Effect of Composition on Grain‐Boundary Chemistry and Fracture Behavior in High‐Entropy Carbides

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT High‐entropy carbides (HECs) are often treated as a single material class defined by configurational entropy; however, their properties are governed by composition‐specific defects and grain‐boundary chemistry. This study demonstrates that substituting a single element can qualitatively change grain‐boundary structure and fracture behavior in ...

Fluorescent MIL‐53(Al) Enhanced 3D Printing of Si3N4 Ceramics via Vat Photopolymerization

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT Vat photopolymerization (VPP) has recently been applied to fabricate silicon nitride (Si3N4) ceramics. To overcome limitations in Si3N4 slurry curing performance, a multi‐functional modification strategy utilizing the metal‐organic framework MIL‐53(Al) was proposed.

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures

Advanced Engineering Materials, Volume 28, Issue 8, 22 April 2026.
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed
