Single‐source precursor synthesis of a compositionally complex early transitional metal nitride (V, Nb, Ta, Mo, W)Nx and its high temperature stability

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract Compositionally complex transitional metal nitrides are an interesting class of ceramics with superior chemical, thermal, and mechanical stability, with a high potential in ultra‐high temperature applications and catalysis. The exceptionality in the properties may partly be explained as a consequence of their high configuration entropy ...

Octahedral tilting and ferroelectric order in tetragonal Tungsten bronze-like dielectrics

, 2007
The onset of classic ferroelectric behavior in tetragonal tungsten bronze-like dielectrics Ba2LaxNd1-xNb3Ti2O15 was attributed to a strong coupling between local polar displacements and a certain type of octahedral tilting.
