A Pill That Prints‐An Ingestible Bioprinter for Non‐Invasive Structured Bioink Deposition

open access: yesAdvanced Science, EarlyView.
A first‐of‐a‐kind swallowable bioprinter performs in‐situ bioink deposition and patterning directly over disease sites without tethers, electronics, or invasive surgery. Combining magnetic guidance with near‐infrared triggering enables functionality within a small footprint.

Carboxyl‐Guided Ultrafine Zinc‐Acetate Templating Enables Closed‐Pore Engineering in Coal‐Derived Hard Carbon Anodes for High‐Performance Sodium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
In this study, ≈2 nm zinc acetate templates are uniformly anchored on the surface of NaOH‐etched bituminous coal via chelation between carboxyl groups and Zn2+. Subsequently, phenolic resin encapsulation is employed to construct a hard carbon material with abundant closed‐pore structures, achieving a reversible capacity of 370.9 mAh g−1 and an ICE of ...
