Controlled co-precipitation and thermal treatment produce rod-like high-entropy oxides with narrow particle sizes, lower overpotential, and higher surface area.
Controlled Ta, Ba, and Sm substitution in tungsten bronze ceramics raises Q and keeps resonant frequency stable across temperature changes.
Colloid-mill mixing separates nucleation and growth to produce more uniform lithium oxide precursors with higher throughput for battery cathodes.
Tuned tungsten bronze ceramic compositions raise RF Q while keeping resonant frequency stable across temperature changes.
