is the study and application
of phenomena, properties, effects and mechanisms of processes connected with
fast ion transport (FIT) in all-solid-state nanoscale systems.
The topics of interest include fundamental properties of oxide ceramics at nanometer length scales, and fast ion conductor
(advanced superionic conductor)/electronic
heterostructures. Potential applications
are in electrochemical devices (electrical double layer devices)
for conversion and storage of energy,
charge and information. The term and conception of nanoionics (as a new
branch of science)
were first introduced by A.L.Despotuli and V.I.Nikolaichik (Institute of
and High Purity Materials, Russian Academy of Sciences,
Chernogolovka) in January 1992.
