In this study, columbite MgNb2-xTaxO6 (x = 0.0, 0.2, 0.4, 0.6, and 0.8) ceramics are synthesized by a conventional solid-state reaction; the microwave dielectric properties and bond characteristics are investigated with bond-valence theory and structure refinement. The substitution of Ta5+ for...

Understanding the gist of graphene in fluid lubrication is crucial to develop graphene-enhanced industrial lubricants, yet the prerequisite for modulating high-performance graphene hybrid lubricants is to change its inherent surface characteristics and obtain good dispersion stability. Herein,...
