Hierarchically structured (Co1/3Fe2/3)Se2nanofibers with fiber-in-tube nanostructures were prepared by an electrospinning process and subsequent selenization. The synergetic effects of the hierarchical structures and ultrafine nanorods with high electrical conductivity resulted in superior rate performance of the hierarchically structured (Co1/3Fe2/3)Se2nanofibers.

Sodium ion-conductive silicon nitride ceramic with Na2O–Al2O3–SiO2 glass as the grain boundary phase was fabricated by adding Na2CO3, Al2O3, and SiO2 as sintering additives. The electrical conductivity was two and four orders of magnitude higher than that of Si3N4 ceramic with Y2O3 and Al2O3 additives at 100 and 1000°C, respectively. This result clearly indicates that ionic conductivity can be provided to insulating structural ceramics by modification of the grain boundary phase without dispersion of conductive particles.
