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.

Chitosan, Gelatine, and Cellulose Based Hydrogels for the Removal of Potentially Toxic Elements from Aquaculture Water: A Comparative Study

open access: yesAdvanced Sustainable Systems, EarlyView.
Hydrogels made of chemically modified biopolymers are easy to prepare and cost‐effective, they have proven to be effective materials for the simultaneous removal of seven potentially toxic elements (PTEs) from ultrapure and real water samples. The cellulose‐based one seems the best for single treatments while the gelatine‐based one seems the most ...
