Recent Progress in Oxide‐Based Na‐Ion Conductors

open access: yesAdvanced Engineering Materials, Volume 28, Issue 6, 18 March 2026.
Recent advances in oxide‐based sodium‐ion conductors are reviewed, focusing on β/β″‐alumina, NASICON‐type compounds, and Na5YSi4O12‐type (N5) silicates, together with emerging perovskite and layered oxides. Improvements in ionic conductivity, compositional tuning, and processing are highlighted.

Attribute Implication Bases From Galois Connection Structures

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 4, Page 2729-2753, 15 March 2026.
ABSTRACT Modeling knowledge systems by determining relationships among key variables have been and currently is a fundamental and nontrivial challenge in real‐world scenarios. Many approaches have been developed to reach this goal, but many of them are heuristic and require of alternative procedures to provide robust and tractable rules.
