Hydrogen‐Bond Symmetrization in Hydrous Aluminous Silica Enhances Deep‐Mantle Water Cycle

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract (Al, H)‐bearing CaCl2‐type SiO2 serves as a key water carrier in Earth's deep‐water cycle. Evolution of hydrogen‐bond symmetrization in this phase was measured up to 62 GPa and 800 K by synchrotron infrared and Raman spectroscopy, and X‐ray diffraction.

The Influence of Field‐Assisted Sintering Technology (FAST) Temperature and Cooling Rate on the Microstructural Evolution in Gamma‐Titanium Aluminide Alloy GE4822

open access: yesAdvanced Engineering Materials, Volume 28, Issue 18, 23 September 2026.
Controlling the Field Assisted Sintering Technology (FAST) parameters, dwell temperature and cooling rate, significantly influences the microstructural evolution in titanium aluminide GE4822. Significant γ‐lamellar colonies develop only upon cooling through the α‐transus.
