Understanding the Role of Nb Doping in Modulating Ionic Diffusion Kinetics and Particle Size in Spinel LiMn2O4

Battery Energy, Volume 5, Issue 1, January 2026.
Niobium (Nb) incorporation into spinel LiMn2O4 achieves simultaneous enhancement of ionic diffusion kinetics and particle size. After Nb doping, the overall surface energy decreases, promoting particle growth. Despite the increased particle size, the introduction of niobium significantly improves the rate capability and effectively mitigates ...

Lead‐Free (K0.5Na0.5)NbO3 Unmodified Piezoceramics: A Reduction in the Energetic Budget of Solid State Synthesis and Sintering

Chemistry–Methods, Volume 5, Issue 12, November 2025.
The temperature of the solid‐state synthesis of pure (K0.5Na0.5)NbO3 piezo‐composition is reduced by using the niobium pentoxide reactant in the mixture of reagents after attrition milling for only 3h: a majoritarian (57 wt.% of the total Nb2O5 content) orthorhombic polymorph Pbam.
