Oxygen Ion Conduction in Oxide Materials: Selected Examples and Basic Mechanisms

Boletín de la Sociedad Española de Cerámica y Vidrio, 2006
Oxygen ion conductors with most symmetrical structures such as fluorite- and perovskite-related phases, rely on the mobility of oxygen vacancies. High-performance electrolytes, namely with the apatite type structure, recently developed, show dominant ...

Experimental methods in chemical engineering: Cyclic voltammetry—CV

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Cyclic voltammetry (CV) is a foundational electroanalytical technique for investigating redox behaviour and evaluating material performance across fields such as molecular electrochemistry, electrocatalysis, sensing, and energy storage. Despite its widespread use, a gap remains between formal electrochemical theory and the practical data ...

Organic–Inorganic Composite Nanofibers Based on YSZ Nanofibers Anchored PANI/SnS2 Heterojunction for Flexible Room Temperature NO2 Sensor

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel organic–inorganic YSZ@PANI/SnS2 composite nanofiber film was prepared via an in‐situ construction strategy of a PANI interfacial layer. The biomimetic "branch‐leaf" structure effectively disperses and releases stress and energy, while accelerating gas diffusion/transport and providing abundant active sites.
