Sustainable High‐Performance Aqueous Batteries Enabled by Optimizing Electrolyte Composition

Advanced Science, EarlyView.
Lithium‐free aqueous batteries provide a safe, low‐cost alternative to lithium‐ion batteries for energy storage. This study introduces an optimized electrolyte using inexpensive salts, enhancing both energy density and cycling stability. The resulting battery delivers high power and efficiency, demonstrating strong potential for supercapacitor ...

A Touch Enabled Hemodynamic and Metabolic Monitor

Advanced Science, EarlyView.
This work presents a touch‐based hybrid platform for simultaneous monitoring of vital signs and sweat metabolites. With a simple tri‐finger touch of 4–6 min, users can concurrently get to know their glucose, uric acid, cortisol levels from fingertip sweat, along with blood pressure and heart rate.

Reliably In‐Memory Ternary Stateful Logic Computing Based on Tri‐State Memristors with High On/Off Ratio

Advanced Electronic Materials, EarlyView.
A tri‐state Ag/Al2O3/Ta2O5/Pt memristor is introduced to in‐memory stateful logic circuits. The stepped I–V characteristics enable the experimental implementations of the ternary logic gates in a crossbar array. The decoder function is demonstrated using cascaded ternary NOT and NOR gates.

Interface Topology and Wetting Dynamics of Laser‐Induced Bonds Between Aluminum Foil and Silicon Nitride Passivation in Solar Cells

Advanced Energy Materials, EarlyView.
Metallization in photovoltaics faces challenges due to silver dependency. This study explores Laser Metal Bonding (LMB), an ultra‐rapid, ablation‐free process enabling robust aluminum‐to‐silicon nitride connections while preserving passivation layers and cell efficiency. Combining experiments and simulations, key adhesion mechanisms, thermal thresholds,
