Functional Ecology, Volume 40, Issue 2, Page 534-552, February 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Non‐structural carbohydrates (NSC) are critical mediators of plant adaptation to fluctuating light environments. They are tightly coordinated with plant economic strategy, that is, leaf economics spectrum (LES) and root economics spectrum (RES).

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Transition metal carbides demonstrate exceptional mechanical properties but confront a critical hardness–toughness trade‐off. Spinodal decomposition‐mediated phase separation is an effective approach to enhance mechanical properties in carbide ceramics through high‐temperature treatment.
