A Touch Enabled Hemodynamic and Metabolic Monitor

open access: yesAdvanced 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.

Mechanistic Insights into the Structural Evolution of ZIF‐67 via Electrospinning Strategy Toward High Electromagnetic Wave Absorption Performance of ZIF‐67‐Derived Carbon Nanofibers

open access: yesAdvanced Science, EarlyView.
With 5G and AI robotics rising, electromagnetic radiation risks signal security and health. This work investigates the electromagnetic wave absorption of Co/CNF composites via in situ and ex situ electrospinning strategies. The in situ synthesized sample exhibits superior absorption properties due to enhanced structural uniformity, improved Co ...

Separating the Role of Mixing‐Entropy on the Dynamics of Glass‐Forming Liquids

open access: yesAdvanced Science, EarlyView.
This research innovates by distinguishing entropy’s impact from enthalpy in materials through micro‐alloying. It finds liquid fragility decreases with minimal alloying content or increased element diversity. This clarifies entropy’s role and supports the entropy‐driven glass transition, guiding new material design.
