can be folded and stored in pockets. Cellulose-based modified nanopapers were developed as a physical support and gate dielectric layer for recyclable field-effect transistors (FETs). Impregnation of the nanopapers with sodium ions enabled low voltage FETs (<3 V), with high mobility (>10 cm2 V-1 s-1), current modulation (>105), and improved dynamic response. These transistors were successfully implemented into simple circuits such as inverters, showing clear discrimination between logic states. Besides improved electrical performance, these devices are a promising alternative for reliable, sustainable, and flexible electronics, even under stress conditions.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
