A ternary polyaniline/Fe2O3-SnO2/reduced graphene oxide (PFSG) nanocomposite was prepared using a simple two-step hydrothermal treatment. The composite was applied as a glassy carbon electrode modifier (GCE) to enhance dopamine (DA) and uric acid (UA

The energy storage capability of the aqueous supercapacitors is mainly attributed to the relatively low operating voltage of the device, as the thermodynamic decomposition voltage of water is 1.23 V. Therefore, the extension of the working voltage of

This work focused on the development of doping procedures to introduce nitrogen functionalities on an activated carbon derived from anthracene oil to be subsequently used on wide voltage asymmetric capacitors. For that, ammonia solution was used and

Acoustic emission analysis (AEA) results for textural characterization of granular activated carbons (GAC) can be related with its porosity. GACs were evaluated using this AEA technique by band-pass filtering from 3.5 to 50 kHz of the sound produced
