Waste‐Derived Zn‐Based ASEI Layer for Enhanced Lithium Anodes in Lithium–Sulfur Batteries

open access: yesAdvanced Sustainable Systems, EarlyView.
Lithium dendrite formation limits the scalability of lithium‐metal batteries. This study develops a waste‐derived Zn‐based hybrid artificial solid electrolyte interphase (ASEI) layer, enhancing Li anode stability. It achieves a low 9 mV overpotential over 400 cycles and enables high‐capacity Li–S performance (1085 mAh g⁻¹ at 0.1 C).

A Convoy of Magnetic Millirobots Transports Endoscopic Instruments for Minimally‐Invasive Surgery

open access: yesAdvanced Science, EarlyView.
The first electrocautery procedure performed by a team of millirobots (TrainBots) is presented. Enhanced with optimized feet, millirobots form a convoy to facilitate the collaborative transportation of wires and catheters through biological lumens, e.g. bile ducts. It opens up the possibility of using a team of mini‐robots in future endoscopic surgery.

Sustained Vaccine Exposure Elicits More Rapid, Consistent, and Broad Humoral Immune Responses to Multivalent Influenza Vaccines

open access: yesAdvanced Science, EarlyView.
This work presents an injectable polymer‐nanoparticle hydrogel depot platform for delivering multivalent influenza vaccines which induces stronger and more durable immune responses. The technology provides broader protection, including against heterologous and potential pandemic strains (H5N1, H7N9, H9N2), and enhances the effectiveness of commercial ...
