Electrical Conductivity of Hydrous SiO2: Implications for the Superionic State and High Conductivity Anomalies Beneath Subduction Zones

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Electrical conductivity (EC) is a key physical property of minerals and rocks that constrains the composition and structure of Earth's deep interior. Theoretical studies predict that the CaCl2‐type hydrous Al‐bearing SiO2 phase, present in subducted crustal materials, becomes superionic—where protons are no longer bonded to specific oxygen ...

Ti3C2Tx MXene‐Zirconium Diboride Based Ultra‐High Temperature Ceramics

Advanced Science, Volume 12, Issue 23, June 20, 2025.
This study demonstrates the effectiveness of Ti3C2Tx MXenes as additives in ultra‐high‐temperature ceramics (ZrB₂), enhancing densification, reducing oxygen content, and improving mechanical properties. Through surfactant‐free electrostatic self‐assembly and spark plasma sintering, MXenes enabled the formation of a core–shell microstructure, resulting ...
