Commercial Sodium‐Ion Batteries: Understanding Mechanism and Function Using In Operando Neutron Diffraction and X‐Ray Tomography Studies

open access: yesAdvanced Functional Materials, EarlyView.
In operando neutron diffraction reveals the real‐time structural evolution of O3‐type NaxNi1/3Mn1/3Fe1/3O2 in commercial sodium‐ion batteries that is coupled with electrochemical and tomography data. The study establishes a direct link between current‐dependent phase transitions, lattice kinetics, and electrochemical behavior, offering mechanistic ...

Domain Nucleation and Growth in an Epitaxially Grown Wurtzite Ferroelectric

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectric domain nucleation and growth in epitaxial wurtzite (Al, B, Sc)N films are visualized through in situ transmission electron microscopy. Domains initiate near the bottom electrode and propagate laterally with zigzag walls, while unswitched regions remain near the electrode interfaces.

Anti‐Swelling Textile Power Generator with 1D Nanoscale Channel Alignment in Nanofiber/Graphene Hybrid Yarns

open access: yesAdvanced Functional Materials, EarlyView.
A nanofiber/graphene hybrid yarn with 1D oriented nanoscale channel is constructed via bath electrospinning followed by a functionalization process, yielding exceptional anti‐swelling and weaving abilities. When configured into a waterproof fabric through series‐parallel connection of 62‐cm yarns, an output power of 31.96 µW is achieved, which could ...
