Light‐Fueled In‐Operando Shape Reconfiguration, Fixation, and Recovery of Magnetically Actuated Microtextured Covalent Adaptable Networks

open access: yesAdvanced Materials, EarlyView.
A covalent adaptable network with dynamic disulfide bonds (DS‐CAN) can rearrange its molecular topology through heating or UV irradiation. When combined with ferromagnetic particles, its photoresponsiveness at room temperature enables contactless, spatiotemporal regulation of dynamic bond exchanges during magnetomechanical actuation.

Performance‐Recoverable Closed‐Loop Neuroprosthetic System

open access: yesAdvanced Materials, EarlyView.
A self‐healing and stretchable bilayer (SSB) electrode with spontaneous performance recovery consists of a nanomembrane (closely packed aligned Pt‐coated Ag nanowires embedded in the self‐healing polymer) and a nanocomposite (Pt‐coated Ag flakes in the self‐healing polymer).

Pairing N‐Vacancy and Adjacent Ni‐Sites in the Local Microenvironment to Regulate the Urea Oxidation Reaction Pathway With Enhanced Kinetics

open access: yesAdvanced Materials, EarlyView.
In nitrogen vacancies‐rich nickel nitride (Ni3N‐VN), a local microenvironment of nitrogen vacancies and adjacent Ni sites is formed. The electron‐rich Ni‐sites can be converted to NiOOH at a lower potential, and urea adsorption on the electron‐deficient nitrogen vacancy region is conducive to its partial dissociation, conceiving to efficient urea ...

Synergistic Cathode‐Electrolyte Engineering for Enhanced Longevity in Li‐S Batteries

open access: yesAdvanced Materials, EarlyView.
Thanks to the synergism of abundant active sites and the superior catalytic effect of the uf‐MBene/CNT cathode host, along with uniform lithium ion deposition facilitated by adding Na2SeO3 additives, the cell with this S@uf‐MBene/CNT cathode and Na2SeO3 additive can maintain stable cycling for up to 850 cycles with a capacity retention rate of 93.6% at

Triboelectric Nanogenerators Enable Multifunctional Ice Accretion, Melting, and Interfacial Fracture Detection

open access: yesAdvanced Materials, EarlyView.
Water impacting, freezing, melting, and being mechanically removed from the designed dielectric surfaces generates a triboeletric signal that can be used to detect various icing and de‐icing scenarios. The charge transferred directly scales with the interfacial fracture mechanism, further validating triboelectricity as an excellent ice‐detection ...
