Ultrathin Polymer Electrolyte With Fast Ion Transport and Stable Interface for Practical Solid‐state Lithium Metal Batteries

open access: yesAdvanced Materials, EarlyView.
High‐performance ultrathin (≈7.8 µm) polycarbonate‐based electrolyte (UPCE) is fabricated, without the use of additional liquid additives. The designed UPCE delivers a high ionic conductivity (4.8 × 10−4 S cm−1) and an ultrahigh critical current density (11.5 mA cm−2) at 25 °C.

Nitrogen‐Doped Amorphous Carbon Film for Enhanced Cu2+ Electrochemical Sensing in Marine Environments

open access: yesAdvanced Materials Interfaces, EarlyView.
Large‐area N‐doped amorphous carbon films are synthesized at room temperature via hybrid linear ion source technique. Nitrogen doping promotes the formation of sp2−C and C‐N bonds, thus enhancing the electrode's sensitivity. These electrodes achieve ultra‐low Cu2+ detection (8 × 10−3 mM) in 3.5 wt% NaCl and exhibit excellent stability/repeatability for

Implantable Microarray Patch: Engineering at the Nano and Macro Scale for Sustained Therapeutic Release via Synthetic Biodegradable Polymers

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This review focuses on the application of synthetic biodegradable microarray patches (MAPs) in sustained drug delivery. Compared to conventional MAPs which release drugs into the skin in an immediate manner, these implantable MAPs release drugs into skin microcirculation gradually as the biodegradable polymers degrade, thus offering sustained release ...

Effect of nose bluntness and afterbody shape on aerodynamic characteristics of a monoplanar missile concept with bodies of circular and elliptical cross sections at a Mach number of 2.50 [PDF]

open access: yes
The tests were performed at a Mach number of 2.50 and at angles of attack from about -4 deg to 32 deg. The results indicate that increasing nose bluntness increases zero lift drag and decreases both the maximum lift-drag ratio and the level of ...

Electrical Metamaterial‐Based Interconnects‐Enabled Highly Stretchable Wireless Electrocardiography Circuit

open access: yesAdvanced Materials Technologies, EarlyView.
This article presents a novel strategy for creating highly stretchable wireless circuits using electrical metamaterial‐based interconnects (EMIs). Embedded in soft polymers and filled with liquid metal, EMIs uniquely reduce resistance under strain. A fully integrated ECG circuit demonstrates reliable performance under 100% stretch, offering a highly ...
