Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Sodium‐ion batteries (SIBs) offer a promising, cost‐effective alternative for large‐scale energy storage due to the abundance of sodium. However, their practical deployment is challenged by sluggish interfacial kinetics and unstable interphase formation, which severely limit performance across wide temperature ranges. Here, we demonstrate that

Electrically Switchable Altermagnetism in Monolayer MoCl3
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Altermagnets intertwine spin‐split bands with vanishing net magnetization, offering great potential for high‐density, stray‐field‐free spintronic devices. However, their development is hindered by both material scarcity and difficulties in external control due to their intrinsic symmetry protection.

Iron Ore Pricing in China: Financialization Through a Marxist Lens
Abacus, Volume 62, Issue 3, Page 922-956, September 2026.We offer a Marxist interpretation of financialization as we examine the Chinese market for iron ore and the shift in the pricing mechanism from an annual fixed price to an indexed price from 2010. Drawing upon Marx's theory of the circuit of capital, we illustrate an empirical case of financialization that results from the conflict between social ...
