Cat‐Vibrissa‐Inspired Biomass Fiber Aerogels for Flexible and Highly Sensitive Sensors in Monitoring Human Sport

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by cat vibrissae, biomimetic biomass PHFs/SA aerogels (BFAs) are developed via precursor‐assisted in situ polymerization and freeze‐synergistic assembly. These ultralight, porous pressure sensors exhibit high sensitivity and excellent durability, enabling pulse detection, handwriting recognition, Morse code transmission, and notably real‐time ...

Strategic Design of Oxophilic Dopants for Active and Durable Alkaline Hydrogen Evolution Reaction Under Seawater

open access: yesAdvanced Functional Materials, EarlyView.
This study explores a cost‐effective alternative by incorporating oxophilic dopants into non‐precious metal hosts to enhance water dissociation and catalyst stability. Computational screening identified Ni─V, Ni─Mo, and Co─V as top candidates. Subsequent experiments confirmed Ni20V exhibits superior HER activity, achieving 76 mV lower overpotential ...
