Solid electrolytes based on oxygen ion conductors find extensive applications as devices for oxygen sensor, oxygen pumps, solid oxide fuel cells and electrocatalytic reactors. When using ceramic ionic conductors for applications, frequent attempts are made to improve the performance of the electrochemical system by apply'rig mixed conductors as thin top layers instead of the conventional ir~ert...

Supercapacitor devices are interesting owing to their broad range of applicability from wearable electronics energy storage in electric vehicles. One the key parameters that affect efficiency supercapacitor is selecting ideal electrode material for a specific application. Regarding this, recently developed metal oxides, specifically nanostructured ZnO, and MXenes with defect structures, size ef...

In this study, we report on a combined approach to preparing an active electrode material for supercapattery application by making nanocomposites of Polyaniline/Cerium (PANI/Ce) with different weight percentages magnetite (Fe 3 O 4 ). Fourier-transform infrared spectroscopy (FTIR) and x-ray diffraction (XRD) analyses supported the interaction PANI Ce formation successful nanocomposite nanoparti...

As a novel type of green energy storage device, supercapacitors exhibit several orders magnitude higher capacities than the traditional dielectric capacitors and significantly power density secondary batteries. Supercapacitors have been widely applied in fields. Electrode materials, as pivotal components supercapacitors, play an important role electrochemical performance. Molybdenum-based mater...

This paper presents the details of a novel battery architecture based on superhydrophobic nanostructured materials. Both electrodes of a battery are formed on nanostructured silicon surfaces that are subsequently treated to make them superhydrophobic, effectively separating the liquid electrolyte from the active electrode materials. A phenomenon called electrowetting that promotes electrolyte p...

A key obstacle to practical operation of protonic ceramic fuel cells (PCFCs) is the development of high efficient cathode materials. In this study, we report the identification of Gd0.1Ce0.9O2-d (GDC) infiltrated PrBaCo2O5þd (PBC) e BaZr0.1Ce0.7Y0.2O3-d (BZCY) materials as a novel triple phase (e /Hþ/O2 ) conducting composite cathode of PCFCs. This triple phase conducting composite cathode is c...
