Electrospun Vanadium Pentoxide (V2O5) Nanofibers for Enhanced Humidity Sensing

open access: yesAdvanced Sensor Research, EarlyView.
Vanadium pentoxide (V2O5) nanofibers (NF) fabricated via electrospinning are analyzed and used for room‐temperature humidity sensing. Optimally performing porous NFs (∅ 200–500 nm) with high surface area (14.8 m2 g−1) are achieved at an annealing temperature of 500 °C.

Metal‐Free Raman Sensing Platforms of Organic Nanowire Arrays Produced by High Energy Charged Particles

open access: yesAdvanced Sensor Research, EarlyView.
A freestanding purely organic nanowire array (ONA) structure is fabricated to maximize the surface area with the designed surface affinity for analyte molecules. The designed electron transfer reactions between the analytes and nanowires provide Raman signal enhancement factors of up to 108 with the detection limit of the analytes as 10−9 M for the ...

Cost‐Effective Hierarchical Cobalt Nanostructured Laser‐Induced Graphene for Enhanced Uric Acid Detection

open access: yesAdvanced Sensor Research, EarlyView.
A one‐step electrochemical strategy is utilized to develop a flexible, enzyme‐free biosensor for the sensitive detection of uric acid (UA). The hierarchical cobalt nanostructures synergistically enhance the performance of the biosensor, resulting in a broad detection range of 5 to 700 µM with a sensitivity of 6.75 µA µM−1 cm−2 and a low detection limit

Enhanced Oxygen Evolution Reaction Performance of Niobium–Cobalt Oxide Catalysts in Acidic and Alkaline Media

open access: yesAdvanced Sustainable Systems, EarlyView.
The electronic modulation of Nb‐doped Co3O4 catalyst showcases enhanced activity and extended stability for OER in both alkaline (1M KOH) and acidic (0.5M H2SO4) electrolytes. The higher activity emanated from the synergistic effect between the Nb5+ dopant and Co3O4.
