Bioinspired Oxygen‑Enriched Nanodiamonds as Electrolytic Erythrocyte Mimics for Dendrite‑Free Zinc‑Ion Batteries

open access: yesAdvanced Science, EarlyView.
Inspired by the cyclic transport of oxygen from the lungs (high‑O2 region) to tissues (low‑O2 region), oxygen‑enriched nanodiamond (OND) is introduced into aqueous zinc‑ion batteries as “electrolyte erythrocytes.” These OND repeatedly shuttle Zn2+ from high‑ to low‑concentration regions, dramatically flattening the Zn2+ gradient and thereby effectively

Active Thermal Metasurfaces Enable Superscattering of Thermal Signatures Across Arbitrary Shapes and Thermal Conductivities

open access: yesAdvanced Science, EarlyView.
This study proposes a thermal superscatterer capable of manipulating thermal scattering signatures far exceeding the actual scale of objects. Utilizing transformation thermotics and active thermal metasurfaces, the device reproduces the thermal scattering signature of the enlarged thermal scatterer.
